Single sensor wearable device for monitoring joint extension and flexion

A system for rehabilitation, comprising:

• a monitoring device comprising a memory device storing instructions and a network interface card, wherein the monitoring device is configured to detect information from a body part of a user;
• one or more processing devices operatively coupled to the monitoring device, wherein the one or more processing devices are configured to execute the instructions to:
• receive configuration information specified in a treatment plan for rehabilitating the body part of the user;
• receive the information from the monitoring device;
• and
• transmit the configuration information and the information to a computing device controlling an electromechanical device, via the network interface card;
• one or more pedals rotatably 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;
• and
• a control system comprising one or more processing devices operatively coupled to the electric motor, wherein the one or more processing devices are configured to:
• responsive to a first trigger condition occurring, independently drive the one or more radially-adjustable couplings to control the electric motor to operate in a passive mode;
• responsive to a second trigger condition occurring:
• measure revolutions per time period of the one or more radially-adjustable couplings;
• and
• when the measured revolutions per time period satisfy a threshold condition, cause the electric motor to drive the one or more radially-adjustable couplings to operate the electric motor in an active-assisted mode;
• and
• responsive to a third trigger condition occurring, to control the electric motor to operate in a resistive mode, provide resistance to rotation of the one or more radially-adjustable couplings.
