Exploring the Effect of the Hypershell Hip Exoskeleton on Fatiguing, Everyday Activities in Older Adults

The goal of this clinical trial is to learn how wearing the Hypershell lower-limb exoskeleton affects perceived fatigue during everyday mobility activities in adults aged 65 years and older. The main questions it aims to answer are: * Does active assistance from the Hypershell reduce the development of perceived fatigue during repeated everyday mobility tasks? * Does wearing the Hypershell affect how long participants can perform the protocol and how many tasks they can complete before reaching a high level of fatigue? * How do participants perceive the usability, comfort, and overall experience of using the Hypershell? * What are the biomechanical and physiological responses from wearing the Hypershell? Researchers will compare two conditions: performing the mobility protocol without the Hypershell and wearing the Hypershell with active assistance. Participants will: * Attend one baseline session including questionnaires, physical tests, and familiarization with the Hypershell and study procedures. * Attend two experimental sessions in a randomized order, with at least one week between sessions. * Complete a laboratory-based mobility protocol including daily activities such as standing up from a chair, walking, stair climbing, slope walking, walking on uneven surfaces, carrying an object, and performing a cognitive task while walking. * Report their perceived fatigue throughout the protocol using the Borg CR10 scale. * Wear non-invasive sensors that measure physiological responses and movement during the experimental sessions. * Provide feedback about their experience using the HyperShell.
