Spirulina may increase people's ability to resist mental and physical fatigue. This study tested that hypothesis in a randomized, double blinded, placebo controlled study in men. After 1 week, a 3 g/day dose of spirulina produced a small, but statistically significant increase in exercise output (Kcals consumed in 30 min exercise on a cross trainer machine). A mathematical based mental fatigue test showed improved performance 4 h after the first time of supplementation as well as 8 weeks later. Similarly, a subjective survey for a sense of physical and mental fatigue showed improvement within 4 h of the first supplementation as well as 8 weeks later. These results show that spirulina intake can affect fatigue in men.

The purpose of the study is to investigate the effectiveness of acupressure on fatigue in patients with end-stage renal-disease (ESRD). The study was a randomized control trial; qualified patients were randomly assigned into acupressure group, sham group or control group. A total of 106 participants were included in the study. The measures included the revised Piper Fatigue Scale (PFS), VAS of Fatigue, the Pittsburgh Sleep Quality Index and the Beck Depression Inventory. Data of fatigue measures were collected at pretreatment and a week following treatment. Sleep quality and depression were collected during post-test only. The statistical methods included the descriptive statistics, one-way ANOVA, ANCOVA, and repeated-measures ANOVA. ANCOVA that adjusted for differences in baseline fatigue scores (PFS), post-test of depression and sleep quality, result was significant, F(2,100)=3.99, p=0.02. Post-hoc tests revealed that patients in the acupressure group were significantly having lower scores of fatigue than patients in the control group. ANCOVA results also significant for VAS of Fatigue among groups, F(2,100)=5.63, p=0.003. Comparisons indicated that there were significant differences between the acupressure group and the control group (p=0.01) and between the sham group and control group (p=0.003). Predialysis fatigue was assessed routinely by using a rating of 0-10. Repeated-measures ANOVA results demonstrate the group main effect was significant in the perceived fatigue (F(2,88)=19.46, p<0.001). Follow-up tests indicated there were significant differences between the acupressure group and the control group (p<0.001) and between the sham group and control group (p<0.001). The study provided an alternative method for health care providers to managing ESRD patients with fatigue.

This study was conducted to investigate the chemical component of the hot water (HW) fraction of mycelia of Cordyceps sinensis and its antifatigue and antistress effect against a stimulus in vivo using rats and mice. The growth of mycelia reached a maximum level of 31.6 g/l after 120 h of incubation. The main chemical composition of the HW fraction of mycelia of C. sinensis was found to be carbohydrate (78.9%) with 5% moisture. The swimming endurance capacity of mice orally administered with the HW fraction (150 and 300 mg/kg/d, respectively) was significantly prolonged from 75 to 90 min with a lessening of fatigue. When the HW fraction (150 mg/kg/d) was given to rats for 8 d including a 48 h stress period, the weight changes of the adrenal gland, spleen, thymus, and thyroid, which is an index of stress, were suppressed. The HW fraction also significantly inhibited the increase in total cholesterol and the decrease in alkaline phosphatase levels as biochemical parameters of immobilization stress in rats.

Background This randomized, blinded, placebo-controlled clinical trial identifies the effect of an aromatherapy blend of essential oils on fatigue, which is one of the most commonly unaddressed symptoms of hypothyroidism, by evaluating the effects of daily aromatherapy inhalation. Methods Participants included women aged 18-55 with a diagnosis of hypothyroidism. Women who had a history of thyroid cancer were excluded, due to the confounding effects of cancer on fatigue as the outcome of interest. Participants were randomized into two groups: the aromatherapy group, treated with inhalation of the essential oil blend, and the control group, treated with an odorless vegetable oil blend. The primary outcome was change from baseline in fatigue scores as measured by the Multidimensional Fatigue Symptom Inventory (MFSI), a validated instrument which measures multiple patterns of fatigue. Results After adjusting for baseline scores, no significant difference was found between the aromatherapy group and the control group at midpoint. Both groups experienced a reduction in symptoms during the first week of the intervention. At the endpoint, participants in the aromatherapy group had improved fatigue scores across all ten subscales, as compared to the control group. Not all improvements achieved statistical significance, indicating that the aromatherapy treatment has a greater effect on the subscales of global, affective, and general fatigue. Conclusions This is the first study to evaluate the effects of aromatherapy on fatigue among women with hypothyroidism. These findings provide evidence that regular inhalation of an aromatherapy blend may reduce fatigue among women with hypothyroidism, particularly in the areas of global, affective, and general fatigue.

