Composite active range of motion (CX_A) and relationship with active function in upper and lower limb spastic paresis.

The pattern of changes in CX A , which showed an overall trend toward greater improvements with repeated treatment cycles followed by a plateau at later cycles, reflects the results observed for other outcome measures of the original studies. 10 – 12 Historically, composite outcome measures used in rehabilitation studies have tended to be generated from passive resistance measures, for example, by summing modified Ashworth Scale scores of multiple joints to assess muscle tone changes in the affected limb. 18 – 30 Although helpful, these approaches have overlooked assessment of active motion or active function.
