The effect of different high-intensity interval training protocols on cardiometabolic and inflammatory markers in sedentary young women: A randomized controlled trial.

Few studies have reported the cardiovascular health effects of different high-intensity interval training (HIIT) protocols among sedentary young women. We investigated the impact of a traditional HIIT programme and a high-intensity circuit training (HICT) programme on lipid profiles and inflammatory cytokine levels in sedentary young women. Forty-two women were randomly assigned to HICT (body weight-based training), HIIT (cycling-based training), or control groups (n = 14 each). HICT and HIIT participants completed an 8-week training programme of three sessions per week. Total cholesterol (TC), triglyceride, high- and low-density lipoprotein, leptin, resistin, tumour necrosis factor-alpha (TNF-α), interleukin-8, and interferon-gamma levels were measured before and after the intervention. Post-intervention, TC and leptin were decreased in the HICT group. The HICT group also demonstrated increased lean mass, upper and lower limb strength, and balance, while the HIIT group displayed improved lower limb strength. Additionally, the control group showed significant increases in triglyceride levels, weight, body mass index, and fat mass. In conclusion, although both HICT and HIIT interventions showed improvements in cardiovascular health and physical fitness, participants in the HICT group experienced more health benefits.

Differences Between Students With Comorbid Intellectual Disability and Autism Spectrum Disorder and Those With Intellectual Disability Alone in the Recognition of and Reaction to Emotions.

This study investigates whether students with intellectual disability (ID) alone differ from students with combined individual disability and autism spectrum disorder (ASD) in their recognition of emotions. The ability to recognise emotions does not mean that students automatically know how to react to these emotions. Differences in performance on recognition and reaction tasks are examined. Participants were 20 primary 6 students who had ID with ASD and 20 primary 6 students who had ID without ASD from four special schools. The testing and training materials were adapted from a local teaching package. The results showed that both groups exhibited similar performance patterns in recognition tasks. Students with comorbid ASD exhibited inferior performance in tasks requiring reactions to complex emotions.

Effects of Transcranial Direct Current Stimulation Combined With Neuromuscular Electrical Stimulation on Upper Extremity Motor Function in Patients With Stroke.

OBJECTIVE: The aim of the study was to investigate the treatment effects of transcranial direct current stimulation combined with neuromuscular electrical stimulation on the motor function of upper extremity in persons with stroke. DESIGN: This study was a pilot double-blind randomized controlled trial. Twenty-six patients due to stroke onset of more than 6 mos were randomly allocated to three groups: transcranial direct current stimulation combined with neuromuscular electrical stimulation group, transcranial direct current stimulation group, or control group. In addition to conventional rehabilitation, all subjects received one of the three protocols in a total of 15 sessions for 3 wks. RESULTS: A significant difference among the three groups was found for the change scores of the Fugl-Meyer Assessment upper extremity subscale from pretreatment to 1-mo follow-up (P = 0.02), in favor of the transcranial direct current stimulation combined with neuromuscular electrical stimulation group. Moreover, the transcranial direct current stimulation combined with neuromuscular electrical stimulation group showed significant within-group improvement on the Fugl-Meyer Assessment upper extremity (from preintervention to postintervention, P = 0.01) and the Action Research Arm Test (from preintervention to postintervention and to 1-mo postintervention, P = 0.03 and P = 0.04, respectively). CONCLUSIONS: This preliminary study reveals that combining transcranial direct current stimulation and neuromuscular electrical stimulation with regular rehabilitation programs may enhance better upper extremity functional improvement than regular rehabilitation programs alone in patients with chronic stroke.

Development and pilot evaluation of the Cognition domain of the Hong Kong Comprehensive Assessment Scales for Toddlers.

Purpose: To describe the development of the Cognition domain of the Hong Kong Comprehensive Assessment Scales for Toddlers (HKCAS-T).Methods: Participants included 345 toddlers aged 18-41 months, with 258 recruited from Maternal and Child Health Centers (MCHCs) and 87 with cognitive delay recruited from Child Assessment Centers (CACs). They were individually administered the 83-item pilot version by medical practitioners or educational psychologists between 2017 and 2019 in MCHCs and CACs in Hong Kong.Results: Rasch analysis results supported the unidimensionality of the pilot version, after removing six items. Analysis of covariance results indicated that both the 83-item version and the 77-item version could differentiate between children of different age groups, and children with typical development from children with cognitive delay. Internal consistency and interrater reliability were 0.90 or above.Conclusions: The Cognition domain of the HKCAS-T is a promising developmental assessment tool for the assessment of toddlers.

