The cortical control of cycling exercise in stroke patients: An fNIRS study

摘要: Stroke survivors suffering from deficits in motor control typically have limited functional abilities, which could result poor quality of life. Cycling exercise is a common training paradigm for restoring locomo- tion rhythm patients. The provision speed feedback has been used to facilitate the learning controlled cycling performance and neuromuscular affected leg. However, central mechanism relearning active passive pedaling motions stroke patients not investigated as exten- sively. aim this study was measure cortical activation patterns during with with- out power-assisted (passive) A frequency-domain near- infrared spectroscopy (FD-NIRS) system detect hemodynamic changes resulting neuronal activity bilateral sensorimotor cortices (SMCs), supplementary areas (SMAs), premotor (PMCs). variation level symmetry mus- cle rectus femoris were evaluate performance. results showed that had similar pattern observed without but smaller intensity SMC unaffected hemisphere.
