Massage for promoting growth and development of preterm and/or low birth-weight infants

Maternally administered interventions for preterm infants in the NICU: effects on maternal psychological distress and mother-infant relationship

Although studies have examined the effects of interventions focused on preterm infants, few studies have examined the effects on maternal distress (anxiety, depressive symptoms, post-traumatic stress symptoms, parenting stress) or parenting. This study examined the effects of the auditory-tactile-visual-vestibular (ATVV) intervention and kangaroo care (KC) on maternal distress and the mother-infant relationship compared to an attention control group. 240 mothers from four hospitals were randomly assigned to the three groups. Maternal characteristics in the three groups were similar: 64.1% of ATVV mothers, 64.2% of KC mothers, and 76.5% of control mothers were African American; maternal age averaged 26.3 years for ATVV mothers, 28.1 for KC mothers, and 26.6 for control mothers; and years of education averaged 13.6 for ATVV and KC mothers, and 13.1 for control mothers. Mothers only differed on parity: 68.4% of ATVV and 54.7% of KC mothers were first-time mothers as compared to 43.6% of control mothers. Their infants had a similar mean gestational ages (27.0 weeks for ATVV, 27.2 for KC, and 27.4 for control) and mean birthweights (993 g for ATVV, 1022 for KC, and 1023 for control). Mothers completed questionnaires during hospitalization, and at 2, 6 and 12 months corrected age on demographic characteristics, depressive symptoms, state anxiety, post-traumatic stress symptoms, parenting stress, worry about child health, and child vulnerability (only at 12 months). At 2 and 6 months, 45-min videotapes of mother-infant interactions were made, and the HOME Inventory was scored. Behaviors coded from the videotapes and a HOME subscale were combined into five interactive dimensions: maternal positive involvement and developmental stimulation and child social behaviors, developmental maturity, and irritability. Intervention effects were examined using general linear mixed models controlling for parity and recruitment site. The groups did not differ on any maternal distress variable. Kangaroo care mothers showed a more rapid decline in worry than the other mothers. The only interactive dimensions that differed between the groups were child social behaviors and developmental maturity, which were both higher for kangaroo care infants. Change over time in several individual infant behaviors was affected by the interventions. When mothers reported on the interventions they performed, regardless of group assignment, massage (any form including ATVV) was associated with a more rapid decline in depressive symptoms and higher HOME scores. Performing either intervention was associated with lower parenting stress. These findings suggest that as short-term interventions, KC and ATVV have important effects on mothers and their preterm infants, especially in the first half of the first year.

Massage therapy for essential hypertension: a systematic review

Massage, an ancient Chinese healing art, is widely practiced for symptom relief in hypertensive patients with anxiety, depression, headache, vertigo, chronic pain in neck, shoulder and back. A large number of case series and clinical trials have been published. However, it is still unclear whether massage can be recommended as an effective therapy for essential hypertension (EH). We estimated the current clinical evidence of massage for EH. Articles published before 10 December 2013 were searched using Cochrane Library, PubMed, EMBASE, Chinese Scientific Journal Database (VIP), Chinese Biomedical Literature Database, Wanfang data and Chinese National Knowledge Infrastructure. Randomized controlled trials comparing massage with any type of control intervention were included. Trials testing massage combined with antihypertensive drugs versus antihypertensive drugs were included as well. Meta-analysis was performed on the effects on blood pressure (BP). Twenty-four articles involving 1962 patients with EH were selected. Methodological quality of most trials was evaluated as generally low. Meta-analyses demonstrated that massage combined with antihypertensive drugs may be more effective than antihypertensive drugs alone in lowering both systolic BP (SBP; mean difference (MD): -6.92 (-10.05, -3.80); P<0.0001) and diastolic BP (MD: -3.63 (-6.18, -1.09); P=0.005); massage appears beneficial for reducing SBP (MD: -3.47 (-5.39, -1.56); P=0.0004) for hypertensive patients as compared with antihypertensive drugs. Safety of massage is still unclear. There is some encouraging evidence of massage for EH. However, because of poor methodological quality, the evidence remains weak. Rigorously designed trials are needed to validate the use of massage in future.

Efficacy of baby-CIMT: study protocol for a randomised controlled trial on infants below age 12 months, with clinical signs of unilateral CP

Background

Infants with unilateral brain lesions are at high risk of developing unilateral cerebral palsy (CP). Given the great plasticity of the young brain, possible interventions for infants at risk of unilateral CP deserve exploration. Constraint-induced movement therapy (CIMT) is known to be effective for older children with unilateral CP but is not systematically used for infants. The development of CIMT for infants (baby-CIMT) is described here, as is the methodology of an RCT comparing the effects on manual ability development of baby-CIMT versus baby-massage. The main hypothesis is that infants receiving baby-CIMT will develop manual ability in the involved hand faster than will infants receiving baby-massage in the first year of life.

Method and design

The study will be a randomised, controlled, prospective parallel-group trial. Invited infants will be to be randomised to either the baby-CIMT or the baby-massage group if they: 1) are at risk of developing unilateral CP due to a known neonatal event affecting the brain or 2) have been referred to Astrid Lindgren Children’s Hospital due to asymmetric hand function. The inclusion criteria are age 3–8 months and established asymmetric hand use. Infants in both groups will receive two 6-weeks training periods separated by a 6-week pause, for 12 weeks in total of treatment. The primary outcome measure will be the new Hand Assessment for Infants (HAI) for evaluating manual ability. In addition, the Parenting Sense of Competence scale and Alberta Infant Motor Scale will be used. Clinical neuroimaging will be utilized to characterise the brain lesion type. To compare outcomes between treatment groups generalised linear models will be used.

Discussion

The model of early intensive intervention for hand function, baby-CIMT evaluated by the Hand Assessment for Infants (HAI) will have the potential to significantly increase our understanding of how early intervention of upper limb function in infants at risk of developing unilateral CP can be performed and measured.

Physical activity programs for promoting bone mineralization and growth in preterm infants

BACKGROUND

Lack of physical stimulation may contribute to metabolic bone disease of preterm infants, resulting in poor bone mineralization and growth. Physical activity programs combined with adequate nutrition might help to promote bone mineralization and growth.

OBJECTIVES

The primary objective was to assess whether physical activity programs in preterm infants improve bone mineralization and growth and reduce the risk of fracture.The secondary objectives included other potential benefits in terms of length of hospital stay, skeletal deformities and neurodevelopmental outcomes, and adverse events.Subgroup analysis:• Given that the smallest infants are most vulnerable for developing osteopenia (Bishop 1999), a subgroup analysis was planned for infants with birth weight < 1000 g.• Calcium and phosphorus intake may affect an infant's ability to increase bone mineral content (Kuschel 2004). Therefore, an additional subgroup analysis was planned for infants receiving different amounts of calcium and phosphorus, along with full enteral feeds as follows. ∘ Below 100 mg/60 mg calcium/phosphorus or equal to/above 100 mg/60 mg calcium/phosphorus per 100 mL milk. ∘ Supplementation of calcium without phosphorus. ∘ Supplementation of phosphorus without calcium.

