Perceived barriers to exercise in people with spinal cord injury

Tele-assessment of activities and participation in chronic phase of stroke: Is use valid and viable in a developing country?

BACKGROUND

SATISPART-Stroke (SATIS-Stroke) is the most complete instrument for the assessment of activity and participation following a stroke. However, its use in a developing country has only been tested through in-person interviews.

OBJECTIVE

To determine the validity, reproducibility and viability of the SATIS-Stroke scale administered in two tele-assessment modalities: self-assessment of an electronic form versus videoconference.

METHODS

Methodological study with Brazilian chronic stroke survivors was conducted. Stage I comprised an in-person interview to apply the SATIS-Stroke and a self-assessment by completing an electronic form to respond to the SATIS-Stroke items. Step II occurred 6 to 8 months after Step I, during which SATIS-Stroke was administered again in-person and via videoconference. The order was randomized.

RESULTS

Ninety-five stroke survivors were recruited, but only 50 answered the electronic form (adherence: 52.6%). Mean scores were higher in the self-administration of electronic form compared to the in-person interview (mean difference = -0.36 ± 0.93; P = 0.009). Adequate reliability was found in the comparison of the in-person and self-assessment of electronic form (ICC2,1 = 0.66; 95%CI: 0.40-0.81). Fifty stroke survivors participated in Step II, during which adequate reliability was found in the comparison of the in-person administration and videoconference (ICC2,1 = 0.55; 95%CI: 0.21-0.74) and a moderate correlation was found between the assessment methods (r = 0.43; P = 0.02).

DISCUSSION

Adequate validity and reliability were found in the tele-assessment. Thus, this method is appropriate and viable for use in developing countries. Although reliable, the self-assessment did not have good adherence in the Brazilian population due to internet access problems, lack of familiarity with the digital form and lack of autonomy to answer the questions alone.

Should I stay or should I go? An exploratory study comparing wheelchair-adapted rowing at home vs. in community gyms

PURPOSE

Wheelchair users experience many barriers to physical activity as affordable and accessible exercise equipment options are limited. Thus, the home-based adapted rower (aROW) and gym-based aROW were developed. The objectives were to determine: 1) wheelchair users' preferences, perspectives, facilitators, and barriers to using the home-based versus the gym-based aROW, 2) perceived usability of the home and gym aROWs, and 3) recommendations to adapt the aROW further for home and community use.

MATERIALS AND METHODS

In this two-phase exploratory mixed-methods study, participants completed one month of using a home aROW, followed by one month of using a community gym aROW. After each phase, participants completed a semi-structured interview and the System Usability Scale (SUS) questionnaire. Interview data were analyzed using conventional content analysis and effect size comparing SUS data was calculated.

RESULTS AND CONCLUSIONS

Four categories were identified: what worked well, barriers to using the aROWs, what could be improved and important considerations. There was a large effect size in perceived usability between the aROWs with participants preferring the home aROW. Overall, rowing was enjoyable, and participants achieved positive physical outcomes. As preferences are individual, the home aROW provides wheelchair users with a potential choice between home or gym exercise.

Health action process approach and spinal cord injury: a scoping review

PURPOSE

Spinal cord injury may result in chronic pain, difficulty walking and breathing, and/or paralysis. People with spinal cord injury (PwSCI) experience increased risk for chronic diseases and psychosocial distress (e.g. type 2 diabetes, substance use disorders) and premature mortality. The Health Action Process Approach (HAPA) is a social cognitive health behavior framework validated to explain modifiable preventative health behaviors (e.g. physical exercise, healthy eating, substance misuse) among people with chronic conditions. The present scoping review investigates what, how, and how much peer-reviewed research literature applies HAPA to preventative health behaviors among PwSCI.

MATERIALS AND METHODS

A search was conducted in seven community health databases including PubMed, CINAHL, PsycINFO, SocIndex, Scopus, Web of Science, Sociological Abstracts, and Library and Information Science Source. Seven peer-reviewed articles were identified. Conventional content analysis was used in the full-text review to identify themes and calculate theme frequency.

RESULTS

All studies were quantitative and applied HAPA to physical exercise. HAPA explained differences in sports participation, leisure time physical activity, and strength training.

CONCLUSIONS

A strong predictor of physical exercise was belief in the capability to overcome psychosocial barriers. More attention is needed on HAPA-identified barriers, and customized HAPA-based interventions to promote physical exercise among PwSCI.

Effectiveness of interventions to increase physical activity in adults with SCI: a systematic review and meta-analysis

PURPOSE

To determine the effectiveness of interventions to increase physical activity (PA) in people with spinal cord injury (SCI).

METHOD

Online databases PubMed, Medline, AMED and CINAHL were searched from the earliest date available to July 2022. Randomised controlled trials (RCT) exploring the effect of interventions on physical activity in people with SCI were eligible. The search identified 1191 studies, after screening 16 reports of 15 RCT's were included. Data were extracted on participant characteristics, intervention characteristics and physical activity outcomes. Methodological quality was assessed using the PEDro Scale and certainty of evidence assessed using GRADE. Post intervention means and standard deviations were pooled in meta-analyses to calculate standardised mean differences or mean differences and 95% confidence intervals.

RESULTS

Fifteen trials with 693 participants (mean age 41-52) were included. There was moderate certainty evidence that exercise interventions had no effect on subjectively or objectively measured PA. There was moderate to high certainty evidence that behavioural interventions and combined behavioural and exercise interventions increased subjectively, but not objectively measured physical activity.

CONCLUSION

Behaviour change techniques are an important intervention component for increasing PA in people with SCI.

Adapted sailing teaching methodology using vsail-trainer simulator as rehabilitation therapy. A feasibility study

Context: Sailing is a sport that can help in the rehabilitation of Spinal Cord Injury (SCI) patients and improve their quality of life. Teaching methodology in sailing has always been considered as complex, due to the great amount of uncertainty that this sport has.Purpose: To design a protocol for teaching adapted sailing in a simulated situation for people with SCI and to know the effect of the teaching protocol on learning, effort perception and heart rate.Method: Six adults were patients recruited at the National Hospital of Paraplegics of Toledo (Spain), aged between 31 and 54 years, who have passed the early subacute phase. Each subject underwent semi-immersive virtual reality sailing therapy for 40 min per session three times per week for six weeks, 18 sessions. A simulated adapted sailing initiation program VSail-Trainer® was used for the simulator therapy. During this session, the basic notions of sailing, wind direction, sheet trimming and control of the boat on different courses were explained. The variables assessed were: sailing learning, heart rate and effort perception.Results: The comparison of performance variables between pretest and posttest resulted differences in boat speed, heel and Velocity Made Good (VMG). These improvements in the performance variables are also reflected in the average times taken by the subjects to complete the regatta.Conclusion: The methodology used in this study can be used as a guide for learning the activity by new SCI patients in rehabilitation who want to get into sailing sport.

Effects of different training methods in tele-exercise on acute performance decrement in adults with disability and wheelchair users

PURPOSE

Wheelchair users and people with disabilities have limited access to physical exercise due to various factors, including medical follow-up and training facilities. Although tele-exercise guided by experts has become a viable option, there is limited knowledge about the acute performance decrement (APD) resulting from remote training methods. The current cross-sectional study aimed to: (1) assess the APD of muscle resistance strength after three synchronous tele-exercise training methods in wheelchair users and (2) compare the training loads associated with each training method.

MATERIALS AND METHODS

Eighteen male and female wheelchair users who participated in tele-exercise strength practices were recruited. The participants performed a maximum resistance strength test by synchronous tele-assessment (push-up test, PUT) at baseline and immediately after three training methods: high-intensity interval training (HIIT), moderate-intensity continuous training (MICT) and sprint interval training (SIT). The primary outcome was the APD, which was measured by the percentage decrease in the number of repetitions of the PUT immediately after the training methods.

RESULTS

APD was observed for all three training methods, with no significant differences between them (-34.8%, -29.9% and -38.0% for MICT, SIT and HII, respectively), and presented a non-significant correlation with the training loads. HIIT had a significantly higher training load than MICT and SIT.

CONCLUSIONS

APD occurred in all training sessions, but did not correlate with training load, indicating that it is not an appropriate metric for comparison. Findings provide insight into APD response and highlight the need to consider multiple metrics when comparing training protocols.

Leisure-time physical activity motives and perceived gains for individuals with spinal cord injury

STUDY DESIGN

Longitudinal cross-sectional.

OBJECTIVES

To examine motives to, and perceived gains from, leisure-time physical activity (LTPA) in people with spinal cord injury (SCI).

SETTING

Community.

METHODS

One hundred and five physically active individuals with SCI undertook an online survey and a semi-structured interview. The Exercise Motives and Gains Inventory was used to examine the movies towards, and the gains from LTPA, and the Leisure-time Physical Activity Questionnaire was administered via interview to gather LTPA data. A cross-sectional analysis, which included descriptive, inferential, and regression statistics, was conducted on all participants, physical activity (PA) guideline adherers and PA guideline non-adherers.

