Effectiveness of physical rehabilitation for physical functioning and quality of life in long-term care residents with dementia: a systematic review and meta-analysis

OBJECTIVE

The objective of this review was to evaluate the effectiveness of physical rehabilitation vs non-rehabilitation comparators for physical functioning and quality of life in long-term care (LTC) residents with dementia.

INTRODUCTION

LTC residents living with dementia often have impaired physical functioning and quality of life. Physical rehabilitation can improve physical functioning and quality of life for individuals living with dementia; however, many LTC residents with dementia do not receive physical rehabilitation and providers are unsure what interventions to employ. A synthesis of studies examining physical rehabilitation will help guide practice in the LTC sector where most residents live with dementia. Previous syntheses have focused on all residents in LTC, specific professions, interventions, or people with dementia in the community. Our review focused on LTC residents with dementia and used a broader definition of physical rehabilitation.

INCLUSION CRITERIA

This review included studies that evaluated physical rehabilitation in comparison with non-rehabilitation controls among LTC residents with any severity of dementia. We included experimental and quasi-experimental studies that measured the effect on activities of daily living, performance-based physical functioning, and self- or proxy-rated quality of life.

METHODS

Searches were conducted in APA PsycINFO (EBSCOhost), CINAHL (EBSCOhost), PubMed (National Library of Medicine), Embase, Scopus, and the Cochrane CENTRAL database with no date or language limitations. Two independent reviewers assessed the studies against the inclusion criteria. Two independent reviewers extracted data and conducted a methodological quality assessment using standardized checklists from JBI. Certainty of evidence was ascertained using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. Where possible, studies were pooled in meta-analyses; otherwise, a narrative synthesis was presented.

RESULTS

Thirty-three studies were included (n=3072 participants); 27 were randomized controlled trials and (RCTs) the remaining 6 were non-randomized trials. The overall risk of bias of the included studies was low to unclear. Many of the included studies focused on increasing activity or walking, while few were individually tailored or at an intensity appropriate to induce therapeutic effects on physical function. Physical function was measured via several outcome measures, limiting our ability to pool results. There was low-certainty evidence that physical rehabilitation improved activities of daily living assessed with multiple instruments (12 RCTs, 1348 participants, standardized mean difference [SMD] 0.78; 95% CI 0.27 to 1.30) and lower extremity function assessed with the Short Physical Performance Battery Score (3 RCTs, 258 participants, mean difference [MD] 3.01 points; 95% CI 1.37 to 4.66), compared with non-rehabilitation interventions. There was very low- to moderate-certainty evidence that physical rehabilitation demonstrated no change in the 30-Second Sit to Stand Test (2 RCTs, 293 participants, MD 0.79 repetitions; 95% CI -0.45 to 2.03), 6-Minute Walk Test (4 RCTs, 363 participants, MD 17.32 meters; 95% CI -29.41 to 64.05), Timed Walk Test (4 RCTs, 400 participants, MD 0.10 meters/seconds; 95% CI -0.02 to 0.22), Timed Up and Go Test (3 RCTs, 275 participants, MD -2.89 seconds; 95% CI -6.62 to 0.84), or quality of life (4 RCTs, 419 participants, SMD 0.20; 95% CI -0.08 to 0.47).

CONCLUSIONS

This review demonstrates that physical rehabilitation may improve activities of daily living for LTC residents living with dementia, although the evidence is of low certainty. The effect of physical rehabilitation on specific functional tasks, such as gait speed and quality of life, are less clear. Future research should examine the effects of individualized, progressive interventions on outcome measures that reflect the capacity and preferences of LTC residents with more advanced dementia.

High Intensity Functional Training for People with Parkinson's & Their Care Partners: A Feasibility Study

PURPOSE

Various forms of exercise have proven health benefits for people with Parkinson's (pwPD) yet high intensity functional training (HIFT) has yet to be studied. The purpose of this study was to examine the feasibility, physical and psychosocial impacts of a HIFT program for pwPD and their care partners (CPs).

DESIGN

A single group, pre-post design with assessments before, in the middle (13 weeks), and after the 25-week intervention.

SETTING

Community fitness facility.

PARTICIPANTS

Fourteen pwPD (10 at Hoehn Yahr Stage ≤2, 4 females) and 10 CPs (5 females) were included (mean age = 71.5 (6.1)).

INTERVENTION

A 25-week HIFT program (≤49 exercise sessions, ≤75 min long).

MEASURES

Recruitment, retention, attendance, safety and exercise intensity (measured via session-Rating of Perceived Exertion (RPE)) was assessed in addition to cardiovascular endurance, lower extremity strength, walking speed, balance, exercise self-efficacy, balance confidence, social support for exercise and health-related quality of life.

ANALYSIS

Descriptive data was used to describe feasibility measures. Wilcoxon signed-rank test was used to compare pre- and post-program data. Effect size, r, was calculated.

