The effect of passive range of motion exercise on motor function of patients in acute phase of stroke

The study was conducted to examine the effect of passive range of motion exercises on motor function of patients in acute phase of stroke. Stroke is one of the most common cerebrovascular disorders. Continuous repetitive exercises in the first six month of stroke may restore significant part of sensory-motor function. In a randomized controlled trial، the patients with moderate or sever ischemic stroke who experienced hemiparesis or hemiplegia were recruited. Motor function level of defected limb was assessed based on “modified ashworth scale” and motor strength scoring tool. Patients in experimental group (n=37) received passive range of motion exercises، within the 48h of onset of stroke، 6-8 times with 30-45 minutes duration. Patients in control group (n=24) received conventional care. The groups were compared one month after intervention. The most recovery was found in upper extremity strength after first month (3. 45) relative to basic assessment (2. 36). In experimental group، motor strength of upper and lower extremity improved، one month after intervention (P<0. 0001). The results showed recovery in motor strength just in upper extremity of control group، after one month (P=0. 012). Intervention had no effect on muscle tone. According to more positive changes in motor function of experimental group after one month، it is suggested to apply the intervention for this group of patients.
