Abstract: 
The motive reaction of fingers of an upper human limb under the condition oF changing blood supply of working muscles through the pneumatic influence on a shoulder artery (using a cuff) is investigated. A pressure increase in the cuff accompanied by fingers blood supply reduces results in dynamogram amplitude decreasing and replies maximum shifting to lower frequencies. The direct connection between the capacity for work of limb fingers and their blood supply level has been ascertained.
