Abstract:

Objective To observe the effect of surface sensation training on walking function of patients after anterior cruciate ligament reconstruction (ACLR).
Methods From January to November, 2021, 56 ACLR inpatients in Beijing Rehabilitation Hospital were randomly divided into control group (n = 28) and experimental group (n = 28). The control group received routine rehabilitation training of 45 minutes a time, while the experimental group received routine rehabilitation training of 30 minutes and surface sensation training of 15 minutes a time, for eight weeks. Their toe-out angle and affected side impulse percentage of plantar seven zones were measured before and after intervention.
Results The toe-out angle of both the healthy and the affected sides decreased in both groups after intervention (t > 4.615, P < 0.001), and it was less in the affected side in the experimental group (t = 2.263, P < 0.05). The impulse percentage in heel medial and heel lateral areas increased in both groups after intervention (t > 4.221, P< 0.001), and it was more in the experimental group (t > 3.651, P< 0.01); while the impulse percentage in middle foot, foot intermediate and foot lateral areas decreased in both groups (t > 3.174, P < 0.01), and it was less in foot intermediate and foot lateral areas in the experimental group (t > 2.366, P< 0.05); the impulse percentage decreased in foot medial and toe areas in the experimental group (t > 3.508, P < 0.01), but there was no significant difference between two groups (t < 1.608, P > 0.05).
Conclusion Surface sensation training can further improve the foot deflection and distribution of impulse of affected side in patients after ACLR during walking, to normalize the load patterns.
