Laboratory studies have suggested that the preferred cadence of walking is approximately 120 steps/min, and the vertical acceleration of the head exhibits a dominant peak at this step frequency (2 Hz). These studies have been limited to short periods of walking along a predetermined path or on a treadmill, and whether such a highly tuned frequency of movement can be generalized to all forms of locomotion in a natural setting is unknown. The aim of this study was to determine whether humans…

Walking on an Oscillating Treadmill: Strategies of Stride-Time Adaptation

Although entrainment was not required for adaptation, it is reported compelling evidence that the frequency of the support-surface motion influenced the adapted strategies of 80% of the authors' participants.

Bipedal Steps in the Development of Rhythmic Behavior in Humans

The apparent absence of musical and rhythmic abilities in nonhuman primates, which display little bipedal locomotion, corroborates that bipedAL gait may be linked to the development of rhythmic ability in humans.

Self-generated sounds of locomotion and ventilation and the evolution of human rhythmic abilities

Four hypotheses are raised: human locomotion and ventilation can mask critical sounds in the environment, Predictable locomotion sounds may have improved the capacity of entrainment to external rhythms and to feel the beat in music, and Bipedal walking may have influenced the development ofEntrainment in humans and thereby the evolution of rhythmic abilities.

By counteracting gravity, triceps surae sets both kinematics and kinetics of gait

This study is the first to highlight that by merely counteracting gravity,triceps activity sets the kinematics and kinetics of gait and provides evidence that the surge in triceps activity during fast walking is due to the increased requirement of braking the fall of CoM in late stance in order to perform a smoother step‐to‐step transition.

The functional role of triceps during human locomotion

It is hypothesised that temporal modulation of TS activity determines global gait kinematics (cadence and step length) and kinetics and by controlling the distance between the two, the CNS modulates the disequilibrium torque that is responsible for propulsive force and thus the kinetics of gait.

Exercise, music, and the brain: Is there a central pattern generator?

A frequency of approximately 3 Hz seems to be dominant in different physiological systems and seems to been rated as pleasurable when choosing the appropriate music for exercising, in line with previous research showing that an adequate choice of music during exercise enhances performance output and mood.

Ecological Momentary Assessment of Head Motion: Toward Normative Data of Head Stabilization

It is suggested that head stabilization is tuned to the 2 Hz fundamental frequency of locomotion and that previously described measures of head stability could generalize to a real-world setting.

Standstill to the 'beat': differences in involuntary movement responses to simple and complex rhythms

It is found that on average participants moved more during the sound stimuli than in silence, which confirms the results from previous studies, and the stimulus with complex drum patterns elicited more movement when compared to the isochronous drum beats.

Dynamic primitives in the control of locomotion

This work proposes three primitives as a foundation for a comprehensive theoretical framework that can embrace a wide range of upper- and lower-limb behaviors and proposes mechanical impedances as a third class of dynamic primitives, necessary for interaction with the physical environment.

Head stabilization during various locomotor tasks in humans

The study emphasizes the importance of head stabilization as part of the postural control system and described as a basis for inertial guidance.

Locomotor head-trunk coordination strategies following space flight.

The coherence between pitch head and vertical trunk movements during gaze fixation of both FAR and NEAR targets was significantly reduced following space flight indicating decreased coordination between the head and trunk during postflight locomotion.

The Human Vestibulo‐Ocular Reflex during Linear Locomotion

Horizontal eye movements are compensatory for head yaw at all viewing distances and are likely generated by the aVOR, suggesting that the lVOR predominantly generates the eye movement response.

Head stabilization during various locomotor tasks in humans

In V subjects, head rotation was not found to be compensatory for head translation and the power spectrum analysis shows that head angular displacements in the sagittal plane contain mainly low frequencies (about 0.3–0.8 Hz).

Effects of walking velocity on vertical head and body movements during locomotion

It is suggested that two mechanisms are utilized to maintain a stable head fixation distance over the optimal range of walking velocities, and that compensatory head pitch movements may be produced predominantly by the angular vestibulocollic reflex (aVCR) at low walking speeds and by the linear vestibULocolli reflex (lV CR) at the higher speeds.

Space-time behavior of single and bimanual rhythmical movements: data and limit cycle model.

The abstract, dynamical model offers a unified treatment of a number of fundamental aspects of movement coordination and control in terms of low-dimensional (nonlinear) dissipative dynamics, with linear stiffness as the only control parameter.

Effect of viewing distance on the generation of vertical eye movements during locomotion

The results of the head-fixed target experiment suggest that phase modification of the aVOR during visual suppression could play a role in generating eye movements consistent with the goal of maintaining gaze on targets closer than the HFD, which would augment the lVOR response.

Instability of gaze during locomotion in patients with deficient vestibular function

Testing of patients with vestibular symptoms should include stimuli corresponding to the rotational head perturbations that occur during locomotion; such head rotations have nonpredictable characteristics and a frequency range of 0.5 to 5.0 Hz.

During ambulatory activities, normal and magnified vision were associated with VV OR gain enhancement in pitch and yaw that was statistically significant, but substantially less than was telescope magnification and markedly lower than was the corresponding VVOR gain measured during active head rotation.

Moving rhythms

The existence of central pattern-generating circuits was first demonstrated by experiments showing that rhythmic movements are still produced after all the sensory feedback from limbs is removed, and was defined as circuits that can produce rhythmic motor patterns in the absence of phasic drive.
