Abstract

Objective: To demonstrate the feasibility and efficacy of a new video-observation training method (intensive visual simulation) to improve upper limb function.

Design: Small sample, randomized, evaluator-blind, monocentric study.

Patients: Seventeen early subacute ischaemic stroke patients with complete hemiplegia were randomly assigned to the therapeutic group (n = 8) or control group (CG, n = 9).

Methods: Thirty sessions of intensive visual simulation combined with corrected visual feedback (therapeutic group) or uncorrected visual feedback (control group) were performed over 6 weeks on top of a standard rehabilitation programme.

Main Outcome Measure: 400-point hand assessment test (400p-HA).

Secondary Outcome Measures: Box and Blocks (B&B), Purdue Pegboard test, Minnesota.

Results: The 400p-HA test improved significantly from T0 to 6 months for both groups, with a significant difference between groups at 3 months (MW-UT p = 0.046) and 4 months (MW-UT p = 0.046) in favour of the therapeutic group. One-phase exponential modelling of 400p-HA showed a greater plateau for the therapeutic group (F test p = 0.0021). There was also faster recovery of the ability to perform the B&B tests for the therapeutic group (log-rank test p = 0.03).

Conclusion: This study demonstrated the feasibility and potential efficacy of an intensive visual simulation training programme to improve upper limb function in subacute stroke patients. A larger study is needed to confirm these results.
