Myotonic Dystrophy type 1 (DM1) is a genetic multisystem disease causing muscle weakness and myotonia. As a result, upper limb function might become impaired. There are little research regarding rehabilitation and exercise for upper limb function in DM1. It is known from research on lower limb function in DM1 and other muscular dystrophies, that there are possibilities to improve function also in these deteriorating diseases. In this single subject experimental design study, 6-10 adults with DM1, who are at an inpatient rehabilitation center, will get intensive, but personally adapted senso- and robot assisted rehabilitation for arm- and hand function with Tyromotion Amadeo and Armeo Senso. These devices have previously been used in rehabilitation research for other neurological conditions. The participants will be followed up, and evaluated at a weekly basis, using video consultations. Fine motor skill dexterity test (9HPT) and the Nut and Bolt test will be used, and active range of motion (ROM) and muscle strenght and movement of upper limb will be measured. Furthermore, patient reported outcome measures (PROMS) on hand impairment and myotonia will be used, all with purpose to evaluate upper limb function.

Inclusion Criteria:

• Granted rehabilitation at Vikersund Rehabilitation center Genetical confirmed myotonic dystrophy diagnosis MIRS score between 2-5

Exclusion Criteria:

• MIRS score on 1 Reduced Cognitive function and unable to participate in technological rehabilitation and digital evaluation

This is a single subject experimental design study, and the data will not be available for other researchers. This is to protect the participants identity.
