About this study
Official title: Patients With Longstanding HIP and Groin Pain Referred to Orthopedic Care: Effectiveness of Education and exerciSe ThERapy (HIPSTER)
Longstanding hip and groin pain (LHGP) is a common and debilitating problem in young to middle aged individuals. These patients often get referred to orthopedic departments. Consensus statements on the management of these patients commonly recommend a physical therapist-led intervention as the first line intervention. However, the optimal content and delivery of this intervention is currently unknown. In this study we will compare the effectiveness of usual care (unstructured physical therapist-led intervention) to a semi-structured, progressive individualized physical therapist-led intervention on hip-related quality of life in people with longstanding hip and groin pain referred to an orthopedic department.
Read the detailed description
This study is a parallel-group randomized controlled trial, comparing the effectiveness of patient education and exercise therapy to usual care on hip-related quality of life in people with longstanding hip and groin pain referred to an orthopedic department. Participants will be allocated in a 1:1 ratio to either usual care (orthopedic diagnostic pathway and recommendation of physical therapy) or the HIPSTER model, a semi-structured, progressive and individualized physical therapist-led intervention focusing on patient education and exercise therapy.
The primary aim of this trial is to determine the effectiveness of a structured physical therapist-led treatment model (HIPSTER) compared to usual care on hip-related quality of life. The primary hypothesis is that the HIPSTER model will be superior to usual care by at least 10 points between group change in improving self-reported hip-related function and quality of life, measured by iHOT-33.
Secondary aims include comparing group differences in achievement of patient acceptable symptom state (PASS) at 4 months and to compare between group changes in self-reported physical activity, pain self-efficacy, and pain catastrophizing, and physical performance tests regarding ROM, muscle force production, hop performance and balance between the HIPSTER group and usual care (baseline to 4 months), as well as cost-effectiveness of the interventions.
A full trial protocol will be published. The primary analysis will be performed using a t-test, according to intention-to-treat principles. A per protocol analysis will also be conducted, comparing participants who completed usual care or the HIPSTER model with high fidelity. Relevant parametric and non-parametric tests will be performed to compare change in physical performance tests and secondary PROMs.
A subgroup of patients will be included in qualitative study, using a semi-structured interview to capture the experience of participating in the HIPSTER intervention. A subgroup of patients will also answer additional questions regarding psychosocial factors related to hip and groin pain.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Usual careOther
Usual care at the orthopedic department consists of a clinical examination, radiological imaging, and a diagnostic injection. A recommendation to get physical therapy treatment in primary care will be provided, but this intervention will not be controlled by the investigators in any capacity.
HIPSTEROther
Patients will be provided with usual care at the orthopedic department, which consists of a clinical examination, radiological imaging, and a diagnostic injection.
In addition, participants in this group will be referred to physical therapists trained in administering a semi-structured, individualized, progressive treatment. This 16-week intervention targets known physical and psychological impairments in people with long-standing hip and groin pain, using exercise therapy and patient education.
| Study group | Role | What they receive |
|---|---|---|
| Usual care | Active comparator | Participants in this group will undergo usual care at the orthopedic department and will get a recommendation for physical therapist-led treatment in primary care. Receives: Other: Usual care |
| HIPSTER | Experimental | Participants in this group will undergo usual care at the orthopedic department and will also receive a semi-structured intervention according to the HIPSTER treatment model. Receives: Other: HIPSTER |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in iHOT-33 scores at 4 months
iHOT-33 is a 33 question self-reported outcome scale, measuring hip-related quality of life. This outcome measure has been validated and translated to Swedish. The scores are summed on a 0 (worst)-100 (best) scale.
Measured: The primary outcome will be collected at baseline and at the primary end-point (4 months after baseline).
Secondary outcomes (23)
Change in iHOT-33 scores at 1, 2 and 5 years
iHOT-33 is a 33 question self-reported outcome scale, measuring hip-related quality of life. This outcome measure has been validated and translated to Swedish. The scores are summed on a 0 (worst)-100 (best) scale.
Measured: This outcome will be collected at baseline and 1,2 and 5 years after baseline.
