Effects of TENS During the Performance of a Therapeutic Exercise Protocol in Individuals With Knee Osteoarthritis.
Trial Parameters
Brief Summary
Research participants diagnosed with knee Osteoarthritis will be randomized through a draw using sealed opaque envelopes indicating two groups: 1. Therapeutic Exercises + Transcutaneous electrical nerve stimulation and 2. Therapeutic Exercises + placebo Transcutaneous electrical nerve stimulation. Therefore, individuals of both sexes, aged 40 years or over, with a clinical diagnosis of unilateral osteoarthritis of the knee, who present with knee pain for more than three months, morning stiffness for less than 30 minutes, crepitus, bone sensitivity and absence of palpable heat, and diagnosis established radiographically (determined by Kellgren and Lawrence grade 1 to 3 on scale 1 to 4). Exclusion criteria are bilateral knee Osteoarthritis, hip Osteoarthritis, severe osteoporosis, fibromyalgia, clinical history of tumors or cancer, active inflammatory joint diseases (rheumatoid arthritis, gout), undergoing any lower extremity joint replacement, neurological disorders (Parkinson's disease, stroke, multiple sclerosis, muscular dystrophies, motor neuron disease, Alzheimer's disease), infected wounds or osteomyelitis in the knee region, deep vein thrombosis or thrombophlebitis, sensory changes in the lower limbs, cognitive impairment, and cardiopulmonary disorders that may prevent or limit the execution of exercises, use of a walking assistance device, history of recent trauma to the knee, having undergone any form of treatment involving physiotherapy, intra-articular corticosteroids, anti-inflammatories or chondroprotective within the six months before the start of interventions.