SEARCH METHODS

The standard search strategy of the Cochrane Neonatal Review Group (CNRG) was used. The search included the Cochrane Central Register of Controlled Trials (CENTRAL) (2012, Issue 9), MEDLINE, EMBASE, CINAHL (1966 to March 2013), and cross-references, as well as handsearching of abstracts of the Society for Pediatric Research and the International Journal of Sports Medicine.

SELECTION CRITERIA

Randomized and quasi-randomized controlled trials comparing physical activity programs (extension and flexion, range-of-motion exercises) versus no organized physical activity programs in preterm infants.

DATA COLLECTION AND ANALYSIS

Data collection, study selection, and data analysis were performed according to the methods of the CNRG.

MAIN RESULTS

Eleven trials enrolling 324 preterm infants (gestational age 26 to 34 weeks) were included in this review. All were small (N = 16 to 50) single-center studies that evaluated daily physical activity for three and one-half to eight weeks during initial hospitalization. Methodological quality and reporting of included trials were variable.Four trials demonstrated moderate short-term benefits of physical activity for bone mineralization at completion of the physical activity program. The only trial assessing long-term effects on bone mineralization showed no effect of physical activity administered during initial hospitalization on bone mineralization at 12 months corrected age. Meta-analysis from four trials demonstrated a positive effect of physical activity on daily weight gain (weighted mean difference (WMD) 2.21 g/kg/d, 95% confidence interval (CI) 1.23 to 3.19). Data from four trials showed a positive effect on linear growth (WMD 0.12 cm/wk, 95% CI 0.01 to 0.24) but not on head growth (WMD -0.03 cm/wk, 95% CI -0.14 to 0.08) during the study period. Only one trial reported on fractures (this outcome did not occur in intervention and control groups) and complications of preterm birth (no significant differences between intervention and control groups). None of the trials assessed other outcomes relevant to this review.

AUTHORS' CONCLUSIONS

Some evidence suggests that physical activity programs might promote short-term weight gain and bone mineralization in preterm infants. Data are inadequate to allow assessment of harm or long-term effects. Current evidence does not support the routine use of physical activity programs in preterm infants. Further trials incorporating infants with a high baseline risk of osteopenia are required. These trials should address adverse events, long-term outcomes, and the effects of nutritional intake (calories, protein, calcium, phosphorus).

Electroencephalographic activity of preterm infants is increased by Family Nurture Intervention: a randomized controlled trial in the NICU

OBJECTIVE

To assess the impact of Family Nurture Intervention (FNI) on electroencephalogram (EEG) activity in preterm infants (26-34 weeks gestation).

METHODS

Two groups were tested in a single, level IV neonatal intensive care unit (NICU; standard care or standard care plus FNI) using a randomized controlled trial design. The intervention consists of sessions designed to achieve mutual calm and promote communication of affect between infants and their mothers throughout the NICU stay. EEG recordings were obtained from 134 infants during sleep at ∼35 and ∼40 weeks postmenstrual age (PMA). Regional brain activity (power) was computed for 10 frequency bands between 1 and 48 Hz in each of 125 electrodes.

RESULTS

Near to term age, compared to standard care infants, FNI infants showed robust increases in EEG power in the frontal polar region at frequencies 10 to 48 Hz (20% to 36% with p-values <0.0004). Effects were significant in both quiet and active sleep, regardless of gender, singleton-twin status, gestational age (26-30 or 30-35 weeks) or birth weight (<1500 or >1500 g).

CONCLUSION

FNI leads to increased frontal brain activity during sleep, which other investigators find predictive of better neurobehavioral outcomes.

SIGNIFICANCE

FNI may be a practicable means of improving outcomes in preterm infants.

Randomized controlled trial of Family Nurture Intervention in the NICU: assessments of length of stay, feasibility and safety

BACKGROUND

While survival rates for preterm infants have increased, the risk for adverse long-term neurodevelopmental and behavioral outcomes remains very high. In response to the need for novel, evidence-based interventions that prevent such outcomes, we have assessed Family Nurture Intervention (FNI), a novel dual mother-infant intervention implemented while the infant is in the Neonatal Intensive Care Unit (NICU). Here, we report the first trial results, including the primary outcome measure, length of stay in the NICU and, the feasibility and safety of its implementation in a high acuity level IV NICU.

METHODS

The FNI trial is a single center, parallel-group, randomized controlled trial at Morgan Stanley Children's Hospital for mothers and their singleton or twin infants of 26-34 weeks gestation. Families were randomized to standard care (SC) or (FNI). FNI was implemented by nurture specialists trained to facilitate affective communication between mother and infant during specified calming interactions. These interactions included scent cloth exchange, sustained touch, vocal soothing and eye contact, wrapped or skin-to-skin holding, plus family-based support interactions.

RESULTS

A total of 826 infants born between 26 and 34 weeks during the 3.5 year study period were admitted to the NICU. After infant and mother screening plus exclusion due to circumstances that prevented the family from participating, 373 infants were eligible for the study. Of these, we were unable to schedule a consent meeting with 56, and consent was withheld by 165. Consent was obtained for 150 infants from 115 families. The infants were block randomized to groups of N = 78, FNI and N = 72, SC. Sixteen (9.6%) of the randomized infants did not complete the study to home discharge, 7% of those randomized to SC and 12% of FNI infants. Mothers in the intervention group engaged in 3 to 4 facilitated one- to two-hour sessions/week. Intent to treat analyses revealed no significant difference between groups in medical complications. The mean length of stay was not significantly affected by the intervention.

CONCLUSION

There was no significant effect demonstrated with this intervention amount on the primary short-term outcome, length of stay. FNI can be safely and feasibly implemented within a level IV NICU.

Effect of body massage on increase of low birth weight neonates growth parameters: A randomized clinical trial

BACKGROUND

Admission of low birth-weight (LBW) neonates in neonatal intensive care unit (NICU) causes their deprivation of tactile and sensory stimulation.

OBJECTIVE

The purpose of this study was to evaluate efficacy of body massage on growth parameters (weight, height and head circumference) gain velocity of LBW in Yazd, Iran.

MATERIALS AND METHODS

A randomized clinical trial study was conducted on LBW neonates whom were admitted to NICU of Shahid Sadoughi Hospital, Yazd, Iran from March to December 2011. Neonates were randomly assigned to two groups. In group one, 20 neonates were received massage three times in a day for consecutive 14 days by their mothers. In group two, intervention consisted of standard and routine care as control group. The primary endpoints were efficacy in increase of mean of weight, height and head circumference that were evaluated 14 days after intervention, at ages one and two months. Secondary outcome was clinical side effects.

RESULTS

17 girls and 23 boys with mean gestational age of 34.4±1.22 weeks were evaluated. In the body massage group, only weight at the age of two months was significantly higher than the control group (mean±SD: 3250±305 vs. 2948±121 gr, p=0.005). No adverse events were seen in the two groups.

CONCLUSION

Body massage might be used as an effective and safe non-medical intervention for increasing of weight gain velocity in LBW preterm neonates.

Massage for promoting mental and physical health in typically developing infants under the age of six months

BACKGROUND

Infant massage is increasingly being used in the community with babies and their primary caregivers. Anecdotal reports suggest benefits for sleep, respiration and elimination, the reduction of colic and wind, and improved growth. Infant massage is also thought to reduce infant stress and promote positive parent-infant interaction.