RESULTS

The most common motives for LTPA were improvements in health and fitness, management of appearance and weight, and avoidance of illness. The most common gains from LTPA included improved health, fitness, strength and endurance, increased nimbleness, and enjoyment and revitalisation.

CONCLUSIONS

Whilst health enhancement appears to be a significant motivator for LTPA, other psychosocial aspects, such as affiliation and revitalisation, appear to influence engagement and volume of LTPA. Regular LTPA should be encouraged for its health benefits, and emphasis should be placed on promoting its ability to reduce illness, facilitate affiliation, and manage stress.

Translation, cross-cultural adaptation and reliability testing of the barriers to physical activity and Disability survey (B-PADS) for Thai people with Spinal Cord injury

PURPOSE

The objectives of this study were to translate and culturally adapt the Barriers to Physical Activity and Disability Survey (B-PADS) into the Thai context and to assess its inter- and intra-rater reliability.

METHODS

Participants were experts in the field of spinal cord injury (SCI, n = 3), linguistic experts (n = 7), Thai-English bilingual speakers (n = 40), Thai physiotherapists (n = 8), and people with SCI living in Thailand (n = 43). The translation and cross-cultural adaptation of the B-PADS into the Thai context was conducted using a 6-step process; forward translation, reconciliation of the two translated versions, backward-translation, harmonisation, backward-translation of the revised version, and cognitive debriefing with potential users and target population. The reliability of the translated tool was assessed using Cohen's kappa (K) and McNemar's test.

RESULTS

The inter-rater reliability test demonstrated high-range agreement for the majority of statements (27 out of 38; Cohen's K > 0.60) in the Thai-B-PADS final version. The intra-rater reliability test revealed that the majority of the statements (29 out of 38) in the Thai-B-PADS final version obtained substantial (Cohen's K = 0.61-0.80, p < 0.05) to perfect agreement (Cohen's K = 1.0, p < 0.05). McNemar's test displayed no statistically significant differences amongst assessors (p > 0.05) for nearly all statements.

CONCLUSION

The Thai-B-PADS final version was successfully translated and culturally adapted for people with SCI.

Preliminary observations on the administration of a glucagon-like peptide-1 receptor agonist on body weight and select carbohydrate endpoints in persons with spinal cord injury: A controlled case series

CONTEXT/OBJECTIVE

To describe the effect of semaglutide, a glucagon-like peptide-1 (GLP-1) agonist, to reduce body weight and improve glycemic control in overweight or obese individuals with spinal cord injury (SCI).

DESIGN

Open-label, randomized drug intervention case series.

SETTING

This study was performed at James J. Peters VA Medical Center (JJP VAMC) and Kessler Institute for Rehabilitation (KIR).

PARTICIPANTS

Five individuals with chronic SCI meeting criteria for obesity and abnormal carbohydrate metabolism.

INTERVENTION

Administration of semaglutide (subcutaneously once per week) versus no treatment (control) for 26 weeks.

OUTCOME MEASURES

Change in total body weight (TBW), fat tissue mass (FTM), total body fat percent (TBF%), and visceral adipose tissue volume (VATvol) was determined at baseline and after 26 weeks using Dual energy X-ray absorptiometry; fasting plasma glucose (FPG) concentration and serum glycated hemoglobin (HbA1C) values were obtained at the same two time points.

RESULTS

In 3 participants, after 26 weeks of semaglutide administration, TBW, FTM, TBF%, and VATvol decreased, on average, by 6, 4.4 kg, 1.7%, and 674 cm3, respectively. In addition, values for FPG and HbA1c decreased by 17 mg/dl and 0.2%, respectively. After 26 weeks of observation in the 2 control participants, TBW, FTM, TBF% and VATvol increased on average by 3.3 , 4.5 kg, 2.5%, and 991 cm3, respectively. The average values for FPG and HbA1c also increased by 11 mg/dl and 0.3%, respectively.

CONCLUSIONS

Administration of semaglutide for 26 weeks resulted in favorable changes in body composition and glycemic control, suggesting a reduced risk for the development of cardiometabolic disease in obese individuals with SCI.Trial registration: ClinicalTrials.gov identifier: NCT03292315.

Socio-ecological Barriers to Leisure Time Physical Activity in Spanish Wheelchair Users With Spinal Cord Injury: Associations With Sociodemographic Characteristics and Functional Independence

OBJECTIVE

(1) To assess prevalence and severity of socio-ecological barriers to leisure time physical activity (LTPA) in a sample of adults with spinal cord injury (SCI); (2) to examine the association of these barriers with sociodemographic characteristics and functional independence (FI); and (3) to explore which socio-ecological levels of barriers might be associated with LTPA.

DESIGN

Cross-sectional study.

SETTING

Neurorehabilitation Hospital specialized in SCI.

PARTICIPANTS

207 wheelchair users with SCI living in the community who attended a comprehensive check-up (22.7% women, 47.5±10.7 mean age; N=207).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The short version of the Barriers to Physical Activity Questionnaire for People with Mobility Impairments was used to measure socio-ecological barriers to LTPA. The Spinal Cord Independence Measure III was used to measure FI. The Physical Activity Recall Assessment for People with SCI was used to quantify LTPA. Several multiple linear regression models were computed to examine the associations between socio-ecological barriers and sociodemographic factors, LTPA and FI.

RESULTS

A high prevalence of barriers to LTPA was found. Seven of these barriers (2 intrapersonal, 3 organizational, and 2 community) were present for >60% of the participants. Intrapersonal and organizational barriers had a higher effect on participants with lower FI and women. Interpersonal barriers were higher for older participants and with lower FI, while community barriers were higher for unemployed participants. Finally, intrapersonal and interpersonal barriers were negatively associated with LTPA, and FI revealed as a moderator of the intrapersonal barriers-LTPA relation.

CONCLUSIONS

Given their high prevalence and their association with LTPA, the development of interventions targeting socio-ecological barriers to LTPA in people with SCI becomes crucial. The associations of these barriers with FI and sociodemographic characteristics should also be considered for these interventions to be as specific and effective as possible.

Preliminary feasibility and acute physiological effects of a single session of upper limb vibration training for persons with spinal cord injury

CONTEXT

Strong upper limb musculature is essential for persons with spinal cord injury (SCI) to operate a manual wheelchair and live independently. Targeted upper limb vibration may be a viable exercise modality to build muscle efficiently while eliminating some of the barriers associated with exercise for persons with SCI.

OBJECTIVE

The purpose of this study was to assess preliminary feasibility of completing a single exercise session of upper limb vibration and compare the acute physiological effects to a single session of standard dumbbell resistance exercise.

METHODS

Individuals with SCI performed seven upper limb exercises (1) isometrically using a vibrating dumbbell at 30 Hz for 60 s (n = 22) and (2) using a standard isotonic resistance protocol (n = 15).

RESULTS

Nineteen (86.4%) of 22 participants were able to perform all vibration exercises at 30 Hz but hold time success rates varied from 33% (side flies and front raises) to 95% (internal rotation). No significant differences were found between vibration exercise and standard resistance protocol for blood lactate, power output, and heart rate (P > 0.05). Perceptions of the training were positive, with most participants (>70%) expressing interest to train with vibration in the future.

CONCLUSIONS

Vibration training was not feasible for all participants, suggesting an individualized approach to starting weight and progression may be necessary. Similar acute physiological changes were seen between vibration exercise and standard resistance protocol, suggesting they could have similar benefits. Additional research is needed to determine if vibration exercise is feasible and beneficial to incorporate into a long-term training program.

Patient Perceptions and Clinical Assessments of Cardiometabolic Disease After Subacute Spinal Cord Injury

OBJECTIVES

To investigate the effectiveness of health care team communication regarding cardiometabolic disease (CMD) risk factors with patients with subacute spinal cord injury (SCI).

DESIGN

Multi-site prospective cross-sectional study.

SETTING

Five National Institute on Disability, Independent Living, and Rehabilitation Research Model SCI Rehabilitation Centers.

PARTICIPANTS

Ninety-six patients with subacute SCI, aged 18-70 years, with SCI (neurologic levels of injury C2-L2, American Spinal Injury Association Impairment Scale grades A-D), and enrolled within 2 months of initial rehabilitation discharge (N=96).

INTERVENTIONS

None.

MAIN OUTCOME MEASURE(S)

Objective risk factors of CMD (body mass index, fasting glucose, insulin, high-density lipoprotein cholesterol, triglyceride levels, and resting blood pressure). Patient reported recall of these present risk factors being shared with them by their health care team. Medications prescribed to patients to address these present risk factors were checked against guideline- assessed risk factors.

