Based on the available evidence , motor evoked potentials at rest were the only biomarker that predicted motor outcome in individuals with severe arm impairment following stroke .
To build an underst and ing of the neurobiology underpinning arm recovery in people with severe arm impairment due to stroke , we conducted a pooled individual data systematic review to : 1 ) characterize brain biomarkers ; 2 ) determine relationship(s ) between biomarkers and motor outcome ; and 3 ) establish relationship(s ) between biomarkers and motor recovery .
Assessing Wolf Motor Function Test as Outcome Measure for Research in Patients After Stroke
Background and Purpose — The Wolf Motor Function Test ( WMFT ) is a new time-based method to evaluate upper extremity performance while providing insight into joint-specific and total limb movements . This study addresses selected psychometric attributes of the WMFT applied to a chronic stroke population . Methods — Nineteen individuals after stroke and with intact cognition and sitting balance were age- and sex-matched with 19 individuals without impairment . Subjects performed the WMFT and the upper extremity portion of the Fugl-Meyer Motor Assessment ( FMA ) on 2 occasions ( 12 to 16 days apart ) , with scoring performed independently by 2 r and om raters . Results — The  WMFT and FMA demonstrated agreement ( P < 0.0001 ) between raters at each session .  WMFT  scores for the dominant and nondominant extremities of individuals without impairment were different ( P ≤0.05 ) from the more and less affected extremities of subjects after stroke . The FMA score for the more affected extremity of subjects after stroke was different ( P ≤0.05 ) from the dominant and nondominant extremities . However , the FMA score for the less affected upper extremity of individuals after stroke was not different ( P > 0.05 ) from the dominant and nondominant extremities of individuals without impairment . The WMFT and FMA scores were related ( P < 0.02 ) for the more affected extremity in individuals after stroke . Conclusions — The interrater reliability , construct validity , and criterion validity of the WMFT , as used in these subject sample s , are supported
