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

Conditions

Patellofemoral Pain Syndrome

Outcome Measures

Primary Outcomes (9)

• Dynamic knee valgus angle

  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.

  6 weeks

• Hip Range of Motion

  It will be measured with goniometer

  6 weeks

• Knee Range of Motion

  It will be measured with goniometer

  6 weeks

• Pain intensity

  Numeric pain rating scale will be used to access pain of the subject pre and post intervention.

  6 weeks

• Gait Speed

  Gait speed is the distance that the patient has covered per unit time Calculated as: Gait speed = Distance (m) x time (s)

  6 weeks

• Cadence

  Cadence is the number of steps patient takes per unit time. Calculated as: Cadence (steps/min) = steps counted x 60 / time (s)

  6 weeks

• Stride length

  Stride length is the distance between two heel strikes of the same foot. Calculated as: SL (m) = speed (m/s) x cycle time (s)

  6 weeks

• Step length

  Step length is the vertical distance between heels of two feet. Calculated as: Step length (m) = stride length/2

  6 weeks

• Cycle length

  Cycle length is the time between the two heel strikes of one foot. Calculated as: Cycle time (s) = time (s) x 2/steps counted

  6 weeks

Interventional group

EXPERIMENTAL

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.

Procedure: McConnell Taping; Procedure: ECCENTRIC EXERCISES:

Interventions

McConnell Taping PROCEDURE

Begin with the patient in supine lying with the knee slightly bent. The knee should be completely relaxed and a foam roller or rolled up towel under the knee. Start the tape in line with the middle of the knee cap at the outer aspect of the knee. Using your thumb on top of the sports tape, gently push the patella towards the inner aspect of the knee whilst simultaneously using your fingers to pull the skin at the inner aspect of the knee towards the patella. Finish this taping technique at the inner aspect of the knee ensuring you have created some wrinkling of the skin at the inner aspect of the knee.

Interventional group

ECCENTRIC EXERCISES: PROCEDURE

Performed for 6 weeks, in 3 sets of 10-12 repetitions each day. Detailed protocol is as under: Warm up phase (5 minutes) It will comprise of following components 5 minutes warm up exercise protocol: Marching in place while swinging your arm, rotating toe touching, walking jacks, leg swings, arm circles, shoulder shrugs Eccentric exercises: Each of the following exercise will be performed for 30 seconds, repetitions and hold time will increase with increasing weeks according to patient's stamina. Straight leg raise, side lying hip abduction, single leg bridging, supported double leg squatting, hip hikes,supported single leg squatting Following is the detailed description of Cool down phase: Hip stretch, cat cow stretch, oblique stretch, lower back stretch, calf stretch, cross body shoulder stretch
