Objective:
To compare the changes in gait parameters before and after the treatment of lateral ankle sprain using the rotating-pulling-poking manipulation, and explore the potential bio-mechanical mechanism of this manipulation.
Methods:
Forty patients with lateral ankle sprains were randomly divided into two groups in a 1:1 ratio using a random number table. The experimental group were treated by rotating-pulling-poking manipulation and elastic bandage external fixation, while the control group were treated by ice compress and elastic bandage external fixation. The treatment courses of the two groups were both 2 weeks. We used a three-dimensional motion capture system for kinematic measurements and a Bertec gait analysis force measurement system for mechanical measurements, and compared the changes in gait parameters between the two groups of patients before and after treatment.
Results:
Intragroup comparison showed that the support time, swing time, peak of back extension, peak of plantar flexion, peak of toe pedal force, and peak of heel landing force of the affected feet in the experimental group were significantly improved compared to those before treatment (P < 0.05). The swing time of the affected feet in the control group was significantly improved compared to that before treatment (P < 0.05). The inter group comparison showed that the gait speed, stride length, peak of back extension, peak of plantar flexion, peak of toe pedal force, and peak of heel landing force of the affected feet in the experimental group were significantly better than those in the control group (P < 0.05).
Conclusions:
The rotating-pulling-poking manipulation can effectively improve the patient's gait and range of motion of the affected ankle joint, and enhance the negative gravity in the vertical direction of the affected foot, and the braking and driving forces in the front and back directions. This may be the potential biomechanical mechanism of the rotating-pulling-poking manipulation for treating lateral ankle sprain.
