Paul Berger-Gross from Home: You are hitting the main concern I had, which is technical. Not only were they underpowered, but the group heterogeneity as seen in the SD of the functional outcome measures (relative to means) makes it nearly impossiible to obtain a significant finding. As we did, in CIMT, they might have looked at non-parametrics to address these SD's

How well-matched were the groups? What impact did the heterogeneity of participants have on findings in this study?
