Sensory symptoms across the lifespan in people with cerebral palsy

Abstract

AIM: To estimate prevalence of sensory symptoms in people with cerebral palsy (CP) across the lifespan. METHOD: In this cross-sectional study, the self-reported Sensory Processing Scale Inventory (SPS-I) was administered via REDCap between 2/1/22 and 8/15/22 to people with CP or their caregivers enrolled in the online MyCP Community Registry. We determined the association between SPS-I scores and age (Pearson correlation) and functional status as assessed using five validated functional classification systems for CP (ANOVA). We hypothesized that sensory symptoms would differ between younger and older individuals with CP. RESULTS: Of 155 responses (28% response rate, age 1-76 years, 34% male), 97% reported at least one bothersome sensory symptom. Total sensory symptoms decreased with age (R2=0.12, p<0.0001), driven by decreases in hyposensitivity symptoms (R2=0.32, p<0.0001), primarily tactile hyposensitivity (R2=0.29, p<0.0001). Sensory symptoms increased with greater functional impairment across all functional domains (ANOVA, p<0.0001). However, the age-specific decrease in hypo-sensitivities was most pronounced in people with the greatest gross motor functional impairment (R2=0.70, p=0.0004). INTERPRETATION: Our findings suggest that hypo-sensitivity, primarily tactile sensitivity, decreases with age in people with CP. Future work should assess whether decreased hyposensitivity contributes to other age-related changes in CP like increased pain.

Sensory experiences questionnaire unravels differences in sensory profiles between MECP2‐related disorders

“…Understanding what these differences mean clinically will require further work evaluating subdomains of touch sensitivity such as stereognosis, roughness, hardness, and heaviness (Liang et al, 2023). Interestingly, hyposensitivity in general appears related to pain perception with hyposensitivity corresponding with a known age dependent change in pain tolerance in, for example, cerebral palsy (Lyons-Warren et al, 2024). Further, stereotypies are associated with both syndromes, although the semiology differs between the two.…”

A Case Study on the Fundamentals of Sensory Problems in Cerebral Palsy

“…Activity-based neurorehabilitation treatment can enhance voluntary sensory-motor function when non-invasive spinal neuromodulation is used as an intervention The majority of the earlier studies for connecting the treatment were done for motor problems. However, thorough sensory examination has been neglected in earlier studies (16) .…”
