Vibration Therapy in Orthopaedic Rehabilitation Evaluation of in-Patient Rehabilitation Measures in Orthopaedic Patients Using a Mechanical Vibration Couch

Purpose Clinical uses of mechanical whole body vibration therapies are the subject of contradictory debate. Orthopaedic pathologies, including the presence of endoprostheses, are considered to be contraindications. Materials and Methods Within the context of a 3-week in-patient rehabilitation programme 109 orthopaedic patients (61,48 years) were stratified to one of the trial groups: vibration therapy couch (Tiktaalik), dry water massage (Hydrojet) and sham treatment (placebo). Effects on the quality of medical results and heart rate variability were examined. Results The therapy had a duration of 12min. The vibration frequency of the treatment couch was self-selectable between 11 and 15Hz in the chest region and 3 and 7Hz in the pelvic region. Two patients had to stop the vibration therapy early (headaches, dizziness). The rehabilitation measures allowed mobilisation, leading to increased activation of the sympathetic nervous system. Improvements in pain perception (VAS) and motor function (flexibility, muscle strength) were identified during the course of the rehabilitation. An interaction of the rehabilitation process with the trial groups was observed immediately after each unit of therapy: The flexibility, muscle strength and alertness improved more markedly in the Tiktaalik group. At the same time the mechanical vibration therapy distinguished itself particularly by more marked parasympathetic modulation - there was significantly greater relaxation in the post-treatment rest phase. Discussion and Conclusions The study results show that mechanical vibration therapy represents an addition to the currently available treatment options for orthopaedic rehabilitation.