RESULTS

Recruitment rates were ≥40% for pwPD and CPs and retention rates were 80% for pwPD and 62.5% for CPs. Average session attendance was 71.2% with 15 adverse events reported, including 7 non-injurious falls. Median session-RPE was 5 (IQR = 1) out of 10. PwPD demonstrated significant improvements in cardiovascular endurance, self-selected and fast walking speeds, balance and social support for exercise. CPs demonstrated significant improvements in cardiovascular endurance and lower extremity strength. Exercise self-efficacy, balance confidence and health-related quality of life did not significantly change for pwPD or CPs.

CONCLUSION

High intensity functional training appears feasible for pwPD and their CPs and may lead to health benefits. Healthcare providers should consider HIFT as another option to engage pwPD in community-based exercise.

Adherence and potential factors of adherence to a resistance, coordination and endurance training in older retirement home residents over 6 months

INTRODUCTION

High exercise adherence is a key factor for effective exercise programmes. However, little is known about predictors of exercise adherence to a multimodal machine-based training in older retirement home residents.

AIMS

To assess exercise adherence and potential predictors of adherence. Furthermore, to evaluate user acceptance of the multimodal training and the change in exercise self-efficacy.

METHODS

In this sub-analysis of the bestform-F study, a total of 77 retirement home residents ≥65 years (mean age: 85.6 ± 6.6 years, 77.9% female) participated in a 6-month machine-based resistance, coordination and endurance training. Attendance to the training was documented for each training session. To identify potential predictors a multiple linear regression model was fitted to the data. Analyzed predictors included age, sex, body mass index (BMI), physical function, exercise self-efficacy, and physical activity history. Different domains of user acceptance (e.g. safety aspects, infrastructure) and exercise self-efficacy were assessed by a questionnaire and the exercise self-efficacy scale (ESES), respectively.

RESULTS

Mean exercise adherence was 67.2% (median: 74.4%). The regression model (R2  = 0.225, p = 0.033) revealed that the 6-minute walk test (6-MWT) at baseline significantly predicted exercise adherence (β: 0.074, 95% confidence interval (CI): 0.006-0.142, p = 0.033). Different user domains were rated at least as good by 83.9%-96.9% of participants, reflecting high acceptance. No statistically significant change was found for exercise self-efficacy over 6 months (mean change: 0.47 ± 3.08 points, p = 0.156).

CONCLUSION

Retirement home residents attended more than two thirds of offered training sessions and physical function at baseline was the key factor for predicting adherence. User acceptance of the training devices was highly rated. These findings indicate good potential for implementation of the exercise programme.

Study protocol of a cluster-randomised controlled trial assessing a multimodal machine-based exercise training programme in senior care facilities over 6 months - the bestform study (best function of range of motion)

BACKGROUND

Physical functioning is a crucial factor for independence and quality of life in old age. The aim of the "bestform-Best function of range of motion" trial is to investigate the effects of a 6 months multimodal machine-based strength, coordination and endurance training on physical function, risk of falls and health parameters in older adults.

METHODS

Bestform is a cluster-randomised trial including older adults  ≥ 65 years living in senior care facilities in Southern Germany. Senior care facilities are randomly allocated to the control group with usual care (n ≥ 10 care facilities) and to the intervention group (n ≥ 10 care facilities), overall including  ≥ 400 seniors. Residents belonging to the intervention group are offered a supervised machine-based exercise training programme twice weekly over 45-60 min over six months in small groups, while those in the usual care facilities will not receive active intervention. The primary outcome is the change in Short Physical Performance Battery over six months between groups. Secondary outcomes are change in risk of falling, fear of falling, number of falls and fall-related injuries, physical exercise capacity, handgrip strength, body composition, cardiac function, blood parameters, quality of life, risk of sarcopenia, activities of daily living, and cognition over three and six months.

DISCUSSION

The bestform study investigates the change in physical function between seniors performing exercise intervention versus usual care over six months. The results of the study will contribute to the development of effective physical activity concepts in senior care facilities.

Physical Therapist Management of Patients With Suspected or Confirmed Osteoporosis: A Clinical Practice Guideline From the Academy of Geriatric Physical Therapy

A clinical practice guideline on physical therapist management of patients with suspected or confirmed osteoporosis was developed by a volunteer guideline development group (GDG) that was appointed by the Academy of Geriatric Physical Therapy (APTA Geriatrics). The GDG consisted of an exercise physiologist and 6 physical therapists with clinical and methodological expertise. The guideline was based on a systematic review of existing clinical practice guidelines, followed by application of the ADAPTE methodological process described by Guidelines International Network for adapting guidelines for cultural and professional utility. The recommendations contained in this guideline are derived from the 2021 Scottish Intercollegiate Guideline Network (SIGN) document: Management of Osteoporosis and the Prevention of Fragility Fractures. These guidelines are intended to assist physical therapists practicing in the United States, and implementation in the context of the US health care system is discussed.

We Don't Know Our Own Strength: A Survey of Strength Training Attitudes, Behaviors, and Knowledge in Physical Therapists and Physical Therapist Students

OBJECTIVE

Strength training is frequently utilized by physical therapists; however, there has been discussion about whether physical therapists utilize strength training adequately. The purpose of this study was to describe and compare the strength training attitudes, behaviors, and knowledge of physical therapists and physical therapy students and to determine how participant characteristics influenced knowledge scores.

