Comparison of Open and Closed Chain Exercises on Pain Function and Balance in Athletes With Patellofemoral Pain Syndrome

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study will be a randomized clinical trial will be conducted in Pakistan sports board Lahore, Model town Sports Club Lahore and Sheikh Zaid Hospital, Lahore. Sample size will be taken to evaluate the effects of open chain exercise and closed chain exercise among athletes with an age group of 18 - 40 years. Non probability convenient sampling technique would be used. Players having an experience of at least 8 months would be a part of study experiencing recurrent knee pain. Participants will be randomly assigned to 2 groups. Group A will include participants who will receive open kinetic chain exercises 3sets of 10 repetitions for each exercise along with the general training. Group B will include the participants who will receive closed kinetic chain exercises 3sets of 10 repetitions for each exercise along with general training.3sessions per week will be given for 6weeks.The subjects will be assessed for pain, function and balance at baseline and after 6weeks of treatment. After collecting data from defined settingit will be entered and analyzed using statistical package for social sciences (SPSS) for Windows software, version 25.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: Open chain kinetic exercises
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
In open chain exercises extremities are free to move and there is no weight bearing.
EXPERIMENTAL: Closed Chain Kinetic Exercises
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
In closed kinetic chain exercises extremities are fixed and weight bearing is done.
