- Lead Sponsor
- Faculty of Physical Therapy Cairo University
- Brief Summary
There was a significant difference between both groups concerning pain pressure threshold favouring study group (p value < 0.05), also there was a significant difference between pre and post measures of sensory nerve conduction velocity, and latency in study group (p value < 0.05). However there was no significant effect on median nerve motor parameters (p value > 0.05).

- Primary Outcome Measures
Name Time Method The study included testing of motor and sensory conduction velocity studies motor nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV). All measurements were done under standard room temperature of 25°C. The participants were informed about the sensation they were going to experience during the EMG measurement. The skin under the stimulating, recording and ground electrodes was cleaned with alcohol to reduce the skin resistance, gel was applied to electrodes for good conduction and electrodes were fixed firmly with adhesive tape
- Secondary Outcome Measures
Name Time Method A pressure algometer (Pain Diagnostics and Treatment Inc, Italy) was used to quantify the pressure pain threshold (PPT The PPT was the amount of pressure in pounds (lb) that each participant immediately perceived as painful, the measurement point was standardized midway between two stimulating electrodes. Once the initial contact was made, the manual force was applied perpendicularly onto the skin through the circular probe head (1 cm2 surface area) of the algometer. The force was increased at a steady rate until the PPT was registered. PPT was determined by the subject’s verbal report when a pain sensation was elicited. As participants were instructed to say Stop when the pressure became painful. PPT was measured before MES application and immediately after, and after 30 min of MES application. The mean of three successive measurements was taken for each study time