METHODS

An anonymous survey was created in 3 rounds. For round 1, researchers used textbooks to create items assessing demographics, attitudes, behaviors, and knowledge regarding strength training. Rounds 2 and 3 consisted of feedback from 7 content experts until 80% consensus was reached; items were added, removed, or edited based on feedback. The final survey was distributed through social media, list servs, and email targeting physical therapists and students based in the United States. Response frequencies for all items were reported. Overall knowledge scores were calculated by summing correct responses for each item, with a maximum score of 13; scores <70% were considered low. Binomial logistic regression determined which characteristics (demographics, attitudes, or behaviors) influenced whether participants adequately utilized strength training principles (scored ≥70% on knowledge items).

RESULTS

There were 777 physical therapist and 648 student participants. Nearly 90% of therapists and students reported frequently prescribing strength training. Over 48% of therapists felt their professional education did not prepare them to apply strength training (compared with 24% of students), and 68% believed that strength training is inadequately applied in physical therapy (compared with 40% of students). Sixty-two percent of therapists and 55% of students scored ≥70% for knowledge items. Additional strength training education and regular participation in strength training increased the odds of scoring ≥70% on knowledge items.

CONCLUSION

Physical therapists and physical therapy students frequently prescribe strength training despite similarly low knowledge scores. To increase knowledge, greater emphasis on strength training in professional education, continuing education, participation in strength training, or all 3 is warranted.

IMPACT

Strength training is an important intervention used in physical therapy and must be used appropriately to improve the health of patients. According to these findings, strength training education may not currently be optimal, as demonstrated by low knowledge scores by both therapists and students. Further work is needed to determine how knowledge of strength training relates to patient outcomes and also how best to implement strength training in physical therapy education and practice.

Effects of resistance training on insulin sensitivity in the elderly: A meta-analysis of randomized controlled trials

We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) assessing the effect of resistance training in older adults on insulin sensitivity.

METHODS

Cochrane, Embase, PubMed, Web of Science and EBSCO were searched from inception to April 2021. We integrated randomized controlled trials published in English, and participants were non-athletic and aged ≥60 years. The outcome of interest was the change in insulin sensitivity, derived from the homeostatic model of insulin resistance (HOMA-IR) and hemoglobin A1c (HbA1c).

RESULTS

12 RCTs were included in this meta-analysis comparing resistance training (n = 232) with control (n = 209). Resistance exercise significantly reduced HOMA-IR level (d = -0.25, 95% CI, -0.43 to -0.06; P < 0.05) and HbA1c levels of (d = -0.51, 95% CI, -0.84 to -0.18; P < 0.05). Subgroup analysis of HOMA-IR revealed that the variables "population", "training intensity" and "period" had significant effects on HOMA-IR, with the largest effect sizes for high-intensity (d = -0.43, 95%CI, -0.85 to -0.22, P < 0.05) and long-term (more than 12 weeks) (d = -0.43, 95%CI, -0.85 to -0.22, P < 0.05) training programs in older adults without type 2 diabetes (T2D) (d = -0.23, 95%CI, -0.42 to -0.04, P < 0.05). Subgroup analysis of HbA1c suggested that resistance training programs with moderate intensity (d = -0.51, 95%CI, -0.90 to -0.12, P < 0.05) and short term (less than or equal to 12 weeks) (d = -0.49, 95%CI, -0.84 to -0.14, P < 0.05) have greater effects on HbA1c.

CONCLUSION

The findings of this meta-analysis suggest that resistance training is effective for inducing improvement in insulin sensitivity for elderly. Subgroup analysis showed that high intensity and long period of resistance exercise improve HOMA-IR in healthy old adults, and that resistance training with moderate intensity and short period improve HbA1c in T2D old people. More studies with high methodological qualities and large sample sizes need to be done to further confirm our conclusion.

Effect of 12-month supervised, home-based physical exercise on functioning among persons with signs of frailty - Randomized Controlled Trial

OBJECTIVES

To investigate the effects of a 12-month home-based exercise program on functioning and falls among persons with signs of frailty.

DESIGN

A randomized controlled trial with a 1:1 allocation SETTING: Home-based PARTICIPANTS: Home-dwelling persons aged ≥65 years meeting at least one frailty phenotype criteria (n=300).

INTERVENTION

12-month, individually tailored, progressive and physiotherapist-supervised, physical exercise twice a week (n=150) vs. usual care (n=149).

MAIN OUTCOME MEASURES

Functional Independence Measure (FIM), Short Physical Performance Battery (SPPB), handgrip strength, instrumental activities of daily living (IADL), and self-reported falls and physical activity (other than intervention). Assessed four times at home over 12 months.

