Abstract

Friedreich ataxia (FRDA) has a significant effect on hand function which in turn, may compromise independence and quality of life. This study sought to identify the extent of muscle weakness, spasticity and changes in joint range in the hands of individuals with FRDA. We used the Modified Tardieu Scale (MTS), testing of muscle strength and goniometry to examine hand function in 19 individuals with FRDA. Relationships between clinical measures of disease severity, functional independence and measures of hand function were also explored. We found evidence for both upper and lower motor neuron impairment in this population. Thirteen (68.0%) participants had spasticity in the dominant wrist and ..
