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.
