“…MA during lying and sitting is similar in both groups. Another study found significant higher EMG activity levels in static trunk muscles in individuals with SCI relative to healthy controls during tasks like sitting [32]. The present study did not find a difference between the ambulatory groups, possibly due to the muscle groups measured (mostly leg and back muscles instead of trunk muscles per se).…”

“…2 and 3) supports the view that clinically detectable sensory input from the lower limbs to the supraspinal structures was not required to achieve full weight-bearing standing without external assistance, and that sensory information projected to the human spinal circuitry plays a primary role in promoting motor patterns sufficient for standing. On the other hand, the lower neurological level of injury in the two individuals graded A compared with the two graded AIS B (Table 1) could have affected the level of trunk control 50 and hence contributed to the different standing ability. This speculation, however, needs further investigation.…”

Individuals affected by motor complete spinal cord injury are unable to stand, walk, or move their lower limbs voluntarily; this diagnosis normally implies severe limitations for functional recovery. We have recently shown that the appropriate selection of epidural stimulation parameters was critical to promoting full-body, weight-bearing standing with independent knee extension in four individuals with chronic clinically complete paralysis. In the current study, we examined the effects of stand training and subsequent step training with epidural stimulation on motor function for standing in the same four individuals. After stand training, the ability to stand improved to different extents in the four participants. Step training performed afterwards substantially impaired standing ability in three of the four individuals. Improved standing ability generally coincided with continuous electromyography (EMG) patterns with constant levels of ground reaction forces. Conversely, poorer standing ability was associated with more variable EMG patterns that alternated EMG bursts and longer periods of negligible activity in most of the muscles. Stand and step training also differentially affected the evoked potentials amplitude modulation induced by sitting-to-standing transition. Finally, stand and step training with epidural stimulation were not sufficient to improve motor function for standing without stimulation. These findings show that the spinal circuitry of motor complete paraplegics can generate motor patterns effective for standing in response to task-specific training with optimized stimulation parameters. Conversely, step training can lead to neural adaptations resulting in impaired motor function for standing.

“…At the same time, the knee joint has to bear a greater force, and sometimes the local part will suddenly be subjected to a greater impact force, especially when the knee joint is in a physiological and anatomical weakness. These huge impact forces will cause instantaneous damage to the knee joint or the strain of the adjacent structures around the knee joint (Wang Y J, Li J J, Zhou H J, et al 2016) [2]. The mechanism of knee joint is very complex, and the treatment and recovery after injury is a big problem.…”

Assessing the performance of basketball players is very important in the implementation of technical training programs. The application of electromyography (EMG) in basketball players is still relatively small. The evaluation of athletes’ muscle state index by EMG can guide sports training. This study used surface electromyography to test and compare EMG data, analyze muscle discharge timing, contribution rate and integral EMG value of the turning movement, aiming to explore the prevention mechanism of different types of injury affecting basketball players. The synchronous measurement model of EMG signal and plantar pressure curve in jump shot process of basketball players is established to deepen coaches’ understanding of jump shot movement rules and guide athletes to conduct scientific jump shot training. The research shows that the incidence of knee joint injury is relatively high in basketball players. Patella strain and softening, knee meniscus injury and cruciate ligament injury are the main types of injury, and there is no difference between genders.

Surface electromyography as a measure of trunk muscle activity in patients with spinal cord injury: a meta-analytic review

Abstract: This systematic review evaluated the value of trunk muscles for patients with SCI. We recommend use of SEMG as an assessment tool for improving the comparability and interpretability of trunk muscle activity of SCI therapeutic strategies.
