Equipment to assist the carrying out of flexion exercises of the cervical zone of the spinal column

Abstract

An equipment comprising a body ( 1 ) that defines a seating ( 2 ) intended to encircle the head of the user, within said body there being provided an annular channel ( 5 ) that runs around the seating ( 2 ) and accommodates at least one cursor ( 6 ) arranged in a fully mobile manner, so that to a rotatory movement of the user's head around the axis of the spinal column there corresponds a motion of said cursor ( 6 ) along said channel ( 5 ) and the user, perceiving the vibrations and/or the noise produced by said motion, receives indications regarding the symmetry and uniformity of the rotatory movement of his head.

1 . An equipment comprising: a body; a seating defined by said body, said seating being intended to fit onto the upper part of the head of a user; an annular channel formed within said body, said channel running around said seating; and cursor means arranged in a fully mobile manner in said channel, whereby to a rotatory movement of the user's head around the axis of the spinal column there corresponds a motion of said cursor means along said channel and the user, perceiving the vibrations and/or the noise produced by said motion, receives indications regarding the symmetry and uniformity of the rotatory movement of his head.  
     
     
         2 . An equipment according to  claim 1 , wherein the surface of the channel and/or that of the cursor means is at least partially roughened, so as to increase the noise produced by the motion, the uniformity of which will be perceived by the user as a function of the symmetry and uniformity of the rotatory movement of his head.  
     
     
         3 . An equipment according to  claim 1  or  claim 2 , wherein said cursor means are constituted by at least one rolling element that rolls along the channel.  
     
     
         4 . An equipment according to  claim 3 , wherein said channel is defined by a tube of circular cross section that is bent into a ring, said at least one rolling element being ball-shaped.  
     
     
         5 . An equipment according to  claim 4 , wherein said tube is corrugated.  
     
     
         6 . An equipment according to  claim 4 , wherein said tube is wrapped in a lining made of soft material, such as foam rubber.  
     
     
         7 . An equipment according to  claim 3 , wherein said tube comprises means for regulating the length of its circumference.  
     
     
         8 . An equipment according to  claim 1 , wherein said cursor means have a weight such as to increase the muscle-strengthening effect associated with the rotatory movement of the user's head, in proportion to said weight increase.  
     
     
         9 . An equipment according to  claim 1 , wherein the position of said body on the user's head is rendered more stable and secure by at least one strap that extends diametrically within said seating and can be adjusted in length so as to fit tightly around the user's head.  
     
     
         10 . An equipment according to  claim 9 , wherein said body comprises a plurality of rings evenly spaced around the circumference of said seating and suitable for permitting the attachment of said at least one strap.  
     
     
         11 . An equipment according to  claim 1 , wherein said cursor means are magnetized.  
     
     
         12 . An equipment according to  claim 1 , comprising also ear-protecting means attached to said annular body in such a way as to fit against the ears of the user in order to amplify said vibrations and/or noise.  
     
     
         13 . An equipment according to  claim 12 , wherein said ear-protecting means are part of an anti-noise headset, a semicircular element linking the ear-protecting means being attached to said body and extending diametrically above said seating.  
     
     
         14 . An equipment according to  claim 1  or  claim 2 , wherein said cursor means are constituted by a mass of grains or pellets capable of producing a noise of shaken sand.
