Stroke causes neurological disorders such as reduced muscle motor skills, as well as cognitive, visual, and coordination functions, significantly. The reduced level of independence and mobility of a person can affect their quality of life. Previous research used static bicycles or mirrors for stroke therapy. This work combined both static bicycle and mirror therapy for post-stroke patients. This study aimed to find quantitative EEG parameters that can be used to characterize neurological change. Twelve post-stroke patients and twelve healthy subjects were given 2 tasks, namely imaginary (motor imagery) and action (motor execution). The electrodes were placed on 8 points with 10-20 localization principle rules. The result showed that static bicycle and mirror combination therapy has more effect on a subject group of right stroke patients than a subject group of left stroke patients. When given imaginary session (motor imagery), in relative power of delta-band frequency of right stroke patients decreased by -18.65 ± 4,891% ( p ? 0.0001 ) and action session (motor execution) by - 11.23 ± 6,074% ( p ? 0.0035 ), while average relative power of theta frequency band only decreased significantly by -6.03 ± 6,407% ( p ? 0.0429 ) at imaginary session. Then, this therapy also succeeded in enhancement relative power of alpha frequency band when given imaginary session, i.e 5.45 ± 4,203% ( p ? 0.0161 ) and action session, i.e 6.92 ± 4,550% ( p ? 0.0024 ). Furthermore, the relative power of the beta frequency band also increased when given an imaginary session by 19.23 ± 9.104% ( p ? 0.0026 ) and action session by 7.29 ± 7.522% ( p ? 0.0194 ). In conclusion, relative power, amplitude and time of P300 and C3 to C4 ratio indicated improvement toward healthy data especially for right stroke patient subjects during therapy.
