Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The patient study is a phase III trial designed as a single-blinded, randomised, controlled multi-centre trial with repeated measurement events (ME). Patients will be evaluated by a blinded assessor on five occasions: twice within two weeks at baseline before intervention start (BL, T0), once after eight treatment sessions (T1), once after the intervention (T2), and once after a two month follow-up period (FU). Figure 1 illustrates the study overview.

The study focuses on the evaluation of the YouGrabber efficacy compared to conventional therapy in an outpatient setting.

Research question: Do patients after stroke in the YouGrabber training group show higher postintervention performance in the Box and Block Test (BBT) compared to patients in the conventional therapy group? Hypothesis: H0: The investigators hypothesise that there will be no group differences after 16 training sessions or after the two month follow-up period.

H1: The investigators hypothesise that there will be a group difference after the 16 training sessions and after the two month follow-up period.

Aim: The aim of the project is to design and implement a single-blinded, randomised controlled multi-centre trial comparing YouGrabber training and conventional therapy in patients after stroke.

Patients will be randomly allocated to either the experimental group (EG) or the control group (CG) after the second ME (T0). Group allocation will be based on a computer-generated randomisation list (one for each centre, (MATLAB, 2007b, Mathworks Inc., USA) created by a researcher not involved into the study. Randomisation lists and corresponding token will be stored in the clinics' pharmacy. Patients will draw a token before the first therapy session. The token will be marked and stored until study finalisation in the pharmacy.

Group allocation will remain concealed for the independent assessor until study finalisation. Patients and treating therapists will be reminded not to talk about patient's group allocation with other therapists or participants.

Patients in both study groups (EG, CG) will receive the same amount of 16 sessions lasting for 45 minutes each. During each therapy appointment patients can decide to stop the training at any time.

Patients allocated to EG will have the opportunity to participate in two semi-structured interviews to evaluate their expectations and experiences with the virtual reality therapy with YouGrabber.

Treating therapists will have the opportunity to participate in one focus group meeting to evaluate their experiences with the virtual reality training, its advantages and disadvantages. Interview and focus group participation will be voluntary.
