Associations of Postural Activities and Knowledge for Voice with Breathing Issues and Voice-Physical-Disorders Among Lyric Singers.

Objectives/hypothesis: The purpose of this research was to study the associations of postural activities and knowledge of the voice of opera singers, recognized in the literature for the specificity of their posture. Additionally, the link between vocal pathologies and body pains on one hand, and posture control on the other hand was investigated.

Methods: A questionnaire including 90 questions was distributed to singers in France and overseas during 6 months.

Rehabilitation of Postural Control and Gait in Children with Cerebral Palsy: the Beneficial Effects of Trunk-Focused Postural Activities.

Purpose: In children with cerebral palsy (CP), with impaired trunk control and toe-walking, trunk-focused rehabilitation (TFR) based on postural activities was hypothesized to improve trunk postural control, early trunk deceleration, and ankle dorsiflexion braking during walking. Methods: Seventeen children with CP (5-12 years) walking autonomously were randomly assigned to TFR and then usual rehabilitation (TFR-UR) or vice versa (UR-TFR).

Results: Only after TFR was significant improvements in (i) the Trunk Control Measurement Scale score, postural sway on an unstable sitting device and standing, and (ii) early sternal and sacral decelerations and coupled negative ankle power due to plantar flexors.

Understanding and Managing Trauma-Induced Vestibular Deficits.

Objectives: Traumatic brain injury occurs frequently worldwide. Half of traumatic brain injuries are related to falls or motor vehicle accidents. The term "concussion" is often used to describe a minor form of traumatic brain injury.

Impaired postural control of axial segments in children with cerebral palsy.

Background: Sensorimotor control of axial segments, which develops during childhood and is not mature until adolescence, is essential for the development of balance control during motor activities. Children with cerebral palsy (CP) have deficits in postural control when standing or walking, including less stabilization of the head and trunk which could affect postural control.

Research Question: Is dynamic stabilization of axial segments during an unstable sitting task deficient in children with CP compared to typically developing children? Is this deficit correlated with the deficit of postural control during standing?

Method: Seventeen children with CP (GMFCS I-II) and 17 typically-developing children from 6 to 12 years old were rated on the Trunk Control Measurement Scale (TCMS).

Toe walking in children with cerebral palsy: a possible functional role for the plantar flexors.

Equinus and toe walking are common locomotor disorders in children with cerebral palsy (CP) walking barefoot or with normal shoes. We hypothesized that, regardless of the type of footwear, the plantar flexors do not cause early equinus upon initial foot contact but decelerate ankle dorsiflexion during weight acceptance (WA). This latter action promoted by early flat-foot contact is hypothesized to be functional.
