Abstract:
Objective:To investigate the effect of ultrasound combined with transcutaneous electrical nerve stimulation on pain and function of knee joint in patients with knee osteoarthritis.Method:A total of 122 patients with knee osteoarthritis graded 1 to 3 according to Kellgren-Lawrence (K-L) classification were randomly divided into the experimental group (n=61)and the control group(n=61). The pa-tients in the experimental group were treated with ultrasound combined with transcutaneous electrical nerve stim-ulation on the basis of conventional rehabilitation treatment,and the patients in the control group were only treated with ultrasound on the basis of conventional rehabilitation treatment. The Visual Analogue Scale (VAS) for pain,Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC),walking ability rating scale and 6-minute walk distance were used to evaluate the pain and function of knee joint before treatment,4 weeks after treatment and 3 months after treatment.Result:Before treatment,there was no significant difference between the experimental group and the controlgroup. After 4 weeks of treatment,the VAS score,WOMAC pain and function scores of the two groups were significantly decreased (P<0.05). Improvements in walking ability scores and 6-minute walk distance were significant in both groups (P<0.05). No significant changes were observed in the WOMAC stiffness score between the two groups (P>0.05),The VAS score,WOMAC pain and function score,walking ability score and 6-minute walk distance in the experimental group had statistical significance when compared with those in the control group (P<0.05). At follow-up,except for the WOMAC stiffness score and function score,there were significant differences when compared with those before treatment in the two groups (P<0.05). The VAS score,WOMAC pain score,walking ability score and 6-minute walk distance in the experi-mental group were significantly improved than those in the control group (P<0.05).Conclusion:Ultrasound combined with transcutaneous electrical nerve stimulation could significantly relieve pain,enhances walking function and improve walking ability in people with knee osteoarthritis,but does not have a marked effect on joint stiffness.
