RESUMEN
BACKGROUND: Dynamic mechanical allodynia (DMA) is both a symptom and a central sensitization sign, yet no standardized method for quantifying the DMA area has been reported. This study aimed to establish psychometric properties for Quantitative Dynamic Allodynography (QDA), a newly developed protocol measuring the DMA area as a percentage of the body surface. METHODS: Seventy-eight patients aged 18-65 diagnosed with chronic complex regional pain syndrome (CRPS) participated in this study. Test-retest reliability was conducted twice, one week apart (N = 20), and inter-rater (N = 3) reliability was conducted on 10 participants. Disease severity (CRPS Severity Score, CSS), pain intensity (VAS), and quality of life (SF-36) measures were utilized to test construct validity. RESULTS: High inter-rater reliability (intraclass correlation coefficient (ICC) = 0.96, p < 0.001) and test-retest reliability (r = 0.98, p < 0.001) were found. Furthermore, the QDA score was found to be correlated with the CSS (r = 0.47, p < 0.001), VAS (r = 0.37, p < 0.001), and the SF-36 physical health total (r = -0.47, p < 0.001) scores. CONCLUSION: The QDA is the first developed reliable and valid protocol for measuring DMA in a clinical setting and may be used as a diagnostic and prognostic measure in clinics and in research, advancing the pain precision medicine approach.

IMPORTANCE: A paucity of studies have focused on pain experiences among people with autism spectrum disorder, particularly those addressing social pain in daily life contexts or learning from the perspective of autistic people. OBJECTIVE: To explore the social pain experience of autistic people. DESIGN: A descriptive qualitative design followed by deductive thematic analysis. Interviews were semistructured to capture the social pain experience, coping strategies, and implications for the participation of autistic people. SETTING: Online interviews using Zoom videoconferencing software. PARTICIPANTS: Fifteen autistic people were recruited for the study using purposeful and criterion sampling. RESULTS: Four primary themes emerged from the data analysis: (1) a definition of social pain and the distinction between social pain and other types of pain; (2) the sources-internal, external, and combined-of social pain; (3) the loneliness outcome, which echoes the gap between the desire for and lack of social contacts; and (4) coping strategies pertaining to the continuum between inward and outward coping strategies to deal with social pain. CONCLUSION AND RELEVANCE: The study indicates the existence of a discrepancy between autistic people's need for social interactions and the social pain they experience. It calls for intervention programs for autistic people to improve their coping strategies and promote their self-acceptance and better inclusion in the community. What This Article Adds: Promoting social functioning is a prime role of occupational therapists, and this article adds a novel theoretical model that contributes to that role. The model represents the social pain experiences of autistic people and their strategies to overcome this phenomenon. Firsthand accounts of autistic people regarding social pain enable a better understanding of their desire to be involved in the social context. This study suggests directions for further intervention programs to assist autistic people in fulfilling their wish for social relationships and enabling their enhanced integration into society. Positionality Statement: We recognize that use of person-first versus identity-first language is a source of debate and controversy. We have chosen to use identity-first language for two reasons. First, studies indicate person with autism is the term least preferred by autistic people (Botha et al., 2021). Second, autistic is the term used by the majority of our participants during interviews.

Background: Difficulty in modulating multisensory input, specifically the sensory over-responsive (SOR) type, is linked to pain hypersensitivity and anxiety, impacting daily function and quality of life in children and adults. Reduced cortical activity recorded under resting state has been reported, suggestive of neuromodulation as a potential therapeutic modality. This feasibility study aimed to explore neurofeedback intervention in SOR. Methods: Healthy women with SOR (n = 10) underwent an experimental feasibility study comprising four measurement time points (T1baseline; T2preintervention; T3postintervention; T4follow-up). Outcome measures included resting-state EEG recording, in addition to behavioral assessments of life satisfaction, attaining functional goals, pain sensitivity, and anxiety. Intervention targeted the upregulation of alpha oscillatory power over ten sessions. Results: No changes were detected in all measures between T1 and T2. Exploring the changes in brain activity between T2 and T4 revealed power enhancement in delta, theta, beta, and gamma oscillatory bands, detected in the frontal region (p = 0.03−<0.001; Cohen's d = 0.637−1.126) but not in alpha oscillations. Furthermore, a large effect was found in enhancing life satisfaction and goal attainment (Cohen's d = 1.18; 1.04, respectively), and reduced pain sensitivity and anxiety trait (Cohen's d = 0.70). Conclusion: This is the first study demonstrating the feasibility of neurofeedback intervention in SOR.

