Focal Muscle Vibration on Upper Limb Function in Subacute Post-stroke Patients

Stroke is the second leading cause of death, accounting for 11.13 % of total deaths, and the main cause of disability worldwide. The major type of stroke is ischemic, which occurs in about 87% of all stroke cases Stroke has different risk factors, which can be grouped into modifiable and non-modifiable risk factors. Major risk factors for stroke include age, history of cerebrovascular event, smoking, alcohol consumption, physical inactivity, hypertension, diabetes mellitus, cardiovascular diseases, obesity, metabolic syndrome, diet, nutrition, and genetic risk factors. Many new technique used for rehabilitation after stroke includes Constraint-Induced Movement Therapy for Arm or Leg Paralysis, Mirror Therapy for Hand Recovery, Harness the Relentless Force etc. Segmental muscle vibration (SMV) is also a new technique and effective to decrease the hyper-toned muscles spasticity but still less work done on it. SMV with different frequencies have different effects for both flaccid and spastic patients of all 3 stages of stroke. In our study we will work with 60hz and 120hz frequencies to reduce the spasticity of upper limb and improves their functional level.
