Intervention type: DEVICE
Group type: EXPERIMENTAL
Intervention: Vitamin B12 phonophoresis
Description: Therapeutic pulsed ultrasound using Phyaction UbMF ultrasound device in presence of vitamin B12 gel will be applied over the wrist. The following parameters will be used: intensity of 1.0 W/cm2 at a 1MHz frequency for 5 minutes and pulsed (25%) ultrasound waves to transfer the vitamin B12 gel. This therapy will be applied for 5 min/session, 5 d/wk, for 3 weeks.

Intervention type: DEVICE
Group type: PLACEBO_COMPARATOR
Intervention: Placebo Vitamin B12 phonophoresis
Description: Therapeutic pulsed ultrasound using Phyaction UbMF ultrasound device in presence of Vitamin B12 will be applied over the wrist. The ultrasound probe will be held over the wrist using topical gel containing Vitamin B12 which was the same as in group A. Ultrasound device will seem to be working for 5 min period with light-off position. This therapy will be applied for 5 min/session, 5 d/wk, for 3 weeks.

Intervention: Wrist splint
Description: Patients were instructed to wear a neutral volar splint at night and while performing strenuous activities during the day for 5 weeks. Patients were given forms in order to check if they won't be compliant to the splint application and will be asked to bring the forms at the post treatment evaluation. Patients who won't check the form more than once a week will be regarded as non-compliant to splinting.

Intervention: tendon and nerve gliding exercises
Description: During tendon-gliding exercises, the fingers will be placed in five discrete positions (straight, hook, fist, tabletop, and straight fist). During the median nerve-gliding exercise, six different hand and wrist positions will be used to mobilize the median nerve. During these exercises, the patient must maintain the neck and the shoulder in neutral position with a supinated forearm and elbow flexed 90 degrees. Each position must be maintained for 5 seconds. Each exercise will be repeated 10 times at each session and patients will be encouraged to apply exercise 3-5 times per day for 5 weeks.
