SPIDER-CHAIR

New patented ergonomic concept.

About

The Spider-Chair is a dental stool made by a dentist for dentists, hygienists and dental assistants, as well as for all people working in a static sitting position (aesthetic, tattoo, health, hairdressing, podiatry, etc.). It helps in eliminating muscular stress and preventing musculoskeletal disorders.

Four out of five people are suffering or will suffer from back pain in their lifetime. This applies especially to workers who have to keep a difficult position for long periods of time, such as dentists and hygienists: using precision, while leaning over a patient, can bring its share of back pain at the end of the day. The Spider-Chair was made to counter this problem. In order to verify the efficiency of this stool, we several subjects, by placing electrodes on specific locations on the surface of their skin; then, using an electromyograph, we measured muscular contraction from these various areas. The parameters that we have analyzed are the signal analysis acquired from maximal voluntary and involuntary contractions during the usual work of a dentist in a sitting position. The following charts show the difference between a stool without a thoracic rest and a stool with a thoracic rest.

We can observe that using a thoracic rest significantly reduces muscular contractions from the various groups of muscles that were tested. In conclusion, surface electromyography used in the study clearly shows that the chair with a thoracic rest significantly reduces muscular contractions in the lumbar, thoracic, trapezius and quadriceps areas, reducing fatigue of the subject tested.
