About this study
Official title: Effect of Proximal Stabilization on Recruitment of the Core & Vasti in Patients With Patellofemoral Arthritis as They Descend Stairs
Purpose: to investigate the effect of proximal stability on PF OA. Methods: Thirty patients with PF OA will be recruited. Patients will be randomly assigned into two groups, group A and group B . Patients in both groups will receive a traditional physical therapy treatment, but group (B) will receive additional proximal stability exercise. All patients will be evaluated for muscular recruitment strategies (onset and duration) of multifidus, transversus abdominus (TrA), gluteus medius (GM), and vasti measured by quantitative Electromyography during stair descent. pre and post-treatment.
Read the detailed description
: A) Procedures for evaluation: The practical section of the studywill be undertaken in 6 weeks (2 sessions a week). Measurement will be taken before the start of treatment program then after the end of 6 weeks treatment program. Investigators will collect the EMG activity of VMO, VL, GM, multifidus, and TrA using bipolar Ag-AgCl disposable surface electrodes (Better signal solution medical supply Co., limited, Zhongshan, China) and eight channels highresolution wireless bio amplifier (WBA) system (Biomation, Almonte, Canada). Electromyographic data will be sampled at 1000 Hz and bandpass filtered at 50-200 Hz. For each muscle, three electrodes will be used; two electrodes will be placed ~ 30 mm apart in the direction of the muscle fibers and a ground electrode will be placed over the closest bony prominence. Before placement of the electrodes, the subject's skin will be cleaned with alcohol to reduce impedance and excess hair will be removed to eliminate shifting of the electrodes if needed. The stairstepping task will consist of descending 2 steps Before data acquisition, participants will be asked to perform one practice trial of stair descent to get familiarized with the task. Then the participants will perform three test trials with thirty seconds of rest after each trial to prevent fatigue. The raw data will be stored on a personal computer for analysis with a custom program in Matlab . Investigators will use a mean of data in three trials for analysis.
- Procedures for treatment: All patients will receive a traditional physical therapy program in the form of TENS , stretching hamstring, quadriceps and calf muscles
- Group (A) Patients in this group will receive a traditional therapeutic knee rehabilitation program in the form of mini-squatting exercise (up to 45 degrees knee flexion measured by a universal goniometer) , strengthening of hip abductors and external rotators using clamshell exercise . No emphasis will be placed on stabilizing the core musculature before initiating any of those exercises.
- Group (B) Patients in this group will receive the same program as group (A) plus proximal stability exercise and the principles of proximal stability will be explained to patients before initiation of treatment and patients will be asked to comply with these principles during exercise. These principles include learning how to activate transversus abdominus by abdominal bracing without allowing pelvis tilting and ensure neutral spine and diaphragmatic breathing during exercise.

Questions about this trial
What is this clinical trial studying?
A study testing traditional knee rehabilitation program and proximal stabilization in people with Chondromalacia Patellae, run by Cairo University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Jun 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The change of EMG onset of multifidus (time frame: baseline and six weeks). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Jun 2024; AzTrials last refreshed its copy on 7 Nov 2026.
