Recovery muscular paralysis in cerebral stroke patient: a case study using surface electromyography and dynamometery

ABSTRACT

To evaluate the recovery from muscular paralysis in Cerebral Stroke Patients using Surfaced Electromyography [SEMG] and hand dynamometry. Design: SEMG and muscle force recorded from a patient of Cerebral Stroke suffering from hemiparesis. Setting: The records were obtained from various affected and normal muscles of the patient on three consecutive visits at Neuromuscular Lab, Department of Physiology, University of Karachi. Subjects: As case studies a patient who met cerebrovascular accident and was treated at a local hospital was examined for SEMG and hand dynamometry. Main outcome measures: SEMG and hand dynamometry are useful tools to assess recovery in affected muscles in cerebral stroke patients. The muscle force was recorded only from Flexor Digitorum Profundus [FDP] that demonstrated significantly lesser values in the affected FDP than its contra-lateral normal one. While, SEMG parameters have demonstrated significantly higher values in the affected Trapezius [TPZ] and Biceps Brachii [BB] while lesser values in FDP, DI and Gastrocnemius [GAS] on first visit. All of these parameters showed significantly lesser values on third visit, in all the affected muscles. Conclusions: Changes in SEMG and muscle force parameters during recovery from hemiparesis, follows the reorganization in cerebral cortex for the revival of muscular performance
