Adults with spastic diplegic cerebral palsy living in a low-to-middle income Country: A six-year follow-up study on pain, functional mobility, activity and participation

Exploring the unmet needs of adults with cerebral palsy living in urban South Africa

PURPOSE

The investigators aimed to understand the unmet needs of adults with cerebral palsy (CP) living in urban South Africa and to ascertain similarities or differences to typically developing (TD) adults in the same community.

MATERIALS AND METHODS

Participants were interviewed with an adapted version of the Southampton Needs Assessment Questionnaire (SNAQ). Non-parametric statistical analysis was utilised for quantitative data and qualitative data were analysed using free coding to identify themes.

RESULTS

Thirty adults with CP (median age 34.8 years; GMFCS levels I/II/III/IV/V: n = 6/6/5/7/6; socio-economic status (SES) low/average/high: n = 8/17/5) were matched for gender, age, and SES. Adults with CP reported a higher unemployment rate and lower level of satisfaction with access to health services than TD peers. Core themes identified by the participants with CP that made community participation more difficult were physical capacity, poor access to accommodation, transport and health services, lack of socialising opportunities, poor universal design, and lack of financial independence.

CONCLUSIONS

Adults with CP reported experiencing many challenges in their communities. Improved access to health care services and transport, and the universal design of housing and community buildings to accommodate individuals with a disability should be made a priority.Implications for rehabilitationAdults with cerebral palsy (CP) reported that their disability had an impact on their social life, home life, and work life.Accessibility issues have been identified as a major factor affecting adults with CP in a variety of areas, including access to and use of health services, housing, transportation, and community buildings.Adults with CP reported the need for support during the transition to adulthood, especially with developing life skills that will promote living independently in the community as adults with disabilities.

Automated facial recognition system using deep learning for pain assessment in adults with cerebral palsy

Objective

Assessing pain in individuals with neurological conditions like cerebral palsy is challenging due to limited self-reporting and expression abilities. Current methods lack sensitivity and specificity, underlining the need for a reliable evaluation protocol. An automated facial recognition system could revolutionize pain assessment for such patients.The research focuses on two primary goals: developing a dataset of facial pain expressions for individuals with cerebral palsy and creating a deep learning-based automated system for pain assessment tailored to this group.

Methods

The study trained ten neural networks using three pain image databases and a newly curated CP-PAIN Dataset of 109 images from cerebral palsy patients, classified by experts using the Facial Action Coding System.

Results

The InceptionV3 model demonstrated promising results, achieving 62.67% accuracy and a 61.12% F1 score on the CP-PAIN dataset. Explainable AI techniques confirmed the consistency of crucial features for pain identification across models.

Conclusion

The study underscores the potential of deep learning in developing reliable pain detection systems using facial recognition for individuals with communication impairments due to neurological conditions. A more extensive and diverse dataset could further enhance the models' sensitivity to subtle pain expressions in cerebral palsy patients and possibly extend to other complex neurological disorders. This research marks a significant step toward more empathetic and accurate pain management for vulnerable populations.

Reduced brainstem volume is associated with mobility impairments in youth with cerebral palsy

BACKGROUND

Persons with cerebral palsy (CP) have impaired mobility that has been attributed to changes in structure and function within the nervous system. The brainstem is a region that plays a critical role in mobility by connecting the cortex and cerebellum to the spinal cord, yet this region has been largely unstudied in persons with CP.

RESEARCH QUESTION

We used high-resolution structural MRI and biomechanical analyses to examine whether the volume of the whole brainstem and its constituent elements are altered in CP and if these alterations relate to the mobility impairments within this population.

METHODS

A cohort study was conducted to assess the volume of the whole brainstem, pons, midbrain, medulla, and superior cerebellar peduncle in a cohort of persons with CP (N = 26; Age = 16.3 ± 1.0 years; GMFCS levels I-IV, Females = 12) and a cohort of neurotypical (NT) controls (N = 38; Age = 14.3 ± 0.4 years, Females = 14) using structural MR imaging of the brainstem. Outside the scanner, a digital mat was used to quantify the spatiotemporal gait biomechanics of these individuals.

RESULTS

We found a significant decrease in volume of the total brainstem, midbrain, and pons in persons with CP in comparison to the NT controls. Furthermore, we found that the altered volumes were related to reduced gait velocity and step length.

SIGNIFICANCE

The structural changes in the brainstems of persons with CP may contribute to the mobility impairments that are ubiquitous within this population.

Evaluation of daily and social participation of children with Cerebral Palsy across different age groups with a focus on the 'F'-words: Function, family, fitness, fun, friends and future

BACKGROUND

The impact of disability differs across cultures. This study aimed to determine the predictors of participation in children with cerebral palsy (CP) in Turkey, based on the six F-words.

METHODS

Cross-sectional study exploring participation profiles of 450 children with CP, aged between 2 and 18 years. Pediatric Evaluation of Disability Inventory (PEDI) evaluated functional skills, and Assessment of Life Habits (LIFE-H) version 3.0 assessed daily and social participation. Hierarchical linear regression models were done to determine the predictors of participation in daily activities (PDA) and social roles (PSR) in three age groups (2-4, 5-13 and 14-18 years) based on the 6 F-words (mobility of PEDI for 'fitness'; four classification systems and self-care of PEDI for 'functioning'; social functions of PEDI for 'friends'; demographic information by parents for 'family'; the recreation of LIFE-H for 'fun'; and different stages of development for 'future').

