Innovative design of sickbed for decubitus ulcer free : Force analysis of muscles and joints

A strategy was proposed to the rule for paralyzed patients. One goal of the design is to reduce or avoid the occurrence of decubitus ulcer. The other goal is to reduce the decline of muscle strength of patient.
The contents of the study include collection and system analysis. The issue is know how the burdens of muscles are affected by the locations and postures that sickbed supporting the body. To attack this issue, a simplified body model, which is consisted of 11 rigid bodies, is proposed. An analysis method, which adopts the optimization approach, is suggested to calculate the ¡§ relaxed burdens of muscles ¡¨. Apply the mathematical model of the optimization to acquire an analysis method of the relaxed burdens of muscles, modeling the concern of the support loading and burdens of muscles.
According to the analysis answer of the mathematical model verified that a patient lay on the bed by the horizontal postures and variation postures, the best support locations resulted in the relaxed burdens of muscles and strengthen muscles. So, the rule of the logical thinking to reduce or avoid the occurrence of decubitus ulcer and the decline of muscle strength.
