Vidmar T, Goljar Kregar N, Puh U. Reliability of the Modified Ashworth Scale After Stroke for 13 Muscle Groups. Arch Phys Med Rehabil 2023; 104:1606-1611. [PMID: 37121531 DOI: 10.1016/j.apmr.2023.04.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Revised: 03/07/2023] [Accepted: 04/06/2023] [Indexed: 05/02/2023]
Abstract
OBJECTIVE To evaluate the reliability of the protocol for administration of the Modified Ashworth Scale (MAS) for all commonly affected muscle groups after stroke. DESIGN A repeated-measures design was used in administration of MAS for 13 muscle groups on 2 assessment days. Intrarater reliability and interrater reliability (between 3 raters) was assessed. SETTING Inpatient rehabilitation. PARTICIPANTS 30 patients, 1-19 months after stroke (age 55.1±13.5 years; N=30). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURE Intra- and interrater reliability of the muscle tone assessment protocol with MAS for 7 upper and 6 lower limb muscle groups compiled from previous studies; 1 modified and 4 originally described. The weighted kappa was calculated. RESULTS The most and the least frequently assigned MAS grades were 0 and 4, respectively. Agreement was the highest for grade 0 (49% within raters, 32% between raters). Intrarater reliability was good to excellent for upper limb (κ=0.71-0.94) and moderate to excellent for lower limb (κ=0.55-0.97) muscles. Interrater reliability was poor to good for upper limb (κ=0.25-0.66) and moderate for lower limb (κ=0.41-0.54) muscles. CONCLUSIONS The intrarater reliability of MAS was moderate for the hip flexors. The reliability results for the other 4 muscles studied anew after stroke were similar to the predetermined ones. The better intrarater reliability results confirmed previous findings. Because of the low interrater reliability, caution is needed in interpreting the results when reassessment is not possible by the same examiner. A well-described protocol for administering the MAS may lead to its standardization.

Abe S, Yokoi Y, Kozuka N. Leg Cycling Leads to Improvement of Spasticity by Enhancement of Presynaptic Inhibition in Patients with Cerebral Palsy. Phys Ther Res 2023; 26:65-70. [PMID: 37621569 PMCID: PMC10445118 DOI: 10.1298/ptr.e10228] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Accepted: 05/18/2023] [Indexed: 08/26/2023]
Abstract
OBJECTIVE The purpose of this study was to investigate if leg cycling could reduce lower extremity spasticity in patients with cerebral palsy (CP). In addition, we investigated whether the intervention could cause changes in the modulation of presynaptic inhibition. METHODS This study was a quasi-experimental study, with pretest-posttest for 1 group. Participants in this experiment were eight adult patients with CP with lower extremity spasticity. Spasticity parameters assessed were the amplitude of soleus maximum Hoffmann's reflex (Hmax) and maximum angular velocity (MAV) of knee flexion measured using the pendulum test. D1 inhibition, which seems to be related to the presynaptic inhibition, was recorded by measuring soleus Hoffmann's reflex (H-reflex) with conditioned electric stimuli to the common peroneal nerve. RESULTS D1 inhibition was significantly enhanced immediately by the cycling intervention. The amplitude of the soleus Hmax was significantly depressed, and there was significant difference in Hmax/maximum M-wave. The MAV was increased due to inhibition of the stretch reflex. CONCLUSION Leg cycling suppressed stretch reflex and H-reflex, and caused plasticity of inhibitory circuits in patients with CP with lower extremity spasticity. These findings strongly suggest that lower extremity spasticity can be improved by cycling movements.

Abstract
PURPOSE Robotic gait training is relatively new in the world of pediatric rehabilitation. Preliminary feasibility studies and case reports include stationary robot-assisted treadmill training. Mobile robotic gait trainers hold greater promise for intensive practice-based therapy within hospitals, schools, rehabilitation centers, and at-home therapy as they enable participation and social integration while practicing high-quality gait patterns. MATERIALS AND METHODS This paper (clinical trials registry number: NCT05378243) provides a detailed description of a mixed-method cross-over trial design with a broad set of outcome measures. Ultimately the goal is to establish the feasibility of this design which includes the collection of qualitative data regarding patient, family, and therapist experience and quantitative data regarding gait efficiency and quality, impact on tone, individualized goal achievement and bone strength.

