Effect of osteopathic manipulative treatment on interoceptive accuracy and sensibility in healthy subjects and patients with chronic low back pain: A randomised controlled trial

This project reports a single-blinded, parallel-group, multi-center, randomised controlled trial investigating the effect of osteopathic manipulative treatment, compared to sham treatment, on the interoceptive accuracy and sensibility, pain intensity and disability, and heart rate variability in healthy subjects and patients with chronic low back pain. The dataset contains anonymized data from 68 adult participants (including six drop-outs), comprising 34 healthy subjects (including one drop-out) and 34 patients with chronic low back pain (including five drop-outs), collected in 2024. The dataset includes sociodemographic and clinical variables, individual group allocation (osteopathic [OMT] vs. sham [SHAM] treatment), adverse events and blinding concealment rates, and outcome data for an interoceptive accuracy task (Heartbeat Counting Task [HCT]), self-report questionnaires for interoceptive sensibility (Multidimensional Assessment of Interoceptive Awareness 2 [MAIA-2]) and pain-related disability (Oswestry Disability Index [ODI]), a scale for pain intensity (Numeric Rating Scale [NRS]), and heart rate variability data (HRV) (Electrocardiogram [ECG]). Furthermore, the raw data underpinning the HCT have been added (i.e., reported and recorded heartbeats per participant, time interval, and time point). Data were collected using paper forms, except for ECG data, which was recorded electronically. The dataset may be reused for secondary analyses.
