Most people react to the BioPulser® by saying, "oh, it's like a jack hammer." But that is only true if the BioPulser® is being used incorrectly. A jack hammer smashes passive hard material with concussion. Fortunately, the muscles are not passive material which can be pounded into pieces. Although some muscles may feel as hard as concrete, that hardness isn't the result of passive adhesion of particles, but really is an active state of over-contraction (excess muscles tone). Those muscles must be stimulated to relax, and not over-stimulated to contract even more as concussion would do. Unfortunately, such over-stimulation also triggers endorphin release which masks the resulting irritation and lulls many into believing the muscle was "forced" to relax.
The BioPulser® produces a sharp percussive motion-similar to the wrist snap which timpani drummers must develop in order to set the drum head into its resonant vibration. This gives the Biopulser the ability to set the taut, overly contracted muscles into their resonant vibrations. The muscle vibration is the therapeutic stimulation, not the percussion.
The Timpanist must also gauge the position of his hands so the mallets sharply tap the drumhead near the end of the strokes. If the mallets slam into the drumhead, they will squelch the resonant vibration. (The short loud sounds which result are sometimes musically desired.)
Unfortunately, the BioPulser® cannot do this gauging for you. This means you must stay engaged with how you are applying it. (Bummer) The muscle surface to which you need to gauge distance is hidden from view. So you have to rely on sounds and physical sensations to guide you.
Just as the Timpanist must "hover" over the drum, the BioPulser® must "float" over the hard muscle surface. The BioPulser® is "floated" on the skin and the properly relaxed overlying layers of muscle. The proper "float" depth along with the proper amount of stroke-limiting (gauging) washers (these are discussed later) will make the applicator tip tap the surface of the deeper overly contracted layers near the end of its stroke.
Rule #1: Floating the BioPulser®
In order to "float" the BioPulser®, it needs to be "dangled" by placing a thumb, finger or tripod handle (for self-treatment, ALWAYS use a tripod) in the inside radius at the tail-end of the handle. Do not allow any other fingers to also make contact or the BioPulser® will not freely dangle. The force of gravity is now borne by the digit or handle so the applicator tip operates free of gravity.
The timpano drum has a single timpanic membrane with a resonant frequency determined by its size and tautness. The overly-contracted muscle has multiple concentric layers of contracture with varying degrees of tautness from surface to core. The looser outer layers produce a lower pitch vibration which is felt as a fluttery sensation. The flutter of the muscle surface causes the applicator tip to make taps of varying intensity with each stroke. This produces a series of dull sounding "down-beat" clicks with relative quiet in between. You will not readily hear all of the fifteen strokes per second. The tauter muscle core resonates at a higher pitch with a steady, grumbly, sometimes tickling tremor sensation and a very audible hum. Well above 15 cycles per second.
Rule # 2: Maintain the "OK" Sounds & Sensations.
"OK" SOUNDS: Hear the well separated dull hollow clicking sounds of the percussion and the muscle core tremor hum & feel the muscle flutter and tremor sensations.
NO-NO: If you are penetrating too deeply with the "float" or there are insufficient gauging washers the applicator tip will impact the muscle instead of tapping it. This will cause a muscle jolt with every stroke of the BioPulser®. Hear the not so dull full fifteen clicks per second. You should easily detect that the clicks are now happening more rapidly with little separation. Feel the jolting is a very different sensation from the vibration.
OH NO!: If you penetrate even further, the jolts blend into a solid contraction which pushes the percussion into jack-hammer concussion. HEAR and FEEL the pounding.
Resist the temptation to lean-in in an attempt to increase the amount of vibration as it will often bring on the "no-no" sound. Instead, let the vibration build on its own as the muscles relax. You may have to eventually lean out slightly to give the increasing vibration room to move.
Rule #3: Practice: You should begin by practicing on yourself even if you plan to treat others.
The one we recommend is made by Dynex because of the handle size. The model is DX-TRP60. It is available at Best Buy.
