An interventional study of CGM MB-1701 device treatment and CGM MB-1701 Sham device treatment in Cervical Kyphosis, Cervical Lordosis and Kyphosis, sponsored by Ceragem Clinical Inc.. Completed at 1 site in South Korea. Open to participants aged 19 Years and older. Per ClinicalTrials.gov, last updated 2026-02-09.

The study is a Prospective, Randomized, Single-blinded, Sham device controlled, Parallel Treatment Grouped, Multi-center, Exploratory Clinical Trial to Evaluate Improvement of Cervical Lordosis and Safety of CGM MB-1701 (Spinal warm massage device, Ceragem Master V6) in Subjects with Cervical Kyphosis and Posterior Neck Pain.
The Cervical Kyphosis are also commonly referred to as "turtle neck syndrome." It refers to the deformation of the neck bone into an inverted C-shape due to abnormalities or degenerative changes, and it is named to mean that the neck is bent like a turtle.
This device, Ceragem Master V6 (CGM MB-1701), has been certified as a combination of a personal warmer that can be used to relieve muscle pain by applying constant heat to the human body and a medical vibrator of a device that applies physical energy (vibration, shock, pressure, etc.). Also, the device got approval for use with intermittent pneumatic compression and electrically-powered orthopedics traction.
The primary purpose of this clinical trial is to confirm the temporary cervical lordosis angle improvement (height) in subjects with cervical kyphosis through the combined function of the test device.
132 studies on the registry are indexed under Kyphosis; 31 are open to participants now.
This study's enrollment of 30 is below the median of 44 across 82 interventional studies indexed under Kyphosis.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Subjects will be treated with the study device for about 36 minutes.
Device: CGM MB-1701 device treatment
Subjects will be treated with the Sham device for about 36 minutes.
Device: CGM MB-1701 Sham device treatment
This is a pre-approved motorized traction device.
It is manufactured in the same way as the test device and the operation pattern. However, the actual effect of the massage is minimized.
Mean change of cervical lordosis
Mean change of cervical lordosis using posterior tangent method of Harrison measured by cervical lateral radiography at EOT (End of Trial) compared to baseline.
Time frame: up to 16 weeks
Change of cervical lordosis at 2nd interim analysis
Change of the cervical lordosis (posterior tangent method of Harrison) measured by cervical lateral radiography at the 2nd interim visit compared to baseline.
Time frame: up to 16 weeks
Cervical vestibular angle increase more than 10 degrees
The fraction of subjects whose cervical vestibular angle measured by the posterior tangent method of Harrison at each time of evaluation increased by more than 10 degrees compared to the baseline
Time frame: up to 16 weeks
Anteroposterior (T1) slope average change
Average change in cervical anteroposterior (T1) slope measured by cervical lateral radiography at each evaluation compare to the baseline
Time frame: up to 16 weeks

Ran from May 2023 to primary completion in Jul 2024, 14 months.
Of 58 interventional studies with no phase under Kyphosis, half reached primary completion within 9 months of starting (the median), counting those still running; a quarter within 4 and three quarters within 30. This study's 14 months is above that.
