Identification of static and dynamic postural instability following traumatic brain injury

摘要: Abstract Objective: Quantitative evaluation of static and dynamic aspects postural instability as a long-term consequence traumatic brain injury (TBI). Design: Experimental two-group design. Setting: Outpatient rehabilitation department. Patients Other Participants: From consecutive sample TBI patients at least 6 months after trauma, 20 subjects were selected who complained reduced gross motor skills but showed no sensorimotor impairments in standard neurological examination (11 men, 9 women; mean age, 36.2 ± 10.7 years). Thirteen had sustained mild, 2 moderate, 5 severe TBI. Twenty healthy controls matched for age gender. Intervention: None. Main Outcome Measures: A dual-plate force platform recorded the amplitude velocity center-of-pressure fluctuations anteroposterior (AP) lateral (LAT) sway directions during quiet standing. Also, speed fluency weight shifting using visual feedback was registered. Both balance tasks combined with an arithmetic task, whereas standing also tested deprivation. Results: Compared to controls, increase over 50% AP LAT sway, weight-shifting 20% lower. Dual-task interference never significant. Visual deprivation most detrimental particularly control. Conclusion: overall reduction both control posture can be present TBI, even without clear deficits. Force-plate recordings identify such (latent) problems. appears simple, sensitive test related sensory integration
