Autonomic dysreflexia is a complication of spinal cord injuries. “It is a massive, uncompensated cardiovascular reaction mediated by the sympathetic nervous system” (Lewis, 2014, p.1784). There are many factors that need to be explored in relation to the complication of autonomic dysreflexia in spinal cord injuries. These factors include etiology, pathophysiology, clinical manifestations, diagnostics, and collaborative care.
Lewis (2014) states “ spinal cord injuries are generally the direct result of trauma that causes cord compression, ischemia, edema, and possible cord transection”(p.1172). The level and degree of injury have a direct relation to the severity of symptoms, with the higher the injury, the more loss of function you have because of the close proximity to the brain stem, medulla, and cervical cord (Lewis, 2014). There are five major mechanisms of injury including hyperextension, flexion, flexion-rotation, extension-rotation, and compression (Lewis, 2014). Complete injury means there is no sensory or motor function below the level of injury. Incomplete injury is a mixed loss of motor and sensory function below the level of injury. The degree varies between sensory and motor loss due to the level of injury (Lewis, 2014). There are three levels of injury, those being cervical, thoracic, and lumbar. Lumbar and cervical injuries are the most common due to movement and increased flexibility (Lewis, 2014). Depending on the degree of injury you may become a paraplegic or a tetraplegia. Paraplegia is a loss of sensation in the trunk and lower limbs due to the thoracic cord in the lumbar spine being damaged (Lewis, 2014). Tetraplegia is paralysis in all four extremities due to the cervical cord being

    Spinal muscular atrophy [SMA] is a disorder in which, you have a loss of motor neurons. Your muscle symmetry is often off. In addition, there is muscle weakness in your spinal cord. This occurs in a hard time sitting up and holding your head up on your own. It is just like when you are a newborn and you need a pillow to sit on the couch. A few major causes of SMA are loss of motor neuron cells or nerve cell. This mutation leads to a deficiency of motor neuron cells or nerve cells. The disorder SMA is tied to the gene "SMN1" and tied to chromosome 5. A few symptoms of this disorder are- difficulty breathing lack of oxygen, difficulty eating, floppy posture, small amount of movement, and all these symptoms will gradually get worse over time. All these symptoms are at about a mild level in the beginning.…

    R.B. is a 36 year old male who dove off the back of a boat into shallow water and sustained a cervical burst fracture of the 4-5 vertebrae. He had congenital narrowing of the spinal canal which made his injury more devastating because as his spinal cord swelled after the accident it ascended up the spinal cord leaving him unable to feel or move below the level of C2 and unable to breathe on his own. Once the R.B. was stable enough he was transferred to a rehabilitation hospital that specialized in spinal cord injuries.…

    Spinal cord injury (SCI) is a traumatic and devastating event in any person’s life (Chen, 2013). Spinal cord injury might be partial or total, but whichever type can cause impairment of physical mobility leaving those affected with challenges of coping with rehabilitation. However, current treatment continues to focus in the provision of care in the acute stage and the prevention and (Chen, 2013) treatment of complications (Chen, 2013). SCI continues to impact the lives of those affected and their families socially, physically, mentally, and spiritually. Independence to the greatest ability of the patient is a long-term goal. By providing a multi-disciplinary team to treat a patient, it gives additional professional support to allow a more rounded, stronger, and more positive recovery. Although many scientists are studying nerve regeneration and conducting stem cell research (Chen, 2013) for the treatment of SCI but the cure is still a long way off (Chen, 2013). However, self-perception, age, self-efficacy are factors influencing individuals with SCI to successfully moving forward without withdrawing from the society. Patients who effectively learn to…

    Speech-Language Pathologists (SLPs) working in the medical setting are typically members of rehabilitation teams, who work with individuals who have suffered from an illness, disease, or injury that may result in neurological deficits affecting speech, language, and/or cognition. Specifically, when working with the adult population, SLPs frequently assess and treat individuals diagnosed with a motor speech disorder called dysarthria. There are many types of dysarthria that can be characterized by deficits in strength, speed, range of movement, steadiness, tone, and overall accuracy (Duffy, 2013). Therefore, it is important that SLPs have an understanding of the neurological system, prominent characteristics, and know a variety of therapy…
