Shoulder stabilizing and strengthening method and apparatus

Abstract

A method and adjustable apparatus for stabilizing and strengthening the shoulder muscles and rotator cuff provides an active range of motion activities that can be performed with or without resistance. In particular, the method and apparatus provide for scapular retraction and protraction, shoulder flexion, extension, adduction and abduction, as well as internal and external shoulder rotation, performed horizontally and vertically. All of these motions are beneficial to the shoulder joint because they allow the joint to move freely throughout its normal range of motion using natural mechanics of the rotator cuff and surrounding muscles. The method and apparatus provide the essential benefit of stabilizing the shoulder and rotator cuff throughout these motions so that the user's range of motion and strength building is optimized. The method and apparatus also provide for self myofascial release techniques to decrease spasm.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to shoulder stabilizer apparatus and more specifically it relates to an adjustable apparatus to stabilize the shoulder and rotator cuff, thereby allowing an individual to optimize their shoulder range of motion and strength, as well as to allow for self myofascial release techniques to decrease spasm.

2. Discussion of the Related Art

It can be appreciated that shoulder stabilizer apparatus have been in use for years. Typically, shoulder stabilizer apparatus are comprised of an exercise device that is used for the development of the rotator cuff musculature of a user by isolating the head of the humerus in the glenoid cavity during internal and external rotation.

The main problem with conventional shoulder stabilizer apparatus is not having the shoulder stabilized in the most optimal position for strengthening the rotator cuff muscles. In particular, existing apparatus do not allow for resisted scapular retraction as well as adduction of the arm while fixated at 90 degrees, nor do they provide for resisted shoulder internal and external rotation. Also the prior art does not allow for scapular depression when the arm is at 90 degrees of shoulder abduction. Further, the prior art does not accommodate for resisted internal rotation which is usually twice as strong as that of external rotation. The apparatus is U.S. Pat. No. 4,817,943 allows for strengthening of the shoulder muscles, but does not allow for mobility and stabilization of the glenerohumeral joint which is essential in order to optimally strengthen the rotator cuff. The apparatus disclosed is U.S. Pat. No. 4,944,508 fails to teach the user to maintain a 90 degree angle of the arm and also has to be stabilized to a solid surface, such as a table. In addition, the prior art fails to provide proper stabilization of the humerus and also the availability to stabilize the shoulder blade, while strengthening the rotator cuff with interchangeable levels of the resistances. The disclosure in U.S. Pat. No. 5,058,574 is mainly concerned about fixating the position of the lower arm, rather than allowing for the proper stabilization of the scapula and the humerus which meet to form the shoulder joint.

Another short coming in the various apparatus of the prior art is the absence of a self myofascial release to the pectoral minor or levator scapulae in order to allow for optimal movement of the shoulder blade. This is essential to properly begin to scapular retract and adduct the arm at 90 degrees of elbow flexion in order to stabilize the glenerohumeral joint. Another problem with conventional shoulder stabilizer apparatus is the failure to allow for scapular depression with resistance of varying intensities in order to stabilize the shoulder joint when placed in a vertical position at 90 degrees of shoulder abduction.

While the numerous devices and apparatus of the prior ant may be suitable for the particular purpose to which they address, they are not suitable for individuals to be able to optimize their shoulder range of motion, strength building and stability, nor do they allow for self myofascial release techniques to decrease spasm.

The adjustable apparatus of the present invention is designed to stabilize the shoulder and rotator cuff in a manner that substantially departs from the conventional concepts and designs of the prior art and, in so doing, provides an apparatus primarily developed for the purpose of enabling a user to optimize their shoulder range of motion and strengthening while maintaining the shoulder stabilized. The invention also provides for self myofascial release techniques to decrease spasm. The adjustability of the apparatus allows the individual user to tailor his/her activities to their specific needs.

OBJECTS AND ADVANTAGES OF THE INVENTION

A primary object of the present invention is to provide an adjustable apparatus to stabilize the shoulder and rotator cuff throughout a variety of active motion activities to thereby overcome the shortcomings of the prior art.

