Efeito da massagem e pseudomassagem no desempenho agudo e recuperação autopercebida: um estudo controlado por placebo / Effect of massage and pseudo massage on acute performance and self-perceived recovery: a study placebo-controlled

RESUMO O objetivo deste estudo foi verificar o efeito da massagem ou pseudomassagem no desempenho do salto vertical. Quinze participantes foram submetidos aleatoriamente a três condições experimentais: massagem, pseudomassagem e repouso. A condição de massagem exigiu três saltos verticais unipodais seguidos de dois minutos de massagem manual nos músculos flexores plantares e, antes de executar outros três saltos, foi aplicada a Escala de Recuperação de Qualidade Total (TQR). As duas condições a seguir foram estruturadas com os mesmos procedimentos, no entanto, os participantes foram submetidos à pseudomassagem (simples-cego) ou a dois minutos de descanso. Os resultados não mostraram diferenças estatísticas na altura do salto entre as análises pré e pós, nem entre as condições experimentais (massagem 18,7 ± 4,1 vs. 18,2 ± 4,1; pseudomassagem 19,1 ± 4,0 vs. 18,3 ± 3,8; descanso 19,0 ± 4,0 vs. 18,7 ± 3,9 cm). Também não houve diferenças estatísticas no TQR entre as condições experimentais (massagem 16,2 ± 4,3; pseudomassagem 16,4 ± 3,9; descanso 15,9 ± 2,6 ua). Tanto a massagem quanto a pseudomassagem não afetaram o desempenho no salto vertical e na TQR.

ABSTRACT The aim of this study was to verify the effect of massage or pseudo massage on vertical jump performance. Fifteen participants were randomly subjected to three experimental conditions: massage, pseudo massage and rest. The massage condition required three unipodal vertical jumps followed by two minutes of manual massage on plantar flexor muscles and, before performing another three jumps, the Total Quality Recover Scale (TQR) was applied. The two following conditions were structured with the same procedures, although participants were submitted either at pseudo massage (single-blinded) or two minutes of rest. Results showed no statistical differences on jump height between pre and post analysis nor between experimental conditions (massage 18.7 ± 4.1 vs 18.2 ± 4.1; pseudo massage 19.1 ± 4.0 vs 8.3 ± 3.8; rest 19.0 ± 4.0 vs 18.7 ± 3.9 cm). There were also no statistical differences in the TQR results between experimental conditions (massage 16.2 ± 4.3; pseudo massage 16.4 ± 3.9; rest 15.9 ± 2.6 ua). Both massage and pseudo massage did not affect performance on vertical jump and TQR.

Oil massage in neonates: an open randomized controlled study of coconut versus mineral oil.

INTRODUCTION: Oil massage for newborns is reported to improve weight gain by better thermoregulation. A role for transcutaneous absorption has also been suggested. AIMS AND OBJECTIVES: This study was undertaken to compare the effect of massage with coconut oil versus mineral oil and placebo (powder) on growth velocity and neuro-behavior in well term and preterm babies. STUDY DESIGN: Open Randomized Controlled trial. SETTING: The Premature unit and the postnatal wards of a major teaching hospital in a metropolitan city. MATERIAL AND METHODS: Intramural preterm appropriate for gestational age babies weighing between 1500 to 2000 grams and term births weighing more than 2500 grams fulfilling the inclusion criteria constituted the two gestation age categories studied. Babies in each group were randomized to receive massage with either coconut oil, mineral oil or with placebo. Oil massage was given by a trained person from day 2 of life till discharge, and thereafter by the mother until 31 days of age, four times a day. Babies were followed up daily till discharge and every week after discharge for anthropometry. Neuro-behavioral outcome was assessed by the Brazelton Score at baseline, day 7 and on day 31. RESULTS: Coconut oil massage resulted in significantly greater weight gain velocity as compared to mineral oil and placebo in the preterm babies group; and in the term baby group, as compared to the placebo. Preterm infants receiving coconut oil massage also showed a greater length gain velocity compared to placebo group. No statistically significant difference was observed in the neurobehavioral assessment between all three subgroups in term babies as well as in preterm babies.

Estudo das variaçöes da pressäo intra-ocular / Intra-ocular pressure variations during accomodative convergence and convergence with prims

Foram estudados 90 pcientes normais, selecionados aps um exame oftalmológico geral, ols quais foram divididos em 3 grupos (I, II e III). Nos pacientes do grupo I, estudamos as variaçöes da pressäo intra-ocular durante a convergência acomodativa assimétrica. Nos pacientes do grupo II, as variaçöes da pressäo intra-ocular foram estudadas após um tempo de cincominutos de exercício convergencial para longe, com prismas. Os pacientes do grupo II representaram o grupo controle em que nenhum exame ou manobra foram realizados durante 5 minutos, tendo pressöes intra-oculares sido medidas antes e após esse tempo. Houve para o grupo I um aumento estatisticamente significativo das pressöes intra-oculares, em média 3,26 mmHg. Para o grupo II houve uma queda significativa das pressöes intra-oculares, em média -0,9 mmHg. No grupo III, controle, näo houve alteraçöes das pressöes intra-oculares. Säo discutidas as causas de variaçäo das press 8es intra-oculares em cada grupo atribuindo-se, no grupo I, à co-contrataçäo dos m3sculos reto medial e lateral. No grupo II devem-se, provavelmente, à contraçäo prolongada do músculo reto medial através de um fenômeno de massagem. Embora tenha havido alteraçöes estatisticamente significativas nas pressöes intra-oculares nos dois primeiros grupos, estas variaçöes s-o relativamente pequenas e, provavelmente, carecem de significado clínico no olho normal