Abstract
PURPOSE To identify and appraise the literature on the psychometric properties of spasticity measures that have been used among children and adolescents with cerebral palsy (CP). METHODS A comprehensive literature search was conducted in 5 databases. Two independent reviewers screened the literature search results for relevant studies. Reviewers extracted the data using a standardized form and study quality was assessed using a critical appraisal tool. RESULTS A total of 44 studies met the selection criteria and were included. We identified 22 different spasticity assessment tools, with different levels of evidence regarding their psychometric properties. CONCLUSION The findings of the current review indicate that there is limited evidence to recommend 1 spasticity assessment method for children and adolescents with CP. Spasticity assessment in its current state lacks a method that possesses the necessary psychometric properties and is easily used in the clinical setting.

Abstract
The Modified Ashworth Scale (MAS) and Modified Tardieu Scale (MTS) are widely used to quantify spasticity. However, the reliability of their use for ankle plantar flexors has been questioned. In this study, we aimed to examine whether their reliabilities could be increased to acceptable levels for ankle plantar flexors using standardized movement speed in children with spastic cerebral palsy. The MAS and MTS scores for 92 limbs were assessed by two raters on two occasions, 1 week apart. A metronome was used to maintain the stretching velocity at 120 beats per minute. The intraclass correlation coefficients (ICCs) of the intra-rater reliabilities of the MAS and MTS and inter-rater reliability of the MAS were over 0.7. However, the ICCs for the inter-rater reliability of the MTS were <0.7 and >0.75 for the gastrocnemius and soleus muscles, respectively. The ICCs for the inter- and intra-rater reliabilities of the R1 angles ranged from 0.68 to 0.84, while those of the R2 angles ranged from 0.74 to 0.93. The reliabilities of the R2-R1 angles were not satisfactory. In conclusion, with a standardized movement speed, the reliability of the MAS for the ankle plantar flexors and the MTS for the soleus were satisfactory; however, that of the MTS for the gastrocnemius was not.

Abstract
AIMS To investigate the psychometric properties of the Selective Control of the Upper Extremity Scale (SCUES). METHODS Fifty-two children (27 females and 25 males; mean age 9.8 ± 4.4 years) with spastic type of cerebral palsy (CP) participated in the study. Psychometric analyses included reliability, concurrent validity, construct validity, and discriminant validity. Upper Limb Physician's Rating Scale (ULPRS), Modified Ashworth Scale (MAS), Quality of Upper Extremity Skills Test (QUEST) were used for concurrent validity. Manual Ability Classification System (MACS) was used for construct validity. Differences in SCUES scores were determined between participants categorized according to their limb distribution and MACS levels. RESULTS Intra-rater reliability (intraclass correlation coefficient [ICC] = 0.98) of the SCUES was excellent. SCUES and ULPRS (r = 0.87, p < 0.001), SCUES and MAS (r=-0.93, p < 0.001), SCUES and QUEST (r=0.81, p < 0.001) were highly correlated. SCUES and MACS (r=-0.67, p < 0.001) was moderately correlated. SCUES scores differed significantly between children classifed as MACS levels I versus II and III and between children with hemiparetic and diparetic CP. CONCLUSION The SCUES appears to be a valid and reliable tool to assess selective voluntary motor control of the upper extremities in children with spastic CP, which may be useful in selecting and planning interventions.

Abstract
BACKGROUND This study assessed the safety and efficacy of intrathecal injection of umbilical cord tissue mesenchymal stem cells (UCT-MSC) in individuals with cerebral palsy (CP). The diffusion tensor imaging (DTI) was performed to evaluate the alterations in white-matter integrity. METHODS Participants (4-14 years old) with spastic CP were assigned in 1:1 ratio to receive either UCT-MSC or sham procedure. Single-dose (2 × 107) cells were administered in the experimental group. Small needle pricks to the lower back were performed in the sham-control arm. All individuals were sedated to prevent awareness. The primary endpoints were the mean changes in gross motor function measure (GMFM)-66 from baseline to 12 months after procedures. The mean changes in the modified Ashworth scale (MAS), pediatric evaluation of disability inventory (PEDI), and CP quality of life (CP-QoL) were also assessed. Secondary endpoints were the mean changes in fractional anisotropy (FA) and mean diffusivity (MD) of corticospinal tract (CST) and posterior thalamic radiation (PTR). RESULTS There were 36 participants in each group. The mean GMFM-66 scores after 12 months of intervention were significantly higher in the UCT-MSC group compared to baseline (10.65; 95%CI 5.39, 15.91) and control (β 8.07; 95%CI 1.62, 14.52; Cohen's d 0.92). The increase was also seen in total PEDI scores (vs baseline 8.53; 95%CI 4.98, 12.08; vs control: β 6.87; 95%CI 1.52, 12.21; Cohen's d 0.70). The mean change in MAS scores after 12 months of cell injection reduced compared to baseline (-1.0; 95%CI -1.31, -0.69) and control (β -0.72; 95%CI -1.18, -0.26; Cohen's d 0.76). Regarding CP-QoL, mean changes in domains including friends and family, participation in activities, and communication were higher than the control group with a large effect size. The DTI analysis in the experimental group showed that mean FA increased (CST 0.032; 95%CI 0.02, 0.03. PTR 0.024; 95%CI 0.020, 0.028) and MD decreased (CST -0.035 × 10-3; 95%CI -0.04 × 10-3, -0.02 × 10-3. PTR -0.045 × 10-3; 95%CI -0.05 × 10-3, -0.03 × 10-3); compared to baseline. The mean changes were significantly higher than the control group. CONCLUSIONS The UCT-MSC transplantation was safe and may improve the clinical and imaging outcomes. TRIAL REGISTRATION The study was registered with ClinicalTrials.gov ( NCT03795974 ).

