Abstract
Background.
Previous research has detailed the hemisphere dependence and specific
kinematic deficits observed for the less-affected arm of patients with
unilateral stroke.
Objective.
We now examine whether functional
motor deficits in the less-affected arm, measured by standardized
clinical measures of motor function, also depend on the hemisphere that
was damaged and on the severity of contralesional impairment.
Methods.
We recruited 48 left-hemisphere-damaged (LHD) participants, 62
right-hemisphere-damaged participants, and 54 age-matched control
participants. Measures of motor function included the following: (1)
Jebsen-Taylor Hand Function Test (JHFT), (2) Grooved Pegboard Test
(GPT), and (3) grip strength. We measured the extent of contralesional
arm impairment with the upper-extremity component of the Fugl-Meyer
(UEFM) assessment of motor impairment.
Results.
Ipsilesional limb
functional performance deficits (JHFT) varied with both the damaged
hemisphere and severity of contralesional arm impairment, with the most
severe deficits expressed in LHD participants with severe contralesional
impairment (UEFM). GPT and grip strength varied with severity of
contralesional impairment but not with hemisphere.
Conclusions.
Stroke survivors with the most severe paretic arm impairment, who must
rely on their ipsilesional arm for performing daily activities, have the
greatest motor deficit in the less-affected arm. We recommend
remediation of this arm(specifics please) to improve functional independence in this group
of stroke patients.