BACKGROUND AND PURPOSE:Fatigue is a common complication of hemodialysis. This study aimed to compare the effects of aromatherapy with essential oils of lavender and orange on the fatigue of hemodialysis patients.

MATERIALS AND METHODS:Ninety subjects were randomly allocated into three groups of aromatherapy with lavender essential oil, aromatherapy with orange essential oil and control. Data collection tool was the Fatigue Severity Scale. In each experimental group, subjects inhaled five drops of lavender essential oil and orange essential oil.

RESULTS:The difference in the mean of fatigue before and after the intervention in each of the experimental groups was statistically significant, but this difference was not significant in the control group. Between the two groups of aromatherapy, no significant difference was observed in terms of the mean fatigue after the intervention.

CONCLUSION:Aromatherapy with lavender essential oil and orange essential oil might reduce fatigue in hemodialysis patients.

This study aimed to investigate whether balneotherapy (BT) applied in combination with physical therapy (PT) has a more positive effect in patients aged 65 years and older with knee osteoarthritis (KOA) compared to PT alone. A total of 305 individuals were randomized into two groups. Group I was applied PT alone; group II was applied PT + BT. Assessments were made using the Pain (VAS), EQ-5D-3L Scale, Western Ontario And McMaster Universities Osteoarthritis Index (WOMAC), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) Scale, Epworth Sleepiness scale (EPWORTH) and the Outcome Measures in Rheumatology-The Osteoarthritis Research Society International set of responder criteria for osteoarthritis (OMERACT-OARSI) at the beginning (T0) and at the end (T1) of treatment. Statistically significant interactions found between treatment (PT alone or PT + BT) and time (before treatment and after treatment) in terms of Pain-VAS, Pain-WOMAC, Stiffness-WOMAC, Physical Function-WOMAC, Total-WOMAC, EQ-5D, EQ-VAS, FACIT-F, and EPWORTH scores (p < 0.0001 for all). According to OMERACT-OARSI criteria, the responder rate was 89.04% in PT alone group and 98.74% in PT + BT group. Balneotherapy plus physical therapy was more effective than physical therapy alone in KOA patients aged over 65 years. Reducing pain, especially, positively contributes to functionality, quality of life, fatigue and sleepiness of KOA patients.

BACKGROUND:Fatigue is a debilitating symptom in haemodialysis patients. Qigong presents a potentially safe modality of treatment for chronic fatigue patients but has not yet been evaluated in haemodialysis patients.

OBJECTIVE:The aim of this study is to investigate whether qigong exercise affects fatigue in haemodialysis patients.

DESIGN:A 6-month non-randomized control trial with six measurement periods was conducted. The qigong group was taught to practice qigong three times per week for six months. The control group received usual routine care. Main outcome measure Fatigue, as measured by the"Haemodialysis Patients Fatigue Scale".

RESULTS:A total of 172 patients participated in this study, with 71 patients in the qigong group and 101 patients in the control group. The results indicated that all patients experienced mild to moderate fatigue. There was no difference between the qigong and control groups in fatigue at baseline. However, fatigue was lower in the qigong group than in the control group at 8 weeks (43.5 vs. 53.9), 12 weeks (44.7 vs. 53.6), 16 weeks (43.2 vs. 50.8), 20 weeks (42 vs. 50.2), and 24 weeks (41.4 vs. 48.4). The results, based on the generalized estimating equation method, showed that fatigue was significantly lower in the qigong group than in the control group (odds ratio=0.004, p=0.005).

