Effects of physiotherapeutic instructions on anxiety of CABG patients

INTRODUCTION The coronary artery bypass graft surgery is an option of treatment for cardiovascular diseases, and the patients who underwent such procedure can suffer from preoperative anxiety. OBJECTIVE The aim of this study is to verify the effects of physiotherapeutic instructions at the anxiety level on patients undergone coronary artery bypass graft surgery. METHODS Randomized clinical trial, with the sample composed by 51 individuals, 27 on the control group and 24 on the intervention; on which it was assessed the anxiety (Beck Scale for Anxiety) and pain (Visual Analog Scale) levels on the pre- and postoperative period and only the second group received instructions about the surgery procedures and ventilatory exercises. For statistical analysis the Wilcoxon, Mann-Whitney and Spearman tests were used. RESULTS The lower anxiety levels were observed in patients that received the intervention on the period before surgery (9.6 +/- 7.2 versus 13.4 +/- 5.9, P=0.02). On the control group, the difference among the anxiety levels before and after the surgery was statistically significant (P= 0.003). The female individuals presented more anxious before the surgery compared to the male ones (P=0.058). It was also verified a relationship between length of stay at hospital and postoperative anxiety (P=0.05), where the more anxious individuals remained more time at the hospital. CONCLUSION Patients oriented and instructed about physiotherapeutic ventilatory exercises and hospital routine, presented their levels of anxiety reduced on the preoperative compared to the control group. However, at the postoperative, both groups presented their anxiety levels reduced without significant difference between them.

Efeitos da crioterapia e facilitação neuromuscular proprioceptiva sobre a força muscular nas musculaturas flexora e extensora de joelho

As musculaturas flexora e extensora do joelho sao frequentemente lesionadas devido a um desequilibrio entre esses grupos. Recursos termicos, como a crioterapia, e tecnicas de alongamento, como a tecnica mantem-relaxa da facilitacao neuromuscular proprioceptiva (FNP), influenciam a flexibilidade e forca muscular, proporcionando maior homogeneidade entre essas musculaturas e diminuindo a incidencia de lesoes. Este estudo objetivou verificar os efeitos da crioterapia e da FNP sobre a forca das musculaturas flexora e extensora de joelho. A amostra foi composta por 18 mulheres com idade entre 18 e 24 anos, nao-praticantes de atividade fisica regular, divididas em dois grupos: um submetido a crioterapia e o outro a tecnica mantem-relaxa da FNP. Antes e apos uma sessao de aplicacao das tecnicas foi feita avaliacao isocinetica. A aplicacao da tecnica mantem-relaxa provocou aumento da forca em ambas as musculaturas em ambos os membros, atingindo nivel de significância nos flexores do membro inferior direito (p=0,04). A crioterapia diminuiu a forca dos extensores e exerceu efeito contrario sobre os flexores, tendo gerado aumento significativo nos flexores do membro inferior direito (p=0,035). Quando comparadas as tecnicas, a tecnica mantem-relaxa gerou maiores valores de pico de torque, principalmente nos extensores do membro inferior esquerdo (p=0,042). Conclui-se que a tecnica mantem-relaxa da FNP gerou maiores valores no pico de torque em relacao a crioterapia.