Another object of the present invention is to provide an adjustable apparatus to stabilize the shoulder and rotator cuff to allow for individuals to be able to optimize their shoulder range of motion, strength and stability as well as to allow for self myofascial release techniques to decrease spasm.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the several views of the drawings, and initially FIGS. 13-19, the apparatus of the present invention is shown and is generally indicated as 10. The apparatus 10 is adjustable to perform various motion activities, as well as to accommodate individuals of varying height and size. The apparatus 10 is specifically structured to stabilize the shoulder and rotator cuff while simultaneously allowing the individual user to perform a variety of motion exercises (activities). Stabilizing the shoulder and rotator cuff throughout the exercises enables the individual user to optimize their shoulder range of motion and muscle strengthening when performing the exercises. The apparatus also allows for self myofascial release techniques to decrease muscle spasm.

As best seen in FIG. 1, the apparatus 10 includes a base 12, a vertical post 14, a sleeve 16 slideably adjustable throughout a range of adjusted positions on the vertical post 14, and arm assembly 18 adjustably fitted to the sleeve 16 so that the arm assembly 18 is movable with the sleeve throughout the range of vertically adjusted positions. A motion assembly 20 is adjustably fitted to the arm assembly 18 and includes a bottom plate 22, a middle plate 24 and a top plate 26. The top plate 26 is provided with a handle 28 for grasping with either the left hand or right hand to perform motion activities of the respective left or right shoulder. The base 12 is formed in a U configuration with opposite parallel legs extending from a central mounting portion to help stabilize and support the entire structure of the apparatus 10 on a floor surface. The vertical post 14 is attached to the central portion of the base and is provided with a series of spaced apertures for adjusted positioning of the sleeve 16 with the use of one or more removable locking pins. The sleeve slides up and down along the post for height adjustment of the arm assembly 18 and motion assembly 20 and is locked into the adjusted position on the post 14 using the removable locking pins which pass through correspondingly aligned apertures on the sleeve 16 and the post 14. The arm assembly 18 is removably attached to the sleeve by a knob bolt 40 and interconnecting tube sections 46, 48 which are structured to allowed adjustment of the pitch position of the motion assembly 20. The bottom plate 22 attaches to the arm assembly 18 by a pin which allows motion of the bottom plate 22 in the yaw direction. This motion allows for selected adjustment of resistance to movement of the top plate 26 when performing various motion exercises. Elastomeric cords may be used to provide increased resistance. The middle plate 24 slides relative to the bottom plate 22 along a track 25. Motion of the middle plate is along the longitudinal axis of the bottom plate. This motion allows for further selected adjustment of resistances of movement of the motion assembly 20 when performing motion exercises. One or more elastomeric cords 50 connecting to the bottom plate 22 and middle plate 24 and about a pulley 52, as seen in FIGS. 3,3A and 9,9A, may be used to provide this resistance. The handle 28 on the top plate is grasped by the individual user in order to perform motion in the yaw direction. The distance between the handle and the rotational axis of the top plate 26 is adjustable to the arm size of the individual.

The self myofascial release device 30 is provided with a rubber tip 32 on the end of an adjustable arm 34 that allows the rubber tip to be positioned at the required location to make pressure contact with either the levitator scapulae muscles or pectoral minor muscles when performing various motion activities.

In use, the user rests his/her arm on the top plate which includes a padded area for the elbow and the forearm. While holding the handle, the user adjusts the height of the motion assembly 20 by moving the sleeve 16 up or down along the post 14. When the motion assembly 20 is at the desired height position, the user locks the sleeve 16 into fixed, adjusted position on the post 14 with removable locking pins. Next, the pitch orientation of the motion assembly is adjustably fixed into position. This is performed using the knob 40 on the arm assembly 18. Next, the user moves the top plate 26 and the middle plate 24 backwards along the rail 25. Then, by rotating the bottom plate 22, the user can bring the elbow as closes possible to their side. Lastly, the user loosens knob 42, rotates the top plate 26 about its yaw axis and fixes the yaw position by tightening knob 42. All three motions (i.e. pitch, longitudinal sliding, and yaw) have selectable resistance which may be created with elastomeric cords or other tensioning mechanisms. In a different configuration, all three plates (i.e. bottom, middle, top) can be mounted vertically by rotating arm assembly 18 relative to the sleeve 14. Next, the user pulls down both the top plate 26 and middle plate 24, with selectable resistance against elastomeric cord 50, and performs shoulder rotation by rotating the top plate 26 relative to the bottom plate 22.

Referring now to FIGS. 1-12B, a series of shoulder motion and strengthening activities are shown. Each motion activity is shown in a pair of drawing figures with the first drawing figure in the pair showing a start position and the second drawing figure (labeled with a “A”) showing a stop position at the end of the full range of motion. After this stop position, the motion is returned back to the original start position.

