Recovery of Muscular Paralysis in Cerebral Stroke patient: A case study using surface Electromyography & Dynamometery.
Pak J Med Sci Jan ;19(4):322-9.

Objective: To evaluate the recovery from muscular paralysis in Cerebral Stroke Patients using Surfaced Electromyography (SEMG) and hand dynamometry. Design: SEMG & 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. Results: 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.
