Muscle spasticity is a complex and disabling motor disorder that occurs following conditions such as stroke, multiple sclerosis, spinal cord injuries, and cerebral palsy. The reliable assessment of spasticity is important for evaluating treatment effects. The Modified Modified Ashworth Scale (MMAS) is a clinical tool for measuring spasticity. This study determined whether the MMAS is reliable for the assessment of spasticity if performed by one rater across two occasions (intrarater reliability). Three muscle groups in the lower limb were assessed: hip adductors, knee extensors, and ankle plantar flexors. The reliability was moderate for the hip adductors, good for the knee extensors, and very good for the ankle plantar flexors. The overall reliability for the three muscle groups was very good. These findings indicate that the MMAS is reliable in patients with lower-limb muscle spasticity.
