Technology-supported training supports the rehabilitation process by providing high-intensity, repetitive, and task-specific treatment, contributes to the recovery process, and facilitates the restoration of arm function (Bertani et al., 2017). Technology-supported rehabilitation studies for the upper extremity are performed using different devices. THERA-Trainer Tigo is used for the mobilization of individuals with limited mobility after trauma or due to any reason; it is suitable for passive movement training and active movement. Treatment with active-passive exercise devices facilitates rehabilitation with natural and rhythmic movements. It allows almost all patients, from wheelchair users to walkers, to actively participate in bicycle training during the rehabilitation process (Pazo et al., 2017). There are very few studies in the literature examining the relationship between cognitive and motor performance functions of THERA-Trainer-based exercises, and the aim of this study is to provide a preliminary idea in terms of progression to clinicians during the evaluation phase and treatment, to contribute to treatment, and to academic researchers.

Stroke is a leading cause of death and disability worldwide. It can be generally classified as ischemic stroke and hemorrhagic stroke. Ischemic stroke is defined as an infarction of the brain, spinal cord, or retina and accounts for approximately 70% of all strokes. Hemorrhagic stroke occurs as a result of intracerebral hemorrhage and subarachnoid hemorrhage (Campbell et al., 2019).Technology-assisted rehabilitation supports recovery by providing high-intensity, repetitive, and task-specific treatment, facilitating the restoration of upper limb function. Studies on technology-based rehabilitation for upper extremity recovery utilize various devices. The THERA-Trainer Tigo, for instance, is designed to mobilize individuals with restricted movement abilities caused by trauma or other conditions. It is suitable for both passive and active motion training. Therapy with active-passive exercise devices promotes rehabilitation through natural and rhythmic movements. It accommodates a wide range of patients-from wheelchair users to those capable of walking-by enabling nearly all individuals in the rehabilitation process to actively participate in cycling exercises .

However, there is a limited body of research exploring the relationship between cognitive and motor performance functions during THERA-Trainer-based exercises. This study aims to address this gap by providing clinicians with insights into progression during evaluation and treatment phases, enhancing therapeutic strategies, and contributing to the academic knowledge base for researchers.
