[Several functional and diagnostic criteria in the evaluation of the state of the neuromuscular function of arms of workers exposed to the effects of local vibration].
The authors studied neuromuscular apparatus of hands in workers subjected to local vibration and in patients having vibration disease (VB). If compared to apparently healthy individuals both exposed to vibration or not, the VB patients proved lower muscular durability (MD) of hands, higher oxyproline excretion (OB) and greater MD/OB ratio. The studied parameters (MD, OB, MD/OB) in the VB patients turned out to be similar in the VB patients and the healthy examinees having initially low MD (under 29 s). The suggested criteria were recommended for early diagnosis of neuromuscular disturbances in hands and for occupational selection.