CONCLUSION:Fatigue in the qigong group showed a continuous decrease, which was maintained until the end of data collection at 24 weeks. Thus, qigong presents a potentially effective and safe method to reduce fatigue in haemodialysis patients.

PURPOSE:The purpose of this study was to examine the effects of laughter therapy on postpartum fatigue and stress responses of postpartum women.

METHODS:The research design was a nonequivalent control group non-synchronized design. The participants were 67 postpartum women who agreed to participate in this study, selected by convenience sampling: (experiment group-33 and control group-34). The data were collected from August 5 to September 30, 2010. The experimental group received laughter therapy from a laughter therapy expert for 60 min, twice a week for 2 weeks, a total of 4 sessions. To evaluate the effects of laughter therapy, postpartum fatigue by self-report questionnaire and cortisol concentration in breast milk were measured. The data were analyzed using the SPSS WIN 13.0 Program.

RESULTS:The first hypothesis that"the degree of postpartum fatigue in the experimental group participating in laughter therapy would be lower than that of the control group"was accepted. These findings indicate that laughter therapy has a positive effect on decreasing postpartum fatigue.

CONCLUSION:The finding provides evidence for use of complementary and alternative nursing in Sanhujori facilities and obstetric units to reduce postpartum women's fatigue.

Isolated cases and small series have described the development of complex regional pain syndrome, postural orthostatic tachycardia, and fibromyalgia after human papillomavirus (HPV) vaccination. These illnesses are difficult to diagnose and have overlapping clinical features. Small fiber neuropathy and dysautonomia may play a major role in the pathogenesis of these entities. We used the following validated questionnaires to appraise the chronic illness that might appear after HPV vaccination: The 2010 American College of Rheumatology Fibromyalgia Diagnostic Criteria, COMPASS 31 dysautonomia questionnaire, and S-LANSS neuropathic pain form. These questionnaires and a"present illness"survey were e-mailed to persons who had the onset of a chronic ailment soon after HPV vaccination. Forty-five filled questionnaires from individuals living in 13 different countries were collected in a month's period. Mean (±SD) age at vaccination time was 14 ± 5 years. Twenty-nine percent of the cases had immediate (within 24 h) post-vaccination illness onset. The most common presenting complaints were musculoskeletal pain (66%), fatigue (57%), headache (57%), dizziness/vertigo (43%), and paresthesias/allodynia(36%). Fifty-three percent of affected individuals fulfill the fibromyalgia criteria. COMPASS-31 score was 43 ± 21, implying advanced autonomic dysfunction. Eighty-three percent of the patients who had ongoing pain displayed S-LANSS values>12, suggesting a neuropathic component in their pain experience. After a mean period of 4.2 ± 2.5 years post-vaccination, 93% of patients continue to have incapacitating symptoms and remain unable to attend school or work. In conclusion, a disabling syndrome of chronic neuropathic pain, fatigue, and autonomic dysfunction may appear after HPV vaccination.

OBJECTIVE:In 2002 we suggested a new hypothesis of migraine. This hypothesis implies that migraine is a consequence of a loss of neurohormonal and metabolic integrity. The goal of this clinical analysis is to present the evaluation of the effect of a multimodal treatment program in migraine management.

