Influence of a vibrating therapeutic couch on pain level in healthy adults with back pain

INTERVENTION: The treatment was carried out on a Spintrac couch from the manufacturer Kurperle GmbH, Bad Füssing. The treatment time was 10 minutes. The therapy was carried out according to the manufacturer's operating instructions. Participants will be randomly assigned to either an infrared/heat group (heat group), a vibration group (VIB group) or a combination group (COMBI group) using a simple randomisation method. In the infrared/heat group, the therapy is carried out using only the heat generated under infrared light (near‐infrared range) with a wavelength of 780‐1000 nm. In the vibration group, the therapy takes place only by means of vibration (clockwise rotating horizontal oscillation with a frequency of 20 Hz and an oscillation of 1 cm). In the combination group, the therapy is carried out in a combination of the previously described intervention using infrared light and the previously described clockwise horizontal vibration. Blinding was not possible, so this is an open‐label intervention. CONDITION: Decreasing low back pain in healthy adults ; Musculoskeletal Diseases PRIMARY OUTCOME: Pain measured using a visual analogue scale (VAS) at baseline, post‐intervention, and 24h post‐intervention SECONDARY OUTCOME: 1. Blood oxygen saturation measured using a pulse oximeter at baseline and post‐intervention; 2. Blood perfusion inde Xmeasured using a pulse oximeter at baseline and post‐intervention INCLUSION CRITERIA: 1. People between the ages of 18 and 80 years old 2. Non‐specific back pain in the last 24 hours determined using the VAS scale 3. Greater than 30 mm and less than 90 mm (pain at rest and/or on movement) on the VAS scale at randomization 4. Written informed consent dated and signed by the patient
