Effects of hand-press pellet on pain and daily life of elders with chronic lower back pain: randomized controlled trial

Abstract

Background For elderly people with chronic lower back pain who need long-term management, there is a need for a nursing intervention study that is effective, is easy to perform, and applies complementary and alternative therapies to manage pain without repulsion. Hand pressure therapy is a treatment indigenous to Korea used to reduce pain and improve functions of daily life by applying acupuncture, pressure sticks, and moxibustion to parts of the hand as they relate to parts of the body. This research is to identify the effects of pellet pressed on the hand on pain and the daily lives of elders with chronic lower back pain (CLBP). Methods The hand pressed-pellet intervention period was six weeks long. Twenty-seven patients in the intervention group and twenty-four patients in the placebo control group were recruited from elderly over sixty-five who used welfare centers. In the intervention group, hand pressed-pellet therapy was conducted in eleven acupressure response zones related to CLBP, and the placebo control group was provided with similar therapy and zones, but unrelated to CLBP. The research tool measured the intensity of CLBP using the Visual Analogue Scale (VAS), the Korean Owestry Disability Index (K-ODI), which are subjective indicators, and the Compact Digital Algometer, which is an objective indicator. Result The pain intensity (VAS) measured after six weeks of hand pressed-pellet therapy showed significant difference between the two groups compared to their pain before the experiment (F = 60.522, p < .001). There was a significant difference between the two groups in the pain pressure threshold using pressure statistics (F = 8.940, p < .001), and in CLBP dysfunction evaluation index (K-ODI) after applying pressed pellet to the hand (Z = − 3.540, p < .001). Conclusion Subjective indicators were measured to verify the effect of hand pressed-pellet therapy on CLBP, and the result confirmed that the hand pressed-pellet therapy was effective in alleviating CLBP. Trial registration The study was registered retrospectively with reference number KCT0008024 on 23/12/2022.