OBJECTIVE: This comparative cross-sectional study aimed to characterize individuals with substance use disorder (SUD) in self-perception of pain sensitivity, experimental auditory aversiveness, and non-noxious sensory responsiveness, as well as examine the associations with SUD. METHODS: Therapeutic community (TC) individuals with SUD (N = 63, male 88.9%) and healthy controls (N = 60, male 86.7%) completed the Pain Sensitivity Questionnaire (PSQ) and the Sensory Responsiveness Questionnaire-Intensity Scale (SRQ-IS), followed by a psychophysical auditory battery, the Battery of Averseness to Sounds (BAS)-Revised. RESULTS: The SUD group scored higher on the PSQ (P < 0.0001), BAS-R aversiveness (P < 0.0001), BAS-R-unpleasantness (P < 0.0001), and on the aftersensation of auditory aversiveness (P < 0.0001) and unpleasantness (P < 0.000). Fifty-four percent of the SUD group vs 11.7% of the control group were identified as having sensory modulation dysfunction (SMD; P < 0.0001). Logistic regression modeling revealed that the SRQ-IS-Aversive score had a stronger relationship, indicating a 12.6-times odds ratio for SUD (P = 0.0002). Finally, a risk score calculated from a linear combination of the logistic regression model parameters is presented based on the PSQ and SRQ. CONCLUSIONS: This is the first study to explore sensory and aversive domains using experimental and self-reporting in situ, revealing pain perception alteration that co-occurs with high prevalence of SMD, specifically of the over-responsive type. Findings may be significant in clinical practice for treating pain, and for expanding therapeutic modalities as part of broader rehabilitation in TC and beyond, to better meet personalized therapy.

BACKGROUND: Coordination is crucial for motor function, yet objective clinical evaluations are limited. We therefore developed and tested the reliability and validity of a low-cost sensorized evaluation of a rhythmic finger task. METHODS: Children with coordination difficulties (n = 24) and typically developing children (n = 24) aged from 5 to 7 years performed the Sensorized Finger Sequencing Test (SFST), a finger sequencing test that records the correct sequence, total time, and the standard deviation (SD) of touch time. Additionally, motor performance tests and parents' reports were applied in order to test the reliability and validity of the SFST. RESULTS: The study group had significantly greater thumb-finger test scores-total time in the dominant hand (p = 0.035) and the SD of the touch time in both dominant (p = 0.036) and non-dominant (p = 0.032) hands. Motor performance tests were not correlated with the SFST. Test-retest reliability in 10 healthy children was found for the SD of touch time in the dominant hand (r = 0.87, p = 0.003). CONCLUSIONS: The SFST was successful in assessing the movement pattern variability reported in children with motor difficulties. This exploratory study indicates that the low-cost SFST could be utilized as an objective measure for the assessment of proprioception components, which currently are overlooked by standardized motor performance assessments.

BACKGROUND: Sensory modulation disorder (SMD) and attention deficit hyperactivity disorder (ADHD) can co-occur and have overlapping symptoms, thus challenging practitioners. This study aimed to phenotypically explore parent-child associations in SMD, and the interplay between SMD- and ADHD-related symptoms in children with SMD and their parents. METHODS: A cross-sectional study examined 70 parents (n = 35 mothers; n = 35 fathers) and their 35 children with and without SMD, aged 4-6 years. Parents completed care-giver reports: The Short Sensory Profile (SSP) and the ADHD Rating Scale, and self-reports: The Sensory Responsiveness Questionnaire (SRQ) and the ADHD Self-Report Scale (ASRS). RESULTS: In the entire sample, we found a mother-offspring correlation between SSP and SRQ-Aversive scores (rs = -0.68; p < 0.001), but no such father-offspring correlation. However, when testing the ADHD Rating Scale and ASRS scores, we found correlations between mothers and offspring (rs = 0.54, p = 0.0008), and between fathers and offspring (rs = 0.34, p = 0.0494). In the entire sample a high correlation was found between SSP and ADHD Rating Scale scores (rs = -0.837, p < 0.001). We further found a high correlation in mothers (rs = 0.70, p < 0.001), and a moderate correlation in fathers (rs = 0.40, p = 0.019) between SRQ-Aversive and ASRS scores. CONCLUSIONS: Novel findings reveal that parents-offspring heritability patterns differ in both these related conditions. These may contribute to familial practice and research.

