In the trial, patients received four 1-hour sessions (once weekly), and were taught joint protection strategies. These strategies were:
- to distribute the weight of lifted objects over several joints (spread the load over two hands)
- to avoid repetitive thumb movements and putting strain on the thumb
- to avoid a prolonged grip in one position
- to use as large a grip as possible
- to reduce the effort needed to do a task (use labour-saving gadgets, avoid lifting heavy objects, and reduce the weight of what is lifted)
- to conserve energy by planning activities (organising tasks more efficiently) and pacing (taking regular short breaks).
These strategies were applied to daily tasks such as opening jars, carrying objects and filling a kettle (see Figure below and the workbook listed in Consumer resources).
Information and workbooks for patients
In addition to the joint protection strategies, patients were given standardised written information (from Arthritis Research UK) about hand OA and its management – managing pain during everyday activities, how to change habits, long-term and short-term goal setting, weekly home programs to practise skills taught, and weekly review of home programs.
They were given a workbook which contained key points from each session, photographs demonstrating how to use the joint protection principles while doing daily activities, and weekly activity diaries (see Consumer resources).
Patients were also informed about how joint protection fits into broader management of hand OA and joint pain.
