Background:
Surface electromyography (sEMG) can provide information on muscle activation patterns during gait.
Objectives:
To characterize electromyographic activity during gait in shallow water and during deep-water running compare to on land and to review and analyse underwater surface-electromyographic (sEMG) procedures.
Search Methods:
Eight databases (MEDLINE, EMBASE, WEB OF SCIENCE, SPORT Discus, CINAHL, SCOPUS, SCIELO, and LILACS) were searched from their inception to the December of 2019.
Selection Criteria:
The selected studies had to be related to electromyographic analysis of gait in an aquatic environment.
Data Collection And Analysis:
The studies that met the inclusion criteria were reviewed by two independent reviewers and divided into four groups.
Results:
Ten studies met the inclusion criteria. Lower muscle activation was found with treadmill water walking compared to treadmill land walking. With deep-water running, the leg muscles (tibialis anterior and gastrocnemius lateralis) have lower muscle activation when compared to on land running, but the trunk and thigh muscles have higher activation.
Conclusion:
If gait is performed on an aquatic treadmill, the muscles assessed had lower muscle activation when compared to land. During deep-water running activities, lower activation of the distal leg muscles and a higher activation thigh muscles were found when compared to on land. Studies did not follow standard processes in sEMG procedures.
