摘要：
The need of ergonomically modified crutches (i) To enable orthopedically limb challenged people to walk over uneven ground. (ii) To provide better support and grip in polished and water surfaces (iii) To enable orthopedically limb challenged people to use the crutches with minimum training. The bottom design of crutch has been modified for the reason which enables them to walk over the piped cattle barriers. Cattle barriers are a common phenomenon in India. Cattle barriers are installed in most of the government buildings to avoid the entry of cattle. The problem is that cattle barriers not only prevent cattle but also orthopedically challenged people who use axial crutches from passing through this hurdle. This creates a lot of troubles to the people who use crutches. They often face the danger of stumbling and falling down at the entrance. The resultant injury is not only physical but also psychological. The only alternative before them is to secure the help of a able bodied person. The present design prevents this problem and enables the orthopedically challenged people to walk over cattle barriers. The design of the improvised ergonomically modified crutch is as follows: instead of the normal rod like bottom part of the crutch, the bottom of ergonomically modified crutch is modified as curved inverted "V" shape for holding the pipes and other rugged surfaces. It is completely made of aluminium as the same material for all crutches which is weightless and affordable by all people. The "V" is not by lines and made of curves for enabling to hold pipes of any range. The grove is cut on the upper part of the "V" plate and the stem is seated in it which provides better angle twist for the ease of the user and better support while walking. The circular bush is changed to rectangular bush as it increases the contact surface with the ground and avoids slipping. And the swinging motion is essential in the crutch for better ease in movement and it is provided in the improv
