步态分析的目的是量化一个人的行走
英文摘要
The purpose of gait analysis is to quantify a person's walking
pattern and the neuromuscular strategies the body uses to produce
the observed movement. A computerized video camera system measures
the movement pattern, and special platforms built into the floor
measure forces acting on the feet. From the measured movements and
forces, the mechanical work done by the body during walking can be
estimated Current techniques used to approximate work oversimplify
the model of the body and its movements and introduce errors into
the estimates.
Our research is investigating more complex models of the body to
learn how these models affect mechanical work estimates. One study
of 10 normal subjects that examined the work done at the ankle joint
during gait has been published. The study employed a more
sophisticated model of the ankle joint and included additional
terms, previously ignored, in the mechanical work calculations.
Data from another study, which examined the mechanical work done at
the knee joint, have been completed and presented. A third study
involving 15 subjects produced a dramatically improved model of the
foot. A study currently under way is investigating the effect of
dramatically different speeds on the mechanics of walking. It is
hypothesized that two modes of walking exist rather than a continuum
of a single walking strategy. A final study, which is near
completion, evaluate a new technique for determining the role each
major muscle group of the lower extremity plays in providing support
to and propulsion of the body during walking. The results of these
studies suggest that a complete and numerically consistent
mechanical characterization of human movement is feasible. The
application of these analytic techniques to the evaluation of human
motion will have implications for rehabilitation and surgical
treatment in patient populations.
