Falls, mobility, and physical activity after spinal cord injury: an exploratory study using photo-elicitation interviewing

The experience of falls and fall risk during the subacute phase of spinal cord injury: a mixed methods study

PURPOSE

To understand the circumstances, causes and consequences of falls experienced by individuals with subacute SCI, and to explore their perspectives on how falls/fall risk impacted their transition to community living.

MATERIALS AND METHODS

Sixty adults with subacute SCI participated. A sequential explanatory mixed methods design was adopted. In Phase I, falls were monitored for six months post-inpatient rehabilitation discharge through a survey. In Phase II, a qualitative focus group (n = 5) was held to discuss participants' perspectives on Phase I results and falls/fall risk. Descriptive statistics and thematic analysis were used to analyze Phase I and II data, respectively.

RESULTS

Falls commonly occurred in the daytime, at home and about half resulted in minor injury. Three themes reflecting participants' perspectives were identified in Phase II. 1) Lack of preparedness to manage fall risk upon returning home from inpatient rehabilitation. 2) Adjusting to increased fall risk following discharge from inpatient rehabilitation. 3) Psychological impact of the transition to living at home with an increased fall risk.

CONCLUSIONS

The findings highlight the need for fall prevention initiatives during subacute SCI, when individuals are learning to manage their increased fall risk.

"Be ready to learn": a qualitative study of the patient perspective of falls and fall prevention following discharge from a spinal injuries unit

PURPOSE

Falls following a spinal cord injury (SCI) can have physical and psychological consequences, although some risk of falls may be acceptable to enable participation in meaningful activity. The study aimed to explore the patients' perspective of falls and fall prevention after discharge from a inpatient spinal injuries unit.

METHODS

An interpretive descriptive approach guided the study. Semi structured interviews were conducted in the 6-12 months post discharge period. Thematic analysis was used to analyze the data and identify themes.

RESULTS

Fifteen individuals with SCI, with a mean age of 57 years and varied fall experiences were included. Three themes were identified including: 1. Expectation of falling; 2. Learning from my own experience and the experience of others' and 3. How to prevent falls. Learning from their own experience and the experience of others was highly valued by persons with SCI and influenced expectations of falls. A variety of strategies were used to prevent falls.

CONCLUSIONS

Strategies that include learning from others, include activities that are individual and provide skills in self-reflection may aid to make fall prevention meaningful.

A mixed-methods study examining perceptions of fear of falling among community-dwelling people who use wheelchairs full-time

Objective: There is growing evidence that fear of falling (FOF) is common in people who use wheelchairs full-time and negatively influence their performance of daily activities and quality of life. The purpose of this study was to gain an in-depth understanding of perceptions related to FOF among people who use wheelchairs full-time.Methods: Mixed-method analysis was conducted using semi-structured interviews and surveys to gain insight into FOF. Surveys included demographic information; Spinal Cord Injury-Fall Concerns Scale (SCI-FCS); a questionnaire that directly assesses FOF and associated activity curtailment; and Fall Control Scale (FCS).Results: Among 39 participants (age = 43.1 ± 15.6 years, disability duration = 21.2 ± 11.1 years), 27 participants (69%) reported FOF. Participants with less perceived ability to control falls indexed by FCS reported higher SCI-FCS scores, indicating greater FOF (rs = -0.384, p = 0.016). Qualitative findings revealed that participants felt that FOF developed due to sustaining fall-related injuries or limited ability to recover from a fall. Some participants perceived falling as a part of their lives. They believed that it was not the cause of developing FOF.Conclusions: Among people who use wheelchairs full-time, FOF is prevalent and may develop due to fears of sustaining injuries or being unable to get up after falling. Developing an evidenced-based education protocol aimed at managing falls (e.g., establishing a fall recovery strategy and education on techniques to reduce injury during falls) is needed to minimize FOF people who use wheelchairs full-time.

The relationship between balance control and thigh muscle strength and muscle activity in persons with incomplete spinal cord injury

STUDY DESIGN

Cross-sectional study.

OBJECTIVES

A spinal cord injury (SCI) can compromise the ability to maintain sufficient balance control during activities in an upraised position. The objective of the study was to explore the relationship between balance control and muscle strength and muscle activation in the lower extremities in persons with incomplete SCI (iSCI).

SETTING

Sunnaas Rehabilitation Hospital, Norway.

METHODS

Thirteen men and two women with iSCI and 15 healthy, matched controls were included. Performance of the Berg Balance Scale (BBS) short version (7 items) was used to indicate balance control. Maximal voluntary contraction (MVC) was performed to measure isometric muscle strength in thigh muscles (knee extension/flexion), while surface electromyography (EMG) was measured from M. Vastus Lateralis and M. Biceps Femoris. The relative activation of each muscle during each of the BBS tasks was reported as the percentage of the maximal activation during the MVC (%EMGmax).

RESULTS

The iSCI participants had a significantly lower BBS sum score and up to 40% lower muscle strength in knee- flexion and extension compared to the matched healthy controls. They also exhibited a significantly higher %EMGmax, i.e. a higher muscle activation, during most of the balance tests. Univariate regression analysis revealed a significant association between balance control and mean values of %EMGmax in Biceps Femoris, averaged over the seven BBS tests.

CONCLUSIONS

The participants with iSCI had poorer balance control, reduced thigh muscle strength and a higher relative muscle activation in their thigh muscles, during balance-demanding activities.

