Relationship Between Knee Pain And Proprioception During Single Leg Squat In Patellofemoral Pain Syndrome (PPS)
調査の概要
詳細な説明
Patellofemoral pain syndrome (PFPS) is one of the most prevalent knee problems that interfere with everyday activities and function. The prevalence of Patellofemoral pain syndrome varies, affecting between 22% and 40% of the general population and up to 70% in athletes engaged in running and jumping sports, with a higher incidence reported among females and individuals aged 15-30 years.Impaired proprioception and balance are recognized as intrinsic components in the etiology of PFPS, and research shows that PFPS patients have severe abnormalities in these domains when compared to healthy controls, particularly when performing dynamic tasks. The impaired balance and proprioception are hypothesized to result from altered neuromuscular control, decreased muscle strength, or changes in sensory feedback, which are crucial for maintaining stability and control over movements.The correlation between proprioceptive deficits and PFPS highlights the significance of including balance and proprioception-focused interventions in the PFPS treatment plan, as these can greatly enhance pain, function, and quality of life for those who are impacted. Addressing these deficits may not only improve symptoms associated with PFPS but also reduce the risk of further injury and enhance overall knee function.
To the best of the authors' knowledge, no previous study has specifically correlated knee JPS in a WB position (single-leg squat position) with PFPS. Thus, findings of this study might enhance the evidence-based clinical decisions made by the physical therapists regarding the management of PFPS, justifying for the patients the value of integrating proprioceptive and motor control training alongside traditional strengthening programs to improve functional outcomes. By addressing the neuromuscular factors linked to pain, rehabilitation strategies can become more precise and function-oriented, ultimately improving quality of life and physical performance.

pain intensity
時間枠：up to one day
|
nemerial pain rating scale will be used to assess pain intensity.
It comprises of 11 point ''horizontal scale'' of 0-10 in Arabic numerals anchored by the two ends, the left (0 indicating no pain at all) and right (10 indicating the worst ).

The Arabic version of the Kujala patellofemoral pain scoring system is a questionnaire to assess the patient with PFP.
It includes 13 points based on the following factors: presence of a limp, need for support, walking ability, stair climbing, squatting, running, jumping, prolonged sitting with knees flexed, pain, swelling, abnormal painful kneecap movement, atrophy of the thigh, and flexion deficiency.
Each question has multiple answers with points reflecting the severity of symptoms and level of functional limitation.
Each question is assigned a score of either up to 5 or 10, and the total score for the Kujala questionnaire is 100.
The higher the score, the better the function

knee joint position error (knee joint proprioception)
時間枠：up to one day
|
Digital-goniometer will be used to assess joint position error.the
digital-goniometer will be attached to the knee joint in the neutral knee position.
The fixed arm will be placed in parallel to an imaginary line between the head of the fibula and the lateral malleolus.
The movable arm will be placed in parallel to an imaginary line between the greater trochanter and the lateral condyle of the femur.
The digital-goniometer will be zeroed when the subject is standing motionless in the anatomic position.
To prevent slippage during knee joint motion, the end blocks will be adhered to the tested leg with double-sided adhesive tape and further secured in place with adhesive tape.
Digital-goniometer readings records knee joint angular displacements relative to zero
