Background
Recent studies have attempted to disaggregate therapeutic intervention packages by looking at the impact of structure and process
characteristics of environment upon outcome. However, what is commonly referred to as the ’black box’ of therapy has yet to be
comprehensively unpacked. This failure to analyse the components of therapy means that it remains unclear how much therapy should
be provided, who should provide it, and which patients should be targeted to ensure that functional outcomes are maximized. This
review, therefore, seeks to assess the effectiveness of specific therapeutic interventions in the rehabilitation of the paretic upper limb
post stroke.
