本文研究了41名正常健康受试者学习分离和控制右二头肌单个运动单位的能力，以及冰敷在这块肌肉上的皮肤区后这种习得反应的变化。肌电记录运动单位活动。78%的受试者能够熟练地分离和控制一个运动单位，其中60%的受试者在应用冰后表现出促进运动单位活动的能力。这种促进表现为在发出停止命令后过度发射隔离的单元，或者通过在附加的运动单元的背景上叠加的隔离的运动单元的激活和控制的改变来体现。
The ability of forty-one normal healthy subjects to learn to isolate ancl control a single motor unit in the right biceps brachii muscle, and the subsequent alterations in this learned response after ice application to the skin area overlying this muscle have been investigated. Motor unit activity was recorded electromyographically. Seventy-eight percent of the subjects were able to skillfully isolate and control one motor unit and 60 percent of these subjects exhibited facilitation of motor unit activity after the application of ice. This facilitation was manifested by excessive firing of the isolated unit after a stop command was given, or by alterations in the activation and control of the isolated motor unit superimposed on a background of additional motor units.
