Objectives: To determine if hippotherapy (therapy using a horse) improves head/trunk stability and upper extremity (UE) reaching/targeting in children with spastic diplegia cerebral palsy (SDCP).
Design: Pre-postoperative follow-up with a 12-week intervention and 12-week washout period after intervention.
Setting: A human performance laboratory with 6 camera video motion capture systems for testing.
Participants: Eleven children (age 5-13y, average 8y) with SDCP, 8 children (age 5-13y, average 8y) without disabilities.
Intervention: Hippotherapy intervention performed at 3 therapeutic horseback riding centers.
Main Outcome Measures: Video motion capture using surface markers collecting data at 60 Hz, a mechanical barrel to challenge trunk and head stability, and functional reach/targeting test on static surface.
Results: Significant changes with large effect sizes in head/trunk stability and reaching/targeting, elapsed time, and efficiency (reach/path ratio) after 12 weeks of hippotherapy intervention. Changes were retained after a 12-week washout period.
Conclusions: Hippotherapy improves trunk/head stability and UE reaching/targeting. These skills form the foundation for many functional tasks. Changes are maintained after the intervention ceases providing a skill foundation for functional tasks that may also enhance occupational performance and participation.

Trunk, head, and step characteristics during normal and narrow-based walking under deteriorated sensory conditions.
J Mot Behav

The ability to maintain stability in the frontal plane (medialateral direction) while walking is commonly included as a component of motor performance assessment. Postural control in the frontal plane may deteriorate faster and earlier with increasing age, compared to that in the sagittal plane (anteroposterior direction). Fifteen young (20-30 years old) and 15 older (>65 years old) healthy participants were recruited to investigate age-related differences in postural control during the normal and narrow-based walking when performed under suboptimal vestibular and lower limb somatosensory conditions achieved by galvanic stimulation and compliant surfaces, respectively.

This study examined the relationship between head and trunk sway during quiet stance and compared this relationship with that of the pelvis to the trunk. Sixteen younger and 14 elderly subjects participated, performing four different sensory tasks: standing quietly on a firm or foam support surface, with eyes open or closed. Roll and pitch angular velocities were recorded with six body-worn gyroscopes; a set of two mounted at the upper trunk, an identical set at the hips, and another set on a head band.

Vestibulopathy and age effects on head stability during chair rise.
Acta Otolaryngol

Department of Orthopaedics, Massachusetts General Hospital, Boston 02114, USA.
It is unknown how vestibular dysfunction and age differentially affect balance control during functional activities. The objective of this study was to gain insight into the effects of age and vestibulopathy on head control when rising from a chair. Head relative to trunk (head-on-trunk) sagittal plane angular and linear control strategies were studied in patients with bilateral vestibular hypofunction (BVH) and in healthy subjects aged 30-80 years.

The activity of 68 neurons, mainly Purkinje cells, was recorded from the cerebellar anterior vermis of decerebrate cats during wobble of the whole animal (at 0.156 Hz, 5 degrees), a mixture of tilt and rotation, leading to stimulation of labyrinth receptors. Most of the neurons (65/68) were affected by both clockwise and counterclockwise rotations.
