Comparing the Efficacy of Transforaminal Epidural Injections, Acupuncture and Platelet Rich Plasma Injection in Patients with Sciatica Due to Intervertebral Disc Herniation, Spinal Stenosis and Spondylolisthesis

Steroid injection, acupuncture and platelet-rich plasma injection are often used interventions for the treatments of sciatica. The investigators will investigate the efficacy and safety of steroid injection, acupuncture and platelet-rich plasma injection for sciatica in this single center, parallel, randomized-controlled clinical trial.

Participants will be randomized into 3 groups (steroid injection, acupuncture and platelet-rich plasma injection) by central allocation. Randomized participants will complete a questionnaire that solicited information regarding age, sex, marital status, occupation, education, and medical history. The blinding credibility of the treatments will be evaluated at the end of the treatment.

Participants in steroid injection group will receive Triamcinolone 1pc plus lidocaine 1% 1cc injection at neuritis nerve roots. Participants in platelet-rich plasma injection group will receive 15cc blood draw first to concentrate into platelet-rich plasma and then inject at neuritis nerve roots. Participants in acupuncture group received standardized acupuncture treatment. hat treatment was accomplished by selecting a group of acupuncture points that predefined. Acupuncture points will be bladder meridian pattern acupuncture points including Shenshu (BL23), Qihaishu (BL24), Dachangshu (BL25), and Guanyuanshu(BL26). The needles will be inserted perpendicular to a depth of 5 to 35 mm depending on the acupuncture point, which was followed by manual stimulation by bidirectional rotation to induce Deqi sensation. Deqi was defined as a dull, localized, and aching sensation, which signaled the attainment of qi.

Outcome Measures Primary Outcome Measure The primary outcome measure is visual analogue scale for sciatica. To understand the impact of sciatica on the participants' life, visual analogue scale for bothersomeness is chosen instead of pain intensity. The participants will be asked to mark, on a 10 cm visual analogue scale (0, absence of bothersomeness; 10, the worst bothersomeness imaginable), the average degree of bothersomeness due to sciatica experienced within the most recent 1 week from the day of the assessment. This measurement has substantial validity. Bothersomeness of sciatica will be measured at baseline, 1-, 2-, 4-, 8-, 12-, 16-, and 24-week.

Secondary Outcome Measures Numeric Rating Scale for pain intensity is a simple method evaluating the subjective intensity of pain. Pain intensity will be measured in the same way as visual analogue scale for bothersomeness. Validity of its reliability has been demonstrated. The Chinese version Oswestry Disability Index is used to measure back pain-related dysfunction. Health-related quality of life will be measured using the well-validated EuroQol 5 dimensions (EQ-5D). A higher score is indicative of a better general health status. Participants satisfaction will be evaluated with 5 point scale (1 is worst, and 5 is best)
