| Abstract: | Chronic bed rest (BR) serves as a model for studying the effects of prolongedimmobility on physiological and neuromotor functions, particularly postural control. ProlongedBR leads to significant deconditioning of postural balance control, characterized by increasedsway path lengths, sway velocity and fall risk, independent of muscle strength. These changes arelinked to neural adaptations at spinal and supraspinal levels, including structural and functionalbrain changes, such as alterations in grey and white matter, increased cerebellar activation,reduced spinal excitability and increased latencies within reflex circuitries. Additionally, BRdisrupts sensory integration from proprioceptive, visual and vestibular systems, impairing post-ural stability. Visual reliance remains stable during BR, though decreased visual acuity andcontrast sensitivity are noted. Moreover, BR-induced shifts in cerebrospinal fluid contribute toaltered brain activity, impacting sensorimotor function. Vestibular system adaptations, includingchanges in vestibulospinal reflexes, further exacerbate balance impairments. Understanding thesemechanisms is crucial for developing interventions to mitigate the adverse effects of BR onpostural control and prevent prolonged recovery times or increased risk of injury. This reviewhighlights the need for further research into the neural underpinnings of BR-induced posturalinstability, with a focus on sensory integration and neuroplasticity |
