Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Controlled clinical trial, two arms randomized and blind.
Primary Study Purpose

TREATMENT

Blinding Strategy

SINGLE

Outcome Assessors
Two physiotherapists will be responsible for recruiting and assessing inclusion and exclusion criteria. Therefore, a rheumatologist will be responsible for confirming the OA diagnosis of research participants. A researcher will be responsible for the randomization process. Two physiotherapists, blinded to randomization, will be responsible for the assessment procedures. Two other physiotherapists, one for each group, will apply the interventions.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Therapeutic exercise and Transcutaneous electrical nerve stimulation

The therapeutic exercise program includes a warm-up, resistance, neuromuscular, mobility, and balance exercises. Therapeutic exercises will be performed in up to three sets of 8-12 repetitions or 30-60 seconds each, with rest intervals of 90 seconds between sets. Therapeutic exercises will be performed in up to three sets of 8-12 repetitions or 30-60 seconds each, with rest intervals of 90 seconds between sets. TENS will be applied with a portable device during the therapeutic exercise program. The equipment has a two-phase and pulsed symmetric quadratic waveform. 5x5cm adhesive electrodes will be applied to the lateral and medial edges and superior and inferior to the patella, in a crossed manner, surrounding the region.

Group Type EXPERIMENTAL

Therapeutic exercise

Intervention Type OTHER

The therapeutic exercise program includes a warm-up, resistance, neuromuscular, mobility, and balance exercises. Therapeutic exercises will be performed in up to three sets of 8-12 repetitions or 30-60 seconds each, with rest intervals of 90 seconds between sets.

Transcutaneous electrical nerve stimulation

Intervention Type DEVICE

TENS will be applied with a portable device, Neurodyn Portable System from Ibramed, while carrying out the entire therapeutic exercise program. The equipment has a two-phase and pulsed symmetric quadratic waveform. 5x5cm adhesive electrodes will be applied to the lateral and medial edges and superior and inferior to the patella, in a crossed manner, surrounding the region.

The parameters established for the protocol of this study are based on a survey already carried out, with continuous pulse mode, frequency of 150Hz, duration of 150us, and amplitude varying from 1-60mA or more as long as tolerated by the study participant, without causing pain. The application time will be proportional to the time of the exercise session, approximately 60 minutes. The researcher will evaluate the need to adjust the current intensity through the pulse amplitude regularly so that the stimulus does not accommodate.

Therapeutic exercise and Placebo Transcutaneous electrical nerve stimulation

Participants in the control group will perform the same therapeutic exercise protocol previously reported in the experimental group, associated with placebo TENS. To do this, the device will only be turned on during the first minute of therapeutic exercises. The same TENS parameters as the experimental group will be applied for this.