RESULTS

Objective evidence of 197 CMD risk factors was identified, with patients recalling less than 12% of these (P<.0001) being shared with them by their health care team. Thirty-one individuals (32%) met criteria for a diagnosis of CMD, with only 1 of these patients (3.2%) recalling that this was shared by their health care team (P<.0001). Pharmacologic management was prescribed to address these risk factors only 7.2% of the time.

CONCLUSIONS

Despite high prevalence of CMD risk factors after acute SCI, patients routinely do not recall being told of their present risk factors. Multifaceted education and professionals' engagement efforts are needed to optimize treatment for these individuals.

Cardiac autonomic nervous activity during different sleep stages in individuals with spinal cord injury: The influence of physical training

OBJECTIVE

The present study assessed the influence of physical training on cardiac autonomic activity in individuals with spinal cord injury (SCI) during different sleep stages.

METHODS

Twenty-six volunteers were allocated into three groups: 9 sedentary individuals without SCI (control, CON); 8 sedentary tetraplegic individuals with chronic SCI (SED-SCI); 9 physically trained tetraplegic individuals with chronic SCI (TR-SCI). All participants underwent nocturnal polysomnography to monitor sleep stages: wakefulness, non-rapid eye movement (NREM) sleep (N1, N2, and N3 stages), and REM sleep. The electrocardiography data obtained during this exam were extracted to analyze the heart rate variability (HRV).

RESULTS

Sleep stages influenced HRV in the time [RR interval and root mean square of successive RR interval differences (RMSSD)] and frequency [low-frequency (LF) and high-frequency (HF) powers and LF-to-HF ratio] domains (P < 0.05). SED-SCI individuals showed unchanged HRV compared to CON (P > 0.05). When comparing the TR-SCI and SED-SCI groups, no significant differences in HRV were reported in the time domain (P > 0.05). However, in the frequency domain, more accentuated HF power was observed in TR-SCI than in SED-SCI individuals during the N2 and N3 stages and REM sleep (P < 0.05). Moreover, TR-SCI had higher HF power than CON during the N3 stage (P < 0.05).

CONCLUSIONS

TR-SCI individuals have greater HF power, indicative of parasympathetic modulation, than sedentary (injured or not injured) individuals during different sleep stages. Therefore, enhanced parasympathetic activity induced by physical training may improve cardiac autonomic modulation during sleep in individuals with chronic SCI.

Developing and Evaluating Data Infrastructure and Implementation Tools to Support Cardiometabolic Disease Indicator Data Collection

Background

Assessment of aerobic exercise (AE) and lipid profiles among individuals with spinal cord injury or disease (SCI/D) is critical for cardiometabolic disease (CMD) risk estimation.

Objectives

To utilize an artificial intelligence (AI) tool for extracting indicator data and education tools to enable routine CMD indicator data collection in inpatient/outpatient settings, and to describe and evaluate the recall of AE levels and lipid profile assessment completion rates across care settings among adults with subacute and chronic SCI/D.

Methods

A cross-sectional convenience sample of patients affiliated with University Health Network's SCI/D rehabilitation program and outpatients affiliated with SCI Ontario participated. The SCI-HIGH CMD intermediary outcome (IO) and final outcome (FO) indicator surveys were administered, using an AI tool to extract responses. Practice gaps were prospectively identified, and implementation tools were created to address gaps. Univariate and bivariate descriptive analyses were used.

Results

The AI tool had <2% error rate for data extraction. Adults with SCI/D (n = 251; 124 IO, mean age 61; 127 FO, mean age 55; p = .004) completed the surveys. Fourteen percent of inpatients versus 48% of outpatients reported being taught AE. Fifteen percent of inpatients and 51% of outpatients recalled a lipid assessment (p < .01). Algorithms and education tools were developed to address identified knowledge gaps in patient AE and lipid assessments.

Conclusion

Compelling CMD health service gaps warrant immediate attention to achieve AE and lipid assessment guideline adherence. AI indicator extraction paired with implementation tools may facilitate indicator deployment and modify CMD risk.

Adherence and perceptions of a home sports video gaming program in persons with spinal cord injuries: A pilot study

OBJECTIVE

Sports video-gaming can facilitate increased activity levels in persons with limited exercise options. Understanding how persons with spinal cord injuries (SCI) participate in home-based video-gaming and its potential impact on maintaining or enhancing physical function remains largely unexplored. The purpose of this study was to evaluate adherence, perceptions, and potential physical effects of a home sports video-game program for persons with chronic SCI.

PARTICIPANTS

Fourteen individuals with chronic SCI (9 tetraplegia, 5 paraplegia).

DESIGN

This was a prospective study. Wii video-gaming systems that included four sports games were provided to participants for home use. Participants were instructed to play for 8 weeks 3-4 days/week. The video consoles recorded the time and number of sessions played.

OUTCOME MEASURES

At baseline and at the conclusion of the program, measurements were made of upper extremity strength, perceived exertion, active heart rate, pain, balance, and a functional upper extremity (UE) test. The total time and number of sessions were compared to the prescribed game play as a measure of adherence. Scores from a self-reported survey were used to gauge participants' satisfaction and perceptions of their gaming experience.

RESULTS

Overall mean gaming adherence was 85% during the first 4 weeks and 69% for the second 4 weeks. There were no significant changes in upper extremity strength, active heart rate, balance, pain, or functional UE test for either group. All of the participants rated video gaming as enjoyable and 85.7% perceived that it could be used as a form of exercise.

CONCLUSION

The Wii sports home video-gaming intervention elicited overall high adherence rates and was well received by study participants indicating that it may have value as an adjunctive tool for increasing physical activity for individuals with SCI.

Interpersonal counseling versus active listening in the treatment of mild depression: a randomized controlled trial

[Purpose] Healthcare workers, such as physical therapists, need to be equipped in dealing with patients' psychological problems. The three-session interpersonal counseling (three-session IPC) is a constructed counseling method that can be performed even by non-mental health professionals. This study examined the efficacy of the three-session IPC for treating depression. Immediate efficacy and efficacy up to 12 weeks post-intervention were examined. [Participants and Methods] In this randomized controlled trial of the two groups, one group (n=24) received the three-session IPC therapy (IPC group) while the other (n=24) received three sessions of active listening (active listening group). Depression was assessed using the Self-Rating Depression Scale (SDS) at baseline, post-intervention, and at 4, 8, and 12 weeks. [Results] There was a significant difference in total SDS scores between the IPC and active listening groups from baseline to 4 weeks after counseling, although no significant differences were observed at other time points. [Conclusion] The three-session IPC may be effective for 4 weeks after counseling. However, further studies are warranted in this regard.

Barriers to Physical Activity for Women with Physical Disabilities: A Systematic Review

Physical activity is essential for women with physical disabilities. This review aims to identify the barriers they face in practicing sport. A systematic review was conducted using the PubMed/Medline, Scopus, and Web of Science databases in January 2023, with an update in March 2023. The eligibility criteria used for inclusion were as follows. (i) Women with physical disabilities; (ii) women who engage in or want to engage in physical activities and/or sport, both adapted and non-adapted; (iii) identification of women's barriers to such practice; (iv) research articles; and (v) papers written in English and published in peer-reviewed journals. The exclusion were as follows. (i) Women with illness, injury or transient physical activity difficulties; (ii) mention of rehabilitative physical activity; and (iii) results showing no differentiation in barrier types by gender. This review identified different barriers, grouped into eight types according to the differentiating factor, thus showing that disable people's participation in physical activity is directly related to some specific barriers which seem to differ according to their gender. Therefore, the success of participation in physical activities depends not only on the user's concern, but also on an inclusive social environment.

High-Intensity Functional Training: Perceived Functional and Psychosocial Health-Related Outcomes from Current Participants with Mobility-Related Disabilities

BACKGROUND

People with mobility-related disabilities (MRDs) experience many personal and environmental barriers to engagement in community-based exercise programs. We explored the experiences of adults with MRD who currently participate in high-intensity functional training (HIFT), an inclusive and accessible community-based exercise program.

METHODS

Thirty-eight participants completed online surveys with open-ended questions, with ten individuals also participating in semi-structured interviews via telephone with project PI. Surveys and interviews were designed to examine changes to perceived health, and the elements of HIFT that promote sustained participation.

RESULTS

Thematic analysis revealed themes related to health changes following HIFT participation including improved physical, functional, and psychosocial health outcomes. Other themes emerged within the HIFT environment that promoted adherence for participants such as accessible spaces and equipment, and inclusive HIFT sessions and competitions. Additional themes included participants' advice for the disability and healthcare communities. The resulting themes are informed by the World Health Organization's International Classification of Functioning, Disability, and Health.

CONCLUSION

The findings provide initial data on the potential effects of HIFT on multiple dimensions of health outcomes and contribute to the growing literature on community-based programs that are adaptable and inclusive for people with MRD.

Measurement properties of outcome measures used in neurological telerehabilitation: A systematic review using COSMIN checklist

OBJECTIVE

To summarize the measurement properties (reliability, validity, and responsiveness) and the clinical utility of measurement tools used in telerehabilitation in individuals with neurological conditions.

