Introduction[edit | edit source]
A fundamental body movement is required to ascend and descend stairs. It is important for everyday activities such as shopping, taking public transportation, or simply going about a multistory home or building. The variation between the two modes of locomotion(level-ground locomotion and stair locomotion) may be significant for a patient population.If a patient has adequate muscle strength and joint ROM for level-ground walking, it does not ensure that the patient will be able to walk up and down stairs.
Biomechanics[edit | edit source]
Locomotion in the stair gait involves both swing and stance phases in which forward progression of the body is brought about by alternating movements of the lower extremities. The lower extremities must balance and carry along HAT(Head, arms and trunk), similar to level ground gait. There is a relationship between the BMI of the subject and also the respective loads at each of the joints.[1]The knee extensor moment in both stair ascent and descent was nearly three times greater than that of level ground walking. The ankle moments are almost similar in both gaits. The knee has generative role in stair ascent( absorptive in level walking). Powers are mostly generative in stair ascent and absorptive in descent for all joints.
