Individual endogenous pain modulation profiles within a multidimensional context of people with cervicogenic headache – a retrospective exploratory study

Background: One in four individuals with cervicogenic headache (CeH) are unresponsive to therapy. Such therapy involves predominantly biomedical interventions targeting the upper-cervical spine. A recurring theme within musculoskeletal practice is the multidimensional nature and substantial heterogeneity of the condition. Such heterogeneity might be a reason for failure of a biomedical approach. Therefore, future studies investigating efficacy of managing CeH should ideally be based on identification, and better understanding of the heterogeneity of this population based on a comprehensive evaluation of clinically relevant contributing factors. Objectives: The objective was to map profiles of individuals with CeH based on pain modulation within a multidimensional context. Design: Pain Modulation Profiles (PMPs) of 18 adults (29–51 years) with CeH were mapped retrospectively. Method: The PMPs consisted of a Pain-Profile (bilateral suboccipital, erector spinae, anterior tibialis pressure pain thresholds), a Psycho-Social-Lifestyle-Profile (Depression, Anxiety, Stress Scale, Headache Impact test, Pittsburgh Sleep Quality Index), or a combination of both. Individual results were compared to normative data. Two Pain-Profiles were defined: normal or altered. Psycho-Social-Lifestyle-Profiles were categorized based on the number of altered psycho-social-lifestyle factors (range 0–5). Results: Mapping PMPs in individuals with CeH resulted in 50% presenting with a dominant altered Pain-Profile, 16.7% with a dominant altered Psycho-Social-Lifestyle-Profile, and 5.6% with dominant alterations in both Pain-Profile and Psycho-Social-Lifestyle-Profile. Conclusion: Our results indicate heterogeneity of PMPs within the CeH population. Replication of these results is needed through dynamic assessment of the Pain-Profile before evaluating if these profiles can help patient-stratification

Cross-sectional experimental assessment of pain modulation as part of multidimensional profiling of people with cervicogenic headache: protocol for a feasibility study

Background: An endogenous pain modulation profile, reflecting antinociceptive and pronociceptive mechanisms, may help to direct management by targeting the involved pain mechanism. For individuals with cervicogenic headache (CeH), the characteristics of such profiles were never investigated. However, the individual nature of experiencing pain demands profiling within a multidimensional framework including psychosocial lifestyle characteristics. The objective of the current protocol is to assess the pain modulation profile, which includes psychosocial lifestyle characteristics among people with CeH. Methods and analysis: A protocol is described to map pain modulation profiles in people with CeH. A cross-sectional non-randomised experimental design will be used to assess feasibility of mapping these profiles. The pain modulation profile is composed based on results on the Depression, Anxiety, Stress Scale, Pittsburgh Sleep Quality Index, Headache Impact Test and on responses to temporal summation of pain (pinprick), conditioned pain modulation and widespread hyperalgesia (mechanical pressure pain threshold and cuff algometry). Primary analyses will report results relating to outcomes on feasibility. Secondary analyses will involve an analysis of proportions (%) of the different psychosocial lifestyle profiles and pain profiles. Ethics and dissemination: Ethical approval was granted by the Ethics Committee Research UZ/KU Leuven (Registration number B3222024001434) on 30 May 2024. Results will be published in peer-reviewed journals, at scientific conferences and, through press releases. Protocol V.3. protocol date: 3 June 2024

Effects of home-based play-assisted stimulation on developmental performances of children living in extreme poverty : a randomized single-blind controlled trial

Background: Children living with foster families in a resource-limited setting such as Ethiopia are at risk of developmental problems. It is not yet clear whether intensive home-based developmental stimulation assisted by play can reduce these problems. The main objective of this study was to examine the effects of play-assisted intervention integrated into basic services on the developmental performance of children living with foster families in extreme poverty. Methods: A randomized single-blind (investigator) controlled trial design was used. The study was conducted in Jimma, South West Ethiopia. Using computer-generated codes, eligible children of 3-59 months in age were randomly allocated to intervention (n = 39) and control (n = 39) groups at a 1:1 ratio. Children in the intervention group received home-based play-assisted stimulation in addition to the basic services provided to children in both groups. The intervention consisted of an hour of play stimulation conducted during a weekly home visit over the course of six months. Personal-social, language, fine and gross motor outcomes were assessed using Denver II-Jimma, and social-emotional outcome was obtained using an adapted Ages and Stages Questionnaire: Social-Emotional (ASQ: SE). Information about sociodemographic characteristics was collected using a structured questionnaire. Anthropometric methods were used to determine nutritional status. The effects of the intervention on the abovementioned outcomes over the study period and group differences in change over time were examined using Generalized Estimating Equations (GEE). Results: Statistically significant intervention effects were found for language (P = 0.0014), personal-social (P = 0.0087) and social-emotional (P < 0.0001) performances. At the midline of the study, language (effect size = 0.34) and social-emotional (effect size = - 0.603) benefits from the play-assisted stimulation had already been observed for the children in the intervention group. For language, the intervention effect depended on the child's sex (P = 0.0100) and for personal-social performance, on family income (P = 0.0300). Conclusions: Intensive home-based play-assisted stimulation reduced the developmental problems of children in foster families in the context of extreme poverty. Longer follow-up may reveal further improvements in the developmental performance of the children

