Key Finding
Both targeted and non-targeted auricular point acupressure significantly reduced real-time pain intensity and interference with daily activities in older adults with chronic low back pain compared to education control.
Researchers studied whether auricular point acupressure (ear acupressure) could help older adults with chronic low back pain by tracking their symptoms in real-time using a smartphone app. The study involved 211 adults aged 60 and older who reported their pain levels three times daily for four weeks. Participants were divided into three groups: one received targeted ear acupressure on specific points believed to help back pain, another received non-targeted ear acupressure on different points, and a control group received education only.
Both acupressure groups experienced significant pain relief compared to the education-only group. The targeted acupressure reduced worst pain, average pain, and current pain levels, while also decreasing how much pain interfered with daily activities and enjoyment of life. Interestingly, the non-targeted acupressure also provided similar benefits, reducing pain intensity and interference with daily living. The smartphone tracking revealed that people's real-time pain reports differed from their weekly recall of pain, with immediate pain ratings often being lower but interference ratings being higher.
The study had some challenges: only 45% of participants consistently completed their smartphone entries, and older participants were less likely to keep up with the daily reporting. However, those who did participate showed strong correlations between their daily reports and weekly pain assessments.
For older adults struggling with chronic low back pain, auricular point acupressure appears to be a promising non-drug option that can reduce both pain intensity and its impact on daily life. The technique may offer a safe, self-manageable approach to pain control. To explore this treatment option, seek a qualified acupuncturist or healthcare provider trained in auricular acupressure techniques.
This secondary analysis of a 3-arm RCT evaluated ecological momentary assessment (EMA) data from 211 adults aged ≥60 with chronic low back pain randomized to targeted auricular point acupressure (T-APA, n=72), non-targeted APA (NT-APA, n=74), or education control (n=65). Participants completed smartphone-based pain assessments three times daily over 29 days during a 4-week intervention period. EMA compliance was 44.8% with 54% attrition, inversely correlated with age.
Linear mixed-effects models revealed both T-APA and NT-APA significantly reduced EMA-reported pain compared to controls. T-APA reduced worst pain (β=-0.98, P<.001), average pain (β=-0.93, P<.001), and current pain (β=-1.01, P=.006). NT-APA showed similar effects: worst pain (β=-0.74, P<.001), average pain (β=-1.02, P=.001), and current pain (β=-1.26, P=.001). Both interventions significantly reduced pain interference with enjoyment of life and daily activities. EMA measures strongly correlated with 7-day recall assessments (Spearman ρ=0.53-0.95, P<.001).
Clinical implications: APA demonstrates efficacy for chronic low back pain management in older adults, with real-time data supporting sustained symptom reduction throughout treatment.
