You will be provided with the titles and abstracts of a collection of medical RCT reports studying a clinical question -- for instance, the efficacy of an intervention on some medical outcome. Please write a few sentences synthesizing the findings of these reports, which could serve as a conclusion section for a systematic review article. Your response should not include any other text. The RCT reports are below.



Title 1:
Labor pain is reduced by massage therapy.
Abstract 1:
Twenty-eight women were recruited from prenatal classes and randomly assigned to receive massage in addition to coaching in breathing from their partners during labor, or to receive coaching in breathing alone (a technique learned during prenatal classes). The massaged mothers reported a decrease in depressed mood, anxiety and pain, and showed less agitated activity and anxiety and more positive affect following the first massage during labor. In addition, the massaged mothers had significantly shorter labors, a shorter hospital stay and less postpartum depression.


Title 2:
Comparison between massage and music therapies to relieve the severity of labor pain.
Abstract 2:
During labor, women experience a high level of intense, stressful and steady pain that may negatively affect both mothers and neonates. Painkillers have previously been used for childbearing women, but nowadays, owing to some well-known limitations and serious side effects, nonpharmacologic methods such as massage and music therapies are being broadly recommended. The present clinical trial was conducted to compare the effects of massage and music therapies on the severity of labor pain in the Ilam province of western Iran.
                Overall, 101 primigravidae who were hospitalized for vaginal delivery were recruited and randomly stratified into two groups of either massage (n = 51) or music (n = 50) therapies. Pain was measured using the visual analog scale and the two groups were compared in terms of pain severity before and after the interventions.
                Mothers in the massage therapy group had a lower level of pain compared with those in the music therapy group (p = 0.009). A significant difference was observed between the two groups in terms of pain severity after intervention (p = 0.01). Agonizing, or most severe, labor pain was significantly relieved after massage therapy (p = 0.001).
                Massage therapy was an effective method for reducing and relieving labor pain compared with music therapy and can be clinically recommended as an alternative, safe and affordable method of pain relief where using either pharmacological or nonpharmacological methods are optional.


Title 3:
Massage or music for pain relief in labour: a pilot randomised placebo controlled trial.
Abstract 3:
Research on massage therapy for maternal pain and anxiety in labour is currently limited to four small trials. Each used different massage techniques, at different frequencies and durations, and relaxation techniques were included in three trials. Given the need to investigate massage interventions that complement maternal neurophysiological adaptations to labour and birth pain(s), we designed a pilot randomised controlled trial (RCT) to test the effects of a massage programme practised during physiological changes in pain threshold, from late pregnancy to birth, on women's reported pain, measured by a visual analogue scale (VAS) at 90 min following birth. To control for the potential bias of the possible effects of support offered within preparation for the intervention group, the study included 3 arms--intervention (massage programme with relaxation techniques), placebo (music with relaxation techniques) and control (usual care). The placebo offered a non-pharmacological coping strategy, to ensure that use of massage was the only difference between intervention and placebo groups. There was a trend towards slightly lower mean pain scores in the intervention group but these differences were not statistically significant. No differences were found in use of pharmacological analgesia, need for augmentation or mode of delivery. There was a trend towards more positive views of labour preparedness and sense of control in the intervention and placebo groups, compared with the control group. These findings suggest that regular massage with relaxation techniques from late pregnancy to birth is an acceptable coping strategy that merits a large trial with sufficient power to detect differences in reported pain as a primary outcome measure.


Title 4:
Effects of massage on pain and anxiety during labour: a randomized controlled trial in Taiwan.
Abstract 4:
To investigate the effects of massage on pain reaction and anxiety during labour.
                Labour pain is a challenging issue for nurses designing intervention protocols. Massage is an ancient technique that has been widely employed during labour, however, relatively little study has been undertaken examining the effects of massage on women in labour.
                A randomized controlled study was conducted between September 1999 and January 2000. Sixty primiparous women expected to have a normal childbirth at a regional hospital in southern Taiwan were randomly assigned to either the experimental (n=30) or the control (n=30) group. The experimental group received massage intervention whereas the control group did not. The nurse-rated present behavioural intensity (PBI) was used as a measure of labour pain. Anxiety was measured with the visual analogue scale for anxiety (VASA). The intensity of pain and anxiety between the two groups was compared in the latent phase (cervix dilated 3-4 cm), active phase (5-7 cm) and transitional phase (8-10 cm).
                In both groups, there was a relatively steady increase in pain intensity and anxiety level as labour progressed. A t-test demonstrated that the experimental group had significantly lower pain reactions in the latent, active and transitional phases. Anxiety levels were only significantly different between the two groups in the latent phase. Twenty-six of the 30 (87%) experimental group subjects reported that massage was helpful, providing pain relief and psychological support during labour.
                Findings suggest that massage is a cost-effective nursing intervention that can decrease pain and anxiety during labour, and partners' participation in massage can positively influence the quality of women's birth experiences.
Massage may have a role in reducing pain, and improving women's emotional experience of labour. However, there is a need for further research.
