THE STUDY OF NEUROMUSCULAR ACTIVITY DURING MOVEMENT IN WATER

Abstract

Background and Aim: Since, the complex electromyographic signal (EMG) is controlled by CNS during muscle contraction and depends on physiologic and anatomic characteristics of muscle; it can be used in studying coordination and control of movement. Because of the relationship between quantities of EMG signal and muscle force, this technique has been used for studying the neuromuscular activity in postural tasks, functional movements, ergonomic conditions and training as well as clinical programs. Since motion in water has a special effect on muscle activity, and surface EMG is a great tool in recording and visualization of muscle activity. Its use has expanded among those who have a special interest in the effect of muscle motion such as researchers in the field of rehabilitation, sport and other areas related to biomechanics and kinesiology. With regard to the inherent differences between water and land, use of surface EMG is different. Challenges related to water proofing, sealing the electrodes and instruments when recording EMG signals for long duration is evident. In this review article, by examining different studies, challenges of recording EMG in water as well as various activities which have been examined by this method and their results will be reviewed. Searching for the articles was done on: EMG, Biomechanics, Neuromuscular activity, Aquatic Exercise in some related databases such as Pub Med, Science Direct and Mendely. Keywords: EMG, Biomechanics, Neuromuscular activity, Aquatic Exercise
