Objective To investigate the effect of isokinetic training on stiff knees after fracture arrest. Methods 38 fracture patients were divided into observation group (n=19) and control group (n=19) by the medical number. Both 2 groups received the Chinese herbs fumigation and joint mobilization. Besides, the observation group received the isokinetic training, while the control group received the instrument training. The range of motion (ROM), maximum peak torque (PT), peak torque/body weight (PT/BW), average power (AP), and hamstrings/quadriceps (H/Q) were tested before and 16 weeks after training. Results The flexion, straightness and flexion radian became significantly better after training. The flexion and the increase of the flexion radian were significantly better in observation group than in control group after training. All indexes of the isokinetic test significantly improved after training (P<0.001) except H/Q (P>0.05). ROM、PT、PT/BW and AP of the knees joint were significantly better in the observation group than in the control group (P<0.001) after training, while there was no significant difference in H/Q between 2 groups (P>0.05) after training. Conclusion Isokinetic training can promote recovery of stiff knees of femur fracture.

Objective To investigate the effect of neuromuscular activation on patients with low back pain after lumbar vertebra fracture operation. Methods 60 low back pain patients who received lumbar vertebra fracture operation were divided into treatment group (n=30)and control group (n=30). Both groups received 20 times of frequency treatments for 4 weeks. While the treatment group received the lumbar stability treatment with neuromuscular activation, and the control group received back muscle strengthen treatment. They were assessed with visual analogue scale (VAS) for pain and Short Form of Health Survey (SF-36) before, 4 weeks and 6 months after treatment. Results The scores of VAS and SF-36 was not significantly different between 2 groups (P>0.05) before treatment, and was significantly different (P<0.05) 4 weeks after treatment and later. Both the scores of VAS and SF-36 improved in both groups after treatment (P<0.05). Conclusion Neuromuscular activation can relieve low back pain after lumbar vertebra fracture operation and improve the quality of life.

ObjectiveTo observe the clinical effect of the rehabilitation on the degenerative scoliosis after the interbody fusion and internal fixation.Methods50 patients with degenerative scoliosis and received the interbody fusion and pedicle screw fixation were divided into the rehabilitation group and the control group. Results2 months after operation, the scoliosis coronal Cobb's angle were corrected from (34.11±9.36)° before operation to (23.08±9.16)°. 3 months after operation, the scores of JOA scale, the investigation of quality of life and satisfaction all resulted in better outcome in the rehabilitation group than the control group. ConclusionThe rehabilitation training after operation can reduce complications and improve the quality of life.

ObjectiveTo evaluate the effect of the comprehensive rehabilitation training, including multi-joint isokinetic muscle strength, balance, and weight-support training, on the senile patients after total hip arthroplasty. Methods50 patients after total hip arthroplasty were divided into group A (n=25) and group B (n=25). The group A received the comprehensive rehabilitation training combined with the 3 systems, while the group B received the routine rehabilitation training. They were assessed with the Harris scale and the life satisfaction before and 4, 8 and 12 weeks after rehabilitation. ResultsCompared with that before rehabilitation, the Harris score of all the patients improved 8 weeks after rehabilitation (P<0.05), while it improved more in the group A than in the group B (P<0.05). The incidence of hip joint recovery was more in the group A than in the group B as well (P<0.05). The life satisfaction improved in both groups 4 weeks after rehabilitation (P<0.01), and it was more in the group A than in the group B 12 weeks after training (P<0.05). ConclusionThe rehabilitation combined with isokinetic, balance, weight-support training can promote the functional recovery after total hip arthroplasty