Abstract
In recent years, much attention has been paid to motor impairment of persons with Rett Syndrome (RTT), with increasing literature aimed to describe gross motor functioning and musculoskeletal disorders of the RTT population. The aim of this systematic review is to describe clinical evaluation tools used in the last decade to assess motor functioning and musculoskeletal abnormalities of patients with RTT. Thirty-four studies were reviewed and 20 tools were presented. Results showed that only two tools were used to measure functional change after rehabilitative or therapeutic interventions. This review underlies the lack of adequate evaluation tools to assess musculoskeletal abnormalities and deformities in RTT population. The absence of these assessments could be due to a statistical difficulty as it is challenging to build an evaluation tool that can score the entities of the abnormalities related to the amount of disability they cause.

Precise quantification of the time course of voluntary activation capacity following Botulinum toxin injections in the biceps brachii muscles of chronic stroke survivors.

Abstract
Background Spasticity is a key motor impairment that affects many hemispheric stroke survivors. Intramuscular botulinum toxin (BT) injections are used widely to clinically manage spasticity-related symptoms in stroke survivors by chemically denervating muscle fibers from their associated motor neurons. In this study, we sought to understand how BT affects muscle activation, motor unit composition and voluntary force generating capacity over a time period of 3 months. Our purpose was to characterize the time course of functional changes in voluntary muscle activity in stroke survivors who are undergoing BT therapy as part of their physician-prescribed clinical plan. Method Our assessment of the effects of BT was based on the quantification of surface electromyogram (sEMG) recordings in the biceps brachii (BB), an upper arm muscle and of voluntary contraction force. We report here on voluntary force and sEMG responses during isometric elbow contractions across consecutive recording sessions, spread over 12 weeks in three segments, starting with a preliminary session performed just prior to the BT injection. At predetermined time points, we conducted additional clinical assessments and we also recorded from the contralateral limbs of our stroke cohort. Eight subjects were studied for approximately 86 experimental recording sessions on both stroke-affected and contralateral sides. Results We recorded an initial reduction in force and sEMG in all subjects, followed by a trajectory with a progressive return to baseline over a maximum of 12 weeks, although the minimum sEMG and minimum force were not always recorded at the same time point. Three participants were able to complete only one to two segments. Slope values of the sEMG-force relations were also found to vary across the different time segments. While sEMG-force slopes provide assessments of force generation capacity of the BT injected muscle, amplitude histograms from novel sEMG recordings during the voluntary tasks provide additional insights about differential actions of BT on the overall motor unit (MU) population over time. Conclusions The results of our study indicate that there are potential short term as well as long term decrements in muscle control and activation properties after BT administration on the affected side of chronic stroke survivors. Muscle activation levels as recorded using sEMG, did not routinely return to baseline even at three months’ post injection. The concurrent clinical measures also did not follow the same time course, nor did they provide the same resolution as our experimental measures. It follows that even 12 weeks after intramuscular BT injections muscle recovery may not be complete, and may thereby contribute to pre-existing paresis.

Abstract
Care and research in childhood cerebral palsy (CP) continue to evolve. As our understanding of CP grows more nuanced, so grows our need to describe function, activities, challenges, adaptations of children with CP. In CP, robust means of measuring outcomes are vital to understanding utility of treatments. Research must accurately measure meaningful constructs of children with CP as a reliable ruler to establish if interventions produce useful effects. This article addresses the challenges of outcome measurement in CP, current status of outcome measurement in CP, and issues of understanding change in childhood CP.

