One of the factors declining the function of a paretic limb of stroke patients in chronic stage is a learned nonuse phenomenon, learning the disuse of the paretic limb due to clumsiness in daily-life usage of it.Learned non-use causes ”negative” use-dependent plasticity in the brain, hence the brain area involved in motor control of the hemiplegic limb shrinks, leading to further functional decline of the hemiplegic limb, which in turn, makes recovery from paralysis more difficult. To resolve this issue, we designed a new rehabilitation system aiming to prevent the learned nonuse of the paretic limb in stroke patients by monitoring the usage of the paretic limb in daily life. As an initial step, the purpose of this study is to quantitatively evaluate the muscle activities of upper limbs in daily-life activities by using a wearable electromyograph (EMG) sensor system.
