About this study

Official title: Therapeutic Effect of Two Muscle Strengthening Programs in Patients With Patellofemoral Pain Syndrome From Bogota, Colombia. Experimental Study, Clinical Controlled Trial

Introduction: The patellofemoral pain syndrome (SPF) is one of the most frequent pathologies generated by the knee joint. Conservative treatment with physiotherapy exercises reduces pain and improves functional capacity in the short and medium term. The purpose of this study was to evaluate the therapeutic effect of combining a program of muscle strengthening exercises for the core, hip and knee on anterior knee pain in non-athletic patients with SPF. Materials and methods: Randomized controlled trial clinical trial, designed to evaluate the effect of two muscle strengthening programs in people with SPF (Group A: exercises for core, hip and knee, Group B: exercises for hip and knee), during eight weeks of intervention in people between 15 and 40 years of age, with a clinical diagnosis of SPF, with a level of mild to moderate physical activity. The Kujala test was used to measure pain and quality of life.

Read the detailed description

Experimental study: controlled clinical trial, designed to evaluate the effect of two muscle strengthening programs in people with patellofemoral pain syndrome.

Young adults between 15 and 40 years old, with clinical diagnosis of patellofemoral pain syndrome (by means of Computerized Axial Tomography and medical concept of a specialist Orthopedist in knee), in the last three years, non-athletes with a level of physical activity between mild and moderate, affiliated to the health care institution CAFAM (Caja de Compensación Familiar is a compensation fund of Colombia that has pharmacies, hotels, Convention Center, Recreation Club, School, among others and offers Subsidy Services, Credits, Insurance, Tourism, Health, Education, Housing).

All the procedures developed within the study had as a reference the standards of good clinical practice and ethical principles for medical research in humans. The participants signed the informed consent where they accepted their participation in the present study.

The participants were randomized with the SNOSE (sequentially numbered, opaque sealed envelopes) method to two protocols of muscular strengthening (Group A: Exercises for core, hip and knee and Group B: Exercises for Hip and Knee).

  • Strengthening programOther

    Both protocols lasted eight (8) weeks, the anatomical conditioning phase was carried out in two weeks of intervention, followed by 4 weeks of strengthening or strength increase and two additional weeks as a final or maintenance phase, at the end of which performed the final evaluations to identify if there were differences in the groups after the physiotherapeutic intervention.

What is being measured

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

  1. Assessment of Change in Pain and Function Before and After Treatment With Kujala´s Test: Presented as Percentages and 95% Confidence Interval.

    The Kujala patellofemoral pain scale, is an assessment tool developed to assesses pain and function in patients with disorders of the patellofemoral joint and consists of 13 questions, each with three to five response options, scored from 0 to 5, or 0 to 10, depending on the question. The lowest possible total value is 0 and corresponds to patients who are in a worse functional health condition. The highest possible total value is 100, for those that do not have any alteration and are in optimal condition. The results below, are presented as percentages and 95% confidence interval.

    Measured: The next table shows the distribution of the 13 domains of the Kujala´Test by intervention group at baseline (Time point 1, one day before intervention). "Assessed at baseline and after treatment, only baseline pre-specified to be reported".

  2. Assessment of Change in Pain With Visual Analogue Scale

    Visual Analogue Scale (VAS) is a numeric scale from 0 to 10 to measure pain (been 0 no pain and 10 worse pain).

    Measured: The pain assessment will be done at two different time points (Time point 1 is baseline, one day before intervention and Time point 2 is 8 weeks post-intervention)

Secondary outcomes (5)
  1. Change in Patellofemoral Misalignment With Q Angle´s Exam

    We measured the Q angle (degrees) between the border of the anterosuperior iliac spine, the center of the patella and the center of the tibia.

    the data result, shows the median values, and the interquartile range (IR) with a Delta change between measure number 1 and number 2.

    Measured: The Q angle assessment will be done at two different time points (Time point 1 is baseline, one day before intervention and Time point 2 is 8 weeks post-intervention).

  2. Change in Core Strength With McGill´s Exam

    The protocol consists of 3 tests that measure all aspects of torso strength via isometric muscle endurance 1.Trunk flexor test, 2.Trunk extensor test 3. Lateral musculature test (rigth and left side). t is a timed test involving a static, isometric contraction, until the individual exhibits fatigue and can no longer hold the assumed position. The goal of the test is to hold each position for as long as possible.

    Measured: The Core strength assessment will be done at two different time points (Time point 1 is baseline, one day before intervention and Time point 2 is 8 weeks post-intervention)

  3. Change in Quadriceps and Gluteus Strength With Squat´s Test

    Squat Test is a field test, easy and simple to assess the Gluteus and quadriceps muscles strength.

    Measured: Quadriceps and gluteus Strength assessment will be done at two different time points (Time point 1 is baseline, one day before intervention and Time point 2 is 8 weeks post-intervention)

  4. Change in Static Balance With Single Leg Stance

    This test is used to evaluate the control of postural and static balance with the eyes open and closed in seconds. (if the participant does not complete the 45 seconds framework is thought to be lacking of equilibrium).

    Measured: Static Balance assesment will be done at two different time points (Time point 1 is baseline, one day before intervention and Time point 2 is 8 weeks post-intervention)

  5. Change in the Total Amount (Work, Transport, Home and Recreation) of Physical Activity Reported in Minutes and Measured With The International Physical Activity Questionnaire-Long Form

    The amount of physical activity places patients in 1 to 3 categories:

    1. Low/inactive: do not meet criteria for categories 2 or 3. 2. Moderate: meet 1 the following: a. 3 or more days with at least 20 minutes of vigorous activity b. 5 or more days with at least 30 minutes of moderate-intensity activity or walking. c. 5 or more days with any combination of walking, moderate-intensity, or vigorous intensity activities with at least 600 MET-min/week. 3. High: meet 1 of the following: a. 3 or more days of vigorous-intensity activity and at least 1500 MET-min/week. b. 7 days of any combination of walking moderate-intensity, or vigorous intensity activities with at least 3000 MET-min/week.

    We decided to add the time in minutes for each category of the IPAQ (work, transport, home and recreation), to obtain a more objective calculation, and to be able to make comparisons between the two different time points.

    Measured: Physical Activity will be measured at two different time points (Time point 1 is baseline, one day before intervention and Time point 2 is 8 weeks post-intervention)
