Patellofemoral Pain SyndromeNCT04748692
Effectiveness of Exercise Therapy Versus Spinal Manual Therapy in Patients With PFPS
A study testing Local exercise therapy and Spinal manual therapy in people with Patellofemoral Pain Syndrome, run by Vrije Universiteit Brussel.
Trial summary
Preliminary results of a pilot study in The Bergman Clinic Naarden (NL) show that a local exercise therapy group may decrease pain by 30% on the visual analogue scale (VAS) after 6 weeks. A reduction of 50% on the VAS was realized in a spinal manual therapy group. Read more about this study

About this study
Official title: Effectiveness of Exercise Therapy Versus Spinal Manual Therapy in Patients With Patellofemoral Pain Syndrome: Medium Term Follow-up Results of a Randomised Controlled Trial
Preliminary results of a pilot study in The Bergman Clinic Naarden (NL) show that a local exercise therapy group may decrease pain by 30% on the visual analogue scale (VAS) after 6 weeks. A reduction of 50% on the VAS was realized in a spinal manual therapy group. Therefore, the aim of this study is to compare the effectiveness of local exercise therapy versus spinal manual therapy in patients with PFPS after 6 weeks of intervention and at 6 weeks of follow-up. To the knowledge of the authors, the clinical effectiveness of spinal manual manipulations on pain, function and strength has not been investigated in the medium term.
Read the detailed description
Interventions
The local exercise therapy group will focus on strengthening knee and hip muscles three times a week for 6 weeks. Once a week, patients will train with the support of a physiotherapist. The physiotherapist gradually increases the intensity of the exercises improving muscle endurance. The exercises will be supplemented with mobilisations of the patellofemoral joint. Twice a week, patients train at home following a prescribed exercise program writing down their work-out in an exercise journal.
The spinal manual therapy group will be treated one a week for 6 weeks. Before the first intervention an experienced manual therapist performed a clinical examination of the lower back, SIJ, hip and knee. Anatomical maps showing innervation areas of spinal nerve roots will be used to explain the regional interdependence model in the treatment of anterior knee pain. Manual therapy treatment will include manipulations of the thoracolumbar (T12-L3) region or SIJ as well as hip joint. Manipulation will be conducted if a restriction of range of motion will be found in any of the regions. Patients will also be asked to do home exercises focusing on mobilizing the thoracolumbar region and to write down their performance in an exercise journal.
The allocation of the patients to their treatment group will be concealed from the researcher that assesses the outcome measures.
Outcome measures The following baseline characteristics will be self-reported: age (in years), weight (in kg), height (in cm), duration of symptoms (in months), weekly participation in sport (yes/no), previously receiving exercise therapy treatment for the knee (yes/no). Patellofemoral chondral lesions will be graded using the Kellgren and Lawrence system for classification of osteoarthritis (grade 0 = definite absence of X-ray changes of osteoarthritis, grade 1 = doubtful joint space narrowing and possible osteophytic lipping, grade 2 = definite osteophytes and possible joint space narrowing).
Knee pain, functionality and force will be measured using validated measurement instruments. Pain and functionality will be our primary outcomes. Maximum, minimum and current pain intensity will be indicated on a 0-100 mm VAS line. Functionality will be measured using the Dutch version of the anterior knee pain scale (AKPS). The AKPS questionnaire consists of 13 items assessing subjective symptoms and functional limitations totalling a maximum score of 100. Our secondary outcome, maximum voluntary peak force (MVPF) of the quadriceps, will be measured using a Biodex system 3 isokinetic dynamometer (Biodex Medical Systems, Inc., Shirley, NY, USA). This system has shown sufficient reliability and validity for position, torque and velocity measurements in clinical and research settings. Patients will be assessed before intervention (=baseline), at 6 weeks (=immediately after the last intervention) and at 12 weeks (=6 weeks after the last intervention).

Maximum voluntary peak force (MVPF) of the quadriceps, will be measured using a Biodex system 3 isokinetic dynamometer (Biodex Medical Systems, Inc., Shirley, NY, USA). This system has shown sufficient reliability and validity for position, torque and velocity measurements in clinical and research settings.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Preliminary results of a pilot study in The Bergman Clinic Naarden (NL) show that a local exercise therapy group may decrease pain by 30% on the visual analogue scale (VAS) after 6 weeks. A reduction of 50% on the VAS was realized in a spinal manual therapy group. Therefore, the aim of this study is to compare the effectiveness of local exercise therapy versus spinal manual therapy in patients with PFPS after 6 weeks of intervention and at 6 weeks of follow-up. To the knowledge of the authors, the clinical effectiveness of spinal manual manipulations on pain, function and strength has not been investigated in the medium term.

Who may be eligible to take part?
The sponsor lists 3 inclusion and 11 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 10 May 2021. Status can change between updates, so confirm with the study contact before making plans.
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?
Visual analogue scale (time frame: before the first intervention (at baseline)). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04748692, which also lists 9 linked publications.
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 10 May 2021.