The relationship of undernutrition/psychosocial factors and developmental outcomes of children in extreme poverty in Ethiopia

Background: Extreme poverty is severe deprivation of basic needs and services. Children living in extreme poverty may lack adequate parental care and face increased developmental and health risks. However, there is a paucity of literature on the combined influences of undernutrition and psychosocial factors ( such as limited play materials, playground, playtime, interactions of children with their peers and mother-child interaction) on children's developmental outcomes. The main objective of this study was, therefore, to ascertain the association of developmental outcomes and psychosocial factors after controlling nutritional indices. Methods: A community-based cross-sectional study design was used to compare the developmental outcomes of extremely poor children (N = 819: 420 girls and 399 boys) younger than 5 years versus age-matched reference children (N = 819: 414 girls and 405 boys) in South-West Ethiopia. Using Denver II-Jimma, development in personalsocial, language, fine and gross motor skills were assessed, and social-emotional skills were evaluated using the Ages and Stages Questionnaires: Social-Emotional (ASQ: SE). Nutritional status was derived from the anthropometric method. Independent samples t-test was used to detect mean differences in developmental outcomes between extremely poor and reference children. Multiple linear regression analysis was employed to identify nutritional and psychosocial factors associated with the developmental scores of children in extreme poverty. Results: Children in extreme poverty performed worse in all the developmental domains than the reference children. Among the 819 extremely poor children, 325 (39.7%) were stunted, 135 (16.5%) were underweight and 27 (3.3%) were wasted. The results also disclosed that stunting and underweightness were negatively associated with all the developmental skills. After taking into account the effects of stunting and being underweight on the developmental scores, it was observed that limited play activities, limited child-to-child interactions and motherchild relationships were negatively related mainly to gross motor and language performances of children in extreme poverty. Conclusion: Undernutrition and psychosocial factors were negatively related to the developmental outcomes, independently, of children living in extreme poverty. Intervention, for these children, should integrate home-based play-assisted developmental stimulation and nutritional rehabilitation

Habitual Cervical Posture in Women With Episodic Cervicogenic Headache Versus Asymptomatic Controls

OBJECTIVE: The purpose of this study was to compare the habitual cervical posture between a headache group and control group by using a (1) relative approach (ratio habitual cervical posture to maximal active cervical flexion) and a (2) longitudinal approach compared with a conventional approach. METHODS: Case-controlled longitudinal (pre-post) comparison of the habitual cervical posture referred to the maximal active cervical flexion between 17 women with secondary episodic cervicogenic headache (23.2 ± 1.8 years) and 17 matched controls (23.6 ± 2.2 years) before and after a desk task. Habitual cervical posture and maximal active cervical flexion were measured with a cervical range of motion device (degrees) before and after a desk task (manually completing the Headache Impact Test-6, 36-Item Short Form Health Survey, and general informative questionnaire during 20 minutes). RESULTS: During the pretest, the headache group differed significantly (P < .05) from the control group by showing a (1) smaller maximal active cervical flexion, and (2) positive correlation (ρ 0.56) between maximal active cervical flexion and the habitual cervical posture. After the desk task, the headache group vs the control group showed a significant (P < .05) (1) habitual cervical posture toward flexion, (2) negative correlation (ρ -0.64) between more cervical flexion at the pretest and a more cervical extension during the post-test, and (3) positive association (P < .001) between a larger habitual cervical posture referred to the maximal active cervical flexion and a higher headache intensity. CONCLUSION: Longitudinal measurements of the ratio habitual cervical posture to the maximal active cervical flexion seem to be more sensitive to capture small cervical postural differences between patients with secondary cervicogenic headache and a control group compared with absolute, cross-sectional measurements.status: publishe

Preclinical Signs of a Temporomandibular Disorder in Female Patients With Episodic Cervicogenic Headache Versus Asymptomatic Controls: A Cross-Sectional Study

BACKGROUND: The International Classification of Headache Disorders, 3rd Edition, accepted "headache attributed to temporomandibular disorders" as a valid headache. The neurophysiologic interplay between cervical structures and the temporomandibular joint, however, might also suggest that a temporomandibular disorder could develop in patients with cervicogenic headache. OBJECTIVE: To compare the presence of preclinical temporomandibular signs between female patients with episodic cervicogenic headache and a control group. DESIGN: Case-controlled cross-sectional design. SETTING: Institutional setting: Hasselt University. PARTICIPANTS: Twenty-two women (mean age ± SD: 20.7 ± 2.5 years) with episodic cervicogenic headache, without temporomandibular signs and 22 matched (gender, age, level of education, occupation) asymptomatic controls (21 ± 2.3 years). METHODS: (Un)assisted temporomandibular range of motion, pressure pain thresholds, painful palpations were examined and the level of perceived stress was measured. MAIN OUTCOME MEASUREMENTS: Temporomandibular range of motion (mm), pressure pain thresholds (kPa/cm²), painful palpations (yes/no), and level of perceived stress (Perceived Stress Scale). RESULTS: Maximal mouth-opening was significantly smaller in the headache group (P <.05; effect size [ES] -0.45). Palpation of the masseter resulted in significantly more positive pain responses in the headache group at the left (P = .009; ES ∞) and right (P = .002;ES 17.5) origin, left (P = .004; ES 14.54) and right (P = .03; ES 5.71) body and left (P < .001; ES 12) insertion. Significantly lower pressure pain thresholds on the left and right anterior (P = .03; ES -0.33 resp. P = .02; ES -0.35), central (P = .003; ES 1.02 resp. P = .02; ES 0.79) and right posterior (P = .03; ES 0.62) temporalis and right tibialis anterior (P = .03; ES -0.33) were measured in the headache group. The level of perceived stress was significantly higher (P = .02) in the headache group. CONCLUSIONS: Patients with episodic cervicogenic headache present with signs of a preclinical temporomandibular disorder and sensitization. The smaller range of motion, lower pressure pain thresholds, and higher levels of stress accentuate the multidimensionality of the problem. LEVEL OF EVIDENCE: IV.status: publishe

Inter-individual variability in mechanical pain sensation in patients with cervicogenic headache: an explorative study

Abstract Currently, evidence for effective physiotherapy interventions in patients with cervicogenic headache (CeH) is inconsistent. Although inter-individual variability in pain response is predictive for successful physiotherapy interventions, it was never explored in patients with CeH. Therefore the objective of the current study was to explore inter-individual variability in mechanical pain sensation, and its association with biopsychosocial-lifestyle (BPSL) characteristics in patients with CeH. A cross-sectional explorative analysis of inter-individual variability in mechanical pain sensation in 18 participants with CeH (29–51 years) was conducted. Inter-individual variability in mechanical pain sensation (standard deviations (SDs), F-statistics, Measurement System Analysis) was deducted from bilateral pressure pain thresholds of the suboccipitals, erector spine, tibialis anterior. BPSL-characteristics depression, anxiety, stress (Depression Anxiety Stress Scale-21), quality of life (Headache Impact Test-6), sleep-quality (Pittsburgh Sleep Quality Index), and sedentary time (hours/week) were questioned. Inter-individual variability in mechanical pain sensation explained 69.2% (suboccipital left), 86.8% (suboccipital right), 94.6% (erector spine left), 93.2% (erector spine right), 91.7% (tibialis anterior left), and 82% (tibialis anterior right) of the total variability in patients with CeH. The significant p-values and large F-statistic values indicate inter-individual differences in SDs. Significant associations between (1) lower quality of life and lower SDs of the suboccipital left PPT (p .005), and (2) longer sedentary time and higher SDs of the suboccipital left PPT (p .001) were observed. Results from our explorative study could suggest inter-individual variability in mechanical pain sensation at the left suboccipitals which associates with quality of life and sedentary time. These novel findings should be considered when phenotyping patients and ‘individually’ match interventions

What is the status quo of patient-centred physiotherapy management of people with headache within a biopsychosocial model?– A Narrative Review

