Clinical Trial Summary

Patellofemoral pain syndrome (PFPS), also known as runner's knee, is a common knee condition characterized by pain and discomfort in the front of the knee, specifically around the patella (kneecap) and the surrounding area. The causes for anterior knee pain are multifactorial like overuse, muscle imbalances abnormal tracking of the patella, biomechanical issues, and improper alignment of the lower limbs. Activities that involve repetitive knee motion, such as running, jumping, squatting, or climbing stairs, can exacerbate the condition . The PFPS may cause aching pain around the front of the knee , especially when sitting for long periods, squatting, or climbing stairs, Pain worsens with activities that involve bending the knee, popping or grinding sensation in the knee and swelling or inflammation around the knee in some cases.


Description:

Patellofemoral pain syndrome (PFPS) leads to pain and restricted activities in athletes. There are many remedies used to tackle this problem like Physical therapy, Orthotics or shoe inserts, Patellar taping or bracing, RICE therapy, Nonsteroidal anti-inflammatory drugs (NSAIDs) and in some cases, corticosteroid injections are administered to reduce pain and inflammation. A randomized control trial will be conducted at Pakistan Sports Board Lahore through nonprobability convenience sampling technique on 38 patients which will be allocated through simple random sampling through sealed opaque enveloped into group A and group B. Group A will receive treatment with Clamshell exercises and group B will receive simple exercises for a period of six weeks. Side-lying clam exercises include lying down on one side on an exercise mat placing the head on arm and top leg/foot on lower leg/foot. Then lift the top leg towards ceiling and lower it again upto 10 to 20 times. Change sides and do 3 sets. Outcome measures such as range of motion will be measured by goniometer and pain by NPRS Scale, Visual analogue Scale and Kujala Patellofemoral pain score and the functional status will be measured with functional mobility test and physical performance testing. Patellar grind test for knee pain will also be performed at start and end to see the effectiveness of Clamshell exercise in athletes. Data will be analyzed using SPSS software version 21. After assessing normality of data, it will be decided either parametric or non-parametric test will be used within a group or between two groups. Effectiveness of clamshell exercises will be analyzed by comparison in individuals with PFPS.The significance of this study lies in evaluating the effectiveness of clamshell exercises of hip muscles on PFP. The clamshell exercise can be beneficial for individuals with PFPS as part of a comprehensive rehabilitation program as it primarily targets the hip abductor muscles and indirectly contributes to improving knee stability and addressing muscle imbalances that can affect PFPS. Based on the above stated literature review focusing on PFPS, its effects and remedies, we can conclude that athletes with PFPS shows signs of improvement when re-engaged in training activities. Also Clamshell exercises have wide impact to address muscles and knee problems, so there is a dire need to fill a research gap and study the impact of these exercises on PFPS with special focus on athletes facing the pain.

Outcome

Type Measure Description Time frame Safety issue
Primary Kujala patellar scale. (Pain ) diagnostic tool that aims to assess the severity of symptoms and physical limitations in patients with patellofemoral pain syndrome (PFPS). 13-item self-questionnaire that assesses to limitation physical activities and symptoms that are known to correlate with anterior knee pain syndrome.
This scle consist 0 - 100 score. Less than 90 shows physcial limitation or pain at patellar site. While 98 or 100 shows good knee with no pain or limitation.
4th day
Primary Goniometer. (ROM) Goniometer is used to measure the range of motion of joint. For knee joint, flexion ranges between 0-135º and extension ranges between 135-0º. 4th day
Primary Functional mobility test ( physical activity / function) Functional mobility test: Functional movement screen (FMS) is an evaluation tool for whom movement is a key part of exercise. FMS consists of 7 movement pattern and 3 three clearing tests assess pain for shoulder rotation motions, trunk extension, and trunk flexion. The FMS is scored on an ordinal scale, with 4 possible scores ranging from 0 to 3. 'Zero' refers if the individual has pain during any part of the movement. '1' represents that the person is unable to complete the movement pattern, '2' represents the ability to complete the movement with compensation and '3' refers that the person completes the movement without compensation 4th day
Secondary Manual muscle testing. Manual muscle testing is an assessment of muscle strength .The score of '0' represents no activity. '1' represents trace contractile activity but no resulting movement. '2' represents full ROM only in horizontal plane. '3' represents full ROM against the effect of gravity. '4' represents full ROM against gravity and test position is held under minimum resistance. '5' represents full ROM against gravity and test position is held under maximum resistance.
Grade 5 shows good muscle power.
4th week
Secondary Numeric pain rating scale. Numeric pain rating scale is 11-point scale ranges from "0" no pain to "10' worst imaginable pain. 4th week
Secondary Visual analogue scale Visual analogue scale measures pain that ranges across a continuum from none to an extreme amount of pain. VAS is usually a horizontal line, 100 mm in length, anchored by word descriptors at each end. The VAS score is determined by measuring in millimetres from the left hand end of the line to the point that the patient mark 4th week.
