  • Patent number: 5318058
    Abstract: A novel improvement in a crutch device allowing for the rotational movement of the arms and elbows of the user while supporting his/her weight on a pair of these crutches, by displacing the vertical support means, between the under-arm rest and the hand rest, rearward a sufficient distance. This improvement, combined with an all terrain crutch pad and easy adjustable crutch length allows an individual with severe restriction in mobility from the waist down to play active sports, such as golf, and engage in employment requiring the free movement of hands and arms while maintaining mobility of the total person.
