Abstract

Background: Multiple sclerosis (MS) is a chronic neurodegenerative disorder of the central nervous system (CNS) that commonly affects young and middle-aged adults. Neurodegeneration of the CNS affects its functions such as sensorimotor, autonomic and cognitive functions. Affectation of motor function can result in disability in performance of daily life activities. Thus, effective rehabilitation interventions are needed to help prevent disability in patients with MS. One of these interventions is the constraint induced movement therapy (CIMT). The CIMT is used to improve motor function in patients with stroke and other neurological conditions. Recently, its use in patients with MS is gaining ground. The aim of this study is to carry out a systematic review and meta-analysis to determine from the literature, the effects of CIMT on upper limb function in patients with MS. Methods: PubMED, Embase, Web of Science (WoS), PEDro, and CENTRAL were searched until October 2022. Randomized controlled trials in patients with MS who were 18 years and above were included. Data on the characteristics of the study participants such as disease duration, type of MS, the mean scores of the outcomes of interest such as motor function and use of the arm in daily activities, and white matter integrity were extracted. Methodological quality and risks of bias of the included studies were assessed using PEDro scale and Cochrane risks of bias tool. The data was analysed using both narrative and quantitative syntheses. In the quantitative synthesis, random effect model meta-analysis of the mean and standard deviation of the scores on the outcomes of interest and the study sample size (for both the CIMT and the control group) post intervention was carried out. In addition, percentage of variation across the studies due to heterogeneity (I 2) was considered significant when it is between 50% and 90% at p < 0.05. Results: Two studies comprising of 4 published articles with good methodological quality were included in the study. The results showed that, CIMT is safe and improved white matter integrity, motor function, muscle strength, dexterity, real-world arm use and biomechanical parameters post intervention. However, although there was a trend towards better improvement in the CIMT group in all the outcomes, there was no statistically significant difference between groups in motor function (SMD=0.44, 95% CI=-0.20 to 1.07, p = 0.18) and quality of movement (SMD=0.96, -1.15 to 3.07, p = 0.37). Conclusion: CIMT can be used in patients with MS since it is safe as well as effective at improving functional outcomes. However, more studies are required to confirm its safety and effectiveness.