Abstract
PURPOSE To identify child, family, and service determinants of playfulness of young children with cerebral palsy. METHODS Participants were 429 children, 18-60 months. Children were divided into two groups, Gross Motor Function Classification System levels I-II and III-V. Therapists collected data on body functions and gross motor function; parents provided information about children's health conditions and adaptive behavior, family life, and services. One year after the beginning of the study, therapists assessed children's playfulness. Data were analyzed using structural equation modeling. RESULTS Higher gross motor function was associated with higher playfulness for both groups. Greater impact of health conditions on daily life was associated with lower playfulness for children in levels I-II. More effective adaptive behavior was associated with higher playfulness, and higher parent perception of therapists' family-centeredness was associated with lower playfulness for children in levels III-V. CONCLUSION Supporting gross motor function, health, and adaptive behavior may foster playfulness.

Abstract
BACKGROUND Unilateral cerebral palsy (CP) is a condition that affects muscle control and function on one side of the body. Children with unilateral CP experience difficulties using their hands together secondary to disturbances that occur in the developing fetal or infant brain. Often, the more affected limb is disregarded. Constraint-induced movement therapy (CIMT) aims to increase use of the more affected upper limb and improve bimanual performance. CIMT is based on two principles: restraining the use of the less affected limb (for example, using a splint, mitt or sling) and intensive therapeutic practice of the more affected limb. OBJECTIVES To evaluate the effect of constraint-induced movement therapy (CIMT) in the treatment of the more affected upper limb in children with unilateral CP. SEARCH METHODS In March 2018 we searched CENTRAL, MEDLINE, Embase, CINAHL, PEDro, OTseeker, five other databases and three trials registers. We also ran citation searches, checked reference lists, contacted experts, handsearched key journals and searched using Google Scholar. SELECTION CRITERIA Randomised controlled trials (RCTs), cluster-RCTs or clinically controlled trials implemented with children with unilateral CP, aged between 0 and 19 years, where CIMT was compared with a different form of CIMT, or a low dose, high-dose or dose-matched alternative form of upper-limb intervention such as bimanual intervention. Primarily, outcomes were bimanual performance, unimanual capacity and manual ability. Secondary outcomes included measures of self-care, body function, participation and quality of life. DATA COLLECTION AND ANALYSIS Two review authors independently screened titles and abstracts to eliminate ineligible studies. Five review authors were paired to extract data and assess risk of bias in each included study. GRADE assessments were undertaken by two review authors. MAIN RESULTS We included 36 trials (1264 participants), published between 2004 and 2018. Sample sizes ranged from 11 to 105 (mean 35). Mean age was 5.96 years (standard deviation (SD) 1.82), range three months to 19.8 years; 53% male and 47% participants had left hemiplegia. Fifty-seven outcome measures were used across studies. Average length of CIMT programs was four weeks (range one to 10 weeks). Frequency of sessions ranged from twice weekly to seven days per week. Duration of intervention sessions ranged from 0.5 to eight hours per day. The mean total number of hours of CIMT provided was 137 hours (range 20 to 504 hours). The most common constraint devices were a mitt/glove or a sling (11 studies each).We judged the risk of bias as moderate to high across the studies. KEY RESULTS Primary outcomes at primary endpoint (immediately after intervention)CIMT versus low-dose comparison (e.g. occupational therapy)We found low-quality evidence that CIMT was more effective than a low-dose comparison for improving bimanual performance (mean difference (MD) 5.44 Assisting Hand Assessment (AHA) units, 95% confidence interval (CI) 2.37 to 8.51).CIMT was more effective than a low-dose comparison for improving unimanual capacity (Quality of upper extremity skills test (QUEST) - Dissociated movement MD 5.95, 95% CI 2.02 to 9.87; Grasps; MD 7.57, 95% CI 2.10 to 13.05; Weight bearing MD 5.92, 95% CI 2.21 to 9.6; Protective extension MD 12.54, 95% CI 8.60 to 16.47). Three studies reported adverse events, including frustration, constraint refusal and reversible skin irritations from casting.CIMT versus high-dose comparison (e.g. individualised occupational therapy, bimanual therapy)When compared with a high-dose comparison, CIMT was not more effective for improving bimanual performance (MD -0.39 AHA Units, 95% CI -3.14 to 2.36). There was no evidence that CIMT was more effective than a high-dose comparison for improving unimanual capacity in a single study using QUEST (Dissociated movement MD 0.49, 95% CI -10.71 to 11.69; Grasp MD -0.20, 95% CI -11.84 to 11.44). Two studies reported that some children experienced frustration participating in CIMT.CIMT versus dose-matched comparison (e.g. Hand Arm Bimanual Intensive Therapy, bimanual therapy, occupational therapy)There was no evidence of differences in bimanual performance between groups receiving CIMT or a dose-matched comparison (MD 0.80 AHA units, 95% CI -0.78 to 2.38).There was no evidence that CIMT was more effective than a dose-matched comparison for improving unimanual capacity (Box and Blocks Test MD 1.11, 95% CI -0.06 to 2.28; Melbourne Assessment MD 1.48, 95% CI -0.49 to 3.44; QUEST Dissociated movement MD 6.51, 95% CI -0.74 to 13.76; Grasp, MD 6.63, 95% CI -2.38 to 15.65; Weightbearing MD -2.31, 95% CI -8.02 to 3.40) except for the Protective extension domain (MD 6.86, 95% CI 0.14 to 13.58).There was no evidence of differences in manual ability between groups receiving CIMT or a dose-matched comparison (ABILHAND-Kids MD 0.74, 95% CI 0.31 to 1.18). From 15 studies, two children did not tolerate CIMT and three experienced difficulty. AUTHORS' CONCLUSIONS The quality of evidence for all conclusions was low to very low. For children with unilateral CP, there was some evidence that CIMT resulted in improved bimanual performance and unimanual capacity when compared to a low-dose comparison, but not when compared to a high-dose or dose-matched comparison. Based on the evidence available, CIMT appears to be safe for children with CP.

