Postural equilibrium: functional system and its stabilization by means of osteoreflexotherapy.
1998
Our investigations have confirmed that the osteoreceptive sensory system participates in the polysensoric regulation of animal and human posture. Experiments with animals have demonstrated that the irritation of osteoreceptors by electric pulses leads to osteoreceptive response potentials of the same parts of the brain (Deiter's nuclei, cerebellum, caudate nucleus, cortical motor centre etc.) which participate in the regulation of animal and human posture and other motion acts. Close functional relations have been established between the skin, bone, vestibular and muscle sensory systems in the brain structures where the osteoreceptive excitation converges. The studies of osteoreceptive sens…
Muscular synergies during motor corrections: investigation of the latencies of muscle activities.
2010
To reduce the complexity of muscular control, a small number of muscular activations are combined to produce an infinity of movements. This concept of muscle synergies has been widely investigated, mainly by means of principal component analyses (PCA) in the case of unperturbed movements. However, reaching movements can be altered at any time if the target location is changed during their execution. In this case, PCA does not precisely measure the latencies of muscles activities. We develop here a simple method to investigate how a random target jump toward a single location induced motor corrections in the whole musculature by precisely determining the latencies of muscle activities during…
Effect of the pacing strategy during half-duration resistance test on the mechanic, metabolic and cardio-respiratory response
2017
Objective: Changes in pacing rhythm are translated into functional and metabolic changes that can be significantly reflected in the final results of an athlete. Method: Ten male subjects, with moderate performance level (age: 25.2 ± 2.2 years; VO2max: 56.9 ± 5.7 ml kgâ1 minâ1), performed four 5-min races with different pacing strategies: constant-pace (CP), record-pace (RP), kicker-pace (KP), incremental-pace (IP). Results: The cardio-respiratory response did not show statistically significant. There were statistically significant differences (p â¤Â 0.05) in the energetic efficiency among the protocols CP vs. RP, CP vs. KP and RP vs. IP. When results were analyzed by partials (1-m…
Integration of GMR sensors with different technologies
2016
Less than thirty years after the giant magnetoresistance (GMR) effect was described, GMR sensors are the preferred choice in many applications demanding the measurement of low magnetic fields in small volumes. This rapid deployment from theoretical basis to market and state-of-the-art applications can be explained by the combination of excellent inherent properties with the feasibility of fabrication, allowing the real integration with many other standard technologies. In this paper, we present a review focusing on how this capability of integration has allowed the improvement of the inherent capabilities and, therefore, the range of application of GMR sensors. After briefly describing the …
The Tongue, Mandible, Hyoid System.
2017
The craniocervical-mandibular system works in harmony and allows different functional tasks as the postural control of the cervical region. This system is formed by the temporomandibular joint, the masticatory muscles and ligaments connecting the temporomandibular joint and the cervical region. It has been seen to affect human posture, and many disorders of the temporomandibular joints may affect this functional arrangement. Notwithstanding this system considered as a functional arrangement, may offer various clinical explanations, it does not hold anatomical connections with the posterior region of the cranium, thus it should not be refered to as a craniocervical arrangement. For this reas…
