Do patients with congenital hemiparesis and ipsilateral corticospinal projections respond differently to constraint-induced movement therapy?
This study investigates whether the type of corticospinal reorganization (identified by transcranial magnetic stimulation) influences the efficacy of constraint-induced movement therapy (CIMT). Nine patients (five males, four females; mean age 16y [SD 6y 5mo], range 11-30y) controlling their paretic hand via ipsilateral corticospinal projections from the contralesional hemisphere and seven patients (three males, four females; mean age 17y [SD 7y], range 10-30y) with preserved crossed corticospinal projections from the affected hemisphere to the paretic hand underwent 12 consecutive days of CIMT. A Wolf motor function test applied before and after CIMT revealed a significant improvement in the quality of upper extremity movements in both groups. Only in patients with preserved crossed projections, however, was this amelioration accompanied by a significant gain in speed, whereas patients with ipsilateral projections tended to show speed reduction. These data, although preliminary, suggest that patients with congenital hemiparesis and ipsilateral corticospinal projections respond differently to CIMT.
