A CORE STABILIZER WITH A BIOFEEDBACK SYSTEM

FIELD OF THE INVENTION:

The present invention relates toa core stabilizer with a biofeedback system. Particularly it relates to a core muscles stabilizer with a visual biofeedback system to improve the core (proximal) muscles stability and distal functional mobility from a lumbosacral structure.

BACKGROUND OF THE INVENTION:

There are so many adults that suffer from low back pain, and it is the second most common reason people seek a doctor. 90% people, once in their lifespan complains about low back pain. This health problem results in chronically disabled and temporarily on disability. Lower back pain affects the spine's stability, flexibility, and strength, as a result, causes pain, discomfort, and stiffness during daily living activities such as sitting, driving, or sleeping. A great majority of back pain experienced by the general population occurs in the lower portion of the back generally referred to as the lumbarscaral area or the spinal segments L-3 through S-1 specifically.

To comprehend the most causes of low back pain, it is essential to understand the functioning of the spinal column. The purpose of the human spinal column is to support and protects the body. The most common area of low back pain is at the spinal process segment L-3 to S-1. The spine process is composed of twenty-four individual vertebrae. Each vertebra is attached and support by cartilages, ligaments andmusclesto allow flexibility to bend over, and rotate the torso. Each vertebra is connected by an intervertebral disc that functioning to provide cushion and prevent compression to the peripheral spinal nerves.

Whenever there is an inactive life style, poor ergonomics and structural derangement further leads to muscles weakness at spine. Such structural derangement prone to lead herniated discs, spinal stenosis, fractures, osteoarthritis, or injury, it presses against the spinal nerves, and as a result, it stimulates pain during daily living activities such as sitting, sleeping, driving or bending.

For example, people, working over a desk, generally sit in front of a computer for a long time. Keeping the head forward becomes a normal state both in work and life, which brings large loads to the spine; as a result, it is likely to cause spinal abnormality. Static life style and lack of physical activity lead to non use muscles wasting. The spinal abnormality may not only cause neck pain, shoulder pain, back pain, and numbness of limb but also affect blood vessels near the spine and disrupt nerves managing the viscera, thereby resulting in the disorder of breath, digestion, circulation, and other systemic functions. Consequently, many people are in ailment or sub-health status, and the quality of work and life is influenced seriously.

Likewise, low pain back is also caused by, the shifting of the vertebrae caused by unequal strength of the muscles supporting the spine column specially lumbosacral joint which is responsible for maximum movements. Stability at lumbosacral joint helps to maintain static core stability and extend dymaci mobility at distal stundetues such as legs and feets and arms and hands. This can occur due to overuse or injury of the muscles or ligaments, uneven muscular stress, emotional tension. The majority of low back pain is managed with conservative treatment such as rest, analgesic, anti-inflammatory medications in conjunction with physical therapy to strengthen the back muscles to support the spinal column to relieve pain or eliminate it.

There are many types of exercise devices available in the market lacing of feedback system. Another conventional treatment used to address back pain due to injury or non-injury is applying pressure to the area with orthopaedic belt devices.

CA2965181A1discloses a low back pain solution device design for individuals with acute or chronic lower back pain, individuals who are post-spinal surgery, or individuals who are pregnant and are experiencing low back pain or back injury. The device allows a user to continuously wear something that is both comfortable and discrete. The device accomplishes this task by flanking a user’s lumbar and erector spinae muscles with soft yet firm cushions. This protects a user’s lower spine processes and peripheral nerves from being touched by any object that has the potential to compress it during sitting, sleeping, or driving.

The problems associated with some of these devices become too complex to use. Muscle strength provides core (structural) stability and peripheral (functional) mobility. There is a certain need to develop a “Core Stabilizer – Exercise Therapy Instrument” to improve the core stability at lumbosacaral spine and functional mobility at distal structures. Moreover, integrating visual or auditory biofeedback within the instrument has an advantage for the individual to practice independently and correctly.

Furthermore, non-permanent pieces of equipment are often difficult to disassemble and may require much storage space even when disassembled. A user must then often choose between an exercise device providing a complete exercise regime and a device that fits the exerciser’s space. There is, thus, a need for exercise equipment that may be easily stored when not in use, does not occupy a great deal of space when in use, and provides for exercising all or most of the muscle groups.Therefore, the inventors of the present invention come up with the unique, low-cost, easy to access core stabilizer for the low back exercise.
