Abstract
Most post-stroke patients experience varying degrees of impairment in upper limb function and fine motor skills. Occupational therapy (OT) with other rehabilitation trainings is beneficial in improving the strength and dexterity of the impaired upper limb. An accurate upper limb assessment should be conducted before prescribing upper limb OT programs. In this paper, we present a novel multisensor method for the assessment of upper limb movements that uses kinematics and physiological sensors to capture the movement of the limbs and the surface electromyogram (sEMG). These sensors are Kinect, inertial measurement unit (IMU), Xsens, and sEMG. The key assessment features of the proposed model are as follows: (1) classification of OT exercises into four classes, (2) evaluation of the quality and completion of the OT exercises, and (3) evaluation of the relationship between upper limb mobility and muscle strength in patients. According to experimental results, the overall accuracy for OT-based motion classification is 82.2%. In addition, the fusing of Kinect and Xsens data reveals that muscle strength is highly correlated with the data with a correlation coefficient (CC) of 0.88. As a result of this research, occupational therapy specialists will be able to provide early support discharge, which could alleviate the problem of the great stress that the healthcare system is experiencing today.

Their surface electromyogram (sEMG) were used to determine the reliability of the modified TextCNN model, whereas their motion data were used to determine the completion and quality of the actions during Occupational therapy (OT) sessions as part of the post-stroke patient assessment

Summary
Cerebrovascular accident known as stroke has become the second most common cause of death and the leading cause of ongoing disabilities worldwide [1, 2]. As stroke patients experience a loss of self-care ability, it is difficult for them to maintain their daily activities. It has become increasingly important to assist stroke patients to become more independent through post-stroke rehabilitation. Occupational therapy (OT) is one of the important treatment modalities for post-stroke rehabilitation. OT refers to the application of focused and selected occupational activities to prevent or recover the loss of various degrees due to physical, mental, and developmental dysfunction or disability [6]. It aims at helping patients become independent by improving their limb strength
