Comparative study on curative effect and recurrence rate of chronic scapulohumeral periarthritis treated with different acupuncture techniques

OBJECTIVES

To observe the effects of the local stimulation with 3 acupuncture techniques, i.e. Canggui Tanxue (needle insertion method like dark tortoise detecting point) technique, electroacupuncture (EA) and warm needling (WN) with filiform needles on shoulder pain, shoulder joint function, quality of life, inflammatory indicators and recurrence rate in the patients with chronic scapulohumeral periarthritis (CSP), so as to explore the optimal needling method of acupuncture for the predominant symptoms of CSP during the attack stage in the patients.

METHODS

A total of 108 patients with CSP were randomly divided into a manual acupuncture (MA) group (36 cases, one case dropped off), a WN group (36 cases, 3 cases dropped off) and an EA group (36 cases, 1 case dropped off). In the three groups, Jianqian (EX-UE12), Jianyu (LI15), Jianzhen (SI9), Ashi (Extra) and Yanglingquan (GB34) on the affected side were selected. Canggui Tanxue needling technique, WN technique and EA were delivered in the MA group, the WN group and the EA group, respectively, 30 min each time, 3 times weekly for 4 weeks. The Neer test scores were compared；the visual analogue scale (VAS) was used to assess the degree of shoulder joint pain；the daily life activity abilities was evaluated using the activities of daily living (ADL) scale；the serum prostaglandin E2 (PGE2) content was measured using ELISA before and after treatment. The effectiveness rate and recurrence rate were calculated, and the occurrences of adverse reactions were recorded.

RESULTS

Compared with the scores before treatment, the scores of pain, joint function, and range of motion as well as the total score of Neer test were all increased after treatment in the three groups (P<0.05)；the VAS score, ADL score and the content of serum PGE2 were decreased (P<0.05). After treatment, the pain score of Neer test in the EA group and the WN group were higher than those of the MA group (P<0.05), the joint function score of Neer test in the MA group and the WN group were higher than that of the EA group (P<0.05), and the range of motion score of Neer test in the MA group was higher when compared with the EA and WN groups (P<0.05). There was no statistical difference in the total score of Neer score among the three groups. VAS score in the EA group was lower than that of either the WN group or the MA group (P<0.05). ADL score in the MA group was lower compared with that of the WN group (P<0.05). PGE2 levels in both the WN group and the MA group were lower than that of the EA group (P<0.05). The total effective rate was 85.71% (30/35) in the MA group, 91.43% (32/35) in the EA group and 90.91% (30/33) in the WN group, there was no statistical differences among the three groups. At the end of the 6-month follow-up visit after treatment, there was no significant difference in the recurrence rate among three groups. No serious adverse reaction was found.

CONCLUSIONS

In the treatment of CSP, the short-term effect is equivalent among EA, WN and MA. But, the analgesic effect is the best in the EA group, the treatment for anti-inflammation is the most effective in the MA and WN groups, and the needling technique of Canggui Tanxue in the MA group obtains the most favorable effect of releasing adhesion and recovering the range of motion in the shoulder joint.

[An anti-scald device for warm needling]

Warm needling, i.e. acupuncture with the needle warmed by burning moxa stick or cone, is frequently employed in the treatment of cold and dampness type disorders. During treatment, accidental skin scald may occur if the burning moxa drops on the skin due to slight changes in patient's body position. Thus, we designed and developed an anti-scald device for warm needling which is suitable for any part of the body. This device is made up of two parts, a stainless steel-grid moxa cartridge (including half cylinder, hinge shaft, lug, limit bar, clamping arm, connecting arm, torsion spring, heat insulation pad, through holes) and a clamp holder which is in an integrated structure. The grid moxa cartridge can be used to wrap the burning mugwort cone in all directions to prevent the ignited moxa-cone from falling and skin scalding, and effectively collect the burned moxa ash. At the same time, the clamp holder can be used to help fix the moxa-cone to increase the stability of warm needling operation. The device is convenient to operate and novel in design, can effectively reduce the occurrence of scald accidents in clinical treatment, save time and manpower, and has both economic and ecological benefits, being helpful to the promotion and use of warm needling.

