The Functional-Cognitive and Sensory Treatment (F-CaST) to improve rehabilitation outcomes of individuals with substance use disorder: a study protocol for a mixed-method randomized controlled trial

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.

Breastfeeding-related Pain, Sensory Over-responsiveness, and Exclusive Breastfeeding at 6 Months: A Prospective Cohort Study

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.

Associations between daily routines and social support among women with chronic fatigue syndrome

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.

Quantitative Dynamic Allodynograph-A Standardized Measure for Testing Dynamic Mechanical Allodynia in Chronic Limb Pain

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.

Exploring Co-Regulation-Related Factors in the Mothers of ADHD Children-Proof of Concept Study

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.

Does infant sensory responsiveness explain exclusive breastfeeding 6 months after birth?-a cohort prospective study

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-3^rd 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.

Indifference or hypersensitivity? Solving the riddle of the pain profile in individuals with autism

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.

"Feeling Unwanted, When Nobody Wants You Around": Perceptions of Social Pain Among People With Autism

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.

Sensory modulation and trauma-related symptoms during rocket attacks

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<r<.0.22), it serves as a major risk factor for developing trauma-related symptoms during the peritraumatic phase in general. Specifically, the risk for elevated symptoms was doubled (OR = 2.11) for each increase in the high sensory-responsiveness score, after controlling for age, gender, history of mental disorder, perceived threat, and perceived social support.

LIMITATIONS

This study relied on convenience sampling and a cross-sectional design.

CONCLUSIONS

The present findings suggest that sensory modulation evaluation may serve as an important screening tool for identifying individuals who are vulnerable to trauma-related symptoms during the peritraumatic phase, and that implementing sensory modulation strategies as part of preventative interventions for PTSD might be effective.

Opening a window into the riddle of misophonia, sensory over-responsiveness, and pain

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.

“When I’m in Pain, Everything Is Overwhelming”: Implications of Pain in Adults With Autism on Their Daily Living and Participation

Pain sensation in autism spectrum disorder (ASD) has been a growing research field in the last two decades. Existing pain research has focused on pain sensitivity, suggesting either hyposensitivity or hypersensitivity to pain in individuals with ASD. However, research about other aspects of pain experience is scarce. Moreover, most pain-related research in ASD focused on quantitative measures, such as neuroimaging or parental reports. Instead, this paper aimed to illuminate the various aspects of pain experience as perceived by adults with ASD. Its descriptive qualitative research design incorporated semi-structured interviews and deductive thematic analysis. This phenomenological approach captured the subjective pain experience through the lens of people with ASD. Four primary themes emerged from the data: (a) physical pain experience, including the sequence of pain sensitivity, pain awareness, pain-related emotional aspects, and pain communication; (b) direct and indirect coping strategies; (c) function and participation outcomes; and (d) suggestions for Healthcare Providers. The findings echo the crucial role of pain awareness and communication in the pain experience of people with ASD. These two factors have been reported as profoundly influencing coping strategies, function, and participation. The results emphasize the need to expand the exploration of pain in this population, calling for greater understanding, and listening to this population’s unique pain profiles and experiences to promote better-suited evaluation, diagnosis, and intervention in pain conditions.

The Role of Motor Coordination, ADHD-Related Characteristics and Temperament among Mothers and Infants in Exclusive Breastfeeding: A Cohort Prospective Study

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.

Neurofeedback Therapy for Sensory Over-Responsiveness-A Feasibility Study

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 (T1—baseline; T2—preintervention; T3—postintervention; T4—follow-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.

Attention-Deficit/Hyperactivity Disorder Symptoms, Sensation-Seeking, and Sensory Modulation Dysfunction in Substance Use Disorder: A Cross Sectional Two-Group Comparative Study

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.

High Sensory Responsiveness in Older Adults is Associated with Walking Outside but Not Inside: Proof of Concept Study

Background and Purpose

Reduced mobility and a higher risk of falls among older adults are related to aging-associated sensory alteration. Sensory responsiveness (SR) has been found to be strongly correlated with postural control in studies on young adults in stimulating environments; however, SR has not been studied in the context of mobility among older adults, despite its potential to enhance fall risks. The aim of the current study is to characterize the associations between SR and gait under single and dual-task (ST, DT) conditions inside and outside the laboratory.

