Vibration Therapy: Desensitization and Circulatory Enhancement

Gate Control Theory

In order to understand this phase, it is important to understand the gate control theory. This theory states that throughout the nervous system of the human body are many types of nerve fibers responsible for relaying all the sensory information from our limbs, tissues, and organs to our brain. One type, collectively known as nociceptive nerve fibers, is responsible for providing us with the unfortunate sensation of pain. On the other end of the spectrum lie another group of nerve fibers known collectively as non-nociceptive fibers. These fibers provide information related to all non-painful stimuli; among which is vibration. By utilizing the vibratory feedback of the machine on a painful area, one can successfully assist in “closing the gate” and therefore reduce the level of pain being experienced by the individual. Ever bump your head and immediately start rubbing the area you bumped? How about shaking the area immediately after the trauma? Those are examples of you trying to “close the gate”.

How Vibration Therapy is Applied.

Through selective, carefully applied exposure (direct or indirect, depending on the area) of an injured region to the vibration platform, the significantly high level of vibratory information being absorbed by the individual’s body helps temporarily override the pain information being sent to the brain. The brief window of opportunity provided by this phenomenon, a window that can stay open for longer and longer periods of time with multiple treatments, allows the patient to increase their joint and tissue mobility, painlessly contract the muscles more forcefully, and tolerate what would otherwise be considered intolerable manual therapy treatment techniques. Additionally, through exposure to the vibration, local blood flow is increased to the region thus helping to further create a state of relaxation in the surrounding muscle and improve lubrication of the surrounding joints. In the clinic, success is best measured through subjective reports of pain (0-10 pain scale) and range of motion testing (how far a body part can move without pain). In most cases, these two measurements improve simultaneously. Next week I’ll discuss the second use of Vibration Therapy which is neuromuscular re-education.

Physics problem: Kinetics of Oscillation?

1. A vibration platform oscillates up and down with an amplitude of 11 cm at a controlled variable frequency. Suppose a small rock of mass m is placed on the platform. At what frequency will the rock just begin to leave the surface so that it starts to clatter?

X = a * sin (2 PI F t)

displacement = 11 , a = 11/2

V = 2 pi f a cos(2 PI F t)
acceleration = – 4 * pi * pi* f^2 a Sin(2 PI F t)

Max acceleration, sin = -1 > 1 g
980.6 cm/s/s = 4 * pi^2* f^2

f = sqrt(980.6/4/pi^2)