RESULTS

The mean age of the participants was 82.2 (SD 6.3), 75% were women, 61% met 1-2 frailty criteria and 39% ≥3 criteria. FIM deteriorated in both groups over 12 months, -4.1 points (95% CI: -5.6 to -2.5) in the exercise group and -6.9 (-8.4 to -2.3) in the usual care group (group p=0.014, time p<0.001, interaction p=0.56). The mean improvement in SPPB was significantly greater in the exercise group [1.6 (1.3 to 2.0)] than in the usual care group [0.01 (-0.3 to 0.3)] (group p<0.001, time p=0.11, interaction p=0.027). The exercise group reported significantly fewer falls per person-year compared to the usual care group (incidence rate ratio, IRR 0.47 [95% CI 0.40 to 0.55]; p<0.001). There was no significant difference between the groups over 12 months in terms of handgrip strength, IADL function or self-reported physical activity.

CONCLUSIONS

One year of physical exercise improved physical performance and decreased the number of falls among people with signs of frailty. FIM differed between the groups at 12 months, but exercise did not prevent deterioration of FIM, IADL or handgrip strength.

Knockdown of CNN3 Impairs Myoblast Proliferation, Differentiation, and Protein Synthesis via the mTOR Pathway

Background

Myogenesis is a complex process that requires optimal outside–in substrate–cell signaling. Calponin 3 (CNN3) plays an important role in regulating myogenic differentiation and muscle regeneration; however, the precise function of CNN3 in myogenesis regulation remains poorly understood. Here, we investigated the role of CNN3 in a knockdown model in the mouse muscle cell line C2C12.

Methods

Myoblast proliferation, migration, differentiation, fusion, and protein synthesis were examined in CNN3 knockdown C2C12 mouse muscle cells. Involvement of the mTOR pathway in CNN3 signaling was explored by treating cells with the mTOR activator MHY1485. The regulatory mechanisms of CNN3 in myogenesis were further examined by RNA sequencing and subsequent gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) and gene set enrichment analysis (GSEA).

Results

During proliferation, CNN3 knockdown caused a decrease in cell proliferation and migration. During differentiation, CNN3 knockdown inhibited myogenic differentiation, fusion, and protein synthesis in C2C12 cells via the AKT/mTOR and AMPK/mTOR pathways; this effect was reversed by MHY1485 treatment. Finally, KEGG and GSEA indicated that the NOD-like receptor signaling pathway is affected in CNN3 knockdown cell lines.

Conclusion

CNN3 may promote C2C12 cell growth by regulating AKT/mTOR and AMPK/mTOR signaling. The KEGG and GSEA indicated that inhibiting CNN3 may activate several pathways, including the NOD-like receptor pathway and pathways involved in necroptosis, apoptosis, and inflammation.

Singapore multidisciplinary consensus recommendations on muscle health in older adults: assessment and multimodal targeted intervention across the continuum of care

BACKGROUND

The rapidly aging societies worldwide and in Singapore present a unique challenge, requiring an integrated multidisciplinary approach to address high-value targets such as muscle health. We propose pragmatic evidence-based multidisciplinary consensus recommendations for the assessment and multi-modal management of muscle health in older adults (≥65 years) across the continuum of care.

METHODS

The recommendations are derived from an in-depth review of published literature by a multidisciplinary working group with clinical experience in the care of the older population in both acute and community settings.

RESULTS

The panel recommends screening for muscle impairment using the SARC-F questionnaire, followed by assessment for low muscle strength (handgrip strength or 5-times chair stand test ≥10 s as a surrogate for lower limb strength) to diagnose possible/probable sarcopenia. For uncomplicated cases, lifestyle modifications in exercise and diet can be initiated in the community setting without further assessment. Where indicated, individuals diagnosed with possible/probable sarcopenia should undergo further assessment. Diagnosis of sarcopenia should be based on low muscle strength and low muscle mass (bioimpedance analysis, dual-energy X-ray absorptiometry or calf circumference as a surrogate). The severity of sarcopenia should be determined by assessment of physical performance (gait speed or 5-times chair stand test ≥12 s as a surrogate for gait speed). To treat sarcopenia, we recommend a combination of progressive resistance-based exercise training and optimization of nutritional intake (energy, protein and functional ingredients). High quality protein in sufficient quantity, to overcome anabolic resistance in older adults, and distributed throughout the day to enable maximum muscle protein synthesis, is essential. The addition of resistance-based exercise training is synergistic in improving the sensitivity of muscle protein synthesis response to the provision of amino acids and reducing anabolic resistance. An expected dose-response relationship between the intensity of resistance-based training, lean mass and muscle strength is described.

CONCLUSIONS

Reviewed and endorsed by the Society of Rehabilitation Medicine Singapore and the Singapore Nutrition and Dietetics Association, these multidisciplinary consensus recommendations can provide guidance in the formulation of comprehensive and pragmatic management plans to improve muscle health in older adults in Singapore and Asia.

