Clinical assessment of hand motor performance after acquired brain injury with dynamic computerized hand dynamometry: construct, concurrent, and predictive validity.
Abstract
OBJECTIVE
To assess the construct, concurrent, and predictive validity of dynamic computerized hand dynamometry.
DESIGN
Prospective correlational study between dynamometry and functional upper limb performance.
SETTING
Hospital outpatient spasticity clinics.
PARTICIPANTS
Adults with upper motor neuron syndrome affecting the upper limb after acquired brain injury (ABI) (n=38; median age, 50 y;
range, 18-81 y) and healthy adult control participants (n=27; median age, 37 y; range, 22-62 y).
INTERVENTION
Not applicable.
MAIN OUTCOME MEASURES
Dynamic computerized dynamometry elements of hand performance (isometric force, force velocity, isometric grip work, contraction
and relaxation duration) and the Action Research Arm Test.
RESULTS
Motor elements of hand performance objectively measured by the dynamic computerized dynamometry protocol achieved moderate
to good validity when correlated with standardized measures of functional hand performance. Dynamic computerized dynamometry
identified clear differences in hand performance between participants with and without ABI. Within the ABI group, dynamic
computerized hand dynamometry achieved fair to moderate predictive validity with regards to whether a participant would be
referred for botulinum toxin A injections.
CONCLUSIONS
This study provides support for the construct, concurrent, and predictive validity of the dynamic computerized dynamometry
protocol.
