Abstract
Background and Aims One of the most common causes of knee pain is knee osteoarthritis (KOA). It is a degenerative joint disease, mostly seen in older people. The present study aims to compare the immediate effects of local muscle vibration (LMV) and kinesio tape on quadriceps muscle strength, knee joint proprioception, and pain in people with KOA.
Methods This is a quasi-experimental study with a pre-test/post-test design that was conducted on 34 people with KOA aged 45-65 years. They were divided into two groups of 17, including LMV and kinesiotape. For the kinesio tape group, the tapes with 50% stretch were attached to the quadriceps muscles with Y and I patterns from the beginning to the end of the muscles. The other group received LMV at a frequency of 60 Hz applied to the knee front and the quadriceps muscle four times, each session for 5 minutes, considering a 60-second rest interval. The muscle strength was measured using an isometric dynamometer, while the knee joint proprioception was assessed using the joint position sense test and goniometry of digital images, and pain was evaluated using the visual analogue scale (VAS).
Results No significant difference was observed between the two groups in the improvement of quadriceps muscle strength (P=0.49) and knee joint proprioception (P=0.972) after intervention. However, a significant reduction was observed in pain (P=0.006), where the LMV group showed more reduction than the kinesio tape group. In the within-group comparison of both groups, results showed that the quadriceps muscle strength was not significantly different before and after intervention in the LMV (P=0.262) or kinesiotape (P=0.088) groups. The knee joint proprioception showed no significant difference in the LMV (P=0.090) or kinesiotape (P=0.087) group, either. However, the pain had a significant decrease in both groups after intervention (P=0.001).
Conclusion The immediate effects of LMV and kinesio taping on improving quadriceps muscle strength and knee joint proprioception in people with KOA are not statistically significant. Neither intervention is superior to the other regarding quadriceps muscle strength and knee joint proprioception. Both interventions can reduce knee pain immediately in people with KOA, where LMV is more effective than kinesio taping.
