![]() SURTEX® Instruments manufacture Koenig tuning forks from the finest quality of stainless steel to provide trustworthy service in your otology and neurology examinations. Ensure the patient can feel the vibration. Another reference sensation can be elicited by placing the vibrating fork on the edge of the big toenail. Using a 128 or 256 Hz tuning fork, place it at a distal joint (typically the interphalangeal joint of the great toe). SURTEX® Instruments manufacture Koenig tuning forks from the finest quality of stainless steel to provide trustworthy service in your otology and neurology examinations. application of the tuning fork to the patient. To stop the vibrations, just place the prongs in your closed palm. A tuning fork is a fork-shaped acoustic resonator used in many applications to produce a fixed tone. To do that, place it on the patient’s sternum or the base of the toe. Altogether, the graduated tuning fork represents a simple and reliable alternative to quantitate vibration sensations. ![]() Therefore, if you set the damper at the A mark, it produces a frequency of 109 Hz.Īlso, you can use this tool to examine for vibration sense. Within-test variation at big toes reached 8.4 in diabetic patients vs. Following that, place the base on the mastoid to test bone conduction.įurthermore, the two prongs have adjustable dampers from A to g. To find a simple and reliable means to measure vibration sensations, 189diabetic patients and 88 control subjects were tested at different sites with a graduated tuning fork. Then, place the prongs at right angles to the ear to test air conduction. To produce vibrations, hold the foot and strike the prongs on a hard surface. These preliminary findings are based on a small sample size. ![]() It is set in vibration by means of a wooden rod. In addition, they evaluate vibration sensation during nerve examinations.įor optimal performance, the ratios of the shoulder, stem and plastic foot of this fork ensure balance and control. This study suggests that assessment of vibration sensation with the tuning fork may be unreliable. Charcot provides the following account of tuning fork trials, which were conducted on patients whose minds and bodies were particularly susceptible to suggestion: The patients are seated over the sounding box of a strong tuning fork, made of bell metal, vibrating 64 times in a second. To test vibration sense, the examiner places a finger under the patient’s distal interphalangeal joint and presses a lightly tapped 128-cycle tuning fork on top of the joint. SURTEX® Koenig Tuning Forks help doctors to examine the ear and test for different types of hearing loss.
