“…It may be interesting, for physiotherapists, to determine, when possible and in real time, IMA variations consequent to the shifting of patients’ postures (from supine to a seated position), different seated postures (with aids and supports), or from a sitting to a standing position. In addition, the amount of IMA can be used as an outcome in the assessment of the effectiveness of physiotherapy treatments aimed to maintain muscle length and extensibility, such as stretching protocols and manual therapy treatments [ 14 , 16 , 36 , 37 ].…”

Sustained involuntary muscle activity (IMA) is a highly disabling and not completely understood phenomenon that occurs after a central nervous system lesion. We tested the feasibility of in-field IMA measuring at an acute rehabilitation ward. We used wearable probes for single differential surface EMG (sEMG), inclusive of a 3D accelerometer, onboard memory and remote control. We collected 429 h of data from the biceps brachii of 10 patients with arm plegia. Data quality was first verified in the time and frequency domains. Next, IMA was automatically identified based on the steady presence of motor unit action potential (MUAP) trains at rest. Feasibility was excellent in terms of prep time and burden to the clinical staff. A total of 350.5 h of data (81.7%) were reliable. IMA was found in 85.9 h (25%). This was often present in the form of exceedingly long-lasting trains of one or a few MUAPs, with differences among patients and variability, both within and between days in terms of IMA duration, root mean square (RMS) and peak-to-peak amplitude. Our results proved the feasibility of using wearable probes for single differential sEMG to identify and quantify IMA in plegic muscles of bedridden acute neurological patients. Our results also suggest the need for long-lasting acquisitions to properly characterize IMA. The possibility of easily assessing IMA in acute inpatients can have a huge impact on the management of their postures, physiotherapy and treatments.

“…When combined with the acupoint injection of O3, this therapy has even more beneficial effects [70]. Pradines et al [71] reported that guided self-rehabilitation, combined with conventional rehabilitation, increased muscle fascicle length, extensibility, and ambulation speed more than conventional rehabilitation alone in patients with chronic hemiparesis. Atan et al [72] reported that body weight-supported treadmill training improved walking distance and balance ability, relieved fatigue, and also reduced pain in patients with moderate to advanced PD.…”

Time is infinite movement in constant motion. We are glad to see that Neurorestoratology, a new discipline, has grown into a rich field involving many global researchers in recent years. In this 2019 yearbook of Neurorestoratology, we introduce the most recent advances and achievements in this field, including findings on the pathogenesis of neurological diseases, neurorestorative mechanisms, and clinical therapeutic achievements globally. Many patients have benefited from treatments involving cell therapies, neurostimulation/neuromodulation, brain–computer interface, neurorestorative surgery or pharmacy, and many others. Clinical physicians can refer to this yearbook with the latest knowledge and apply it to clinical practice.

“…In addition, the volume, moment, and activation of the plantar flexor muscle of stroke survivors were all lower than that of healthy adults, and fascicle lengths and extensibility were decreased due to stiffness [3,9]. A previous study showed that stretching the lower limb muscles, including the plantar flexor muscle, improved ambulation speed and the structural changes in the muscle [9]. However, there are only a few studies that examine how this altered muscle structure affects physical function.…”

“…In particular, chronic stroke survivors with a gait speed slower than 0.8 m/s showed thinner quadriceps muscle thickness and the worst static balance compared to healthy adults [8]. In addition, the volume, moment, and activation of the plantar flexor muscle of stroke survivors were all lower than that of healthy adults, and fascicle lengths and extensibility were decreased due to stiffness [3,9]. A previous study showed that stretching the lower limb muscles, including the plantar flexor muscle, improved ambulation speed and the structural changes in the muscle [9].…”

“…Most of the studies involving the stroke population have focused on strengthening the overall lower extremity muscle strength and changing the gait pattern using various environments such as robots and virtual reality [6,8,[17][18][19]. Recently, with emerging knowledge about the importance of the triceps surae, various studies have reported improvement of function in patients with stroke through eccentric contraction or stretching of the triceps surae [3,9,13,20]. However, studies comparing the triceps surae and the tibialis anterior (TA) at the muscle level using ultrasound images in patients with stroke and studies examining the relationship among functional movements are insufficient.…”

Objective: This study aimed to compare muscle structure, balance, and gait parameters between healthy adults and persons with stroke and to analyze the correlation among these variables. Design: Cross-sectional study. Methods: Twenty persons with stroke (11 male, 9 female) and twenty healthy participants (9 male, 11 female) were included. Ultrasound images of the triceps surae and the tibialis anterior were acquired in sitting resting, sitting co-contraction, and standing resting positions and also during the functional reach test (FRT) and single leg anterior reaching test (SLART). Muscle thickness and fascicle length were measured. Spatiotemporal parameters of gait were measured using a pressure walkway. Gait speed, cadence, step length, stride length, stance time, and swing time were measured. Results: Changes in percent fascicle length were significantly greater in the gastrocnemius and soleus (SOL) muscles of healthy adults in the sitting co-contraction position (p<0.05). The percent fascicle length of the SOL in FRT and SLART were significantly greater in healthy adults (p<0.05). The mid-stance phase of stroke patients was shorter than healthy adults (p<0.05). A negative correlation was observed between percent fascicle length of the SOL in the sitting co-contraction position and the proportion of the mid-stance phase (p<0.05). Conclusions: The function of the triceps surae is affected in persons with stroke when compared with healthy adults. This can lead to difficulty in performing tasks that involve forward transfer of weight. If the triceps surae is not sufficiently secured, the possibility of compensation in the stance phase increases during gait.