Preservice teachers' neuroscience literacy and perceptions of neuroscience in education: Implications for teacher education.

BACKGROUND: Owing to the prevalence of neuromyths in education, there has been a call for more teacher training in neuroscience. However, neuroscience is rarely featured in teacher education. This study investigated the neuroscience literacy and perceptions of neuroscience in education among preservice teachers in order to inform future development of initial teacher education. METHOD: Neuroscience literacy of 968 preservice teachers and their perceptions towards applying neuroscience in education were examined using survey items adapted from studies addressing similar constructs. Rasch item response theory and classical test theory techniques were employed for data analysis. RESULTS: Most of the preservice teachers had limited brain knowledge and subscribed to many common neuromyths but were positive towards applying neuroscience in education. General brain knowledge was the only predictor for ability to identify neuromyths (ß = .564). CONCLUSION: Neuroscience knowledge can help safeguard preservice teachers against neuromyths. Neuroscience training deserves a place in teacher education.

Immediate effects of noxious and innocuous thermal stimulation on brain activation in patients with stroke.

Case-control studies have shown that noxious thermal stimulation (TS) can improve arm function in patients with stroke. However, the neural mechanisms underlying this improvement are largely unknown. We explored functional neural activation due to noxious and innocuous TS intervention applied to the paretic arm of patients with stroke. Sixteen participants with unilateral cortical infarctions were allocated to one of two groups: noxious TS (8 patients; temperature combination: hot pain 46°C to 47°C, cold pain 7°C-8°C) or innocuous TS (n = 8; temperature combination: hot 40°C-41°C, cold 20°C-21°C). All subjects underwent fMRI scanning before and after 30 min TS intervention and performed a finger tapping task with the affected hand. Immediate brain activation effects were assessed according to thermal type (noxious vs. innocuous TS) and time (pre-TS vs post-TS). Regions activated by noxious TS relative to innocuous TS (P < .05, adjusted for multiple comparisons) were related to motor performance and sensory function in the bilateral primary somatosensory cortices, anterior cingulate cortex, insula, thalamus, hippocampus and unilateral primary motor cortex, secondary somatosensory cortex at the contralateral side of lesion, and unilateral supplementary motor area at the ipsilateral side of lesion. Greater activation responses were observed in the side contralateral to the lesion, suggesting a significant intervention effect. Our preliminary findings suggest that noxious TS may induce neuroplastic changes unconstrained to the local area.Trial registration: NCT01418404.

Effects of the hybrid of neuromuscular electrical stimulation and noxious thermal stimulation on upper extremity motor recovery in patients with stroke: a randomized controlled trial.

BACKGROUND: Neuromuscular electrical stimulation (NMES) and noxious thermal stimulation (NTS) have been developed and incorporated in stroke rehabilitation. OBJECTIVE: This study aimed to compare the effects of NMES, NTS, and the hybrid of NMES and NTS ("Hybrid") on motor recovery of upper extremity (UE) for patients with stroke. METHODS: We conducted a prospective, single-blind randomized controlled trial with concealed allocation. Forty-three patients with chronic stroke (onset >6 months) were randomly assigned to three groups (NMES, NTS, and "Hybrid"). In addition to conventional rehabilitation, participants received 30 min of NMES or 30 min of NTS or 15 min of NTS followed by 15 min of NMES. The treatment period was 8 weeks, 3 days/week, 30 min/time. The UE subscale of Fugl-Meyer assessment (UE-FMA, the primary outcome), Motricity index, modified Ashworth scale, and Barthel index were administered by a blinded assessor at baseline, posttreatment, and one-month follow-up. RESULTS: Most of the participants had mild-to-moderate disability in activity of daily living. No significant differences in the outcome measures at posttreatment and one-month follow-up were found among the NMES group (n = 13), NTS group (n = 13), and the hybrid of NMES and NTS group (n = 17). However, significant score changes in UE-FMA (p < 0.025) from baseline to posttreatment and one-month follow-up were found for the "Hybrid" group. CONCLUSIONS: This study reveals that the hybrid of NMES and NTS therapy appears to be beneficial to UE recovery after stroke but is not superior to NMES or NTS alone.

The effect of rigid taping with tension on mechanical displacement of the skin and change in pain perception.

