The Effect of Additional Neurodynamic Intervention in Patients With Chronic Ankle Instability
In Brief
A clinical study evaluating balance training alone and balance training and neurodynamic intervention for the common peroneal nerve for Ankle Sprains. Completed, enrolled 36 participants across 1 site.
Detailed Summary
Approximately 40% of acute ankle sprain would develop into chronic ankle instability (CAI). Chronic ankle instability is characterized by pain, repeated sprains and giving way. Recently, the pathomechanical impairment, sensory-perceptual impairment and motor-behavioral impairment have been documented in the chronic ankle instability model. Previous research revealed that compared to the control subjects, people with CAI had lower pressure pain threshold (PPT). This increased mechanosensitivity of the neural tissues around the ankle might account for pain and dysfunction in people with CAI. Also, the other study indicated that in subjects following ankle inversion sprain there is greater restriction of knee extension on the injured side compared to non-injured side in the slump test with the ankle plantar flexion and inversion, which may suggest the restriction in mobility of the common peroneal tract. However, the effects of neurodynamic intervention, which addresses the mechanosensitivity problems, in people with CAI are still unclear. Therefore, the aim of the study is to investigate the effect of additional neurodynamic intervention on the ankle range of motion, mechanosensitivity, balance performance and self-reported function.

Timeline
Interventions
The subjects will warm up to stretch the lower extremity for 5 minutes. The physical therapist will instruct the patient how to use the foot tripod within 5 minutes. And then, giving him or her balance training. At the first, the patient double legs stand on the ground to throw and catch a ball for 30 seconds, and then one leg stand on the ground to throw and catch a ball for 30 seconds. When finished, the patient can take 1 minutes rest. Second, the patient will finish the prescribed the task stand on different materials, which included the exercise mat, dynair, bosu and foam roller.
The physical therapist will give the patient neurodynamic intervention for the common peroneal nerve, which is performed slider the nerve 2 seconds. The slider technique is repeated 30 seconds for 4 times, each time can be take a rest 1 minutes. The physical therapist will instruct the patient how to use the foot tripod within 5 minutes. And then, giving him or her balance training. At the first, the patient double legs stand on the ground to throw and catch a ball for 30 seconds, and then one leg stand on the ground to throw and catch a ball for 30 seconds. When finished, the patient can take 1 minutes rest. Second, the patient will finish the prescribed the task stand on different materials, which included the exercise mat, dynair, bosu and foam roller.