[Clinical observation of acupotomy combined with warm needling for cervical spondylotic radiculopathy of qi and blood stagnation syndrome]

OBJECTIVE

To observe the clinical effect of acupotomy combined with warm needling on cervical spondylotic radiculopathy (CSR) of qi and blood stagnation syndrome.

METHODS

A total of 90 CSR patients were randomly divided into an acupotomy group, a warm needling group and a combined treatment group, with 30 cases in each group. The patients in the acupotomy group were treated with acupotomy, once every 7 days, consecutively for 3 times. The patients in the warm needling group received warm needling, once daily, at the interval of 2 days after consecutive treatments for 5 days, 7 days as one session of treatment and 3 consecutive sessions were required. The patients in the combined treatment group were treated with acupotomy and warm needling, and the methods and the treatment session were same as the the previous two groups. Before and after the treatment, the pain rating index (PRI) of McGill pain questionnaire (MPQ) and the 20-point scale of CSR developed by Yasuhisa Tanaka (CSR20) were adopted in the assessment. The changes of clinical symptoms and functions of patients were observed and the clinical efficacy was assessed in each group.

RESULTS

After the treatment, the PRI score was decreased (P<0.05) and the CSR20 score was increased (P<0.05) in the 3 treatment groups when compared with those before the treatment. After the treatment, compared with the acupotomy group and the warm needling group, the PRI score was decreased (P<0.05) and the CSR20 score was increased (P<0.05) in the combined treatment group. The total effective rate was 83.3% (25/30) in the acupotomy group, 76.7% (23/30) in the warm needling group and 93.3% (28/30) in the combined treatment group. The total effective rate in the combined treatment group was higher than those in the acupotomy group and the warm needling group (P<0.05).

CONCLUSION

The combined treatment with acupotomy and warm needling may obviously improve the clinical symptoms and physical signs, e.g. pain and numbness in the patients with CSR of qi and blood stagnation syndrome. Its efficacy is remarkably higher than that of the simple application of acupotomy or warm needling.

[Effect of balance acupotomy combined with warm needling in treatment of cervical spondylosis of vertebral artery type]

OBJECTIVE

To observe the clinical efficacy of balance acupotomy combined with warm needling in treatment of cervical spondylopathy of vertebral artery type (CSA).

METHODS

Ninety patients were randomly divided into a warm needling group, a balance acupotomy group and a combined treatment group, 30 cases in each one. In the warm needling group, warm needling was given, once daily, for 5 days consecutively, with the interval of 2 days every week, and the treatment was conducted for 3 weeks. In the combined treatment group, on the base of the treatment as the warm needling group, the balance acupotomy was exerted, for consecutive 3 weeks. In the balance acupotomy group, the balance acupotomy was adopted, once a week, for 3 weeks consecutively. Clinical efficacy, the mean blood flow velocity of left vertebral artery (LVA), right vertebral artery (RVA) and basilar artery (BA), the pulse index (PI) and the resistance index (RI) were observed in 3 groups separately. The score of vertigo symptom and function was compared before and after treatment in 3 groups.

RESULTS

In comparison with before treatment, the score of evaluation scale for cervical vertigo (ESCV) and the mean blood flow velocity of LVA, RVA and BA were all increased (P<0.05). while PI and RI reduced (P<0.05) in each group after treatment. In comparison with those in the warm needling group and the balance acupotomy group, ESCV score and the mean blood flow velocity of LVA, RVA and BA were increased (P<0.05), while PI and RI decreased (P<0.05) in the combined treatment group after treatment. Compared with the balance acupotomy group, the mean blood flow velocity of LVA, RVA and BA was increased (P<0.05), and PI and RI reduced (P<0.05) in the warm needling group after treatment. The total effective rate was 73.3% (22/30) in the warm needling group, 70.0% (21/30) in the balance acupotomy group and 93.3% (28/30) in the combined treatment group respectively. The total effective rate in the combined treatment group was higher than that either in the warm needling group or in the balance acupotomy group (P<0.05).

