Joint Pain | Context Effects in Exercise Therapy for Knee and/or Hip Pain

Joint Pain research study

What is the primary objective of this study?

The study is designed to investigate the effect of physical surroundings on the effect of exercise therapy for knee and hip pain.

Who is eligible to participate?

Inclusion Criteria: - Age: 35 years or older - Self-report of knee and/or hip pain within the last 3 months. - Willing and able to attend exercise therapy at the University of Southern Denmark, Odense M twice weekly. Exclusion Criteria: - Co-morbidities or contraindication prohibiting to participation in exercise therapy. - Unable to fill-out questionnaires, or to speak, read or understand Danish. - Already participating in exercise therapy*, having had surgery to the hip/knee within the last 3 months or on waiting list for joint surgery within the coming 6 months. (*defined as supervised exercise program by physiotherapist, systematic strength training etc. with duration of 6 weeks or more)

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Other:Contextually enhanced physical surroundings of exerciseDifferent physical surroundings of exercise may affects the patients differently and consequently influence the effect of exercise. The exercise rooms are different from each other on parameters such as source of lighting, acoustics, materials and decorations. The differences with the physical surroundings of exercise is the primary intervention for this study.

Other:Neuromuscular exerciseThe neuromuscular exercise program is the same across the two exercise groups. Consequently, this intervention is not the primary intervention of this study. The exercise program is based on the previously reported NEMEX program designed for patients with hip or knee osteoarthritis, originally published by Ageberg et al, 2010 in BMCMusculoskeletal Disorders.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

Exercise in standard roomIntervention: Exercise Patients exercise in standard physical surroundings. The room is marked by years of use. The room is placed in the basement, has artificial lighting, poor acoustics and bare concrete walls.

Exercise in a contexually enhanced roomIntervention: Exercise + contextually enhanced physical surroundings Patients exercise in a contextually enhanced room. The room has both artificial lighting and daylight, view of a recreational park, better acoustics, decorations among other factors, which may cause or enhance the context effect.

Waiting listPatients on waiting list are included, baseline tested and placed on a waiting-list for a 8 week period and tested at 8 weeks follow-up. The group is representative of the natural cause of disease.