MATERIAL AND METHODS:We evaluated 30 patients ages 16-66 with migraine who were treated with a multimodal treatment program. All patients received a complex program which included: hormonorestorative therapy (HT) with bio-identical hormones; correction of balance between sympathetic and parasympathetic systems and simultaneously calcium/magnesium balance;"resetting"the pineal gland; improvement of intestinal absorption through restoration of normal intestinal flora, and a cleanse from parasitic infestation (if necessary). Serum levels of total cholesterol (TC), pregnenolone, dehydroepiandrosterone sulfate (DHEAS), progesterone, total estrogen, and total testosterone were determined,

RESULTS:All patients responded to this regimen. We do not have patients who still have migraine after they started to use this program. Laboratory finding prior to HT showed the significant deficiency in production of all basic steroid hormones (progesterone and pregnenolone production declined the most). Concurrent symptoms such as fibromyalgia, insomnia, depression, gastrointestinal disorders, and fatigue had disappeared. Total cholesterol completely normalized in 22 (91.7%) patients. No adverse effects or complications related to this program were registered.

CONCLUSIONS:Our findings support the hypothesis that migraine is a consequence of a loss of neurohormonal and metabolic integrity, and that migraine can be managed by a multimodal approach.

The syndrome of heart failure (HF) promotes central and peripheral dysfunctions that result in functional capacity decrease, leading to fatigue, dyspnea, and exercise intolerance. The use of light-emitting diode therapy (LEDT) has shown good results reducing fatigue and exercise intolerance, when applied on skeletal muscles before or after exercises. Thereby, the aim of this study was to compare the effects of LEDT on functional capacity, aerobic power, and hemodynamic function in HF rats. Male Wistar rats (230-260 g) were randomly allocated into three experimental groups: Sham (n = 6), Control-HF (n = 4), and LEDT-HF (n = 6). The animals were subjected to an exercise performance test (ET) with gas analysis coupled in a metabolic chamber for rats performed two times (6 and 14 weeks after myocardial infarction). On the day after the baseline aerobic capacity test, the animals were submitted during 8 weeks to the phototherapy protocol, five times/week, 60 s of irradiation, 6 J delivered per muscle group. Statistical analysis was performed by one- and two-way ANOVAs with repeated measuresand Student-Newman-Keuls post hoc tests (p ≤ 0.05). Comparing the percentage difference (Δ) between baseline and the final ET, there was no significant difference for the VO2max variable considering all groups. However, Sham and LEDT-HF groups showed higher relative values than the Control-HFgroup, respectively, for distance covered (27.7 and 32.5 %), time of exercise test (17.7 and 20.5 %), and speed (13.6 and 12.2 %). In conclusion, LEDT was able to increase the functional capacity evaluated by distance covered, time, and speed of exercise in rats with HF.

BACKGROUND:Patients suffering from Multiple Sclerosis (MS) experience a wide array of symptoms, including balance problems, mobility impairment, fatigue and depression. Physical exercise has recently been acknowledged as a treatment option complementary to medication. However, information regarding putative effects of structured exercise programs on neurological symptoms is sparse. Tai Chi, a Chinese martial art incorporating physical exercise and mindfulness training, has been shown to yield health benefits in various neurological groups. It seems particularly suitable for patients with motoric deficits as it challenges coordination and balance. The purpose of the current study was to explore the therapeutic value of structured Tai Chi training for coordination, balance, fatigue and depression in mildly disabled MS patients.

METHODS:A sample of 32 MS patients (Expanded Disability Status Scale, EDSS < 5) was examined. A structured Tai Chi course was devised and a Tai Chi group participated in two weekly sessions of 90 minutes duration for six months, while a comparison group received treatment as usual (TAU). Both groups were examined prior to and following the six-months interval with regards to balance and coordination performance as well as measures of fatigue, depression and life satisfaction.

RESULTS:Following the intervention, the Tai Chi group showed significant, consistent improvements in balance, coordination, and depression, relative to the TAU group (range of effect-sizes: partialη2 = 0.16 - 0.20). Additionally, life satisfaction improved (partial η2 = 0.31). Fatigue deteriorated in the comparison group, whereas it remained relatively stable in the Tai Chi group (partial η2 = 0.24).

