Kinesiology tape versus non-standardized tape in the treatment of balance in non-operated anterior cruciate ligament rupture patients: a randomized controlled trial.

PURPOSE/AIM: Anterior cruciate ligament injuries are the most common traumatic ligament injuries of the knee, which course with impaired balance. The aim of the present study was to analyse the effect of kinesiology tape on balance in subjects with non-operated anterior cruciate ligament rupture. MATERIALS AND METHODS: 36 subjects were randomly assigned to the kinesiology tape group (KT = 20) and the non-standardized tape group (NST = 16). Balance was assessed in the following 3 conditions: no bandage, immediately after application, and after four days of use. The outcome measures used were the Sensory Organisation Test (SOT), assessed by computerised dynamic Posturography (CDP), the modified star excursion balance test (mSEBT), the Spanish version of the KOOS and the Lysholm Knee Score. A 2-way repeated measures analysis of variance (ANOVA) was performed, with time as a within-subject factor and group as a between-subjects factor. Bonferroni correction was applied when the ANOVA was significant. RESULTS: ANOVA showed that there was no significant interaction between group and time for all outcome measures. However, a significant effect on the time factor was observed for: composite SOT score in both groups immediately after tape application; composite SOT after four days of use in the KT group; mSEBT in the KT group immediately after tape application. The KOOS improved in both groups after four days of tape use, while the Lysholm Knee Score improved only in the NST group. CONCLUSIONS: No differences were observed between the KT or NST groups in balance measurements.
