The purpose of the study is to investigate if occupational therapy may delay or prevent the need for surgery in patients with carpometacarpal(CMC) osteoarthritis (OA) who are scheduled for surgery in the CMC-joint.

Our study hypothesis is that compared to participants in the intervention group, significantly more participants in the control group have received CMC-surgery after two years.

Other: Occupational therapy
Occupational therapy in the waiting period before surgery. Occupational therapy comprises orthoses for the CMC-joint, hand exercises, and use of alternative working methods and assistive devices. The participants are encouraged to perform hand exercises three times a week for the first 12 weeks, and to use orthosis as much as possible, both during daytime (day orthosis) and night time (night orthosis).

Detailed Description:

Hand osteoarthritis (OA) is one of the most prevalent musculoskeletal diseases in an adult population, and approximately 68% of people between the ages of 71 and 80 years have radiographic OA in the carpometacarpal (CMC) joint.

Currently, there is no cure for hand OA. However, several studies have demonstrated that hand exercises and CMC-orthoses may reduce pain and improve grip strength, and in a recent study, assistive devices improved activity performance and satisfaction with performance in people with hand-OA. Still, most people do not receive any such treatment, but those with severe CMC-OA are often referred for surgery in this joint. The effect of occupational therapy to prevent or delay need for surgery CMC-OA has been investigated in a small study with 33 participants, but randomised controlled trails (RCT) of good quality are needed.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients with CMC-OA who are referred for review for the need for surgery in the CMC joint.

Exclusion Criteria:
