Abstract
Previous works in literature have indicated that pedaling movements are safe, effective and accessible to patients with a wide range of motor impairments. Recent research in the field of rehabilitation has shown that patients with stroke and cerebral palsy may improve their motor and balance abilities after an early short duration of pedaling training. In this work, a novel low-cost Motor Exercise Static Bike (MESB) has been enhanced by incorporating a Raspberry Pi 3B. The enhanced MESB includes custom-made hardware and software for allowing a user to command it, in addition, to monitor its operation through a Graphical User Interface (GUI). The GUI was programmed in Python 3.5 and was tested on Ubuntu 16.04 and Raspbian (rel. 2017-09-08) operating system. An Inertial Movement Unit (IMU) was selected in order to acquire both bike’s angular velocity and position data. The angular velocity was measured in degrees per second (DPS) directly from the IMU’s gyroscope z-axis, and the angular position was calculated by integrating the angular velocity over time.
