All

Inclusion criteria

Inclusion criteria: Inclusion criteria were defined as patients with upper limb motor impairment after stroke and a Modified Ashworth Scale (MAS) score of 1 or higher in the flexor carpi radialis muscle.

Exclusion criteria

Exclusion criteria: Exclusion criteria were as follows: participants with a FCR MAS score of 4, those unable to maintain the starting position of the examination due to joint range of motion limitations, those with upper limb motor disorders not caused by stroke, those with bilateral hemiplegia, those with a Hasegawa Dementia Scale Revised (HDS-R) score of 21 or lower, and those with superficial or deep sensory loss.

Design outcomes

Primary

MeasureTime frame
In this study, H-reflexes will be measured from the paretic-side flexor carpi radialis muscle before and during vibratory stimulation. The waveform analysis parameters of the H-reflex will include the average H-wave amplitude and the H/M amplitude ratio.

Secondary

MeasureTime frame
In this study, muscle hardness will be measured in addition to the H-reflex.