DESIGN

Systematic review.

SUBJECTS

Individuals with neurological conditions.

INTERVENTION

Not applicable.

MAIN MEASURES

The methodological quality of the studies using the COSMIN Risk of Bias Checklist, the quality of the measurement properties using the criteria for good measurement properties, and the clinical utility of the measurements using the Tyson & Connell scale.

RESULTS

From the 22,188 identified studies, 47 were included. Forty-three measurement tools were identified. The main modes of administration were telephone and videoconference. Studies involved mostly individuals with stroke, multiple sclerosis, and Alzheimer's disease. Criterion validity and reliability were the most investigated measurement properties. None of the tools had their responsiveness investigated. Twenty-two measurement tools have at least one measurement property evaluated as "sufficient" in a study with appropriate methodological quality ("very good" or "adequate"). Nineteen measurement tools showed adequate clinical utility. Eight measurement tools, investigated in individuals with stroke, spinal cord injury or Alzheimer's disease, all administered by telephone, were recommended.

CONCLUSION

The present results can be used to assist in choosing appropriate measurement tools, both in research and clinical practice, during telerehabilitation in individuals with neurological conditions. Measurement error, content validity, structural validity, and responsiveness need to be further investigated. In addition, the measurement properties of tools used in telerehabilitation in other neurological conditions, such as Huntington's disease, should also be investigated.

Potential of social engagement for overcoming barriers to physical activity in individuals with spinal cord injury

Introduction

Many barriers to physical activity (PA) exist for individuals with spinal cord injury (SCI). Social engagement may improve motivation to perform PA, which in turn may increase PA levels. This pilot study investigates how social engagement facilitated by mobile technology may reduce lack of motivation as a barrier to PA in individuals with SCI and demonstrates design implications for future technologies.

Methods

A user-needs survey was conducted with participants in the community. We recruited 26 participants (16 individuals with SCI and 10 family members or peers). A participatory design process using semi-structured interviews was used to identify themes relating to PA barriers.

Results

One theme related to PA barriers was lack of PA-focused forums to connect with peers. Participants with SCI considered connecting with other individuals with SCI more motivating than connecting with their family members. Another key finding was that participants with SCI did not perceive that personal fitness trackers were targeted towards wheelchair-based activities.

Conclusions

Engagement and communication with peers who have similar functional mobility levels and life experiences can potentially improve motivation for PA; however, PA-motivational platforms are not tailored towards wheelchair-users. Our preliminary findings show that some individuals with SCI are not satisfied with current mobile-technologies for wheelchair-based PA.

Assessing physical activity and health-related quality of life in individuals with spinal cord injury: a national survey in Thailand

PURPOSE

This study sought to; (i) investigate the proportion of Thai individuals with spinal cord injury (Thai-SCI) who met SCI-specific physical activity (PA) guidelines, (ii) describe PA and health-related quality of life (HRQOL) of Thai-SCI across different sociodemographic strata, and, (iii) measure the variance in HRQOL associated with the intensity and volume of leisure-time physical activities (LTPA).

METHODS

Two surveys, measuring PA and HRQOL, were used in this study. Descriptive analysis, parametric and non-parametric tests for comparing two or more groups were used to analyse the data. The relationship between PA levels and HRQOL scores was investigated using Spearman's correlation coefficients. All statistical significance level in this study were set to alpha < 0.05.

RESULTS

From the 200 participants, 14.5% met aerobic, 20.5% met strength training and 13.5% met both aerobic and strength training SCI-specific PA guidelines. Sedentary Thai-SCI accounted for 49% of the study sample. Thai-SCI spent 132.0 ± 254.3 (mean ± SD) minutes per week on moderate-to-heavy intensity LTPA. Average Physical and Mental Component Summary (PCS and MCS scores) of Thai-SCI were 42.3 ± 7.6 and 49.3 ± 8.4 (mean ± SD), respectively. Increases in average LTPA of moderate-to-heavy intensities were weakly correlated with increases in PCS scores and its sub-domains (r = 0.1-0.3, n = 200, all p < 0.05).

CONCLUSION

The average time spent on moderate-to-heavy intensity ADLs and LTPA were below SCI-specific PA guidelines and the WHO global recommendations for PA. The proportion of Thai-SCI who were sedentary was high, suggesting immediate action and implementation of strategies to promote PA for Thai-SCI.IMPLICATIONS FOR REHABILITATIONThe proportion of Thai people with spinal cord injury with a sedentary lifestyle was high.Healthcare providers in Thailand must engage to a greater degree in health-related physical activity promotion to effectively deliver physical activity and exercise knowledge to their clients with spinal cord injury.Likely, structured programs of physical activity and exercise deployed by healthcare professionals with the appropriate knowledge and skills might reverse the current trend to sedentary lifestyle in this population.Interventions to improve participation in physical activity and health-related quality of life should be tailored to the individual needs of Thai individuals with a spinal cord injury and might be better delivered seperately.

A Study on the Establishment of Physical Activity Environment for People with Disabilities in South Korea

The purpose of this study was to analyze the relative importance and priority of what factors should be reflected in the administration to efficiently consider the needs of people with disabilities for the physical activity (PA) environment in South Korea. To achieve the purpose of the study, 32 experts (e.g., faculty members, administrators) with more than 5 years of experience with PA for people with disabilities were asked to prioritize the factors that should be reflected in the PA environment. The questionnaire consisted of 4 factors in the upper-layer (H2), 8 factors in the middle-layer (H3), and 38 items in the low-layer (H4). The research instrument was composed of a pairwise comparison of decision elements to analyze the priority. For the analysis of the questionnaire data, the relative importance and priority were analyzed using Expert Choice 2000, a solution dedicated to priority analysis. The results are as follows. The relative importance of H2 was determined by programs, instructors, facilities, and information. In the relative importance among H3, the program type was determined as the highest factor in the program, and instructor expertise was determined as the highest factor in the instructor. The type of facility was determined as the highest factor in the facility, and the information provider was determined as the highest factor in the information. As a result of analyzing the priority of H4, it was found that the program within the sports facilities had the highest priority.

Qualitative analysis of perceived motivators and barriers to exercise in individuals with spinal cord injury enrolled in an exercise study

STUDY DESIGN

Cross-sectional.

OBJECTIVES

Examine exercise perceptions of SCI individuals enrolled in an exercise trial about their: (a) reasons for enrolling, (b) barriers to exercise, and (c) solutions to address barriers.

SETTING

World-wide web.

METHODS

US individuals ≥18 years old with SCI completed password-protected free-response surveys (n = 144) as part of a larger internet-based intervention to promote exercise. Participants' online reporting about their motivations to exercise, barriers, and solutions to identified barriers were analyzed using an inductive thematic qualitative approach. Participants could enter up to 10 responses for each category.

RESULTS

Study staff analyzed 956 participant responses across questions regarding their motivations, barriers, and solutions. Leading reasons reported for enrolling were to improve their physical health (69%), function (61%), and attitude (59%) while commonly reported barriers were time constraints (54%), lack of motivation (31%), accessibility issues (24%), and SCI-specific barriers (23%). Participant-generated solutions were scheduling exercise (47.9%) for time constraints, making exercise more fun (21.8%) to increase motivation, obtaining home exercise equipment (30.3%), and locating accessible facilities (27.3%) to resolve accessibility barriers. Solutions for SCI-specific barriers of temperature control, skin breakdown, and pain included getting adapted equipment or finding exercises they could perform independently (29.3%) and enlisting support from friends or family (24.4%).

CONCLUSIONS

The results offer insights about exercise motivators and barriers reported by people with SCI who enrolled in an exercise intervention program and offer insights regarding topics to address for SCI-tailored exercise programs. Further research should examine what strategies are most useful in helping people with SCI engage in exercise.

Telehealth high-intensity interval exercise and cardiometabolic health in spinal cord injury

BACKGROUND

The number of exercise trials examining cardiometabolic outcomes in spinal cord injury (SCI) is low, and prescribed exercise is often inconvenient for individuals with SCI to perform within their community. Individuals with SCI experience a myriad of barriers to exercise participation, which can include a lack of time, accessible or usable equipment and facilities, and transportation. Thus, it is imperative to identify effective modes of exercise that provide the greatest overall health benefits but do not require a significant time commitment. Low-volume high intensity interval training (HIIT) has demonstrated the same improvements in cardiometabolic health as moderate intensity exercise training (MIT), despite only requiring 20% of the total time commitment in adults without disabilities and more recently in individuals with SCI.

OBJECTIVES

The primary purpose of this study is to integrate a 16 week home-based telehealth HIIT arm crank exercise training program in individuals with SCI and assess changes in cardiometabolic health.

METHODS

Men and women between the ages of 19 and 60 with a confirmed diagnosis of SCI between C7 and T12 will be recruited for this study. Participants will be randomized to 16 weeks of telehealth HIIT exercise two days per week or a no-exercise control group. Aerobic capacity, muscular strength, blood lipids, glucose tolerance, resting energy expenditure, blood pressure, and body composition will be assessed at baseline and 16 weeks post-training.

