Effects of Eccentric Exercises on Gait Parameters in Patellofemoral Pain Syndrome: A Quasi-Experimental Study

Not Applicable

Recruiting

• Conditions: Patellofemoral Pain Syndrome
• Interventions: Procedure: McConnell Taping

• Registration Number: NCT06387524
• Lead Sponsor: Foundation University Islamabad

Brief Summary

This study is a quasi experimental and the purpose of this study is to determine the effects of eccentric exercises on gait parameters in patellofemoral pain syndrome: a quasi - experimental study

Detailed Description

The purpose of this study is to determine the effects of eccentric exercises on gait parameters in patellofemoral syndrome : a - quasi experimental study

Pain , gait parameters, ROM and dynamic knee valgus angle of young adults (age : 18-35 years ) will be determined using:

1. Numeric pain rating scale

2. Goniometer

3. 30 meter walk test

4. dynamic knee valgus angle via kinovea software Data will be before and after the intervention protocol for each participant. Data collection procedure: Participants of interest would be approached and explained about the research. Informed written consent will be taken. Pre and post intervention scores will be recorded.

Arm && Interventions

Group	Intervention	Description
Interventional group	McConnell Taping	There will be only one group in the study. After application of Mc Connell taping, patients will perform eccentric exercises taught by the therapist for 6 weeks. Mentioned below are detailed protocols for the treatment of patellofemoral pain syndrome.

Primary Outcome Measures

Name	Time	Method
Gait Speed	6 weeks	Gait speed is the distance that the patient has covered per unit time Calculated as: Gait speed = Distance (m) x time (s)
Dynamic knee valgus angle	6 weeks	2D analysis using a video camera will be used to analyze dynamic knee valgus, specifically the inward movement of the knees during task performance. Participants will be instructed to perform a single-leg squat task. They will also be directed to adequately flex the contralateral knee to prevent the foot from touching the floor. A digital video camera positioned at a 90-degree angle to the frontal plane will be placed on a tripod stand 2m in front of the participant's landing point at knee level for 2D video recording purposes. The recorded video will be processed into slow motion and exported to Kinovea software. Dynamic knee valgus angle (DKVA) will be calculated at the intersection point of two lines: the first line connecting markers placed on the anterior superior iliac spine (ASIS) and the middle of the tibio femoral joint, and the second line connecting the middle of the tibio femoral joint and the middle of the ankle mortise.
Pain intensity	6 weeks	Numeric pain rating scale will be used to access pain of the subject pre and post intervention.
Knee Range of Motion	6 weeks	It will be measured with goniometer
Step length	6 weeks	Step length is the vertical distance between heels of two feet. Calculated as: Step length (m) = stride length/2
Hip Range of Motion	6 weeks	It will be measured with goniometer
Stride length	6 weeks	Stride length is the distance between two heel strikes of the same foot. Calculated as: SL (m) = speed (m/s) x cycle time (s)
Cycle length	6 weeks	Cycle length is the time between the two heel strikes of one foot. Calculated as: Cycle time (s) = time (s) x 2/steps counted
Cadence	6 weeks	Cadence is the number of steps patient takes per unit time. Calculated as: Cadence (steps/min) = steps counted x 60 / time (s)
