Abstract

Introduction: Disease progression in MUSCULAR DYSTROPHY (MD) patients results in the gradual loss of ability to produce an appropriate contraction and consequently the loss of necessary force for completing the activities of daily living (ADL). As there is no any recognised treatment for MD and the certain benefit of exercise has not proved yet for these patients. On the other hand, it has been shown that MOTOR LEARNING (ML) may improve the performance, we decided to examine the effect of ML on the upper limb performance in MD patients. Materials and Methods: UPPER LIMB FUNCTION and the effect of ML on upper limb performance was investigated in two experiments. In the first experiment, the performance of 7 facioscapulohumeral MUSCULAR DYSTROPHY (FSHD) patients and 7 age and sex matched healthy volunteers was investigated during a simulated drinking task. Performance was assessed by measurement of electromyographic (EMG) activity of biceps brachii and brachioradialis muscles; elbow joint flexion; shoulder joint flexion and abduction; maximum acceleration at the onset of movement (MAM); movement time (MT) and reaction time (RT), both before and after a 30 min novel complex ML task. In the second experiment, the complex ML task was replaced by a novel simple ML task for another 6 FSHD patients and their age and sex matched healthy subjects. Except that the EMG activity of triceps and deltoid muscles (anterior part) were measured instead of brachioradialis EMG, the other measurements were same as the first study.Results: In both studies, the FSHD patients showed significantly larger values for all parameters except the flexion of shoulder joint and RT compared with controls. While the complex ML resulted in decreases in the brachioradialis EMG activity (P<0.01) and RT (P<0.01) in the FSHD group, the simple ML model resulted in significant changes towards the normal value in all parameters measured except flexion of shoulder.Conclusion: The change in the measured variables towards normal values indicates that MOTOR LEARNING may help to improve performance in FSHD and its effects are more impressive if a simple ML model is used in a therapeutic protocol.
