Motor recovery of the ipsilesional upper limb in subacute stroke

I don't understand. Ipsilesional : the symptoms occur on the same side of the body as the lesion.Are they trying to say the good side has recovery problems? I don't remember doing any rehab on the 'good' arm. Amy?

Abstract: Study investigated the time-related changes in motor performance of the ipsilesional upper limb in subacute poststroke patients by using clinical and kinematic assessments. Nineteen stroke patients were included in the study less than 30 days after a first unilateral ischemic/hemorrhagic stroke. The control group was composed of age-matched, healthy volunteers. Clinical and kinematic assessments were conducted once a week during 6 weeks and 3 months after inclusion. Clinical measures consisted of the Fugl-Meyer Assessment, the Box and Block Test (BBT), the Nine-Hole Peg Test (9HPT), and the Barthel Index. A 3-dimensional motion recording system was used during a reach-to-grasp task to analyze movement smoothness, movement time, and peak velocity of the hand. Healthy controls performed both clinical (BBT and 9HPT) and kinematic evaluations within a single session. Results indicated that recovery of ipsilesional upper arm capacities increased over time and leveled off after a 6-week period of rehabilitation, corresponding to 9 weeks poststroke. At study discharge, patients demonstrated similar ipsilesional clinical scores to controls but exhibited less smooth reaching movements. No effect was found of the hemispheric side of the lesion on ipsilesional motor deficits. The findings provide evidence that ipsilesional motor capacities remain impaired at least 3 months after stroke, even if clinical tests fail to detect the impairment.
