Question

Tom is a 34 y/o IT analyst who was recently diagnosed with a tumor in the posterior aspect of his spinal cord at C6 that has resulted in a spinal cord injury with changes in sensation. Tom lives in a private home with his wife and two-year-old daughter. Questions: • What ascending spinal tract(s) have been affected? • What types of sensation have been affected and what types remained intact? (i.e. temperature, pain, proprioception, etc.) • Where on Tom’s body will the sensory deficits be present? Use specific dermatomes. • What are the implications of this sensory loss on Tom’s function? • Given the sensory changes you discussed above, what areas of occupation might be affected? What are some associated functional activities would be difficult for Tom to perform? Why?

Answer 1

Ans:- a) DCML dorsal columne medial laminiscus which include two track gracelis track which carry sensory fibers from leg and cunieate track which carry sensory supply from upper limb and thorax... DCML is mainly response for carrying

B) CRUDE TOUCH ,PRESSURE, PROPRIOCEPTION , vibration , are lost all other sensation like motor sensation,

And sensation carry by Lateral spinothalamic like PAIN AND TEMPERATURE , and sensation carry by VENTRAL SPINOTHALAMIC TRACK LIKE FINE TOUCH is intact

C) as C6 segment of spinal cord is injured so area of hand which include thumb and lateral radial part of forearm sensation is effected.

D) implications:numbnes of thumb which make it prone to unnoticed injury and wounds...

E) as in lesion of spinal cord at the level C6 ALL THE FIBERS AFTER C6 will loss there sensory ability so he will loss sensation in some part of hand and all sensory supply from lower limb. So he might find difficultly in typing ...
