About

The study purpose is to investigate the effectiveness of a program combining biomechanical taping with lower extremity neuromuscular exercises for runners with patellofemoral pain syndrome (PFPS) and hallux valgus

Full description

This will be a single-blind, experimental study with two treatment groups. A total of 30 college athletes with PFPS and hallux valgus and majoring in long distance running or soccer, or recreational runners in Taipei metropolitan area will be recruited. A set of clinical examination will be conducted to rule out abnormal knee structures, pathologies, or injuries apart from PFPS. The lower extremity alignment as well as hip and knee kinematics during a step down test will be tracked using Noraxon's myoMOTION system. Muscle activation of the muscles controlling the hip and knee movements during the step down test will be recorded using TELEmyo DTS of Noraxon. Hallux valgus angle will be measured with surface markers on photographs. Knee pain level will be rated in a visual analog scale. The investigators will analyze the data with Statistical Product and Service Solutions (SPSS) for Windows. Repeated-measure ANOVAs will be used to examine group-by-time interaction on all the outcome variables. All significance level will be set at 0.05.

30 participants in 2 patient groups

Combined training group
Experimental group
Description:
Biomechanical taping will first being applied to the participants of the combined training group. They will be asked to perform following exercises in this session afterwards. As the treatment session goes on, a set of foot intrinsic muscle strengthening exercise and lower extremity neuromuscular exercise will be provided.
Treatment:
Other: combined training
Proximal training group
Active Comparator group
Description:
For participants of the proximal training group, only a set of lower extremity neuromuscular exercise will be provided. This set of exercises is designed to be the same as for participants of combined training group.
Treatment:
Other: Proximal training
