The effect of physiotherapeutic ultrasound on muscle spasticity in patients with hemiplegia: a pilot study.

BACKGROUND

Spasticity is one part of the upper motor neuron syndrome. Untreated spasticity not only causes loss of motor control that results in functional disability, but can easily lead to joint contractures as well. Physical therapy plays an important role in the management of patients with spasticity. Among the modalities, Therapeutic ultrasound has become an important modality for treatment of various conditions including spasticity.

OBJECTIVES

The aim of this study is to determine the effect of ultrasound on spasticity.

METHODS

In this before-after study, four adult patients (mean age: 57.5 +/- 14.43) with first ever stroke and resulting in hemiplegia participated in the study. The outcome measures were the Ashworth Scale for the assessment of spasticity, ankle passive and active range of motion, and the Hmax: Mmax ratio.

RESULTS

The mean of Ashworth scores, Hmax:Mmax ratio, and passive range of motion in ankle joint improved after treatment with ultrasound, but it was not statistically significant (p > 0.05).

CONCLUSIONS

The study did not show a significant decrease in spasticity after ultrasound therapy. A study with a large number of patients and a control group would clarify the effects of ultrasound on spasticity.
