The vestibular system is critical for human locomotion. Any deteriorated leads to gait instability. In the past decades, these alternations in patterns have been majorly measured by spatial-temporal parameters and respective variabilities. However, measuring characteristics cannot capture full aspect of motor controls. Thus, further understand effects on performance, additional measurement needs be taken into consideration. This study proposed using margin stability (MOS) identify dynamic...

Background: Anatomical differences between sexes in the vestibular system have been reported. It has also demonstrated that there is a sex difference balance control while standing on vestibular-demanding tasks. In 2024, NASA expects to send first female Moon. Therefore, extend current knowledge, this study attempted examine whether different respond differently vestibular-disrupted and environments. Method: A total of fifteen males females participated study. The function was quantified...

Walking on an incline demands specific neuronal control because the vestibular system may alter gait patterns to maintain balance with respect self-orientation gravity. A previous study confirms aforementioned hypothesis that walking inclines bilateral disruptions altered spatial–temporal parameters in anterior–posterior and vertical directions. This extended current knowledge investigate mastoid vibration's effect Margin of Stability (MoS) while inclines. Eighteen healthy young adults...

This study aims to investigate the differences in pelvic floor dysfunction (PFD) and diastasis recti abdominis (DRA) between primiparous second-parous females with known risk factors controlled. 49 age-matched postpartum after spontaneous vaginal delivery were included October December 2023. Independent variables include weight, height, body mass index (BMI), fetal gestational weight gain (GWG). Main outcome measurements resting pressure (VRP) maximum voluntary contraction (MVCP) indicating...

Abstract Ageing‐related sensory deteriorations are significantly associated with poor balance control among older individuals, resulting in a higher risk of falling dark environment. In particular, the proprioceptive system plays critical role maintaining balance. This study aimed to determine how ageing‐related contributed during standing under various conflicts. Twenty healthy, active adults (10 young and 10 older) participated this study. Balance was quantified through two organization...

Background Sensory-motor perturbations have been widely used to assess astronauts’ balance in standing during pre-/post- spaceflight. However, control walking, where most falls occur, was less studied these astronauts. A study found that applying either visual or platform oscillations reduced the margin of stability (MOS) anterior-posterior direction (MOSap) but increased MOS medial-lateral (MOSml) as a tradeoff. This tradeoff induced an asymmetric gait. extended current knowledge...

Abstract Forty-seven percent of falling accidents in older adults are caused by tripping over obstacles. Understanding what strategies involved obstacle negotiation could reduce fall risks. There is a paucity research investigating how healthy negotiate multiple obstacles, which may better reflect the complexity real environment. The presence second has induced mixed results with interval between obstacles two steps apart. This study extended knowledge to understand younger and used step...

Most falls might be attributed to an unexpected perturbation such as a slip. It aggravated by the deterioration of sensory system people aged. This increases demand in active control. However, what levels control do older adults need? study aimed answer this question using novel assessment. Both young and old walked three conditions: normal, slip, slip with low light conditions. The amount step length variability, width 95% confidence interval ellipse area heel contact locations was measured...

Background: Sensorimotor training using visual perturbations has been widely applied to astronauts for rapidly handling and adapting unpredictable environments. However, these might not be strong enough trigger long-term effects. Therefore, this study aimed develop a novel sensorimotor paradigm pseudo-random determine the demands patterns of active control under different types perturbations. Method: Thirty healthy young adults participated in study. Four walking conditions were randomly...

Background Plantar vibration has been widely used to strengthen the sensation of somatosensory system, further enhancing balance during walking on a level surface in patients with stroke. However, previous studies plantar only involved surface, which neglected importance inclined/declined daily life. Thus, combining and might answer critical research question: whether different types had effects gait characteristics inclines. Methods Eighteen healthy young adults were recruited. Fifteen...

Modern surgical practice often requires multitasking in operating rooms, generally full of distractions. The purpose this research was to investigate the effect distraction on robot-assisted skill performance medical students and residents.Fourteen subjects performed a suture-tying task with da Vinci(™) system distractive secondary tasks simultaneously. time completion, speed total distance travelled were analysed. Two-way repeated-measures ANOVA applied. scores analysed.A significant found...

State-of-the-art three-dimensional motion analysis systems, which are utilized to predict, diagnose, and treat many musculoskeletal neurological disorders, expensive space consuming. These systems have only been widely used in large research facilities because of their lack this transportability. Since device portability is a critically important the military, most small military hospitals therefore deprived these systems. The purpose study was develop mobile capture system, MO2CA,...

Eighty-eight percent of the persons with bilateral vestibular dysfunction have reported at least one fall within past 5 years. The apparent alternations due to dysfunctions (BVD) are gait characteristics, such as slower walking speed, prolonged stance phase, and shorter step length. Unexpectedly, prevalence this BVD being relatively low, attention is not obtained same in other disorders. Moreover, how does on different inclines, part daily activities, alter characteristics under unreliable...

Controlling surgical task speed and maintaining accuracy are vital components of robotic skills. This study was designed to investigate the relationship between for robot-assisted skills.Ten participants were asked alternately touch two circular targets with various dimensions distances targets, using da Vinci Surgical System. The design this based on Fitt's law. Statistical correlations index difficulty (ID) movement time (MT), as well ID smoothness movement, analysed.A significant linear...

The mastoid vibration (MV) has been used to investigate unilateral vestibular dysfunction by inducing nystagmus. Additionally, this MV can be quantify the effect of deterioration aging on system during walking. Could such assess uni/bilateral standing?This study attempted determine feasibility using for identifying standing.Fifteen young and ten old adults' balance control patterns were assessed three random conditions: 1) No MV; 2) Unilateral 3) Bilateral MV. dependent variables 95%...