Methods

Twenty-six community-dwelling older adults (age 70.3 ± 4.6 years, 65.4% women) participated in this cross-sectional study. Gait variables were measured using the APDM system under single and dual task conditions, in a quiet corridor inside and in an ecological (outside) environment. SR was evaluated using the SR questionnaire and cognition was assessed with the Trail-Making Test and the Montreal Cognitive Assessment.

Results

SR was negatively associated with gait speed during ST (r_s = −0.491, p < 0.05) and DT (r_s = −0.528, p < 0.01) outside and with ST gait speed inside (r_s = −0.528, p < 0.01). SR was positively associated with gait variability under DT (r_s = 0.41, p < 0.05) and with DT cost (r_s = 0.44, p < 0.05) only outside.

Conclusion

SR may play an important role in understanding mobility deterioration throughout the aging process, especially outside, illuminating the importance of SR evaluation among older adults during mobility assessment. Therefore, accounting for SR in gait research may contribute to a better understanding of mobility decline throughout the aging process.

Perceived Sensitivity to Pain and Responsiveness to Non-noxious Sensation in Substance Use Disorder

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.

An Instrumented Assessment of a Rhythmic Finger Task among Children with Motor Coordination Difficulties

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.

Multi-sensory Responsiveness and Personality Traits Predict Daily Pain Sensitivity

Background: A continuous effort has been devoted to identifying factors that contribute to individual differences in pain perception. Amongst the personality traits, Neuroticism is assumed to be the most significant moderator of experimental and clinical pain. Multi-sensory responsiveness to daily sensations has been shown to be associated with pain perception. Yet, neither the relationship between personality traits and multi-sensory responsiveness nor the impact of both these factors to pain perception have been examined. Thus, this study aims to explore the contribution of both multi-sensory responsiveness and personality traits to pain perception in a daily context.

Methods: A community-based sample of 204 adults completed the Sensory Responsiveness Questionnaire-Intensity Scale (SRQ-IS); the Big Five Inventory (BFI); and the Pain Sensitivity Questionnaire (PSQ).

Results: The partial eta-square demonstrated that the SRQ-IS Aversive sub-scale score had the strongest relationship with the PSQ-Total score, accounting for 9% of the variation. The regression coefficient relating PSQ-Total score with SRQ-IS Aversive, and BFI sub-scales of Extraversion, Neuroticism and Openness-to-Experience scores was found to be r = 0.39 (p < 0.0001), accounting for 16% of the variance, and yielding a large effect size.

Discussion: To the best of our knowledge this is the first study to report on the interplay between aversive responsiveness to daily sensations and personality traits of Neuroticism, Openness-to-Experience, and Extraversion as contributing factors to daily pain sensitivity, amongst which aversive responsiveness was found as the major contributing factor. This study may broaden the understanding of the pain experience variability, both in practice and in experimental research.

Sensory Modulation Disorder (SMD) and Pain in Substance-Use Disorder (SUD)

Date Presented 04/04/19

SUD impacts the individual and his family's daily occupations while posing a massive health and societal concern. OTs may contribute a unique perspective in understanding this phenomenon. This is the first study to explore pain sensitivity and SMD in SUD. Findings demonstrate that while pain and SMD coexist, SMD may serve as a risk factor for having SUD, thus indicating a potential additive value for OTs in SUD therapy.

Sensory Over-Responsive (SOR) Individuals Show a “Nonresting” Brain

Date Presented 04/04/19

This is the first study to demonstrate abnormal neurophysiological resting state activity in SOR individuals under task-free. Findings may indicate a fundamental deficiency in brain activity that may underlie the daily difficulties experienced by individuals with SOR. Moreover, the brain activity pattern found validates previous findings associating SOR and pain sensitivity. This study may suggest a new direction for a remedial approach using neurofeedback in individuals with SOR.

Participation and Life Satisfaction Among Women With Chronic Fatigue Syndrome (CFS)

Date Presented 04/04/19

The purpose of this study was to compare women with and without Chronic Fatigue Syndrome (CFS) in social support, participation in occupations, and life satisfaction. The study included 110 women: 41 diagnosed with CFS and 69 healthy controls. Findings demonstrate that women with CFS report lower participation in occupations, less satisfaction with life, and less social support compared to healthy women. These findings suggest that women with CFS may benefit from OT intervention.

