Introduction: Stroke causes upper motor neuron syndrome, and spasticity of foot ankle complex further leads to equine gait and posture stability disturbance. Botulinum type A (BTX-A) injection has been widely used in treating spasticity, yet few studies report its effect on posture control. This study aimed at applying BTX-A injection in treating ankle-foot complex spasticity and investigating its effect on ankle strategy use with sensory organization test.
Material and method: 9 stroke patients and 5 healthy subjects were recruited. BTX-A injection was applied over calf flexor muscle group under electrical stimulation guide. Strategy score (ST) and Composite score were assessed using standard sensory organization test(SOT) with SMART Balance Master. The higher ST and Composite score indicated that the subjects used more ankle strategy.
The individual test conditions were as following: EO: eyes open; EC: eyes closed; SV: swayed vision and fixed support; EOSS: eyes open and swayed support; ECSS: eyes closed and swayed support; SVSS: swayed vision and swayed support). For the patient group, SOT was performed before BTX-A injection, and at 4 weeks, 8 weeks and 12 weeks follow up. For control group, the assessments were performed once. Generalized estimating equation was implemented for data analysis, and set p<0.05 as statistical significance.
