The Effects of Light Therapy on Sleep, Agitation and Depression in People With Dementia: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

OBJECTIVE: To evaluate the effects of light therapy on the alleviation of sleep disturbances, agitation and depression in people with dementia. METHODS: A search was performed in PubMed, Medline, SCOPUS, Web of Science, EMBASE, CINAHL, Cochrane Library, for studies published between 2000 and 2021. RESULTS: A total of 4315 articles were screened. Sixteen articles were eligible for this review and 11 randomized controlled studies were included in the meta-analysis. Light therapy had a significant effect on reducing the number of awakenings in sleep (n = 4; 95% CI = -.56, -.05; I2 = 0%; SMD = -.31) but was not significant in reducing the wake after sleep onset (n = 3; 95% CI = -.14, .59; I2 = 0%; SMD = .23), agitation (n = 4; 95% CI = -1.02, .45; I2 = 87%; SMD = -.28) and depression (n = 6; 95% CI = -.80, .40, I2 = 85%; SMD = -.20). CONCLUSION: Light therapy appeared to be more effective in terms of alleviating sleep disturbances, rather than reducing agitation and depression, but its long-term effects remain unclear.

Effects of telerehabilitation in occupational therapy practice: A systematic review.

OBJECTIVE/BACKGROUND: This study aimed to review the current evidence on the application of telerehabilitation in occupational therapy practice and its clinical outcomes over the last 10 years. METHODS: A systematic review was performed on studies published in English in the decade 2008 to 2017, retrieved from seven electronic databases (MEDLINE, Cochrane Library, CINAHL, Web of Science, SAGE, Science Direct and EMBASE). Only articles evaluating the use of telerehabilitation to provide occupational therapy services from a distance were included, with no restrictions on pathology, impairment, age, or the nature of occupational therapy intervention. RESULTS: Fifteen articles (three randomised controlled trials, eight quasi-experimental studies, one trial with single-group post-intervention and three case studies) were reviewed. Despite various study designs and outcome measures, most studies indicated positive therapeutic effects of using telerehabilitation in occupational therapy practice. There is insufficient evidence, however, to confirm that telerehabilitation is more effective than the face-to-face model. Little evidence was shown on the long-term effect and cost efficacy. Only two studies used smartphones in their applications. CONCLUSION: Telerehabilitation offers an alternative service delivery model for occupational therapy, not only bridging distance but also offering user-friendly treatment for patients at home. Further research, particularly on the use of the most cutting-edge mobile technology, is needed to determine effectiveness in occupational therapy practice treating various diseases, conditions and impairments and the characteristics of patients, interventions and therapists that lead to the best fit with this alternative and emerging form of service delivery.
