510K-Certified Lumbar Traction & EMS Device: Clinical Relief for Lower Back Pain

Lumbar problems have become a prevalent musculoskeletal disease among the general population. According to clinical orthopedic diagnosis and treatment data, the incidence of lumbar disc herniation and lumbar muscle strain among sedentary people exceeds 70%, and the detection rate of straightening of the physiological curvature of the lumbar spine in adolescents is rising year by year. 

Mild cases cause low back soreness and limited mobility, while severe cases lead to numbness and radiating pain in the lower limbs due to intervertebral disc compression of nerve roots, and even affect walking function. 

In response to the clinical diagnosis and treatment needs of lumbar problems,OSTO MEDICAL has deeply engaged in the research and development of rehabilitation equipment and launched the MODEL AST-623B Lumbar Traction EMS All-in-One Device. 

Based on the core design of clinical rehabilitation medicine in orthopedics, it integrates two technologies: dynamic lumbar traction and EMS electric pulse physiotherapy, and has passed the US FDA 510K certification.

Its safety and effectiveness have been verified by clinical tests, making it a professional choice for home lumbar treatment and rehabilitation, and providing a scientific and feasible solution for patients with different degrees of lumbar problems.

From a clinical medical perspective, the pathological core of lumbar problems is mostly the result of the dual effects of lumbar biomechanical imbalance and muscle strength imbalance of the low back muscle group: 

long-term sedentary and bad postures such as bending over will lead to the loss of the physiological curvature of the lumbar spine (straightening or kyphosis), and the narrowing of the intervertebral space will increase the pressure on the intervertebral disc, causing nucleus pulposus herniation; 

at the same time, the deep stabilizing muscles of the waist (such as multifidus muscles and erector spinae muscles) undergo atrophy and spasm due to long-term disuse, failing to provide effective support for the lumbar spine, further aggravating lumbar degeneration and forming a vicious circle of "pain - muscle tension - mechanical imbalance". 

Ordinary massagers can only act on the superficial muscles of the waist and cannot solve the clinical core problems of intervertebral space pressure and deep muscle group repair; although professional hospital traction treatment can open the intervertebral space, it is limited by diagnosis and treatment time and region, making it difficult to achieve sustained rehabilitation and affecting the treatment effect.

The MODEL AST-623B Lumbar Traction EMS All-in-One Device of OSTO MEDICAL strictly follows the three-step diagnosis and treatment principle of "Decompression - Repair - Stabilization" for clinical lumbar rehabilitation in orthopedics, perfectly integrating hospital-grade clinical rehabilitation technology with home convenience to solve lumbar problems from the pathological root:

Clinical-grade dynamic lumbar traction: precise decompression, restore lumbar biomechanical structure

Referring to the clinical standard of continuous gentle traction in orthopedics, the equipment adopts an ergonomic curved surface design that fits the physiological curvature of the lumbar spine. It accurately opens the intervertebral space by 3-5mm through slow and controllable traction force. 

This traction amplitude has been clinically verified to effectively release the pressure of the intervertebral disc on the nerve root, relieve clinical symptoms such as numbness and radiating pain in the lower limbs, and avoid lumbar ligament damage caused by excessive traction. 

It is suitable for common clinical lumbar problems such as mild/moderate lumbar disc herniation, straightening of the lumbar curvature, and lumbar facet joint disorder. Clinical data shows that standardized traction for 15 minutes a day can reduce the pressure inside the lumbar intervertebral disc by 40%-60%, effectively improve the narrow lumbar intervertebral space, and gradually restore the normal physiological curvature of the lumbar spine.

Medical-grade EMS electric pulse physiotherapy: deep repair, rebuild the supporting force of the waist muscle group

Equipped with the low-frequency modulated medium-frequency electrical stimulation technology commonly used in clinical rehabilitation departments, multi-gear EMS electric pulses can penetrate the superficial muscles of the waist and reach the lumbar stabilizing muscles (multifidus muscles, erector spinae muscles, quadratus lumborum muscles) as deep as 3-5cm. 

By simulating nerve electrical signals to stimulate muscles for rhythmic contraction and relaxation, it can quickly relieve muscle spasm, eliminate soreness and pain caused by lumbar muscle strain, and activate atrophied deep muscle groups to improve muscle strength and endurance. 

