Incidence and associated risk factors for falls in adults with intellectual disability

Interventions to reduce falls in community-dwelling adults with intellectual disability: a systematic review

BACKGROUND

People with intellectual disability have a high risk of falls and falls-related injuries. Although people with intellectual disability are at increased risk of falls, there is a need to better understand the efficacy of interventions that can help reduce falls and address risk factors in this population. This systematic review aimed to evaluate the type, nature and effectiveness of interventions undertaken to reduce falls with community-dwelling adults with intellectual disability and the quality of this evidence.

METHOD

Four electronic databases were searched: Ovid MEDLINE, PsycINFO, CINAHL Plus and the Cochrane Library. Studies were included if they involved people aged 18 years or over, at least 50% of study participants had intellectual disability, participants were community-dwelling, and the study evaluated any interventions aiming to reduce falls. Study quality was assessed using the National Institutes of Health study quality assessment tools. Reporting of the review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

RESULTS

Seven studies were eligible for review, with a total of 286 participants and mean age of 50.4 years. As only one randomised trial was identified, a narrative synthesis of results was undertaken. Five studies evaluated exercise interventions, one evaluated a falls clinic programme, and one evaluated stretch fabric splinting garments. Methodological quality varied (two studies rated as good, four as fair, and one as poor). Exercise interventions varied in terms of exercise type and dosage, frequency and intensity, and most did not align with recommendations for successful falls prevention exercise interventions reported for older people. While the majority of studies reported reduced falls, they differed in methods of reporting falls, and most did not utilise statistical analyses to evaluate outcomes.

CONCLUSION

This review identified a small number of falls prevention intervention studies for people with intellectual disability. Although several studies reported improvements in fall outcomes, ability to draw conclusions about intervention effectiveness is limited by small sample sizes and few studies. Further large-scale research is required to implement and evaluate falls prevention interventions specifically for adults with intellectual disability.

Developing an understanding of the risk factors for falls among adults with intellectual disabilities: a commentary

Commentary on: Pope J, Truesdale M, Brown M. Risk factors for falls among adults with intellectual disabilities: A narrative review. J Appl Res Intellect Disabil. 2021; 34: 274-285. 10.1111/jar.12805 Falls are a serious and common problem for people with intellectual disabilities (ID). Whilst there is available evidence on falls risk factors for the general population, there is a lack of awareness and understanding of the contributing risk factors for this population. This commentary critically appraises a recent narrative review which sought to identify the risk factors for falls among people with ID. Clinical practice implications: Community nurses may identify people with ID at risk of falls, and work alongside other healthcare professionals and carers to provide tailored multidisciplinary falls-prevention interventions for individuals with ID living in the community.

The influence of 15-weeks climbing program on the static and dynamic balance of young adults with mild and moderate intellectual disabilities

BACKGROUND

The aim of the study was to assess the effect of climbing on static and dynamic balance and to determine the usefulness of such training in supporting the fitness of young adults with mild and moderate intellectual disabilities.

METHOD

The study involved 47 men and 21 women aged 18-25 years. The experimental group participated in classes on an artificial climbing wall for 15 weeks. At that time, the control group did not participate in any organised sports activities. The balance was assessed twice using tests: a bench walk, a functional reach, a single leg stance with the eyes open and closed, and a BTS P-WALK baroresistive platform.

RESULTS

In the experimental group there were improvements in functional reach test by 7.79 cm (p < .001), balance walk test by 0.47 pts (p = .003), improvements in frontal and sagittal plane stability, and tilting area in the closed eyes test. The changes that were observed in the control group were not statistically significant.

CONCLUSIONS

Climbing activities can be part of a rehabilitation program to improve balance.

Light up: an intervention study of the effect of environmental dynamic lighting on sleep-wake rhythm, mood and behaviour in older adults with intellectual disabilities

BACKGROUND

Evidence-based interventions to improve the sleep-wake rhythm, mood and behaviour in older adults with intellectual disabilities (ID) are limited. Increasing light exposure has been shown to be effective in improving the sleep-wake rhythm, mood, and behaviour in other populations. The current study investigates the effect of installing environmental dynamic lighting in common living rooms of care facilities on sleep-wake rhythm, mood, and behaviour in older adults with ID.

