Diaphragmatic Breathing Exercises With KOTS Currents in Patients With Long COVID (KOTS-LC)
Effects of Diaphragmatic Breathing Exercises Combined With Diaphragmatic Electrostimulation Using KOTS Currents in Patients With Long COVID: A Pilot Randomized Controlled Trial
Přehled studie
Postavení
Detailní popis
Long COVID is a multifactorial condition that may be associated with persistent respiratory symptoms, reduced physical capacity, fatigue, dyspnea, and impaired quality of life. Respiratory rehabilitation strategies may contribute to improving breathing patterns and functional recovery in this population. Diaphragmatic breathing exercises are commonly used to promote respiratory control and diaphragmatic activation. In addition, KOTS currents, also known as Russian currents, are medium-frequency alternating currents used in physiotherapy to elicit muscle contraction and may be applied as a complementary strategy to stimulate the diaphragm.
This pilot randomized controlled trial will compare diaphragmatic breathing exercises alone with diaphragmatic breathing exercises combined with diaphragmatic electrostimulation using KOTS currents in patients diagnosed with Long COVID. Participants will be randomly allocated to either the control group or the intervention group. Both groups will receive a three-week intervention consisting of two sessions per week. The control group will perform diaphragmatic breathing exercises, whereas the intervention group will perform the same breathing exercises combined with diaphragmatic electrostimulation.
Assessments will be conducted before and after the intervention period. The study is intended to explore whether adding diaphragmatic electrostimulation to a respiratory exercise program may provide additional benefits compared with diaphragmatic breathing exercises alone in this population.

Experimentální: Diaphragmatic Breathing Exercises Plus KOTS Currents
Participants assigned to this arm will perform diaphragmatic breathing exercises combined with diaphragmatic electrostimulation using KOTS currents.
The intervention will be delivered twice per week for three weeks.
KOTS currents will be applied as medium-frequency alternating current stimulation, with stimulation intensity adjusted according to participant tolerance.
|
Diaphragmatic electrostimulation will be applied using KOTS currents, a medium-frequency alternating current stimulation.
Electrodes will be placed over the seventh and eighth rib region along the mammillary line.
Stimulation will be delivered in trains of 4 seconds of stimulation followed by 8 seconds of rest, with a carrier frequency of 2,500 Hz.
The standard treatment duration will be 15 minutes: 10 minutes at 30 Hz followed by 5 minutes at 70 Hz.
Stimulation intensity will be adjusted according to participant tolerance.
The intervention will be delivered twice per week for three weeks, together with diaphragmatic breathing exercises.
Ostatní jména:
Participants will perform diaphragmatic breathing exercises in a supine position with the knees flexed.
One hand will be placed on the chest and the other hand below the sternum.
Participants will be instructed to inhale through the nose while expanding the abdomen with minimal thoracic movement, and to exhale slowly through pursed lips.
The breathing pattern will include a 4-second inspiration and a 6-second expiration.
Exercises will be performed twice per week for three weeks.
