| Purpose: The purpose was to investigate the effects of health education,core stability training,and core stability training combined with kinesio Tape on pain,function,balance,and lower extremity biomechanics in patients with patellofemoral pain syndrome(PFPS).This study may provide a clinical basis for the treatment of PFPS.Methods: Sixty-eight patients with PFPS were recruited and randomly divided into three groups and all subjects received 8 weeks of intervention training.In the health education group(Control group,n=24),three relevant knee knowledge articles were pushed to the subjects weekly through We Chat and no other interventions were made.In the core stability training group(CST group,n=22),subjects performed core stability training and completed 4sets of training movements per training session.Training frequency was 3 times a week separated by at least one day,and training time was no more than 30 minutes.In the core stability training combined with kinesio Tape group(CST+KT group,n=22),subjects were patched with "Y" intramuscular patches on the affected knee joint three times a week for 48 h before training,and then the same training protocol as in the CST group was performed.Before and after the intervention,all subjects’ basic information was counted,and then the patients’ pain,function and balance were assessed using visual analogue scale(VAS),anterior knee pain scale(AKPS)and Y-balance.The biomechanical changes of the lower limb during the single-leg squat were measured with a 3D motion capture system.SPSS22.0 software was used for statistical analyses.Paired-samples t-test was used for comparison of changes before and after treatment,and one-way ANOVA was used for comparison between control group,CST group and CST+KT group.P<0.05 was considered statistically significant.Results:(1)After 8 weeks of intervention,subjects in the CST+KT and CST groups had significantly lower knee VAS scores than the Control group(P<0.05),and subjects in the CST+KT group had significantly lower knee VAS scores than the CST group(P<0.05).Knee VAS scores in the CST+KT and CST groups were lower after the intervention than before the intervention(P<0.01).(2)After 8 weeks of intervention,subjects in the CST+KT and CST groups had significantly higher AKPS scores than the Control group(P<0.05),and subjects in the CST+KT group had significantly higher AKPS scores than the CST group(P<0.05).Subjects in the CST+KT and CST groups had higher AKPS scores after the intervention than before the intervention(P<0.01).(3)After 8 weeks of intervention,subjects in the CST+KT and CST groups scored higher than the Control group in the Y-balance anterior(Y-AN),Y-balance posterior internal(Y-PM)and Y-balance posterior external(Y-PL)directions(P<0.05),Subjects in the CST+KT group had higher scores in the Y-AN direction than the CST group(P<0.05).Performance in the direction of Y-PM and Y-PL was not statistically significant in subjects in the CST+KT group compared with the CST group(P>0.05).subjects in the CST+KT and CST groups had higher Y-AN,Y-PM and Y-PL after the intervention than before the intervention(P<0.01).(4)After 8 weeks of intervention,subjects in the CST+KT and CST groups had lower joint mobility in the coronal and sagittal planes of the hip and knee joints than the Control group(P<0.05),and subjects in the CST+KT group had no statistically significant joint mobility in the coronal and sagittal planes of the hip and knee joints compared with the CST group(P>0.05).Subjects in the CST+KT and CST groups had lower joint mobility in the coronal and sagittal planes of the hip and knee after the intervention than before the intervention(P<0.01).(5)After 8 weeks of intervention,subjects in the CST+KT and CST groups had lower hip internal contraction,peak internal rotation angle and knee abduction and peak external rotation angle than the Control group(P<0.05),and subjects in the CST+KT group had no statistically significant difference in hip internal contraction,peak internal rotation angle and knee abduction and peak external rotation angle with the CST group(P>0.05).The CST+KT and CST groups had lower hip internal contraction,peak internal rotation angle and knee abduction and peak external rotation angle than the Control group after intervention(P<0.01).Subjects had lower hip inversion,peak internal rotation angle and peak knee abduction and external rotation angle after the intervention than before the intervention(P<0.01).(6)After 8 weeks of intervention,subjects in the CST+KT and CST groups had lower displacement of plantar center of pressure in the internal and external directions,knee abduction,and peak external rotation moment than those in the Control group(P<0.05),and subjects in the CST+KT group had no statistically significant difference in displacement of plantar center of pressure in the internal and external directions,knee abduction,and peak external rotation moment from those in the CST group(P>0.05).The CST+KT group and The displacement of plantar center of pressure in the internal and external directions,knee abduction,and peak external rotation moment were lower in subjects in the CST+KT group and CST group after the intervention than before the intervention(P<0.01).(7)After 8 weeks of intervention,the peak knee extension moment was higher in subjects in the CST+KT and CST groups than in the Control group(P<0.05),and there was no statistically significant difference between the peak knee extension moment in subjects in the CST+KT group and the CST group(P>0.05).The peak knee extension moment was higher in subjects in the CST+KT and CST groups than before the intervention(P<0.01).Conclusion:(1)Core stability training and core stability training combined with kinesio Tape coud reduce pain,improve knee function and balance,and improve biomechanics during single-leg squats in patients with PFPS.(2)Core stability training combined with kinesio Tape improved knee pain,function,and Y-balance anterior performance in patients with patellofemoral pain syndrome better than core stability training. |
