Discogen 治疗腰痛
Discogen 装置缓解椎间盘源性背部/根性腿部疼痛的双盲试点可行性研究
This study will be a double-blinded, two-arm, prospective, randomized controlled pilot feasibility study in 40 evaluable subjects (20 in each arm) at one study site within the United States. Subjects in Arm 1 will receive unilateral Discogen treatment; subjects in Arm 2 will receive unilateral sham treatment (control). Treatment in both arms can include medications, e.g. NSAIDs or muscle relaxants for axial or radicular pain.

This study will be a double-blinded, two-arm, prospective, randomized controlled pilot feasibility study in 40 evaluable subjects (20 in each arm) at one study site within the United States. Subjects in Arm 1 will receive unilateral Discogen treatment; subjects in Arm 2 will receive unilateral sham treatment (control). Treatment in both arms can include medications, e.g. NSAIDs or muscle relaxants for axial or radicular pain. This study will enroll 40 evaluable subjects and follow them for 60 days.
-
Investigate the safety and feasibility of the Discogen device to alleviate back/radicular leg pain
-
Assess the mean reduction in back and radicular leg pain following Discogen treatment.
-
Primary Safety - collection of all adverse events, including any device- or procedure-related adverse events
-
Primary Effectiveness -percent change from baseline for Numerical Pain Scale (NPS) radicular leg pain at 30 and 60 days. The scale ranges from 0(No pain) to 10 (Severe pain).
-
Secondary Effectiveness:
- Change from baseline in Oswestry Disability Index at 30 and 60 days. The Index ranges from 0-20% (minimal disability), 21-40% (moderate disability), 41-60% (severe disability), 61-80% (crippled), to 81-100% (bed bound).

|---|---|
|
实验性的：Treatment Group
Study subjects in the treatment group (Arm 1) will receive 3 daily Discogen treatments unilaterally within a one week (M-M) period, each lasting 25 minutes. |
The device is a customized Low Intensity Pulsed Ultrasound (LIPUS) transducer system and power source. The transducer is biocompatible for skin contact. The system is capable of calibration to desired treatment parameters. The study subject will be placed in the prone position with all appropriate pressure points padded on the exam table. For the first treatment, fluoroscopic imaging (and/or ultrasonic guidance) will be used to guide the placement of the transducer over the anatomic target, unilateral at the L3-4, L4-5 or L5-S1 levels. The skin of the study subject's back will be marked with non-washable marking pen to indicate the site for placing the transducer during the first treatment. The subsequent treatment (second and third) can be done without using ultrasound guidance. The transducer will be placed on the marked site during the second and third treatment. The ultrasound signal will be delivered unilaterally for 25 minutes, using a timer visible to the patient. The power ge |

假比较器：Sham Control Group
Subjects in the sham control arm (Arm 2) will receive 3 daily non-powered treatments unilaterally within a one week (M-M) period, each lasting 25 minutes |
The ultrasound signal will be delivered unilaterally for 25 minutes, using a timer visible to the patient. The power generator will not be turned on for the sham treatment, but the wave generator will be displayed. All study subjects will receive a total of three daily Discogen treatments over the span of a single M-M work week |
