![]() ![]() Upper extremity function was measured with the Nine-hole peg test, upper extremity strength (shoulder flexion-abduction, elbow flexion, pinch and grip) with hand-held dynamometer, hand grip dynamometer and manual pinch meter, threshold of light touch-pressure with Semmes-Weinstein monofilament, duration of vibration with 128-Hz frequency tuning fork, and distance of two-point discrimination with an aesthesiometer. Twenty-two patients with MS (mean age: 38.5 ± 8.31 years, median Expanded Disability Status Scale (EDSS): 2) and 10 healthy subjects were included. #512 tuning fork freeTake a look around, get (or give) new ideas, and feel free to call or email us with any questions.The purpose of this study was to investigate the relationships between the upper extremity functions, upper extremity strength and hand sensation in patients with Multiple Sclerosis (MS). Pouches are available with 2, 4 or 8 pockets. Longer handles are 2.75" to 3" and can be added for an additional charge of $7.99 per tuning fork.Īccessories: Add activators, striking hammers or mallets to enhance the resonance of the tuning forks, or a heavy fabric pocket pouch for convenience and protection of your tuning forks.

Weights are an option on tuning forks above 100 Hz but we do not recommend weights frequencies above 500 Hz.) ![]() (Tuning forks from 30 Hz to 99 Hz have weights added by default. The additional charge is $7.50 per per Tuning Fork. ![]() Weights: Weights can be added to each fork. Custom engraving is also available for additional charge. Packing: Each tuning fork is sealed in plastic wrap and placed in a lightweight pouch or carry bag.Įngraving: Each tuning fork is engraved with its' own Hz. Even greater accuracy is available on special order. Each and every tuning fork is quality tested before leaving the lab to guarantee accuracy to within. However, we can manufacture tuning forks to any frequency from 30 Hz to 6000 Hz to two decimal places.Īll of our tuning forks are American-made from a patented aluminum alloy designed specifically to produce tuning forks with the highest degree of pitch accuracy, the purest quality of tone, and longest lasting ring-time at an affordable price. We list some of the more popular frequencies used in Music, Science, Healing, Hearing, Medical testing, Education, Science, Sound therapy, Tuning, Calibration and more in our regular inventory. In addition to the Verdi Tuning Forks, we offer Tuning Forks at any other pitch (frequency) that you may require for your specific application. We Specialize in Custom Forks To Meet Any Challenge – From 30 Hz to 6000 Hz Giuseppe Verdi, by 1884, recognizing the damage to the singers and instruments due to arbitrary higher tuning over the years, introduced a law, corresponding to natural law, to protect the health of singers’ voices: that the standard musical pitch for A (“La”) be set at 432 Hz, and absolutely no higher. These tones, their octaves, and the scale derived from them are determined by the natural, harmonic and physiological characteristics of the human singing voice, beautifully developed by Classical Music composer J.S. Verdi Tuning Fork is the designation, unique to SWB 256 Tuning Forks, which identifies our tuning forks centered on the well-tempered scale of Middle-C at 256 Hz to the octave above, C at 512 Hz, with the A at 432 Hz.
