Achieving health, well-being, and participation in life through engagement in occupation is the statement that describes the domain and process of occupational therapy in its fullest sense. This definition includes all areas of influence in occupational therapy: type of employment (level of active lifestyle: rest and sleep, education, work, pleasure, social participation), client factors (values, beliefs, spirituality, body functions and structures), skill performance (motor, process and social interaction skills), pattern performance (habits, routines, rituals, roles), environment (cultural, personal, physical, social, virtual). Occupational therapy in military service is difficult in its own way. The main feature is that veterans demand constant monitoring and support. These people are vulnerable to suicide. That’s why occupational therapist should not wait for their self-referral. Members of soldier’s family need to be actively involved in cooperation as well. Practical guidelines of colleagues from the Canadian Association of Occupational Therapists “Working for the Canadian Armed Forces and Veterans Affairs Canada” and “A Guidance Document for Occupational Therapists” are most suitable for the implementation in Ukrainian realities. Occupational therapy process starts with an assessment of functioning and disability in relation to a health condition. In Ukraine, an analogue of the International Classification of Functioning, Disability and Health (Order of the Ministry of Health of Ukraine dated 23.05.2018 No. 981) has been identified and introduced, which allows for a comprehensive functional assessment and further steps of planning, monitoring compliance, evaluation of occupational therapy. Primary screening is significantly facilitated by a test system developed by colleagues from different countries, which requires translation into Ukrainian and implementation. It would be appropriate to use a single base of servicemen for their distribution according to the priority of providing care that would optimize the start of occupational therapy. It is necessary to study in detail the long-term experience and advances of developed countries and integrate the promising experience of colleagues in military occupational therapy in Ukraine, which has a chance to become one of the promising specialties with a high level of military service.
