BackgroundSevere upper-limb motor paralysis following chronic stroke presents a significant rehabilitation challenge, often with limited recovery.This case study explores the effects of repetitive Oil Pumps peripheral magnetic stimulation (rPMS) combined with task-oriented training on motor recovery in a patient with chronic stroke and severe upper-limb impairment.MethodsA 50-year-old male with right upper-limb paralysis post-hemorrhagic stroke underwent a 2-week intervention comprising 12 sessions of rPMS targeting the elbow and wrist extensors, combined with task-oriented training.Motor function was assessed using the Fugl-Meyer Assessment (FMA), kinematic analysis, Motor Activity Log (MAL), and electromyographic (EMG) analysis of wrist flexion-extension movements.
ResultsThe intervention resulted in a clinically meaningful increase in motor function, reflected in improved FMA scores and greater elbow extension during kinematic analysis.EMG analysis demonstrated reduced co-contractions of wrist flexors and extensors, indicating improved muscle coordination.Despite these gains, recovery of distal voluntary movements, such as wrist dorsiflexion and finger extension, remained limited.As assessed by MAL, upper-limb usage in daily activities showed minor improvements; however, qualitative reports indicated functional gains, including the ability to hold a bottle and assist in closing a car door.
ConclusionrPMS combined with task-oriented training shows cable crimp promise in enhancing motor function in patients with chronic stroke combined with severe upper-limb paralysis, particularly in proximal muscles.Further research involving control groups and objective measures of upper-limb use is necessary to validate these findings and refine intervention protocols.