OBJECTIVE: People with sensory overresponsiveness (SOR) perceive nonpainful stimuli as noxious and demonstrate hyperalgesia and lingering sensation to laboratory pain stimuli. Electroencephalography (EEG) of cortical activity at rest is widely used to explore endophenotypes but has not yet been tested in people with SOR. Therefore, we investigated the characteristics of resting-state EEG in participants with SOR. METHOD: Resting-state EEG (5-min, eyes-closed recording) was compared in participants with (n = 9) and without (n = 12) SOR. RESULTS: Participants with SOR demonstrated a global reduction of the EEG activity, including significantly lower θ and α1 activity as well as faster peak α frequency. Higher sensory-responsiveness scores were associated with high peak α power in participants without SOR. CONCLUSION: Reduced α activity is commonly interpreted as an electrophysiological indicator of arousal and sensitivity to pain. The EEG pattern of response may partly explain the reported ongoing daily alertness to environmental stimuli in participants with SOR.

OBJECTIVE: Chronic pain patients show hypersensitivity to sensory nonpainful stimuli. Sensory over-responsiveness (SOR) to innocuous daily stimuli, experienced as painful, is prevalent in 10% of the healthy population. This altered sensory processing may be an expression of overfacilitation, or a less efficient pain-inhibitory process in the pain pathways. We therefore aimed to investigate specifically the pain-inhibitory system of subjects with SOR who are otherwise healthy, not studied as of yet. METHODS: Thirty healthy subjects, divided into an SOR group (n = 14) and a non-SOR group (n = 16) based on responses to the Sensory Responsiveness Questionnaire, were psychophysically tested in order to evaluate (1) hyperalgesic responses; (2) adaptation/sensitization to 14 phasic heat stimuli; (3) habituation; (4) 6-minute after-sensations; and (5) conditioned pain modulation (CPM) (ie, phasic heat stimuli applied with and without hand immersion in a hot water bath). RESULTS: The SOR group differed from the non-SOR group in (1) a steeper escalation in NPS ratings to temperature increase (P = 0.003), indicating hyperalgesia; (2) increased sensitization (P < 0.001); (3) habituation responses (P < 0.001); (4) enhanced pain ratings during the after-sensation (P = 0.006); and (5) no group difference was found in CPM. CONCLUSIONS: SOR is associated with a pronociceptive state, expressed by amplification of experimental pain, yet with sufficient inhibitory processes. Our results support previous findings of enhanced facilitation of pain-transmitting pathways but also reveal preserved inhibitory mechanisms, although they were slower to react.

AIM: To explore relationships between sensory responsiveness, anxiety, and ritual behaviors in boys with typical and atypical sensory responsiveness. METHOD: Forty-eight boys, ages 5-9 participated in the study (28 boys with atypical sensory responsiveness and 20 controls). Atypical sensory responsiveness was defined as a score of ≤154 on the Short Sensory Profile. Parents completed the Sensory Profile, the Screen for Child Anxiety Related Emotional Disorders, and the Childhood Routines Inventory. RESULTS: Children with atypical sensory responsiveness had significantly higher levels of anxiety and a higher frequency of ritual behaviors than controls. Atypical sensory responsiveness was significantly related to both anxiety and ritual behaviors, with anxiety mediating the relationship between sensory modulation and ritual behaviors. CONCLUSIONS: The findings elucidate the potential consequences of atypical sensory responsiveness and could support the notion that ritual behaviors develop as a coping mechanism in response to anxiety stemming from primary difficulty in modulating sensory input.

