The overall goal is to investigate the effectiveness of a novel intervention - Breathing-controlled electrical stimulation (BreEStim) on finger flexor spasticity reduction and hand function improvement in chronic stroke with moderate impairment.

RECRUITINGChange in finger flexor spasticity measured by Modified Ashworth Scale (MAS)
MAS will be performed to check changes of finger flexor spasticity after one session of treatment. The Modified Ashworth scale (MAS) scoring is categorical and ranges from 0 to 4, as follows: 0: No increase in muscle tone 1. Slight increase in muscle tone, manifested by a catch and release or by minimal resistance at the end of the range of motion when the affected part(s) is moved in flexion or extension 1+: Slight increase in muscle tone, manifested by a catch, followed by minimal resistance throughout the remainder (less than half) of the range of motion (ROM) 2. More marked increase in muscle tone through most of the ROM, but affected part(s) easily moved 3. Considerable increase in muscle tone, passive movement difficult 4. Affected part(s) rigid in flexion or extension
Time frame: Baseline, 5 minutes after intervention
Change in finger extensors and hand function measured by Fugl Myer Assessment (FMA) Scale
FMA will be assessed to test function changes of finger extensors and hand function after one session of treatment. The upper limb motor function domain of the FMA scale will be used, and the score range for this domain is 0 to 66, with a higher score indicating better function.
Time frame: Baseline, 5 minutes after intervention
