英文摘要
Project Summary
The long-term goal of this project is to develop a wireless, wearable system to estimate the
tension in tendons of the legs during dynamic movements. Tendon tension provides an estimate
of muscle force, which is important information for understanding biomechanical behavior in all
types of movement, though it has previously been difficult to measure. Recent advances have
shown that skin-mounted accelerometers can track the propagation of shear waves along a
tendon, after the waves are induced by a light mechanical tap on the tendon. The speed of
wave propagation depends on the tension in the tendon, so measuring wave speed provides a
measurement of tendon tension.
The proposed project will build and test a wearable system to make these tendon tension
measurements during free movement. These measurements promise to enable new methods of
injury assessment, rehabilitation, athletic training, and treatment of musculoskeletal disorders.
This research will investigate the ability of a mobile system to make measurements that match
the quality of laboratory systems, and the ability of tendon tension measurements to provide
insight into biomechanics during movement in everyday environments.
The Specific Aims of this project are to:
1. To design, build, and validate a wearable system for measuring tendon tension through
measurements of shear wave propagation speed in tendon.
2. To investigate the utility of wearable tendon tension measurements for assessing
biomechanical function during real-world activities.
