Effectiveness of Phonophoresis With Vitamin B12 on Patients With Mild to Moderate Carpal Tunnel Syndrome: A Randomized Controlled Trial

The purpose of this study is to investigate efficacy of phonophoresis with vitamin B12 on median nerve distal latency, pain level and hand grip strength in patients with carpal tunnel syndrome. At least Fifty four Patients from both sexes will be recruited for this study from various hospitals in 6th October city

• Group A (n = 27): will receive Phonophoresis with Vitamin B12 gel.
• Group B (n = 27): will receive placebo phonophoresis with Vitamin B12 gel.

Median nerve distal latency, hand grip strength and numerical pain rating scale will be measured at baseline and after 3 weeks.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Group A (Vit. B12 Phonophoresis group); Patients in group (A) will receive phonophoresis with Vitamin B12. 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.	Device: Vitamin B12 phonophoresis; 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.; Device: Wrist splint; 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.; Other: tendon and nerve gliding exercises; 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.
Placebo Comparator: Group B (Placebo-Phonophoresis with Vitamin B12); Patients in group (A) will receive placebo phonophoresis with Vitamin B12 gel. Therapeutic pulsed ultrasound using Phyaction UbMF ultrasound device in presence of Vitamin B12 gel 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.	Device: Wrist splint; 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.; Other: tendon and nerve gliding exercises; During tendon-gliding exercises, the fingers will be placed in five discrete positions (straight, hook, fist, tabletop, and straight fist).

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.; Device: Placebo Vitamin B12 phonophoresis; 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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Changes in Distal latency of median nerve sensory distal latency	The Median sensory nerve (SNDL) distal latency was measured according to the American Association of Electrodiagnostic Medicine (AAEM) guidelines with a Neuropack S1 MEB-9004 Nihon Koden (Japan). All measurements were performed in a room with the temperature kept at 25C.	Baseline and after 3 Weeks
Changes in Distal latency of median nerve motor distal latency	The Median motor nerve (MNDL) distal latency was measured according to the American Association of Electrodiagnostic Medicine (AAEM) guidelines with a Neuropack S1 MEB-9004 Nihon Koden (Japan). All measurements were performed in a room with the temperature kept at 25C.	Baseline and after 3 Weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Changes in hand grip strength	The hand grip strength (measured in Kilograms) was evaluated by the same investigator. Grip strength was tested by using Jamar hand held dynamometer following the American Society of Hand Therapists guidelines. The patient's arm was positioned with the shoulder adducted and neutrally rotated, the elbow was flexed at 90, the forearm and wrist were neutrally positioned while the participant was sitting. Patients were instructed to squeeze the handle as hard as they could, do maximal grip contraction for 2-5 s.	Baseline and after 3 Weeks
Changes in numeric pain rating scale (NPRS)	An 11-point Numerical Pain Rating Scale (NPRS; 0 = no pain, 10 = maximum pain) was used to assess the patients' levels of hand pain pre and post treatment.	Baseline and after 3 Weeks