An exploratory study of parent-child association in sensory modulation disorder involving ADHD-related symptoms

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.

Sensory Modulation Disorder (SMD) and Pain: A New Perspective

Sensory modulation disorder (SMD) affects sensory processing across single or multiple sensory systems. The sensory over-responsivity (SOR) subtype of SMD is manifested clinically as a condition in which non-painful stimuli are perceived as abnormally irritating, unpleasant, or even painful. Moreover, SOR interferes with participation in daily routines and activities (Dunn, 2007; Bar-Shalita et al., 2008; Chien et al., 2016), co-occurs with daily pain hyper-sensitivity, and reduces quality of life due to bodily pain. Laboratory behavioral studies have confirmed abnormal pain perception, as demonstrated by hyperalgesia and an enhanced lingering painful sensation, in children and adults with SMD. Advanced quantitative sensory testing (QST) has revealed the mechanisms of altered pain processing in SOR whereby despite the existence of normal peripheral sensory processing, there is enhanced facilitation of pain-transmitting pathways along with preserved but delayed inhibitory pain modulation. These findings point to central nervous system (CNS) involvement as the underlying mechanism of pain hypersensitivity in SOR. Based on the mutual central processing of both non-painful and painful sensory stimuli, we suggest shared mechanisms such as cortical hyper-excitation, an excitatory-inhibitory neuronal imbalance, and sensory modulation alterations. This is supported by novel findings indicating that SOR is a risk factor and comorbidity of chronic non-neuropathic pain disorders. This is the first review to summarize current empirical knowledge investigating SMD and pain, a sensory modality not yet part of the official SMD realm. We propose a neurophysiological mechanism-based model for the interrelation between pain and SMD. Embracing the pain domain could significantly contribute to the understanding of this condition’s pathogenesis and how it manifests in daily life, as well as suggesting the basis for future potential mechanism-based therapies.

Resting-State Electroencephalography in Participants With Sensory Overresponsiveness: An Exploratory Study

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.

Sensory modulation, physical activity and participation in daily occupations in young children

BACKGROUND.

Physical activity (PA) promotes children's health. While sensory processing is integral to motor output, research regarding PA in children with sensory processing challenges is sparse.

PURPOSE.

This study aimed to examine the PA pattern and its association with daily life participation of children with sensory processing challenges.

METHOD.

Forty-four children ages 5 to 7 years were divided into the study group (children with sensory processing challenges; n = 22; 16 males) and an age-matched typically developing control group ( n = 22; nine males). Parents completed the Short Sensory Profile, a demographic questionnaire, Participation in Childhood Occupations Questionnaire, and Participation in Physical Activity and Sedentary Behavior Questionnaire-Modified. Data were analyzed using descriptive statistics and correlational analysis.

FINDINGS.

Structured PA was reported in 45% and 77% of the study and control groups, respectively ( p = .030). In the study group, the level of participation in PA was found to be significantly correlated with play and leisure activities.

IMPLICATIONS.

Promoting structured and group PA opportunities may be important for children with sensory processing challenges.

Sensory modulation dysfunction is associated with Complex Regional Pain Syndrome

OBJECTIVE

Complex Regional Pain Syndrome (CRPS), a chronic pain condition, develops mainly after limb trauma and severely inhibits function. While early diagnosis is essential, factors for CRPS onset are elusive. Therefore, identifying those at risk is crucial. Sensory modulation dysfunction (SMD), affects the capacity to regulate responses to sensory input in a graded and adaptive manner and was found associated with hyperalgesia in otherwise healthy individuals, suggestive of altered pain processing.

AIM

To test SMD as a potential risk factor for CRPS.

METHODS

In this cross-sectional study, forty-four individuals with CRPS (29.9±11 years, 27 men) and 204 healthy controls (27.4±3.7 years, 105 men) completed the Sensory Responsiveness Questionnaire-Intensity Scale (SRQ-IS). A physician conducted the CRPS Severity Score (CSS), testing individuals with CRPS.