CONCLUSION

Balance acupotomy combined with warm needling may restore the mechanical equilibrium state of the neck, and effectively improve the change of vertebral-basilar artery blood flow and relieve vertigo symptoms in patient with of cervical spondylosis of vertebral artery type.

Efficacy and safety of electroacupuncture plus warm needling therapy for heel pain: study protocol for a randomized controlled trial

Background

Heel pain is a common foot disorder that causes pain and functional limitations. The prevalence of disabling foot pain will increase as the population ages. Previous studies have reported the positive therapeutic effects of electroacupuncture, warm needling, or the combination of both for heel pain but with limitations in the study methodologies. The current study is a rigorously designed randomized controlled trial that aims to evaluate the clinical efficacy and safety of electroacupuncture plus warm needling therapy in patients with heel pain.

Methods/design

The study protocol describes a prospective, open-label, parallel-group, randomized controlled trial to be conducted in Hong Kong. Eighty patients aged 50–80 years who have reported heel pain and first-step pain equal to or exceeding 50 mm on the 100-mm visual analog scale (VAS) will be recruited. They will be randomly assigned (1:1 ratio) to the electroacupuncture plus warm needling therapy (i.e., treatment) group or the waitlist (i.e., control) group. The treatment group will undergo six treatment sessions in 4 weeks. The control group will receive no treatment during the study period. The primary outcome measure is a mean change in the first-step pain VAS score from the baseline to week 4. Secondary outcome measures include a mean change in first-step pain VAS score from the baseline to week 2, a mean change in Foot Function Index (FFI) subscale scores and the total score from the baseline to week 2 and week 4, and patients’ self-reported level of improvement at week 4. Additional week 8 follow-up assessments with first-step pain VAS and FFI measurements will be arranged for the treatment group. Any adverse events will be recorded throughout the study to evaluate safety. An intention-to-treat approach will be used to analyze the study results.

Discussion

This study will provide evidence on the efficacy and safety of electroacupuncture plus warm needling therapy as an alternative treatment method for heel pain. The findings will determine whether the treatment protocol is efficacious in relieving pain and improving foot function among older adults with heel pain. The study will also provide information for subsequent large-scale randomized controlled trials in the future.

Efficacy and safety of using a warming needle for persistent allergic rhinitis: study protocol for a randomized controlled trial

Background

Many previous studies have shown the potential therapeutic effect of acupuncture for allergic rhinitis. Most of these studies, however, were limited by the short duration of observations and lack of sham acupuncture as the control group. Our preliminary experiments showed that the use of a warm needling achieved a much more persistent effect in the treatment of allergic rhinitis (AR) compared with simple acupuncture therapy. Hence, we have designed a multicenter, randomized controlled trial (RCT) in which the first-line medication loratadine will be used as the control group, and the effect of warm needling therapy will be evaluated through long-term observation.

Methods/design

The trial is designed as a multicenter, parallel-group, randomized, single-blinded (outcome assessors), non-inferiority trial. A total of 98 patients with persistent AR will be randomly assigned into two groups. Patients in the treatment group will be treated with warm needling at GV14 and acupuncture at EX-HN3, ST2, LI20, EX-HN8, GV23, LU7, LU5 and LI4 three times a week, for a total of 4 weeks. Patients in the control group will be treated with oral loratadine 10 mg/day for 4 weeks. The primary outcome will be the change in the Total Nasal Symptom Score (TNSS) from baseline to that at 6 months after treatment during the follow-up period. The secondary outcomes will include the Total Non-nasal Symptom Score and the Rhinoconjunctivitis Quality of Life Questionnaire, changes in the TNSS from baseline to that at 2 and 4 weeks during treatment, and 3 months after treatment during the follow-up period. Outcomes will be measured at 2 and 4 weeks, and 3 and 6 months after treatment. Any side effects of treatment will be observed and recorded.

Discussion

We expect that the study results will provide evidence to determine the effects of warm needling compared with loratadine. Our final goal of the study is to evaluate the difference in the short-term and long-term effects between the two therapeutic methods, especially the long-term effect of warm needling.
