Journal ArticleDOI
A Pneumatic Glove and Immersive Virtual Reality Environment for Hand Rehabilitative Training After Stroke
Lauri Connelly,Yicheng Jia,Maria L. Toro,Mary Ellen Stoykov,Robert V. Kenyon,Derek G. Kamper +5 more
TL;DR: A novel glove was developed which can provide independent extension assistance to each digit while still allowing full arm movement in stroke survivors, and can be used for training grasp-and-release movements either with real objects or with virtual objects in a virtual reality environment.
Journal ArticleDOI
Alterations in reaching after stroke and their relation to movement direction and impairment severity.
TL;DR: Stroke alters a broad array of features of reaching, yet largely the same degree of movement control is preserved across a range of target locations, and active range of motion (AROM) is a logical focus for therapy.
Journal ArticleDOI
Weakness is the primary contributor to finger impairment in chronic stroke.
Derek G. Kamper,Derek G. Kamper,Heidi C. Fischer,Erik G. Cruz,William Z. Rymer,William Z. Rymer,William Z. Rymer +6 more
TL;DR: Kamper et al. as mentioned in this paper assessed the relative contributions of several neurologic and biomechanic impairment mechanisms to overall finger and hand impairment in chronic hemiparetic stroke survivors.
Journal ArticleDOI
Impairment of voluntary control of finger motion following stroke: role of inappropriate muscle coactivation.
Derek G. Kamper,William Z. Rymer +1 more
TL;DR: It was found that voluntary MCP joint extension in hemiparetic subjects was greatly impaired in comparison with control subjects: only two of the 11 stroke subjects were able to generate even 0.21 N‐m of isometric extension torque, only two could produce positive finger extension with no load, and none could develop an isokinetic concentric extension.
Journal ArticleDOI
Relative contributions of neural mechanisms versus muscle mechanics in promoting finger extension deficits following stroke
TL;DR: It is argued that persistent and inappropriate flexor activation plays a role in limiting voluntary finger extension, and that this activation is potentially a reflection of altered supraspinal control of key spinal pathways.
