Neuromotor diseases are leading causes of performance limitations in Activities of Daily Living (ADLs), with the evaluation of upper limb (UL) movement patterns being essential for patient rehabilitation. Evaluation methods often rely on subjective assessments, and existing biosignal equipment lacks a combination of essential features such as portability, synchronized muscle contraction monitoring, and range of motion. To bridge this gap, a prototype of a portable, low-cost device was developed to assess biomechanical and electrophysiological parameters, integrating electromyography (EMG) sensors and an inertial measurement unit (IMU). A pilot study with twelve individuals was conducted to monitor contraction patterns and range of motion in both ULs using the developed device. The objective of this article is to present the results of applying this device to characterize neuromotor patterns during a bilateral ADLs performed in healthy subjects, to understand human movement patterns.
