Other | Participants' expectations for acupuncture at baseline. | At baseline, participants in both groups will be asked to answer the following question: "What do you expect from EA treatment to improve your hand OA?" | baseline | |
Other | Blinding assessment | All participants will be told before allocation that insertion is deeper in group A (traditional acupuncture) and shallower in group B (modern acupuncture). After treatments finished, they will be asked "Do you think you were in group A (traditional acupuncture) in the past weeks?", the answers are "Yes", "No" or "Unclear". | immediately after the intervention | |
Other | Self-reported consumption of acetaminophen for hand OA. | The proportion of participants using acetaminophen, and the frequency and total dosage of acetaminophen used will be calculated and assessed. | during weeks 1-4, weeks 5-8 and weeks 9-16 | |
Other | Safety assessment | Any acupuncture-associated adverse event (AE) such as dizziness, palpitations, local hematomas, or infection, and any other AE irrelevant to acupuncture, will be carefully documented. | during weeks 1-4, weeks 5-8 and weeks 9-16 | |
Primary | The proportion of responders according to the Outcome Measures in Rheumatological Clinical Trials (OMERACT) and Osteoarthritis Research Society International (OARSI) responder criteria. | Participants that meet at least one of the following criteria are considered as responders: 1) at least a 50% decrease and change from baseline=20 in VAS score; 2) at least a 50% decrease and change from baseline=20 in Australian Canadian Osteoarthritis Hand Index (AUSCAN); 3) at least a 20% decrease and change from baseline=10 in at least two measurements of VAS score, AUSCAN and global assessment. | week 5 | |
Secondary | The proportion of responders according to the Outcome Measures in Rheumatological Clinical Trials (OMERACT) and Osteoarthritis Research Society International (OARSI) responder criteria. | Participants that meet at least one of the following criteria are considered as responders: 1) at least a 50% decrease and change from baseline=20 in VAS score; 2) at least a 50% decrease and change from baseline=20 in Australian Canadian Osteoarthritis Hand Index (AUSCAN); 3) at least a 20% decrease and change from baseline=10 in at least two measurements of VAS score, AUSCAN and global assessment. | week 8 and week 16 | |
Secondary | Change in average overall finger joints pain intensity in the dominant hand over the past 48h from baseline. | Pain intensity will be measured using a 0-100 VAS, with 0 indicating no pain and 100 indicating maximal pain. | week 5, week 8 and week 16 | |
Secondary | Change in maximal overall finger joints pain intensity in the dominant hand over the past 48h from baseline. | Pain intensity will be measured using a 0-100 VAS, with 0 indicating no pain and 100 indicating maximal pain. | week 5, week 8 and week 16 | |
Secondary | The proportion of participants achieving at least a 15-point reduction in average overall finger joints pain intensity in the dominant hand from baseline | Pain intensity will be measured using a 0-100 VAS, with 0 indicating no pain and 100 indicating maximal pain. | week 5, week 8 and week 16 | |
Secondary | Change in Australian Canadian Osteoarthritis Hand Index (AUSCAN) total score, and pain, stiffness and physical function subscales from baseline. | The AUSCAN index contains a 15-item scale referring to hand pain (5 items), stiffness (1 item), and function (9 items) during the preceding 48 hours, which is valid, reliable and responsive in patients with hand OA. All items are scaled on a 0-100 VAS (0=none to 100= very severe), with higher scores indicating more severe symptoms/function. | week 5, week 8 and week 16 | |
Secondary | Change in Functional Index for HOA (FIHOA) from baseline. | The FIHOA is a patient-reported hand function questionnaire, comprising 10 items with a four-point Likert scale, in which 0 represents "possible without difficulty", 1 indicates "possible with slight difficulty", 2 represents "possible with important difficulty" and 3 indicates "impossible". | week 5, week 8 and week 16 | |
Secondary | Change in the number of self-reported painful joints and painful joints at digital pressure from baseline. | All finger joints will be reported spontaneously for the presence of pain by the participants, and examined by a trained research nurse for the presence of pain at digital pressure. | week 5, week 8 and week 16 | |
Secondary | Change in the number of swollen joints from baseline. | All soft swollen finger joints count (0-30) will be assessed by a trained research nurse at each study visit. | week 5, week 8 and week 16 | |
Secondary | Change in hand grip strength of the fingers from baseline. | Hand grip strength of the fingers of the dominant hand will be tested using a hand dynamometer. | week 5, week 8 and week 16 | |
Secondary | Change in pinch strength of the fingers from baseline. | Hand pinch strength of the fingers of the dominant hand will be tested using a Jamar digital pinch gauge respectively. | week 5, week 8 and week 16 | |
Secondary | Change in patient global assessment of improvement from baseline. | The patients will be asked to respond to the question 'Considering all the ways your hand OA affects you, how have you been during the last 48 h?' on a self-administered 0-100 VAS (0, worst possible, to 100, best possible, in 10-point increments). | immediately after the intervention, week 8 and week 16 | |
Secondary | Change in quality of life assessed by the World Health Organization Quality of Life abbreviated version (WHOQOL-BREF) from baseline. | The WHOQOL-BREF is a 26-item self-report questionnaire rated on a 5-point Likert-type scale with four domains of QOL: physical (seven items), psychological (six items), social (three items), and environment (eight items), plus 2 items representing the general QOL. The four domain scores are scaled in a positive direction with higher scores indicating a higher quality of life. | week 5, week 8 and week 16 |
