Scientific titleSelf management, joint protection education and exercises in hand osteoarthritis: a randomised controlled trial in the community
Study acronymSMOotH
Study hypothesisPrimary questions:
1. Is joint protection delivered by an Occupational Therapist (OT) more effective in reducing hand pain and disability than no joint protection in people with hand osteoarthritis (OA) in primary care?
2. Are hand exercises delivered by an OT more effective in reducing hand pain and disability than no hand exercises in people with hand OA in primary care?

Secondary question:
If joint protection and hand exercises are combined, is this more effective in reducing hand pain and disability than usual care in people with hand OA in primary care?
Ethics approval(s)Ethics approval pending from the Central Manchester Research Ethics Committee (REC) as of 26/11/2007 (ref: 07/H1008/235). A favourable opinion was given by Central Manchester REC for our study on 22/02/2008.
ConditionHand osteoarthritis
InterventionGroup 1 - usual care:
Group 1 will receive information on general practice (GP) headed notepaper to continue with their own self-management approaches, which they will be asked to record in a diary, will receive standard advice on the use of analgesia and will be given the Arthritis Research Campaign (ARC) leaflet 'Looking after your joints'.

Group 2 - usual care and joint protection principles:
Participants will receive the same information and instructions as Group 1 above. In addition they will receive four group intervention classes held in a local OT department. The OT interventions will be held once a week for a maximum of 60 minutes and will involve 6 - 8 participants. Participants will be taught joint protection principles.

Group 3 - usual care and hand exercises:
Participants will receive the same information and instructions as Group 1 above. In addition they will receive four group intervention classes held in a local OT department. The OT interventions will be held once a week for a maximum of 60 minutes and will involve 6 - 8 participants. Participants will be taught hand exercises.

Group 4 - usual care and joint protection principles and hand exercises:
Participants will receive the same information and instructions as Group 1 above. In addition they will receive four group intervention classes held in a local OT department. The OT interventions will be held once a week for a maximum of 90 minutes and will involve 6 - 8 participants. Participants will be taught both joint protection principles and hand exercises.

The OT group interventions (groups 2 - 4) will include a general introduction, education on hand OA and its management and management of pain during everyday activities. Educational-behavioural approaches will be adopted with goal-setting, pacing, problem-solving and challenging unhelpful beliefs. Participants will be encouraged to practice techniques taught in the classes, which will be reinforced by a participant manual. The joint protection approaches and hand exercises will be based on those previously used in rheumatoid arthritis with adaptation for hand OA.

Outcomes for Groups 2 - 4 will be compared with outcomes for Group 1.
Intervention typeOther
Primary outcome measureThe primary outcome will combine the pain and function subscales of the Australian/Canadian hand osteoarthritis measure (AUSCAN) with a global assessment of improvement (6 point scale: completely better, much better, better, same, worse, much worse) according to the Osteoarthritis Research Society International (OARSI)/Outcome Measures in Rheumatology (OMERACT) criteria to determine whether each individual is a 'responder' to treatment.

Outcome measures will be completed at baseline, 3, 6 and 12 months. The primary end point will be 6 months.
Secondary outcome measures1. Global assessment of change of hand problem at 3, 6 and 12 months
2. Individual subscales of the AUSCAN (Pain, stiffness and function) at recruitment, baseline, 3, 6 and 12 months
3. Hand pain manikin at recruitment, 3, 6 and 12 months. Participants are asked if they have had any ache or pain that has lasted for one day or longer in their hands. Individuals responding positively to this question are then asked to shade in a diagram of the hands (backs and palms) indicating where this ache or pain has been experienced.
4. Average pain severity over the past 3 days, assessed at baseline, 6-month clinic assessment and at 12 months
5. Severity rating of participant nominated main functional problem over the past 3 days, assessed at baseline and 6-month clinic assessment, 3 and 12 months
6. Frustration related to hand disability, assessed at baseline, 3, 6 and 12 months
7. Participation restriction, assessed at recruitment, 3, 6 and 12 months
8. Quality of life:
8.1. EuroQol EQ-5D instrument at baseline, 3, 6 and 12 months
8.2. 12-item short form version 2 (SF-12v2) questionnaire at recruitment, 3, 6 and 12 months
9. Generic measure of disability, assessed by SF-12v2 at recruitment, 3, 6 and 12 months
10. Self-efficacy in relation to pain (Arthritis Self-Efficacy pain subscale), assessed at baseline, 3, 6 and 12 months
11. Illness perceptions, measured by Illness Perceptions Questionnaire Revised (IPQ-R) modified for hand OA, assessed at recruitment, baseline, 3, 6 and 12 months
12. Side-effects of treatment and adverse events
13. Co-interventions:
13.1. From consultation download: follow-up visits to the GP, prescription of medication including non-steroidal anti-inflammatory drugs (NSAIDs), referral for other treatment such as surgery
13.2. From self-reported questionnaires: self-help remedies, contacts with private health care, over the counter medicines, use of hand splints
14. Satisfaction with care, assessed at 3 and 6 months
15. Self-reported behaviour change, assessed at baseline, 3, 6 and 12 months
