Effects of a Community-Based Familiarization Intervention on Independent Performance of Resistance-Training Exercise Tasks by Adults With Intellectual Disability

Identifying and prioritising strategies to optimise community gym participation for young adults with cerebral palsy: an e-Delphi study

PURPOSE

Identify and prioritise strategies to optimise physical activity participation in the community gym setting for young adults with cerebral palsy.

METHODS

An e-Delphi method was implemented over three rounds with four stakeholder groups (young adults with cerebral palsy, their families, gym staff or exercise professionals, and health professionals). Strategies for change were identified by the stakeholders in round 1. In rounds 2 and 3, strategies for change were rated on the importance for implementation using a 7-point Likert scale (1 being lowest importance, 7 being highest). The consensus was achieved if ≥70% of participants identified a strategy as high importance.

RESULTS

Seventy participants (20 young adults 10 family members, 21 health professionals, and 19 exercise professionals) identified 83 strategies for improving gym participation. Of these, 44 strategies met the consensus criteria. The highest priority strategies related to changing the physical environment, addressing cost barriers, gym staff training, and developing partnerships between sectors.

CONCLUSIONS

Addressing physical accessibility, cost of attendance and the skills of gym staff were agreed upon by the stakeholder groups as priority areas for future resource allocation and research translation. Clinicians and community leisure facilities must work with consumers to implement strategies in their local contexts.

Cognitive and functional evolution in older adults with and without intellectual disability using a multicomponent intervention: A prospective longitudinal study

BACKGROUND

The global population is experiencing accelerated biopsychosocial aging. Cognitive impairment is frequently associated with functional impairment in basic and instrumental daily living activities. To maintain optimal cognitive and functional functioning, health professionals recommend that older adults participate in cognitive training.

AIMS

This study examines the cognitive and functional evolution of older adults with and without Intellectual Disability and the factors associated with favourable evolution following the intervention of a multicomponent programme based on the human occupational model and the person-centred care model.

METHODS AND PROCEDURES

247 people participated. Descriptive and univariate analyses were performed to examine baseline data. The Wilcoxon paired samples test was used to compare cognitive and functional evolution one year after the intervention. Linear regression was used to detect factors predicting favourable evolution.

OUTCOMES AND RESULTS

Both populations improved cognitively. There was no change in basic activities of daily living. There was an improvement in instrumental activities of daily living in the group with Intellectual Disability. None of the variables collected was a predictor of greater improvement.

CONCLUSIONS AND IMPLICATIONS

This study demonstrated that older people with Intellectual Disability who have supports to cope with this life stage can improve their cognitive and functional abilities.

Social Support Initiatives That Facilitate Exercise Participation in Community Gyms for People with Disability: A Scoping Review

People with disability report social support facilitates participation in physical activity. A scoping review explored social support strategies used to facilitate exercise participation for people with disability (aged ≥ 15 years) in community gym settings. Seven electronic databases were searched. Studies were screened for eligibility based on title and abstract followed by full-text review. Data were analysed using content analysis and narrative synthesis. Forty-two articles reporting data from 35 studies were included. Eight types of social support were identified: supervision (n = 30), peer support (n = 21), specialist support (n = 19), orientation (n = 15), education (n = 7), logistical support (n = 6), motivational support (n = 5) and organised social activities (n = 4). Direct supervision was typically provided 1:1 or in small groups by staff experienced working with people with disability. Peer support typically involved support from exercise group participants or a peer mentor. Specialist support was usually provided by a health or exercise professional either directly to people with disability or to the people providing support to them (e.g., trainer). Orientation to the gym environment, equipment and exercise program was usually provided over 1 or 2 sessions. Gym staff may use these strategies to guide the implementation of social supports within their facilities to promote social connectedness and participation for people with disability.

A systematic review and meta-analysis of the effects of aerobic exercise interventions on cardiorespiratory fitness in adults with intellectual disability

BACKGROUND

Adults with an intellectual disability (ID) have low cardiorespiratory fitness (CRF). Low CRF has been associated with a high risk of cardiovascular disease and all-cause mortality. Participation in regular exercise can help adults with ID increase their CRF.

OBJECTIVE

To perform a systematic review and meta-analysis of published, peer-reviewed clinical trials that evaluated the effects of aerobic exercise (AE) interventions on CRF in adults with ID, ages 18-65 years.

METHODS

English-language articles were searched up to June 2021 from 11 electronic databases. Data were extracted using an author-developed form. Two independent authors assessed the risk of bias using the Tool for the Assessment of Study Quality and reporting in Exercise (TESTEX). Meta-analysis was performed using the RevMan 5.3.

RESULTS

Of the 1870 article titles and abstracts screened, 16 articles were included. The average TESTEX score (out of 15) was 8.1 (SD = 3.5, range 2-14). The pooled effect was statistically significant (SMD = 0.41, 95% CI: 0.19 to 0.63, z = 3.59; p = .000) with moderate heterogeneity (I² = 35%, p = .000). Both types of intervention produced statistically significant CRF gains, with interventions that combined AE with resistance, balance, and/or flexibility exercises being slightly more effective (SMD = 0.40, 95% CI: 0.11 to 0.70, p = .007) than non-combined interventions (SMD = 0.42, 95% CI: 0.05 to 0.79, p = .02). Heterogeneity was moderate but non-significant for both types of intervention.

CONCLUSIONS

The review supports the use of AE interventions in promoting CRF in adults with ID. The interpretation is limited by the quality of evidence and by poorly described and/or executed familiarization and measurement protocols.

Effects of resistance training interventions on muscular strength in adults with intellectual disability: a systematic review and meta-analysis

PURPOSE

Muscular strength is critical for adults with an intellectual disability (ID) to promote their mobility, cardiovascular capacity, and performance of daily living/recreational/vocational activities. This article reports the results of the first systematic review and meta-analysis of peer-reviewed clinical trials that evaluated the effects of resistance training (RT) interventions on muscular strength in adults with ID.

METHODS

The protocol was registered with PROSPERO (CRD42020184905). The review focuses on clinical trials that recorded quantitative measures of maximum muscular strength. Eleven electronic databases were searched from their earliest available record up to May 2020. After screening 1996 search records, 11 clinical trials were reviewed.

RESULTS

The RT interventions, while heterogeneous, had an overall significant (p ≤ 0.05) effect on muscular strength in adults with ID, ages 25-58 years. The findings were more significant and less heterogeneous for non-combined RT interventions than for interventions that combined RT exercises with aerobic or balance exercises. The TESTEX overall score was 8.3 ± 3.6.

CONCLUSIONS

RT interventions (particularly when not combined with other exercises) are effective in promoting muscular strength in adults with ID. The limited number of studies and the low study quality scores indicate a potential risk of bias, which limits the interpretation of the findings and warrants further investigation.IMPLICATIONS FOR REHABILITATIONMuscular strength is critical for adults with an intellectual disability (ID) to promote their mobility, cardiovascular capacity, and performance of daily living/recreational/vocational activities.RT interventions are an effective means of improving muscular strength in adults with ID, especially when not combined with other forms of exercise.Testing and assessment protocols used in RT programs should be individualized for adults with ID to accommodate their characteristics and should be implemented under conditions similar to those experienced during the training regimen.It is important to implement familiarization sessions before carrying out muscular strength testing or initiating an RT program to ensure safety, accuracy, and effectiveness of the program for adults with ID.
