Hip PainNCT04720846
Categorized PT for Non-arthritic Hip and Groin Pain
A study testing Matrix-based physical therapy and Standard-of-care physical therapy in people with Hip Pain and Groin Pain, run by Hospital for Special Surgery, New York at 1 site in United States.
Trial summary
There is currently limited literature on a categorized physical therapy protocol for management of hip pain. Only a handful of studies have looked at the treatment of osteoarthritis of the hip with a standardized physical therapy treatment, primarily looking at manual therapy versus exercise therapy protocols.

About this study
Official title: Assessment of a Categorized Physical Therapy Protocol for Non-arthritic Hip and Groin Pain: a Randomized Controlled Study
There is currently limited literature on a categorized physical therapy protocol for management of hip pain. Only a handful of studies have looked at the treatment of osteoarthritis of the hip with a standardized physical therapy treatment, primarily looking at manual therapy versus exercise therapy protocols. However, there are no studies observing the effect of a standardized physical therapy program on patients presenting with non-arthritic hip and groin pain. Based on the gap in the literature, this study will aim to assess the effect of matrix-based standard of care therapy in patients presenting with non-arthritic hip and groin pain.
- Conditions
- Hip Pain, Groin Pain
- Being tested
- Matrix-based physical therapy, Standard-of-care physical therapy
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Matrix-based physical therapyOther
Matrix-based physical therapy will be physical therapy that is based on the matrix categorization of the patient (stiff vs. mobile hips, weak vs. strong hips) and involves instructions on the amount of time that should be spent doing stretching and strengthening therapy.
Standard-of-care physical therapyOther
Physical therapy that is being conducted as standard-of-care
| Study group | Role | What they receive |
|---|---|---|
| Control | Active comparator | Patients will receive standard-of-care physical therapy. Receives: Other: Standard-of-care physical therapy |
| Matrix-Based PT | Experimental | Patients will receive matrix-based physical therapy, in addition to standard-of-care physical therapy. Receives: Other: Matrix-based physical therapy; Other: Standard-of-care physical therapy |
What is being measured
The primary outcome is the main question the study is designed to answer.
iHOT-12 (International Hip Outcome Tool-12)
iHOT-12 is used to assess quality of life in patients with hip disorders. Scores range from 0 to 100; a higher score represents a better quality of life.
Measured: Up to 6 months
Secondary outcomes (2)
NRS (numerical rating scale) pain
NRS pain will be used to assess pain. Scores range from 0-10, with 10 representing the worst pain imaginable.
Measured: Up to 6 months
Home exercise completion
This will be defined as the number of times patients completed their home exercises during the previous week.
Measured: Up to 6 months
