Retrospective Study on Safety of Acupuncture Treatments for Chronic Low Back Pain in 65 Years and Older in an Acupuncture Clinic From 2013 to 2018.

Acupuncture, along with other complementary and integrative treatments, is commonly used as a
complementary or integrative therapy when treating a multitude of pain complaints, including
chronic low back pain(CLBP). It has been practiced as a non-pharmacological therapy in the
United States over one hundred years. Integrative pain management pilot programs have
demonstrated impressive reductions in medications use, emergency room visits, and annual
costs of healthcare. In fact, CLBP is one of the most common conditions treated in an
acupuncturist's daily schedule. Based on acupuncturists' practice, CLBP has accounted for
about 12% of patient visits in recent years. Most CLBP patients who come to acupuncturists'
clinic are older adults. Investigators will retrospectively check the safety of acupuncture,
i.e.side effects or adverse effects of acupuncture during treatments of CLBP in older adults
in past 5 years.

Back pain, especially low back pain (LBP), is one of the most common conditions for Americans
to visit their physicians and therapists. In a recent survey, chronic neck and/or back pain
was found to affect 54% of American adults in 2017. Another survey found that 32.5% of those
65 years and older suffer from back pain. Chronic low-back pain (CLBP) is defined by National
Institutes of Health (NIH) as pain at the low back that persists for 12 weeks (3 months) or
longer, even after an initial injury or underlying cause of acute low-back pain has been
treated. About 20% of people affected by acute low-back pain develop CLBP with persistent
symptoms at 1 year.

The inclusion criteria of CLBP in older adults:

Age: 65-80 years old. CLBP is defined as a back pain problem that has persisted for at least
3 months or has resulted in pain on at least half the days in the past 6 months. A minimum
pain intensity score of 4 out of 10 on a visual analog scale (0 = no pain, 10 = most severe
pain); ability of the participant to fully understand the trial procedure and the risks
involved, communicate with the examiner, and comply with the protocol; provision of written
informed consent for participation.

The exclusion criteria of CLBP in older adults:

Age: younger than 65. Pain mainly at legs; a history of spinal surgery; hip osteoarthritis;
progressive neurological deficit or severe psychiatric or psychological disorders; serious
spinal disorders, such as metastatic cancer, vertebral fracture, spinal infection, and
inflammatory spondylitis; other contraindications for treatment, such as clotting disorders,
use of anticoagulants or chemotherapy medications, and seizure disorders; presence of a
device that could be affected by electromagnetic fields, such as a pacemaker; use of
medications that could affect the trial results, such as corticosteroids and anticonvulsants,
within the last week; participation in other clinical trials; ineligibility judged by a
researcher.

For acupuncture in CLBP in older adults, one of public concerns is the safety of acupuncture.
A thorough systematic review by Chan, et al. published in 2017 concludes that while some
adverse events are reported, "all the reviews have suggested that adverse events are rare and
often minor." These findings are consistent with prior studies. Some severe adverse events
such as brain stem piercing, spinal lesions, infectious disease transmission, organ puncture,
needle breaking and migrating, and death have been documented in other countries, but may be
associated with provider competence and training, and could be avoided with sufficient
regulations determining appropriate clinicians. Most of such severe adverse events are not
within the scope related to the treatment in CLBP. There is no any specific acupuncture
safety observation in treating CLBP in seniors. The aim of current study is retrospectively
check all information documented related to side effects or adverse effects of acupuncture
during treatments of CLBP in older adults in past 5 years. The treatments of acupuncture for
CLBP are:

1. Acupuncture points (acupoints) or locations Use local points, in or near pain area, plus
distant points. The local acupoints include Shenshu (BL23), Qihaishu (BL24), Dachangshu
(BL25), and Guanyuanshu (BL26). These four pairs of points are located beside the L2-L5
spinal nerve foramen, while the CLBP may be related to L3-L5 nerves, erector spinae and
associated fascia. Also use Yaoyan (EX-B-7). If the pain point (also called "tender
point," "Ashi point" or "trigger point") is not located exactly at a traditional point
location, consider the use of the tender point, instead of traditional point locations.
If there are pain points (Ashi or trigger points) at gluteal muscles or the sacroiliac
joint, add local points there as well. In clinical practice, 8-10 needles are used for
these acupoints. The distant acupoints include Zusanli (ST36), Weizhong (BL40),
Yanglingquan (GB34), Fengshi (GB31), and Sanyinjiao (SP6). I use up to 3 pairs of distal
acupoints.

2. Needle sizes and needling technique Use 1.5-2.0 cun (40-50 mm), 30 or 32 gauge (G; 0.30
or 0.25 mm in diameter) filiform acupuncture needles. Occasionally, use 3.0 cun (75 mm),
G30 needles for the gluteal muscle area (Cloud & Dragon, LEKON or EXPERT Traditional Acu
Needles, manufactured and distributed by C.A.I. Corporation, USA). Prefer to treat
patients in the prone position, inserting needles vertically (or slightly obliquely to
the spinal foramen) about 1-1.5 cun (40-50 mm) deep, depending on patient size.

3. Inducing Deqi or not Use light Deqi technique [11]. That is, after inserting the
needles, patients will feel some pressure or soreness at the local soft tissue area; at
the same time, the acupuncturist will feel a pulling or pressure sensation from the
inserted needle. Generally, do not use electric acupuncture for older adults with CLBP,
due to the fact that such patients may have deficiency conditions. But use an infrared
lamp to treat the low-back area during the acupuncture session. The acupuncture
treatment lasts 45 min. After that, use light- to moderate-force suction cupping at the
low-back pain area for 3-5 min.

4. Treatment duration Ideal treatment frequency or duration is 16-24 sessions: twice a week
for 8-10 weeks, then once a week for 4 weeks, if possible. Most senior patients only
have Medicare insurance, and in some cases, supplemental insurance; Medicare and
supplemental insurance generally do not cover acupuncture. In the real world, senior
CLBP patients have to pay out-of-pocket (give them some discount). Senior patients with
CLBP may only choose to pay for 8-10 sessions, which may limit acupuncture's
effectiveness.

One characteristic of CLBP in senior patients is that it may be due to a deficiency condition
("kidney deficiency" or "qi-blood deficiency"), which makes CLBP in seniors more difficult to
treat than in younger adults. For this reason, one strategy of mine is using tonifying or
strengthening acupoints: BL23, ST36, SP6, etc. Another strategy is to encourage patients to
get more acupuncture sessions, such as 16-20 sessions, or say, after extensive treatments,
then to get some tuning up sessions. In current investigator's practice, add Shenting (GV24),
Yintang or ear Shenmen to calm patients' spirit, and help get a quicker effect in treating
the older adults'CLBP.

In the United States, there has been no large-scaled acupuncture clinical trial of CLBP in
older adults, especially focused on the real-world practice, therefore, there was no any
safety evaluation study of acupuncture during the treatments of CLBP in older adults. In
current studies, the investigators will check the CLBP senior (>65 years old) patients' files
in past 5 years and find the detail safety information, i.e.side effects or adverse effects.
