Study Details

Study Description

Brief Summary

To investigate the influence of low intensity pulsed ultrasound on Pain level, pinch grip strength, sensory distal latency of the median nerve, motor distal latency of the median nerve and hand function in patients with chronic carpal tunnel syndrome

Condition or Disease Intervention/Treatment Phase
  • Device: low intensity pulsed ultrasound
N/A

Detailed Description

Carpal tunnel syndrome (CTS) is an entrapment neuropathy caused by compression of the median nerve as it travels through the wrist's carpal tunnel. It is the most common nerve entrapment neuropathy, accounting for 90% of all neuropathies. Early symptoms of carpal tunnel syndrome include pain, numbness, and paresthesia. These symptoms typically present, with some variability, in the thumb, index finger, middle finger, and the radial half (thumb side) of the ring finger. Pain also can radiate up the affected arm. With further progression, hand weakness, decreased fine motor coordination, clumsiness, and thenar atrophy can occur.

Low-intensity ultrasound (LIU) and low-intensity pulsed ultrasound (LIPUS) are known to have positive effects on dentin genesis, cell proliferation, protein synthesis, collagen synthesis, membrane permeability, and integrin expression and to increase cytosolic calcium levels.

Arms and Interventions

Arm Intervention/Treatment
Experimental: low intensity pulsed ultrasound group

low intensity pulsed ultrasound application The following parameters will be used: intensity of 0.3 W/cm2 at a 1megahertz frequency for 20 minutes and pulsed (20%) ultrasound waves and conventional physical therapy program will be used for this group in a form of wrist hand Splint ,Medical Massage (effleurage),Passive stretching for wrist flexor, Carpal mobilization and Strengthening exercise

Device: low intensity pulsed ultrasound
mechanical sound waves

Sham Comparator: control group

Outcome Measures

Primary Outcome Measures

  1. median nerve sensory distal latency [4 WEEKS]

    Measurements of sensory distal latency of median nerve (Antidromic technique ) Recording electrode or Ring electrode (R1, R2): at the index finger the negative electrode is between 2-3 cm to positive electrode (Distance between stimulating and recording sites 5 cm). Stimulating site (S): at the wrist (Middle of the wrist between the tendons to the flexor carpi radialis and palmaris longus) Ground (Earth) electrode (G): between stimulating and recording electrodes will be placed at the palmar surface of the wrist crease.

  2. median nerve motor distal latency [4 WEEKS]

    Measurements of motor distal latency of median nerve (Using Orthodromic technique) Recording (-) active electrode (R1): abductor pollicis brevis (APB). Reference(+) electrode (R2): placed over the first metacarpal-phalangeal joint Stimulating electrode (S): 2 stimulating sites at wrist and antecubital fossa (Cathode toward recording electrode). Ground (Earth) electrode (G): around the wrist crease between stimulating and recording electrodes

  3. pinch grip strength [4 weeks]

    grip strength will be measured using a calibrated baseline hydraulic dynamometer, while the subject will be seated with the arm adducted, elbow flexed at 90 degree, forearm in neutral position firstly, therapist will ask patient to hold the dynamometer between the tip of the thumb and tip of the index finger it called (tip to tip pinch), as hard as possible in the hand to be tested, the patients strongly encouraged to give a maximum effort. One practice trial, Repeat the test 3 times and calculate an average with one min rest in between