Abstract
Purpose When repairing retracted rotator cuff tears, the tear pattern (eg, crescent-shaped, L-shaped) is best determined intraoperatively by evaluating the mobility of the tendon in multiple directions. The purpose of our study was to evaluate the location of the supraspinatus (SSP) muscle belly on magnetic resonance imaging (MRI) in patients undergoing arthroscopic repair of retracted rotator cuff tears. We hypothesized that the location of the rotator cuff muscle would move after tendon repair, and that the perioperative change in muscle position would correlate with the tear pattern. Methods A series of primary arthroscopic repairs for rotator cuff tears with >3 cm of medial retraction from 2015 to 2016 was reviewed. MRIs were performed preoperatively and within 10 days postoperatively. The SSP muscle was assessed on sagittal MRI and evaluated for the “occupation ratio”, “tangent sign”, and the “location index” proposed in this study. Pre and postoperative MRIs were compared, and correlated with intraoperatively determined tear patterns. Fifty shoulders without rotator cuff pathology were also assessed for the “location index” as control. Results Fifty-nine shoulders (mean age 65.0 years) were included, among which five reverse L-shaped tears were identified. The occupation ratio and tangent sign improved postoperatively. Preoperatively, in the majority of tears, the SSP muscle was located more posteriorly in the SSP fossa, compared to the control group, and shifted anteriorly after repair. However, in reverse L-shaped tears the SSP muscle was located more centrally in the fossa, and shifted posteriorly following repair. Conclusion Rotator cuff tearing and arthroscopic rotator cuff repair change the location of the SSP muscle. Although repair usually results in shifting of the muscle belly from posterior to anterior, reverse L-shaped tears demonstrated an opposite pattern. The location of the SSP muscle belly may be useful in predicting tear patterns of retracted rotator cuff tears. Level of evidence Level IV (case series).

Abstract
Cerebral palsy (CP), a heterogeneous disorder of movement and posture, is one of the most important causes of disability affecting children. With a wide variability in the clinical presentation and a paucity of reliable diagnostic tests, decision-making in CP is fraught with difficulties and challenges. The plethora of musculoskeletal manifestations includes poor muscle function, spasticity, rigidity, muscle weakness, poor selective motor control, soft-tissue and joint contractures, torsional malalignments, and lever arm dysfunctions. Children with CP are at a high risk of further worsening and progression of these musculoskeletal abnormalities with the natural course of the disease. A comprehensive assessment that includes a combination of detailed medical history, functional assessment, clinical examination, analysis of gait, and radiological assessment is required to provide a favorable treatment outcome in these children. A close surveillance is essential so as to identify risk factors for the development and progression of musculoskeletal problems so that early interventions can be carried out to circumvent them. This review article is to highlight the importance of clinical examination in the assessment of children with CP.