Heavy resistance training in the management of hip pain in older adults: A case series

Background and Purpose: Resistance training has been shown to improve strength, endurance, and function in healthy older adults. The purpose of this case series was to describe the outcomes of a rehabilitation program consisting of heavy resistance training in older adults for management of hip pain. Case Description: Two male patients, aged 69 and 71, with chronic hip pain, participated in a six-week progressive resistance training rehabilitation program at loads equivalent to 76-81% of their one repetition maximum. Outcomes were assessed at evaluation, three, and six weeks. Outcomes included the Lower Extremity Functional Scale, hip and lumbar mobility, and the Five Times Sit to Stand test. Outcomes: By six weeks, each patient reported 0/10 pain and demonstrated clinically important improvements on the LEFS. Both patients' final scores on the Five Times Sit to Stand test fell below the 15 second value for being at risk for falls. Patient One increased his lifting capacity for the deadlift by 92%, and Patient Two by 56%. Both patients were able to deadlift >70% of their one repetition maximum by the conclusion of this report. Discussion: To our knowledge, this is the first report of the outcomes of utilizing heavy resistance training in elderly adults with hip pain in a rehabilitative setting. Both patients demonstrated clinically important improvements in pain, disability, global lower extremity strength, and function by the conclusion of six weeks duration. Further research is needed regarding the effectiveness of heavy resistance training for the treatment of elderly adults with musculoskeletal pain.

Geriatric Activation Program Pellenberg, a novel physiotherapy program for hospitalized patients on a geriatric rehabilitation ward

BACKGROUND AND PURPOSE

Regaining functional independence and independent living is challenging in hospitalized geriatric patients. Different from community dwelling and institutionalized older people, geriatric patients on rehabilitation wards generally receive more frequent and structured physiotherapy with the primary aim to discharge them to their home or place of residence. There is a paucity of evidence concerning the structure and components of physiotherapy programs to improve functional performance in this particular group. In this paper, we describe how we developed the Geriatric Activation Program Pellenberg (GAPP) based on patients' needs and available literature.

METHODS

We searched the literature on physiotherapy interventions focusing on the core components for improvement of functional performance: strength, balance, function, (gait)speed, coordination, and endurance training. Based on physiotherapist staffing and physiotherapy time allocated to each patient, we organized the practical, daily delivery of the program.

RESULTS

GAPP is a 5-day program, repeated weekly, delivered by physiotherapists and physiotherapy students. Each day, one or a combination of two to three different core components of functional performance is trained intensively in 45-min sessions. A set of standard exercises is constantly adjusted to each patients' capacity. On day 5, there is a mix of these core elements in a group session (e.g., chair-dance, table tennis, karate) and the Berg Balance Scale is completed to evaluate progress.

CONCLUSION

GAPP is a multicomponent physiotherapy program for hospitalized patients on a geriatric rehabilitation ward, aimed at improving functional performance.

The Benefits of Strength Training on Musculoskeletal System Health: Practical Applications for Interdisciplinary Care

Global health organizations have provided recommendations regarding exercise for the general population. Strength training has been included in several position statements due to its multi-systemic benefits. In this narrative review, we examine the available literature, first explaining how specific mechanical loading is converted into positive cellular responses. Secondly, benefits related to specific musculoskeletal tissues are discussed, with practical applications and training programmes clearly outlined for both common musculoskeletal disorders and primary prevention strategies.

Effect of Periodized Resistance Training on Skeletal Muscle During Androgen Deprivation Therapy for Prostate Cancer: A Pilot Randomized Trial

PURPOSE

Prostate cancer survivors (PCS) receive androgen deprivation therapy (ADT) as treatment for recurrent cancer, yet ADT is associated with loss of skeletal muscle and physical function. Resistance training can counter both muscle and physical function loss; however, an understanding of the molecular responses of skeletal muscle to resistance training during ADT is still undefined. This sub-analysis of the original randomized, controlled pilot trial investigated effects of 12 weeks of periodized resistance training on mRNA expression of the anabolic genes IGF-1, myogenin, PGC-1α4 and the catabolic genes myostatin and MuRF-1 in skeletal muscle of PCS on ADT. Secondary aims investigated if changes in lean mass and physical function correlated with changes in mRNA expression.

METHODS

PCS on ADT (n = 17) were randomized to 12 weeks of supervised resistance training (EXE, n = 9) or home-based stretching (STRETCH, n = 8) 3 days per week. Outcomes were assessed at baseline and post-intervention. Muscle biopsies were analyzed by RT-PCR for mRNA expression. Body composition was assessed through dual-energy X-ray absorptiometry, and physical function through muscular strength, timed up and go, stair climb, and 400 m walk.

RESULTS

MuRF-1 mRNA expression was significantly greater in EXE compared to STRETCH post-intervention (P = .005). Change in MuRF-1 mRNA expression significantly correlated with improvements in strength and physical function (P < .05), while change in IGF-1 expression correlated with change in lean mass (P = .015).

CONCLUSION

Twelve weeks of resistance training increased mRNA expression of MuRF-1 in skeletal muscle of PCS on ADT. Elevations in resting mRNA expression of IGF-1, myogenin and PGC-1α4, and reduction in mRNA expression of myostatin that are typically expected following resistance training were not observed.

