Abstract: The purpose of this study was to investigate whether the early developmental patterns
of skilled reaching identified in a previous study occur after stroke in adults. The temporal
phases of the gestures performed during skilled reaching were compared between twelve stroke
subjects, their matched controls, and the developmental patterns during early infancy. Results
show that developmental patterns occur after stroke with respect to skilled reaching. Implications
for the organization of reaching and recovery after stroke are discussed.

Abstract: Abnormal torque coupling between shoulder abduction and elbow flexion in
hemiparetic stroke has been well documented and elbow flexion has been shown to become more
pronounced with increasing levels of shoulder abduction torque or limb support. However, no
studies have investigated how this effect is manifested at the fingers and wrist. Therefore, the
first part of this study investigated whether isometric finger flexion (FF) forces would increase as
a function of active limb support.
Using the Arm Coordination Training 3-D (ACT-3D) device, which can alter shoulder abduction
torques by generating forces along its vertical axis, the paretic arm of 7 individuals with
hemiparetic stroke and the non-paretic arm of 4 controls were progressively loaded through 11