Abstract
AIM To study the effects of single versus serial casting post-Botulinum toxin A (BoNT-A) injections on hypoextensibility of triceps surae in children, 2-7 years old, with cerebral palsy and equinus gait. METHODS A randomized, stratified, parallel, two-group trial was conducted at a pediatric health center with assessments at baseline, precast, postcast and, 1-, 2-, and 6-month follow-ups. One week following BoNT-A injections into triceps surae muscle, a single below-knee cast (n = 10) or 3 serial casts (n = 10) were applied for 3 weeks. Primary outcome measure was the Modified Tardieu Scale (MTS), secondary outcome measures were Modified Ashworth Scale (MAS), GAITRite™, Gross Motor Function Measure-66 (GMFM-66), and Pediatric Evaluation of Disability Inventory (PEDI). RESULTS Significant effects of time, but not group-by-time, were found for MTS R1 (P < 0.001), MTS R2 (P < 0.001), MAS (P = 0.001), GMFM-66 (P = 0.002), and PEDI (P < 0.001-0.009). One participant who received a single cast did not complete the 6-month assessment. CONCLUSIONS Magnitudes of improvements were similar using single or serial casting. If these findings are corroborated in a larger scale study, the recommendation of a single cast may be appropriate due to its greater convenience for families and clinicians.

Abstract
BACKGROUND Stiff-knee gait is a common gait deviation in individuals with cerebral palsy (CP) due to rectus femoris (RF) muscle spasticity. The Duncan-Ely test is a velocity-dependent measurement of spasticity that is recorded as positive or negative. At our institution, we use a modification of the Duncan-Ely test, a 5-point ordinal rating scale, which delineates where the catch occurs within the rapid arc of knee flexion. It has been named the Root-Ely test. QUESTIONS/PURPOSES We sought to determine the intra- and inter-rater reliability of the Duncan-Ely and Root-Ely tests in pediatric patients with CP. METHODS A convenience sample of 20 ambulatory subjects was recruited; mean age was 10.5 ± 4.5 years, and the Gross Motor Function Classification System (GMFCS) levels were I-III. Five clinicians measured each individual's RF spasticity using the Root-Ely protocol during a single visit. Simple κ statistics with 95% confidence intervals (CI) were utilized for intra-rater reliability and weighted κ statistics with 95% CI for inter-rater reliability. RESULTS The Root-Ely scale intra-rater reliability was 0.77 to 0.90 and inter-rater reliability was 0.32 to 0.87. Inter-rater reliability was good to excellent among experienced clinicians and fair to moderate in new clinicians. CONCLUSION The Root-Ely 5-point scale has acceptable intra- and inter-rater reliability in pediatric individuals with CP among experienced clinicians. The Root-Ely test allows experienced clinicians to reliably quantify severity of RF spasticity and may give orthopaedic surgeons a clinical tool to better predict ideal candidates for RF transfers in individuals with CP in order to improve stiff-knee gait.

Abstract
Hypertonia is the abnormal increase in muscle tone as a result of upper motor neuron lesions. There are three following clinical types: spasticity, dystonia, and rigidity. Management of hypertonia is individualized and should be directed by the patient and/or family׳s goals of care as well as the underlying cause of the hypertonia. Treatment options include stretching, strengthening, positioning, oral medications, botulinum toxin injections, phenol injections, as well as surgical procedures. Without effective management, hypertonia can result in muscle imbalance, abnormal movement patterns, pain, joint contracture, joint deformity, and ultimately negatively impact a patient׳s function. This discussion serves as an overview of hypertonia, focusing on spasticity and dystonia, in the pediatric population by examining the causes and epidemiology, elucidating its symptoms, discussing available treatment and management options, and clarifying why this all matters.

Abstract
Background. Even though lower-limb motor disorders are core features of spastic cerebral palsy (sCP), the relationship with brain lesions remains unclear. Unraveling the relation between gait pathology, lower-limb function, and brain lesions in sCP is complex for several reasons; wide heterogeneity in brain lesions, ongoing brain maturation, and gait depends on a number of primary motor functions/deficits (eg, muscle strength, spasticity). Objective. To use a comprehensive approach combining conventional MRI and diffusion tensor imaging (DTI) in children with sCP above 3 years old to relate quantitative parameters of brain lesions in multiple brain areas to gait performance. Methods. A total of 50 children with sCP (25 bilateral, 25 unilateral involvement) were enrolled. The investigated neuroradiological parameters included the following: (1) volumetric measures of the corpus callosum (CC) and lateral ventricles (LVs), and (2) DTI parameters of the corticospinal tract (CST). Gait pathology and primary motor deficits, including muscle strength and spasticity, were evaluated by 3D gait analysis and clinical examination. Results. In bilateral sCP (n = 25), volume of the LV and the subparts of the CC connecting frontal, (pre)motor, and sensory areas were most related to lower-limb functioning and gait pathology. DTI measures of the CST revealed additional relations with the primary motor deficits (n = 13). In contrast, in unilateral sCP, volumetric (n = 25) and diffusion measures (n = 14) were only correlated to lower-limb strength. Conclusions. These results indicate that the combined influence of multiple brain lesions and their impact on the primary motor deficits might explain a large part of the gait pathology in sCP.