DISCUSSION

Inactivity associated with SCI leads to chronic cardiometabolic health conditions. The majority of exercise interventions to date show that exercise is capable of increasing physical function, aerobic capacity, and muscle mass, and strength. Additionally, we have recently shown the ability of HIIT to improve blood lipid and glucose concentrations. Advances in telehealth exercise approaches have improved the capability to prescribe home-based exercise programs. Therefore, we hypothesize that the utilization of a home-based telehealth HIIT program will improve cardiometabolic health markers, yield high adherence (> 75%), and will be more enjoyable in individuals with SCI.

The Diagnosis and Management of Cardiometabolic Risk and Cardiometabolic Syndrome after Spinal Cord Injury

Individuals with spinal cord injuries (SCI) commonly present with component risk factors for cardiometabolic risk and combined risk factors for cardiometabolic syndrome (CMS). These primary risk factors include obesity, dyslipidemia, dysglycemia/insulin resistance, and hypertension. Commonly referred to as "silent killers", cardiometabolic risk and CMS increase the threat of cardiovascular disease, a leading cause of death after SCI. This narrative review will examine current data and the etiopathogenesis of cardiometabolic risk, CMS, and cardiovascular disease associated with SCI, focusing on pivotal research on cardiometabolic sequelae from the last five years. The review will also provide current diagnosis and surveillance criteria for cardiometabolic disorders after SCI, a novel obesity classification system based on percent total body fat, and lifestyle management strategies to improve cardiometabolic health.

Physical activity promotion in persons with spinal cord injuries: Barriers and facilitators in low-resource communities

Background

A spinal cord injury is a devastating and life-changing event that presents the affected individual with multiple challenges throughout life. Physical activity can help mitigate some of these challenges; however, in low-resource communities where opportunities for physical activity are scarce, these challenges are often exacerbated and multiple.

Objective

This study aimed to identify the barriers and facilitators to physical activity, specifically in individuals with spinal cord injuries, in low-resourced communities.

Methods

A total of 57 adults (> 20 years) with a spinal cord injury living in the Western Cape, South Africa completed the self-developed research questionnaire.

Results

A total of 289 barriers and 290 facilitators were reported. The most frequently reported barriers were lack of transport (n = 35), impairment type (n = 32), lack of trained volunteers and appropriate programmes (n = 19 each) and lack of information received from therapists following discharge (n = 10). The most frequently reported facilitators were support from family (n = 38), the ‘enjoyment’ of physical activity and the fact that ‘it made me feel good’ (n = 37); safe and accessible facilities were reported by 25 participants and 12 participants reported that higher-quality programmes and better-trained staff would help them to be more physically active.

Conclusion

Individuals with a spinal cord injury face many barriers in being physically active. Yet it is evident that people with spinal cord injuries in low-resourced communities are eager to participate and improve their health and physical function. However, this will only realise if practitioners reduce the barriers to access, provide relevant training to staff and volunteers, educate their patients about the importance of physical activity post discharge, and create tailored programmes in safe and accessible community facilities.

Designing accessible educational resources for people living with spinal cord injury

Context/objective: To identify themes of interest for the production of educational resources for people with spinal cord injury (SCI).Design: A mixed-method study.Setting: Outpatient SCI community in Australia.Participants: Individuals with a SCI, or carers, family & friends of people who live with a SCI (n = 116).Interventions: Not applicable.Outcome measures: Quantify themes of interest perceived within the Australian SCI community as necessary for the development of SCI educational resources.Results: All seven individuals from the focus-group interviews suggested that educational resources on body physiology, secondary complications, injury pathophysiology, and health and wellbeing maintenance would be most pertinent for development. These themes (among others) were further explored and quantitatively evaluated via an online survey which demonstrated that interviewees ranked 'Your injury' as being of highest importance for the production of educational resources. Within each theme, the sub-categories; 'Bowel/bladder' and 'What equipment is covered in the National Disability Insurance Scheme (NDIS)' were ranked as being of highest importance for the production of educational resources.Conclusion: We have identified multiple areas of interest in the design and production of educational resources for individuals with SCI.

Measurement properties of outcome measures used in neurological telerehabilitation: A systematic review protocol

Several measurement tools commonly used in face-to-face neurological rehabilitation have been used in telerehabilitation. However, it is not known whether these tools have adequate measurement properties and clinical utility. This systematic review aims to investigate the measurement properties and the clinical utility of measurement tools used in telerehabilitation in individuals with neurological diseases. A systematic review to investigate the measurement properties and clinical utility of measurement tools used in telerehabilitation in individuals with neurological conditions will be conducted. This systematic review will follow the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statement. this systematic review protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) on 28 May 2021 (registration number: CRD42021257662). Electronic searches will be performed in following databases: Medical Literature Analysis and Retrieval System Online (MEDLINE Ovid), Excerpta Medica Database (Embase Classic + Embase Ovid), Physiotherapy Evidence Database (PEDro), Scientific Electronic Library Online (Scielo), and Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS). Two trained independent reviewers will select the studies according to the inclusion criteria, and will also extract the data, evaluate the clinical utility and methodological quality. The relevant data such as design, participants, settings, and mode of administration, measurement properties, and clinical utility will be summarized. Disagreements between reviewers will be resolved by consensus or by the decision of a third independent reviewer. Hand searches of other relevant studies will be employed. The COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) checklist and the clinical utility scale will be used to assess the methodological quality and clinical utility of these tools, respectively. This systematic review will provide information regarding the measurement properties and the clinical utility of the measurement tools used in neurological telerehabilitation. This information will be useful to assist health professionals in choosing adequate measurement tools and planning new research studies.

A national survey of physical activity after spinal cord injury

Physical activity is a powerful modifiable risk factor for disease and mortality. Physical activity levels in people with spinal cord injury (SCI) have not been quantified relative to uninjured individuals in a large population-based sample. We aimed to quantify and compare physical activity in people with and without SCI, and to examine the associations between physical activity, lifestyle, and socioeconomic factors. The 2010 Canadian Community Health Survey (n > 57,000) was used, which includes three measures that assess physical activity levels (i.e., leisure time activity frequency, leisure time activity intensity, and transportation time activity intensity). Bivariable and multivariable logistic regressions were performed and odds ratios (ORs) with corresponding 95% confidence intervals (CIs) were estimated. The odds of physical activity in people with SCI were 0.43 (95% CI 0.3–0.61), 0.53 (95% CI 0.36–0.75), and 0.42 (95% CI 0.28–0.61), across the three measures of physical activity, respectively. These differences persisted after adjustment for lifestyle, comorbidities, and socioeconomic factors. Physical activity is reduced in the SCI population compared with the general population. This knowledge is important to direct future research and guide the allocation of health care resources.

Effects of Paraplegia Fitness Integrated Training on Physical Function and Exercise Self-Efficacy and Adherence Among Individuals With Spinal Cord Injury

Objective

To determine the effects of the Paraplegia Fitness Integrated Training (PARAFiT) program, which is an integrated graded physical exercise and health education program for individuals with spinal cord injury (SCI).

Methods

This nonrandomized single-blind study included 44 participants, who were assigned to either an intervention (PARAFiT) group or an active control (conventional physiotherapy) group. The intervention group underwent the PARAFiT program (8 weeks), which consisted of circuit-based interval training, progressive upper limb resistance training, and health education sessions. During the unsupervised period, the intervention group continuously underwent health education program once a month for 2 months (8 weeks). Repeated-measures analysis of variance was used for the analysis.

Results

The intervention group presented with a higher level of physical activity than did the control group; however, the difference was not significant (p=0.36). Additionally, the intervention group presented with better exercise self-efficacy and cardiorespiratory fitness and stronger bilateral shoulder muscle and handgrip than did the control group (all p<0.05). Exercise adherence was higher in the intervention group than in the control group during both the supervised (80% vs. 75%) and unsupervised (40% vs. 20%) periods.

Conclusion

The PARAFiT program enhanced the level of physical activity, exercise self-efficacy, physical fitness, and exercise adherence among the patients with SCI. Future studies should incorporate guidelines for home-based exercises and regular monitoring to promote long-term adherence to exercise and physical activity among individuals with SCI.

The Relationship between Physical Activity Level and Functional Status of Subjects with High Spinal Cord Injury

BACKGROUND

Spinal cord injuries are one of disability in Poland and in the world.

METHODS

80 subjects with a transverse injury of the cervical spinal cord were enrolled in the study. The study group included men aged 20-50, 33.1 ± 7.5. A total of 40 (50%) of the subjects comprised the physically active group (AG)-subjects doing wheelchair sport twice a week for 90 min a day. The physically inactive group (IG) comprised 40 (50%) subjects who had not participated in any sports activities. Statistical analyses were carried out using Shapiro-Wilk W-test and Mann-Whitney U test.

