The study aims to test this orthosis in a real- world setting to see if it can enhance mobility and stability for elderly individuals, potentially reducing falls and improving quality of life.

Training and Adaptation: Participants will undergo an initial training session to get accustomed to the orthosis, including donning and doffing, adjustment, and use in various environments (flat surfaces, inclines).\n 2. Assessment Protocol:\n* Before wearing the orthosis-after wearing the orthosis (power off)-after wearing the orthosis (power on)\n* Walking environment will include EMG (Electromyography) measurements, 6-minute walk test, 10-meter walk test, and comprehensive gait analysis using platforms like the GAITRite system.\n* Seating environment will include EMG (Electromyography) measurements and TUG test. 3. Safety Monitoring: Continuous monitoring of physiological responses (blood pressure, heart rate), musculoskeletal assessments, and skin integrity checks to monitor for adverse reactions or discomfort'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['OLDER_ADULT'], 'minimumAge': '65 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\nEligibility for participation in the study requires that all the following criteria are met:\n\n1.