OBJECTIVES: To investigate the effect of rigid taping that induces mechanical displacement of the skin on pain perception. DESIGN: Single group experiment design with repeated measures. METHODS: Twenty-three active healthy volunteers (12 men and 11 women) participated in the study. All participants received three different taping procedures: no tape, taping with tension, and taping without tension. The order of three taping conditions was randomised. Skin displacement was measured during taping with tension. A pressure algometer was used to measure the level of pain perception once before taping, and again after each taping condition, in one testing session. The participants were blind to the values of their pressure pain threshold (PPT) during the experimental period. RESULTS: The mean±SD skin displacement in the condition of taping with tension was 2.58±0.49cm. There were significant differences in PPT between taping with tension and taping without tension (mean difference (mean diff)±standard error (SE) 36.43±4.22kPa, p=0.000) and no tape (mean diff±SE 44.31±3.13kPa, p=0.000). No significant difference in PPT between no tape and taping without tension was found (mean diff±SE 7.88±2.83kPa, p=0.067). CONCLUSIONS: Taping with tension increases the threshold of pressure pain perception. Therefore, stretch and compression caused by rigid taping with tension could disturb the nociceptive signal transmission and alter pain perception.

A Tailor-Made Exercise Program for Improving Balance and Mobility in Older Adults With Type 2 Diabetes.

Effectiveness of an exercise program designed for improving postural control and mobility in older adults with type 2 diabetes was investigated. Ninety-three adults 65 or older diagnosed with type 2 diabetes and able to walk unaided were recruited. The intervention group received exercise training focused on ankle strengthening and mobility twice per week for 10 weeks. The control group did not participate in any exercise program. After 10 weeks, the intervention group showed significantly greater improvement in the mean Sensory Organization Test composite score (4.4 vs. 0.3; p = 0.01) as well as visual ratio (0.1 vs. 0.002; p = 0.01) and vestibular ratio (0.1 vs. 0.003; p < 0.001) than the control group after adjusting for covariates. A greater trend of improvement in the Timed Up and Go and Single-Leg Stance Test was also found in the intervention group. Exercise training focusing on the ankle is effective in enhancing the postural stability of older adults with type 2 diabetes and can potentially be effective in improving single-leg standing balance and mobility. [Journal of Gerontological Nursing, 44(2), 41-48.].

The association between physical characteristics of the ankle joint and the mobility performance in elderly people with type 2 diabetes mellitus.

Previous studies showed that older adults with diabetes have a worse mobility performance as compared with those without diabetes. Studies also demonstrated that older adults with diabetes have weakened ankle muscle strength, reduced joint range in ankle dorsiflexion and worsened ankle joint proprioception as compared with control population. The purpose of the present study was to examine the relationship between the physical characteristics of the ankle joint and the mobility performance in older adults with type 2 diabetes. Older adults with type 2 diabetes (n=85) were recruited, and Timed Up and Go test (TUG) for mobility assessment was performed. Active ankle joint repositioning test was used for assessing the ankle joint proprioception sense; peak torque of ankle dorsiflexors and plantar flexors were tested by using a Cybex Norm dynamometer, and weight-bearing lunge test (WBLT) was used for assessing the stiffness of ankle dorsiflexion. Our results showed that age, body mass index (BMI), normalized peak torque of plantar flexors and dorsiflexors, active ankle joint repositioning test errors and the WBLT distance were significantly correlated with the TUG (all p<0.001). These ankle characteristics, together with the demographic data of the subjects, contributed 59.9% of the variance in the TUG by multiple regression analysis. Body mass, ankle plantar flexors strength and ankle joint proprioception are important factors contributing to the physical mobility of the older adults with type 2 diabetes.

Effect of biofeedback cycling training on functional recovery and walking ability of lower extremity in patients with stroke.

This study aimed to investigate the effectiveness of biofeedback cycling training on lower limb functional recovery, walking endurance, and walking speed for patients with chronic stroke. Thirty-one patients with stroke (stroke onset >3 months) were randomly assigned into two groups using a crossover design. One group (N = 16; mean: 53.6 ± 10.3 years) underwent conventional rehabilitation and cycling training (30 minutes/time, 5 times per week for 4 weeks), followed by only conventional rehabilitation for another 4 weeks. The other group (N = 15; mean: 54.5 ± 8.0 years) underwent the same training in reverse order. The bike used in this biofeedback cycling training was the MOTOmed viva2 Movement Trainer. Outcome measures included the lower extremity subscale of Fugl-Meyer assessment (LE-FMA), the 6-minute walk test (6MWT), the 10-meter walk test (10MWT), and the modified Ashworth scale (MAS). All participants were assessed at the beginning of the study, at the end of the 4(th) week, and at the end of the 8(th) week. Thirty participants completed the study, including the cycling training interventions and all assessments. The results showed that improvements in the period with cycling training were significantly better than the noncycling period in the LE-FMA (p < 0.05), 6MWT (p < 0.001), 10MWT (p < 0.001), and MAS (p < 0.001) scores. No significant carryover effects were observed. The improvements on outcome measures were significantly different between the cycling period and the noncycling period after adjusting for potential confounding factors in the multivariate analysis of variance (p < 0.001). The study result indicates that the additional 4-week biofeedback cycling training could lead to improved LE functional recovery, walking endurance, and speed for patients with chronic stroke.

