Brief Summary

this study will be conducted to investigate the effect of Russian current on hand grip strength and functional outcome after carpal tunnel release

Detailed Description

Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy syndrome of the upper extremities , the estimated prevalence is 4-5% in the general population ,it occurs due to median nerve compression in carpal tunnel and it is ten times more common in women ,the most common symptoms are numbness and tingling in the radial 3-1/2 finger, night pain, and paresthesias. Although it is most commonly idiopathic, other causes include trauma, oral contraceptive use, pregnancy, arthritis, diabetes hypothyroidism, and repetitive wrist movements. It is well known that distal radius fractures and their sequelae can cause CTS, this suggests that anatomic changes in bony structures of wrist may also contribute to the development of CTS.Russian current (RC), a well-known neuromuscular electrical stimulation operating at 2500 Hz, has demonstrated significant strength improvement over traditional exercises due to its high tolerance and low pain provocation.There are studies about efficacy of Transcutaneous electrical nerve stimulation on wrist pain in patients with CTR but there is lack of literature about efficacy of RC on hand grip strength and function after CTR so this stidu will be conducted.

Conditions

Carpal Tunnel Syndrome

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: SINGLE

Study Groups

russian current

26 patients will receive Russian current plus a selected physical therapy program three times a week for four weeks.

Group Type: EXPERIMENTAL

russian current

Intervention Type: OTHER

russian current will be is applied in 50Hz sinusoidal bursts with a duty cycle of 50% (10ms on/10ms off). Russian Stimulation (at 2500Hz or 2.5kHz) has been shown to be effective in increasing muscle strength and torque generation through stimulation of type II muscle fiber. The stimulation will be given for duration of 10 minutes on followed by 50 sec off and again 10 sec on, three tims per week plus selsected physical therapy program.

selected physical therapy program

Intervention Type: OTHER

the patients will receive selected physical therapy program in the form of TENS for 15 min, US for 5 min and exercise for 20 min

selected physical therapy program

26 patients will receive a selected physical therapy program alone three times a week for four weeks.

Group Type: ACTIVE_COMPARATOR

selected physical therapy program

Intervention Type: OTHER

the patients will receive selected physical therapy program in the form of TENS for 15 min, US for 5 min and exercise for 20 min