Schizophrenia is considered to be an extreme mental health disturbance that affects a person's well-being and participation in everyday activities. Participation in meaningful everyday occupations is an important component of recovery from mental illness, the ultimate goal of mental health services. The participation restrictions of people with schizophrenia have been widely investigated through different factors, such as illness symptoms and course, cognition, and demographic data; however, the resulting explanations were incomplete. The purpose of the study was to explore the contribution of sensory modulation (SM), in addition to cognition and schizophrenia symptoms, to participation in daily life activities of people with schizophrenia. Forty nine in-patients with schizophrenia (study group) and 32 adults without mental illness (control group) comprised the study. They were assessed for their participation patterns, sensory modulation processes, cognitive functioning and symptoms severity. Results indicate significant differences between the study groups in most measurements addressed: participation (diversity and satisfaction), sensory modulation scores (intensity of the response and frequency of response), and cognitive measurements. The most contributive parameters for the prediction of participation dimensions among people with schizophrenia were negative symptoms severity and general cognitive status. In conclusion, people with schizophrenia experience SM disorder with an under responsive tendency. However the complex condition of schizophrenia dominates its influence on participation dimensions.

BACKGROUND: Substance use disorder (SUD) is associated with executive function (EF) deficits and sensory modulation dysfunction (SMD). Yet, these deficits are not addressed therapeutically. This study aims to examine the effectiveness of the Functional-Cognitive and Sensory Treatment (F-CaST) compared to standard care to improve everyday performance and behavior and length of stay at the therapeutic community (TC) in individuals with SUD. In addition, to assess the improvement in EF, sensory modulation, participation, self-efficacy, life satisfaction, and use of strategies within and between groups. Satisfaction with F-CaST will also be assessed. METHODS: Forty-eight participants from a community of men in a TC, aged 18-45 years will be randomly allocated to (i) F-CaST-(experimental group) providing sensory and EF strategies for improving daily function; (ii) standard care (control group) as provided in the TC. Assessments will be conducted by assessors blind to group allocation at 4 time points: T1- pre-intervention; T2- post-intervention; T3- 1-month follow-up; and T4- 3-month follow-up. Primary outcome measures will be everyday performance, assessed by the Canadian Occupational Performance Measure (COPM), behavior and length of stay in the TC; secondary outcome measures will assess EF, SMD. Semi-structured in-depth qualitative interviews will be conducted at T1, T2 and T4. DISCUSSION: We hypothesize that F-CaST will lead to improved everyday performance and longer length of stay in the TC, compared to the control group. If F-CaST will prove to be effective, cognitive and sensory strategies may be incorporated as an adjunctive intervention in SUD rehabilitation.

BACKGROUND: Exclusive breastfeeding (EBF) is recommended for the first 6 months of life, yet EBF rates at 6 months (T3) in most developed countries are low. Painful and nonpainful sensory stimuli processing is linked, and while pain has been suggested to restrict breastfeeding, its coupling with sensory over-responsiveness (SOR) in relation to breastfeeding has not yet been reported. OBJECTIVE: We aimed to explore whether breastfeeding-related pain, SOR, and general pain sensitivity predict nonexclusive breastfeeding (NEBF) at T3. STUDY DESIGN: In this prospective study, participants were recruited at 2 days postpartum (enrollment). For the assessment of breastfeeding-related pain, participants completed the visual analogue scale and the Short-Form McGill Pain Questionnaire at enrollment, and at 6 weeks after birth. At T3, they completed the Pain Sensitivity Questionnaire and the Sensory Responsiveness Questionnaire-Intensity Scale and then provided information about their breastfeeding status. Participants were divided into two groups accordingly: EBF and NEBF. RESULTS: A total of 164 participants were reached at T3: EBF (n = 105) and NEBF (n = 59). The incidence of SOR was significantly higher among NEBF compared with EBF participants (25.4% vs. 11.4%; p = .020). Between enrollment and 6 weeks after birth, 72.3% of the EBF participants had reported a ≥30% pain reduction, compared with 44.8% of the NEBF participants (p = .001). Logistic regression modeling revealed that both breastfeeding-related pain reduction and SOR predicted NEBF at T3 (p < .001), indicating a 3.2 times (p = .001) and 2.5 times (p = .041) odds ratio for NEBF, respectively. CONCLUSIONS: SOR and sustained breastfeeding-related pain predict NEBF at T3 and may emerge as substantial breastfeeding barriers.

