Stimulus Phase Duration on Discomfort and Electrically Induced Torque of Quadriceps Femoris

Not Applicable

Completed

• Conditions: Torque; Pain Perception

• Registration Number: NCT01862393
• Lead Sponsor: Universidade Cidade de Sao Paulo

Brief Summary

This study aims to examine the variation in muscle torque and discomfort produced when electrically stimulating quadriceps femoris using pulsed current with three different phase durations in order to establish whether there are any advantages or disadvantages in varying the phase duration over the range examined.

Primary Outcome Measures

Name	Time	Method
Torque	During 4 seconds of electrical stimulation	Torque will be measured using an isokinetic dynamometer. Torque will be registered in Newton meter \[N.m\]

Secondary Outcome Measures

Name	Time	Method
Discomfort	During 6 seconds of electrical stimulation	Discomfort will be measured using a 10 cm visual analogue scale (VAS) ranging from zero (no discomfort) to 10 (worst discomfort imaginable).
