OBJECTIVES: To examine the validity of a newly developed tissue compliance device to measure muscle tone and to quantify the level of severity of the @entity508 . DESIGN: Validity study. SETTING: Research laboratory. @entity1 : Twenty subjects, 10 with @entity74 ( @entity306 or adult-onset @entity64 ) who comprised the experimental group; and 10 nondisabled, age-equivalent subjects, who served as controls. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Muscle tone of the biceps brachii muscle was assessed with the Myotonometer and @entity2653 ( @entity2653 ). The Myotonometer was used to quantify the muscle's resistance to stretch in a relaxed state and during maximal voluntary isometric contractions. Analyses of variance determined differences among subjects. Correlations between Myotonometer measurements and @entity2653 scores were calculated. RESULTS: Significant differences (p < .05) were observed between experimental and control groups and between the involved and uninvolved extremities of the experimental group with Myotonometer measurements. Correlations between @entity2653 scores and Myotonometer measurements ranged from .64 to .81. CONCLUSION: The Myotonometer effectively identified differences in the @entity508 of the biceps brachii muscle in subjects with UMN involvement. Correlations with the @entity2653 were moderate to high.

Assessing the XXXX of individuals with upper motoneuron involvement: validity of the myotonometer.