Understanding the experiences, needs, and strengths of people with incomplete spinal cord injury who can ambulate

PURPOSE

To identify the experiences, needs, and strengths of people with incomplete spinal cord injury who can ambulate and to explore and discuss potential supports, services, and programs that would best assist them in the community.

MATERIAL AND METHODS

In this qualitative descriptive study, interviews were the primary means of data collection. These were supplemented with descriptive standardized measures of function and life satisfaction. Qualitative data were analyzed thematically.

RESULTS

Twenty-four participants were interviewed, their average age was 55 years and 46% were female. We identified three themes: 'I really couldn't go there', described the physical and social barriers experienced by participants, 'It'd be really nice to let the public know there are people out there like me' expressed the desire for greater social understanding of incomplete spinal cord injury, and 'I just don't quit', displayed the perseverance that participants demonstrated following their injury.

CONCLUSION

Findings indicate service providers to improve the inclusion of ambulatory individuals with incomplete spinal cord injury in their programs. Suggestions include designing programs (community, healthcare, return to work, peer support), environments using the principles of universal design for people with incomplete spinal cord injury who ambulate, and increasing consideration of their perspectives.Implication for rehabilitation:People with incomplete spinal cord injury who can ambulate live with invisible impairments, which are often not acknowledged by family, friends, health professionals, and people with complete spinal cord injuryThey may feel excluded from activities (organized by spinal cord injury associations) that were originally designed for people with complete spinal cord injuryGreater awareness among health professionals, friends, family, and people with complete spinal cord injury of the needs of people with incomplete spinal cord injury who can ambulate is needed to increase their inclusion.

Spatial characteristics of reactive stepping among people living with chronic incomplete spinal cord injury

Objective: Compare the spatial characteristics of reactive stepping between individuals with chronic motor incomplete spinal cord injuries (iSCI) and able-bodied (AB) individuals.Design: Cross sectional.Setting: Lyndhurst Centre.Participants: Twelve individuals with iSCI (3 males, 53.6 ± 15.2 years old) and 11 age- and sex-matched AB individuals (3 males, 54.8 ± 14.0 years old).Interventions: The Lean-and-Release test was used to elicit reactive stepping. A horizontal cable, attached at waist height, was released when 8-12% body weight was supported in a forward lean position. Participants underwent up to 10 Lean-and-Release trials in a session. Kinematic and kinetic data were recorded.Outcome measures: The length, width and height of the first reactive step of each trial were calculated. Standard deviation between trials was calculated to represent the variability in step length, width and height within a participant. Among participants with iSCI, correlation coefficients were used to explore the relationship between step length and width variability and (1) Lean-and-Release test behavioral responses, (2) 3-month fall history, and (3) lower extremity strength.Results: Step length (P = 0.94), width (P = 0.52) and height (P = 0.97), normalized for participant height, did not differ between groups. Participants with iSCI showed greater variability in step length (P = 0.02) and width (P = 0.01), but not height (P = 0.32). No correlation was found between step length or width variability and behavioral responses, 3-month fall history, or lower extremity strength.Conclusions: Individuals with iSCI showed increased variability in length and width of reactive stepping compared to AB individuals, which may contribute to their impaired ability to execute single-step reactive responses.Trial registration: ClinicalTrials.gov identifier: NCT02960178.

Identifying priorities for balance interventions through a participatory co-design approach with end-users

BACKGROUND

Most individuals living with spinal cord injuries/diseases (SCI/D) or stroke experience at least one fall each year; hence, the development of interventions and technologies that target balance control is needed. The purpose of this study was to identify and explore the priorities for balance-focused interventions and technologies from the perspectives of end-users to assist with the design of an intervention that combines functional electrical stimulation (FES) with visual feedback training for standing balance.

METHODS

Two individuals with SCI/D, one individual with stroke, two physical therapists (PT) and one hospital administrator were recruited. Participants attended three focus group meetings that followed a participatory co-design approach. A semi-structured interview guide, developed from the FAME (Feasibility, Appropriateness, Meaningfulness, Effectiveness, Economic Evidence) framework, was used to lead the discussion, querying participants' experiences with balance deficits and interventions, and FES. Meetings were audio-recorded and transcribed verbatim. An iterative and reflexive inductive thematic analysis was applied to the transcripts by three researchers.

RESULTS

Four themes were identified: (1) Balance is meaningful for daily life and rehabilitation. Participants acknowledged various factors influencing balance control and how balance deficits interfered with participation in activities. End-users stressed the importance of continuing to work on one's balance after discharge from hospital-based rehabilitation. (2) Desired characteristics of balance interventions. Participants explained that balance interventions should be tailored to an individual's unique needs and goals, relevant to their lives, balance their safety and risk, and be engaging. (3) Prior experiences with FES to inform future therapeutic use. Participants with stroke or SCI/D described initial apprehension with FES, but experienced numerous benefits that motivated them to continue with FES. Challenges with FES were mentioned, including wires, cost, and time of set up. (4) Potential role of FES in balance interventions. Participants felt that FES would complement balance interventions; however, they had not experienced this combination of therapies previously.

CONCLUSIONS

End-users described how their experiences with balance deficits, rehabilitation, and FES informed their priorities for balance interventions. The findings inform the design and implementation of future balance interventions for individuals with SCI/D or stroke, including an intervention involving FES and visual feedback training.

