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. The expected decrease in the average relative power of delta and theta then increased alpha and beta. Twelve post-stroke patients and twelve healthy subjects were given 2 tasks: imaginary (motor imagery) and action (motor execution). The electrodes were placed on 8 points with 10-20 localization principle rules. Data were analyzed and tested using linear regression and paired t. The result showed that static bicycle and mirror combination therapy affects 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 ± 4.9% (p = 0.0001) and action session (motor execution) by -11.23 ± 6.1% (p = 0.0035), while average relative power of theta frequency band only decreased significantly by -6.03 ± 6.4% (p = 0.0429) an imaginary session. Then, this therapy also succeeded in enhancement relative power of alpha frequency band when given imaginary session, i.e 5.45 ± 4.2% (p = 0.0161) and action session, i.e 6.92 ± 4.6% (p = 0.0024). Furthermore, the relative power of the beta frequency band also increased when given an imaginary session by 19.23 ± 9.1% (p = 0.0026) and action session by 7.29 ± 7.5% (p = 0.0194). In conclusion, relative power, amplitude, and time (latency) of P300 and C3 to C4 ratio indicated improved health data, especially for right stroke patient subjects during therapy. © 2021 Author(s).
