Rather than wait for further studies write up a preliminary stroke protocol and distribute it to all 10 million yearly stroke survivors. Stroke survivors want recovery NOW, rather than years in the future OR NEVER!

OBJECTIVE:
To evaluate the effects of add-on distal upper limb robot-assisted treatment on the outcome of proximal regions.
DESIGN:
64 chronic stroke patients divided into two groups participated in the study. Group A was assigned to the proximal robot assisted rehabilitation, GroupB to the proximal and distal. Shoulder/elbow subsection of Fugl-Meyer Assessment scale was collected for Group A, whereas for Group B wrist subsection was also collected. Motricity Index was used and a set of kinematic parameters was computed for both groups.
RESULTS:
A decrease in impairment after the treatment in both groups of patients (Group A: Shoulder/elbow FM
p<0.001 and MI p<0.001;GroupB:Shoulder/elbowFM p<0.001andMI p<0.001) was found. In the GroupB wrist subsection of FM showed an improvement as well ( p<0.001). No difference between groups was found in changes of clinical scales. Movement velocity and accuracy increased after the robot-assisted treatment in both groups; group B showed a greater improvement in velocity.
CONCLUSIONS:
Robotic treatment is effective to reduce motor impairment in chronic stroke patients even if distal training added to proximal segments in the Group B does not provide any incremental benefit to the proximal segments. It remains unclear if the effectiveness of robot assisted treatment is directly related to the upper limb segment specifically treated and which order may lead to better outcome.Our study suggests that kinematic parameters should be computed in order to better clarify the role of distal training (wrist) on proximal segments (shoulder/elbow) as well.
