Paresis, Stroke
Conditions
Brief summary
The primary study objective is to compare post-stroke upper extremity (UE) movement while wearing a brace called the MyoPro 2 Motion G versus UE movement while wearing a resting splint and no device in stroke survivors with moderate UE dysfunction. During the study, subjects will undergo general training in the operation of the EMG-controlled orthosis and the comparison orthosis, and then guided through a series of standard clinical outcome measures. These outcome measures will allow the researchers to directly compare the relative benefit of the MyoPro 2 Motion G with a resting hand splint and no device in reducing UE impairment and increasing UE dexterity and functional task performance.
Interventions
DEVICEMyoelectric UE Device-UE Orthosis-No Device
all subjects receive 2 education sessions, during which they are trained on the donning and use of the MyoPro 2 Motion-G, orthosis, and no device, all on the affected UE. The presentation and training on these interventions is non-randomized and administered to all subjects.

Inclusion criteria
* Manual Muscle Test \>1/5 in the paretic biceps, triceps, finger extensors and finger flexors; * score \> 10 \< 30 on the Upper extremity Fugl Meyer AND active shoulder flexion of at least 30 degrees with device weight on affected arm; * Ability to generate consistent, detectable EMG signal from the bicep/tricep upper arm and distal forearm flexor and extensor sensor sites with wrist in neutral, and fingers in neutral. At rest, achieve an EMG of 5 or below on myConfig (wrist and fingers in neutral and elbow extended); with gain at \< 10 and boost \<12, able to reach a threshold of 10 at both bicep and wrist flexors/extensors; * a single stroke that is the cause of arm impairment, experienced \>12 months ago; if there are additional asymptomatic lesions (as diagnosed by MRI), these subjects may also be included. Those with another symptomatic stroke in addition to the stroke causing arm impairment are excluded; * score \>70 on the Modified Mini Mental Status Examination; * age \>18\< 85; * \> 6 months since previous functional or therapeutic use of an upper extremity myoelectric orthosis; * Height \>5'0; * Weight \>110\< 250 lbs.; * Forearm circumference (at widest part) \<13 in.; * Bicep circumference \>9 \<15 in.; * Upper arm length \>5.5 in.; * Wrist thickness (anterior- posterior) \<1.75 in.; * ability to stand with minimal assistance
Exclusion criteria
* \> 5 on a 0-10 Numeric Pain Rating Scale for pain in the paretic hand, arm or shoulder; * \> 3 on the Modified Ashworth Spasticity Scale in the paretic elbow, \>2 at wrist or fingers; * \< 2.5 on the Alexander Apraxia scale; ' * history of neurological disorder other than stroke; * change in anti-spasticity medications in the last 6 months, and/or receipt of botulinum toxin in the paretic UE in the previous 4 months; * elbow contracture greater than 10 degrees; * inability to passively extend fingers while wrist is in neutral; * other conditions or physical/mental attributes that may undermine safety and/or full participation in the study; * bilateral hemiparesis.
