Effect of Gluteus Maximus Fatigue on Hip and Knee Inter-joint Coordination
Overview
Tab Title Description
Study type
InterventionalDescribes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.
- Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
- Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

About this study
The purpose of this study is to examine whether inter-joint hip and knee coordination differs during single-limb squat movements following a fatiguing protocol of the gluteus maximus.
Participation eligibility
Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.
Inclusion Criteria:
- Active, healthy, young adults capable of performing single-leg tasks and free from current lower extremity or back pain.
Exclusion Criteria:
- Since testing involves fatigue-inducing isometric contractions of the hip and spinal extensors, subjects with a resting blood pressure greater than 140/90 mmHg or a history of low back pain within 6 months of testing will be excluded.
- Secondary to the nature of the single-limb squat exercise comprising the primary test in the study, subjects with patellofemoral pain syndrome symptoms (anterior/peripatellar knee pain > 2 on the 11-point pain intensity scale when walking down stairs, squatting, or after prolonged sitting) within 6 months prior to testing or subjects with history of traumatic knee injury (ligament tear, patella dislocation, knee surgery) will be excluded from participating.
- Subjects will also be excluded from participating if there is any suspicion of ligamentous injury or meniscal damage. Signs and symptoms of knee conditions will be screened with a pre-enrollment survey and pre-enrollment testing.
- Study personnel will screen subjects for ligamentous instability by performing the Lachman test to assess anterior cruciate ligament integrity, the posterior drawer test to assess posterior cruciate ligament integrity, and valgus and varus thrust tests to assess medial and lateral collateral ligament integrity, respectively.
- Study personnel will screen subjects for meniscus pathology by palpating for joint line tenderness and for patella instability by performing a patella apprehension test.