Protocol for a single group, mixed methods study investigating the efficacy of photovoice to improve self-efficacy related to balance and falls for spinal cord injury

INTRODUCTION

Many individuals living with spinal cord injury (SCI) experience falls and a fear of falling, both of which can impact participation in daily activities and quality of life. A single group, convergent mixed methods study will be conducted to examine the effects of a photovoice intervention on falls self-efficacy among individuals living with chronic SCI. Secondary objectives include examining the effects of photovoice on fear of falling, participation and quality of life and exploring participants' experiences and perceptions of the photovoice intervention through qualitative interviews.

METHODS AND ANALYSIS

Adults with SCI (n=40) will be divided into groups according to their mobility status (ie, those who ambulate and those who primarily use a wheelchair). The study will be conducted virtually over three consecutive phases, totalling 30 weeks. Each group will self-report falls for 12 weeks prior to and following the intervention (phases 1 and 3, respectively). The 6-week photovoice intervention (phase 2) will be comprised of two photo assignments, two individual interviews with a researcher and a peer mentor, and four group meetings. Participants will discuss these photos at the interviews and group meetings. Standardised questionnaires of falls self-efficacy, fear of falling, participation and life satisfaction will be administered at four time points (ie, beginning of each phase and the end of phase 3). Questionnaire scores will be examined over time using repeated-measures analysis of variance. A semistructured interview will be completed at the end of phase 3 to gain feedback on the photovoice intervention. Qualitative data will be analysed using reflexive thematic analysis.

ETHICS AND DISSEMINATION

Ethics approval was obtained prior to study enrolment. Findings will be shared through peer-reviewed scientific publications and participant-directed knowledge translation activities.

TRIAL REGISTRATION NUMBER

NCT04864262.

A qualitative photo-elicitation study exploring the impact of falls and fall risk on individuals with subacute spinal cord injury

Background

Individuals living with chronic spinal cord injury or disease (SCI/D) are at an increased risk of falling. However, little is known about the impact of falls and fall risk in the subacute phase of SCI/D, despite this being a time when fall prevention initiatives are delivered. Hence, we explored the impact of falls and fall risk in individuals with subacute SCI/D as they transitioned from inpatient rehabilitation to community living.

Methods

This qualitative photo-elicitation study used an inductive thematic analysis. Eight individuals (7 male) undergoing inpatient rehabilitation at a Canadian tertiary rehabilitation hospital due to a new SCI/D participated. Six months following discharge, photo-elicitation interviewing was used to understand the impact of falls and fall risk. Over 7–14 days, participants completed a photo-assignment that involved taking photographs in response to questions, such as what increases/decreases your likelihood of falling? A semi-structured interview followed, in which participants described their photographs and discussed their experiences with falls, fall risk and fall prevention training.

Results

Four themes were identified. 1) Risk factors and strategies identified through lived experience. Participants discovered their fall risk factors and fall prevention strategies through “trial and error”. 2) Influences on the individual’s perception of their fall risk. Prior experience with falls, including falls experienced by themselves as well as friends and family, influenced their perception of fall risk. 3) Experiencing life differently due to increased fall risk. A high fall risk reduced participation, increased negative emotions and decreased independence and quality of life. 4) Falls training in rehabilitation can be improved. Prior experiences with falls training varied; however, participants expressed a desire for comprehensive and individualized training.

Conclusion

Although participants’ experiences with falls and fall prevention varied, falls and the risk of falling can have a significant impact on the first year of living with a SCI/D.

The impact of falls and fear of falling on participation, autonomy, and life satisfaction among individuals with spinal cord injury: A brief report

CONTEXT

Qualitative research suggests that falls can have a negative psychosocial impact on the lives of individuals with spinal cord injury (SCI). However, it is unclear whether these qualitative findings are supported by quantitative psychosocial metrics. This paper examines whether falling and/or having a fear of falling impacts participation, autonomy, and life satisfaction among individuals with SCI.

METHODS

Falls and fear of falling were tracked over six months using a survey and phone check-ins conducted approximately every three to four weeks. The Life Satisfaction 9 and Impact on Participation and Autonomy Questionnaires were administered at baseline and after six months. Responses on the questionnaires were statistically compared between fallers and non-fallers as well as participants with and without a fear of falling during the tracking period.

FINDINGS

Of the 65 community-dwelling adults with chronic SCI, 38 were categorized as fallers (aged 54.29 ± 13.73, 19.55 ± 14.20 years post-SCI, AIS A-D) and 27 were non-fallers (aged 57.78 ± 12.21, 17.93 ± 17.24 years post-SCI, AIS A-D). Our results revealed no significant differences between fallers and non-fallers in their perceived participation, autonomy, or life satisfaction at baseline or after six months. At the last check-in, 34 participants denied a fear of falling, while 31 had a fear of falling. Perceived autonomy outdoors (P=0.02), total life satisfaction (P=0.04), satisfaction with life as a whole (P=0.00) and self-care (P=0.01) differed between participants with and without a fear of falling after six months.

CONCLUSION

Fear of falling, rather than falls, may impact participation, autonomy, and life satisfaction in the SCI population.

Falls Occurring After a Spinal Cord Injury: A Scoping Review

IMPORTANCE

Falls have a considerable physical and psychological impact on people with spinal cord injury (SCI). Occupational therapy practitioners require evidence to support the timely development of occupation-based programs that can be applied to fall prevention in daily life.

