BackgroundData on functional and psychological side effects following curative treatment for prostate cancer are lacking from large, contemporary, unselected, population-based cohorts.ObjectiveTo assess urinary symptoms, bowel disturbances, erectile dysfunction (ED), quality of life (QoL) 12 mo after robot-assisted radical prostatectomy (RARP) radiotherapy (RT) using patient-reported outcome measures in the Swedish database.Design, setting, participantsThis was a nationwide,...

Abstract The ability to handle sensory conflicts and use the most appropriate information is vital for successful recovery of human postural control after injury. objective was determine if virtual reality (VR) could provide a vehicle training, temporal spatial nature such adaptive changes. Twenty healthy subjects participated in study (10 females). watched 90-second VR simulation railroad (rollercoaster) motion mountainous terrain during five repeated simulations, while standing on force...

The aim of this study was to investigate the significance information from plantar cutaneous mechanoreceptors in postural control and whether could compensate for reduced by adaptation. Sixteen healthy subjects were tested with eyes open or closed hypothermic normal feet temperature during posturography where body sway induced vibratory proprioceptive stimulation towards both calf muscles. anesthesia obtained cooling subject's ice water 20 minutes. Body movements evaluated analyzing...

AbstractThe aim of this study was to analyze the composition sway in adults and "healthy" elderly people evaluate influence vibration sensation asymmetric vestibular function on pattern. Ten with a mean age 37.5 years 40 healthy senior citizens 74.6 living independently community were studied. Vibration-induced body measured force platform. The analyzed separated into its high low frequency components above below 0.1 Hz, respectively. Additionally subjects observed for occurrence spontaneous...

In Brief Study Design. Exploratory experimental design. Objectives. To examine primary and coupled cervical movements, to study the effects of age, gender, body mass index in a "neck-healthy" population. These data could serve as basis for future interventions assess normal variations. Summary Background Data. Cervical movements are biomechanically neurophysiologically complex. Neck disorders trauma most often influence movements. With 3-dimensional recordings, it is possible make precise,...

Human postural dynamics was investigated in 12 normal subjects by means of a force platform recording body sway, induced bipolar transmastoid galvanic stimulation the vestibular nerve and labyrinth. The model adopted that an inverted segmented pendulum, control being assumed to be reflected stabilizing forces actuated feet as result complex muscular activity subject state feedback sway position. Time-series analysis demonstrates transfer function from stimulus sway-force response with...

Conclusion. The properties of a foam surface significantly affect body movement variance. Therefore, studies where different kinds have been used may not provide congruent results. Objectives. To investigate whether variance (32 subjects, mean age 22.5 years) in terms linear head, shoulder, hip and knee movements. Subjects repeated tests with eyes open closed, to also determine the effect vision on surfaces. methods. Body was captured three surfaces control solid over 2 min using Zebris™...

Deep brain stimulation (DBS) in the subthalamic nucleus (STN) significantly reduces symptoms of Parkinson's disease (PD) such as bradykinesia, tremor and rigidity. It also need for anti-PD medication, thereby potential side-effects L-Dopa. Although DBS STN is a highly effective therapeutic intervention PD, its mechanism effects on oculomotor eye movement control particularly smooth pursuit movements have to date rarely been investigated. Furthermore, previous reports provide conflicting...

<h3>Background:</h3> Unilateral vestibular deafferentation (uVD), as performed in schwannoma surgery, results a chronic deficit, though most of the insufficiency can be compensated by other sensory input. By training (prehabituation) before motor adaptation processes instigated actual lesion. The altered input could affected if ablation and surgery were separated time, pretreating patients who have remaining function with gentamicin. <h3>Objective:</h3> To determine whether presurgical would...

Objective: To develop and assess the efficacy of a multimodal balance-enhancing exercise program (BEEP) designed to be regularly self-administered by community-dwelling elderly. The aims promote sensory reweighting, facilitate motor control, improve gaze stabilization, stimulate continuous improvement being constantly challenging. Method: Forty participants aged 60 80 years performed 6 weeks BEEP training, on average for 16 min four times weekly, in randomized one-arm crossover design....

Useful clinical tests are lacking for the controversial entity "cervical vertigo". In earlier studies patients assumed to suffer from cervical vertigo or dizziness manifested disturbed postural control as compared healthy subjects, but were hard distinguish with other balance disorders. Using posturography in which stance was perturbed by a vibratory stimulus applied towards calf muscles, we studied 16 consecutive recent onset of neck pain and concomitant complaints dizziness, normal...
