1]) is transferred to the MCP joint through the four bar linkages system.
Conventionally, it is acknowledged that the mechanical joints of wrist and index finger in the WDFHO should be located at the distal tip of the radial styloid and the radial side of the second MCP joint, respectively .
Based on the motor data sheets published by the motor manufacturer, the maximum torque that can be generated about the MCP joint for the iLimb is 0.
Individual finger flexion/extension speeds were measured about the MCP joint using an externally mounted potentiometer.
The Ab/Ad only occurs at each finger's MCP joint
and at the thumb's MCP and TM joints.
Prior to FDA PMA approval of the Ascension(R) MCP, the only implants approved for unrestricted use in the MCP joint
were single-piece silicone rubber spacers.
To measure the joint angles needed for the grasp prediction model, we positioned four bendsensing resistors (Flexpoint Sensor Systems, Inc; Draper, Utah) over the PIP and MCP joints of the thumb and index finger (Figure 3).
where [theta] = joint angle and d = distance between the origins of the thumb and index finger MCP joint base frame.