Abstract
The World Health Organization's International Classification of Functioning, Disability and Health (ICF) provides an ideal framework within which to conceptualize grading and quantification of upper extremity function for children with spasticity. In this article the authors provide an overview of assessments and classification tools used to (1) understand upper extremity function associated with spasticity and the factors that contribute to dysfunction, (2) guide the selection of appropriate interventions, (3) identify specific muscles to target using surgical interventions and botulinum toxin-A injections, and (4) measure the outcomes of upper extremity interventions. Assessments of upper extremity function are briefly described and categorized as to whether they (1) measure children's best ability or actual performance in daily life, (2) are clinician administered or are a child/proxy report, (3) assist in planning intervention and/or measuring outcomes, and (4) evaluate unimanual or bimanual ability. In addition, measures of spasticity and hypertonicity, and classifications of static and dynamic upper extremity postures are summarized.

Abstract
PURPOSE We describe primary and secondary impairments in young children with cerebral palsy (CP); report differences in impairments on the basis of Gross Motor Function Classification System (GMFCS), age, and sex; and examine the extent that individual impairments account for the construct of primary and secondary impairments. METHODS Participants included 429 children with CP (242 [56%] male; 1½ to 5 years) representing all GMFCS levels. Reliable assessors collected primary and secondary impairment data using clinical measures. Analyses included descriptive statistics, comparisons among GMFCS, age, and sex, and factor analysis. RESULTS Young children with CP present with primary and secondary impairments. Significant differences in impairments occur among some GMFCS levels and age groups but not sex groups. Postural stability contributed most to primary impairments and strength to secondary impairments. CONCLUSION Young children with CP across GMFCS levels may have already developed secondary impairments that should be addressed within therapy services.

Do Three Different Passive Assessments of Quadriceps Spasticity Relate to the Functional Activity of Walking for Children Diagnosed with Cerebral Palsy? NEUROSCIENCE JOURNAL 2015; 2015:872015.

Abstract
A stiff-knee gait pattern is frequently associated with several impairments including quadriceps spasticity in children diagnosed with cerebral palsy (CP). The relationship of clinical measures of quadriceps spasticity and the stiff-knee gait pattern in children diagnosed with CP has not been well established. Therefore, the purpose of this study was to determine the ability of clinical measures of quadriceps spasticity (modified Ashworth scale [MAS], Ely tests, and pendulum test) to categorize a stiff-knee gait pattern in children with CP. Children were categorized as having a stiff-knee gait pattern based on kinematic and EMG gait data. Results of a logistic regression model revealed that the only significant measure was A1 of the pendulum test. Discriminant analysis functions were used to predict group membership (stiff-knee, not stiff-knee gait pattern) for each measure. The A1 of the pendulum test demonstrated the highest classification accuracy and the highest sensitivity compared to the other measures. Therefore, a negative pendulum test (indicated by an A1 value of 45 degrees or more) is more useful for ruling out a stiff-knee gait pattern compared to the other clinical measures.

