The purpose of this review was to identify the different constraints that may impact inter-limb coupling, and the rehabilitation approaches implemented to enhance those actions. Also, the measures incorporated to examine the effects of rehabilitation methods were reviewed. A literature search was conducted using CINAHL, PubMed and PsycINFO.

Results showed that the impact of sex, time after stroke, type of stroke, and age were not examined in any studies reviewed.

Regarding the dependent variables, clinician-reported and performance based scales were frequently used, while only eight studies implemented kinematic analysis, and only three examined inter-limb organization. None made explicit inferences to the existing theories of inter-limb coordination. In conclusion, important individual and task constraints on inter-limb coordination were scarcely examined.
