About this study

The present study is the first one to compare the effectiveness of adding (FNG) versus (LPM ) to conventional exercise therapy in pain, knee functional abilities, hip extension ROM and femoral nerve electrophysiological studies among those with PFPS.

This study will be conducted at the outpatient clinic of faculty of Physical Therapy, Cairo University Sixty patients with unilateral PFPS referred from an orthopaedic surgeon for selection criteria, will be included in the study. Measurement procedures, treatment procedures, and the study's goal will be explained to each patient before participation in the study. After being informed about the study aim, they will be asked to sign an informed consent for their approval to participate

The study patients will be randomly assigned into three groups

  • Group A: control group will receive conventional hip-knee focused exercises only.
  • Group B: study group will receive FNG in addition to the same conventional hip-knee focused exercises.
  • Group C: study group will receive LPM in addition to the same hip-knee focused exercises All patients will receive 2 sessions/week for 6 weeks (12 sessions). They will be instructed to do the conventional hip-knee exercises at least two times per day. Each session will last for 20-30 minutes.

Patients diagnosed with unilateral PFPS will be screened based on the following inclusion and exclusion criteria A sample size of 60 participants will be appropriate. The computations will done using G* Power version 3.1.9.2 (Franz Faul, Uni Kiel, Germany) Randomization and blinding will be accomplished through using selected types such as A 1:1:1 allocation ratio will be employed for randomization using the website http://www.randomization.com. Blinding will be done on the patients, assessor, and statistician. All patients will be blinded to the task assigned to their group by ensuring they will be unaware of the exercises that the other group will complete. To maintain blinding, the intervention sessions will be administered to each member of the treatment group separately. Before the trial began, an impartial research assistant who will not participating in the study and he will keep the allocation sequence a secret. It will be kept hidden in opaque, sealed envelopes that will not be opened until baseline data will be collected

Outcome Measures:

  1. Knee Pain
  2. Knee function
  3. Electro-physiological studies including (sensory nerve conduction velocity and distal latency).
  4. Sagittal plane hip extension range of motion as a reference for femoral nerve mechanosensitivity changes - The outcomes will be measured at baseline (pre-test) and after 12sessions (after 6 weeks) (post-test) Then patients will receive 4 types of assessments step's including pain assessment using NRS then knee function assessment using arabic version of AKPS then hip extension ROM assessment using digital goniometer after that the electrophysiological studies including femoral nerve will be conducted using the computerized electromyography device for measuring selective parameters such nerve conduction velocity and its amplitude along with onset and peak latency.

Then Intervention will be completed as follow : All patients will receive two treatment session per week for six weeks (6 sessions), supervised by primary investigator. Separate sessions will be given to each treatment group's members. Each session lasted for 15-30 minutes. The three groups will receive hip-knee focused exercises approved by the clinical practice guidelines linked to the international classification of functioning, disability, and health from the Academy of Orthopedic Physical Therapy of the American Physical Therapy Association which consisted of hamstring/calf and ilio-tibial band stretching and hip/knee strengthening exercises. group B will receive FNG addition to hip-knee focused exercises. group C will receive LPM in addition to hip-knee focused exercise. The session of the control group will start with stretching exercises followed by strengthening exercises. On the other hand, the study group session will start with stretching exercises followed by femoral nerve glide and/or LPM then strengthening ex.

The study has a 3 null hypothesis

  1. There will be no statistically significant effects of adding FNG to conventional exercises in patients with PFPS on:
  2. Knee pain. B) Functional abilities. C) Hip extension ROM. D) Electrophysiological study (NCV and distal latency).
  3. There will be no statistically significant effects of adding LPM to conventional exercises in patients with PFPS on:
  4. Knee pain. B) Functional abilities. C) Hip extension ROM. D) Electrophysiological study (NCV and distal latency).
  5. There will be no statistically significant difference between adding FNG versus LPM to conventional exercises in patients with PFPS on:
  6. Knee pain. B) Functional abilities.C) Hip extension ROM. D) Electrophysiological study (NCV and distal latency).
Being tested
Femoral nerve gliding technique, Lumbopelvic manipulation, Exercises

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Femoral nerve gliding techniqueOther

    Also called Neural mobilization

    The patients only of group B will be positioned on their asymptomatic side with their body in full flexion. The researcher then extended the patient's hip while keeping the knee flexed, holding the position for 2 seconds. when the patient reports soreness or pain. This mobilization technique will be repeated for 3 sets of 10 repetitions per session, with a total of 12 sessions over 6 wks

  • Lumbopelvic manipulationOther

    Patients if group C will receive lumbopelvic manipulation, which consists of applying rotational glide forces to the ipsilateral lumbopelvic region of the involved knee. Patients will lay supine and the therapist stood contralateral to the side which was to be manipulated. They will passively move onto their side, toward the side to be manipulated, and then interlocked their fingers behind their head. The researcher will passively rotate the patient, and then delivered a quick thrust to the anterior superior iliac spine in a posterior and inferior direction. Each patient received a maximum of two manipulations on the same side as the symptomatic knee

  • ExercisesOther

    For control group (A) will start with the stretching exercises then starting with the hip extensors, then the hip abductors, and finally the hip external rotators. Next, knee strengthening exercises will be carried out, beginning with mini wall squats using a theraband around the distal thigh, followed by terminal knee extension exercise from a standing position, and finishing with seated knee extension exercise from 90° to 45° knee flexion.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. knee pain intensity

    Pain intensity will be measured by the Arabic version of the Numeric Rating Scale during the last 24 hours. The minimum is zero and the maximum highest pain score is 10. The assessment will be done at baseline and after the last treatment session after 6 weeks

    Measured: 6 weeks

  2. functional disability

    functional disability will be measured by the Arabic version of Kujala anterior knee pain questionnaire; higher scores means higher disability

    Measured: 6 weeks

Secondary outcomes (2)
  1. femoral nerve conduction velocity by surface electromyography (sEMG).

    Femoral nerve conduction velocity and its distal latency will be measured by surface electromyography (sEMG).

    Measured: 6 weeks

  2. Hip extension Rang of motion

    Hip extension ROM will be assessed before and after the treatment in all groups using digital goniometer

    Measured: 6 weeks