CONCLUSIONS:The consistent pattern of results confirms that Tai Chi holds therapeutic potential for MS patients. Further research is needed to determine underlying working mechanisms, and to verify the results in a larger sample and different MS subgroups.

BACKGROUND:Infections with human papilloma virus (HPV) can result in cervical, oropharyngeal, anal, and penile cancer and vaccination programs have been launched in many countries as a preventive measure. We report the characteristics of a number of patients with a syndrome of orthostatic intolerance, headache, fatigue, cognitive dysfunction, and neuropathic pain starting in close relation to HPV vaccination.

METHODS:Patients were referred for orthostatic intolerance following HPV vaccination. Symptoms of autonomic dysfunction were quantified by standardised questionnaire. The diagnosis of postural orthostatic tachycardia syndrome (POTS) rested on finding a sustained heart rate increment of>30 min(-1) (>40 min(-1) in adolescents) or to levels>120 min(-1) during orthostatic challenge.

RESULTS:35 women aged 23.3± 7.1 years participated. Twenty-five had a high level of physical activity before vaccination and irregular periods were reported by all patients not on treatment with oral contraception. Serum bilirubin was below the lower detection limit in 17 patients. Twenty-one of the referred patients fulfilled the criteria for a diagnosis of POTS (60%, 95%CI 43-77%). All patients had orthostatic intolerance, 94% nausea, 82% chronic headache, 82% fatigue, 77% cognitive dysfunction, 72% segmental dystonia, 68% neuropathic pain.

CONCLUSIONS:In a population referred for symptoms of orthostatic intolerance and other symptoms consistent with autonomic dysfunction that began in close temporal association with a quadrivalent HPV vaccination, we identified a 60% prevalence of POTS. Further work is urgently needed to elucidate the potential for a causal link between the vaccine and circulatory abnormalities and to establish targeted treatment options for the affected patients.

Fatigue is an extremely common side effect experienced during cancer treatment and recovery. Limited research has investigated strategies stemming from complementary and alternative medicine to reduce cancer-related fatigue. This research examined the effects of Reiki, a type of energy touch therapy, on fatigue, pain, anxiety, and overall quality of life. This study was a counterbalanced crossover trial of 2 conditions: (1) in the Reiki condition, participants received Reiki for 5 consecutive daily sessions, followed by a 1-week washout monitoring period of no treatments, then 2 additional Reiki sessions, and finally 2 weeks of no treatments, and (2) in the rest condition, participants rested for approximately 1 hour each day for 5 consecutive days, followed by a 1-week washout monitoring period of no scheduled resting and an additional week of no treatments. In both conditions, participants completed questionnaires investigating cancer-related fatigue (Functional Assessment of Cancer Therapy Fatigue subscale [FACT-F]) and overall quality of life (Functional Assessment of Cancer Therapy, General Version [FACT-G]) before and after all Reiki or resting sessions. They also completed a visual analog scale (Edmonton Symptom Assessment System [ESAS]) assessing daily tiredness, pain, and anxiety before and after each session of Reiki or rest. Sixteen patients (13 women) participated in the trial: 8 were randomized to each order of conditions (Reiki then rest; rest then Reiki). They were screened for fatigue on the ESAS tiredness item, and those scoring greater than 3 on the 0 to 10 scale were eligible for the study. They were diagnosed with a variety of cancers, most commonly colorectal (62.5%) cancer, and had a median age of 59 years. Fatigue on the FACT-F decreased within the Reiki condition (P=.05) over the course of all 7 treatments. In addition, participants in the Reiki condition experienced significant improvements in quality of life (FACT-G) compared to those in the resting condition (P<.05). On daily assessments (ESAS) in the Reiki condition, presession 1 versus postsession 5 scores indicated significant decreases in tiredness (P<.001), pain (P<.005), and anxiety (P<.01), which were not seen in the resting condition. Future research should further investigate the impact of Reiki using more highly controlled designs that include a sham Reiki condition and larger sample sizes.