BACKGROUND: Attention deficit hyperactivity disorder (ADHD) is a complex neurological condition interfering with family relationships and co-regulation capabilities. Therefore, exploring factors underpinning parental co-regulation ability is crucial for future fostering relationships in families of children with ADHD. OBJECTIVE: This preliminary study aims to characterize and compare the executive-functions, anxiety, self-efficacy, and sensory modulation in mothers of children with and without ADHD. METHOD: Mothers of children with (study group) and without (control-comparison, group) ADHD completed online self-reports, measuring executive-functions; parental self-efficacy; anxiety; and sensory modulation. RESULTS: The study group (N = 40) had lower self-efficacy compared to the control group (N = 27; p = 0.018), and the control group had lower sensory responsiveness (p = 0.025). Within both groups the Behavior Rating Inventory of Executive Function-Adult (BRIEF-A) Global Executive Function Composite score (GEC) and the Beck Anxiety Inventory (BAI) were moderately correlated. Further, within the study group correlations were found between the BRIEF-A-GEC and the Sensory Responsiveness Questionnaire (SRQ)-Aversive scores (r = 0.37, p ≤ 0.01), and between the BRIEF-A Behavioral-Rating-Index and the parental self-efficacy scores (r = 0.31, p ≤ 0.05). Within the control group, negative correlations were found between the BRIEF-A-GEC and SRQ-Hedonic scores (r= -0.44, p < 0.05). CONCLUSION: Self-efficacy, executive-functions, high sensory responsiveness and anxiety traits are interwoven and may impact parental co-regulation ability.
RESUMEN
BACKGROUND: War is a highly traumatogenic experience that may result in trauma-related symptoms during exposure. Although most individuals exhibit recovery after the trauma ends, symptomatology during exposure may serve as an initial indicator underlying symptomatology at the posttraumatic phase, hence the imperative to identify risk factors for trauma-related symptoms during the peritraumatic phase. While research has uncovered several factors associated with peritraumatic distress, such as age, gender, history of mental disorder, perceived threat, and perceived social support, the role of sensory modulation has not been explored. METHOD: To address this gap, 488 Israeli citizens were assessed using an online survey for sensory modulation and trauma-related symptoms during rocket attacks. RESULTS: Analyses revealed that while the association between high sensory responsiveness and elevated levels of specific trauma-related symptoms is somewhat weak (0.19
High sensory responsiveness was related to trauma-related symptoms.Low sensory responsiveness was unrelated to trauma-related symptoms.The risk for elevated trauma-related symptoms during exposure was doubled for each increase in high sensory-responsiveness score.

