Investigation of Single Session Action Observation and Motor Imagery Training on Balance, Muscle Oxygenation, Fatigue

Plain-language summary

Action observation (AO) and motor imagery (MI) interventions are frequently employed both in the rehabilitation process following orthopedic injuries and surgeries, with aims such as reducing pain and increasing joint range of motion, as well as in the rehabilitation of neurological disorders to restore motor functions and achieve functional independence. In recent years, it has been demonstrated that AO and MI training can exert positive effects on motor performance and neurophysiological activation. Notably, when AO and MI training are applied in combination, it has been suggested that they produce a more pronounced impact on motor performance and support motor learning processes. The effects of these techniques have generally been evaluated following long-term interventions, and there is limited data in the literature regarding their effects after a single session. Furthermore, it has been shown in the literature that action observation and motor imagery training can elicit cortical activation. However, current scientific evidence concerning the peripheral effects of these interventions remains limited. Therefore, the aim of the present study is to investigate the acute effects of a single session of action observation and motor imagery training on upper extremity balance, muscle oxygenation, and fatigue in asymptomatic young adult males
