A study of normal locomotion requires an understanding of both the movements and the force actions involved. This is equally true in appreciating the problems of pathological gait.The gait cycle is described in terms of the significant events which occur during both the stance and swing phases.The basic principles underlying the analysis of force actions in walking are briefly described. A simple example of force actions in the elbow joint is considered and the analysis extrapolated to provide a general statement regarding locomotion. This relates to the muscle actions required to resist turning actions at joints due to the force effects in walking and the corresponding forces in the joints themselves.The conventional display of information relating to joint actions is considered and compared with the actual situation. “Stick diagrams” of motion in the sagittal plane are used to identify and discuss the actions at the joints of the leg in walking. Comparisons are made between this and pathological gait—in...

Walking aids for stroke patients.

The existing locomotion evaluation techniques are based either on bioenergetic measurements or on biomechanical principles and procedures. While the former basis has been preferred by a few, published literature in this field has contained more information on the latter. No significant work combining both the approaches in a single measurement system is known so far. This paper reports an investigation where an attempt was made to combine both the techniques in relation to a mixed handicapped population composed of 10 test subjects as well as a matching control group. It has been found from the present investigation that the combined application of the above two types of measurements might lead to more useful information about the performance level of the subjects in locomotion. Further, the statistical analysis of the experimental data revealed the existance of a linear correlationship among the parameters used for such performance evaluation. Finally, the study findings have been discussed to indicate how the biomechanical measurements alone can throw sufficient light on the subject's locomotor status.
