Vascular issues like PAOD and DVT are common in patients with diabetes, obesity, or immobility due to increased resistance and reduced blood flow. Traditional treatments (medication or surgery) are not always feasible, prompting interest in TENS as an alternative. Although primarily used for pain relief, TENS may enhance blood flow. This research compares different stimulation frequencies (80 Hz vs. 4 Hz) and sites (gastrocnemius muscle vs. thoracolumbar sympathetic ganglia) to identify the most effective configuration.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