OBJECTIVES

The aim of this review was to assess whether infant massage is effective in promoting infant physical and mental health in low-risk, population samples.

SEARCH METHODS

Relevant studies were identified by searching the following electronic databases up to June 2011: CENTRAL; MEDLINE; EMBASE; CINAHL; PsycINFO; Maternity and Infant Care; LILACS; WorldCat (dissertations); ClinicalTrials.gov; China Masters' Theses; China Academic Journals; China Doctoral Dissertations; China Proceedings of Conference. We also searched the reference lists of relevant studies and reviews.

SELECTION CRITERIA

We included studies that randomised healthy parent-infant dyads (where the infant was under the age of six months) to an infant massage group or a 'no-treatment' control group. Studies had to have used a standardised outcome measure of infant mental or physical development.

DATA COLLECTION AND ANALYSIS

Mean differences (MD) and standardised mean differences (SMD) and 95% confidence intervals (CIs) are presented. Where appropriate, the results have been combined in a meta-analysis using a random-effects model.

MAIN RESULTS

We included 34 studies, which includes one that was a follow-up study and 20 that were rated as being at high risk of bias.We conducted 14 meta-analyses assessing physical outcomes post-intervention. Nine meta-analyses showed significant findings favouring the intervention group for weight (MD -965.25 g; 95% CI -1360.52 to -569.98), length (MD -1.30 cm; 95% CI -1.60 to -1.00), head circumference (MD -0.81 cm; 95% CI -1.18 to -0.45), arm circumference (MD -0.47 cm; 95% CI -0.80 to -0.13), leg circumference (MD -0.31 cm; 95% CI -0.49 to -0.13), 24-hour sleep duration (MD -0.91 hr; 95% CI -1.51 to -0.30), time spent crying/fussing (MD -0.36; 95% CI -0.52 to -0.19), deceased levels of blood bilirubin (MD -38.11 mmol/L; 95% CI -50.61 to -25.61), and there were fewer cases of diarrhoea, RR 0.39; 95% CI 0.20 to 0.76). Non-significant results were obtained for cortisol levels, mean increase in duration of night sleep, mean increase in 24-hour sleep and for number of cases of upper respiratory tract disease and anaemia.Sensitivity analyses were conducted for weight, length and head circumference, and only the finding for length remained significant following removal of studies judged to be at high risk of bias. These three outcomes were the only ones that could also be meta-analysed at follow-up; although both weight and head circumference continued to be significant at 6-month follow-up, these findings were obtained from studies conducted in Eastern countries only. No sensitivity analyses were possible.We conducted 18 meta-analyses measuring aspects of mental health and development. A significant effect favouring the intervention group was found for gross motor skills (SMD -0.44; 95% CI -0.70 to -0.18), fine motor skills (SMD -0.61; 95% CI -0.87 to -0.35), personal and social behaviour (SMD -0.90; 95% CI -1.61 to -0.18) and psychomotor development (SMD -0.35; 95% CI -0.54 to -0.15); although the first three findings were obtained from only two studies, one of which was rated as being at high risk of bias, and the finding for psychomotor development was not maintained following following removal of studies judged to be at high risk of bias in a sensitivity analysis. No significant differences were found for a range of aspects of infant temperament, parent-infant interaction and mental development. Only parent-infant interaction could be meta-analysed at follow-up, and the result was again not significant.

AUTHORS' CONCLUSIONS

These findings do not currently support the use of infant massage with low-risk groups of parents and infants. Available evidence is of poor quality, and many studies do not address the biological plausibility of the outcomes being measured, or the mechanisms by which change might be achieved. Future research should focus on the impact of infant massage in higher-risk groups (for example, demographically and socially deprived parent-infant dyads), where there may be more potential for change.

Effect of osteopathic manipulative treatment on length of stay in a population of preterm infants: a randomized controlled trial

Background

The use of osteopathic manipulative treatment (OMT) in preterm infants has been documented and results from previous studies suggest the association between OMT and length of stay (LOS) reduction, as well as significant improvements in several clinical outcomes. The aim of the present study is to investigate the effect of OMT on LOS in premature infants.

Methods

A randomized controlled trial was conducted on preterm newborns admitted to a single NICU between 2008-2009. N=110 subjects free of medical complications and with gestational age >28 and < 38 weeks were enrolled and randomized in two groups: study group (N=55) and control group (N=55). All subjects received routine pediatric care and OMT was performed to the study group for the entire period of hospitalization. Endpoints of the study included differences in LOS and daily weight gain.

Results

Results showed a significant association between OMT and LOS reduction (mean difference between treated and control group: -5.906; 95% C.I. -7.944, -3.869; p<0.001). OMT was not associated to any change in daily weight gain.

Conclusions

The present study suggests that OMT may have an important role in the management of preterm infants hospitalization.

Massage improves growth quality by decreasing body fat deposition in male preterm infants

OBJECTIVES

To assess the effect of massage on weight gain and body fat deposition in preterm infants.

STUDY DESIGN

Preterm infants (29-32 weeks) were randomized to the massage group (n = 22, 12 girls, 10 boys) or the control group (n = 22, 12 girls, 10 boys). Treatment was masked with massage or control care administered twice-daily by licensed massage therapists (6 d/wk for 4 weeks). Body weight, length, Ponderal Index (PI), body circumferences, and skinfold thickness (triceps, mid-thigh, and subscapular [SSF]) were measured. Circulating insulin-like growth factor I, leptin, and adiponectin levels were determined by enzyme-linked immunosorbent assay. Daily dietary intake was collected.

RESULTS

Energy and protein intake as well as increase in weight, length, and body circumferences were similar. Male infants in the massage group had smaller PI, triceps skinfold thickness, mid-thigh skinfold thickness, and SSF and increases over time compared with control male infants (P < .05). Female infants in the massage group had larger SSF increases than control female infants (P < .05). Circulating adiponectin increased over time in control group male infants (group × time × sex interaction, P < .01) and was correlated to PI (r = 0.39, P < .01).

CONCLUSIONS

Twice-daily massage did not promote greater weight gain in preterm infants. Massage did, however, limit body fat deposition in male preterm infants. Massage decreased circulating adiponectin over time in male infants with higher adiponectin concentrations associated with increased body fat. These findings suggest that massage may improve body fat deposition and, in turn, growth quality of preterm infants in a sex-specific manner.

A randomized placebo-controlled trial of massage therapy on the immune system of preterm infants

OBJECTIVES

The aim of this study was to investigate the effects of massage therapy (MT) on the immune system of preterm infants. The primary hypothesis was that MT compared with sham therapy (control) will enhance the immune system of stable premature infants by increasing the proportion of their natural killer (NK) cell numbers.

METHODS

A randomized placebo-controlled trial of MT versus sham therapy (control) was conducted among stable premature infants in the NICU. Study intervention was provided 5 days per week until hospital discharge for a maximum of 4 weeks. Immunologic evaluations (absolute NK cells, T and B cells, T cell subsets, and NK cytotoxicity), weight, number of infections, and length of hospital stay were also evaluated.