Clinical studies have shown that continuous EMS electrical stimulation training can increase the strength of the deep lumbar muscles by more than 30% within 4 weeks, rebuild the muscle support system of the lumbar spine, fundamentally solve the problem of lumbar biomechanical imbalance, and effectively reduce the recurrence rate of lumbar problems.

The [AST-805B] Lumbar Traction EMS All-in-One Device has successfully passed the US FDA 510K certification which means that the product's materials, craftsmanship and functional effects all meet the international medical-grade rehabilitation equipment standards. Its core indicators such as traction force, EMS electric pulse parameters and fuselage fit have all passed strict clinical tests.

 It is radiation-free, non-invasive and has no obvious side effects. It is suitable for the concept of "sustained home rehabilitation" recommended by clinical orthopedics. 

Different groups such as the elderly, adolescents and sedentary office workers can use it with confidence, truly realizing "clinical-grade treatment, home-style enjoyment".

As a professional lumbar rehabilitation equipment verified by clinical tests, the MODEL AST-623B Lumbar Traction EMS All-in-One Device has accumulated a large number of real and effective treatment cases in clinical application and actual use, covering different ages and types of lumbar problems, and its improvement effect is in line with the clinical diagnosis and treatment evaluation standards:

●  Case 1: 38-year-old Mr. Zhang, Internet Operation Specialist | Clinical Diagnosis: Mild L4-L5 Lumbar Disc Herniation, Lumbar Muscle Strain

Clinical Symptoms: Stabbing pain in the lower back after sitting for a long time (VAS pain score 6 points), numbness on the lateral side of the right leg, limited bending, and inability to work in the office for more than 1 hour a day. 

Used the MODEL AST-623B once a day for 30 minutes with the clini cally recommended "moderate traction (25N) + deep muscle group EMS stimulation" mode.

After 2 weeks of persistence, the VAS score of low back pain dropped to 2 points, and the numbness in the right leg disappeared completely; after a 4-week clinical rehabilitation cycle, lumbar CT reexamination showed that the width of the L4-L5 intervertebral space returned to normal, the symptoms of lumbar muscle strain were cured, and he could work in the office for a long time without further hospital outpatient traction treatment.

●  Case 2: 52-year-old Aunt Li, Housewife | Clinical Diagnosis: Chronic Lumbar Muscle Strain, Mild Straightening of the Physiological Curvature of the Lumbar Spine

Clinical Symptoms: Persistent soreness and stiffness in the lower back, aggravated on rainy days (VAS pain score 5 points), low back fatigue after standing for a long time (more than 30 minutes), and inability to complete housework such as mopping the floor and bending over to wash vegetables. 

Used the MODEL AST-623B with the "gentle traction (15N) + lumbar muscle relaxation EMS mode", once a day before going to bed for 12 minutes. 

After 3 weeks of persistence, the low back stiffness was completely relieved, the VAS pain score dropped to 0 points, and she could complete housework normally. Lumbar lateral X-ray examination showed that the physiological curvature began to recover; after continuous use for 2 months, the strength of the core lumbar muscles was significantly improved, and there was no discomfort when sitting or standing for a long time.

●  Case 3: 26-year-old Mr. Zhou, College Student | Clinical Diagnosis: Straightening of the Physiological Curvature of the Lumbar Spine, Disuse Atrophy of the Low Back Muscle Group

Clinical Symptoms: Soreness and pain in the lower back when getting up in the morning, stiffness in the lower back after sitting for a long time to do exercises, a pulling feeling in the lower back when bending over, and clinical tests showed that the strength of the deep low back muscles was only 60% of the normal level. 

Used the adolescent-specific clinical spine care mode of the MODEL AST-623B, once a day for 30 minutes, with low-force traction (10N) combined with mild EMS electrical stimulation. 

After 1 month of persistence, the soreness and pain in the lower back when getting up in the morning disappeared completely, and there was no pulling feeling when bending over; after 3 months of persistence, clinical muscle strength tests showed that the strength of the deep low back muscles recovered to 85% of the normal level, the physiological curvature of the lumbar spine basically returned to normal, effectively avoiding the further development of lumbar problems into lumbar disc herniation.

●  Case 4: 45-year-old Mr. Wang, Driver | Clinical Diagnosis: L3-L4 Lumbar Disc Bulge, Lumbar Facet Joint Disorder
