Dynamic computerised hand dynamometry: measuring outcomes following upper limb botulinum
toxin-A injections in adults with acquired brain injury
Sammanfattning
OBJECTIVES: Evaluate upper limb performance in adults receiving botulinum toxin-A injections
for upper limb spasticity using Dynamic Computerised Hand Dynamometry and current clinical
measures.
DESIGN: Pre-test/post-test clinical intervention study.
Subjects/Patients: Twenty-eight participants with spasticity following acquired brain injury.
METHODS: Botulinum toxin-A effects were measured 4 weeks post-injection using Dynamic
Computerised Dynamometry. Current clinical upper limb performance measures spanning the
International Classification of Functioning, Disability and Health domains were also conducted at the
Body Function and Structure (Modified Ashworth Scale; Tardieu Scale) and Activity (Action Research
Arm Test; Goal Attainment Scaling; patient disability and carer burden scales) domains. Dynamic
Computerised Dynamometry hand performance measures were correlated with performance on
current clinical measures.
RESULTS: Significant post botulinum toxin-A changes were identified on current clinical measures
and the Dynamic Computerised Dynamometry. Dynamic Computerised Dynamometry results
correlated with current clinical measures demonstrating functional upper limb change across the
Body Function and Structure and Activity domains.
CONCLUSION: Dynamic Computerised Dynamometry sensitively assesses the effects of botulinum
toxin-A on upper limb spasticity during a simple, functionally based, grasp and release task. Unlike
current measures, the Dynamic Computerised Dynamometry provides information across the Body
Function and Structure and Activity domains of the International Classification of Function.