RESULTS

The study enrolled 120 infants (58 massage; 62 control). At the end of the study, absolute NK cells were not different between the 2 groups; however, NK cytotoxicity was higher in the massage group, particularly among those who received ≥5 consecutive days of study intervention compared with control (13.79 vs 10 lytic units, respectively; P = .04). Infants in the massage group were heavier at end of study and had greater daily weight gain compared with those in the control group; other immunologic parameters, number of infections, and length of stay were not different between the 2 groups.

CONCLUSIONS

In this study, MT administered to stable preterm infants was associated with higher NK cytotoxicity and more daily weight gain. MT may improve the overall outcome of these infants. Larger studies are needed.

Tactile/kinesthetic stimulation (TKS) increases tibial speed of sound and urinary osteocalcin (U-MidOC and unOC) in premature infants (29-32weeks PMA)

Preterm delivery (<37 weeks post-menstrual age) is associated with suboptimal bone mass. We hypothesized that tactile/kinesthetic stimulation (TKS), a form of infant massage that incorporates kinesthetic movement, would increase bone strength and markers of bone accretion in preterm infants. Preterm, AGA infants (29-32 weeks) were randomly assigned to TKS (N=20) or Control (N=20). Twice daily TKS was provided 6 days per week for 2 weeks. Control infants received the same care without TKS treatment. Treatment was masked to parents, health care providers, and study personnel. Baseline and week two measures were collected for tibial speed of sound (tSOS, m/sec), a surrogate for bone strength, by quantitative ultrasound (Sunlight8000) and urine markers of bone metabolism, pyridinium crosslinks and osteocalcin (U-MidOC and unOC). Infant characteristics at birth and study entry as well as energy/nutrient intake were similar between TKS and Control. TKS intervention attenuated the decrease in tSOS observed in Control infants (p<0.05). Urinary pyridinium crosslinks decreased over time in both TKS and CTL (p<0.005). TKS infants experienced greater increases in urinary osteocalcin (U-MidOC, p<0.001 and unOC, p<0.05). We conclude that TKS improves bone strength in premature infants by attenuating the decrease that normally follows preterm birth. Further, biomarkers of bone metabolism suggest a modification in bone turnover in TKS infants in favor of bone accretion. Taken together, we speculate that TKS improves bone mineralization.

Incorporating speech-language pathology within Australian neonatal intensive care units

Working in neonatal intensive care units (NICU) is considered to be advanced practice for speech-language pathologists (SLPs) requiring post-graduate specialised education and ongoing clinical mentoring, not easily accessible within some countries such as Australia. This review investigated whether there was evidence to support SLPs as core NICU team members, rather than fleeting therapists. The review found that the roles and responsibilities of SLPs in NICUs included assessment and intervention of preterm infant communication, feeding and swallowing using a family-centred approach. This approach was respectful of the cultural and linguistic diversity of the parents and the particular expertise of other NICU team members. Whilst there has been a significant and promising increase in research with regard to SLP involvement with preterm infants (especially around feeding and swallowing assessment and specific treatments), the need for high-quality well-designed research is essential.

Gentle Human Touch and Yakson: The Effect on Preterm's Behavioral Reactions

Objective. Touch is one of the first strong positive senses that develop in neonate. Therapeutic touch could be considered as a complementary treatment in Neonate intensive care units (NICU). Methods. This quasi-experimental study was conducted to compare the effect of Yakson and GHT on behavioral reaction of preterm infants hospitalized in NICU in south-east of Iran. 90 preterm infants participated in this study. They are randomly divided into 3 groups: (1) Yakson group, n = 30, (2) GHT group, n = 30, (3) control group, n = 30. Each infant received the GHT and Yakson interventions twice a day for 5 days. Each session lasted 15 minutes. The control group received routine nursing care. Results. In interventional group, an increase was found in sleep state score after the Yakson and GHT intervention. Their awake and fussy states' scores decreased after both interventions. No significant difference was found between Yakson and GHT group in their behavioral state scores. Conclusion. The findings suggest that Yakson and GHT had soothing and calming effect on preterm infants and could be beneficial in nursing interventions.

Emprego de soluções adocicadas no alívio da dor neonatal em recém-nascido prematuro: uma revisão integrativa

As experiências dolorosas repetida em recém-nascidos podem ter efeito a curto e a longo prazo, especialmente nos prematuros. Como uma medida de alívio da dor, tem sido recomendado o uso de soluções adocicadas em procedimentos dolorosos. Este estudo objetiva avaliar as evidências do efeito da sacarose e da glicose oral no alívio da dor aguda em recém-nascidos prematuros. Realizou-se uma revisão integrativa, nas bases de dados MEDLINE e LILACS, no período de 2005 a 2010, foram selecionados oito artigos. A análise destes revelou o efeito analgésico da glicose e da sacarose em procedimentos agudos. Nenhum efeito colateral foi encontrado nos recém-nascidos que receberam a glicose/sacarose. Ressalta-se a importância do uso da escala de avaliação da dor que mais se identifique com a população predominante nas unidades neonatais, que seja de fácil aplicação e manuseio pelos profissionais de saúde.

Effect of osteopathic manipulative treatment on gastrointestinal function and length of stay of preterm infants: an exploratory study

Background

Organizational improvement of neonatal intensive care units requires strict monitoring of preterm infants, including routine assessment of physiological functions of the gastrointestinal system and optimized procedures for the definition of appropriate discharge timing.

Methods

We conducted a prospective study on the effect of osteopathic manipulative treatment in a cohort of N = 350 consecutive premature infants admitted to a neonatal intensive care unit without any major complication between 2005 and 2008. In addition to ordinary care, N = 162 subjects received osteopathic treatment. Endpoints of the study were differences between study and control groups in terms of excessive length of stay and gastrointestinal symptoms, defined as the upper quartiles in the distribution of the overall population. Statistical analysis was based on crude and adjusted odds ratios from multivariate logistic regression.

Results

Baseline characteristics were evenly distributed across treated/control groups, except for the rate of infants unable to be oral fed at admission, significantly higher among those undergoing osteopathic care (p = .03). Osteopathic treatment was significantly associated with a reduced risk of an average daily occurrence of gut symptoms per subject above .44 (OR = 0.45; 0.26-0.74). Gestational age lower or equal to 32 weeks, birth weight lower or equal to 1700 grams and no milk consumption at admission were associated with higher rates of length of stay in the unit of at least 28 days, while osteopathic treatment significantly reduced such risk (OR = 0.22;0.09-0.51).

Conclusions

In a population of premature infants, osteopathic manipulative treatment showed to reduce a high occurrence of gastrointestinal symptoms and an excessive length of stay in the NICU. Randomized control studies are needed to generalize these results to a broad population of high risk newborns.

Exploring the Role of Touch in the First Year of Life: Mothers' Perspectives of Tactile Interactions with Their Infants

Introduction:

Touch is a basic instinctual interaction between a parent and his or her infant and has a vital role in the infant's early development. Parents provide a variety of tactile stimulation while addressing their infant's daily care routines. This paper reports on research findings, exploring the nature of this tactile interaction and how it is influenced by personal and contextual factors.

Method:

A qualitative study, employing a phenomenological approach, was conducted to explore the experiential nature of tactile interaction. Data were collected from six mothers of typically developing infants through single semi-structured interviews, and analysed thematically. Credibility and trustworthiness were addressed throughout the research process through peer checking, an audit trail and the completion of a reflexive diary.

