Περίληψη
Τα ποσοστά συμμετοχής των ασθενών με καρδιακή ανεπάρκεια σε προγράμματα επαναδραστηριοποίησης δεν είναι υψηλά και η εύρεση εναλλακτικών μορφών γύμνασης που θα είναι αποδεκτές και προσιτές από τους ασθενείς κρίνεται αναγκαία. Οι ελληνικοί παραδοσιακοί χοροί αποτελούν φυσική δραστηριότητα που έχει βρεθεί ότι μπορεί να επιφέρει ευνοϊκές προσαρμογές στα διάφορα συστήματα, κυρίως υγιών ατόμων. Σκοπός της μελέτης αυτής ήταν να διαπιστωθεί εάν ένα πρόγραμμα φυσικής αποκατάστασης με ελληνικούς παραδοσιακούς χορούς είναι ικανό να επηρεάσει τη λειτουργική ικανότητα και την ποιότητα ζωής ασθενών με καρδιακή ανεπάρκεια. Στη μελέτη συμμετείχαν συνολικά 51 ασθενείς με καρδιακή ανεπάρκεια Ι και ΙΙ βαθμού κατά NYHA, ηλικίας 67.2± 5.5 έτη, που διαιρέθηκαν τυχαία σε τρεις ομάδες: στην ομάδα Α (18 ασθενείς), η οποία συμμετείχε σε πρόγραμμα 8μηνης γύμνασης με ελληνικούς παραδοσιακούς χορούς, στηνtraining programs in CHF remains high mainly due to the lack of enthusiasm among participants. To stimulate patients to rehabilitation programs, alternative forms of exercise are requested. Traditional dancing is a form of exercise that combines movement, social interaction and fun. The aim of the present study was to examine whether an exercise training program with Greek traditional dances improves functional capacity and quality of life in patients with CHF, and is capable to increase the compliance of the participants. Fifty-one male patients with heart failure of NYHA class I and II and mean age 67.1±5.5 years, volunteered to participate in the 8-month study and were randomly assigned to an exercise training with Greek traditional dances group (group A, n=18), a mixed-type exercise training group (group B, n=16) or sedentary group that served as control (group C, n=17). At entry and at the end of the study all patients underwent a cardiopulmonary exercise and isokinetic strength testing and were also tested on 6-min walk test, sit to stand test and Berg Balance Scale (BBS). Moreover, health-related quality of life was assessed using two questionnaires; the 36-item short form health survey (SF-36) and Life Satisfaction Inventory (LSI). The Intrinsic Motivation Inventory (IMI) was also used to assess participants' subjective experience. At the beginning of the study all patients had similar means at all measurements without statistical significant differences. At the end of the 8-month study VO2peak increased by 34% (p<0.05) in group A and by 32.5% (p<0.05) in group B, VO2AT by 11% (p<0.05) in A and by 10.5% (p<0.05) in B, exercise time by 48.5% (p<0.05) and 46.5% (p<0.05), VE by 15% (p<0.05) and 14% (p<0.05) and O2 pulse by 30% (p<0.05) in group A and by 36.5% (p<0.05) in B, respectively. Moreover, after training VE/VCO2 slope was decreased by 18% (p<0.05) in group A and by 19.5% (p<0.05) in group B. Regarding the functional ability measurements at the end of the study, the maximum distance walk in the six-minute test significantly increased by 20.5% (p<0.05) in group A and by 18.5% (p<0.05) in B, while the time in the sit to stand test decreased by 20.5% (p<0.05) in A and by 22% (p<0.05) in B. Moreover, the BBS increased by 6% (p<0.05) in both groups and the maximal isometric force of lower limbs by 39% (p<0.05) in group A and by 43.5% (p<0.05) in B. A significant improvement was revealed in the total score of SF-36 by 8% (p<0.05) in group A and by 7% (p<0.05) in group B, as a result of the improvements observed in physical health subscale by 8% (p<0.05) in A and 6.5% (p<0.05) in B and in mental health subscale by 7.5% (p<0.05) in A and by 6.5% (p<0.05) in B. Moreover, the LSI score was found to be significant increased in group A by 18% (p<0.05) and in B by 20.5% (p<0.05). The IMI score was increased only in group A by 26.2% (p<0.05). The change in L.S.I. score in group A was correlated with changes in distance walk in the six-minute test (r=0.584, p<0.05), in exercise time (r=0.551, p<0.05) and in mental health subscale of SF-36 questionnaire (r=0.596, p<0.05). Furthermore, the improvement in VO2peak was correlated with the improvement in physical health subscale of SF-36 (r=0.602, p<0.05) and total score of I.M.I. (r=0.607, p<0.05). In conclusion, the results indicate that exercise training with Greek traditional dances is feasible and able to improve functional capacity and quality of life, similar to traditional mixed exercise training in CHF patients, and well motivate patients to complete the program. Exercise with Greek traditional dances may be considered as an alternative way to exercise CHF patients.