Background: Although exclusive breastfeeding (EBF) is recommended for the first 6 months of life, breastfeeding rates in most developed countries are low. Sensory over-responsivity (SOR) has been found to interfere with infant and childcare, development, and routines, but has not yet been examined as a breastfeeding barrier. The aim of this study was to explore the association between infant sensory responsiveness and EBF and whether it can predict EBF cessation prior to 6 months of age. Methods: In this cohort prospective study participants were 164 mothers and their infants recruited 2 days after birth in a maternity ward between June 2019 and August 2020. At this time, participating mothers completed a demographic and delivery information questionnaire. At 6 weeks after birth, the mothers completed the Infant Sensory Profile 2 (ISP2), reporting their infants' sensory responsiveness in daily activities. At 6 months, infants' sensory responsiveness was assessed using the Test of Sensory Functions in Infants (TSFI) and the Bayley Scales of Infant and Toddler Development-3rd Edition (Bayley-III) was administered. Additionally, mothers provided information about their breastfeeding status and were divided into two groups accordingly: EBF and non-EBF (NEBF). Results: The incidence of atypical sensory responsiveness (mostly of the SOR type) at 6 weeks was twice as high among NEBF infants than EBF infants (36.2% vs. 17%, χ2=7.41, P=0.006). Significant group differences were found in the ISP2 touch section (F=10.22, P=0.002). In addition, NEBF infants displayed more SOR behaviors than EBF infants in the TSFI deep touch (F=2.916, P=0.001) and tactile integration subtests (F=3.095, P<0.001), and had lower scores in the adaptive motor functions subtest (F=2.443, P=0.013). Logistic regression modeling revealed that ISP2 at 6 weeks (typical vs. atypical) and TSFI total score at 6 months predicted 28% of NEBF at 6 months (χ2=23.072, P=0.010). Conclusions: Infant atypical sensory responsiveness, predominantly of the SOR type, was found to predict NEBF at 6 months after birth. This study contributes to the understanding of EBF barriers, highlighting the importance of early identification of SOR in infants. Findings may suggest developing early sensory interventions and providing individualized breastfeeding support tailored to the infant's unique sensory profile.
RESUMEN
BACKGROUND: Chronic fatigue syndrome (CFS) is characterised by extreme fatigue, as well as physical and cognitive symptoms. CFS is thrice as prevalent in women than in men. OBJECTIVE: To compare women with and without CFS concerning social support and participation in daily routine occupations, and to assess the relationships between the two variables among women with CFS. METHODS: This study included 110 women aged 24-69: 41 were diagnosed with CFS and 64 were not diagnosed with CFS. Participants completed the Occupational Questionnaire and the Medical Outcomes Study (MOS) Social Support Survey. RESULTS: Women with CFS reported lower participation in instrumental activities of daily living and work occupations than women without CFS. However, they spend more time resting and enjoying it. In addition, they reported less social support than women without CFS. Positive correlations were found between the number of close friends and time spent in play and leisure occupations and a negative correlation with sleep/rest. CONCLUSIONS: Women with CFS participate less in IADL and work occupations and more in rest/sleep than women without CFS and their social support is attenuated. SIGNIFICANCE: Intervention plans should be developed for women with CFS, focussing on expanding their participation while considering their social support resources.

ABSTRACT: Excitatory-inhibitory (E/I) imbalance is a mechanism that underlies autism spectrum disorder, but it is not systematically tested for pain processing. We hypothesized that the pain modulation profile (PMP) in autistic individuals is characterized by less efficient inhibitory processes together with a facilitative state, indicative of a pronociceptive PMP. Fifty-two adults diagnosed with autism and 52 healthy subjects, age matched and sex matched, underwent quantitative sensory testing to assess the function of the (1) pain facilitatory responses to phasic, repetitive, and tonic heat pain stimuli and (2) pain inhibitory processes of habituation and conditioned pain modulation. Anxiety, pain catastrophizing, sensory, and pain sensitivity were self-reported. The autistic group reported significantly higher pain ratings of suprathreshold single ( P = 0.001), repetitive (46°C- P = 0.018; 49°C- P = 0.003; 52°C- P < 0.001), and tonic ( P = 0.013) heat stimuli that were cross correlated ( r = 0.48-0.83; P < 0.001) and associated with sensitivity to daily life pain situations ( r = 0.39-0.45; P < 0.005) but not with psychological distress levels. Hypersensitivity to experimental pain was attributed to greater autism severity and sensory hypersensitivity to daily stimuli. Subjects with autism efficiently inhibited phasic but not tonic heat stimuli during conditioned pain modulation. In conclusion, in line with the E/I imbalance mechanism, autism is associated with a pronociceptive PMP expressed by hypersensitivity to daily stimuli and experimental pain and less-efficient inhibition of tonic pain. The latter is an experimental pain model resembling clinical pain. These results challenge the widely held belief that individuals with autism are indifferent to pain and should raise caregivers' awareness of pain sensitivity in autism.