OBJECTIVE

To determine what is known about falls after SCI, including wheelchair users and people who are ambulatory, and to understand elements of fall prevention to be addressed by occupational therapy practitioners. We applied the Canadian Measure of Occupational Performance and Engagement to understand elements to be addressed in fall education and prevention with this population.

DATA SOURCES

We searched eight databases using the key words falls and spinal cord injury with no limit set on dates. Study Selection and Data Collection: Studies were included that reported on falls among adults with SCI and measured one or more of the following: incidence of falls, consequences of falls, contributing factors for falls, the person's experience of falls, and strategies to prevent falls.

FINDINGS

Thirty-five articles were included. The majority of the articles included information on the incidence (n = 20), consequences (n = 26), and contributing factors (n = 30) of falls. Two articles analyzed the person's experience of falls, and 1 study reviewed a fall prevention program for people with SCI specifically.

CONCLUSIONS AND RELEVANCE

Research on participants' experience of falls and fall prevention programs used in spinal cord rehabilitation is extremely limited. Future research on the lived experience of falls for people with SCI is warranted. What This Article Adds: This review of evidence on falls after SCI highlights gaps in the current available evidence.

Therapists' perspectives on fall prevention in spinal cord injury rehabilitation: a qualitative study

PURPOSE

Therapists play a key role in delivering fall prevention/management education to individuals with spinal cord injury/disease, yet their perspectives on this topic remain understudied. Here, we described the perspectives of physical and occupational therapists who routinely provided rehabilitation to patients with spinal cord injury/disease on: (1) how fall risk was assessed, (2) what fall prevention education, interventions or strategies were provided, and (3) opportunities to improve fall risk assessment and the delivery of fall prevention education, strategies and interventions.

MATERIALS AND METHODS

Twenty-one therapists completed an individual interview or focus group that was analyzed using an inductive thematic analysis.

RESULTS

Four main themes were identified: (1) policy and procedures impact practice (i.e., policy and procedures positively and negatively impact practice), (2) assessing and managing fall risk/falls in patients with spinal cord injury/disease (i.e., discipline-specific roles in fall risk assessments and fall management processes in rehabilitation), (3) fall prevention and management education (i.e., helicopter therapists and challenges with fall prevention and management education), (4) building insight into fall risk and management (e.g., building insight into fall risk for patients and therapists).

CONCLUSIONS

This study revealed opportunities to improve the delivery of fall prevention education and training to individuals with spinal cord injury/disease.IMPLICATIONS FOR REHABILITATIONFall prevention education should be initiated in spinal cord injury rehabilitation and then reinforced in community rehabilitation.Barriers and challenges faced by therapists when delivering fall prevention and management education/training in spinal cord injury rehabilitation include their perceptions of a patient's readiness to receive fall prevention education, short length of stay in rehabilitation, organization's expectations of zero falls and a lack of spinal cord injury-specific fall prevention resources.Therapists who work in spinal cord injury rehabilitation may benefit from information about fall risk factors encountered by individuals with spinal cord injury/disease in the community.

Investigating proactive balance control in individuals with incomplete spinal cord injury while walking on a known slippery surface

BACKGROUND

Up to 83 % of individuals with incomplete spinal cord injury (iSCI) experience ≥ 1 fall/year. Individuals with iSCI employ more cautious walking strategies than able-bodied (AB) individuals during normal walking. Whether individuals with iSCI can use proactive balance strategies to adapt to expected slip perturbations/reduce slip severity while walking has not been previously assessed.

METHODS

19 individuals with iSCI (AIS D; 14 males; 61 ± 18 years) and 17 AB individuals (13 males; 61 ± 18 years) completed 3 walking conditions: normal walking trials, an unexpected slip trial, and expected slip trials. Steel rollers induced a slip in the antero-posterior (AP) direction. Outcome variables included step length, center of mass velocity, foot-floor angle, AP margin of stability, and maximum post-slip velocity (PSV).

RESULTS

The iSCI group used a greater magnitude of cautious strategies (i.e. walking slower with shorter, flatter steps) than AB individuals in all conditions. However, the lack of significant interaction effects indicate that the proactive adaptations compared to normal walking (i.e. walking slower with shorter, flatter steps, and a more anterior xCOM-position) were similar between the two groups (AB & iSCI). Both groups showed a similar rate of adaptation (after just 1 slip) and these feedforward changes were maintained throughout the remaining slip trials which was effective at reducing maximum PSV.

CONCLUSIONS

Individuals with iSCI use proactive balance strategies to adapt to a known slippery surface in a similar manner to AB individuals both in terms of the proportion and timing of adaptation.

The Effect of Perturbation-Based Balance Training and Conventional Intensive Balance Training on Reactive Stepping Ability in Individuals With Incomplete Spinal Cord Injury or Disease: A Randomized Clinical Trial

Introduction: Impaired balance leads to falls in individuals with motor incomplete spinal cord injury or disease (iSCI/D). Reactive stepping is a strategy used to prevent falls and Perturbation-based Balance Training (PBT) can improve this ability.

Objective: The objective of this study was to determine if PBT results in greater improvements in reactive stepping ability than frequency-matched Conventional Intensive Balance Training (CIBT) in adults with iSCI/D.

