The Adult Assisting Hand Assessment Stroke: Psychometric properties of an observation-based bimanual upper-limb performance measurement

Absolutely useless, NOTHING ON PROTOCOLS THAT WILL DELIVER RECOVERY! Assessments DO NOTHING! Interrater crapola DOES NOTHING TO GET SURVIVORS RECOVERED! Does no one in stroke know how to think? I'd have you all fired for incompetence!

The Adult Assisting Hand Assessment Stroke: Psychometric properties of an observation- 

based bimanual upper-limb performance measurement 

Objective: To investigate interrater and intrarater reliability, measurement error and 

convergent and discriminative validity of the Adult Assisting Hand Assessment Stroke (Ad- 

AHA Stroke). 

Design: Cross-sectional observational study 

Setting: Seven stroke rehabilitation centers 

Participants: A total of 118 stroke survivors (reliability sample: n=30; validity sample: n=118) 

were included (median age 67 years (interquartile range (IQR) 59-76); median time post 

stroke 81 days (IQR 57-117). 

Interventions: N/A. (With no interventions, this was absolutely fucking useless for survivors!)

Main Outcome Measures: Ad-AHA Stroke, Action Research Arm Test (ARAT), Upper 

Extremity Fugl-Meyer assessment (UE-FMA). The Ad-AHA Stroke is an observation-based 

instrument assessing the effectiveness of the spontaneous use of the affected hand when 

performing bimanual activities in adults aſter stroke. Reliability of Ad-AHA stroke was 

examined using intraclass correlation coefficients (ICC), Bland-Altman plots, and weighted 

kappa (Kw) statistics for reliability on item level. Standard error of measurement (SEM) was 

calculated based on Ad-AHA units. Convergent validity was assessed by calculating Spearman 

rank correlation coefficients between Ad-AHA stroke and ARAT and UE-FMA. Comparison of 

Ad-AHA stroke scores between subgroups of patients according to hand dominance, neglect 

and age evaluated discriminative validity. 

Results: Intrarater and interrater agreement showed an ICC of 0.99 (95% CI=0.99-0.99), a 

SEM of 2.15 and 1.64 out of 100, respectively and Kw for item scores were all above 0.79.
