Characterization of the Effects on Bioimpedance and the Sensorimotor System After the Application of Percutaneous Electrolysis Protocols on the Patellar Tendon.
In Brief
A clinical study evaluating High-intensity and short-duration, Low-intensity and long-duration, and 2 other interventions for Healthy. Completed, enrolled 50 participants across 1 site.
Detailed Summary
Percutaneous electrolysis is a physical therapy technique, whose main objective is the treatment of the signs and symptoms associated with tendinopathies by applying a galvanic current through a blunt dry needle. Despite its clinical use being already stablished, the physiological mechanisms underlying this therapy are still unknown and thus, the optimal parameterization. The present study proposes to perform different stimulation protocols of percutaneous electrolysis on healthy subjects patellar tendon to answer those questions.
Study Details
Timeline
Interventions
The ultrasound guided percutaneous electrolysis will be applied in the middle of the patellar tendon. The parameters will be 3 squared pulses of a high intensity current (3 mA), that will be applied for 3 seconds with 3 seconds rests between pulses and 1 second of pulses ramp. The current will be off on the first 348 seconds of the intervention approximately and the last 18 seconds it will be on. The total treatment time will be 366 seconds.
The ultrasound guided percutaneous electrolysis will be applied in the middle of the patellar tendon. The parameters will be 3 squared pulses of a low intensity direct current (0.1 mA) during 90 seconds, with 3 seconds rests between pulses and 1 second of pulses ramp. The total treatment time will be 366 seconds.
The ultrasound guided percutaneous electrolysis will be applied in the middle of the patellar tendon. The parameters will be 3 pulses of a high intensity compensated biphasic current (3 mA), during 3 seconds with 3 seconds rests between pulses and 1 second of pulses ramp. The alternating frequency will be of 20 Hz and the pulse width of 50 microseconds. The current will be off on the first 348 seconds of the intervention approximately and the last 18 seconds it will be on. The total treatment time will be 366 seconds.
The control ultrasound guided percutaneous electrolysis will be applied in the middle of the patellar tendon, without electrical stimulation during 366 seconds.
