Modified prone push up in high  paraplegics – who have weakness in trunk and unable to do push up for upper limb strengthening. in that case we can put a big bolster under the chest and  raise and support the upper trunk on the bolster that will help him balance and control the upper trunk and could put more efforts in prone push ups and help in strengthening of upper limb.

Quadriplegics with weak triceps also have difficulty in prone push up also can be benefited by this technique.
