Devices and methods for evaluating motion of a tissue location, such as cardiac tissue location, e.g., heart wall, are provided. Devices employed in the subject methods are fiberoptic tissue motion sensors that include a light guide having a reflective element at its distal end and a light emitter/detector at its proximal end. In embodiments of the methods, a signal obtained from reflective element stably associated with the tissue location of interest is employed to evaluate movement of the tissue location. The subject methods and devices find use in a variety of different applications, including cardiac resynchronization therapy.