Design: Randomized clinical trial.

Setting: Tertiary SCI/D rehabilitation center.

Participants: Twenty-one adults with chronic (>1 year) iSCI/D were randomized. Due to one drop out 20 participants completed the study.

Methods: Participants were randomly allocated to complete either PBT or CIBT three times per week for 8 weeks. Both programs included challenging static and dynamic balance tasks, but the PBT group also experienced manual external balance perturbations.

Main Outcome Measures: Assessments of reactive stepping ability using the Lean-and-Release test were completed at baseline, and after 4 and 8 weeks of training, and 3 and 6 months after training completion. A blinded assessor evaluated secondary outcomes.

Results: Twenty-five participants were screened and 21 consented; one withdrew. Ten PBT and 10 CIBT participants were included in analyses. Across all participants there were improvements in reactive stepping ability (p = 0.049), with retention of improvements at follow up assessments. There were no differences in reactive stepping ability between groups [median (interquartile range): PBT 0.08 (0.68); CIBT 0.00 (0.22)]. One participant in the PBT group experienced a non-injurious fall during training.

Conclusions: Balance training is beneficial for individuals with iSCI/D, but the addition of manual perturbations (i.e., PBT) did not prove advantageous for performance on a measure of reactive stepping ability.

Comparing the causes, circumstances and consequences of falls across mobility statuses among individuals with spinal cord injury: A secondary analysis

OBJECTIVE

To compare the occurrence of falls and fall-related injuries, and the circumstances of falls among individuals with spinal cord injury (SCI) who ambulate full-time, use a wheelchair full-time and ambulate part-time.

DESIGN

A secondary analysis.

SETTING

Community.

PARTICIPANTS

Adults with SCI.

INTERVENTION

None.

OUTCOME MEASURES

The occurrence and circumstances of falls and fall-related injuries were tracked over six-months using a survey. Participants were grouped by mobility and fall status. A chi-square test compared the occurrence of falls and fall-related injuries, and the time and location of falls, and a negative binomial regression was used to predict the likelihood of falls by mobility status. Kaplan-Meier analysis was used to determine differences in the time to first fall based on mobility status. Group characteristics and causes of falls were described.

RESULTS

Data from individuals who ambulated full-time (n = 30), used a wheelchair full-time (n = 27) and ambulated part-time (n = 8) were analyzed. Mobility status was a significant predictor of falls (P < 0.01); individuals who used a wheelchair full-time had a third of the likelihood of falling than those who ambulated full-time (P < 0.01). Type of fall-related injuries differed by mobility status. Those who ambulated full-time fell more in the daytime (P < 0.01). Individuals who ambulated full-time and part-time commonly fell while walking due to poor balance, and their legs giving out, respectively. Those who used a wheelchair full-time typically fell while transferring when rushed.

CONCLUSION

Mobility status influences the likelihood and circumstances of falls. Mobility status should be considered when planning fall prevention education/training for individuals with SCI.

Evaluating Intrinsic Fall Risk Factors After Incomplete Spinal Cord Injury: Distinguishing Fallers From Nonfallers

Objective

To determine whether performance on measures of lower extremity muscle strength, sensory function, postural control, gait speed, and balance self-efficacy could distinguish fallers from nonfallers among ambulatory individuals with spinal cord injury or disease (SCI/D).

Design

Prospective cohort study.

Setting

Community.

Participants

Individuals (N=26; 6 female, aged 58.9±18.2y) with motor incomplete SCI/D (American Spinal Injury Association Impairment Scale rating C [n=5] or D [n=21]) participated. Participants were 7.5±9.1 years post injury. Seventeen participants experienced traumatic causes of spinal cord injury.

Main Outcome Measures

Participants completed laboratory-based and clinical measures of postural control, gait speed, balance self-efficacy, and lower extremity strength, as well as proprioception and cutaneous pressure sensitivity. Participants were then followed for up to 1 year to track falls using a survey. The survey queried the circumstances and consequences of each fall. If a participant's number of falls equaled or exceeded the median number of falls experience by all participants, they were classified a faller.

Results

Median follow-up duration was 362 days and median time to first fall was 60.5 days. Fifteen participants were classified as fallers. Most falls occurred during the morning or afternoon (81%), at home (75%), and while walking (47%). The following laboratory-based and clinical measures distinguished fallers from nonfallers (P<.05): measures of lower extremity strength, cutaneous pressure sensitivity, walking speed, and center of pressure velocity in the mediolateral direction.

Conclusions

There are laboratory-based and clinical measures that can prospectively distinguish fallers from nonfallers among ambulatory individuals with spinal cord injury. These findings may assist clinicians when evaluating their patients' fall risk.

Exploring the causes and impacts of falls among ambulators with spinal cord injury using photovoice: a mixed-methods study

OBJECTIVES

This study explored: (1) fall circumstances experienced by ambulators with spinal cord injury (SCI) over a 6-month period, (2) the impacts of falls-related injuries and fall risk and (3) their preferences/recommendations for fall prevention.

DESIGN

A sequential explanatory mixed-methods design with two phases.

SETTING

A Canadian SCI rehabilitation hospital and community setting.

PARTICIPANTS

Thirty-three ambulators with SCI participated in phase 1 and eight participants that fell in phase 1 participated in phase 2.

