Electroacupuncture Treatment for Those With End Stage Knee Osteoarthritis on a Total Knee Arthroplasty Waitlist
- Conditions
- Knee Osteoarthritis
- Interventions
- Other: Electroacupuncture
- Registration Number
- NCT05374330
- Lead Sponsor
- University of Manitoba
- Brief Summary
A 3-armed pilot randomized controlled trial: electroacupuncture, sham acupuncture and waitlist groups.
- Detailed Description
The purpose of this study is to determine the efficacy of EA as a treatment strategy in the end stage knee osteoarthritis (KOA) population waiting for total knee arthroplasty (TKA). The research objectives are to 1. To determine the efficacy of EA to provide pain relief, improve function and quality of life in the end stage KOA population who are waiting for TKA. 2. To determine if EA is superior to sham EA or waiting list groups in providing pain relief, improving function and quality of life in the end stage KOA population who are waiting for TKA.
Outcome measures will be collected from all 3 groups at baseline, mid point, completion and 6 week follow up.
Participants will be recruited from the Concordia Joint Replacement Group in Winnipeg, Manitoba.
Inclusion Criteria: participants are on a waiting list for TKA and do not have a surgical date within 3 months from the start of the study.Waiting list will be defined as having had consultation with an orthopaedic surgeon and having accepted an offer a TKA. The participants will be a minimum of 45 years old and have a NPRS ≥ 5.
Exclusion Criteria: knee pain caused by other disease or injury, arthroscopy within the past year, intra articular injection within the previous 3 months, painful ipsilateral hip OA. Participants scheduled for simultaneous bilateral TKA or revision will be excluded.
Medical history: serious acute or chronic disease or psychiatric disorders, blood coagulation disorders.
Surgical history: implanted cardiac pacemakers, history of valve replacement, previous arthroplasty.
Other: allergy to needle components, needle phobia, pregnancy

Group Intervention Description Electroacupuncture Electroacupuncture Acupuncture needles will be inserted into the body at standardized acupuncture points. Electrical current will then be applied using 2 channels of electrical current for a total of 4 points receiving electroacupuncture Sham acupuncture Electroacupuncture Sham Acupuncture needles will be placed at standardized acupuncture points. Sham electrical current will then be applied using 2 channels / 4 points as in the electroacupuncture group. The electrical current will not be turned on.
- Primary Outcome Measures
Name Time Method The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Baseline, 3 weeks, 6 weeks and 6 weeks after study completion Disease specific outcome measure. Measuring change in disease specific function over 4 time points (as noted below). The WOMAC provides a multidimensional assessment inclusive of activities of daily life (ADL's), functional mobility, gait, general health, and quality of life organized into 3 subscales (pain, stiffness, physical function) consisting of 24 items scored on a 5-point scale from 0-4. Higher scores represent higher pain values or worse function for a total possible score of 96.
- Secondary Outcome Measures
Name Time Method Numeric Pain Rating Scale (NPRS) Baseline, 3 weeks, 6 weeks and 6 weeks after study completion Pain outcome measure: measuring change in pain over 4 time points (as noted below). The NPRS measures pain on a 0-10 point scale with 0 being no pain and 10 being the most severe pain.
The Short Form McGill Pain Questionnaire (SF-MPQ) Baseline, 2 weeks, 6 weeks, and 6 weeks after study completion Pain outcome measure. measuring change in pain over 4 time points (as noted below). Using a 5-point pain intensity scale, there are 4 subscales with a total of 78 pain descriptor items and a single item pain intensity scale.
The Short Form-Survey 36 (SF-36) Baseline, 3 weeks, 6 weeks and 6 weeks after study completion Quality of life outcome measure. Measuring change in health related QOL over 4 time points (as noted below). The SF-36 includes 36 items which cover 8 health domains: limitations in physical activities because of health problems, limitations in social activities because of physical or emotional problems, limitations in usual role activities because of physical health problems, bodily pain, general mental health, limitations in usual role activities because of emotional problems, vitality, and general health perceptions. A total score can be used to indicate low or high HRQoL, while the physical component summary and the mental component summary can be used to rate these 2 separate dimensions of HRQoL.
