“…14 Decreased deep neck muscle stiffness may compromise the control of spinal movement. 59 Mechanically less precise muscle activation in people with chronic neck pain 49 and other chronic pain conditions 15,55 has been reported. In the current study, the reduced correlation with BMI, the large stiffness ranges, and higher stiffness during some tasks (overshooting) may be interpreted in line with a reduced mechanical precision of muscle use.…”

“…Measurements of the onset of muscle motion require higher temporal acuity than that provided by conventional B-mode ultrasound. M(otion)-mode ultrasound enables a temporal resolution of 1–5 ms 25 and permits the distinction of motion in superficial and deep muscle regions 7 26 27 . M-mode delineates the instantaneous positions of sound-reflecting tissue interfaces from a single ultrasound-beam which consecutively form a trace of displacement over time ( Fig.…”

Spatial variation and inconsistency between estimates of onset of muscle activation from EMG and ultrasound

Delayed onset of muscle activation can be a descriptor of impaired motor control. Activation onset can be estimated from electromyography (EMG)-registered muscle excitation and from ultrasound-registered muscle motion, which enables non-invasive measurements in deep muscles. However, in voluntary activation, EMG- and ultrasound-detected activation onsets may not correspond. To evaluate this, ten healthy men performed isometric elbow flexion at 20% to 70% of their maximal force. Utilising a multi-channel electrode transparent to ultrasound, EMG and M(otion)-mode ultrasound were recorded simultaneously over the biceps brachii muscle. The time intervals between automated and visually estimated activation onsets were correlated with the regional variation of EMG and muscle motion onset, contraction level and speed. Automated and visual onsets indicated variable time intervals between EMG- and motion onset, median (interquartile range) 96 (121) ms and 48 (72) ms, respectively. In 17% (computed analysis) or 23% (visual analysis) of trials, motion onset was detected before local EMG onset. Multi-channel EMG and M-mode ultrasound revealed regional differences in activation onset, which decreased with higher contraction speed (Spearman ρ ≥ 0.45, P < 0.001). In voluntary activation the heterogeneous motor unit recruitment together with immediate motion transmission may explain the high variation of the time intervals between local EMG- and ultrasound-detected activation onset.

“…Deficits in these stabilising muscles exist in GTPS (Allison et al , 2016a), including GMin and GMed (Woodley, Nicholson, 2008), however the detailed activation of these muscles is unknown. Using ultrasound, GMin has been shown to activate earlier in subjects with chronic hip pain during a step down function task (Dieterich et al , 2016), however there is no way of investigating amplitude of activation using this method. In the GTPS population, there is a lack of research into gluteal muscle activation during gait, despite walking being a common aggravator of lateral hip pain.…”

M-Mode Ultrasound Reveals Earlier Gluteus Minimus Activity in Individuals With Chronic Hip Pain During a Step-down Task

Abstract: Increased gluteus minimus motion during the swing phase and earlier gluteus minimus and superficial gluteus medius motion in individuals with hip pain suggest an overall increase of muscle activity, possibly a protective behavior.