FIGS. 1 and 1A show a sequence of movement of resisted external rotation, at 90° degrees, of the left shoulder with abduction and resisted scapular depression. The movement of resisted external rotation helps to strengthen the external rotators of the rotator cuff (infraspinatus) along with resisted scapular depression which helps to stabilize the head of the humerus in the shoulder joint (glenerohumeral joint). By performing these two activities together, the user achieves optimal stabilization and strengthening of the structures surrounding the shoulder joint.

FIGS. 2 and 2A illustrate a sequence of movement of a vertical row (i.e. shrug). This movement allows for strengthening of the trapezius muscle that is vital for shoulder stabilization. This movement also provides scapular elevation and active range of motion.

FIGS. 3 and 3A illustrate a sequence of movement for performing an resisted natural grip row with scapular retraction and adduction. This activity allows the user to strengthen the stabilizing muscles that surround the shoulder complex. Additionally, this motion activity provides for mobility and range of motion of the shoulder joint, scapula and surrounding musculature.

FIGS. 4 and 4A illustrate a sequence of movement in performing a natural grip shoulder press. Performing this movement allows the user to safely and effectively strengthen the anterior and medial deltoid muscles with variable resistance.

FIGS. 5 and 5A illustrate a sequence of movement in performing in abduction active range of motion exercise of the left shoulder. This movement allows the individual to perform left shoulder abduction active range of motion with varying resistance and degrees of range of motion.

FIGS. 6 and 6A illustrate a sequence of movement in performing a self myofascial release (SMR) activity to the levitator scapulae muscles. By performing an SMR activity to the levitator scapulae muscles, the individual is able to relieve the levitator muscles of any tension or tightness that may exist, along with allowing the shoulder blade the ability to return to a resting position. FIGS. 7 and 7A illustrate a sequence of movement in performing a self myofascial release SMR activity to the pectoral minor muscles. With the SMR to the pectoral minor, this movement allows the chest muscles to ultimately relax, thus allowing the shoulder blade to return to a normal resting position. Both SMR activities, as shown in FIGS. 6-6A and 7-7A, will allow for decrease tension to the cervical spine and cervical musculature along with providing increased range of motion to the cervical spine. The SMR activities also provide increased range of motion to the shoulder blade, which is essential for optimal functioning of the shoulder joint.

FIGS. 8 and 8A illustrate a sequence of movement in performing a resisted scapular retraction with resisted shoulder internal rotation. These two movements allow strengthening of the rotator cuff (subscapularis) muscles. Resisted scapular retraction allows for the proper alignment of the shoulder joint, thus providing optimal shoulder orientation for strengthening of the rotator cuff with resisted internal rotation activities.

FIGS. 9 and 9A illustrate a sequence of movement in performing a resisted row with scapular retraction with a reverse incline. FIGS. 10 and 10A illustrate a sequence of movement in performing a resisted row with scapular retraction at a reverse decline. Both of these movements illustrate the extreme flexibility and variability of the apparatus 10, wherein the scapular stabilizing muscles can be further strengthen with resisted growing and scapular retraction activities while the arm and shoulder are position at varying angles. This allows for strengthening the shoulder complex and surrounding structure throughout the shoulder and rotator cuff full functional capacity and active ranges of motion.

FIGS. 11 through 11B illustrate a sequence of movement in performing a resisted scapular retraction along a horizontal row with both resisted internal and external rotation. This motion is beneficial to the user because it allows for optimal alignment of the shoulder joint along with resisted scapular retraction/protraction, resisted shoulder internal and external rotation, as well as resisted rowing and pressing activities. All of these motions help to stabilize and strengthen the shoulder joint particularly with resistance.

FIGS. 12 through 12B illustrate a sequence of movements to perform a resisted scapular depression with resisted internal and external rotation at a 75° degree incline. This motion is beneficial because it allows the user to depress the shoulder blade (scapula) with or without resistance. With depression of the shoulder blade, the shoulder joint is able to optimally glide and spin as a ball and socket joint. With resisted scapular depression, the user is able to properly and safely strengthen the muscles that are needed for maintaining the shoulder blade in its proper position for optimal joint function. Resisted scapular depression will also allow decreased tension to the cervical spine, as well as the cervical musculature.

While the present invention has been generally shown and described in accordance with a preferred and practical embodiment thereof, it is recognized that departures from the instant disclosure are contemplated within the spirit and scope of the present invention.
