Clinical Relevance of State-of-the-Art Analysis of Surface Electromyography in Cerebral Palsy

Surface electromyography (sEMG) can be used to assess the integrity of the neuromuscular system and its impairment in neurological disorders. Here we will consider several issues related to the current clinical applications, difficulties and limited usage of sEMG for the assessment and rehabilitation of children with cerebral palsy. The uniqueness of this methodology is that it can determine hyperactivity or inactivity of selected muscles, which cannot be assessed by other methods. In addition, it can assist for intervention or muscle/tendon surgery acts, and it can evaluate integrated functioning of the nervous system based on multi-muscle sEMG recordings and assess motor pool activation. The latter aspect is especially important for understanding impairments of the mechanisms of neural controllers rather than malfunction of individual muscles. Although sEMG study is an important tool in both clinical research and neurorehabilitation, the results of a survey on the clinical relevance of sEMG in a typical department of pediatric rehabilitation highlighted its limited clinical usage. We believe that this is due to limited knowledge of the sEMG and its neuromuscular underpinnings by many physiotherapists, as a result of lack of emphasis on this important methodology in the courses taught in physical therapy schools. The lack of reference databases or benchmarking software for sEMG analysis may also contribute to the limited clinical usage. Despite the existence of educational and technical barriers to a widespread use of, sEMG does provide important tools for planning and assessment of rehabilitation treatments for children with cerebral palsy

Telerehabilitation during Covid-19 lockdown and gross motor function in cerebral palsy: an observational study

Background: COVID-19 (Coronavirus Disease-2019) refers to a mainly respiratory disease, caused by a new SARS-CoV-2 virus predominantly transmitted through direct or indirect contact with mucous membranes of eyes, mouth, or nose. The main control measures are physical distancing, use of specific protective devices, hand hygiene and disinfection of environments and tools. During this health emergency, telemedicine and telerehabilitation guaranteed patients to receive continuity of care through a virtual support while maintaining physical distance. Aim: The aim of this study is to evaluate the effects of telerehabilitation on gross motor skills in children with Cerebral Palsy (CP) during Covid-19 lockdown. Design: observational study. Setting: Pediatric Outpatient Neurorehabilitation Service. Population: 53 children with Cerebral Palsy aged between 6 months and 12 years classified according to the Gross Motor Function Classification System (GMFCS). Methods: variation on the Gross Motor Function Measure-66 (GMFM-66) score calculated before and after the telerehabilitation period was analyzed. Results: after telerehabilitation there was a statistically significant increase in the median value of GMFM scores both on the total sample (from 54.82% to 63.18%, p-value 0.000005) and in the subgroups. Specifically, in children classified as level I and II at the GMFCS, this value increased more after the telerehabilitation period. Only the GMFCS level V group did not show statistically significant changes and only in two cases a decrease in the GMFM score after the telerehabilitation phase occurred. Conclusions: telerehabilitation can be considered an efficient tool that can temporarily replace the in person therapy. It can allow the patient or caregiver to acquire skills in performing home exercises and to integrate and implement activity carried out at the rehabilitation center. Clinical rehabilitation impact: this study shows a positive effect of telerehabilitation on gross motor function in children with cerebral palsy

Assistive products and childhood neurodisability: a retrospective study on factors associated with aids/orthoses prescription

Children affected by pathologies causing neurodisability go through motor, cognitive, sensory and other limitations. The selection of assistive products can influence their level of independence and quality of life

Comparison of the forward and sideways locomotor patterns in children with Cerebral Palsy

Abstract Switching locomotion direction is a common task in daily life, and it has been studied extensively in healthy people. Little is known, however, about the locomotor adjustments involved in changing locomotion direction from forward (FW) to sideways (SW) in children with cerebral palsy (CP). The importance of testing the ability of children with CP in this task lies in the assessment of flexible, adaptable adjustments of locomotion as a function of the environmental context. On the one hand, the ability of a child to cope with novel task requirements may provide prognostic cues as to the chances of modifying the gait adaptively. On the other hand, challenging the child with the novel task may represent a useful rehabilitation tool to improve the locomotor performance. SW is an asymmetrical locomotor task and requires a differential control of right and left limb muscles. Here, we report the results of a cross-sectional study comparing FW and SW in 27 children with CP (17 diplegic, 10 hemiplegic, 2–10 years) and 18 age-matched typically developing (TD) children. We analyzed gait kinematics, joint moments, EMG activity of 12 pairs of bilateral muscles, and muscle modules evaluated by factorization of EMG signals. Task performance in several children with CP differed drastically from that of TD children. Only 2/3 of children with CP met the primary outcome, i.e. they succeeded to step sideways, and they often demonstrated attempts to step forward. They tended to rotate their trunk FW, cross one leg over the other, flex the knee and hip. Moreover, in contrast to TD children, children with CP often exhibited similar motor modules for FW and SW. Overall, the results reflect developmental deficits in the control of gait, bilateral coordination and adjustment of basic motor modules in children with CP. We suggest that the sideways (along with the backward) style of locomotion represents a novel rehabilitation protocol that challenges the child to cope with novel contextual requirements

Robotic-Assisted Hand Therapy with Gloreha Sinfonia for the Improvement of Hand Function after Pediatric Stroke: A Case Report

Background: Stroke in childhood presents a serious rehabilitation challenge since it leads to physical, cognitive and psychosocial disability. The objective of our study was to describe the effectiveness of robot-mediated therapy (RMT) with Gloreha Sinfonia in addition to a conventional treatment in the recovery of the sensory-motor capabilities of the paretic hand and the quality of life in a ten-year-old child after a stroke. Methods: The girl was enrolled to undergo 10 sessions of RMT with Gloreha Sinfonia. She was evaluated with functional scales and with upper limb kinematic analysis at pre-treatment (T0) and at the end of treatment (T1). Outcome measures were Fugl-Meyer Assessment-Upper Extremity (FMA-UE), Visual Analogic Scale (VAS) and Activities and Participation of Daily Life (ADL). In addition, a Force Assessment System based on Virtual Reality games was used to assess the force control and modulation capability at T0 and T1. Results: At the end of treatment, the patient improved in functional scales and in quality of life for greater involvement in some activity of daily living. Force control and modulation capability significantly increased after the treatment. Conclusions: This clinical case highlights possible positive effects of a combined (conventional plus robotic) rehabilitation treatment for the upper limb in pediatric stroke outcomes from both a sensorimotor and functional point of view, also improving the motivational and affective aspects of the patient and of family members. Further studies are needed to validate these results and to identify the most appropriate modalities and doses
