Increasing Warmth in Adolescents with Anorexia Nervosa: A Randomized Controlled Crossover Trial Examining the Efficacy of Mustard and Ginger Footbaths.

OBJECTIVE: To analyze the thermogenic effects of footbaths with medicinal powders in adolescents with anorexia nervosa (AN) in comparison to healthy controls (HCs). Intervention and Outcomes. Forty-one female participants (21 AN, 20 HCs; 14.22 ± 1.54 years) received three footbaths-warm water and mustard (MU, Sinapis nigra), warm water and ginger (GI, Zingiber officinale), or warm water only (WA), in random order within a crossover design. Data were collected before (t1), immediately after foot immersion (maximum 20 minutes) (t2), and after 10 minutes subsequently (t3). Actual skin temperature (high resolution thermography) and perceived warmth (HeWEF questionnaire) were assessed at each time point for various body parts. The primary outcome measure was self-perceived warmth at the feet at t3. Secondary outcome measures were objective skin temperature and subjective warmth at the face, hands, and feet. RESULTS: Perceived warmth at the feet at t3 was significantly higher after GI compared to WA (mean difference -1.02) and MU (-1.07), with no differences between those with AN and HC (-0.29). For the secondary outcome measures, a craniocaudal temperature gradient for the skin temperature (thermography) was noted at t1 for patients with AN and HC (AN with colder feet). The craniocaudal gradient for subjective warmth was only seen for patients with AN. CONCLUSION: Footbaths with ginger increased warmth perception at the feet longer than with mustard or warm water only for adolescents with AN as well as for HC. The impact of ginger footbaths on recovery of thermoregulatory disturbances in patients with AN repeated over extended periods merits further investigation.

Physiological and emotional effects of pentatonic live music played for preterm neonates and their mothers in the Newborn Intensive Care Unit: A randomized controlled trial.

OBJECTIVE: Despite attempts to increase calmness in the Newborn Intensive Care Unit (NICU), preterm neonates still experience stress. The question arises how to further promote the infants' wellbeing. Therefore, the immediate effects of pentatonic live music on preterm infants and their mothers were examined. DESIGN AND METHODS: In a two-centre randomized controlled trial with crossover design preterm infants were exposed sequentially to two conditions: live pentatonic harp music (LPHM) used in Anthroposophic Medicine or standard care. The order of the conditions was randomized within each subject. The primary outcome was change of the number of oxygen desaturations < 90%/h, whereas secondary outcomes were: heart rate, respiratory rate, oxygen saturation, heart rate variability (HRV), the perfusion index, pulse-transit-time and maternal anxiety and others not reported on in this article. RESULTS: 21 preterm infants were randomized (14 girls), mean gestational age at measurement 35 + 0 weeks (SD 1 week). The primary outcome parameter showed no significant changes. Regarding the secondary outcomes the comparison of the pre-post-differences between the conditions showed significant effects for the HRV parameters pNN50 (ΔpNN50 = 1.46%, z = -2.47, p = .001) and SDNN (ΔSDNN=-0.06 ms, z = -2.25, p = .002). The music intervention significantly increased the values of pNN50 (Mdn 1.2% vs. 2.6%, p = 0.04) and marginally those of SDNN (Mdn 31.7 ms vs. 36.4 ms, p = 0.05). No changes were found in the other parameters. CONCLUSIONS: While the use of music in the NICU had no effect on the number of oxygen desaturations, it increased two HRV parameters indicative of infants' parasympathetic tone.

Effects of Footbaths with Mustard, Ginger, or Warm Water Only on Objective and Subjective Warmth Distribution in Healthy Subjects: A Randomized Controlled Trial.

OBJECTIVE: To analyze the short-term thermogenic effects of footbaths with warm water alone (WA) versus when combined with medicinal powders. DESIGN: Randomized controlled trial with cross-over. INTERVENTIONS AND OUTCOMES: Seventeen healthy volunteers (mean age 22.1 years, SD = 2.4; 11 female) received three footbaths with WA or WA combined with mustard (MU) or ginger (GI) in a randomized order. Self-perceived warmth (Herdecke warmth perception questionnaire) and actual skin temperatures (thermography) were assessed before (t0), immediately after footbaths (t1), and 10 minutes later (t2). The primary outcome was perceived warmth in the feet. Secondary outcomes were warmth perception in the face, hands and overall, as well as actual skin temperature in the feet, face, and hands. RESULTS: Perceived warmth at the feet (primary outcome) increased significantly (all p's < .001) for MU and GI at t1 as well as for GI at t2 when compared to t0 with high effect sizes. At t2, GI differed significantly from WA (p < .001) and MU (p = .048). With regards to the secondary measures of outcome, no significant effects were seen for perceived warmth at the face or hands. Overall warmth was significantly higher at t1 compared to t0 (p = .01). Thermography assessments of skin temperature at the feet at t1 increased after all conditions (p < .001). No effects were seen in the face. At the hands, temperature decreased at t1 (p = .02) and t2 compared to t0 (p < .001). CONCLUSION: The present study provides preliminary evidence that mustard and ginger increase warmth perception at the feet more than warm water alone, with only the effects for GI enduring at the brief follow-up.

Feeling the sound - short-term effect of a vibroacoustic music intervention on well-being and subjectively assessed warmth distribution in cancer patients-A randomized controlled trial.

OBJECTIVES: So far, the effects of vibroacoustic music therapy in cancer patients are unknown. However, used in anthroposophic medicine, it could be an approach to enhance well-being. The goal of this study was to evaluate the immediate effects of a sound-bed music intervention with respect to the subjective well-being as well as body warmth and pain. PATIENTS AND METHODS: We treated 48 cancer patients with 10 min of sound-bed intervention in a cross-over design. Primary outcome was the total sum of the Basler Mood Questionnaire (BMQ), secondary outcomes were subscales of the BMQ and questions addressing body warmth and pain. The EORTC-QLQ C30 was used as baseline assessment for quality of life (QOL). RESULTS: Patients had lower QOL values than the EORTC reference samples (p < .001, d = 0.90). The primary outcome increased after music (p < .001, d = 0.47), no changes were seen in the control condition (p = .73, d = 0.04), the time by condition interaction was significant (p < .05). SECONDARY OUTCOMES: Increase after music for the BMQ subscales inner balance (p < .001, d = 0.73), vitality (p < .001, d = 0.51) and vigilance (p < .001, d = 0.37) as well as for the additional questions satisfaction (p < .001, d = 0.43), current mood (p < .001, d = 0.43), body warmth (p < .05, d = 0.44) and warmth distribution (p < .01, d = 0.49). No significant changes were seen in pain levels and social extroversion. CONCLUSION: Sound-bed intervention improved momentary well-being and caused self-perceived physiological changes associated with relaxation beyond the benefits of simple resting time (control condition). Thus, it might be a promising approach to improve well-being in cancer patients.
