This paper describes a single subject case study designed to evaluate the clinical usefulness of Differential Compliance Methodology employing the PulStarFRAS instrumentation. The results of the study illustrate the effectiveness of multiple impulse percussive force application in the release of fixations of spinal joints, where fixations were identified by compliance readings obtained with the PulStarFRAS. Over a progression of three weeks, the patient experienced a change in cervical curvature from a radius of 150 cm to 15 cm, as well as resolution of presenting symptoms.  Moreover, a restoration of normal cervical hard tissue compliance was recorded. Based on the results of the study, Differential Compliance Methodology including multiple impulse force application using the PulStarFRAS can be considered to have been an effective intervention in the care of the patient studied, who exhibited signs of spinal fixation with accompanying musculoskeletal dysfunction and other symptoms.