Validation of the Gumpel Readiness Inventory for preschool children in Hong Kong.

The aim of this study was to validate the Chinese version of the Gumpel Readiness Inventory (RI). Participants included 653 preschool children aged three to five years old, their teachers and parents, and 49 children with developmental disabilities. Teachers and parents completed the RI and parents completed the Strength and Difficulty Questionnaire (SDQ) as well. Each child was individually assessed on the cognitive domain of Preschool Developmental Assessment Scale (PDAS). The results showed that the parent's and teacher's versions of RI correlated with SDQ and PDAS. The RI scores of the children with developmental disabilities were significantly lower than that of the children with typical development. Older children attained higher RI scores than younger children. The internal consistency and the test-retest reliability (both parent's and teacher's versions) were above .70. To conclude, the Chinese version of the RI is a reliable, valid and quick instrument for measuring the school readiness of Hong Kong preschool children.

Item hierarchy of the Chinese version of cerebral palsy quality of life for children.

BACKGROUND: The Chinese Cerebral Palsy Quality of Life for Children (C CP QOL-Child) is the first instrument developed to measure quality of life of (QOL) children with cerebral palsy in Chinese speaking populations. OBJECTIVE: The aim of the study was to examine the psychometric properties of C CP QOL-Child using Item Response Theory Models. We were particularly interested to know how intervention strategies could be designed for individuals based on the item scores. METHODS: 145 primary caregivers (mostly mothers; mean age: 39.2) of children with cerebral palsy aged 4-12 were invited to complete the 65-item C CP QOL-Child questionnaire. Data were analyzed using Rasch analysis. RESULTS: Item difficulty estimates were aligned with person ability values, indicating that the items in the scale generally demonstrated an appropriate depth and width for measuring QOL of persons in the target population. The results also showed that after dropping the 8 items in the dimension pain and impact of disability in the 65-item scale, the revised 57-item scale exhibits unidimensionality (separation index = 4.43, r = 0.95); hence the total score computed from the 57 items adequately reflects the level of QOL of the child as perceived by the caregiver. We further found that the Rasch item difficulty estimates demonstrated an overall item hierarchy; hence therapists can expect a pattern of performance by a child with CP that is based on the established order of item difficulty. CONCLUSIONS: The hierarchical structure identified in the study may be useful for designing tailor-made interventions with an aim of improving QOL.

Test-retest reproducibility of two short-form balance measures used in individuals with stroke.

The aim of this study is to determine the test-retest reproducibility of the seven-item Short-Form Berg Balance Scale (SFBBS) and the five-item Short-Form Postural Assessment Scale for Stroke Patients (SFPASS) in individuals with chronic stroke. Fifty-two chronic stroke patients from two rehabilitation departments were included in the study. Both balance measures were administered twice 7 days apart. Test-retest reliability was analysed using the weighted κ (κ(w)) statistic for each item and intraclass correlation coefficients (ICC(2,1)) for the total scores of both measures. Agreement was expressed as the SEM, minimal detectable change and limits of agreement by Bland and Altman analysis. Test-retest agreements were good to very good for SFBBS and SFPASS, with weighted κ values ranging from 0.75 to 0.89 and 0.66 to 0.84, respectively. The ICCs for the total SFBBS and SFPASS scores were excellent (ICC(2,1): SFBBS=0.99; SFPASS=0.93). The SEMs for both measures were less than 10% of the score range; the minimal detectable changes of the SFBBS and SFPASS were 2.83 and 2.16, respectively, indicating that both measures had a small and acceptable measurement error. Both measures showed good reproducibility. These results indicate that the SFBBS and SFPASS are useful for clinicians and researchers for the evaluation of balance performance and to determine whether the change score of an individual with stroke is real.

Effects of Functional Fascial Taping on pain and function in patients with non-specific low back pain: a pilot randomized controlled trial.

