Instrument adjusting
The number one concern of someone looking for a Chiropractor is, Will the Doctor find out why I hurt or having problems? A close second is does he have the skill to fix it and then the new number one fear is will it hurt? Using a precision computerized instrument can answer all these questions. It is meant to be precise, in measuring motion of an individual segment. It is calibrated to deliver correct impulse speed and resonance. In the hands of a trained Chiropractor it can provide the answer to what’s wrong, can it be fixed and will it hurt. The only variable left is your individual body’s capacity to heal.
If the body is self-healing and self-regulating then when pain occurs WHAT caused it? Dropping something heavy on your foot or cutting yourself is obvious. What about headaches? Ulcers? Low back pain when you didn’t lift or “overdo it? As chiropractors we have traditionally used touch and examination of structure for imbalance or spasm and then used our knowledge of neurological innervation to see if that tissue or organs corresponding nerve root is compromised .
Millions of Nerves travel through our nervous system both central and peripheral to control the functions of your body. Spinal segments that are out of alignment or not moving properly can affect your health by irritating spinal nerves. The pressure equal to the weight of nickel can inhibit nerve function 60%. When irritated, these nerves alert you that something is wrong. Symptoms, including pain, are usually the result. Nerve signals are also sent to your muscles to stabilize and protect the area. You may feel stiff, sore, and tired. Instead of taking pain masking drugs, which can be dangerous to your health, Chiropractic care seeks to locate the source of your symptoms and address the underlying cause, so the problem doesn’t get worse. Research has clearly shown that chiropractic adjustments result in both biomechanical and physiological responses in the human body.
Significant neuromuscular reflex responses in the adjacent and sometimes distant spinal musculature have been recorded in numerous studies (Herzog et al., 1999;Symons et al., 2000;Colloca et al., 1999;Colloca and Keller, 2000).
(Gillette R.G., 1987;Gillette R.G., 1986;Gillette et al., 1998).
Inasmuch, beneficial effects of chiropractic adjustments are thought to be associated with mechanosensitive afferent stimulation and presynaptic inhibition of nociceptive afferent transmission in the modulation of pain (Wyke, 1980;Willis W. and Coggeshall R., 1991), inhibition of hypertonic muscles (Thabe, 1986;Herzog, 1996), and improved functional ability (Meade et al., 1995;Shekelle, 1994;Triano et al., 1995).
For this reason, mechanical devices utilizing static and quasi-static oscillatory PA forces have been developed to more objectively quantify PA spine stiffness (Latimer et al., 1996;Latimer et al., 1998;Lee et al., 1997;Kawchuk and Herzog, 1996).
The reliability and validity of instruments to assess PA spine stiffness have shown favorable results (Latimer et al., 1996), (Latimer et al., 1998;Lee et al., 1997;Lee and Svensson, 1990;Viner and Lee, 1995).
Assessment of PA spinal stiffness to date however, have been primarily limited to study of asymptomatic subjects at low frequencies.
