Monitoring Joint Extension and Flexion Using a Sensor Device Securable to an Upper and Lower Limb

A system for rehabilitation, comprising:

• an electronic device having a housing configured for attachment to a user, wherein a sensor, and a processor are disposed within the housing;
• and
• a processing device operatively coupled to the sensor, wherein the processing device is configured to:
• determine one or more angles;
• and
• transmit the one or more angles to a computing device controlling an electromechanical device, the electromechanical device comprises:
• one or more pedals coupled to one or more radially-adjustable couplings;
• an electric motor coupled to the one or more pedals via the one or more radially-adjustable couplings;
• a control system comprising one or more processing devices operatively coupled to the electric motor, wherein the one or more processing devices are configured:
• responsive to a first trigger condition occurring, by independently driving the one or more radially-adjustable couplings rotationally coupled to the one or more pedals, to control the electric motor to operate in a passive mode;
• and
• responsive to a second trigger condition occurring by:
• measuring revolutions per time period of the one or more radially-adjustable couplings, and
• when the measured revolutions per time period satisfy a threshold condition, causing the electric motor to drive the one or more radially-adjustable couplings rotationally coupled to the one or more pedals, to control the electric motor to operate in an active-assisted mode.