RESULTS

Thirty-four percent of the individuals with CRPS and twelve percent of the healthy individuals were identified to have SMD (χ2 (1) = 11.95; p<0.001). Logistic regression modeling revealed that the risk of CRPS is 2.68 and 8.21 times higher in individuals with sensory over- and sensory under-responsiveness, respectively, compared to non-SMD individuals (p = 0.03 and p = 0.01, respectively).

CONCLUSIONS

SMD, particularly sensory under-responsiveness, might serve as a potential risk factor for CRPS and therefore screening for SMD is recommended. This study provides the risk index probability clinical tool a simple evaluation to be applied by clinicians in order to identify those at risk for CRPS immediately after injury. Further research is needed.

Assessment of Responsiveness to Everyday Non-Noxious Stimuli in Pain-Free Migraineurs With Versus Without Aura

Migraineurs with aura (MWA) express higher interictal response to non-noxious and noxious experimental sensory stimuli compared with migraineurs without aura (MWoA), but whether these differences also prevail in response to everyday non-noxious stimuli is not yet explored. This is a cross-sectional study testing 53 female migraineurs (30 MWA; 23 MWoA) who underwent a wide battery of noxious psychophysical testing at a pain-free phase, and completed a Sensory Responsiveness Questionnaire and pain-related psychological questionnaires. The MWA group showed higher questionnaire-based sensory over-responsiveness (P = .030), higher magnitude of pain temporal summation (P = .031) as well as higher monthly attack frequency (P = .027) compared with the MWoA group. Overall, 45% of migraineurs described abnormal sensory (hyper- or hypo-) responsiveness; its incidence was higher among MWA (19 of 30, 63%) versus MWoA (6 of 23, 27%, P = .012), with an odds ratio of 3.58 for MWA. Sensory responsiveness scores were positively correlated with attack frequency (r = .361, P = .008) and temporal summation magnitude (r = .390, P = .004), both regardless of migraine type. MWA express higher everyday sensory responsiveness than MWoA, in line with higher response to experimental noxious stimuli. Abnormal scores of sensory responsiveness characterize people with sensory modulation dysfunction, suggesting possible underlying mechanisms overlap, and possibly high incidence of both clinical entities.

PERSPECTIVE

This article presents findings distinguishing MWA, showing enhanced pain amplification, monthly attack frequency, and over-responsiveness to everyday sensations, compared with MWoA. Further, migraine is characterized by a high incidence of abnormal responsiveness to everyday sensation, specifically sensory over-responsiveness, that was also found related to pain.

Sensory Over-Responsiveness among Healthy Subjects is Associated with a Pronociceptive State

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.

Relationships among Sensory Responsiveness, Anxiety, and Ritual Behaviors in Children with and without Atypical Sensory Responsiveness

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.

Date Presented 3/30/2017

This is the first study to test phenotype relationships and manifestations in parents of children with sensory modulation disorder (SMD), demonstrating an SMD relationship between mothers and their offspring but not fathers. Interestingly, reduced quality of life of both parents was most affected by their own attention deficit hyperactivity disorder.

Atypical Sensory Modulation and Psychological Distress in the General Population

OBJECTIVE

Atypical sensory modulation (ASM) is characterized by over- or underresponsiveness to sensory stimuli in one or more sensory systems. Faulty sensory information processing could result in anxiety. Because the relation between ASM and psychological distress has not been examined, we explored psychological distress and ASM in the general population.

METHOD

A community-based sample of 204 adults (105 men; mean age = 27.4 yr, standard deviation = 3.71) completed the Sensory Responsiveness Questionnaire--Intensity Scale (SRQ-IS; Bar-Shalita, Seltzer, Vatine, Yochman, & Parush, 2009); the Brief Symptom Inventory (BSI; Derogatis & Coons, 1993); and the Short Form--36 Health Survey, Version 2 (SF-36; Ware, Kosinski, & Gandek, 2005).

RESULTS

The ASM group displayed considerably more distress symptoms than the comparison group. Multivariate linear regression showed SRQ-IS and SF-36 scores as significant predictors of BSI score (r = .64).

CONCLUSION

ASM may be a risk factor for developing other mental health concerns.