METHODS

In phase 1, fall circumstances were tracked using a survey that was completed each time a participant fell during the 6-month tracking period. Phase 2 involved photovoice; participants took photographs of factors that influenced their fall risk and how their fall risk impacted their work/recreational activities. Participants discussed the photographs and topics related to fall prevention in an individual interview and a focus group.

RESULTS

Of the 33 participants, 21 fell in 6 months. Falls commonly occurred in the home while participants were changing positions or walking. Most falls occurred in the morning or afternoon. In phase 2, interviews and focus group discussion revealed three themes: (1) falls are caused by bodily impairments (eg, impaired reactive response during slips and trips and weakness and altered sensation in legs/feet), (2) impacts of fall-related injuries and fall risk (eg, psychosocial effects of fall-related injuries, limiting community participation due to the risk of falling and activity-dependent concern of falling) and (3) approaches to fall prevention (eg, fall prevention strategies used, components of fall prevention and utility of professional fall prevention strategies/interventions).

CONCLUSIONS

Fall prevention interventions/strategies should focus on minimising a person's fall risk within their home as most falls occurred in the home environment. Ambulators with SCI would benefit from education and awareness about common fall circumstances that they may encounter in their daily lives.

Perspectives of wheelchair users with spinal cord injury on fall circumstances and fall prevention: A mixed methods approach using photovoice

Introduction

Wheelchair users with spinal cord injury are at a high risk of falls. However, the perspectives of wheelchair users with spinal cord injury on their fall circumstances and their preferences for fall prevention strategies/interventions remain understudied. Therefore, we aimed to: a) describe the circumstances of falls experienced by wheelchair users with spinal cord injury over a six-month period, b) explore their perspectives of why falls occurred in certain situations, and c) explore their perspectives on recommended content/structure of fall prevention strategies/interventions.

Methods

This sequential explanatory mixed methods study had two phases. Phase I involved tracking of falls experienced by wheelchair users with spinal cord injury over six months, in which participants completed a survey after experiencing a fall to track the number/circumstance of each fall. Data from the surveys were descriptively reported. Phase II involved a photovoice focus group discussion of the survey findings and their preferences for fall prevention strategies/interventions. Data from the focus group discussion were analyzed using a thematic analysis.

Results

Thirty-two participants completed phase I. More than half of the participants fell at least once in six months. Falls commonly occurred in the afternoon during a transfer, or when participants were wheeling over uneven ground. One-third of the falls caused an injury. Eleven participants that fell during phase I participated in the focus group. Two main themes were identified from the discussion: 1) “circumstances surrounding the falls” (e.g. when falls occurred, the home is a ‘safe space’) and 2) “suggestions and preferences for fall prevention strategies/interventions” (e.g. fall prevention involves all, fall prevention training available as needed).

Conclusion

Fall prevention strategies/interventions should be an integral component of rehabilitation practices across the lifespan. Participants recommend customizing fall prevention strategies/interventions to their specific needs to guide the structure, content, and delivery of targeted fall prevention programs.

Functional Electrical Stimulation Plus Visual Feedback Balance Training for Standing Balance Performance Among Individuals With Incomplete Spinal Cord Injury: A Case Series

Individuals with an incomplete spinal cord injury (iSCI) are highly susceptible to falls during walking or standing. Our objective was to evaluate a therapeutic tool for standing balance that combined functional electrical stimulation, applied bilaterally to the plantarflexors and dorsiflexors, with visual feedback balance training (FES+VFBT). Five adults with iSCI completed 12 FES+VFBT sessions over 4 weeks. During the training sessions, participants completed each of the four balance exercises twice. Visual feedback of the center-of-pressure (COP) location was provided as participants completed the balance exercises and received FES to assist with performance of the exercises. A closed-loop FES system was used in which the COP was continually monitored and the level of electrical current administered was automatically adjusted. Balance abilities were assessed pre- and post- training using clinical balance scales (i.e., Berg Balance Scale, Mini-Balance Evaluation Systems Test, and Activities-specific Balance Confidence Scale) and biomechanical assessments (i.e., postural sway measures and limits of stability test during standing). User acceptability was explored through semi-structured interviews. Improvements were seen for four of the five participants on at least one of the clinical scales following completion of the training intervention. All participants showed greater maximal COP excursion area during the limits of stability test after the training intervention, whereas only one participant demonstrated a reduction in postural sway. Specific components of FES+VFBT, including the ability to safely practice challenging balance exercises, were deemed important by the participants. These results suggest that FES+VFBT has potential as an intervention for standing balance after iSCI.

The effects of light touch on gait and dynamic balance during normal and tandem walking in individuals with an incomplete spinal cord injury

STUDY DESIGN

Prospective cross-sectional study OBJECTIVES: To investigate the effect of adding haptic input during walking in individuals with incomplete spinal cord injury (iSCI).

SETTING

Research laboratory.

METHODS

Participants with iSCI and age- and sex-matched able-bodied (AB) individuals walked normally (SCI n = 18, AB n = 17) and in tandem (SCI n = 12, AB n = 17). Haptic input was added through light touch on a railing. Step parameters, and mediolateral and anterior-posterior margins of stability (means and standard deviations) were calculated. Surface electromyography data were collected bilaterally from the tibialis anterior (TA), soleus (SOL), and gluteus medius (GMED) and integrated over a stride. Repeated measures ANOVAs examined within- and between-group differences (α = 0.05). Cutaneous and proprioceptive sensation of individuals with iSCI were correlated to changes in outcome measures that were affected by haptic input.