Findings:

The mothers described the importance of tactile interaction as a medium through which to bond with their infant and also discussed the influence that the infant's development has on this dyadic relationship. Personal and contextual factors were identified as affecting engagement in tactile interaction.

Conclusion:

Based on these findings, recommendations are made for occupational therapists who work with infants. The consideration of personal and contextual factors that influence mother-infant tactile interaction will contribute to a family-centred approach to therapy and support the achievement of best practice in this area.

Preterm infant massage therapy research: a review

In this paper, preterm infant massage therapy studies are reviewed. Massage therapy has led to weight gain in preterm infants when moderate pressure massage was provided. In studies on passive movement of the limbs, preterm infants also gained significantly more weight, and their bone density also increased. Research on ways of delivering the massage is also explored including using mothers versus therapists and the added effects of using oils. The use of mothers as therapists was effective in at least one study. The use of oils including coconut oil and safflower oil enhanced the average weight gain, and the transcutaneous absorption of oil also increased triglycerides. In addition, the use of synthetic oil increased vagal activity, which may indirectly contribute to weight gain. The weight gain was associated with shorter hospital stays and, thereby, significant hospital cost savings. Despite these benefits, preterm infant massage is only practiced in 38% of neonatal intensive care units. This may relate to the underlying mechanisms not being well understood. The increases noted in vagal activity, gastric motility, insulin and IGF-1 levels following moderate pressure massage are potential underlying mechanisms. However, those variables combined do not explain all of the variance in weight gain, highlighting the need for additional mechanism studies.

Touch and massage for medically fragile infants

Research investigating the efficacy of infant massage has largely focused on premature and low birth weight infants. The majority of investigations have neglected highly acute patients in academic neonatal intensive care units (NICUs). The current study was developed with two aims: (Phase 1) to develop, implement and demonstrate the feasibility and safety of a parent-trained compassionate touch/massage program for infants with complex medical conditions and (Phase 2) to conduct a longitudinal randomized control trial (RCT) of hand containment/massage versus standard of care in a level III academic Center for Newborn and Infant Critical Care (CNICC). Certified infant massage instructors (CIMIs) taught parents to massage their hospitalized infants. Massage therapy and instruction were performed for seven consecutive days and health outcomes were collected for up to 1 month following treatment. Caregivers, nurses and certified infant massage therapists indicated moderate to high levels of satisfaction and feasibility with the implementation of hand containment/massage in a level III academic center CNICC. In addition, infant behavioral and physiological measures were within safe limits during the massage sessions. All caregivers participating in the massage group reported high levels of satisfaction 7 days into the intervention and at the 1-month follow-up with regards to their relationship with their infant, the massage program's impact on that relationship and the massage program. Due to unequal and small sample sizes, between group analyses (control versus massage) were not conducted. Descriptive infant characteristics of health outcomes are described. Preliminary data from this study indicates feasibility and safety of infant massage and satisfaction among the caregivers, CIMIs and the nurses in the CNICC. An important contribution from this study was the demonstration of the infants' safety based on physiological stability and no change in agitation/pain scores of the infants receiving massage. Massage in a tertiary urban academic NICU continues to be an area of needed study. Future studies examining infant health outcomes, such as weight gain, decreased length of hospitalization and caregiver-infant bonding, would provide greater insight into the impact of massage for medically fragile infants.

Directions and dilemmas in massage therapy research: a workshop report from the 2009 north american research conference on complementary and integrative medicine

BACKGROUND

Massage therapy (MT) is widely used and expanding rapidly, but systematic research on its mechanisms and effects has, in contrast with many other therapeutic fields, a short history.

PURPOSE

To take stock of the current state of MT research and to explore approaches, directions, and strategies with the potential to make the next two decades of MT research optimally productive.

SETTING

The 2009 North American Research Conference on Complementary and Integrative Medicine held in Minneapolis, Minnesota.

METHOD

Using a modified Delphi method, the study authors led an interactive workshop that aimed to identify established MT research findings, needed MT research, weaknesses and limitations in currently available MT research, and directions to pursue in the next two decades of MT research.

PARTICIPANTS

The thirty-seven conference attendees-including MT researchers, educators, and practitioners, and other health care practitioners who already work interprofessionally with MT-actively participated in the workshop and ensured that a diversity of perspectives were represented.

RESULTS

The MT field has made rapid and laudable progress in its short history, but at the same time this short history is probably the main reason for most of the current shortcomings in MT research. Drawing on a diversity of backgrounds, workshop participants identified many opportunities and strategies for future research.

CONCLUSION

Though lost time can never be recovered, the field's late start in research should not be allowed to be a demoralizing handicap to progress. Modern scientific methods and technologies, applied to the range of directions and dilemmas highlighted in this report, can lead to impressive progress in the next twenty years of MT research.

Massage accelerates brain development and the maturation of visual function

Environmental enrichment (EE) was shown recently to accelerate brain development in rodents. Increased levels of maternal care, and particularly tactile stimulation through licking and grooming, may represent a key component in the early phases of EE. We hypothesized that enriching the environment in terms of body massage may thus accelerate brain development in infants. We explored the effects of body massage in preterm infants and found that massage accelerates the maturation of electroencephalographic activity and of visual function, in particular visual acuity. In massaged infants, we found higher levels of blood IGF-1. Massage accelerated the maturation of visual function also in rat pups and increased the level of IGF-1 in the cortex. Antagonizing IGF-1 action by means of systemic injections of the IGF-1 antagonist JB1 blocked the effects of massage in rat pups. These results demonstrate that massage has an influence on brain development and in particular on visual development and suggest that its effects are mediated by specific endogenous factors such as IGF-1.

Salivary cortisol and behavioral state responses of healthy newborn infants to tactile-only and multisensory interventions

OBJECTIVE

To compare changes in stress reactivity (measured via the biomarker salivary cortisol) and behavioral state in healthy newborn infants immediately following 1 of 2 interventions: (1) tactile-only stimulation or (2) a multisensory, auditory, tactile, visual, and vestibular stimulation with a control group.

DESIGN

A randomized prospective design pilot study.

SETTING

Normal newborn nurseries of 2 midwestern perinatal centers.

PARTICIPANTS

Forty healthy newborn infants receiving standard nursing care.

METHODS

Infants were randomly assigned to receive 15 minutes of tactile-only, auditory, tactile, visual, and vestibular, or no stimulation 30 minutes before feeding. Saliva samples were collected before, immediately following, and 10 minutes postintervention. Behavioral state was judged every minute.

RESULTS

Tactile-only group infants had the largest increase in cortisol levels, followed by control group infants. In contrast, infants who received the multisensory intervention showed a significant steady decline in cortisol. Asleep was the predominant state for all 3 groups and cry was minimal.

CONCLUSIONS

Tactile-only stimulation may increase infant stress reactivity while the benefit of the multisensory auditory, tactile, visual, and vestibular intervention may be in the reduction of infant stress reactivity. Interventions appeared to have minimal effect on stress reactivity based on behavioral state.