A six-week inspiratory muscle training and aerobic exercise improves respiratory muscle strength and exercise capacity in lung cancer patients after video-assisted thoracoscopic surgery: A randomized controlled trial

OBJECTIVE

To compare the postoperative outcomes of inspiratory muscle training and aerobic exercise, along with standard care, on lung cancer patients undergoing video-assisted thoracoscopic surgery (VATS).

DESIGN

A parallel-group, single-blind randomized clinical trial.

SETTING

Thoracic surgery ward and outpatient clinic in a teaching hospital.

SUBJECTS

Overall 63 patients underwent VATS were randomly assigned to a triaging (TG, n = 32) or control group (CG, n = 31). A total of 54 patients (TG, n = 26; CG, n = 28) completed the study.

INTERVENTION

TG: six-week threshold inspiratory muscle training and aerobic exercise. CG: standard care.

MAIN MEASURES

Maximum inspiratory pressure (PImax), maximum expiratory pressure (PEmax) lung expansion volume, and 6-min walking test (6MWT) were performed on the day of chest tube removal (baseline), and 2, 6, and 12 weeks postoperatively.

RESULTS

The TG showed significant improvement in PImax at week 6 (71.6 ± 34.9 vs. 94.3 ± 32.8 cmH₂O, P = 0.018), PEmax at week 2 (70.9 ± 24.3 vs. 90.9 ± 28.2 cmH₂O, P = 0.015) and week 12 (76.1 ± 20.2 vs. 98.6 ± 35.3 cmH₂O, P = 0.012), the lung expansion volume at week 2 (1080 ± 433 vs 1457 ± 624 mL, P = 0.02) and week 12 (1200 ± 387 vs 1885 ± 678 mL, P < 0.001), in addition to the 6MWT at week 2 (332 ± 78 vs 412 ± 74 m, P = 0.002), week 6 (360 ± 70 vs 419 ± 60 m, P = 0.007) and week 12 (360 ± 58 vs 402 ± 65 m, P = 0.036).

CONCLUSION

A six weeks of inspiratory muscle training and aerobic exercise had improved respiratory muscle strength and aerobic exercise postoperatively in lung cancer patients after VATS as early as 2 weeks.

The impact of functional exercise on the reversal of acromegaly induced frailty: a case report

BACKGROUND

Acromegaly is an endocrine disease caused by the excess secretion of growth hormone and is responsible for the development of multiple comorbidities that can reduce physiologic reserve. The hypersecretion of growth hormone (GH) affects virtually every organ in the body and can predispose an individual to frailty; a state of vulnerability resulting from cumulative decline across multiple systems. Frailty results in a loss of physiologic reserve and vulnerability to adverse outcomes such as morbidity and mortality. Case Description: The patient was a 73-year-old male with acromegaly who declined into a cycle of frailty following coronary artery bypass graft (CABG) and aortic valve replacement surgery. Prolonged hospitalization and lack of adequate physical stress led to the depletion of reserve in the cardiopulmonary, cognitive, musculoskeletal, and neuromuscular systems, leaving a previously independent adult fully dependent for mobility. Outcomes: The patient participated in a twelve-week multicomponent physical therapy program in a skilled nursing facility. The exercise program was designed and administered to impact multiple systems and provide the necessary overload for adaptation. The patient demonstrated significant improvement in the Berg Balance Scale (BBS), Tinetti (POMA), Functional Outcome Scale (FOS), and returned to independent community ambulation.. Discussion: The case illustrates the effectiveness of a multicomponent functional-based exercise program to improve markers of frailty and reverse functional decline in a frail older adult with acromegaly.

Independent and combined effect of home-based progressive resistance training and nutritional supplementation on muscle strength, muscle mass and physical function in dynapenic older adults with low protein intake: A randomized controlled trial

BACKGROUND

With the aging phenomenon, there is growing interest in developing effective strategies to counteract dynapenia, the age-related loss of muscle strength. The positive effect of progressive resistance training on muscle strength is well known, however, the effect of nutritional supplementation or its synergistic effect along with exercise on muscle strength is not a consensus in the literature, especially in populations with low protein intake.

METHODS

We analyzed the muscle strength (handgrip strength and sit-to-stand test), muscle mass, body mass index, insulin resistance, and physical function (gait speed, timed up & go test, and single-leg-stance test) of 69 dynapenic older adults with low protein intake, before and after the intervention period of three months. The participants were randomly allocated into four groups: resistance training, supplementation, resistance training plus supplementation, and control.

RESULTS

There was a significant group x time interaction on the following outcome measures: handgrip strength (p <  0.001), gait speed (p =  0.023), and sit-to-stand test (p <  0.001). Considering the outcomes that showed a significant difference between and within groups, only the resistance training group and the resistance training plus supplementation group showed a large effect size in handgrip strength, gait speed, and sit-to-stand test, whereas the supplementation group showed a moderate effect size in gait speed. After the intervention period, there was no difference between the resistance training and the resistance training plus supplementation groups.

CONCLUSION

This study reinforces the value of resistance training in improving muscle strength. The nutritional supplementation added no further benefits in this specific population. Registration number at the Brazilian registry of clinical trials: RBR-4HRQJF.