RESULTS

When walking normally, adding haptic input decreased stride velocity, step width, stride length, MOS_ML, MOS_ML_SD, MOS_AP, and MOS_AP_SD, and increased GMED activity on the limb opposite the railing. During tandem walking, haptic input had no effect; however, individuals with iSCI had a larger step width SD and MOS_ML_SD compared with the AB group. Sensory abilities of individuals with iSCI were not correlated to any of the outcome measures that significantly changed with added haptic input.

CONCLUSIONS

Added haptic input improved balance control during normal but not in tandem walking. Sensory abilities did not impact the use of added haptic input during walking.

Current state of fall prevention and management policies and procedures in Canadian spinal cord injury rehabilitation

Background

Preventing patient falls is a priority in tertiary spinal cord injury (SCI) rehabilitation. Falls can result in patient or staff injury, delayed rehabilitation, and hospital liability. A comprehensive overview of fall prevention/management policies and procedures in Canadian SCI rehabilitation is currently lacking. We describe and compare the fall prevention/management policies and procedures implemented in Canadian tertiary hospitals that provide SCI rehabilitation.

Methods

Fall prevention/management documents implemented in SCI rehabilitation at six Canadian tertiary rehabilitation hospitals across five provinces were analyzed using a document analysis. Analysis involved multiple readings of the documents followed by a content and thematic document analysis.

Results

Fall prevention/management policies and procedures in SCI rehabilitation were organized into three main categories: 1) pre-fall policies and procedures; 2) post-fall policies and procedures; and, 3) communication between and amongst staff, patients, and families. Pre-fall policies and procedures encompassed: a) the definition of a fall; b) fall risk assessments in SCI rehabilitation; and, c) fall prevention strategies. The post-fall policies and procedures included: a) recovery from a fall; b) incident reporting process; and, c) fall classification. Components of fall prevention/management policies and practices that differed between hospitals included the fall risk assessments, post-fall huddles, and fall classifications.

Conclusions

Fall prevention/management is a required organizational practice for all hospitals. Although Canadian tertiary hospitals that provide SCI rehabilitation have similar components of fall prevention/management policies and procedures, the specific requirements differ at each site. There is a need for evidence-informed, consensus-driven implementation of SCI-specific fall prevention and management procedures across Canadian SCI rehabilitation settings.

Factors that influence the risk of falling after spinal cord injury: a qualitative photo-elicitation study with individuals that use a wheelchair as their primary means of mobility

INTRODUCTION

Falls are a concern for wheelchair users with spinal cord injury (SCI). Falls can negatively impact the physical and psychological well-being of fallers. To date, the perspectives of wheelchair users with lived experiences of SCI on the contributors to falls has been understudied. Information about factors that influence fall risk would guide the development of effective fall prevention strategies.

OBJECTIVES

To gain a comprehensive understanding of the factors that influenced the risk of falling as perceived by wheelchair users with SCI.

DESIGN

A qualitative study using photo-elicitation interviews.

SETTING

A Canadian SCI rehabilitation hospital and the participants' home/community environments.

PARTICIPANTS

Twelve wheelchair users living in the community with chronic SCI.

METHODS

Participants captured photographs of situations, places or things that they perceived increased and decreased their risk of falling. Semistructured photo-elicitation interviews were conducted to discuss the content of the photographs and explore perceptions of fall risk factors. A hybrid thematic analysis and the Biological, Behavioural, Social, Economic, and Environmental model were used as a framework to organise/synthesise the data.

RESULTS

Overall, the findings indicated that the risk of falling was individualised, complex and dynamic to each person's life situation. Four main themes were revealed in our analysis: (1) Falls and fall risk caused by multiple interacting factors; (2) Dynamic nature of fall risk; (3) Single factors were targeted to reduce falls and fall-related injuries; and (4) Fall prevention experiences and priorities.

CONCLUSIONS

Each wheelchair user encountered numerous fall risk factors in their everyday lives. Information from this study can be used to set priorities for fall prevention. Fall prevention initiatives should consider a wheelchair user's fall risks in a holistic manner, acknowledging that a person's current situation, as well as anticipating their fall risks and fall prevention needs, will change over time.

Quantifying balance control after spinal cord injury: Reliability and validity of the mini-BESTest

Context/Objective: Incomplete spinal cord injury (iSCI) causes deficits in balance control. The Mini-Balance Evaluation Systems Test (mini-BESTest) is a comprehensive measure; however, further testing of its psychometric properties among the iSCI population is needed. We evaluated the mini-BESTest's test-retest reliability, and concurrent and convergent validity among individuals living with iSCI for more than one year. Design: Cross-sectional study. Setting: Rehabilitation hospital. Participants: Twenty-one individuals with chronic motor iSCI (14 females, mean age 56.8 ± 14.0 years). Interventions: None. Outcome Measures: Participants completed the mini-BESTest at two sessions spaced two weeks apart. At the second session, participants performed tests of lower extremity muscle strength and quiet standing on a force platform with eyes opened (EO) and eyes closed (EC). Intraclass correlation coefficients (ICC) evaluated test-retest reliability. To evaluate concurrent and convergent validity, Pearson's correlation coefficient (r) quantified relationships between mini-BESTest scores and measures of center of pressure (COP) velocity during EO and EC standing, and lower extremity muscle strength, respectively. Results: Test-retest reliability of the mini-BESTest total score and sub-scale scores were high (ICC = 0.94-0.98). Mini-BESTest scores were inversely correlated with COP velocity when standing with EO (r = 0.54-0.71, P < 0.05), but not with EC. Lower extremity strength correlated strongly with mini-BESTest total scores (r = 0.73, P < 0.001). Conclusion: The mini-BESTest has high test-retest reliability, and concurrent and convergent validity in individuals with chronic iSCI.

