Description of intervention(s) / exposure
The study intervention is a 12-week intensive hand exercise programme using TheraPutty®.
Participants will follow a physiotherapist-prescribed 12-week programme of 4 x hand exercises, to be completed on at least 3 days of the week. The hand exercises utilise TheraPutty®, with putty resistance matched to participant's strength. At the Baseline visit, the study physiotherapist will assess participants and allocate the appropriate resistance of putty. Participants are provided with education and information on the exercise programme via a video and handout. This video and accompanying handout has been created by the Myositis Discovery Programme team, a multi-disciplinary myositis research group, for use by IBM patients under their clinical care. The video and handout is intended for use within usual clinical care where appropriate, however is not publicly available.


The exercise programme consists of 4 x core exercises and up to 7 x bonus exercises, to be completed with each hand, on at least 3 days of the week. Exercises are focussed on the hand/forearm muscle groups impacted in IBM. Participants are provided with a daily diary to record their exercise and also are emailed a weekly diary to report on compliance and provide any feedback to the study team, as well as reporting any adverse events.
Participants will gradually increase the number of repetitions of the exercises as the programme progresses. In weeks 1&2, they will complete 10 repetitions of each exercise, in weeks 3&4, this will increase to 20 repetitions. In weeks 5&6, this again increases to 30 repetitions of each exercise. At the week 6 assessment, participant's strength is re-evaluated and if progress has been made, they will be allocated to the next level strength putty, and will resume exercises with the higher resistance putty for Week 7. During weeks 7&8, they will complete 10 repetitions of each exercise, during weeks 9&10 they will completed 20 repetitions and for weeks 11&12 they will complete 30 repetitions.
