The most important predictive factors for upper limb recovery following stroke appears to the initial severity of motor impairment or function
Objective : To systematic ally review and summarize the current available literature on prognostic variables relating to upper limb recovery following stroke .
To identify which , if any variables predict upper limb recovery following stroke .
Change of strength and rate of rise of tension relate to functional arm recovery after stroke.
OBJECTIVE To examine the relationship between individual strength parameters and functional motor ability over time during rehabilitation in stroke patients . DESIGN A multiple-baseline experiment with assessment at inclusion and after 3 and 6 weeks . SETTING Secondary -care rehabilitation center . PARTICIPANTS A convenience sample of 16 subacute stroke patients . INTERVENTIONS Not applicable . MAIN OUTCOME MEASURES Maximal voluntary force and rate of rise of tension of h and grip , wrist extension , and elbow flexion and extension were recorded at all 3 times . At the same time , functional motor assessment s were evaluated by the  Action Research Arm Test ( ARAT ) , Box and Block test , and Rivermead Test . RESULTS We found no correlation between maximal voluntary force increases of various muscle contractions measurements . Neither the increase of grip strength nor that of wrist extension force correlated with improvement in ARAT score . Yet the improvement in the rate of rise of tension of h and grip ( Spearman rho=.91 ) and of wrist extension ( Spearman rho=.73 ) correlated with the improvement of the ARAT score and explained 77 % of the variance of the ARAT . CONCLUSIONS The change in the rate of rise of tension of the h and grip has a better predictive value for the functional recovery compared to the change in maximal voluntary force in patients with moderate arm and h and weakness after stroke . The rate of rise of tension of h and grip seems an adequate quantifiable parameter to detect small improvements during functional recovery
