OBJECTIVE We investigated trunk control, protective arm movements, and electromyographic responses to multidirectional support-surface rotations in patients with Parkinson's disease (PD), aiming to better understand the pathophysiology underlying postural instability in PD, on and off antiparkinson medication. METHODS Ten patients with PD were compared with 11 age matched healthy controls. Se...

The central role of trunk control in the gross motor function of children with cerebral palsy: a retrospective cross-sectional study. AIM: Improvement of gross motor function and mobility are primary goals of physical therapy in children with cerebral palsy (CP). The purpose of this study was to investigate the relationship between segmental control of the trunk and the corresponding gross moto...

BACKGROUND The correction of trunk deformity is crucial in scoliosis surgery, especially for the patient's self-image. However, direct visualization of external scoliotic trunk deformity during surgical correction is difficult due to the covering draping sheets. METHODS An optoelectronic camera system with 10 passive markers is used to track the trunk geometry of 5 scoliotic patients during c...

BACKGROUND Individuals with cervical spinal cord injury usually sustain impairments to the trunk and upper and lower limbs, resulting in compromised sitting balance. The objectives of this study were to: 1) compare postural control of individuals with cervical spinal cord injury and able-bodied individuals; and 2) investigate the effects of foot support and trunk fluctuations on postural contro...

Introduction Though adolescent idiopathic scoliosis (AIS) is characterized by a lateral deviation of the spine with resulting geometric changes in the trunk and rib cage standing imbalance was reported. The type and location of the spinal deformity was shown to perturb balance control while the interaction between standing posture and balance in AIS suggest a dysfunction in the postural regulat...

Aim: The purpose of our study was to examine the relation between upper extremity function and trunk control, balance functional mobility in Individuals with Stroke.
 Material Method: This included a total 39 stroke patients (age 63.87± 9.03 years, post 19.18±16.38 month). Upper functions were evaluated sub-scale STREAM Scale, level, control Trunk Impairment Scale (TIS), Berg Balance (BBS)...

The purpose of this study was to evaluate the effects of core strengthening combined with pelvic proprioceptive neuromuscular facilitation (PNF) on trunk impairment, balance, gait, and functional ability of chronic stroke patients. Twenty-three participants with chronic stroke were recruited and randomly allocated to one of the two groups: core strengthening combined with pelvic PNF (group 1, n...

[Purpose] The trunk muscles frequently become weak after stroke, thus impacting overall activities of daily living. However, activities of daily living items closely related with trunk strength remain unclear. This study aimed to clarify the influence of trunk muscle weakness on activities of daily living items. [Subjects] The subjects were 24 stroke patients who fulfilled the following inclusi...

The purpose of this study was to examine the muscular activity and kinematics of the trunk during unstable sitting and to determine differences between healthy and low back pain (LBP) participants. The participant sat on a custommade chair that was allowed to swing freely in the sagittal plane. They were asked to regain balance after the chair was tilted forward 20o and released. The movements ...