RESULTS

Significant differences were found between the physically active and inactive men with regard to their functionality status. The biggest differences were found for turning over (p < 0.001) and in adopting a sitting position (p < 0.001). Persons in the AG group had better results in all assessed activities. The biggest differences were observed in the field of toilet and dressing up: tooth-brushing p < 0.007 and washing the top part of the body p < 0.002.

CONCLUSIONS

People participating in regular physical activity-wheelchair rugby-after spinal cord injury have a better relationship with better fitness, greater independence and a better functional status.

Home-Based Tele-Exercise in Musculoskeletal Conditions and Chronic Disease: A Literature Review

Exercise training is an essential component in the treatment or rehabilitation of various diseases and conditions. However, barriers to exercise such as the burdens of travel or time may hinder individuals' ability to participate in such training programs. Advancements in technology have allowed for remote, home-based exercise training to be utilized as a supplement or replacement to conventional exercise training programs. Individuals in these home-based exercise programs are able to do so under varying levels of supervision from trained professionals, with some programs having direct supervision, and others having little to no supervision at all. The purpose of this review is to examine the use of home-based, tele-exercise training programs for the treatment of different disease states and conditions, and how these programs compare to conventional clinic-based exercise training programs.

"It Helps Me With Everything": A Qualitative Study of the Importance of Exercise for Individuals With Spinal Cord Injury

Background

The influence of exercise after spinal cord injury (SCI) is a topic important to both clinicians and researchers. The impact of exercise for individuals with SCI is often studied quantitively, with a large focus on the physiological adaptations to exercise intervention.

Objectives

This study explores individualized experiences of exercise for people with SCI.

Methods

A phenomenological approach was utilized to qualitatively study the experiences of exercise for 16 individuals with SCI.

Results

Participants described multiple benefits of exercise, including increased independence, improved mental health, and increased engagement in social activity.

Conclusion

This study provides novel information about attitudes toward exercise held by individuals with SCI and a more thorough understanding of concepts that are well researched.

Feasibility of a virtual service delivery model to support physical activity engagement during the COVID-19 pandemic for those with spinal cord injury

BACKGROUND

The current pandemic has reduced access to safe, monitored physical activity (PA) programs for persons with spinal cord injury (SCI). The use of telerehabilitation has the potential for continuing activity engagement without risking virus exposure. The present study evaluates the feasibility and efficacy of an online group-based PA program for persons with SCI.

METHODS

This preliminary pre-post study delivered an online group-based PA program to persons with SCI. The program consisted of 1-hour sessions twice weekly for six weeks. Online PA satisfaction questionnaires were assessed at post-treatment. Psychosocial subscales from the NeuroQOL-SF were assessed.

RESULTS

Participants were adult females between 3 and 32 years post-injury, 1 tetraplegic and 3 paraplegics (n = 4). All participants were highly satisfied with the online instruction, overall content, and videoconferencing platform. Participants stated that the online program was beneficial for their overall physical and psychosocial wellbeing. The program resulted in improvement in anxiety and satisfaction with social roles and activities.

CONCLUSION

The current pilot study demonstrates the acceptability and limited efficacy of an online PA program for those with SCI. The program resulted in improved overall perceived wellbeing and satisfaction with social roles and activities. These results have important implications for the clinical implementation of online PA programs in a hospital and community setting.

Passive leg cycling increases activity of the cardiorespiratory system in people with tetraplegia

Individuals with cervical spinal cord injury (SCI) are at an increased risk for cardiovascular disease. Exercise is well-established for preventing cardiovascular disease, however, there are limited straightforward and safe exercise approaches for increasing the activity of the cardiorespiratory system after cervical SCI. The objective of this study was to investigate the cardiorespiratory response to passive leg cycling in people with cervical SCI. Beat-by-beat blood pressure, heart rate, and cerebral blood flow were measured before and throughout 10 minutes of cycling in 11 people with SCI. Femoral artery flow-mediated dilation was also assessed before and immediately after passive cycling. Safety was monitored throughout all study visits. Passive cycling elevated systolic blood pressure (5±2 mmHg), mean arterial pressure (5±3 mmHg), stroke volume (2.4±0.8 mL), heart rate (2±1 beats/min) and cardiac output (0.3±0.07 L/min; all p<0.05). Minute ventilation (0.67±0.23 L/min), tidal volume (70±30 mL) and end-tidal PO2 (2.6±1.23 mmHg) also increased (all p<0.05). Endothelial function was improved immediately after exercise (1.62±0.13%, p<0.01). Passive cycling resulted in one incidence of autonomic dysreflexia. Therefore, passive leg cycling increased the activity of the cardiorespiratory system, improved endothelial function, indicating it may be a beneficial exercise intervention for the cardiovascular and respiratory systems in people with cervical SCI. Novelty: ● Passive leg cycling increases the activity of the cardiorespiratory system and improves markers of cardiovascular health in cervical SCI. ● Passive leg cycling exercise is an effective, low-cost, practical, alternative exercise modality for people with cervical SCI.

Genomic and Epigenomic Evaluation of Electrically Induced Exercise in People With Spinal Cord Injury: Application to Precision Rehabilitation

OBJECTIVE

Physical therapists develop patient-centered exercise prescriptions to help overcome the physical, emotional, psychosocial, and environmental stressors that undermine a person's health. Optimally prescribing muscle activity for people with disability, such as a spinal cord injury, is challenging because of their loss of volitional movement control and the deterioration of their underlying skeletal systems. This report summarizes spinal cord injury-specific factors that should be considered in patient-centered, precision prescription of muscle activity for people with spinal cord injury. This report also presents a muscle genomic and epigenomic analysis to examine the regulation of the proliferator-activated receptor γ coactivator 1α (PGC-1α) (oxidative) and myostatin (hypertrophy) signaling pathways in skeletal muscle during low-frequency (lower-force) electrically induced exercise versus higher-frequency (higher-force) electrically induced exercise under constant muscle recruitment (intensity).

METHODS

Seventeen people with spinal cord injury participated in 1 or more unilateral electrically induced exercise sessions using a lower-force (1-, 3-, or 5-Hz) or higher-force (20-Hz) protocol. Three hours after the exercise session, percutaneous muscle biopsies were performed on exercised and nonexercised muscles for genomic and epigenomic analysis.

RESULTS

We found that low-frequency (low-force) electrically induced exercise significantly increased the expression of PGC-1α and decreased the expression of myostatin, consistent with the expression changes observed with high-frequency (higher-force) electrically induced exercise. Further, we found that low-frequency (lower-force) electrically induced exercise significantly demethylated, or epigenetically promoted, the PGC-1α signaling pathway. A global epigenetic analysis showed that >70 pathways were regulated with low-frequency (lower-force) electrically induced exercise.

CONCLUSION

These novel results support the notion that low-frequency (low-force) electrically induced exercise may offer a more precise rehabilitation strategy for people with chronic paralysis and severe osteoporosis. Future clinical trials are warranted to explore whether low-frequency (lower-force) electrically induced exercise training affects the overall health of people with chronic spinal cord injury.

Physical Activity and Health-Related Quality of Life in Adults With a Neurologically-Related Mobility Disability During the COVID-19 Pandemic: An Exploratory Analysis

Background: During the coronavirus-19 (COVID-19) pandemic various containment strategies were employed. Their impact on individuals with neurological conditions, considered vulnerable to COVID-19 complications, remains to be determined.

Objective: To investigate associations between physical activity and health-related quality of life outcomes in individuals with a neurological condition during government mandated COVID-19 restrictions.

Methods: An e-survey assessing fear of COVID-19, physical activity level and health-related quality of life outcomes (functional disability and pain, anxiety and depression, loneliness, fatigue, and vitality) was distributed to individuals with a neurologically-related mobility disability living in the United Kingdom. Open-ended questions were also included to contextualize barriers and facilitators to engage in physical activity during the COVID-19 pandemic. Gamma-weighted generalized linear models and tree-structured regression models were employed to determine the associations between physical activity and health-related quality of life.

Results: Of 199 responses, 69% reported performing less physical activity compared to pre-pandemic. Tree-structured regression models revealed that lower leisure-time physical activity was significantly associated (p ≤ 0.009) with higher depression and fatigue, but lower vitality. The closure of leisure facilities and organized sport (27%) was the most commonly cited barrier to engage in physical activity, while 31% of participants mentioned concerns around their physical and mental health as a facilitator.

Conclusion: Our analysis identified homogenous subgroups for depression, fatigue, and vitality based specifically on leisure-time physical activity cut points, irrespective of additional demographic or situational characteristics. Findings highlight the importance of and need to safely promote leisure-time physical activity during the COVID-19 pandemic in this at-risk population to help support health-related quality of life.

