Brief Summary

Patellofemoral pain syndrome (PFPS) is a common source of knee pain in the physically active population, predominantly in women. The incidence rate of PFPS among athletes is 25 percent, which is higher than that of general population. PFPS is caused by repetitive stress and aggravated in athletes by cycling and running. These symptoms are caused by structural or biomechanical changes of the joint, which becomes exacerbated by activities such as going up and down stairs, sit for a prolonged period, squatting or kneeling, resulting in increased compressive forces in the joint patellofemoral. It is characterized by defused pain in front of knee. Other signs also present are the patellar crepitus, swelling, and joint blockage despite being deemed a multifactorial condition with no single cure, PFPS is commonly attributed to muscular dysfunction, for which conservative rehabilitation is the treatment of choice. Historically, PFPS has been linked to impairments of the quadriceps muscle.

Outcome Measures

Primary Outcomes (3)

• NPRS

  Numerical Pain Rating Scale (NPRS) is a subjective measure in which individuals rate their pain on an eleven-point numerical scale.

  6 weeks

• LEFS

  Lower Extremity Functional Scale (LEFS) is to measure "patients' initial function, ongoing progress, and outcome" for a wide range of lower-extremity conditions.

  6 week

• Y balance test

  Y Balance test is a dynamic test required for proprioception along with strength and flexibility.

Study Arms (2)

Open chain kinetic exercises

EXPERIMENTAL

In open chain exercises extremities are free to move and there is no weight bearing. Subjects performed group of exercises, 3sets of 10 repetitions for each exercise after warm-up and stretching exercises The open kinetic chain exercise program consisted of 1) maximal static quadriceps muscle contractions

Other: Open kinetic chain exercises

Closed Chain Kinetic Exercises

EXPERIMENTAL

In closed kinetic chain exercises extremities are fixed and weight bearing is done. Subjects performed group of exercises, 3sets with 10 repetitions for each exercise after warm up and stretching exercises. The closed kinetic chain exercise program consisted of 1) seated leg presses, 2) one-third knee bends on one leg and on both legs, 3) stationary bicycling, 4) rowing-machine exercises, 5) step-up and step-down exercises. Each exercise in the closed kinetic chain protocol was performed dynamically with a 3-second rest between repetitions.

Other: Closed kinetic chain exercises
