FIELD OF THE INVENTION
The present invention relates generally to the field of medical braces, and more particularly to methods and systems for shoulder braces with controlled range of motion.
BACKGROUND OF THE INVENTION
When a shoulder is injured and healing, abrupt stops of motion are a main cause of discomfort and pose a risk of further injury. In the first few weeks of healing post-surgery, shoulders should not move to avoid unnecessary pain and discomfort while also protecting the shoulder. In the next 2-3 months, the shoulder should begin to stretch and have regulated movement in comfortable positions. And finally, the shoulder should be conditioned post therapy by applying a loaded force for the shoulder to work and strengthen against. However, shoulder braces currently available in general cannot prevent movement or control movement of the shoulder, and are also incapable of providing assistance in the conditioning and strengthening of the shoulder.
As such, considering the foregoing, it may be appreciated that there continues to be a need for novel and improved devices and methods for shoulder brace devices.
SUMMARY OF THE INVENTION
The foregoing needs are met, to a great extent, by the present invention, wherein in aspects of this invention, enhancements are provided to the existing model of shoulder brace devices.
In an aspect, a shoulder brace device can include:
- a) a torso band;
- b) an arm band; and
- c) a brace mechanism, which can include:
- i. a main plate, which can be configured to connect to the torso band; and
- ii. an arm plate, which can be configured to connect the arm band;
- such that the brace mechanism can be positioned between an arm and a body of a user, wherein the main plate and the arm plate can be rotatably connected;
- such that the brace mechanism can enable free range of movement of the arm, such that the user can move their arm to adjust the brace mechanism to a comfortable position;
- such that the brace mechanism can be configured to be lockable in the comfortable position to prevent injuring motions to a healing shoulder.
In a related aspect, the brace mechanism can include:
- a) a ball joint assembly, which can include:
- i. a ball joint arm, which can be connected to the arm plate, wherein the ball joint arm can include a ball that is offset perpendicularly from an end of the ball joint arm; and
- ii. a ball joint mounter, which can be attached to the main plate, such that the ball joint mounter can be configured to receive the ball of the ball joint arm, such that the ball joint arm can be secured and freely rotatable within the ball joint mounter;
- wherein the ball joint assembly can enable the arm plate to freely rotate with respect to the main plate.
In a further related aspect, the brace mechanism can further include:
- a) an adjustment assembly, which can include:
- i. a screw, which can be insertable through lower ends of the left mounting piece and the right mounting piece; and
- ii. an adjustment knob, which can include a twisting structure, such that the twisting structure can be configured to twist the screw;
- such that when the screw is twisted clockwise by the adjustment knob, the screw can move the left mounting piece closer to the right mounting piece, such that friction force around the ball in the ball shaped chamber can increase;
- such that when the screw is twisted counterclockwise by the adjustment knob, the screw can move the left mounting piece further from the right mounting piece, such that the friction force around the ball in the ball shapes chamber can decrease;
- such that the adjustment assembly can be completely loosened to allow for free range of movement, such that the adjustment assembly can be completely tightened to lock the ball joint arm in the comfortable position;
- such that the adjustment assembly can be gradually loosened or tightened to lower or increase range of movement.
There has thus been outlined, rather broadly, certain embodiments of the invention in order that the detailed description thereof herein may be better understood, and in order that the present contribution to the art may be better appreciated.
