Comparative Effects Of Clamshell And Short Arc Quadriceps Exercises In Patellofemoral Pain (CASCAPE-PFPS)
Comparative Effects Of Clam Shell Exercises And Short Arc Quadriceps Strengthening Exercises On Pain, Functional Disability And Quality Of Life In Patellofemoral Pain Syndrome
This is a research study to compare two different exercises for people who have patellofemoral pain syndrome. Patellofemoral pain syndrome means pain around or behind the kneecap, which is also called "runner's knee".
People in this study will be divided into two groups by chance. One group will do clamshell exercises. This exercise strengthens hip muscles. The other group will do short arc quadriceps exercises. This exercise strengthens thigh muscles near the knee. Both groups will do their exercises for the same number of weeks.
The main goal of this study is to see which exercise reduces knee pain better and helps patients do daily activities more easily. We will also check if quality of life improves after doing these exercises.
Pain level, knee function, and quality of life will be checked before starting exercises and again after finishing the exercise program.
The results may help doctors and physical therapists choose the best exercise for patients with kneecap pain.
研究概览
详细说明
This randomized parallel-group clinical trial will compare the effectiveness of clamshell exercises versus short arc quadriceps strengthening exercises in patients diagnosed with patellofemoral pain syndrome.
Study Design: Participants meeting inclusion criteria for patellofemoral pain syndrome will be randomly allocated into two intervention groups.
Group 1 - Clamshell Exercise Group: Participants will perform clamshell exercises targeting hip abductors and external rotators, specifically gluteus medius and gluteus maximus muscles.
Group 2 - Short Arc Quadriceps Group: Participants will perform short arc quadriceps strengthening exercises focusing on quadriceps femoris muscle, with emphasis on vastus medialis obliquus activation.
Intervention Duration: Both groups will follow supervised exercise protocols for [X weeks]. Frequency and repetitions will be as per standard protocol.
Outcome Measures:
Primary: Pain intensity using Visual Analog Scale, Functional disability using Kujala Anterior Knee Pain Scale, Quality of Life using SF-36 questionnaire.
Assessments will be conducted at baseline, mid-intervention, and post-intervention to compare changes between the two exercise groups.
Hypothesis: Clamshell exercises targeting hip muscles may show superior effects on pain and function compared to short arc quadriceps exercises in PFPS patients.

干预/治疗 |
|---|---|
|
实验性的：Clamshell Exercise Group
Participants in this group will perform clamshell exercises targeting hip abductors and external rotators.
Exercise includes side-lying hip abduction with knees bent at 45 degrees, focusing on gluteus medius and gluteus maximus strengthening.
Sessions will be supervised by physical therapist for [X weeks], [frequency per week].
|
A hip strengthening exercise performed in side-lying position with hips and knees flexed.
Patient opens top knee like a clamshell while keeping feet together to strengthen gluteus medius and external rotators.

实验性的：Short Arc Quadriceps Exercise Group
Participants in this group will perform short arc quadriceps strengthening exercises targeting quadriceps femoris muscle with emphasis on vastus medialis obliquus activation.
Exercise performed from 30 to 0 degrees knee extension in short arc range.
Sessions will be supervised by physical therapist for [X weeks], [frequency per week].
|
A knee strengthening exercise performed in short range of motion from 30 degrees to full extension.
Patient extends knee against resistance while quadriceps muscle is activated, focusing on vastus medialis obliquus.

Change in Pain Intensity
大体时间：Baseline and 12 weeks post-intervention
|
Pain intensity will be assessed using Visual Analog Scale (VAS).
VAS is a 10cm horizontal line where 0 = no pain and 10 = worst pain imaginable.
Patients mark their current knee pain level.
Change in VAS score will be measured from baseline to post-intervention after completion of exercise program.

Change in Knee Function
大体时间：Baseline and 12 weeks post-intervention
|
Knee function will be assessed using Kujala Anterior Knee Pain Scale (AKPS).
AKPS is a 13-item questionnaire specific for patellofemoral pain syndrome.
Total score ranges from 0 to 100, where 100 = no limitation and 0 = maximum limitation.
Change in AKPS score will be measured from baseline to post-intervention.

Change in Quality of Life
大体时间：Baseline and 12 weeks post-intervention
|
Quality of life will be assessed using Short Form-36 Health Survey (SF-36).
SF-36 includes 8 domains: physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional, mental health.
Scores range from 0 to 100 for each domain.
Change in SF-36 scores will be measured from baseline to post-intervention.
