For comparison at a constant value, the records obtained by giving 2.5 mA which was the appropriate stimulus based on average supramaximal stimulus threshold, were evaluated.
For the evaluation of test results, preoperative and postoperative mean and standard deviations were calculated for latencies, amplitude, wave duration, and supramaximal stimulus thresholds in the study and control groups.
When the preoperative and postoperative supramaximal stimulus threshold levels, as measured by EMG, were evaluated between study groups, no statistically significant difference was detected (p>0.05).
In the present study, the noxious stimulus used for determination of the [ISO.sub.MAC] may not be considered a supramaximal stimulus
(VALVERDE et al., 2003).
A supramaximal stimulus was given at wrist and at elbow near volar crease of brachial pulse.
A supramaximal stimulus was given at ankle on the point midway between the medial and lateral malleoli with feet slightly dorsiflexed.
A supramaximal stimulus was sufficiently painful to be likely to impose a marked restriction on the supply of volunteers!
The TOF ratio is a technique that compares the twitch height of the fourth twitch with that of the first when supramaximal stimulus is applied at routinely 2 Hz.
: During each contraction and when the force reached a plateau, a supramaximal stimulus
was delivered to the musculocutaneous nerve over the motor point.
[M.sub.max] was elicited using a supramaximal stimulus (~110%).
After the treatment these fibres likely possess a RPMS-induced decline in their responsiveness to the supramaximal stimulus. Therefore we suggest that the impairment of the maximal M wave is due to alterations in the peripheral structures below the point of stimulation which modified the integrity of neuromuscular propagation.
