OBJECTIVE: To assess the construct, concurrent and predictive validity of dynamic computerised 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 following acquired brain injury (ABI) (n=38; median age, 50 years; range 18-81) and healthy adult control participants (n=27; median age, 37; range 22-62). INTERVENTION: Nil MAIN OUTCOME MEASURES: Dynamic computerised 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 computerised dynamometry protocol achieved moderate to good validity when correlated with standardised measures of functional hand performance. Dynamic computerised dynamometry identified clear differences in hand performance between participants with and without ABI. Within the ABI group, dynamic computerised 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 computerised dynamometry protocol.
