Abstract
|
|
|
To exam the effects of active ankle range of motion(ROM) exercise on sciatic nerve movement and provide the evidence that use it to patients with hypomobile sciatic nerve as a nerve mobilization technique.
Methods: The subjects consist of 32 asymptomatic healthy adults(male; 15, female; 17) who have limited passive straight leg raising(PSLR) ranges below 70 degrees. First, examiner measures PSLR angles at three times. Then, subject was instructed perform the active ankle ROM exercise(dorsiflexion and plantarflextion) at limited angle. After each subject completed the active ankle ROM exercise, return the starting position and examiner measures the PSLR angles at three times again.
Results: First, PSLR range was no significant differences between dominant and non-dominant leg(p >.05). Second, active ankle ROM exercise significantly increased PSLR range by mean of degrees(p <.05). Third, there was no learning effects among the measurement trials(p >.05).
Conclusion: These data show that active ankle ROM exercise can mobilize the sciatic nerve. Therefore, it can be applied to patients with hypomobile sciatic nerve(sliding dysfunction) as a neural mobilization technique.
