SIGMA Instruments manufactures a full line of computer-based, piezoelectric instruments that utilize an accelerated mass in the head of the instrument to gently percuss the tissue area being tested, giving the practitioner vital information about the motion dynamics and resonant frequency of the joint or tissue.The SIGMA instrument measures the stiffness of the tissue or joint by applying a light mechanical force in the form of an instantaneous shock wave and oscillating frequency; a signal is then reflected back to the piezoelectric sensor, which measures these reflective statistics, sending it to the computer for interpretation, all before the muscle can respond. The process occurs so fast that it reduces the normal defense mechanism or guarding response, caused by typical palpation.
SIGMA Instruments uses the same sensing technology that the aviation industry and engineers have used in order to test metal fatigue in aircraft and bridge spans.Practitioners can now use this highly sophisticated technology to analyze joints and tissue with increased precision and confidence.
With this technology, musculoskeletal conditions can be managed by increasing range of motion, eliminating fixation and improving functional capacity of patients through specific manipulative techniques assisted by the instrument in a precise and reproducible manner. The SIGMA Instrument enables the practitioner to analyze using a sophisticated instrument, treat the dysfunctional area and then reanalyze. This provides pre and post data which is very beneficial while overseeing the patient's course of care. It provides a method to track treatment progression that is precise, gentle and preferred.
The SIGMA Instrument virtually puts all the fears of manual treatment to rest. The SIGMA Instrument utilizes a precise oscillating force with uninterrupted motion. It is able to increase mobility of the spinal segments by reducing or eliminating the fixations. It uses soft tips, that are comfortable to the human body to exert a tapping force that "unsticks" the joint.
1 Soft Tissue conditions such as triggerpoints respond well to the percussion forces of SIGMA Instrument. The forces are delivered in a sub-harmonic, metered, precise nature to create oscillation and enhance range of motion.
2 Neurologically, the SIGMA Instrument takes advantage of the interplay of the type 1, 2, and 3 mechanreceptors with the type 4 nociceptors creating an inhibition of pain, increasing neuroactivity and restoration of normal nervous system tone.
3 The SIGMA Instrument is very comforable for patients of all ages due to the fact that there is no application of manual rotation or thrusting forces.
4 The patient is treated in a comfortable way without the need to turn or hyperextend parts of the body, head or neck. Thus this greatly reduces any issues associated with osteoporosis, vertebral artery conditions or other concerns that more aggressive techniques might not address.
