Acupuncture for knee osteoarthritis with sensitized acupoints: results from a pilot, feasibility randomized controlled trial.

ABSTRACT:

Background

Although previous clinical studies suggest possible benefits of acupuncture for knee osteoarthritis (KOA), the value of acupuncture at sensitized points is uncertain. We aimed to preliminarily assess the feasibility of performing a definitive randomized controlled trial to explore the effectiveness of acupuncture for KOA with highly sensitized acupoints.

Methods

In this randomized, single-blind, parallel, pilot trial, 36 participants with KOA were randomly assigned to receive acupuncture at highly sensitized acupoints (high-sensitization group) or at low/non-sensitized points (low/non-sensitization group) by a computer-generated random sequence. Both groups received three treatment sessions per week for four consecutive weeks (12 sessions in total). Assessments were performed at screening and at 4, 8, 12, and 16?weeks after randomization. Primary feasibility outcomes were patient recruitment, retention rate, and adherence to group treatment. Secondary outcomes included the change of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total score from baseline to 16?weeks, the change of Short Form (SF)-12 health survey score, and safety outcomes.

Results

Patient recruitment of 36 patients took 2 months, achieving the recruitment target. Retention rates were similar between the treatment groups, 14 (77.8%) patients in the high-sensitization group completed the 16-week follow-up and compared to 14 (77.8%) patients in low/non-sensitization group, but the result was lower than expected. All patients received at least ten treatment sessions in total. The WOMAC total score and the pain, stiffness, and physical function score in the high-sensitization group were lower or very close to those in the control group at each assessment point. Similar results were observed on quality of life. No adverse events occurred.

Conclusion

This trial has presented preliminary data on the feasibility of conducting a large trial to test the effectiveness of acupuncture at sensitized points in KOA patients.

Project description:Background Acupuncture is one of the most popular complementary and alternative treatments for knee osteoarthritis (KOA). There are many methods of acupuncture in the treatment of KOA, and the effects are different. According to our clinical observations and researches, it is found that manual acupuncture (MA), electro-acupuncture (EA), and warm acupuncture (WA) are used more frequently in the treatment of KOA, and the curative effects are satisfactory. However, there is currently a lack of efficacy comparison of efficacy between different acupuncture treatments, as well as a lack of standardized clinical research on the acupuncture treatment of KOA. Therefore, we will carry out a high-quality clinical randomized controlled trial to research the effect laws of MA, EA, and WA on KOA. Methods/design A total of 200 eligible participants with KOA will be randomly assigned to group A, B, C, or D in a ratio of 1:1:1:1. Patients in group A will receive MA, while those in group B, group C, and group D will be treated with EA, WA, and sham acupuncture (SA), respectively. Patients will be treated with acupuncture once a day, 30 min per session, 5 sessions per week for 4 weeks. The primary outcome is the change of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) at week 4. The secondary outcomes include WOMAC, visual analog scale (VAS), Arthritis Quality of Life Measurement Scale Simplified Scale (AIMS2-SF), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), and Credibility/Expectancy Questionnaire. The evaluation will be performed at baseline and weeks 4, 8, and 12 respectively after randomization. Discussion This is a randomized controlled trial. We will observe the clinical effect of MA, EA, and WA on KOA to research the effect laws of these three acupuncture treatments on KOA and set up standardized treatment programs for acupuncture for KOA.

Project description:Little is known about the relationships of circulating levels of biomarkers of cartilage degradation with biomechanical outcomes relevant to knee osteoarthritis (OA) or biomarker changes following non-pharmacological interventions. The objectives of this exploratory, pilot study were to: 1) examine relationships between biomarkers of articular cartilage degradation and synthesis with measures of knee joint load during walking, and 2) examine changes in these biomarkers following 10 weeks of strengthening exercises.Seventeen (8 male, 9 female; 66.1 +/- 11.3 years of age) individuals with radiographically-confirmed medial tibiofemoral OA participated. All participants underwent a baseline testing session where serum and urine samples were collected, followed by a three-dimensional motion analysis. Motion analysis was used to calculate the external knee adduction moment (KAM) peak value and impulse. Following baseline testing, participants were randomized to either 10 weeks of: 1) physiotherapist-supervised lower limb muscle strengthening exercises, or 2) no exercises (control). Identical follow-up testing was conducted 11 weeks after baseline. Biomarkers included: urinary C-telopeptide of type II collagen (uCTX-II) and type II collagen cleavage neoepitope (uC2C), serum cartilage oligomeric matrix protein (sCOMP), serum hyaluronic acid (sHA) and serum C-propeptide of type II procollagen (sCPII). Linear regression analysis was used to examine relationships between measures of the KAM and biomarker concentrations as baseline, as well as between-group differences following the intervention.KAM impulse predicted significant variation in uCTX-II levels at baseline (p?=?0.04), though not when controlling for disease severity and walking speed (p?=?0.33). KAM impulse explained significant variation in the ratio uCTX-II;sCPII even when controlling for additional variables (p?=?0.04). Following the intervention, changes in sCOMP were significantly greater in the exercise group compared to controls (p?=?0.04). On average those in the control group experienced a slight increase in sCOMP and uCTX-II, while those in the exercise group experienced a reduction. No other significant findings were observed.This research provides initial evidence of a potential relationship between uCTX-II and knee joint load measures in patients with medial tibiofemoral knee OA. However, this relationship became non-significant after controlling for disease severity and walking speed, suggesting further research is necessary. It also appears that sCOMP is amenable to change following a strengthening intervention, suggesting a potential beneficial role of exercise on cartilage structure.Clinicaltrials.gov NCT01241812.
