BACKGROUND Walking instability and a higher risk of falls are common in patients with peripheral neuropathy. However, it remains uncertain as to whether alterations in neuropathic gait are directly related to deficient sensory locomotion control or due to a slowing of walking speed. By means of a multi-speed gait assessment we determined factors related to(More)
OBJECTIVE This study investigated the influence of impaired cerebellar locomotion function on the magnitude and structure of stride-to-stride fluctuations in the walking pattern. On the basis of studies reporting a dependency of variability magnitude and structure on the walking speed, we hypothesized that patients with cerebellar ataxia (CA) would show(More)
This review shows that persons with visual height intolerance or acrophobia exhibit typical restrictions of visual exploration and imbalance during stance and locomotion when exposed to heights. Eye and head movements are reduced, and gaze freezes to the horizon. Eye movements tend to be horizontal saccades during stance and vertical saccades during(More)
BACKGROUND Subjective postural imbalance is a key symptom in the somatoform phobic postural vertigo (PPV). It has been assumed that more attentional control of body posture and / or co-contraction of leg muscles during standing is used to minimize the physiological body sway in PPV. Here we analyze nonlinear variability of body sway in patients with PPV in(More)
Falls are common in patients with cerebellar ataxia (CA). Identification of gait variables associated with a higher risk of falls allows us to detect fallers and initiate protective procedures early. Gait variability, which is increased in CA patients, is a good predictor of falls in elderly subjects and patients with neurodegenerative diseases. The(More)
OBJECTIVE Automated pattern recognition systems have been used for accurate identification of neurological conditions as well as the evaluation of the treatment outcomes. This study aims to determine the accuracy of diagnoses of (oto-)neurological gait disorders using different types of automated pattern recognition techniques. METHODS Clinically(More)
OBJECTIVE To examine the effects of imperceptible levels of white noise galvanic vestibular stimulation (nGVS) on dynamic walking stability in patients with bilateral vestibulopathy (BVP). METHODS Walking performance of 13 patients with confirmed BVP (mean age 50.1 ± 5.5 years) at slow, preferred, and fast speeds was examined during walking with(More)
BACKGROUND White noise galvanic vestibular stimulation (GVS) is thought to enhance the sensitivity of vestibular organs. OBJECTIVE To examine the effects of noise-enhanced vestibular input on the walking performance in healthy subjects walking with eyes closed. METHODS Walking performance of 17 healthy subjects (mean age 28.8 ± 1.7 years) at slow,(More)
