Post-traumatic stress disorder (PTSD) is an often devastating psychiatric condition that can occur in people who experience or witness a traumatic event.The estimated lifetime prevalence of PTSD is reported to be 6.8%.While trauma-focused psychotherapy is generally the first-line treatment in PTSD management, pharmacological treatments (selective serotonin reuptake inhibitors) are recommended in second-line treatment.Additionally, various physiotherapy and rehabilitation approaches such as aerobic, respiratory, relaxation, stretching, balance and strengthening exercises can also be used.Progressive muscle relaxation training increases parasympathetic nervous system activity. This is said to reduce anxiety and stress levels and improve sleep quality, resulting in physical and mental relaxation.
