Plain English Summary

Background and study aims
Hand osteoarthritis is one of the most common rheumatic diseases, concerning 60-70% of the population over 65 years. The small finger joints are affected in particular. This causes pain and swelling. In addition, people often have problems using their hands, which makes everyday activities more difficult.
There are drug and non-drug treatments for hand osteoarthritis. Treatments are provided by various health professionals, such as rheumatologists, nurses, occupational therapists and physiotherapists.
The aim of this study is to assess how well an ‘interdisciplinary’ intervention works (when the various health professionals work together and learn from one another).

Who can participate?
Patients with hand osteoarthritis.

What does the study involve?
Participants will be randomly allocated to one of two groups: standard treatment group or interdisciplinary intervention group.
The interdisciplinary intervention group will have access to: exercise programs, products and tools (called assistive devices) that can make life with hand osteoarthritis easier, splints, weight reduction advice, information about exercise, self-management, when to consider surgery, pain and pain management, and telephone follow-up.

What are the possible benefits and risks of participating?
Participants will have consultations with different health professionals.
There are no risks involved and participants can contact health professionals immediately and directly in case of adverse events.

Where is the study run from?
The study will be done by researchers of the Medical University of Vienna/ Department for Rheumatology (Austria). Participant consultations will take place there.

When is the study starting and how long is it expected to run for?
May 2012 to May 2014.

Who is funding the project?
Physio Austria – Professional Association of Physiotherapists (Austria)
Ergo Austria – Professional Association of Occupational Therapists (Austria)
FH Campus Wien, University of Applied Sciences (Austria)
Medical University Vienna, Department of Rheumatology (Austria)

Hand Osteoarthritis


Patients will be randomised into two groups. Each group receives an intervention, either the standard treatment in agreement with the rheumatologist or the interdisciplinary intervention. Patients randomised into the standard treatment group will be given the offer to receive the interdisciplinary intervention after two months if they wish to.

Interdisciplinary intervention includes:
1. Exercise program
2. Information about physical activity
3. Assistive devices for daily living
4. Splints if needed
5. Weight reduction if needed
6. Information for self management to increase self-efficacy
7. Physical methods
8. Information about when to consider surgery
9. Information about pain and pain management
10. Telephone follow-up

Drug names

Primary outcome measure

Grip strength measured using a vigorimeter at baseline and two months later

Secondary outcome measures

1. Hand function measured by a test (sub-test of the Jebsen-Taylor-Hand-Function-Test) and a self-report questionnaire (AUSCAN)
2. Self-reported assessment of pain and satisfaction of patients with their health care and health status (on a 11-point Likert scale)

Measured at baseline and two months later.

Participant inclusion criteria

1. Patients meeting the American College of Rheumatology (ACR) criteria for hand OA
2. In order not to exclude patients with hand osteoarthritis in an early stage, patients will also be eligible to participate in this study if they have bony swelling of at least one interphalangeal (IP) joint of the 2nd to 5th finger and/ or pain or bony swelling of at least one carpometacarpal (CMC) 1 joint
3. To have a potential for improvement (and motivation for adherence to the treatment), eligible patients have to be above or equal to an 11- point Likert scale of hand pain of at least 3 at two time points

Age group




Target number of participants


Participant exclusion criteria

1. Patients with evidence of rheumatoid arthritis or any rheumatic disease other than OA
2. Furthermore, persons with elevated C-reactive protein levels (>0.5 mg/dl) as a sign of active inflammation at the test visit and/ or with soft tissue swelling of any of the finger joints on either hand
3. Patients who have received steroid injections within the last four weeks
4. Patients who have undergone hand surgery within the last year
5. Patients who plan to receive steroid injections or hand surgery during the study period