Patient acceptable symptom state (PASS)
The patient acceptable symptom state (PASS) will be collected using a dichotomized question ("Taking into account your hip and groin function and pain, and how it affects your daily life, including your ability to participate in sport and social activities, do you consider that your current state is acceptable if it remained like that for the rest of your life?").
Measured: This outcome will be collected at the primary endpoint (4 months after baseline). In addition it will also be collected at 1,2 and 5 years after baseline.
Treatment failure
Treatment failure will be collected using a dichotomized question "Do you consider your current state so unsatisfactory that you think your treatment has failed?".
Measured: This outcome will be collected at the primary endpoint (4 months after baseline). In addition it will also be collected at 1,2 and 5 years after baseline.
Perceived symptom improvement
Perceived symptom improvement will be collected using a 7-point Global rating of change (GROC) scale, ranging from -3 (a lot worse), to +3 (a lot better).
Measured: This outcome will be collected at the primary endpoint (4 months after baseline). In addition it will also be collected at 1 year after baseline.
Patient desire and beliefs regarding surgical intervention
Patient desire and beliefs regarding surgical intervention will be collected using two dichotomized questions; "Do you want to undergo surgery?" and "Do you believe surgery is needed for you to get better?".
Measured: This outcome will be collected at baseline and at the primary endpoint (4 months after baseline). In addition it will also be collected at 1 year after baseline.
Physical activity
Physical activity and return to sport/exercise will be collected using questions based on the Swedish National Board of Health and Welfare (Socialstyrelsen) physical activity screening, a self-reported measure of minutes spent doing strenuous and everyday activities.
Measured: This outcome will be collected at baseline and at the primary endpoint (4 months after baseline). In addition it will also be collected at 1 year after baseline.
Pain catastrophizing
Pain catastrophizing will be measured with the Pain Catastrophizing Scale (PCS), a valid patient-reported outcome with 13 items. It is scored 0 to 52, with higher values indicating higher degrees of catastrophizing.
Measured: This outcome will be collected at baseline and at the primary endpoint (4 months after baseline). In addition it will also be collected at 1 year after baseline.
Pain self-efficacy
Pain-related self-efficacy will be collected with the short-form Pain Self-efficacy Questionnaire (PSEQ-2), a commonly used measure of self-efficacy in musculoskeletal pain. PSEQ-2 consists of 2 questions. It is scored 0 to 12, with higher score indicating a greater degree of pain self-efficacy.
Measured: This outcome will be collected at baseline and at the primary endpoint (4 months after baseline). In addition it will also be collected at 1 year after baseline.
Health related quality of life
Generic health-related quality of life will be measured using EQ5D. It is scored from 0 to 1, where 1 corresponds to perfect health, and is available in Swedish.
Measured: This outcome will be collected at baseline and at the primary endpoint (4 months after baseline). In addition it will also be collected at 1 year after baseline.
Employment status
Employment status will be measured using a Likert scale, from unemployed, student, part time work, full time work or retired.
Measured: This outcome will be collected at baseline and at the primary endpoint (4 months after baseline). In addition it will also be collected at 1 year after baseline.
Other non-operative treatment
Self-reported documentation of other non-operative treatments, like medications, injections etc.
Measured: This data will be collected at baseline, 4 months and 1 year.
Usual care content
Any physical therapist-led intervention in the usual care group will be collected using self-reported questions regarding volume (number of sessions), content (overall focus of intervention) and adherence (patient compliance to prescribed intervention).
Measured: This outcome will be collected from the usual care group, after the primary end-point at 4 months.
Adherence
Adherence will be collected by reporting of the number of supervised visits to a treating physical therapist as well as percentage of prescribed exercises completed, and any educational resources accessed.
Measured: Adherence will be collected weekly from baseline until primary end-point (4 months) in the HIPSTER group. In the usual care group adherence will be collected at primary end-point (4 months).
Hip range of motion
Hip range of motion (in degrees) will be measured with a digital inclinometer in internal rotation in 90° of hip flexion and zero° flexion.
Measured: This outcome will be collected at baseline and at the primary endpoint (4 months after baseline).
Isometric hip muscle force production
Isometric hip muscle force production will be measured (in Newton and nm/kg) with a belt-fixated handheld dynamometer for hip adduction, flexion and hip extension.
Measured: This outcome will be collected at baseline and at the primary endpoint (4 months after baseline).