Quality of Life and Physical Activity of Persons with Spinal Cord Injury

The higher quality of life of people with spinal cord injury is closely related with their reintegration into the social environment. Social reintegration is a demanding and complex process, requiring individuals to become active again and acquire age-, gender-, and culture-appropriate roles and social status. It also involves independence and productive behavior as part of multiple interpersonal relationships with family, friends, and others. In order to establish whether individuals with spinal cord injury who are physically active subjectively rate their quality of life to be higher compared to those who are not, sixty-two respondents from Slovenia with spinal cord injury were interviewed. Thirty-one of them were physically active, and 31 were not. The level of injury of the responders was from Th6–Th12. The participants gave the highest assessments to their interpersonal relationships, and the lowest to their satisfaction with material prosperity. Data comparison showed that subjective estimates in all areas of quality of life are higher in respondents who were involved in physical activity after their injury. The results may encourage persons with spinal cord injury to participate more often in sports programs, and also encourage others to do so.

Assessing factors associated with social connectedness in adults with mobility disabilities

BACKGROUND

People with mobility disabilities are likely to report limitations in community participation and social connectedness for a variety of reasons, including inaccessible physical environments, health issues, transportation barriers, and limited financial resources. Improving social connectedness is a public health issue and research shows its relation to overall health and life expectancy.

OBJECTIVE

The purpose of this study was to (1) assess social activity, isolation, and loneliness among people with mobility disabilities compared to those with non-mobility disabilities and (2) understand factors associated with social connectedness among people with mobility disabilities.

METHODS

An observational, cross-sectional analysis was conducted using data from Wave 2 of the National Survey on Health and Disability (NSHD) to test for differences between adults age 18-64 with mobility disabilities (n = 621) and those with other disabilities (n = 1535), in addition to tests within the mobility disability group.

RESULTS

Adults with mobility disabilities were less likely than respondents from other disability groups to report feeling isolated (30.2% versus 35.2%), but these groups did not differ on measures of social activity or loneliness. Within the mobility disability group, being unemployed and in fair or poor health were predictive of greater loneliness, more isolation, and less satisfaction with social activity.

CONCLUSIONS

Social connectedness is an important public health issue. This research helps to inform service providers and medical professionals about the personal factors affecting social connectedness among people with mobility disabilities.

The Spinal Cord Injury Program in Exercise (SCIPE) study: study protocol for a randomized controlled trial evaluating teleexercise programs for people with spinal cord injury

BACKGROUND

Many people with spinal cord injury (SCI) have limited access to tailored, readily available exercise resources. As a result, exercise remains an underutilized treatment strategy for improving health and function in people with SCI. The purpose of this study is to test the effectiveness of two remotely delivered exercise programs for people with SCI.

METHODS

The Spinal Cord Injury Program in Exercise (SCIPE) study is a three-arm adaptive randomized controlled trial examining two 8-week teleexercise interventions: Movement-to-Music (M2M) and Standard Exercise Training (SET), compared to Attention Control (AC) in 327 adults with SCI. The primary outcome is change in physical activity level at post 8-week intervention. The study contains two interim analyses. The first interim analysis will assess feasibility metrics of the protocol after 36 participants complete the 8-week intervention period. The second interim analysis will examine two effectiveness comparisons: SET vs. AC and M2M vs AC, after 165 participants complete the intervention period. Early termination of the intervention arm(s) will take place when non-significant findings are found in the corresponding intervention(s). Incorporation of such interim analysis enhances trial efficiency by dropping the intervention(s) that deemed ineffective. It provides ethical benefits and allows allocation of additional resources to explore the effective intervention(s).

DISCUSSION

Delivery of teleexercise programs may be an effective strategy for addressing transportation barrier to exercise resources and increasing physical activity level and quality of life in people with SCI.

Virtual Strategies for the Broad Delivery of High Intensity Exercise in Persons With Spinal Cord Injury: Ongoing Studies and Considerations for Implementation

Spinal cord injury (SCI) results in a multitude of metabolic co-morbidities that can be managed by exercise. As in the non-injured population, manipulation of exercise intensity likely allows for fruitful optimization of exercise interventions targeting metabolic health in persons with SCI. In this population, interventions employing circuit resistance training (CRT) exhibit significant improvements in outcomes including cardiorespiratory fitness, muscular strength, and blood lipids, and recent exploration of high intensity interval training (HIIT) suggests the potential of this strategy to enhance health and fitness. However, the neurological consequences of SCI result in safety considerations and constrain exercise approaches, resulting in the need for specialized exercise practitioners. Furthermore, transportation challenges, inaccessibility of exercise facilities, and other barriers limit the translation of high intensity "real world" exercise strategies. Delivering exercise via online ("virtual") platforms overcomes certain access barriers while allowing for broad distribution of high intensity exercise despite the limited number of population-specific exercise specialists. In this review, we initially discuss the need for "real world" high intensity exercise strategies in persons with SCI. We then consider the advantages and logistics of using virtual platforms to broadly deliver high intensity exercise in this population. Safety and risk mitigation are considered first followed by identifying strategies and technologies for delivery and monitoring of virtual high intensity exercise. Throughout the review, we discuss approaches from previous and ongoing trials and conclude by giving considerations for future efforts in this area.

The effects of COVID-19 restrictions on physical activity and mental health of children and young adults with physical and/or intellectual disabilities

BACKGROUND

COVID-19 has caused unprecedented restrictions, significantly affecting the most vulnerable groups in society, such as those with a disability.

OBJECTIVE

The aim of the study was to investigate the effects of COVID-19 lockdown restrictions on physical activity and mental health of children and young adults with physical and/or intellectual disabilities.

METHODS

The study was a cross-sectional design. Parents/carers completed an electronic survey in the UK between June-July 2020 on behalf of their child. Through Likert scales and free-text questions, the survey asked about physical activity levels and mental health during lockdown compared to before, access to specialist facilities and equipment to aid with physical activity, and the short- and long-term concerns around ongoing lockdown restrictions.

RESULTS

Generally, respondents reported negative effects of lockdown restrictions, with 61% reporting a reduction in physical activity levels and over 90% reporting a negative impact on mental health (including poorer behaviour, mood, fitness and social and learning regression). Many respondents cited a lack of access to specialist facilities, therapies and equipment as reasons for this, and raised concerns about the long-term effects of this lack of access on their child's mental health and physical activity levels.

CONCLUSIONS

The survey highlights the negative impact of the COVID-19 lockdown on the physical activity levels and mental health of children and young adults with disabilities and highlights the importance of addressing the needs of the disabled community as restrictions are eased.

Feasibility of an Internet-Based Intervention to Promote Exercise for People With Spinal Cord Injury: Observational Pilot Study

BACKGROUND

People with spinal cord injury (SCI) are less likely to be physically active and have higher chronic disease risk than those in the general population due to physical and metabolic changes that occur postinjury. Few studies have investigated approaches to promote increased physical activity (PA) for people with SCI despite evidence that they face unique barriers, including lack of accessible transportation and exercise equipment. To address these obstacles, we adapted an evidence-based phone-delivered intervention that promoted increased PA among people with SCI into a web-based platform, titled the Workout on Wheels internet intervention (WOWii). The adapted program provides participants with weekly skill-building information and activities, basic exercise equipment, and ongoing support through weekly group videoconferencing.

OBJECTIVE

This pilot study was conducted to assess the feasibility of using a web-based and virtual format to deliver the WOWii program in a randomized controlled trial.

METHODS

We assessed the feasibility of the web-based program by delivering an abbreviated, 4-week version to 10 participants with SCI. Rates of weekly videoconference attendance, activity completion, and exercise activity as tracked by an arm-based activity monitor were recorded for all participants.

RESULTS

Participants averaged 3.3 of 4 (83%) weekly group videoconferences attended, 3.4 of 4 (85%) web-based module activities completed, and 2.3 of 4 (58%) weeks of using the arm-based activity monitor. The majority of the sample (9/10, 90%) synced their arm-based PA monitor at least once, and overall engagement as an average of each component across the 4 weeks was 75%.

CONCLUSIONS

The intervention had sufficiently high levels of engagement to be used in a full randomized controlled trial to test its effectiveness in improving levels of PA among people with SCI. The knowledge we gained from this pilot study informed improvements that were made in the full randomized controlled trial.

Dietetics After Spinal Cord Injury: Current Evidence and Future Perspectives

Following spinal cord injury (SCI), individuals are at high risk for obesity and several chronic cardiometabolic disorders due to a deterioration in body composition, hypometabolic rate, and endometabolic dysregulation. Countermeasures to the consequences of an SCI include adopting a healthy diet that provides adequate nutrition to maintain good body habitus and cardiometabolic health. A proper diet for individuals with SCI should distribute carbohydrates, protein, and fat to optimize a lower energy intake requirement and should stress foods with low caloric yet high nutrient density. The purpose of this article is to present available evidence on how nutritional status after SCI should advance future research to further develop SCI-specific guidelines for total energy intake, as it relates to percent carbohydrates, protein, fat, and all vitamins and minerals, that take into consideration the adaptations after SCI.