Accepting the Challenge-Moderate-Intensity Exercise with Individuals with Dementia: A Case Series

Background and purpose:

The global impact of dementia demands a response from researchers and clinicians to not only assist with prevention and a cure, but also to assist in the management of symptoms related to this progressive disease. The purpose of this case series is to highlight the participation of 3 individuals with varying levels of dementia in a moderate-intensity functional exercise program.

Intervention:

The intervention, developed using principles from exercise science and a Strength-Based Approach, consisted of 24 sessions of moderate-intensity exercises delivered in participant’s home.

Outcomes:

Each participant completed a pre- and post-assessment including gait speed, strength, balance, depressive symptoms, cognition, and perceived difficulty with activities of daily living. Despite various clinical presentations, each participant successfully completed all 24 sessions with noted improvements in at least two measures.

Effects of 12-month home-based physiotherapy on duration of living at home and functional capacity among older persons with signs of frailty or with a recent hip fracture - protocol of a randomized controlled trial (HIPFRA study)

Background

Health concerns, such as frailty and osteoporotic fractures decrease functional capacity and increase use of health and social care services in the aging population. The ability to continue living at home is dependent on functional capacity, which can be enhanced by rehabilitation.

We study the effects of a 12-month home-based physiotherapy program with 12-month follow-up on duration of living at home, functional capacity, and the use of social and health care services among older persons with signs of frailty, or with a recently operated hip fracture.

Methods

This is a non-blinded, parallel group, randomized controlled trial performed in South Karelia Social and Health Care District, Finland (population 131,000). Three hundred community-dwelling older persons with signs of frailty (age ≥ 65) and 300 persons with a recent hip fracture (age ≥ 60) will be recruited. Frailty is screened by FRAIL questionnaire and verified by modified Fried’s frailty criteria. Both patient groups will be randomized separately to a physiotherapy and a usual care arm. Individualized, structured and progressive physiotherapy will be carried out for 60 min, twice a week for 12 months at the participant’s home. The primary outcome at 24 months is duration of living at home. Our hypothesis is that persons assigned to the physiotherapy arm will live at home for six months longer than those in the usual care arm. Secondary outcomes are functional capacity, frailty status, health-related quality-of-life, falls, use and costs of social and health care services, and mortality. Assessments, among others Short Physical Performance Battery, Functional Independence Measure, Mini Nutritional Assessment, and Mini-Mental State Examination will be performed at the participant’s home at baseline, 3, 6, and 12 months. Register data on the use and costs of social and health care services, and mortality will be monitored for 24 months.

Discussion

Our trial will provide new knowledge on the potential of intensive, long-term home-based physiotherapy among older persons at risk for disabilities, to enhance functional capacity and thereby to postpone the need for institutional care, and diminish the use of social and health care services.

Can Interpreting Nonsignificant Findings Inform the Lessons Learned From an Intervention?

Reducing Disability in Alzheimer's Disease (RDAD) is an evidenced-based intervention for individuals with dementia and their caregivers aimed at reducing the psychosocial strain of the caregiver and improving functional ability of the individual with dementia. Overall efficacy, acceptability, and feasibility outcomes have been published regarding RDAD; however, no specific outcome information has been published on the objective physical performance measures (PPM) of gait speed, functional reach, and balance. Data from the Replication of RDAD (n = 508) was utilized to test the hypothesis that each PPM would show change for participants who completed the program. No significant changes were identified in 3 PPM: gait speed (t = .24, P =.81), balance (t = .23, P = .82), and functional reach (t = -.55, P = .58). To strengthen the research about exercise interventions for individuals with dementia, discussion and interpretation of nonfindings is important for improving intervention designs and methodologies. In the case of RDAD, the intervention protocol may require a sufficient dosage of exercise with respect to fundamental exercise science principles, or there may be misalignment between the intervention and outcome measures.

Sarcopenia associated with renal function in the patients with type 2 diabetes

AIMS

Studies have suggested that low muscle mass is associated with declining renal function in healthy populations, whether the association is relevant to patients with type 2 diabetes is not well understood. This study investigates the association between sarcopenia and estimated glomerular filtration rate (eGFR) and urinary albumin-to-creatinine ratios (UACR) in the patients with type 2 diabetes.

METHODS

Two recruited groups consisted of 793 persons without diabetes (males/females=550/243) and 762 persons with type 2 diabetes (males/females=501/261).

RESULTS

The non-sarcopenia population demonstrated higher ASM/HT(2), GFR (P<0.001) and lower UACR (P＜0.05) than the sarcopenia population. In studied men, the association between ASM/HT(2) and eGFR was statistically significant in the group without diabetes (OR=0.580, P=0.020), a trend which persisted in women (OR=0.491, P=0.014). The association between ASM/HT(2) and UACR persisted in studied women of two groups (OR=0.269, P=0.005; OR=0.405, P=0.008, respectively). The highest quartile of ASM/HT(2) in the non-sarcopenia population exhibited a 3.753-fold risk of abnormal eGFR within the diabetes group (OR=3.753, P=0.020). The cutoff point of ASM/HT(2) to indicate abnormal renal function for population with non-sarcopenia was 6.32kg/m(2) in the group without diabetes and 6.31kg/m(2) in diabetes group.

