'Measurements' DO NOTHING FOR RECOVERY! I'd fire all of you for not understanding the goal of stroke research! RECOVERY, RECOVERY, RECOVERY! Nothing else!

Validity, responsiveness, and clinically important difference of the ABILHAND questionnaire in patients with stroke.
Objective
To investigate the criterion-related validity, responsiveness, and clinically important differences of the ABILHAND questionnaire in patients with stroke.
Design
Validation and clinimetric study.
Setting
Participants
Patients with stroke (N=51). A total of 51 patients with stroke received 1 of 3 upper extremity rehabilitation programs for 4 weeks.
Main Outcome Measures
The ABILHAND and the criterion measures, including the Stroke Impact Scale (SIS), FIM, Nottingham Extended Activities of Daily Living (NEADL), and accelerometers, were administered at pretreatment and posttreatment. The score of the ABILHAND, given in logits, was based on the conversion of the ordinal score into a linear measure of ability.
Results
Correlation coefficients (Pearson r) were moderate to large between the ABILHAND and SIS physical domains (.54–.66), fair to moderate between the ABILHAND and FIM-motor and NEADL (.28–.48), and moderate between the ABILHAND and accelerometer data (.45–.54). The responsiveness of the ABILHAND was large (standardized response mean=1.27). The minimal clinically important difference range for the ABILHAND was .26 to .35, and 51.0% of the patients showed a positive change that exceeded the lower bound of a clinically important difference after intervention.
Conclusions
The results support that the ABILHAND is an appropriate outcome measure for assessing upper extremity performance in daily activities in patients with stroke and is sensitive to detect change after rehabilitative interventions. The change score of a patient with stroke on the ABILHAND should reach .26 to .35 logits points to be regarded as a clinically important change.
