Effects Of Underwater Treadmill Exercise On Percutaneous Oxygen Tension And Exercise Capacity In Low Limbs Of Peripheral Arterial Disease

Objective:The purpose of this study was to observe the effects of conventional treatment,land treadmill training(LTT)and underwater treadmill training(UWTT)on the percutaneous oxygen tension and exercise capacity in low limbs of peripheral arterial disease(PAD),we found an optimal treatment for patients with peripheral arterial disease and explore its therapeutic mechanism.Method:A total of 58 patients with mild to moderate peripheral arterial disease were enrolled.According to the random number table method,18 patients in the control group(group A),20 patients in the land treadmill training group(group B),and 20 patients in the underwater treadmill training group(group C).All three groups received regular statin therapy and received health education.In addition,group B and group C were given land treadmill training and underwater treadmill training on the basis of conventional drug treatment.The training frequency is 1 time per day,5 days a week for 12 weeks.After 12 weeks,the following indexes were observed before and after treatment:Ankle-Brachial Index(ABI);PAD exercise-related indicators:exercise treadmill test,transcutaneous oxygen tension(TcP02),6-minute walking distance test(6MWDT)and walking impairment questionnaire(WIQ);skeletal muscle strength and balance ability related indicators:muscle strength test,Fullerton advanced balance Scale(FAB-scale).Result:1.There was no significant difference in the general data of age,sex and duration of disease between the three groups before treatment(P>0.05).2.After 12 weeks in group A,there was no significant improvement in Ankle-Brachial Index,exercise capacity,skeletal muscle strength and balance ability.3.Group B patients had significant improvement in ABI,exercise treadmill test,TcP02,6MWDT,WIQ,muscle strength test,FAB scale and other indicators(P<0.05 or P<0.01).4.Group C patients had significant improvement in ABI,exercise treadmill test,TcP02,6MWDT,WIQ,muscle strength test,FAB scale and other indicators(P<0.05 or P<0.01),and exercise treadmill test,6MWDT,muscle strength test and FAB scale were superior to group B(P<0.05 or P<0.01).Conclusion:1.Patients with peripheral arterial disease are treated with conventional medication only,and their Ankle-Brachial Index,exercise capacity,and skeletal muscle strength and balance are not improved.2.Rehabilitation training with land treadmill training as the core can effectively improve the Ankle-Brachial Index,exercise capacity,skeletal muscle strength and balance ability of patients with peripheral arterial disease,and improve the quality of life of patients.3.Rehabilitation training with underwater treadmill training as the core can better improve the Ankle-Brachial Index,exercise capacity,skeletal muscle strength and balance ability of patients with peripheral arterial disease,and the physical function,quality of life,pain and spirit of the patient.Improvements in health and other aspects are also superior to land treadmill training.
