Experimental: Verum Electroacupuncture
Other: Real Acupuncture with Electrical Stimulation
Acupuncture is a therapy commonly used in East Asian countries, where the practitioner insert thin needles at specific body sites in order to relieve pain and illnesses. Recent studies found low frequency electricity applied through acupuncture needles can lead to profound pain relief by increasing endorphin levels in the central nervous system. Electroacupuncture will thus be used as the active intervention to treat chronic low back pain in this clinical study.
Placebo Comparator: Placebo Electroacupuncture
Other: Simulated Acupuncture with Electrical Stimulation
This intervention serves as the placebo control of the active intervention. Sterile acupuncture needles and the ITO electrical stimulators will be used in this intervention. But special care will be taken to have this intervention mimic the real treatment yet remaining as physiologically inert as possible.
- Mean back pain intensity by patient-report [ Time Frame: 7 days ]Patient self-reported mean back pain intensity on 11 point (0-10) numerical rating scale (NRS).
- Roland Morris Disability Questionnaire [ Time Frame: 1 day ]Validated functional outcome measure in chronic low back pain with 24 yes/no questions regarding physical function.
- Quantitative Sensory Testing [ Time Frame: Tests used are typically stable for 1-2 weeks ]Standardized response to noxious thermal and mechanical stimuli up to 120 seconds.
- Physical exam to determine neurological function [ Time Frame: 1 month ]Physical exam assessing neurological function (recorded as presence or absence of light touch sensation, and stretch reflexes at the knees and ankles) in up to 5min.
- Physical exam to assess lumbar facet irritation. [ Time Frame: 1 month ]Physical exam assessing facet irritation via positive or negative response to lumbar facet maneuver in up to 5 minutes.
- Physical exam to assess lumbar spine range of motion [ Time Frame: 1 month ]Physical exam assessing range of motion in lumbar spine (measured in degrees) in up to 5 minutes.
- Blood pressure [ Time Frame: 1 day ]Blood pressure collected via OMRON electric blood pressure monitor, in mmHg up to 60 seconds.
- Heart Rate Variability [ Time Frame: 1 month ]Heart rate variability (LF/HF) collected via non-invasive, HRVLive! device up to 10 minutes.
- Heart Rate Variability [ Time Frame: 1 month ]Heart rate variability (BPM) collected via non-invasive, HRVLive! device up to 10 minutes.
- Heart Rate Variability [ Time Frame: 1 month ]Heart rate variability (ECG) collected via non-invasive, HRVLive! device up to 10 minutes.