Factors associated with leisure-time physical activity participation among individuals with spinal cord injury who ambulate

PURPOSE

The purpose of this study was to employ the theoretical domains framework (TDF) to identify behaviour change factors related to leisure-time physical activity (LTPA) in spinal cord injury (SCI) ambulators.

METHODS

A cross-sectional design was employed. Among 43 SCI ambulators, the TDF behaviour change factors were assessed, along with the duration, types, and intensities of LTPA performed over the previous week.

RESULTS

The TDF behaviour change factors identified as barriers to LTPA included: knowledge, beliefs about capabilities, coping planning, and goal conflict. Approximately 71.81 mins/day (SD = 75.41) was spent doing LTPA. Participants reported aerobic and resistance training activities, along with several other types of LTPA (e.g., rock climbing). Coping planning, action planning, goal conflict, and skills explained significant variance in time spent on LTPA (R²_adjusted = 0.259, p < 0.01), but only action planning uniquely predicted LTPA.

CONCLUSIONS

Greater use of coping and action planning, lower levels of goal conflict and stronger skills were associated with greater participation in LTPA. These factors will be targeted for a future LTPA-enhancing intervention for SCI ambulators, informed by behaviour change theory. SCI ambulators participate in a surprisingly wide range of LTPA. Rehabilitation specialists can use this list to suggest activities for patients with SCI who ambulate.IMPLICATIONS FOR REHABILITATIONBarriers to leisure-time physical activity for individuals with spinal cord injury (SCI) who ambulate include lack of knowledge, weak beliefs about capabilities, lack of coping planning, and high goal conflict.Physical activity interventions for individuals with SCI who ambulate should include action and coping planning, goal conflict, and skills.Physical activity interventions should be created systematically using behaviour change theory and involvement of stakeholders throughout the development process.Practitioners can promote skills training in adapted activities like gardening, cycling, and rock-climbing for ambulators with SCI.

Exploring exercise participation and the usability of the adaptive rower and arm crank ergometer through wheelchair users' perspectives

PURPOSE

Arm crank ergometry and adaptive rowing are existing exercise options for wheelchairs users, but not commonly available. This study was conducted to explore exercise participation of wheelchair users, as well as the usability of the adaptive rowing ergometer (aROW) and arm crank ergometer (ACE).

METHODS

This mixed-methods study used a concurrent triangulation design. Following completion of both exercise sessions (5 min each), participants (n = 14) with spinal cord injury/disease (SCI/D) completed the System Usability Scale (SUS), and a semi-structured interview. Participants were asked about the use of both exercise modalities, and general exercise participation. SUS data were analyzed using a paired sample t-test and qualitative data were analyzed through conventional content analysis.

RESULTS

Wheelchair users exercised for improved physical and mental health, as well as for functional independence, and community participation; however, lack of accessible equipment was a prominent barrier. Both the aROW and ACE have high usability, but the aROW was perceived as more enjoyable and effective for cardiovascular exercise.

CONCLUSIONS

The implementation of the aROW into community gyms has the potential to help close the existing gap in inclusive equipment and may help people with disabilities to be more fully included in their community and lead healthier lives.Implications for rehabilitationWheelchair users perceive exercise as a meaningful activity that enhances physical health and risk of disease, functional independence, community participation, and overall social and emotional health.The adapted rowing machine was perceived as highly usable and was felt to be more enjoyable and effective for cardiovascular exercise compared to traditional arm crank ergometers.The adaptive rower provides an additional accessible equipment option for wheelchair users to obtain effective cardiovascular exercise.More available equipment may increase community participation and promote inclusion for wheelchair users.

Health provider identified barriers and facilitators to weight management for individuals with spinal cord injury

Study Design:

Qualitative descriptive study using semi-structured interviews

Objective:

The purpose of this study was to examine the barriers and facilitators of weight management in individuals with spinal cord injury (SCI) from the perspective of SCI health care providers.

Setting:

Veterans Health Administration and Midwest Regional SCI Care Systems

Methods:

Health care providers (n=25) who care for individuals with SCI completed semi-structured interviews. Thematic analysis methodology was used to identify emergent themes around barriers and facilitators to weight management in SCI.

Results:

Sixteen subthemes emerged for barriers and 7 subthemes emerged for facilitators for weight management in SCI. Barriers included individual-level factors (e.g., physical ability/mobility limitations, lack of interest, psychological obstacles, lack of knowledge, poor dietary strategies), socio-environmental factors (e.g., challenges with family support, lack of access to weight management resources, dependency on others, difficulties obtaining weight measurement), and organizational factors (e.g., lack of integration/ inconsistent weight management support from healthcare systems, pushing calorie intake early post-injury). Facilitators included individual-level factors (e.g., motivation, education/knowledge, participation in exercise and physical activity) and socio-environmental factors (e.g., positive support network, access to/use of healthy dietary strategies, access to exercise facilities/adaptive equipment, participating in weight management with others).

Conclusions:

Healthcare providers identified individual-level, socio-environmental, and organizational barriers and facilitators that influence weight management efforts in individuals with SCI. Future weight management resources and programs should consider addressing common barriers identified by healthcare providers, individuals with SCI, and their caregivers, and develop strategies to promote facilitators to enhance weight management in this population.

Pulsed Electromagnetic Fields Ameliorate Skeletal Deterioration in Bone Mass, Microarchitecture, and Strength by Enhancing Canonical Wnt Signaling-Mediated Bone Formation in Rats with Spinal Cord Injury

Spinal cord injury (SCI) leads to extensive bone loss and high incidence of low-energy fractures. Pulsed electromagnetic fields (PEMF) treatment, as a non-invasive biophysical technique, has proven to be efficient in promoting osteogenesis. The potential osteoprotective effect and mechanism of PEMF on SCI-related bone deterioration, however, remain unknown. The spinal cord of rats was transected at vertebral level T12 to induce SCI. Thirty rats were assigned to the control, SCI, and SCI+PEMF groups (n = 10). One week after surgery, the SCI+PEMF rats were subjected to PEMF (2.0 mT, 15 Hz, 2 h/day) for eight weeks. Micro-computed tomography results showed that PEMF significantly ameliorated trabecular and cortical bone microarchitecture deterioration induced by SCI. Three-point bending and nanoindentation assays revealed that PEMF significantly improved bone mechanical properties in SCI rats. Serum biomarker and bone histomorphometric analyses demonstrated that PEMF enhanced bone formation, as evidenced by significant increase in serum osteocalcin and P1NP, mineral apposition rate, and osteoblast number on bone surface. The PEMF had no impact, however, on serum bone-resorbing cytokines (TRACP 5b and CTX-1) or osteoclast number on bone surface. The PEMF also attenuated SCI-induced negative changes in osteocyte morphology and osteocyte survival. Moreover, PEMF significantly increased skeletal expression of canonical Wnt ligands (Wnt1 and Wnt10b) and stimulated their downstream p-GSK3β and β-catenin expression in SCI rats. This study demonstrates that PEMF can mitigate the detrimental consequence of SCI on bone quantity/quality, which might be associated with canonical Wnt signaling-mediated bone formation, and reveals that PEMF may be a promising biophysical approach for resisting osteopenia/osteoporosis after SCI in clinics.

Barriers and Facilitators to Lifestyle Intervention Engagement and Weight Loss in People Living With Spinal Cord Injury

Background: Individuals living with spinal cord injury (SCI) have a high prevalence of obesity and unique barriers to healthy lifestyle. Objective: To examine barriers and facilitators to engagement and weight loss among SCI participants enrolled in the Group Lifestyle Balance Adapted for individuals with Impaired Mobility (GLB-AIM), a 12-month intensive lifestyle intervention. Methods: SCI participants (N = 31) enrolled in a wait-list, randomized controlled trial where all participants received intervention between August 2015 and February 2017. Analyses of pooled data occurred in 2020 to examine cross-sectional and prospective associations of hypothesized barriers and facilitators with (1) intervention engagement, comprised of attendance and self-monitoring, and (2) percent weight change from baseline to 12 months. We performed multivariable linear regression on variables associated with outcomes at p < .05 in bivariate analyses and controlled for intervention group. Results: Participants were middle-aged (mean age, 48.26 ± 11.01 years), equally male (50%) and female, White (80.7%), and unemployed (65.6%). In participants who completed baseline surveys (n = 30), dietary self-efficacy explained 26% of variance in engagement (p < .01); among the 12-month study completers (n = 22, 71.0%), relationship issues explained 23% of variance in engagement (p < .01). Money problems, health issues unrelated to SCI, lack of motivation, and experimental group explained 57% of variance in weight loss (p for model < .01), with lack of motivation uniquely explaining 24% of variance (p < .01). Conclusion: Improving engagement and weight loss for persons with SCI in the GLBAIM program may be achieved by addressing lack of motivation, relationship issues, and nutrition self-efficacy.
