received sensory electrical stimulation and task specific training program

received task specific training program only. Patients were tested pre and post treatment by Grip dynamometer, Pinch dynamometer, Digital goniometer and Action Research Arm Test Scale (ARAT).

peripheral sensory electrical stimulation on median, ulnar, and radial nerves of affected upper limb, simultaneously with Task Specific Training program which included four subtests of Action Research Arm Test scale.

The patient seated with his/her shoulder adducted and naturally rotated, elbow flexed at 90 degrees, forearm in neutral position, and wrist between 0- and 30-degrees dorsiflexion and between 0- and 15-degrees ulnar deviation. The Jamar hand dynamometer was set to the second handle position from the inside. Lightly hold around the readout dial to prevent inadvertent dropping. After the patient was positioned properly, the following statement was used "Squeeze as hard as you can…. harder …. harder…. relax" (16). The scores of three successive trials were recorded for each tested hand. The average score of three trials was compared to the normative data on the other side, which is in pounds.

Goniometer was used to assess wrist flexion-extension.

Three types of pinches were typically evaluated because they are involved in accomplishing occupational tasks and activities efficiently. In Tip Pinch: The patient pinched the ends of the pinch meter between the tips of the thumb and index finger. The test was administered by first giving the patient instructions and a demonstration, "Ready? Pinch as hard as you can." The patient was urged on as he or she attempted to pinch. The average of three trials was recorded. In Lateral Pinch (Key Pinch): The patient pinched the meter between the pad of the thumb and the lateral surface of the index finger. In Palmar Pinch (Three-Jaw Chuck): The patient pinched the meter between the pad of the thumb and the pads of the index and middle fingers

Patients who achieve a maximum score on the first (most difficult) item are credited with having scored 3 on all subsequent items on that scale. If the patient scores less than 3 on the first item, then the second item is assessed. This is the easiest item, and if patients score 0 then they are unlikely to achieve a score above 0 for the remainder of the items and are credited with a zero for the other items. The maximum score on ARTS is 57 points (possible range 0 to 57).
