| Objective: To observe the effect of isokinetic training of flexor and extensor muscles of hip and trunk on the affected side on the walking function of patients with hemiplegia after stroke. Methods: Sixty patients with hemiplegia after stroke were randomly divided into a control group and an observation group of 30 cases each. The control group received a routine rehabilitation training program. On the basis of this, the observation group was given the isokinetic velocity of the flexors and extensors of the hip and trunk of the affected side additionally. Muscle strength training, the isokinetic strength test and training system before and after 6 weeks of treatment were used to assess the peak torque (PT) of the flexors and extensors of the hip and trunk of the affected side of the patients, and the total work (TW) of the flexors and extensors, and the Italian Walkerview digital treadmill gait analysis system was used to evaluate the joint mobility (ROM), step length, and ground contact length of the hip, knee, and ankle joints of the affected lower limbs. Results: After 6 weeks of treatment, the PT and TW of the flexor and extensor muscles of hip joint and trunk in both groups were significantly increased as compared with those before treatment (all P<0.05), and those in the observation group were significantly higher than in the control group (all P<0.05). The flexion and extension angles of hips, knees and ankles in the two groups were enlarged (all P<0.05), the step length and the duration of touching the ground were increased (both P<0.05), and those in the observation group were more significant than in the control group (all P<0.05). Conclusion: Isokinetic strength training of the flexor and extensor muscles of the hip and trunk of the affected side can significantly improve the walking function of patients with hemiplegia after stroke, which is worthy of clinical reference. |
