Respiratory Rehabilitation Based on Eccentric Exercice on Treadmill After Thoracic Surgery

Summary

Thoracic surgeries are frequent and pulmonary rehabilitation is essential, since one of the problems that these patients present is dyspnea when performing aerobic exercise, which limits improvement and in some cases causes them to abandon physical exercise. Thanks to carrying out a correct effort retraining program, combining respiratory physiotherapy with therapeutic exercise, patients with respiratory pathologies manage to improve lung capacity and ventilatory mechanics, increase muscle strength and aerobic resistance, prevent long- term complications, reduce fatigue and, ultimately, improve your quality of life.

Likewise, it is important to find the most appropriate type of muscular work that produces more benefits in the short and medium term to optimize our resources.The objective of the study is to demonstrate the effectiveness of eccentric training in patients who have undergone thoracic surgery, in terms of strength, lung capacity, functionality and quality of health in the short and medium term.

For this purpose, a randomized clinical trial has been designed, with a blinded examiner, following the CONSORT guideline for clinical trials and the ethical principles of the Declaration of Helsinki. A total sample of 57 subjects has been estimated. The study is aimed at patients after scheduled thoracic surgery. A program of 12 group sessions spread over 4 weeks will be carried out. Each of them will last 75 minutes and will include strength and respiratory physiotherapy exercises, common to all subjects.

Aerobic interval training will depend on the group assigned: treadmill with negative slope (experimental group), treadmill with positive slope (control group 1) or cycle ergometer (control group 2). On the first and last day of treatment, as well as one month after completing the intervention, the following variables will be measured: thickness, cross-sectional area and ultrasound intensity of the rectus femoris; diaphragmatic excursion and thickness; 6 minute walk test; Borg scale; maximum respiratory pressures; sit-to-stand test; grip strength in both hands; spirometric assessment of FEV1 and SF-12 health quality questionnaire. a

Retraining program after thoracic surgery

An effort retraining program will be carried out, with respiratory physiotherapy, muscle strengthening exercises and aerobic exercise, for four weeks, every other day, with a duration of 75 minutes each session. Both the control and experimental groups will receive a common treatment: Muscle strength and aerobic resistance exercises will be performed following the F.I.T.T principle, working the main muscle groups against resistance (between 40% and 60% RM) performing three sets of ten repetitions of each one. It will begin with a warm-up and then a cool down with stretching. We will apply respiratory physiotherapy techniques to promote ventilation and drainage of secretions. Next, the aerobic work is carried out according to the assigned group: treadmill with a positive slope (experimental group), treadmill with a negative slope (control 1) or cycle ergometer (group 2).
