Final answer:
Physical motor impairment can restrict oral communication by affecting the function and endurance of the upper extremities. Fractures and neurological impairments such as aphasias, which disrupt language and speech, are common culprits. Global neurological events that cause a combination of sensorimotor, memory, emotional, and language deficits exemplify a serious level of damage.
Step-by-step explanation:
Physical motor impairment may limit the choice of oral communication by impacting upper extremity function and endurance. Disorders such as fractures of upper limb bones can greatly decrease functional ability due to the necessity of hands and arms in many daily tasks. Fractures can occur from a hard fall onto an outstretched hand, leading to fractures of the humerus, radius, or scaphoid bones, and these are particularly prevalent in the elderly due to conditions like osteoporosis.Moreover, neurological impairments affecting language and speech functions, known as aphasias, result from damage to areas like Broca's or Wernicke's in the brain. Such damage may lead to conditions such as receptive aphasia, where there's a loss of the ability to understand language, or expressive aphasia, representing a loss in the ability to produce language. Right-side brain damage can also impede nonverbal aspects of speech like facial expressions or body language, often leading to 'flat affect' in speech.Lastly, in the context of the neurological exam, it's crucial to determine the root cause of the issues, whether they are acute, such as a stroke, or chronic, like blunt force trauma. An injury that causes sensorimotor deficits, along with memory, emotional, and language issues, suggests a global event which is affecting multiple aspects of the patient's neurological function.
