DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a device for capably measuring an actual angular deviation of a body axis and a method for controlling same around three body axes as centers of forward-backward bending and twisting movements of the body.
TECHNICAL BACKGROUND
Japanese Utility Model Publication No. 55-2,999, for example, describes a kind of athletic tool which has been conventionally known.
Such an athletic tool comprises a whirl-driven horizontal disc and a repeatedly fluctuating arc arm, the horizontal disc and the arm being actuated by a pair of motors to train the upper half of a trainee's body using changes in a relative position thereof under a condition in which the trainee on the disc grasps rings suspended from the arm.
With regard to a human body, it is well known that skeletal structures are joined by many joints which allow bending push-up and twisting movements. These movements comprise right-left leaning, forward-backward bending and right-left twisting of the body. It is also known that balance of mind and body as well as good health can be kept when these bending and twisting angles centering around the joints under a natural standing up condition are frontally symmetry and axes thereof are balanced each other.
Further, with regard to the control of unbalanced body axes, when body bending or twisting limits to both directions centering around a rolling axis (R), an pitching axis (P) and an yawing axis (Y) relating to the right-left leaning, forward-backward bending and the right-left twisting movements, respectively, show unbalanced measurements, it has been clinically confirmed that such an unbalance of either one of these axes (R), (P) or (Y) can be corrected by the forward-backward bending or twisting movements centering around the other two axes.
The above mentioned Utility Model only provides an athletic tool for training the upper half of a trainee's body. On the other hand, although the unbalance relating to the longitudinal, pitching and yawing axes, (R), (P) and (Y) as well as correction thereof are known in principle, any actual structure, tool or hardware for embodying this principle has not yet provided. As a matter of fact, it has been eagerly needed to develop a body axes measuring hardware and a method for controlling a body axis deviation.
Accordingly, it is an object of this invention to provide a device for measuring the body axes and a method for correcting the body axis deviation enough to meet such eager need.
DISCLOSURE OF THE INVENTION
The manner in which the above mentioned object of the present invention will be apparent from the following description. The most characteristic features of the present invention are:
1. A body axes measuring device comprising a means for regionally fixing a user's body and a means for detecting and measuring flection limits around a longitudinal, an pitching axis or an yawing axis while regionally fixing said user's body as a fulcrum;
2. A body axes measuring device as set forth in item 1, above, further comprising a means for fixing a user's waist and a means for recording changes in posture to both directions around at least one of a longitudinal, an pitching axis or an yawing axis of the use's waist;
3. A body axes measuring device as set forth in item 2, above, further comprising a horizontal circular flame, a backward-forward arc flame and a right-left arc flame with slides slidable on said flames for guiding an upper half of a user's body when the user changes posture thereof while keeping arm stretched, each of said flames having angular graduations and marking sleeves thereon;
4. A body axes measuring device as set forth in item 2 or 3, above, in which a guiding means for changing posture of an upper half of a user's body and a waist seat for fixing the user's waist are height-adjustable;
5. A body axes measuring device as set forth in item 1, above, further comprising foot discs for guiding angular changes of twisted legs to inner and outer directions around a user's groin joint and means for recording twist lim
