| Objective: To investigate the effectiveness of super laser combined with rehabilitation training on postoperative pain and quality of life following total knee replacement. Methods: From March 2016 to February 2017, 52 patients, whose first diagnosis was knee osteoarthritis, underwent primary total knee replacement in the Guangdong Provincial Work Injury Rehabilitation Hospital. The patients were randomly divided into two groups: the experimental group (super laser group) and control group, with 26 subjects in each group. The patients in the control group received conventional rehabilitation training (i.e., positioning post-surgery, range of motion training, transfer training, balance training, proprioception training and walking ability training), and those in the experiment group were treated with super laser additionally. The rehabilitation effects of the two groups were evaluated respectively before and 6 weeks after operation using Visual Analogue Scale (VAS), Active Range of Motion (AROM), Hospital for Special Surgery (HSS) knee functional score and 12-item short form health survey (SF-12). Results: VAS, AROM, HSS knee functional scores and SF-12 were significantly improved after 6-week treatments in both two groups when compared with those before treatments (P<0.05). The above scores were significantly better in the experimental group than in the control group (P<0.05). Conclusion: The rehabilitation effectiveness was definite for patients who had been given super laser combined with rehabilitation training after primary total knee replacement. The training also had better rehabilitation effectiveness in improving knee, mental function and relieving pain as compared with conventional rehabilitation training. And the training can significantly improve the quality of life of patients. |