Ecological aspects of pain in sensory modulation disorder

BACKGROUND

Sensory Modulation Disorder (SMD) interferes with the daily life participation of otherwise healthy individuals and is characterized by over-, under- or seeking responsiveness to naturally occurring sensory stimuli. Previous laboratory findings indicate pain hyper-sensitivity in SMD individuals suggesting CNS alteration in pain processing and modulation. However, laboratory studies lack ecological validity, and warrant clinical completion in order to elicit a sound understanding of the phenomenon studied. Thus, this study explored the association between sensory modulation and pain in a daily life context in a general population sample.

METHODS

Daily life context of pain and sensations were measured in 250 adults (aged 23-40 years; 49.6% males) using 4 self-report questionnaires: Pain Sensitivity Questionnaire (PSQ) and Pain Catastrophizing Scale (PCS) to evaluate the sensory and cognitive aspects of pain; the Sensory Responsiveness Questionnaire (SRQ) to appraise SMD; and the Short Form - 36 Health Survey, version 2 (SF36) to assess health related Quality of Life (QoL).

RESULTS

Thirty two individuals (12.8%) were found with over-responsiveness type of SMD, forming the SOR-SMD group. While no group differences (SOR-SMD vs. Non-SMD) were found, low-to-moderate total sample correlations were demonstrated between the SRQ-Aversive sub-scale and i) PSQ total (r=0.31, p<0.01) and sub-scales scores (r=0.27-0.28, p<0.01), as well as ii) PCS total and the sub-scales of Rumination and Helplessness scores (r=0.15, p<0.05). PSQ total and sub-scale scores were more highly correlated with SRQ-Aversive in the SOR-SMD group (r=0.57-0.68, p=0.03-<0.01) compared to Non-SMD group. The Physical Health - Total score (but not the Mental Health - Total) of the SF36 was lower for the SOR-SMD group (p=0.03), mainly due to the difference in the Body pain sub-scale (p=0.04).

CONCLUSIONS

Results suggest that SOR-SMD is strongly associated with the sensory aspect of pain but weakly associated with the cognitive aspect. This indicates that SMD co-occurs with daily pain sensitivity, thus reducing QoL, but less with the cognitive-catastrophizing manifestation of pain perception.

Physiological Measures of Modulation in Individuals With Sensory Modulation Disorder (SMD)

Date Presented 4/17/2015

Endogenous analgesia mechanisms and central sensitization determine pain modulation processing. In this study, we aim to delineate neurophysiological mechanisms of endogenous analgesia in individuals with sensory modulation disorder (SMD). Efficient endogenous analgesia mechanisms are essential contributors to daily function.

Sensory Modulation, Psychological Distress, and Quality of Life in Young Adults in the General Population

Date Presented 4/17/2015

Psychological distress is a risk factor for mental health concerns. This study’s findings demonstrate reduced quality of life and elevated psychological distress within general population adults with sensory modulation disorder (SMD), hence validating the far-reaching claimed manifestations that SMD generates.

Psychophysical correlates in adults with sensory modulation disorder

PURPOSE

Individuals with sensory modulation disorder (SMD) demonstrate abnormal responses to naturally occurring stimuli in a manner that interferes with daily life activities. This study is the first study applying quantitative sensory testing to characterize the somatosensory sensitivity of adults with SMD.

METHOD

One hundred and fifty one adults (68 males and 83 females) were tested comparing 91 SMD to 60 SMD-free, control individuals. Group placement (SMD vs. SMD-free) was determined using the Sensory Responsiveness Questionnaire (SRQ). Sensory detection thresholds for skin warming, cooling, punctate dynamic tactile sensation, vibration and thermal pain thresholds for heat and cold stimuli were determined at several body sites. Pinprick pain and prickliness were also assessed, as well as the duration and intensity of the after-sensations of prickliness and pain evoked by the prickly stimuli.

RESULTS

Compared to control adults, individuals with SMD showed significantly higher pain intensity to prickle stimuli, marginally higher pain intensity to pinprick and hypoesthesia to punctate dynamic tactile sensation at one of two sites tested.

CONCLUSIONS

These results are in line with our previous study that investigated children with SMD using the same stimuli, and found similar results. We suggest a CNS involvement as the underlying mechanisms in SMD.