RESULTS

The most important predictors for total PDA by age group were: self-care (p = 0.012) of PEDI in 2-4 y; self-care (p = 0.001) and mobility (p = 0.005) of PEDI in 5-13 y; GMFCS (p = 0.006) and mobility (p = 0.002) of PEDI in 14-18 y. Significant predictors for PSR differed by age group: self-care (p = 0.001) of PEDI in 2-4 y; self-care (p = 0.023) and mobility (p = 0.006) of PEDI in 5-13 y; and GMFCS (p = 0.004) and MACS (p = 0.003) in 14-18 y.

CONCLUSIONS

Six F-words of function and fitness focussed on self-care in younger children with an increasing emphasis on mobility and ability levels according to age. Therefore, rehabilitation for different aspects of the functional levels is needed to improve participation in life across the six F-words framework; plus take into consideration context, age-differences, family's expectations, life requirements, environmental needs, and cultural differences.

Reduced Brainstem Volume is Associated with Mobility Impairments in Youth with Cerebral Palsy

Persons with cerebral palsy (CP) have impaired mobility that has been attributed to changes in structure and function within the nervous system. The brainstem is a region that plays a critical role in locomotion by connecting the cortex and cerebellum to the spinal cord, yet this region has been largely unstudied in persons with CP. The objective of this investigation was to use high-resolution structural MRI and biomechanical analyses to examine whether the volume of the whole brainstem and its constituent elements are altered in CP, and if these alterations relate to the mobility impairments within this population. We assessed the volume of the pons, midbrain, medulla, and superior cerebellar peduncle (SCP) in a cohort of persons with CP (N = 26; Age = 16.3 ± 1.0 yrs; GMFCS levels I-IV, Females = 12) and a cohort of neurotypical (NT) controls (N = 38; Age = 14.3 ± 0.4 yrs, Females = 14) using structural MR imaging of the brainstem. Outside the scanner, a digital mat was used to quantify the spatiotemporal gait biomechanics of these individuals. Our MRI results revealed that there was a significant decrease in volume of the total brainstem, midbrain, and pons in persons with CP in comparison to the NT controls. Furthermore, we found that the altered volumes were related to reduced gait velocity and step length. These results suggest that there are structural changes in the brainstems of persons with CP that may contribute to the mobility impairments that are ubiquitous within this population.

Comparison of Gross Motor Outcomes Between Children With Cerebral Palsy From Appalachian and Non-Appalachian Counties

PURPOSE

This study evaluated gross motor outcomes between children with cerebral palsy from non-Appalachian and Appalachian counties in the United States.

METHODS

For this retrospective, matched-case controlled study, data were sourced from electronic medical record and compared between groups. Groups were matched by age and Gross Motor Function Classification System (GMFCS) level.

RESULTS

Children from Appalachian counties had significantly higher Gross Motor Function Measure, 66 (GMFM-66) scores and had a cerebral palsy diagnosis reported in the electronic medical record significantly later compared with children from non-Appalachian counties, controlling for age and GMFCS level.

CONCLUSION

Although it has been documented that families and children from Appalachian counties have poorer overall health outcomes, motor development may not be affected. Our study found that children with cerebral palsy from Appalachian counties scored significantly higher on the GMFM-66 across GMFCS levels.

Altered spontaneous cortical activity predicts pain perception in individuals with cerebral palsy

Cerebral palsy is the most common paediatric neurological disorder and results in extensive impairment to the sensorimotor system. However, these individuals also experience increased pain perception, resulting in decreased quality of life. In the present study, we utilized magnetoencephalographic brain imaging to examine whether alterations in spontaneous neural activity predict the level of pain experienced in a cohort of 38 individuals with spastic diplegic cerebral palsy and 67 neurotypical controls. Participants completed 5 min of an eyes closed resting-state paradigm while undergoing a magnetoencephalography recording. The magnetoencephalographic data were then source imaged, and the power within the delta (2–4 Hz), theta (5–7 Hz), alpha (8–12 Hz), beta (15–29 Hz), low gamma (30–59 Hz) and high gamma (60–90 Hz) frequency bands were computed. The resulting power spectral density maps were analysed vertex-wise to identify differences in spontaneous activity between groups. Our findings indicated that spontaneous cortical activity was altered in the participants with cerebral palsy in the delta, alpha, beta, low gamma and high gamma bands across the occipital, frontal and secondary somatosensory cortical areas (all p_FWE < 0.05). Furthermore, we also found that the altered beta band spontaneous activity in the secondary somatosensory cortices predicted heightened pain perception in the individuals with cerebral palsy (P = 0.039). Overall, these results demonstrate that spontaneous cortical activity within individuals with cerebral palsy is altered in comparison to their neurotypical peers and may predict increased pain perception in this patient population. Potentially, changes in spontaneous resting-state activity may be utilized to measure the effectiveness of current treatment approaches that are directed at reducing the pain experienced by individuals with cerebral palsy.