Although exclusive breastfeeding is recommended for the first 6 months of life, breastfeeding rates are low. Motor skills and ADHD-related characteristics have not yet been examined as breastfeeding barriers. The aim of this study was to explore whether mothers' and infants' motor skills, mothers' ADHD-related characteristics and infants' temperament are associated with exclusive breastfeeding at 6 months after birth. Participants were 164 mothers and their infants recruited 2 days after birth. Mothers completed a demographic and delivery information questionnaire, the Infant Feeding Intentions Scale and the Iowa Infant Feeding Attitude Scale. At 6 months, mothers completed the Adult DCD (developmental coordination disorder)/Dyspraxia Checklist, the Adult ADHD (attention deficit hyperactivity disorder) Self-Report Scale Symptom Checklist-v1.1, and the Infant Characteristics Questionnaire, and provided information about their breastfeeding status. They were then divided into two groups accordingly: EBF (exclusive breastfeeding) and NEBF (non-exclusive breastfeeding). Infants were observed using the Test of Sensory Functions in Infants and the Alberta Infant Motor Scale. At 6 months, NEBF mothers reported higher prevalence of DCD (10.2% vs. 1.9%, χ2 = 5.561, p = 0.018) and ADHD (20.3% vs. 8.6%, χ2 = 4.680, p = 0.030) compared to EBF mothers. EBF infants demonstrated better motor coordination (t = 2.47, p = 0.016, d = 0.511), but no temperament differences compared to NEBF infants. Maternal DCD, ADHD and poor infant motor coordination are associated with non-exclusive breastfeeding and may become exclusive breastfeeding barriers. These findings may assist in identifying women at risk of not exclusively breastfeeding and encourage tailoring interventions for achieving higher exclusive breastfeeding rates.

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) and sensation-seeking, a trait characterized by risk-related behaviors, have been recognized as risk factors in substance use disorder (SUD). Though ADHD co-occurs with sensory modulation dysfunction (SMD), SMD has scarcely been explored in SUD. Thus, this study aimed to characterize ADHD symptomology, sensation-seeking, and SMD, as well as to explore their contribution to SUD likelihood. METHODS: A cross sectional two-group comparative study including therapeutic community residents with SUD (n = 58; study group) and healthy individuals (n = 62; comparison group) applying the MOXO continuous performance test (MOXO-CPT) evaluating ADHD-related symptoms. In addition, participants completed the ADHD Self-Report Scale-Version 1.1 for ADHD screening; the Brief Sensation Seeking Scale quantifying risk-taking behaviors; and the Sensory Responsiveness Questionnaire-Intensity Scale for identifying SMD. RESULTS: The study group demonstrated higher SMD incidence (53.57% vs. 14.52%) and lower performance in three MOXO-CPT indexes: Attention, Impulsivity, and Hyperactivity, but not in Timing, compared to the comparison group. Sensory over-responsiveness had the strongest relationship with SUD, indicating 27-times increased odds for SUD (95% CI = 5.965, 121.216; p ≤ 0.0001). A probability risk index is proposed. CONCLUSION: We found SMD with the strongest relation to SUD exceeding that of ADHD, thus contributing a new perspective for developing future therapeutic modalities. Our findings highlight the need to address SMD above and beyond ADHD symptomology throughout the SUD rehabilitation.

Introduction: Misophonia and sensory over-responsiveness (SOR) share physiological and psychological symptoms. While individuals with SOR demonstrate pain perception alterations, these were not explored in misophonia. Methods: This exploratory study comprised thirty healthy adults with (n = 15; based on the Misophonia Questionnaire) and without misophonia. The Sensory Responsiveness Questionnaire (SRQ) was used for evaluating sensory responsiveness. In addition, psychophysical tests were applied for quantification of: (i) stimulus-response function of painful stimuli, (ii) the individual perceived pain intensity, (iii) pain modulation efficiency, (iv) auditory intensity discrimination capability, and (v) painful and unpleasantness responses to six ecological daily sounds using the Battery of Aversiveness to Sounds (BAS). Results: Individuals with misophonia reported higher scores in the SRQ-Aversive (p = 0.022) and SRQ-Hedonic (p = 0.029) scales as well as in auditory (p = 0.042) and smell (p = 0.006) sub-scales, indicating higher sensory responsiveness. Yet they were not identified with the SOR type of sensory modulation dysfunction. Groups did not differ in the pain psychophysical tests, and in auditory discrimination test scores (p > 0.05). However, in the misophonia group the BAS evoked higher pain intensity (p = 0.046) and unpleasantness (p <0.001) ratings in the apple biting sound, and higher unpleasantness rating in the scraping a dish sound (p = 0.007), compared to the comparison group. Conclusion: Findings indicate increased sensory responsiveness in individuals with misophonia, yet not defined as SOR. Thus, this suggests that misophonia and SOR are two distinct conditions, differing in their behavioral responses to painful and non-painful stimuli.
