Development of the Chedoke Arm and Hand Activity Inventory: theoretical constructs, item generation, and selection.

The Chedoke Arm and Hand Activity Inventory (CAHAI) was developed to address the need for a valid, clinically relevant, responsive functional assessment of the recovering paretic upper limb. The purpose of this article is to describe the development of the measure including its theoretical constructs, item generation, and item selection. From the literature, survivors of stroke, and their caregivers, 751 items were generated. Using factor analyses stem leaf plots, clinical judgment, and pilot testing on individuals with stroke, the list was reduced to 13 bilateral, real-life items. Research continues to provide evidence of the CAHAI's test-retest and interrater reliability as well as construct, concurrent, and longitudinal validity.

Progressive resistance strengthening exercises after stroke: a single-blind randomized controlled trial.

OBJECTIVE: To determine the effectiveness of progressive resistance strengthening exercises to improve gross motor function and walking in patients receiving intensive rehabilitation after stroke. DESIGN: Randomized controlled trial. SETTING: Five inpatient rehabilitation programs affiliated with teaching hospitals. PARTICIPANTS: Inclusion criteria included less than 6 months poststroke and recovery of the leg stages 3 to 5 on the Chedoke-McMaster Stroke Assessment (CMSA). INTERVENTIONS: Both groups received conventional physical therapy programs. In addition, the experimental group performed 9 lower-extremity progressive resistance exercises 3 times a week for the duration of their stay, whereas the control group did the same exercises and for the same duration but without resistance. MAIN OUTCOME MEASURES: The Disability Inventory of the CMSA and the 2-minute walk test (2MWT) at baseline, 4 weeks, discharge, and 6 months after discharge. RESULTS: Over the length of stay, the rate of change in the Disability Inventory was.27 points per day in the experimental group and.29 points per day in the control group; the between-group difference was -.02 points per day (95% confidence interval [CI], -.10 to.06; P=.62). At discharge, the rate of change in the 2MWT was -.01 m in the experimental group and.15m in the control group; the between-group difference was -.16 m (95% CI, -.37 to.05; P=.14). CONCLUSIONS: Progressive resistance strengthening exercises as applied in our study were not effective when compared with the same exercises given without resistance.
