“…Importantly, asymmetries can lead to muscle imbalances, a decreased power output, and an increased risk of injury. In order to study an athlete's muscle activity, specialists usually use electromyography (EMG), which is useful to help detect neuromuscular abnormalities [51][52][53]. Usually, movement asymmetries caused by an injury can be seen with the naked eye.…”

Asymmetry plays a major role in biology at all scales. This can be seen in the helix of DNA, the fact that the human heart is on the left side, or that most people use their right hand. A single protein such as Myosin 1D can induce helical motion in another molecule. This causes cells, organs, and even entire bodies to twist in a domino effect, causing left–right behaviour. More generally, athlete movements are often asymmetric and, during the physical rehabilitation after injury, the asymmetry is visually discernible. Herein, we review the molecular basis of the movement asymmetries and report on the available knowledge on the few therapeutics investigated so far such as meloxicam. From a more rehabilitative perspective, it is very important to use effective methods to control the process of resolving the injury-related movement asymmetry through the complex use of specialised exercises, measurements, and gait analysis, which can all provide useful information on the effectiveness of the rehabilitation plans. If for each athlete, the normal range of asymmetry is known, the asymmetry can be individually treated and the evolution can be monitored over time. Appropriate measures should be taken if the movement asymmetry is outside this range. In addition, genetic, physiological, and psychological factors relevant to athlete health should be considered in the process of assessing and improving exercise asymmetry, which we also discuss in this review. The main proposal of this work is that the movement asymmetries in athletes should be individually treated, while taking into account the athlete’s genetics, physical condition, and previous injuries.

“…Of course, measurement results depend on the physical condition of the athlete: rested or tired, having muscle imbalance or dysfunction or not, etc. In order to study the athlete's muscle activity, specialists usually use electromyography (EMG), which is useful to help detect neuromuscular abnormalities [51][52][53]. Usually, movement asymmetries caused by an injury can be seen with the naked eye.…”

“…Among these techniques, surface electromyography (sEMG) provides electrophysiological measurements of muscles and can be used as neurorehabilitation control signals and assessment tools of neuromuscular functions [8]. Though EMG has been widely applied in stroke-related neurorehabilitation, EMG-based lower limb asymmetry assessment was not extensively applied when compared with other techniques based on motion capture, reaction force, or pressure measurements [9,10]. Lower limb movements require complex sensorimotor integrations with multiple spatial and temporal scales.…”

This study examines pedaling asymmetry using the electromyogram (EMG) complexity of six bilateral lower limb muscles for chronic stroke survivors. Fifteen unilateral chronic stroke and twelve healthy participants joined passive and volitional recumbent pedaling tasks using a self-modified stationary bike with a constant speed of 25 revolutions per minute. The fuzzy approximate entropy (fApEn) was adopted in EMG complexity estimation. EMG complexity values of stroke participants during pedaling were smaller than those of healthy participants (p = 0.002). For chronic stroke participants, the complexity of paretic limbs was smaller than that of non-paretic limbs during the passive pedaling task (p = 0.005). Additionally, there was a significant correlation between clinical scores and the paretic EMG complexity during passive pedaling (p = 0.022, p = 0.028), indicating that the paretic EMG complexity during passive movement might serve as an indicator of stroke motor function status. This study suggests that EMG complexity is an appropriate quantitative tool for measuring neuromuscular characteristics in lower limb dynamic movement tasks for chronic stroke survivors.
