Summary: the interventional study aims to increase the knowledge on arm and hand rehabilitation after stroke within community-based services. the primary objective of the study is to evaluate the feasibility and clinical usefulness of the arm and hand training program (focusing on functional goal- and task-oriented daily life exercises) in combination with the use of an orthotic device in terms of patient compliance and improvement of outcomes. the secondary objective is to compare the effectiveness of the program with or without the use of an orthotic device in a randomized controlled trial.

two third of all persons with stroke have a reduced arm and hand function in the acute stage. three months after the debut of stroke event, 50% of these patients will still have a remaining disability with chronic problems of hand function (kwakkel et al., 2003; lawrence et al., 2001). the consequences are grave for these individuals, considering arm and hand function to be important for independent living and related quality of life. in this context, an intervention, combining functional goal- and task- oriented exercises with a supportive orthotic device in the community-based rehabilitation unit and home environment, is hypothesized to increase perceived goal achievement, repetition, as well as the intensity of exercises. an initial feasibility study followed by a pilot randomized controlled trial could strengthen the evidence for the arm and hand interventions after stroke, and support the generalizability of the results to a larger sample. the exercise program is outlined in accordance with the frequency, intensity, type and time (fitt) principles of training. the proposed training adopts a task-oriented approach as practised today in the participating facilities. the program is standardized in close collaboration with physio- and occupational therapists on the basis of contemporary motor learning and exercise theories. an orthosis supporting the wrist will be used as supporting device, hypothetically enhancing the performance of the exercise groups. the intervention will be performed individually and will run for 12 weeks both at the community rehabilitation unit (3 times week for 3 weeks) and at home (9 weeks). time: one session at the community rehabilitation unit is approximately 60 minutes with a focus on trunk, arm and hand training. exercises at home will be carried out in minimum 2 hours per day. frequency: 5 days per week at home-exercises with/ without the orthotic device. intensity: moderate to maximal in view of strength, muscle endurance and concentration, as evaluated individually by use of borg scale. type: 1. fine motor coordination exercises such as pinch grip, writing, handling objects and stretching of fingers, hand, and wrist; 2. various combined activities such as turning pages, distributing cards, washing up, folding laundry, sweeping floor; 3. strengthening exercises such as gross motor exercises for trunk, arm, hand and fingers with and without weights.
