Primary Outcome Measures

Name	Time	Method
Hand grip strength	4 weeks	Participants will be asked to perform maximum hand grip with the dominant hand with hold for 5 seconds, for three repetitions using the hand held dynamometer (dynamometer, Jamar, United States), a 60 seconds rest interval will be planned in between the repetitions. The mean of the three repetitions will used for calculation of hand grip strength.

Secondary Outcome Measures

Name	Time	Method
pinch strength	4 weeks	The participant will be asked to sit comfortably, with the pinch gauge between the index and middle fingers, and thumb, with the tested arm at the side with the elbow flexed 90 degrees. After five seconds of holding the pinch with full force, take a reading, repeat three times.
Muscle activity of flexor carpi radialis muscle	4 weeks	Muscle activity will be measured utilizing electromyography (EMG) using the Delsys Trigno (DST01) system for flexor carpi radialis muscle.
Muscle activity for flexor carpi ulnaris muscle	4 weeks	Muscle activity will be measured utilizing electromyography (EMG) using the Delsys Trigno (DST01) system for flexor carpi ulnaris muscle.
Muscle activity for extensor digitorum communis muscle	4 weeks	Muscle activity will be measured utilizing electromyography (EMG) using the Delsys Trigno (DST01) system for extensor digitorum communis muscle.
Upper limb function	4 weeks	The upper limb function will be assessed by using the Arms, Shoulders and Hands Disability Questionnaire (DASH) Quick, which is a validated and widely used 11-item questionnaire that evaluates certain impairments and symptoms in the upper limb. the score ranged from 0 to 100, the lower the score, the greater the results.