Massage with kinesthetic stimulation improves weight gain in preterm infants

OBJECTIVE

The aim of this study was to evaluate the effects of massage with or without kinesthetic stimulation on weight gain and length of hospital stay in the preterm infant.

STUDY DESIGN

A prospective randomized clinical trial was conducted evaluating the effects of massage with or without kinesthetic stimulation (KS) on weight gain and length of stay (LOS) in medically stable premature (<1500 g and/or <or=32 weeks gestational age) neonates. Infants were randomized either to receive no intervention (control), massage therapy alone (massage), or massage therapy with KS (M/KS). Linear regression analysis was performed to evaluate differences in the primary outcomes between the groups after controlling for covariates. Post hoc analysis with stratification by birthweight (BW> and <1000 g) was also performed.

RESULT

A total of 60 premature infants were recruited for this study; 20 infants in each group. Average daily weight gain and LOS were similar between the groups after controlling for covariates. For infants with BW>1000 g, average daily weight gain was increased in the intervention groups compared to control. This effect was mainly attributable to the M/KS group.

CONCLUSION

Massage with KS is a relatively simple and inexpensive intervention that can improve weight gain in selected preterm infants. Length of hospital stay is not impacted by massage with or without KS. Further studies are needed to evaluate the effect of massage in the extremely low BW(<1000 g) infant.

American Academy of Pediatrics. The use of complementary and alternative medicine in pediatrics

The American Academy of Pediatrics is dedicated to optimizing the well-being of children and advancing family-centered health care. Related to these goals, the American Academy of Pediatrics recognizes the increasing use of complementary and alternative medicine in children and, as a result, the need to provide information and support for pediatricians. From 2000 to 2002, the American Academy of Pediatrics convened and charged the Task Force on Complementary and Alternative Medicine to address issues related to the use of complementary and alternative medicine in children and to develop resources to educate physicians, patients, and families. One of these resources is this report describing complementary and alternative medicine services, current levels of utilization and financial expenditures, and associated legal and ethical considerations. The subject of complementary and alternative medicine is large and diverse, and consequently, an in-depth discussion of each method of complementary and alternative medicine is beyond the scope of this report. Instead, this report will define terms; describe epidemiology; outline common types of complementary and alternative medicine therapies; review medicolegal, ethical, and research implications; review education and training for complementary and alternative medicine providers; provide resources for learning more about complementary and alternative medicine; and suggest communication strategies to use when discussing complementary and alternative medicine with patients and families.

Effect of Yakson and Gentle Human Touch versus usual care on urine stress hormones and behaviors in preterm infants: a quasi-experimental study

BACKGROUND

Touching, one of the most developed senses, is proven to relax preterm infants. Yakson is a Korean touching method for healing and relaxation similar to Gentle Human Touch (GHT), which is used in the United States.

OBJECTIVE

The goal of this study was to test the effect of Yakson and GHT on preterm infants' stress and behaviors compared to usual nursing care.

DESIGN

A quasi-experimental study design was used.

PARTICIPANTS

Fifty-nine preterm infants (26-34 weeks gestational age) in the neonatal intensive care unit were chronologically assigned into three groups; Yakson (n=20), GHT (n=20), and control group (n=19).

METHODS

The Yakson and GHT groups each received an intervention for 15min twice a day for 15 days while the control group received usual nursing care. Yakson consists of three five-minute phases: resting the hand on the infant, gentle caressing, and resting the hand again. GHT consists of hand resting for 15min. Twenty-four-hour urine cortisol and norepinephrine samples were collected both before and after the 15-day intervention period. The infants' sleep and awake states were observed before, during, and after each intervention.

RESULTS

Following the intervention period, preterm infants in the Yakson and GHT groups had significantly lower stress hormone levels compared to the control group preterm infants. No significant difference was found in stress hormone levels between Yakson and GHT group preterm infants. After Yakson or GHT, the infants exhibited an increased percentage of sleep states and a decreased percentage of awake and fussy states.

CONCLUSIONS

The findings suggest that Yakson is another touching method that is not aversive or stressful to preterm infants, and which may provide several positive effects on preterm infants.

Effect of skin barrier therapy on neonatal mortality rates in preterm infants in Bangladesh: a randomized, controlled, clinical trial

OBJECTIVE

Skin barrier therapy during the neonatal period, when the skin barrier is most highly compromised and the risk of death is greatest, has been shown to have a number of potential benefits, including reduced risk of nosocomial sepsis. Topical application of emollients that augment skin barrier function was evaluated as a strategy for improving survival rates among hospitalized preterm infants in Bangladesh.

METHODS

A prospective, randomized, controlled, clinical trial was conducted in the special care nursery at Dhaka Shishu (Children) Hospital, the largest tertiary care children's hospital in Bangladesh. Preterm infants (gestational age: < or = 33 weeks; N = 497) received daily topical applications of sunflower seed oil or Aquaphor ointment. Neonatal mortality rates were compared in an intent-to-treat analysis with a control group that did not receive emollient therapy.

RESULTS

Treatment with sunflower seed oil resulted in a statistically significant 26% reduction in mortality rates, compared with infants not receiving topical emollient therapy. Aquaphor therapy also significantly reduced mortality rates, by 32%.

CONCLUSIONS

Topical therapy with skin barrier-enhancing emollients improved survival rates among preterm hospitalized infants in Bangladesh. This study provides strong evidence for the implementation of topical therapy for high-risk preterm neonates in developing countries.

Energy expenditure in growing preterm infants receiving massage therapy

OBJECTIVE

Massage therapy has been consistently shown to increase weight gain in preterm infants. The mechanism of this presumed improved metabolic efficiency is unknown. We conducted the following trial to test the hypothesis that massage therapy reduces energy expenditure in growing healthy preterm infants.

STUDY DESIGN

A prospective, randomized, cross-over design study was conducted in 10 healthy, appropriate weights for gestational age, gavage fed preterm infants. Each infant was studied twice: after a period of either 5 days of massage therapy, or after a period of 5 days without massage therapy. Infants were randomized to 5 days of massage followed by 5 days of no massage (n = 5) or the opposite sequence (n = 5). During the massage therapy period, massage was provided daily for three 15 minute periods at the beginning of each 3 hour period every morning. Metabolic measurements were performed by indirect calorimetry, using the Deltatrac II Metabolic cart.

RESULTS

Energy expenditure was significantly lower in infants after the 5 day massage therapy period (59.6 +/- 3.6 Kcal/Kg/ 24 hours) than after the period without (63.1 +/- 5.4 Kcal/Kg/ 24 hours) (p = 0.05).

CONCLUSIONS

Energy expenditure is significantly lowered by 5 days of massage therapy in metabolically and thermally stable preterm infants. This decrease in energy expenditure may be in part responsible for the enhanced growth caused by massage therapy.

Prophylactic role for complementary and alternative medicine in perinatal programming of adult health

BACKGROUND

The health status of an individual in adulthood is proposed to be determined by events occurring in the prenatal and early postnatal period. A common early life event proven to have long lasting effects on the developing fetus is stress, including pain. Exposure of fetal and neonatal infants to repetitive psychological (e.g., maternal stress) or physiological (e.g., pain, infection, and noise) stress during this period is proposed to alter mechanisms involved in the regulation of stress, immunological maturation, pain perception, and cognition. Such changes, which persist into adulthood, may occur via alterations in the development of the hypothalamic-pituitary-adrenal (HPA) axis. This process is typically referred to as 'perinatal programming'. Ontogenic alterations in the development of the HPA-axis have been related to a number of adult pathologies such as cardiovascular disease, type 2 diabetes, asthma, as well as psychopathologies such as anxiety and depression.

