Elbow Extension Predicts Motor Impairment and Performance after Stroke
نویسندگان
چکیده
Background and Purpose. Kinematic motion analysis has helped to characterize poststroke reaching strategies with the hemiparetic arm. However, the relationships between reaching strategy and performance on common functional outcome measures remain unclear. Methods. Thirty-five participants were tested for motor performance and motor impairment using the Wolf Motor Function Test (time and functional ability measure) and Fugl-Meyer assessment, respectively. Kinematic motion analysis of a forward reaching paradigm provided potential predictors of reaching strategy including shoulder flexion, elbow extension, and trunk displacement. A stepwise linear regression model with three potential predictors was used in addition to Pearson-product moment correlations. Results. Kinematic analysis of elbow extension predicted performance on both the Wolf Motor Function Test and Fugl-Meyer assessment. Shoulder flexion and trunk displacement did not significantly predict functional or reaching time outcomes. The Wolf Motor Function Test and the Fugl-Meyer assessment were highly correlated. Conclusions. The ability to incorporate elbow extension during reach is a significant predictor of motor performance and hemiparetic arm motor capacity after stroke.

Repetitive bilateral arm training with rhythmic auditory cueing improves motor function in chronic hemiparetic stroke.
BACKGROUND AND PURPOSE Chronic upper extremity hemiparesis is a leading cause of functional disability after stroke. We investigated the hypothesis that bilateral arm training with rhythmic auditory cueing (BATRAC) will improve motor function in the hemiparetic arm of stroke patients. METHODS In this single group pilot study we determined the effects of 6 weeks of BATRAC on 14 patients with c...
متن کاملTask-specific training with trunk restraint on arm recovery in stroke: randomized control trial.
BACKGROUND AND PURPOSE Task-specific training improves functional outcomes after stroke. However, gains may be accompanied by increases in movements compensating for motor impairments. We hypothesized that restriction of compensatory trunk movements may encourage recovery of premorbid movement patterns leading to better functional outcomes. The goal was to determine whether task-specific traini...

متن کاملImpact of Extension Splint on Upper Extremity Motor Components and Function in Chronic Stroke Patients
Objectives: Spasticity and contracture in flexor muscles of the wrist may occur after stroke, especially in which early recovery did not appear. Splints are prescribed to reduce spasticity and to prevent contracture after stroke. Although there is a few research in this field. The aim of this study was to examine the impact of the Extension splint on function, spasticity, and range of motion of...
متن کاملValidity of movement pattern kinematics as measures of arm motor impairment poststroke.
BACKGROUND AND PURPOSE Upper limb motor impairment poststroke is commonly evaluated using clinical outcome measures such as the Fugl-Meyer Assessment. However, most clinical measures provide little information about motor patterns and compensations (eg, trunk displacement) used for task performance. Such information is obtained using movement quality kinematic variables (joint ranges, trunk dis...
