What occurs as a result of an injury at the level between C6 and C7?

• A. Paralysis of legs and trunk
• B. Loss of wrist movement
• C. Normal movement of the shoulders and elbows
• D. Complete loss of all arm functions

Answer: (C)

An injury at the level between C6 and C7 primarily affects the spinal cord segments that correspond to those cervical levels. At this injury site, a person may experience impairment depending on the specific nature of the injury, but generally, the key movements that would still be functional include the ability to move the shoulders and elbows. The C6 nerve root controls muscles that allow for elbow flexion and some wrist extension. The C7 nerve root contributes to the control of elbow extension and some hand functions. Therefore, an individual with an injury at this level would typically retain the ability to move their shoulders and may also have functioning elbow movements to some extent. This retained motion is an important compensatory mechanism, allowing for some level of arm function and assisting with daily activities. Maintaining shoulder and elbow movement is crucial, as it can greatly affect the individual’s ability to perform tasks and improve independence despite the injury. Understanding the functional outcomes of cervical spinal injuries helps in the rehabilitation and adaptation process, emphasizing the importance of preserving as much function as possible.