Patient-centered care is gaining popularity within the rehabilitation of pain conditions. Integrating such care within a biopsychosocial model enables to address all facets of thean individual pain experience, and to manage the individual as in opposite to the disorder. An individual approach might be beneficial in pain conditions with inconclusive or ignorable therapy effects such as in people with headache. Heterogeneity within this population, and within the applied physiotherapy modalities might contribute to the inconclusive results of physiotherapeutic management. A third contributing factor might be the mainly biomedical focus of such management. The current narrative review attempts to map evidence to support the biopsychosocial model within patient-centered physiotherapeutic management of headache. Main question Evidence to support the BPS model within a personalized physiotherapeutic management of headache? Databases and search query A literature search is conducted in the PubMed, EMBASE, Web of Science, and Scopus databases. The search query comprised controlled terminology and free text words relating to “Headache”, “Personalized”, “Tailored”, “Patient-centered”, “Targeted”, “Individualized”, “Biopsychosocial”, “Bio-behavioural”, “holistic”, and “Physiotherapy”. No date restrictions are applied. Studies written in English, Dutch, or French were considered during the screening phase

Developmental performance of hospitalized severely acutely malnourished under-six children in low- income setting

Abstract Background Retrospective studies show that severe acute malnutrition (SAM) affects child development. However, to what extent SAM affects children of different ages at its acute stage is not well documented. This study was aimed at comparing the developmental performance of severely acutely malnourished children under six with that of age and gender-matched non-malnourished healthy children. Methods The developmental performances of 310 children with SAM (male = 155, female = 155); mean age = 30.7 mo; SD = 15.2 mo) admitted to the nutritional rehabilitation unit (NRU) at Jimma University’s Hospital was compared with that of 310 age and gender-matched, non-malnourished healthy children (male = 155, female = 155; mean age = 29.6 mo; SD = 15.4 mo) living in Jimma Town in Ethiopia. Two culturally adapted tools were used: (1) the Denver II-Jimma, to assess the children’s performance on personal social (PS), fine motor (FM) language (LA), gross motor (GM) skills, and (2) the Ages and Stages Questionnaires: Social-Emotional (ASQ:SE), to assess social-emotional (SE) skills. Multivariable Poisson regression analysis was conducted to compare the developmental performance scores of SAM and non-malnourished children. Results For one-year-old children, SAM delays their developmental performance on GM, FM, PS and LA by 300%, 200%, 140% and 71.4% respectively. For three-years-old children, SAM delays their developmental performance on GM by 80%, on FM and LA by 50% each, and on PS by 28.6%. Of the skills assessed on Denver II-Jimma, GM is the most, and PS is the least affected. Younger SAM children are more affected than older ones on all the domains of development. The delay in FM, GM, LA and PS generally decreases with an increase in age. Social-emotional behavior problems seem to be most pronounced in the very young and older age ranges. Conclusions SAM has a differential age effect on the different dimensions of development in children under 6 years of age

Comparative analysis of head-tilt and forward head position during laptop use between females with postural induced headache and healthy controls

OBJECTIVES: To compare 1) maximum manually induced head-protraction, head-tilt and forward head position and 2) the evolution of head-tilt and forward head position during a laptop-task between a headache- and control-group. METHODS: Angles for maximum head-protraction, head-tilt and forward head position of 12 female students with postural induced headache and 12 female healthy controls were calculated at baseline and while performing a laptop-task. RESULTS: The headache-group demonstrated an increased passive head-protraction of 22.30% compared to the control-group. The ratio of forward head position during habitual sitting to the maximum head-protraction differed significantly (p = 0.046) between headache-group (1.4 ± 0.4) and the control-group (1.1 ± 0.2). The headache-group showed a biphasic forward head position and head-tilt profile. These profiles differed significantly (p < 0.05) between groups and were negatively correlated (rE = -0.927). CONCLUSION: The headache-group showed a larger passive head-protraction with a habitual forward head-position further located from the end-range. During the laptop-task forward head position and head-tilt behaved biphasically with a more static forward head position and a more dynamic head-tilt.publisher: Elsevier articletitle: Comparative analysis of head-tilt and forward head position during laptop use between females with postural induced headache and healthy controls journaltitle: Journal of Bodywork and Movement Therapies articlelink: http://dx.doi.org/10.1016/j.jbmt.2015.11.015 content_type: article copyright: © 2015 Elsevier Ltd.
