Abstract
An apparatus for the practice of ambulation comprises a suspension member for suspending a patient, a weight sensor for detecting a weight applied to the suspension member, an air cylinder or motor for producing a predetermined suspension force to be conveyed to the suspension member, a horizontal arm for supporting the suspension member, and a rotation axle for rotating the horizontal arm and the suspension member so that the patient who is suspended by the suspension member can be trained in walking in accordance with a predetermined suspension force which is proportional to a weight detected by the weight sensor.
Claims21
An apparatus for the practice of ambulation, comprising:
- means for suspending a patient by a predetermined suspension force;
- means for producing said predetermined suspension force;
- means for supporting said suspending means and conveying said predetermined suspension force thereto;
- means for detecting a weight applied to said suspending means to produce a corresponding weight signal;
- and
- means for controlling said suspension force producing means to produce thereby said predetermined suspension force related to said detected weight by receiving said weight signal from said detecting means, wherein said controlling means cooperates with said detecting means to limit an increase of said predetermined suspension force when said detected weight is increased by more than a predetermined rate.