The Participation in Childhood Occupations Questionnaire (PICO-Q): a pilot study

There is a need, among practitioners and researchers, for a feasible, user-friendly assessment tool that evaluates overall participation and guides intervention. This paper describes the process of construction and development of the Participation in Childhood Occupations Questionnaire (PICO-Q) and the establishment of its primary psychometric properties. The 22-item instrument measures the level, enjoyment, and frequency of performance for children's participation in daily occupations in a variety of environments. The questionnaire was completed by the mothers of 41 children between the ages of 6 and 10 years (24 children with and 17 children without sensory modulation disorder). Cronbach's alpha varied from. 86 to. 89, indicating internal consistency of items. Test-retest reliability varied from. 69 to. 86, indicating that the instrument provides a stable measurement over time. The PICO-Q was found to differentiate between children with and without participation restrictions. The PICO-Q shows initial reliability and validity and has both research and clinical application potential.

Development and psychometric properties of the Sensory Responsiveness Questionnaire (SRQ)

PURPOSE

Individuals with Sensory Modulation Disorder (SMD) are characterized by an inability to normally grade the degree, intensity and nature of their responses to sensory input and are limited in their ability to fully participate in daily life activities, and attain optimal quality of life. Most existing diagnostic tools are intended for paediatric populations. A questionnaire that assesses the intensity of the affective-emotive responsiveness of adults to stimuli in all sensory modalities and the frequency of such responses for diagnosing adults with disorders in sensory modulation is necessary. This article describes the development and assessment of the psychometric properties of a novel instrument, the Sensory Responsiveness Questionnaire (SRQ), for this purpose (see Appendix).

METHOD

The SRQ evolved through three developmental phases (Pilot, Version-I, and the most recent Version-II). Each phase comprised several studies conducted to further refine the instrument and to examine its psychometric properties with adults with Sensory Modulation Disorder versus SMD-free individuals (n=39 for the pilot version, n=399 for Version-I, and n=48 for Version-II).

RESULTS

The scales of Version-II indicated high test-retest reliability, moderate criterion validity and strong significant construct validity.

CONCLUSION

There is strong indication that the SRQ can be used to diagnose adults with SMD.

Sensory modulation disorder: a risk factor for participation in daily life activities

Participation in childhood daily functional performance was examined in 78 children: 44 with sensory modulation disorder (SMD); (33 males, 11 females; mean age 7y 6mo [SD 1.20]) and 34 without SMD (18 males, 16 females; mean age 7y 8mo [SD 1.33]). Group classification was determined using two measures: the Short Sensory Profile (SSP) and the Full-form Sensory Profile. Parents completed a battery of caregiver questionnaires. Children with SMD scored significantly lower on all three participation scales than the control group. A high correlation was observed between level of activity performance of the Participation in Childhood Occupations Questionnaire (PICO-Q) and the SSP, and a moderate correlation was observed between the Enjoyment of Performance of the PICO-Q and the SSP. A low correlation was observed between Frequency of Performance of the PICO-Q and the SSP. Logistic regression indicated that all three participation scales (level of activity performance, level of enjoyment of the activity, and frequency of performance of the activity) are significantly associated with group classification, with odds ratios of 3.13, 2.05, and 1.73 respectively. These findings are the first, to our knowledge, to confirm claims of limited participation in daily activities among children with SMD. Our results have significant clinical implications and provide support for the need for practitioners and caregivers of children with SMD to facilitate participation.

Typical Children’s Responsivity Patterns of the Tactile and Vestibular Systems

OBJECTIVES. The purposes of this study were to investigate the responsivity patterns of typical 3- and 4year-old Israeli children to tactile or vestibular stimulation, or both, and to examine whether differences in these patterns exist between them with respect to age and gender.

METHOD. The study sample consisted of one hundred seventeen 3-year-old and one hundred forty-three 4year-old healthy Israeli children (N = 260). Mothers of these children completed a comprehensive tactile and vestibular responsivity questionnaire.

RESULTS. The subjects’ tactile and vestibular responsivity scores were neither hyperresponsive nor hypo-responsive. In addition, neither age nor gender was found to significantly differentiate between respective participant groups for hypo- or hyperresponsive behaviors.

CONCLUSION. Typical Israeli children can be characterized by moderate responsivities to tactile and vestibular stimulation. Responsivity to tactile and vestibular input was similar for 3- and 4-year-olds, across genders.