Do clinical balance measures have the ability to predict falls among ambulatory individuals with spinal cord injury? A systematic review and meta-analysis

STUDY DESIGN

Systematic review and meta-analysis.

BACKGROUND AND PURPOSE

Fall prevalence is high among individuals with spinal cord injury (SCI) and falls may lead to serious consequences. The objective of this study was to investigate the ability of clinical balance measures to predict falls among ambulatory individuals with SCI.

METHODS

We searched the online databases MEDLINE, Web of Science, Scopus, SportDiscuss, and CINAHL. Two reviewers independently selected prospective and cross-sectional studies of ambulatory adults with SCI, with a method of falls tracking and a clinical balance evaluation. Risk of bias was assessed using the Newcastle-Ottawa Quality Assessment Scale. A meta-analysis of prospective and cross-sectional studies was performed using Review Manager 5.3.

RESULTS

Ten studies from the 2672 studies identified were included in the qualitative synthesis. Nine studies were included in the meta-analyses. The Berg Balance Scale (BBS) and the Timed Up and Go Test demonstrate ability to differentiate between fallers and non-fallers, mean difference 5.25 (95% CI, 0.29 to 10.20) and 6.65 (95% CI, 0.17 to 13.12) respectively. The BBS presents moderate predictive ability (area under the receiver operating characteristic curve of 0.61 and sensitivity of 65%). Individuals with a BBS score ≥ 40 are likely at risk of falls.

CONCLUSION

The BBS is the most appropriate and specific clinical balance measure with the ability to discriminate between ambulatory fallers and non-fallers. However, the fall predictive abilities of the measure need to be further explored and improved for this population.

Falls after spinal cord injury: a systematic review and meta-analysis of incidence proportion and contributing factors

INTRODUCTION

Falls are detrimental to the well-being of individuals with spinal cord injury (SCI). To establish effective fall prevention initiatives, a comprehensive understanding of falls after SCI is needed.

OBJECTIVES

To report the incidence proportion of falls and summarize the factors contributing to falls in individuals with SCI.

STUDY DESIGN

Systematic review and meta-analysis.

METHODS

Eight databases were searched. Abstracts/full articles were screened by two researchers independently. Data concerning study design, participant characteristics, and the incidence proportion, factors, and consequences of falls were extracted. Risk of bias was assessed using a domain-based approach that considered sampling and measurement bias. The incidence proportions of falls were pooled for ambulators and wheelchair users separately using random-effects meta-analyses, and compared descriptively for inpatients and community-dwelling individuals. Fall-related factors were organized according to the Biological, Behavioral, Social & Economic and Environmental Model of fall risk.

RESULTS

The search resulted in 1706 articles; 24 unique studies were included. The risk of sampling bias was high. All but one study focused on community-dwelling individuals; 78% (95% confidence interval 73-83%, I² = 0%) of ambulators and 69% (95% confidence interval 60-76%, I² = 59%) of wheelchair users fell ≥1 over 12 months. In contrast, only 13% of inpatients fell. Most fall-related factors were categorized as biological (e.g., muscle weakness), behavioral (e.g., inattentiveness) or environmental (e.g., uneven surfaces).

CONCLUSIONS

Falls are frequent among community-dwelling individuals with SCI. A variety of biological, behavioral, and environmental factors contribute to falls, some of which are modifiable and may be addressed through SCI-specific fall prevention initiatives.

Current state of balance assessment during transferring, sitting, standing and walking activities for the spinal cord injured population: A systematic review

CONTEXT

Comprehensive balance measures with high clinical utility and sound psychometric properties are needed to inform the rehabilitation of individuals with spinal cord injury (SCI).

OBJECTIVE

To identify the balance measures used in the SCI population, and to evaluate their clinical utility, psychometric properties and comprehensiveness.

METHODS

Medline, PubMed, Embase, Scopus, Web of Science, and the Allied and Complementary Medicine Database were searched from the earliest record to October 19/16. Two researchers independently screened abstracts for articles including a balance measure and adults with SCI. Extracted data included participant characteristics and descriptions of balance measures. Quality was evaluated by considering study design, sampling method and adequacy of description of research participants. Clinical utility of all balance measures was evaluated. Comprehensiveness was evaluated using the modified Systems Framework for Postural Control.

RESULTS

2820 abstracts were returned and 127 articles included. Thirty-one balance measures were identified; 11 evaluated a biomechanical construct and 20 were balance scales. All balance scales had high clinical utility. The Berg Balance Scale and Functional Reach Test were valid and reliable, while the mini-BESTest was the most comprehensive.

CONCLUSION

No single measure had high clinical utility, strong psychometric properties and comprehensiveness. The mini-BESTest and/or Activity-based Balance Level Evaluation may fill this gap with further testing of their psychometric properties.
