ABSTRACT:
A non-invasive method and apparatus for determining the dynamic biomechanical characteristics (frequency response functions and natural frequency) of a musculoskeletal structure is provided. The method generally comprises exciting the musculoskeletal structure over a broad range of frequencies with a low amplitude, high velocity impulsive input force, measuring the input force with a force transducer, detecting the output motion response with an output transducer, processing input force and output response data into time-signal histories with a data acquisition and analysis means or digital computer, transforming the time-signal histories from the time domain to the frequency domain by applying Fourier analysis; and calculating a frequency response function and the natural frequency from the input force and dynamic output response time-signal histories. Having identified the natural frequency of the musculoskeletal structure, the clinician can then mobilize the structure at that frequency in order to maximize the effectiveness of spinal therapy. The apparatus comprises an impact device, an input transducer, an output transducer, and a data acquisition and analysis means or digital computer. In particular, a hand-held, manually operated impact device for delivering a near optimal, low amplitude, high velocity, impulsive input force over a broad range of frequencies and characterized by a generally half-sinusoidal waveform is also provided.