OBJECTIVE

In this review, the effectiveness of complementary and alternative medicine (CAM), such as music, dietary supplements, massage and aromatherapy, in reducing perinatal stress in mothers and infants is examined. An emphasis is placed on these therapies as preventative measures which may be of value to individuals at risk of developing disease profiles associated with the consequences of adverse perinatal programming. The widening interest in perinatal programming and CAM suggests the potential for CAM to become a valuable tool in offsetting negative adult health outcomes resulting from perinatal programming associated with adverse gestational early life environments.

Physical activity programs for promoting bone mineralization and growth in preterm infants

BACKGROUND

Lack of physical stimulation may contribute to metabolic bone disease of preterm infants resulting in poor bone mineralization and growth. Physical activity programs in the presence of adequate nutrition might help to promote bone mineralization and growth.

OBJECTIVES

The primary objective of this review was to assess whether physical activity programs in preterm infants improve bone mineralization and growth and reduce the risk of fractures.

SEARCH STRATEGY

Following the standard search strategy of the Cochrane Neonatal Review Group, a search was conducted in September 2006 including PubMed, EMBASE, CINAHL, the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 3, 2006), cross-references and handsearching of abstracts of the Society for Pediatric Research and the International Journal of Sports Medicine. No language restrictions were applied.

SELECTION CRITERIA

Randomized and quasi-randomized controlled trials comparing physical activity programs (extension and flexion, range-of-motion exercises for several minutes a day several days per week for at least two weeks) to no organized physical activity programs in preterm infants. Eligible studies included those that provided physical activity for the experimental group, with or without massage and/or tactile stimulation for both experimental and control groups, as well as information on at least one outcome of interest.

DATA COLLECTION AND ANALYSIS

Two review authors independently performed searches and extracted data. All three review authors were involved in selection and assessment of quality of studies. The statistical methods included relative risk (RR), risk difference (RD) and number needed to treat (NNT) for dichotomous outcomes and weighted mean difference (WMD) for continuous outcomes, reported with 95% confidence intervals (CI). Heterogeneity was estimated by the I(2) statistic. A fixed effect model was used to pool data for meta-analyses.

MAIN RESULTS

Six trials enrolling 169 preterm infants (gestational age 26 to 34 weeks) were included in this review. All were small (N = 20 - 49) single center studies evaluating daily physical activity for 3.5 to 4 weeks during initial hospitalization. The methodological quality and reporting of all trials was poor. None of them stated the methods of concealment of patient allocation, the method of randomization or attempted blinding of the intervention. Only two trials attempted blinding of outcome assessors for outcomes relevant to this review. Two trials (N = 55) demonstrated moderate short-term benefits of physical activity on bone mineralization at completion of the physical activity program. Data was not pooled for meta-analyses due to methodological differences. The only trial (N = 20) assessing long-term effects on bone mineralization showed no effect of physical activity administered during initial hospitalization on bone mineralization at 12 months corrected age. Meta-analysis from three trials (N = 78) demonstrated an effect of physical activity on daily weight gain (WMD 2.77 g/kg/d, 95% CI 1.62, 3.92). Data from two trials (N = 58) showed no effect on linear growth (WMD -0.04 cm/week, 95% CI -0.19, 0.11) or head growth (WMD -0.03 cm/week, 95% CI -0.14, 0.09) during the study period. The I(2) statistic suggested heterogeneity on the analysis of linear growth (p = 0.006, I(2) = 86.9%). None of the trials assessed fractures or other outcomes relevant to this review. Data was insufficient for subgroup analyses based on birth weight and calcium/phosphorus intake.

AUTHORS' CONCLUSIONS

There is weak evidence from six small randomized trials of poor methodological and reporting quality that physical activity programs might promote moderate short-term weight gain and bone mineralization in preterm infants. The clinical importance of these findings is questionable given the small effect size and low baseline risk of poor bone mineralization and growth in study participants. Data is inadequate to assess harm or long term effects. Current evidence does not justify the standard use of physical activity programs in preterm infants. Further evaluation of this intervention in well designed trials incorporating extremely low birth weight infants who are at high risk of osteopenia is required. Future trials should report on adverse events and long term outcomes including fractures, growth, bone mineralization, skeletal deformities and neurodevelopmental impairment. These trials should address the possibility that nutritional intake (calories, protein, calcium, phosphorus) might modify the effects of physical activity.

Randomized controlled trials of pediatric massage: a review

The existing reviews of massage therapy (MT) research are either limited to infants, adults, or were conducted prior to the publication of the most recent studies using pediatric samples. Randomized controlled trials (RCTs) of pediatric MT are reviewed. A literature search yielded 24 RCTs of pediatric MT, defined as the manual manipulation of soft tissue intended to promote health and well-being in recipients between 2 and 19 years of age. Because RCTs of pediatric MT varied considerably in the amount and types of data reported, quantitative and narrative review methods were both used. Single-dose and multiple-dose effects were examined separately. Among single-dose effects, significant reductions of state anxiety were observed at the first session (g = 0.59, P < 0.05) and the last session (g = 1.10, P < 0.01) of a course of treatment. Effects for salivary cortisol (g = 0.28), negative mood (g = 0.52) and behavior (g = 0.37) were non-significant. Three of eleven multiple-dose effects were statistically significant. These were trait anxiety (g = 0.94, P < 0.05), muscle tone (g = 0.90, P < 0.01) and arthritis pain (g = 1.33, P < 0.01). Results of studies not permitting effect size calculation were judged to be generally consistent with quantitative results. MT benefits pediatric recipients, though not as universally as sometimes reported. Numerous weaknesses endemic to MT research (e.g. low statistical power, frequent failure to report basic descriptive statistics) are identified, and recommendations for future pediatric MT research are discussed.

Massage intervention for promoting mental and physical health in infants aged under six months

BACKGROUND

Infant massage is increasingly being used in the community for low-risk babies and their primary care givers. Anecdotal claims suggest benefits for sleep, respiration, elimination and the reduction of colic and wind. Infant massage is also thought to reduce infant stress and promote positive parent-infant interaction.

OBJECTIVES

The aim of this review was to assess the effectiveness of infant massage in promoting infant physical and mental health in population samples.

SEARCH STRATEGY

Searches were undertaken of CENTRAL 2005 (Issue 3), MEDLINE (1970 to 2005), PsycINFO (1970 to 2005), CINAHL (1982 to 2005), EMBASE (1980 to 2005), and a number of other Western and Chinese databases.

SELECTION CRITERIA

Studies in which babies under the age of six months were randomised to an infant massage or a no-treatment control group, and utilising a standardised outcome measuring infant mental or physical development.

DATA COLLECTION AND ANALYSIS

Weighted and standardised mean differences and 95% confidence intervals are presented. Where appropriate the results have been combined in a meta-analysis using a random effects model.

