“…Muscle and tendon lengths were assessed using 3D freehand ultrasound (3DfUS); combining conventional B-mode 2D ultrasound (Telemed EchoBlaster128, Vilnius, Lithuania) with 3D motion analysis (Optitrack NaturalPoint, USA), as previously described (22). The US acquisition parameters were kept constant between the different acquisitions (frequency, 10 MHz; depth, 5 cm; focus, 1.8-2.8 cm; gain, 46%; dynamic range, 44 dB and unaltered time-gain compensation) (23). This method has proven to be valid with a strong inter acquirer reliability in both healthy and pathological muscles (23,24).…”

Botulinum NeuroToxin-A (BoNT-A) injections to the medial gastrocnemius (MG) and lower-leg casts are commonly combined to treat ankle equinus in children with spastic cerebral palsy (CP). However, the decomposed treatment effects on muscle or tendon structure, stretch reflexes, and joint are unknown. In this study, BoNT-A injections to the MG and casting of the lower legs were applied separately to gain insight into the working mechanisms of the isolated treatments on joint, muscle, and tendon levels. Thirty-one children with spastic CP (GMFCS I-III, age 7.4 ± 2.6 years) received either two weeks of lower-leg casts or MG BoNT-A injections. During full range of motion slow and fast passive ankle rotations, joint resistance and MG stretch reflexes were measured. MG muscle and tendon lengths were assessed at resting and at maximum dorsiflexion ankle angles using 3D-freehand ultrasound. Treatment effects were compared using non-parametric statistics. Associations between the effects on joint and muscle or tendon levels were performed using Spearman correlation coefficients (p < 0.05). Increased joint resistance, measured during slow ankle rotations, was not significantly reduced after either treatment. Additional joint resistance assessed during fast rotations only reduced in the BoNT-A group (−37.6%, p = 0.013, effect size = 0.47), accompanied by a reduction in MG stretch reflexes (−70.7%, p = 0.003, effect size = 0.56). BoNT-A increased the muscle length measured at the resting ankle angle (6.9%, p = 0.013, effect size = 0.53). Joint angles shifted toward greater dorsiflexion after casting (32.4%, p = 0.004, effect size = 0.56), accompanied by increases in tendon length (5.7%, p = 0.039, effect size = 0.57; r = 0.40). No associations between the changes in muscle or tendon lengths and the changes in the stretch reflexes were found. We conclude that intramuscular BoNT-A injections reduced stretch reflexes in the MG Peeters et al. Separate Effects of BoNT-A and Castingaccompanied by an increase in resting muscle belly length, whereas casting resulted in increased dorsiflexion without any changes to the muscle length. This supports the need for further investigation on the effect of the combined treatments and the development of treatments that more effectively lengthen the muscle.

“…Objective: The Functional Communication Classification System (FCCS) is valid and reliable for children with cerebral palsy (CP) aged 4-18 years. [1][2][3] This study investigated use for younger children with CP, aged 2 and 3 years. We examined: (i) inter-rater reliability between parents and a speech language pathologist (SLP); (ii) concurrent validity with the Language Use Inventory (LUI), a standardised pragmatic language assessment for children aged 18-47 months; and (iii) the relationship with motor classification (GMFCS-E&R, Mini-MACS) and associated impairments (vision, hearing, intelligence and epilepsy).…”

This review aimed to synthesise the literature reporting the use of magnetic resonance imaging (MRI) and ultrasound (US) measurements of muscle parameters in children with cerebral palsy to determine the breath of the current research in terms of participant demographics, muscles studied, muscle parameters reported on and commonalities or differences in techniques used.…”

AimsTo investigate the reliability, validity, and level of evidence of applying ultrasound in assessing the lower‐limb muscles of patients with cerebral palsy (CP).MethodPublications in Medline, PubMed, Web of Science, and Embase were searched on May 10, 2023, to identify and examine relevant studies investigating the reliability/validity of ultrasound in evaluating the architecture of CP lower‐limb muscles systematically, following the Preferred Reporting Items for Systematic Reviews and Meta‐Analysis 2020 guidelines.ResultsOut of 897 records, 9 publications with 111 CP participants aged 3.8–17.0 years were included (8 focused on intra‐rater and inter‐rater reliability, 2 focused on validity, and 4 were with high quality). The ultrasound‐based measurements of muscle thickness (intra‐rater only), muscle length, cross‐sectional area, muscle volume, fascicle length, and pennation angle showed high reliability, with the majority of intraclass correlation coefficient (ICC) values being larger than 0.9. Moderate‐to‐good correlations between ultrasound and magnetic resonance imaging measurements existed in muscle thickness and cross‐sectional area (0.62 ≤ ICC ≤ 0.82).InterpretationGenerally, ultrasound has high reliability and validity in evaluating the CP muscle architecture, but this is mainly supported by moderate and limited levels of evidence. More high‐quality future studies are needed.
