IRCT2014070518362N1 IRCT 2015-12-26 Ahvaz Jundishapur University of Medical Sciences, Vice Chancellor for Research Development and Techn Comparison of the Effects of Knee and Hip Muscle Exercises and Isolated Knee Muscle Exercises in Treatment of Anterior Knee Pain Comparison of the Effects of Knee Exercises and Knee Exercises with Additional Hip Strengthening Exercises on Landing Kinematics in Females with Patellofemoral Pain Syndrome 2014-12-01 anticipated 76 Complete https://irct.ir/trial/16672 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Other design features: Table of random numbers will be used to simply assign the subjects in two groups of treatment The examiner will not be aware of which intervention will be administered to which subject. The patients aware of the existence of two different groups, but do not know about their groups (treatment or control). N/A Patellofemoral Pain Syndrome. Intervention 1: Intervention 1 : The treatment for the individuals in the knee exercise group includes stretching and strengthening of the knee musculature. Each individual will receive 12 sessions of treatment with the frequency of three sessions per week for 45 minutes. For strengthening exercises, the amount of load will be standardized to 70% of the 1-repetition maximum with no pain. For exercises using elastic band, the resistance will be standardized to the maximum resistance that each individual can use to complete 10 repetitions of the exercise. The maximum load and resistance will be determined in the first session, and will be evaluated weekly for any required adjustments. Stretching of the hamstrings and ankle plantar flexors, quadriceps, and iliotibial band will consist of three 30-second stretches, assisted by therapist. Intervention 2: Intervention 2 : Individuals in the knee and hip exercise group will perform the hip abductor and lateral rotator muscles strengthening exercises in addition to knee musculature stretching and strengthening exercises. Each individual will receive 12 sessions of treatment with the frequency of three sessions per week for 45 minutes. For strengthening exercises, the amount of load will be standardized to 70% of the 1-repetition maximum with no pain. For exercises using elastic band, the resistance will be standardized to the maximum resistance that each individual can use to complete 10 repetitions of the exercise. The maximum load and resistance will be determined in the first session, and will be evaluated weekly for any required adjustments. Stretching of the hamstrings and ankle plantar flexors, quadriceps, and iliotibial band will consist of three 30-second stretches, assisted by therapist.
