Indications for Use

PainTB and PainTJ Laser systems are indicated for adjunctive use in the temporary relief of low-back pain and wrist pain associated with Carpal Tunnel Syndrome.

Device Story

PainTB and PainTJ are semiconductor laser systems (Class 3B) used for pain relief. Devices emit three wavelengths (670nm, 830nm, 910nm) via diode laser modules; wavelengths cross-irradiated to prevent overlap. Operated via smartphone app for monitoring usage duration and frequency. Used by patients or clinicians to irradiate painful areas (low back, wrist). Treatment times selectable (20/40/60 minutes). Powered by internal 3.7V lithium polymer battery; rechargeable via adapter. Provides non-heating infrared light therapy to assist in pain management. Clinical benefit demonstrated through reduction in VAS pain scores.

Clinical Evidence

Prospective, rater-blind, randomized study (n=60 adults with back pain, VAS score ≥4). Compared active laser + exercise vs. mock laser + exercise. Primary endpoint: change in VAS pain score. Results showed statistically significant difference between groups (p < 0.05). No adverse effects reported.

## 8. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE

The mechanism for pain treatment using Non-heating Infrared ramp has been studied for a long time, and various products have cleared FDA 510(K) and are being used as medical devices for treatment. Our product have three wavelength's diode laser(670nm, 839nm, 910nm) and they are cross irradiated so don't be overlay to another wavelength when it is working. Also, each wavelength is generally used in pain treatment, and we can easily find similar product in the market.

The following is the result of comparing our product with the similar product in clinical literatures chosen. At the technical aspect, light sources and wavelength optical power were compared. The similar product used diode Laser and its wavelength was 830nm so it is same wave length as ours. Optical power of similar product is 30mW and our 830nm is 24.1mW so it is within the acceptable range. Thus, this product and our product have technical equivalence. In addition, the application range and the effect of the product were compared at the clinical aspect. The predicate device was used at pain treatment and reduced pain so it is same as ours. Thus, this product and our product have clinical equivalence.

There is some gap in comparison with similar products because our product have 2 more wavelength laser used. Although 830nm is major and other 670nm and 910nm laser is lower power for supporting performance of the treatment, it is showing gap with predicate device.

## 10. Summary of Clinical Information

The PainTB was evaluated in a prospective, rater blind, randomized study that compared the "Active" Laser with a "Mock" Laser. The single-center study was conducted in the South Korea. In the test, 60 adult patients of back pain whose VAS score is 4 or higher are recruited as subiects. PainTB alone test and exercise treatment combined with PainTB use and "Mock" device use are conducted, and VAS measurement has used as pain level scale.

### Clinical Data Analysis and Results

Statistical analyses (one-way ANOVA) were performed by generally accepted statistical techniques to evaluate the differences between the VAS scores before and after treatment follow up for patients in Group B (Active Laser + exercise treatment) and Group C (Mock Laser + exercise treatment).

The statistical analyses of the data demonstrate that the difference between the two treatment groups over time is statistically significant (p-value < 0.05).

No adverse effects from the laser treatments were observed by the principal Investigators during the clinical investigational study.

## 11. Conclusion

In conclusion, PainTB/PainTJ and predicate device are products with the same technical characteristics and IFU that share the same. Although there are some gap, with reviewing the submitted clinical report, it can be seen that the gap does not affect basic effectiveness and safety equivalence of the products, it is also effective for low back pain.
