Abstract
Temporal gait variability is a critical parameter in patients with balance problems. Increased magnitude of temporal gait variability corresponds to a higher risk of falls. The purpose of this study was to investigate the influence of walking speed on temporal stride-to-stride variability in patients with cerebellar and vestibular deficits. A GAITRite system was used to analyze the gait of 40 patients with cerebellar ataxia, 22 patients with bilateral vestibular failure, and 51 healthy subjects over the entire range of the individual's speed capacity. The coefficient of variability of stride time was calculated for each walk. Temporal gait variability was increased in cerebellar patients and vestibular patients. The magnitude of this variability depended on walking speed in a disease-specific manner. In patients with cerebellar ataxia, variability was increased during slow (8.4 ± 5.3%, P < .01) and fast (7.9 ± 6.4%, P < .01) walking speed but was normal during preferred walking speed. This resulted in a speed-related U-shaped function of stride-time variability. Patients with vestibular failure had increased variability during slow walking (9.9 ± 4.3%, P < .01). During walking with medium and fast walking speed, stride time variability was normal. Minimal temporal gait variability appears to be attractive for the locomotor system in cerebellar patients because these patients preferred to walk at a velocity associated with minimal stride-time variability. In contrast to previous studies, vestibular patients accelerate rather than decelerate gait to achieve dynamic stability. This may be explained by reduced sensory integration during fast locomotion.

In patients with cerebellar ataxia, variability was increased during slow (8.4 ± 5.3%, P < .01) and fast (7.9 ± 6.4%, P < .01) walking speed but was normal during preferred walking speed. This resulted in a speed-related U-shaped function of stride-time variability. Patients with vestibular failure had increased variability during slow walking (9.9 ± 4.3%, P < .01). During walking with medium and fast walking speed, stride time variability was normal. Minimal temporal gait variability appears to be attractive for the locomotor system in cerebellar patients because these patients preferred to walk at a velocity associated with minimal stride-time variability. In contrast to previous studies, vestibular patients accelerate rather than decelerate gait to achieve dynamic stability. This may be explained by reduced sensory integration during fast locomotion.</s0></fC01><fC02 i1="01" i2="X"><s0>002B17</s0></fC02><fC02 i1="02" i2="X"><s0>002B17G</s0></fC02><fC03 i1="01" i2="X" l="FRE"><s0>Pathologie du système nerveux</s0><s5>01</s5></fC03><fC03 i1="01" i2="X" l="ENG"><s0>Nervous system diseases</s0><s5>01</s5></fC03><fC03 i1="01" i2="X" l="SPA"><s0>Sistema nervioso patología</s0><s5>01</s5></fC03><fC03 i1="02" i2="X" l="FRE"><s0>Locomotion</s0><s5>09</s5></fC03><fC03 i1="02" i2="X" l="ENG"><s0>Locomotion</s0><s5>09</s5></fC03><fC03 i1="02" i2="X" l="SPA"><s0>Locomoción</s0><s5>09</s5></fC03><fC03 i1="03" i2="X" l="FRE"><s0>Vitesse déplacement</s0><s5>10</s5></fC03><fC03 i1="03" i2="X" l="ENG"><s0>Speed</s0><s5>10</s5></fC03><fC03 i1="03" i2="X" l="SPA"><s0>Velocidad desplazamiento</s0><s5>10</s5></fC03><fC03 i1="04" i2="X" l="FRE"><s0>Variabilité</s0><s5>11</s5></fC03><fC03 i1="04" i2="X" l="ENG"><s0>Variability</s0><s5>11</s5></fC03><fC03 i1="04" i2="X" l="SPA"><s0>Variabilidad</s0><s5>11</s5></fC03><fC03 i1="05" i2="X" l="FRE"><s0>Ataxie cérébelleuse</s0><s2>NM</s2><s5>12</s5></fC03><fC03 i1="05" i2="X" l="ENG"><s0>Cerebellar ataxia</s0><s2>NM</s2><s5>12</s5></fC03><fC03 i1="05" i2="X" l="SPA"><s0>Ataxia cerebelosa</s0><s2>NM</s2><s5>12</s5></fC03><fN21><s1>079</s1></fN21><fN44 i1="01"><s1>OTO</s1></fN44><fN82><s1>OTO</s1></fN82></pA></standard></inist><affiliations><list><country><li>Allemagne</li></country><region><li>Bavière</li><li>District de Haute-Bavière</li></region><settlement><li>Munich</li></settlement><orgName><li>Université Louis-et-Maximilien de Munich</li></orgName></list><tree><country name="Allemagne"><region name="Bavière"><name sortKey="Schniepp, Roman" sort="Schniepp, Roman" uniqKey="Schniepp R" first="Roman" last="Schniepp">Roman Schniepp</name></region><name sortKey="Brandt, Thomas" sort="Brandt, Thomas" uniqKey="Brandt T" first="Thomas" last="Brandt">Thomas Brandt</name><name sortKey="Brandt, Thomas" sort="Brandt, Thomas" uniqKey="Brandt T" first="Thomas" last="Brandt">Thomas Brandt</name><name sortKey="Dimitriadis, Konstantin" sort="Dimitriadis, Konstantin" uniqKey="Dimitriadis K" first="Konstantin" last="Dimitriadis">Konstantin Dimitriadis</name><name sortKey="Jahn, Klaus" sort="Jahn, Klaus" uniqKey="Jahn K" first="Klaus" last="Jahn">Klaus Jahn</name><name sortKey="Jahn, Klaus" sort="Jahn, Klaus" uniqKey="Jahn K" first="Klaus" last="Jahn">Klaus Jahn</name><name sortKey="Kamenova, Maria" sort="Kamenova, Maria" uniqKey="Kamenova M" first="Maria" last="Kamenova">Maria Kamenova</name><name sortKey="Klopstock, Thomas" sort="Klopstock, Thomas" uniqKey="Klopstock T" first="Thomas" last="Klopstock">Thomas Klopstock</name><name sortKey="Neuhaeusser, Maximilian" sort="Neuhaeusser, Maximilian" uniqKey="Neuhaeusser M" first="Maximilian" last="Neuhaeusser">Maximilian Neuhaeusser</name><name sortKey="Schniepp, Roman" sort="Schniepp, Roman" uniqKey="Schniepp R" first="Roman" last="Schniepp">Roman Schniepp</name><name sortKey="Strupp, M" sort="Strupp, M" uniqKey="Strupp M" first="M." last="Strupp">M.
