Intra- and interrater reliabilities of the Myotonometer when assessing the spastic condition of children with cerebral palsy.

The purposes of this study were to assess intra- and interrater reliabilities by novice users of the Myotonometer (Neurogenic Technologies, Inc., Missoula, MT), a portable electronic device that quantifies muscle tone (stiffness) and paresis, in assessing children with cerebral palsy. Two raters used the Myotonometer to assess the biceps brachii and medial gastrocnemius muscles of 10 children with spastic-type cerebral palsy.
