Abstract:
Objective:To seek any correlation between hypoesthesia and sensory disturbance to motor function among stroke survivors.Methods:One hundred and two stroke survivors with hyperalgesia were treated with sinusoidal alternating current at 2000Hz, 250Hz or 5Hz to stimulate the fingers and toes on their healthy and hemiplegic sides. Current perception thresholds (CPTs) and pain tolerance thresholds (PTTs) were recorded. The correlation between the degree of sensory disturbance in the hemiplegic limb and muscle strength was explored.Results:①The degree of sensory impairment in those who had suffered a cerebral hemorrhage was significantly greater than among those with cerebral infarction, without significant difference in pain tolerance between different genders and affected sides. ②All of the patients with sensory impairment showed significantly higher CPT and PTT values at the different frequencies, with a positive correlation between them. ③The CPT values of the affected hand and foot at the different frequencies were negatively correlated with muscle strength on the affected side.Conclusions:Both CPT and PTT can usefully represent the degree of sensory disturbance after a stroke. The CPT values of patients with different types of stroke are significantly different, and the degree of sensory disturbance is correlated with the muscle strength of the affected side. Therefore, it is helpful for prognostic judgment and individualized rehabilitation treatment planning by quantifying the degree of sensory disturbance.
