Does Patellofemoral Pain Syndrome (PFPS) Correlate with Gluteus maximus endurance?
Background: Patellofemoral pain syndrome (PFPS) is a very common knee injury accounting
for many patients who present with orthopaedic injuries. There are several treatment methods for
PFPS which are employed based on the varied underlying issues that could result in anterior
knee pain. Among these methods is the need for strength and power in the gluteus maximus
(GMax) muscle group to aid in the reduction or onset of PFPS. Existing research does not speak
much about the importance of GMax endurance and how it may impact the onset of PFPS.
Purpose: This study was designed to determine whether PFPS is linked to gluteus maximus
endurance.
Ethical Considerations: Data that are collected will be deidentified, stored and secured on a
password-protected computer accessed only by the research team. There is minimal risk to
participants and any pain arising will be managed and treated on site.
Approval from Ethics Committee
Location and time frame: Testing will be done on one of the basketball courts at the
Barbados Aquatic Centre located at Wildey Road, Bridgetown, Christ Church, Barbados
The Aquatic Centre is a public access facility. The proposed time frame to complete the
study will be from the 1st of April 2025 to June the 28th 2025.
Objectives
The present study has three objectives.
1. To determine the prevalence of PFPS (anterior Knee pain) in long distance
runners
2. To determine the endurance of GMax (gluteus maximus) muscle in long distance
runners using static squat test performance
3. To determine the relationship between patellofemoral pain and static squat test
performance levels in long distance runners with and without patellofemoral pain
syndrome
Inclusion Criteria
To be included in the study, participants should have the following characteristics:
● Participants should be a man or woman between the ages of 18 and 40 years old.
● Recreational runner (i.e., running greater than 15 km per week; Dierks et al., 2008).
Exclusion Criteria
Persons will be excluded if:
● They had previous knee surgery; this is done to ensure that pain is not associated with
other pathologies.
