Surface electromyography-biofeedback (sEMG-BF) may reduce the burden of CLBP by improving physical functioning, sleep, pain catastrophizing, anxiety, and depression. This qualitative study investigated the impact of weekly EMG-BF sessions on adults with CLBP.
Twenty-six individuals with CLBP participated in telephone interviews after completing an 8-week virtual sEMG-BF intervention. Trained interviewers conducted the 10-to-15-minute semi-structured interviews to understand participants' experience with the intervention. Common themes and subthemes were identified and analyzed using MAXQDA 2022 software.
Participants were predominantly middle-aged females (M = 45, range of 19 - 66) who have had exposure to utilizing conventional therapies such as physical therapy, chiropractor, and massage for the treatment of CLBP. This study focused on participants who reported their experience of the main outcome study which included perceived reductions in CLBP symptoms, including pain and stress, and positive effects on self-awareness and sleep. Three overarching themes emerged and were further divided into subthemes: participants' involvement (virtual experience, accessibility of device, and future recommendations) perceived benefits (participants gained awareness, recommendations for future treatment, met expectations, and implementation), and desire for flexibility (obstacles and COVID-19 Impact). No adverse effects were reported by any of the participants within the study.
Both physical and psychological improvements were reported by participants following an sEMG-BF intervention. Specific implementation procedures and critical barriers were identified. In particular, the ability to receive care for CLBP during the COVID-19 pandemic was important to participants.
表面肌电图生物反馈（sEMG-BF）可能通过改善身体机能、睡眠、疼痛灾难化、焦虑和抑郁来减轻 CLBP 的负担。本定性研究调查了每周 EMG-BF 疗程对 CLBP 成人的影响。
26 名 CLBP 患者在完成 8 周虚拟 sEMG-BF 干预后接受了电话访谈。经过培训的访谈者进行了 10-15 分钟的半结构化访谈，以了解参与者对干预的体验。使用 MAXQDA 2022 软件识别和分析常见主题和子主题。
参与者主要为中年女性（M = 45 岁，范围 19-66 岁），他们曾接触过物理治疗、脊椎按摩师和按摩等传统疗法来治疗 CLBP。本研究侧重于报告主要结果研究经验的参与者，包括感知到的 CLBP 症状减轻，包括疼痛和压力，以及对自我意识和睡眠的积极影响。出现了三个总体主题，并进一步细分为子主题：参与者的参与度（虚拟体验、设备的可及性和未来建议）、感知到的益处（参与者获得了意识、对未来治疗的建议、达到预期和实施）以及对灵活性的渴望（障碍和 COVID-19 的影响）。研究中没有任何参与者报告出现不良反应。
参与者在接受 sEMG-BF 干预后报告了身体和心理的改善。确定了具体的实施程序和关键障碍。特别是，在 COVID-19 大流行期间为 CLBP 提供护理的能力对参与者很重要。