MAIN RESULTS

Twenty-three studies were included in the review. One was a follow-up study and thirteen were included in a separate analysis due to concerns about the uniformly significant results and the lack of dropout. The results of nine studies providing primary data suggest that infant massage has no effect on growth, but provides some evidence suggestive of improved mother-infant interaction, sleep and relaxation, reduced crying and a beneficial impact on a number of hormones controlling stress. Results showing a significant impact on number of illnesses and clinic visits were limited to a study of Korean orphanage infants. There was no evidence of effects on cognitive and behavioural outcomes, infant attachment or temperament. The data from the 13 studies regarded to be at high risk of bias show uniformly significant benefits on growth, sleep, crying and bilirubin levels.

AUTHORS' CONCLUSIONS

The only evidence of a significant impact of massage on growth was obtained from a group of studies regarded to be at high risk of bias. There was, however, some evidence of benefits on mother-infant interaction, sleeping and crying, and on hormones influencing stress levels. In the absence of evidence of harm, these findings may be sufficient to support the use of infant massage in the community, particularly in contexts where infant stimulation is poor. Further research is needed, however, before it will be possible to recommend universal provision.

Rehabilitation of medical and acute care patients

Cancer and serious systemic illness result in several physiologic changes that involve multiple body systems. While the primary conditions are addressed with traditional modalities of medicine, the side effects, secondary changes, and complications can be ameliorated or even prevented with rehabilitation and supportive care. This article reviews problems facing the oncologic and critically ill animal, discusses basic techniques in the management of these animals, and highlights the essential role of rehabilitation in obtaining maximal functional capacity in the critically ill patient.

Vagal activity, gastric motility, and weight gain in massaged preterm neonates

OBJECTIVE

Multiple studies have documented an increase in weight gain after 5 to 10 days of massage therapy for preterm neonates. The massaged preterm neonates did not consume more calories than the control neonates. One potential mechanism for these effects might involve massage-induced increases in vagal activity, which in turn may lead to increased gastric motility and thereby weight gain.

STUDY DESIGN

The present randomized study explored this potential underlying mechanism by assessing gastric motility and sympathetic and parasympathetic nervous system activity in response to massage therapy (moderate pressure) versus sham massage (light pressure) and control conditions in a group of preterm neonates.

RESULTS

Compared with preterm neonates receiving sham massage, preterm neonates receiving massage therapy exhibited greater weight gain and increased vagal tone and gastric motility during and immediately after treatment. Gastric motility and vagal tone during massage therapy were significantly related to weight gain.

CONCLUSION

The weight gain experienced by preterm neonates receiving moderate-pressure massage therapy may be mediated by increased vagal activity and gastric motility.

Massage for promoting growth and development of preterm and/or low birth-weight infants

BACKGROUND

It has been argued that infants in Neonatal Intensive Care Units are subject both to a highly stressful environment - continuous, high-intensity noise and bright light - and to a lack of the tactile stimulation that they would otherwise experience in the womb or in general mothering care. As massage seems to both decrease stress and provide tactile stimulation, it has been recommended as an intervention to promote growth and development of preterm and low-birth weight infants.

OBJECTIVES

To determine whether preterm and/or low birth-weight infants exposed to massage experience improved weight gain and earlier discharge compared to infants receiving standard care; to determine whether massage has any other beneficial or harmful effects on this population.

SEARCH STRATEGY

The following databases were searched: the specialized register of the Cochrane Neonatal Review Group and that of the Cochrane Complementary Medicine Field. Searches were also undertaken of the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 3, 2003), MEDLINE, EMBASE, Psychlit, CINAHL and Dissertation Abstracts International (up to July 1, 2003). Further references were obtained by citation tracking, checking personal files and by correspondence with appropriate experts. Data provided in published reports was supplemented by information obtained by correspondence with authors. There were no language restrictions.

SELECTION CRITERIA

Randomised trials in which infants with gestational age at birth <37 weeks or weight at birth <2500g received systematic tactile stimulation by human hands. At least one outcome assessing weight gain, length of stay, behaviour or development must be reported.

DATA COLLECTION AND ANALYSIS

Data extracted from each trial were baseline characteristics of sample, weight gain, length of stay and behavioural and developmental outcomes. Physiological and biochemical outcomes were not recorded. Data were extracted by three reviewers independently. Statistical analysis was conducted using the standard Cochrane Collaboration methods.

MAIN RESULTS

Massage interventions improved daily weight gain by 5.1g (95% CI 3.5, 6.7g). There is no evidence that gentle, still touch is of benefit (increase in daily weight gain 0.2g; 95% CI -1.2, 1.6g). Massage interventions also appeared to reduce length of stay by 4.5 days (95% CI 2.4, 6.5) though there are methodological concerns about the blinding of this outcome. There was also some evidence that massage interventions have a slight, positive effect on postnatal complications and weight at 4 - 6 months. However, serious concerns about the methodological quality of the included studies, particularly with respect to selective reporting of outcomes, weaken credibility in these findings.

REVIEWERS' CONCLUSIONS

Evidence that massage for preterm infants is of benefit for developmental outcomes is weak and does not warrant wider use of preterm infant massage. Where massage is currently provided by nurses, consideration should be given as to whether this is a cost-effective use of time. Future research should assess the effects of massage interventions on clinical outcome measures, such as medical complications or length of stay, and on process-of-care outcomes, such as care-giver or parental satisfaction.

Kinesthetic stimulation for preventing apnea in preterm infants

BACKGROUND

Recurrent apnea is common in preterm infants, particularly at very early gestational ages. These episodes of loss of effective breathing can lead to hypoxemia and bradycardia, which may be severe enough to require resuscitation including use of positive pressure ventilation or other treatments. Physical stimulation is often used to restart breathing and it is possible that repeated stimulation, such as with an oscillating mattress (kinesthetic stimulation), might prevent apnea and its consequences.

OBJECTIVES

In preterm infants at risk for apnea, does prophylactic use of kinesthetic stimulation lead to a clinically important reduction in apnea and bradycardia, and use of intemittent positive preswsure ventilation (IPPV).

SEARCH STRATEGY

The standard search strategy of the Neonatal Review Group was used. This included searches of the Oxford Database of Perinatal trials, Cochrane Controlled Trials Register, MEDLINE, previous reviews including cross references, abstracts, conferences and symposia proceedings, expert informants, journal handsearching mainly in the English language.

SELECTION CRITERIA

All trials in preterm infants at risk of developing clinical apnea which utilised random or quasi-random allocation to treatment with an oscillating mattress or control, were eligible.

DATA COLLECTION AND ANALYSIS

Standard methods of the Cochrane Collaboration and its Neonatal Review Group were used with separate evaluation of trial quality and data extraction by each author and synthesis of the data using relative risk.

MAIN RESULTS

There were no differences in short term effects (apnea /bradycardia, IVH, use of IPPV, sleep/wake cycles and neurological status at discharge) or longterm effects (in one trial - growth and development to one year).

REVIEWER'S CONCLUSIONS

Implications for practice. Prophylactic use of kinesthetic stimulation cannot be recommended to reduce apnea/bradycardia in preterm infants. Implications for research. There are currently no clear research questions regarding prophylactic use of kinesthetic stimulation to prevent apnea in preterm infants.