METHODS

A non-randomised, non-concurrent, multiple baseline study was performed from October 2017 to May 2018. Fifty-four participants [mean (SD) age of 63.42 (8.6) years, 65% female] in six care facilities were included. All participants had three baseline measurements (Weeks 1, 5 and 9). Dynamic lighting was installed in Week 10, after which three intervention measurements took place (Weeks 12, 17 and 24). Sleep characteristics and the sleep-wake rhythm were assessed using actigraphy (GENEActiv). Mood was measured with the Anxiety, Depression and Mood Scale (ADAMS) and behaviour with the Aberrant Behaviour Checklist (ABC).

RESULTS

Mixed-effect regression analysis showed a worsening of the primary outcome interdaily stability (P = 0.001). This could be attributed to one care facility, whereas interdaily stability did not change in the other care facilities (P = 0.74). Dynamic lighting led to earlier mid-sleep (P = 0.003) and sleep onset (P < .0001) and improved mood as indicated by lower scores on the ADAMS depression (-0.64 SD, P < 0.001) and social avoidance (-0.47 SD, P = 0.004) subscales. The prevalence of screening above cut-off for depression decreased from 23 to 9.8% (OR = .16, P = 0.003). For behaviour, a decrease was seen in hyperactivity (-0.43 SD, P < 0.001), lethargy (-0.35 SD, P = 0.008) and irritability (-0.33 SD, P < .001) as measured with the ABC. No adverse effects were reported.

CONCLUSION

Installing dynamic lighting in common living areas for older adults with ID improved the mood and behaviour of the residents up to 14 weeks after placement. Integrated dynamic lighting is a promising, undemanding and potentially effective addition to improve mood and behaviour in care organisations for people with ID, but does not seem to do so by improving sleep or sleep-wake rhythms.

Effect of Lower Limb Muscle Fatigue on Fall Risk for Transfemoral Amputee: A Pilot Study

Muscle fatigue is a decline in muscle maximum force during contraction and can influence the fall risk among people. This study is aimed at identifying the effect of fatigue on prospective fall risk in transfemoral amputees (TFA). Fourteen subjects were involved in this study with TFA (34.7 ± 8.1 yrs, n = 7) and normal subjects (31.1 ± 7.4 yrs, n = 7). Fatigue of lower limb muscles was induced with the fatigue protocol. Subjects were tested prefatigue and postfatigue using the standardized fall risk assessment. All results were calculated and compared between pre- and postfatigue to identify fatigue's effect on both groups of subjects. The results showed that the fall risk increased significantly during pre- and postfatigue for TFA (p = 0.018), while there were no significant differences in normal subjects (p = 0.149). Meanwhile, the fall risk between TFA and normal subjects for prefatigue (p = 0.082) and postfatigue (p = 0.084) also showed no significant differences. The percentage (%) of increased fall risk for TFA was 19.2% compared to normal subjects only 16.7%. However, 61.4% increased of % fall risk in TFA after fatigue by using the baseline of the normal subject as the normalized % of fall risk. The increasing fall risks for TFA after fatigue are three times higher than the potential fall risk in normal subjects. The result indicates that they need to perform more precautions while prolonging lower limb activities. These results showed the implications of fatigue that can increase the fall risk due to muscle fatigue from repetitive and prolonged activities. Therefore, rehabilitation programs can be done very safely and precisely so that therapists can pursue fitness without aggravating existing injuries.

Exploring enablers and barriers to accessing health services after a fall among people with intellectual disability

BACKGROUND

Adults with intellectual disability experience high rates of falls making falls prevention an important health need. The purpose of the study was to seek perspectives of older adults with intellectual disability and their caregivers to (a) explore the experiences of older adults with intellectual disability when seeking healthcare services after a fall and (b) identify enablers and barriers when taking up evidence-based falls recommendations.

METHOD

A qualitative exploratory study was undertaken as part of a prospective observational cohort study. Semi-structured interviews were conducted with a purposeful sample. Data were analysed thematically using Colaizzi's method.

RESULTS

Seventeen interviews were conducted (n = 21). Emergent themes demonstrated that participants had limited knowledge about falls prevention. Enablers included individualizing falls prevention strategies. Barriers included not being offered access to established falls prevention pathways.

CONCLUSION

There is an urgent need to develop high-quality falls prevention services for older adults with intellectual disability.
