“…In Leunkeu et al (2010), fatigue, as measured from the decline in median EMG frequency, was greater in individuals with CP than in the TD participants during submaximal isometric contractions of the quadriceps muscle. The increase in EMG amplitude was lower in the group with CP.…”

“…Study details and results are also summarized in Table 3. The participants in some studies (Stackhouse et al, 2005;Leunkeu et al, 2010;Doix et al, 2013;Eken et al, 2017Eken et al, , 2019 were children, whereas adolescents participated in some studies (Eken et al, 2014;Vitiello et al, 2016). The overall effect size was not calculated due to heterogeneity of the data in terms of participant characteristics, the muscles under investigation and the type of fatiguing task.…”

“…Although fatigue may greatly impact daily functioning and locomotion capacity in individuals with CP (Van der Slot et al, 2012), based on the relevant literature it is not easy to understand if fatigue in individuals with CP is higher (Jahnsen et al, 2003;Opheim et al, 2009;Leunkeu et al, 2010;Maanum et al, 2010;Nieuwenhuijsen et al, 2011;Van der Slot et al, 2012;Slaman et al, 2013;Eken et al, 2014Eken et al, , 2016Eken et al, , 2017Eken et al, , 2019Russchen et al, 2014; Vitiello et al, 2016;Lundh et al, 2018) lower, (Moreau et al, 2008(Moreau et al, , 2016Eken et al, 2013;Neyroud et al, 2017), or otherwise comparable (Stackhouse et al, 2005;Doix et al, 2013;Runciman et al, 2015Runciman et al, , 2016 with respect to fatigue in TD controls.…”

In this systematic review, we collected and analyzed literature works comparing self-reported fatigue and objectively-measured fatigue in individuals with cerebral palsy (CP) and in age-matched typically developing/typically developed (TD) controls (Healthy). The search was conducted on four electronic databases/platforms (PubMed, Web of Science, Cochrane Library, and Scopus) using the key words “cerebral palsy” combined with “fatig*,” where the asterisk was used as a wildcard. As a critical appraisal tool, the Joanna Briggs Institute Critical Appraisal Checklist for Quasi-Experimental Studies (2017) was used. A total of 22 studies passed the critical appraisal rating and were included in both narrative and quantitative analyses. The overall evidence quality of the findings was considered very good. Data of objectively-measured fatigue in performing maximal fatiguing tasks indicated lower fatigue levels in participants with CP, possibly due to their pathological inability to recruit highly fatigable muscle fibers. Highly trained individuals with CP and TD controls performing maximal fatiguing tasks seem to be an exception to this, as they exhibited similar levels of fatigue. In submaximal fatiguing tasks, including daily physical activities, either objectively-measured or self-reported fatigue was higher in participants with CP than in TD controls, indicating a lower ability for development of neurophysiological compensation for fatigue among participants with CP. Further studies on fatigue are needed to gain an insight into the multifold mechanisms of fatigue in individuals with CP. Understanding fatigue mechanisms could help in setting up strategies for effective intervention programs, with benefits in healthcare and improved quality of life of individuals with CP.Systematic Review Registration: [PROSPERO 2019], identifier [CRD42019143524].

“…Their subjects were classified as having either minor spasticity (Ashworth level 0-2) or major spasticity , with differences in plantar pressures between the two groups being influenced by their degree of spasticity. Factors limiting motor function in CP include spasticity (Elder et al, 2003;Ross et al, 2002;Engsberg et al, 2000), co-contraction (Femery et al, 2002), muscle weakness (Nsenga Leunkeu et al, 2010;Damiano et al, 2002), retractions and abnormalities (Van den linden et al, 2004). Femery et al (2002) found that in children with hemiplegia, the great toe did not participate in the push-off and significant differences of pressure were observed under the medial side of the heel compared to AB children.…”

BACKGROUND: Information on altered foot pressures during ambulation would clarify how far limb deformities modify walking patterns in cerebral palsy (CP), and whether such data can inform prognosis and guide rehabilitation. OBJECTIVE: To compare patterns of plantar pressures during walking between children with CP and their able-bodied (AB) peers. METHODS: Twenty-five children/adolescents (10 with hemiplegia, 5 with diplegia, and 10 AB, respective ages 13.0 ± 1.9, 13.0 ± 0.6 and 14.0 ± 0.7 years) walked a 12 m line at a self-selected speed. Spatio-temporal parameters and peak in-shoe plantar pressures were recorded for both feet, using the Parotec analysis system. RESULTS: Walking speeds (m·s −1 ) differed significantly between groups (0.65 ± 0.13, hemiplegia, 0.93 ± 0.22 diplegia and 1.26 ± 0.05 AB), with shorter stride lengths in CP. Contact time, double support time and step duration were also shorter in hemiplegia. Plantar pressures differed substantially and consistently between AB and CP, with increased medial heel pressures in hemiplegia, and reduced hallux and lateral heel pressures but increased lateral, medial mid-foot and first metatarsal pressures in diplegia. CONCLUSIONS: Substantial alterations in spatio-temporal parameters (greater in hemiplegia than in diplegia) and plantar pressure distribution reflect attempts to compensate for poor stability of posture in CP. Further study of these adaptive changes holds clinical promise in providing data relevant to the design of orthotics, determinations of prognosis and the planning of neurorehabilitation.

“…The conduction velocity is the main index, it decreases more or less rapidly depending on the level of contraction and is generally measured during isometric constant force contraction. The measurement of muscle fatigue in CP using sEMG reveals differences relative to the age-matched controls (78,79).…”

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

et al. 2020

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.
