DESCRIPTION:
BRIEF SUMMARY
Industrial Field
The invention relates to medical instruments and equipment and has specific reference to walking-simulating apparatus for persons with restricted mobility.
BACKGROUND OF THE INVENTION
It is well known that in cases of restricted (impaired) mobility the bearing surfaces of the soles of the feet are not exposed to the effect of normal walking when these surfaces, the Achilles tendon and other structures taking part in the movement are stimulated at regular intervals concurrently with the rhythm of walking.
Lack of stimulant for mechanoreceptors leads to problems in static and kinetic control.
There is known a method of keeping or simulating orthostatic balance in cases of restricted (impaired) locomotion according whereto the body of a man is linked to a supporting means by a resilient link and exposed to inertial shock loads of short duration applied along the body's longitudinal axis so as to overcome the elastic forces of the link (cf. USSR Inventor's Certificate No. 256164, IPC A 61 H 1/00, Bulletin "Discoveries, Inventions, Industrial Designs and Trade Marks" No. 25, 1976; Inventors: V. V. Bazhanov, A. V. Eremin, V. I. Stepanov, L. P. Salmanov and V. A. Titler).
Also known is a walking-simulating apparatus for persons suffering from restricted mobility of various degree consisting of two platforms which give support to the feet and are provided with vibrators located so as to exert their action on the bearing surfaces of both soles. The platforms are attached to the feet by some sort of binding. The apparatus is provided with a programmed means of sequential control of the vibrators triggered in accordance with human walking pattern (Journal of neuropathology and psychiatry named after S. S. Korsakov, issue 8, Moscow, Meditsina Publishers, 1982 (in Russian) pp. 26-29 (1146-1149), "Application of vibro-stimulating footwear in complex treatment of postinsult patients" by I. V. Manekchina, A. S. Mirkin, L. G. Turbina, A. N. Vavilin, V. P. Ivannikov, L. A. Ivannikova, T. S. Ionova, V. K. Belokudrin).
The known apparatus lacks a means of accurately positioning the vibrators next to the bearing surfaces of the feet nd is incapable of stimulating the Achilles tendon. The stimulation of the bearing surfaces of the feet is poor, and the remedial effect of the apparatus is low.
Moreover, the soles are sites of numerous nerve endings and a misplaced vibrator can be an evil rather than asset, causing damage to organs.
SUMMARY OF THE INVENTION
The object of the invention is to provide a walking-simulating apparatus for person with restricted mobility wherein the platforms upon which the feet rest are of an improved design owing to which the bearing surfaces of the feet of any size are acted upon directly.
This object is realized by a walking-simulating apparatus for persons with restricted mobility incorporating two platforms upon which the feet rest and at least four mechanical vibrators located pairwise on each platform so as to exert their action on the bearing surfaces of both feet wherein according to the invention each of the platforms has a fore and a rear housing which can be translated relative to each other due to a mechanical actuator and a means of setting a distance between the fore and rear housings which is interlinked with the mechanical actuator.
It is expedient to provide each of the rear housings with an ankle piece attached thereto with provision for displacing up and down along the Achilles tendon there is a mechanical vibrator exerting its action on the Achilles tendon.
The mechanical actuator and the means of setting the distance between the fore and rear housings interlinked therewith can be provided in the form of a screw pair secured to the corresponding platform.
The apparatus can also be provided with a means of setting at least one of the mechanical vibrators on each of the fore housings into an appropriate position with respect to the bearing surfaces of the foot which is fitted to the fore housing at a side opposite to the corresponding rear housing.