CONCLUSIONS

Sarcopenia is associated with declining renal function, which induces lower eGFR and higher UACR. In the non-sarcopenia population, ASM/HT(2) presents as renal function risk factor, which perhaps associated with higher muscle mass to induce a greater underestimation for creatinine and urinary albumin.

Treatment of Progressive First Metatarsophalangeal Hallux Valgus Deformity: A Biomechanically Based Muscle-Strengthening Approach

Synopsis Hallux valgus is a progressive deformity of the first metatarsophalangeal joint that changes the anatomy and biomechanics of the foot. To date, surgery is the only treatment to correct this deformity, though the recurrence rate is as high as 15%. This clinical commentary provides instruction in a strengthening approach for treatment of hallux valgus deformity, by addressing the moment actions of 5 muscles identified as having the ability to counter the hallux valgus process. Unlike surgery, muscle strengthening does not correct the deformity, but, instead, reduces the pain and associated gait impairments that affect the mobility of people who live with the disorder. This review is organized in 4 parts. Part 1 defines the terms of foot motion and posture. Part 2 details the anatomy and biomechanics, and describes how the foot is changed with deformity. Part 3 details the muscles targeted for strengthening; the intrinsics being the abductor hallucis, adductor hallucis, and the flexor hallucis brevis; the extrinsics being the tibialis posterior and fibularis longus. Part 4 instructs the exercise and reviews the related literature. Instructions are given for the short-foot, the toe-spread-out, and the heel-raise exercises. The routine may be performed by almost anyone at home and may be adopted into physical therapist practice, with intent to strengthen the foot muscles as an adjunct to almost any protocol of care, but especially for the treatment of hallux valgus deformity.

Feasibility of progressive sit-to-stand training among older hospitalized patients

Background. In older patients, hospitalization is associated with a decline in functional performance and loss of muscle strength. Loss of muscle strength and functional performance can be prevented by systematic strength training, but details are lacking regarding the optimal exercise program and dose for older patients. Therefore, our aim was to test the feasibility of a progression model for loaded sit-to-stand training among older hospitalized patients.

Methods. This is a prospective cohort study conducted as a feasibility study prior to a full-scale trial. We included twenty-four older patients (≥65 yrs) acutely admitted from their own home to the medical services of the hospital. We developed an 8-level progression model for loaded sit-to-stands, which we named STAND. We used STAND as a model to describe how to perform the sit-to-stand exercise as a strength training exercise aimed at reaching a relative load of 8–12 repetitions maximum (RM) for 8–12 repetitions. Weight could be added by the use of a weight vest when needed. The ability of the patients to reach the intended relative load (8–12 RM), while performing sit-to-stands following the STAND model, was tested once during hospitalization and once following discharge in their own homes. A structured interview including assessment of possible modifiers (cognitive status by the Short Orientation Memory test and mobility by the De Morton Mobility Index) was administered both on admission to the hospital and in the home setting. The STAND model was considered feasible if: (1) 75% of the assessed patients could perform the exercise at a given level of the model reaching 8–12 repetitions at a relative load of 8–12 RM for one set of exercise in the hospital and two sets of exercise at home; (2) no ceiling or floor effect was seen; (3) no indication of adverse events were observed. The outcomes assessed were: level of STAND attained, the number of sets performed, perceived exertion (the Borg scale), and pain (the Verbal Ranking Scale).

Results. Twenty-four patients consented to participate. Twenty-three of the patients were tested in the hospital and 19 patients were also tested in their home. All three criteria for feasibility were met: (1) in the hospital, 83% could perform the exercise at a given level of STAND, reaching 8–12 repetitions at 8–12 RM for one set, and 79% could do so for two sets in the home setting; (2) for all assessed patients, a possibility of progression or regression was possible—no ceiling or floor effect was observed; (3) no indication of adverse events (pain) was observed. Also, those that scored higher on the De Morton Mobility Index performed the exercise at higher levels of STAND, whereas performance was independent of cognitive status.

Conclusions. We found a simple progression model for loaded sit-to-stands (STAND) feasible in acutely admitted older medical patients (≥65 yrs), based on our pre-specified criteria for feasibility.

Rethinking Hospital-Associated Deconditioning: Proposed Paradigm Shift

Physical therapists often treat older adults with marked deficits in physical function secondary to an acute hospitalization. These deficits are often collectively defined as hospital-associated deconditioning (HAD). However, there is a paucity of evidence that objectively demonstrates the efficacy of physical therapy for older adults with HAD. Older adults with HAD represent a highly variable and complex population and thus may be difficult to study and develop effective interventions for using our current rehabilitation strategies. This perspective article outlines an innovative framework to operationalize and treat older adults with HAD. This framework may help therapists apply emerging exercise strategies to this population and facilitate additional research to support the total value of physical therapy for older adults in postacute care settings-with value measured not only by improvements in physical performance but perhaps also by reduced rates of disability development, rehospitalization, and institutionalization.