OBJECTIVES: To compare the short-term and medium-term effect of Functional Fascial Taping to placebo taping on pain and function in people with non-specific low back pain. DESIGN: A pilot randomized controlled trial with a 2-week intervention, and 2-, 6- and 12-week follow-up. SETTING: Individuals with non-specific low back pain recruited from local communities. PARTICIPANTS: Forty-three participants with non-specific low back pain for more than 6 weeks were randomized into either Functional Fascial Taping group (n = 21) or placebo group (n = 22). INTERVENTIONS: The intervention group was treated with Functional Fascial Taping while the control group was treated with placebo taping. Both groups received four treatments over 2 weeks. MAIN OUTCOME MEASURES: Worst and average pain and function were assessed at baseline, after the 2-week intervention, and at 6 and 12 weeks follow-up. RESULTS: The Functional Fascial Taping group demonstrated significantly greater reduction in worst pain compared to placebo group after the 2-week intervention (P = 0.02, effect size = 0.74; 95% confidence interval 0.11-1.34). A higher proportion of participants in Functional Fascial Taping group attained the minimal clinically important difference in worst pain (P = 0.007) and function (P = 0.007) than those in placebo group after the 2-week intervention. There were no significant differences in either group's disability rating or clinically important difference in average pain at any time. CONCLUSIONS: Functional Fascial Taping reduced worst pain in patients with non-acute non-specific low back pain during the treatment phase. No medium-term differences in pain or function were observed.

Motor factors associated with health-related quality-of-life in ambulatory children with cerebral palsy.

OBJECTIVE: This study aimed to examine the relationship between fine and gross motor skills and cerebral palsy-specific quality-of-life in ambulatory children with cerebral palsy. DESIGN: Thirty-nine children with cerebral palsy (29 boys, 10 girls; mean age ± SD, 8.8 ± 2.3 yrs) classified under Gross Motor Function Classification System Level I or II were enrolled. Health-related quality-of-life was evaluated using the Cerebral Palsy Quality of Life Questionnaire for Children (parent-proxy version). Motor functions were measured using the Bruininks-Oseretsky Test of Motor Proficiency. RESULTS: Regression analysis for QOL revealed fine motor skills, including upper-limb speed and dexterity, which are positively correlated to functioning (r = 0.205, P < 0.01), and visual-motor control that is positively correlated to other domains, including social well-being and acceptance, participation and physical health, emotional well-being and self-esteem, and family health (r = 0.150-0.188, P < 0.05). CONCLUSIONS: Fine motor functions, including upper-limb speed and dexterity and visual-motor control, were the most important motor factors associated with health-related quality-of-life in ambulatory children with cerebral palsy.

Motor ability and adaptive function in children with attention deficit hyperactivity disorder.

Attention deficit hyperactivity disorder (ADHD) is a common neuropsychiatric disorder. Previous studies have reported that children with ADHD exhibit deficits of adaptive function and insufficient motor ability. The objective of this study was to investigate the association between adaptive function and motor ability in children with ADHD compared with a group of normal children. The study group included 25 children with ADHD (19 boys and 6 girls), aged from 4.6 years to 8.6 years (mean±standard deviation, 6.5±1.2). A group of 24 children without ADHD (normal children) were selected to match the children with ADHD on age and gender. The Movement Assessment Battery for Children, which includes three subtests, was used to assess the motor ability of the children of both groups. The Chinese version of Adaptive Behavior Scales, which consists of 12 life domains, was used to assess adaptive function of the children with ADHD. Compared with the normal children, children with ADHD exhibited poorer motor ability on all the three subtests of motor assessment. In the ADHD group, nine (36%) children had significant motor impairments and seven (28%) were borderline cases. A total of 10 (40%) children with ADHD had definite adaptive problems in one or more adaptive domains. With statistically controlling of IQ for the ADHD group, those children with impaired motor ability had significantly poorer behaviors in the adaptive domain of home living (p=0.035). Moreover, children with ADHD who had severely impaired manual dexterity performed worse than the control group in the adaptive domains of home living (r=-0.47, p=0.018), socialization (r=-0.49, p=0.013), and self-direction (r=-0.41, p=0.040). In addition, children with poorer ball skills had worse home living behavior (r=-0.56, p=0.003). Children who had more impaired balance exhibited poorer performance in social behavior (r=-0.41, p=0.040). This study found significant correlation between motor ability and adaptive function in children with ADHD, especially in their adaptive domains of home living, socialization, and self-direction. In clinical settings, identification of motor difficulties may have important implications for the understanding of relative factors in effective management of the adaptive dysfunction in children with ADHD.

