[Diagnostic method in occupational vegetative trophic dysfunction of upper limb muscles]

The investigators registered the curves of force and quickness in digital compression of transducer during 30 s at rate of 80 per minute. Force and quickness at the certain moments of the movements were measured, times of contraction and relaxation were estimated. The method enables to assess the parameters of muscular contractility, compare them and evaluate the functional state. Lower quickness of contraction is known as the first sign of muscular fatigue. The method is applicable in workshops, handy and fit for mass screening, enables to assess influence of work conditions on the worker's hands. The method is certified by an Authorship No 1683682.
