Muscle tone changes in the lower limbs of stroke patients induced by trunk stabilization exercises

[Purpose] The purpose of this study was to identify the effects of trunk stabilization exercises on the spasticity of the lower limbs in stroke patients. [Subject] The subject of this study was a 38-year-old male patient who experienced a spontaneous intracranial hemorrhage, and had motor paralysis symptoms and spasticity on the left side. [Methods] The Hmax/Mmax ratio was measured before and after the trunk stabilization exercises, by using proprioceptive neuromuscular facilitation techniques. [Results] The Hmax/Mmax ratio changed from 37% to 20%. [Conclusion] Trunk stabilization exercises help control the muscle tone in stroke patients.