Examining changes in self-perceived quality of life in children and adolescents with physical disability using a longitudinal design.

PURPOSE: The study aimed to investigate the changes in self-perceived quality of life (QOL) of children and adolescents with physical disability (PD). METHOD: Two hundred students aged 10-18 with PD were recruited from primary and high schools in Taiwan to participate in this longitudinal study. The Student Version of the Comprehensive Quality of Life Scale (COMQOL-S) was used to measure self-perceived QOL, which was recorded at baseline, and 6, 12 and 18 months post-baseline. Statistically, linear mixed models were used to compare the QOL scores among the four time points. RESULTS: At the second, third and fourth visit, 192, 151 and 128 participants completed COMQOL-S, respectively. Significant changes over time were found in overall objective and subjective OQL scores (slope = 0.8, p = 0.002 and slope = -1.3, p < 0.001, respectively). Specifically, significant reductions of the subjective QOL scores over the period of the four visits were observed in five domains, namely, Productivity (slope  =  -1.7, p = 0.005), Intimacy (slope  =  -1.6, p = 0.004), Safety (slope = -1.6, p = 0.008), Place in community (slope  =  -1.4, p = 0.019) and Emotional wellbeing (slope  =  -2.5, p < 0.001). Age was negatively correlated with the change of overall subjective score. Positive correlation was found between the change in mean objective scores and mean subjective scores in the Intimacy and Productivity domains. CONCLUSIONS: Even though the conditions of material wellbeing and health can be kept steady, the overall QOL of children and adolescents with PD could still decline over time. This might be attributable to the fact that social life becomes more sophisticated when children become older.

Grip force control is dependent on task constraints in children with and without developmental coordination disorder.

Excessive grip force (GF) is often found in children with developmental coordination disorder (DCD). However, their GF control may vary when task constraints are imposed upon their motor performance. This study aimed to investigate how their GF control changes in response to task demands, and to examine their tactile sensitivity. Twenty-one children with DCD and 17 controls participated in the study. The instrument used to measure GF was a cylindrical cup equipped with a load cell. The children were asked to hold and transport three cups with varying physical properties as quickly as possible. For tactile function, static and moving two-point discrimination senses were recorded. Data were analyzed using repeated-measures analysis of covariance. Children with DCD displayed slower rate of GF generation, which might be related to their lower sensitivity of two-point dynamic discrimination. Given the slow rate of GF generation and time constraint, the peak GF for children with DCD was lower than that for the control children, but the peak GF of both the groups depended on the time allowed for the performance and the task demand. Both the groups of children cautiously modulated the grip when the cup was filled with water, and graded GF according to the physical property of the cup. We conclude that GF control in children with or without DCD was task dependent.

Are there any cross-ethnic differences in menstrual profiles? A pilot comparative study on Australian and Chinese women with primary dysmenorrhea.

AIM: To explore and compare the features of menstruation, perception and management of menstrual pain between two cohorts of Australian and Chinese women. METHODS: A pilot comparison study was carried out using modified valid menstrual questionnaires. The study included 120 Australian women and 122 Chinese women aged from 18 to 45 years with primary dysmenorrhea. RESULTS: Australian women rated menstrual pain as more intense than Chinese women (8.5 ± 1.5 on a 10-point pain scale vs 7.3 ± 1.8, P < 0.001), duration of pain was 36% longer (3.0 ± 2.5 vs 2.2 ± 0.9 days, P = 0.002) and menarche commenced earlier (12.7 ± 1.5 vs 14.2 ± 1.4 years, P < 0.001). The mean reported menstrual interval was also shorter (29.2 ± 5.3 vs 30.52 ± 3.7, P = 0.020) with heavier overall menstrual flow (P = 0.002) and fewer clots in menstrual blood (83% vs 95.8%, P = 0.001). There was no significant difference in duration of menstruation (5.2 ± 1.3 vs 5.4 ± 1.1 days; P = 0.180). Correlations were found between earlier menarche and increased intensity of menstrual pain (r = -0.16, P = 0.011), and between heavier menstrual flow and increased intensity of menstrual pain (r = 0.19, P = 0.003). CONCLUSION: Evidence from this pilot study suggested that the clinical menstrual presentations in the cohorts of Australian and Chinese women were different. Although the findings are preliminary, evaluating ethnic differences in menstruation and experimental menstrual pain models may not only provide some information about underlying mechanisms but may also predict or explain group differences.
