What limitation is observed in individuals with C7 spinal cord injury?

Individuals with a C7 spinal cord injury typically retain the ability to use their shoulders and have some degree of upper limb function. Specifically, they often possess the capability to flex their elbows and perform wrist movements. The most significant limitation observed in these individuals is the lack of fine motor control and grasping ability, which is crucial for tasks involving manipulation and holding objects.

Although they can move their shoulders and flex their elbows, the injury impacts their ability to perform more intricate tasks that require precision. This affects their independence and ability to execute daily living activities effectively. The condition results in weak grip strength and difficulty in grasping objects, which is why this limitation is emphasized in the context of a C7 spinal cord injury.
