This study investigated the effects of comprehensive core body resistance exercise on lower extremity motor function in stroke survivors. This resistance exercise was developed to aid stroke patients with various severity to perform this exercise, aimed to improve their core strength, stability, and control. Thirty-four stroke patients aged 47.7±13.16 years old were selected from the Rehabilitation Department, Queen Elizabeth I Hospital in Sabah, Malaysia. All patients underwent supervised training either assistive, active or active resistance exercise, biweekly for 12 weeks. Motor function was evaluated using Fugl-Meyer Assessment Lower Extremity (FMA-LE). The data were collected at baseline and at four weeks training interval. Repeated measures ANOVA and paired t test were employed to analyse the effects of the resistance exercise on lower extremity motor function. The twelve-week resistance exercise showed statistically significant effects on lower extremity motor function, lower extremity, coordination/speed, passive joint motion, and joint pain. However, sensation was found insignificant. Paired t test showed statistically significant improvement in lower extremity motor function, lower extremity, coordination/speed, passive joint motion, joint pain, and sensation. This study suggested that the obtained results indicate that the core body resistance exercise was applicable without any induced negative effect such as spasticity or joint pain.
Paresis of the upper and lower limbs is a typical issue in stroke survivors. This study aims to determine whether core exercises help stroke survivors with very severe motor impairment recover their motor function. This study employed a within-subjects design. Eleven hemiparetic stroke patients with very severe motor impairment (FMA score < 35) and ages ranging from 24 to 52 years old were enrolled in this study. All participants engaged in supervised core exercise training twice a week for 12 weeks. The main outcome measures were Fugl-Meyer Assessment Lower Extremity (FMA-LE) and Fugl-Meyer Assessment Upper Extremity (FMA-UE), which were measured before training and at intervals of four weeks during training. Repeated measures ANOVA was used to analyze the effect of core exercises on motor function performance and lower extremity motor function and upper extremity motor function recovery. There were significant differences in the mean scores for motor function performance, lower extremity motor function, and upper extremity motor function throughout the four time points. A post-hoc pairwise comparison using the Bonferroni correction revealed that mean scores significantly increased and were statistically different between the initial assessment and follow-up assessments four, eight, and twelve weeks later. This study suggests that 12 weeks of core exercise training is effective for improving motor function recovery in patients with very severe motor impairment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
