Computer Therapy Compared With Usual Care for People With Long-Standing Aphasia Poststroke

TLDR

The study aimed to assess the feasibility of a randomized controlled trial evaluating self‑managed computer therapy for long‑standing aphasia after stroke. Thirty‑four participants were randomized (17 per group) to a 5‑month self‑managed computer treatment with volunteer support or usual care, followed by 3 months of no intervention, and the intervention included roughly 4 h 43 min of therapy and volunteer time, yielding about 25 h of independent practice. At 5 months the computer‑therapy group improved naming ability by.

Abstract

The purpose of this study was to test the feasibility of conducting a randomized controlled trial to study the effectiveness of self-managed computer treatment for people with long-standing aphasia after stroke.In this pilot single-blinded, parallel-group, randomized controlled trial participants with aphasia were allocated to self-managed computer treatment with volunteer support or usual care (everyday language activity). The 5-month intervention period was followed by 3 months without intervention to investigate treatment maintenance.Thirty-four participants were recruited. Seventeen participants were allocated to each group. Thirteen participants from the usual care group and 15 from the computer treatment group were followed up at 5 months. An average of 4 hours 43 minutes speech and language therapy time and 4 hours volunteer support time enabled an average of 25 hours of independent practice. The difference in percentage change in naming ability from baseline at 5 months between groups was 19.8% (95% CI, 4.4-35.2; P=0.014) in favor of the treatment group. Participants with more severe aphasia showed little benefit. Results demonstrate early indications of cost-effectiveness of self-managed computer therapy.This pilot trial indicates that self-managed computer therapy for aphasia is feasible and that it will be practical to recruit sufficient participants to conduct an appropriately powered clinical trial to investigate the effectiveness of self-managed computer therapy for people with long-standing aphasia.
