Movement quality is a phenomenon frequently used by physiotherapists in oral language, written text, and clinical practice, with little clarification. The purpose was to investigate the lived experiences of a group of expert physiotherapists, searching for essential features and characteristics of the phenomenon. A phenomenological study, using in-depth interviews was chosen. Ten copies of Fine Art were used to stimulate the description of the phenomenon. The informants were 15 peer-designated physiotherapists, five from each field of neurology, psychosomatic/psychiatry and primary health care. They were nominated by physical therapist leaders in the region. The interviews were audiotaped and transcribed. Giorgis' recommendation concerning analysis of the interview data was followed. Four main themes were developed, seeing movement quality as biomechanical, physiological, psycho-socio-cultural, and existential, all interacting processes. Each theme includes preconditions to movement quality and movement characteristics. Movement quality in general was seen as a unifying phenomenon, representing a synthesis of the four themes. The outcome of the study is the Movement Quality Model (MQM) illuminating essential features and characteristics of the phenomenon. Further research is needed for clarification and application in clinical practice