Abstract
BACKGROUND Cerebral palsy is a disorder of movement and posture arising from a non-progressive lesion in the developing brain. Spasticity, a disorder of increased muscle tone, is the most common motor difficulty and is associated with activity limitation to varying degrees in mobility and self care.Oral baclofen, a gamma-aminobutyric acid (GABA) agonist, has been used in oral form to treat spasticity for some time, but it has a variable effect on spasticity and the dose is limited by the unwanted effect of excessive sedation. Intrathecal baclofen produces higher local concentrations in cerebrospinal fluid at a fraction of the equivalent oral dose and avoids this excessive sedation. OBJECTIVES To determine whether intrathecal baclofen is an effective treatment for spasticity in children with cerebral palsy. SEARCH METHODS We searched the CENTRAL, MEDLINE, EMBASE and CINAHL databases, handsearched recent conference proceedings, and communicated with researchers in the field and pharmaceutical and drug delivery system companies. SELECTION CRITERIA We included studies which compared the effect of intrathecal baclofen treatment on spasticity, gross motor function or other areas of function with controls. DATA COLLECTION AND ANALYSIS Two authors selected studies, two authors extracted data and two authors assessed the methodological quality of included studies. MAIN RESULTS Six studies met the inclusion criteria. The data obtained were unsuitable for the conduct of a meta-analysis; we have completed a qualitative summary.All studies were found to have high or unclear risk of bias in some aspects of their methodology.Five of the six studies reported data collected in the randomised controlled phase of the study. A sixth study did not report sufficient results to determine the effect of intrathecal baclofen versus placebo. Of these five studies, four were conducted using lumbar puncture or other short-term means of delivering intrathecal baclofen. One study assessed the effectiveness of implantable intrathecal baclofen pumps over six months.The four short-term studies demonstrated that intrathecal baclofen therapy reduces spasticity in children with cerebral palsy. However, two of these studies utilised inappropriate techniques for statistical analysis of results. The single longer-term study demonstrated minimal reduction in spasticity with the use of intrathecal baclofen therapy.One of the short-term studies and the longer term study showed improvement in comfort and ease of care. The longer term study found a small improvement in gross motor function and also in some domains of health-related quality of life.Some caution is required in interpreting the findings of the all the studies in the review due to methodological issues. In particular, there was a high risk of bias in the methodology of the longer term study due to the lack of placebo use in the control group and the absence of blinding to the intervention after randomisation for both participants and investigators. AUTHORS' CONCLUSIONS There is some limited short-term evidence that intrathecal baclofen is an effective therapy for reducing spasticity in children with cerebral palsy. The effect of intrathecal baclofen on long-term spasticity outcomes is less certain.The validity of the evidence for the effectiveness of intrathecal baclofen in treating spasticity in children with cerebral palsy from the studies in the review is constrained by the small sample sizes of the studies and methodological issues in some studies.Spasticity is a impairment in the domain of body structure and function. Consideration must also be given to the broader context in determining whether intrathecal baclofen therapy is effective. The aim of therapy may be, for example, to improve gross motor function, to increase participation at a social role level, to improve comfort, to improve the ease of care by others or to improve the overall quality of life of the individual. Intrathecal baclofen may improve gross motor function in children with cerebral palsy, but more reliable evidence is needed to determine this.There is some evidence that intrathecal baclofen improves ease of care and the comfort and quality of life of the individuals receiving it, but again small sample sizes and methodological issues in the studies mean that these results should be interpreted with caution.Further evidence of the effectiveness of intrathecal baclofen for treating spasticity, increasing gross motor function and improving comfort, ease of care and quality of life is needed from other investigators in order to validate these results.The short duration of the controlled studies included in this review did not allow for the exploration of questions regarding whether the subsequent need for orthopaedic surgery in children receiving intrathecal baclofen therapy is altered, or the safety and the economic implications of intrathecal baclofen treatment when long-term therapy is administered via an implanted device. Controlled studies are not the most appropriate study design to address these questions, cohort studies may be more appropriate.

[PMID: 26504273 PMCID: PMC4616074 DOI: 10.1589/jpts.27.2705] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2015] [Accepted: 05/25/2015] [Indexed: 11/24/2022] Open
Abstract
[Purpose] The purpose of this study was to investigate the relationship of knee proprioception with muscle strength and spasticity in stroke patients. [Subjects and Methods] The subjects were 31 stroke patients. The subjects received an explanation of the procedures and methods and provided informed consent before the experiment. A measurement board was used to determine the the proprioception deficit of the knee as a proprioception test. The proprioception test consisted of a passive and active angle reproduction test. A manual muscle test and modified Ashworth scale were used to evaluate knee muscle strength and spasticity level. The data were analyzed using an independent t-test and Spearman correlation. [Results] The results of this study revealed a significant difference between the affected side and non-affected side in the passive angle reproduction test and a significant difference in the correlation of the proprioception level with muscle strength and spasticity level. [Conclusion] This study indicates that the knee proprioception level is associated with spasticity and muscle strength in stroke patients.

Abstract
Background. To investigate the effectiveness of upper limb rehabilitation, sound measures of upper limb function, capacity, and performance are paramount. Objectives. This systematic review investigates reliability and responsiveness of upper limb measurement tools used in pediatric neurorehabilitation. Methods. A 2-tiered search was conducted up to July 2014. The first search identified upper limb motor assessments for 1- to 18-year-old children with neuromotor disorders. The second search examined the psychometric properties of the tools. Methodological quality was rated according to COSMIN guidelines, and results for each tool were assembled in a “best evidence synthesis.” Furthermore, we delineated whether tools were unimanual or bimanual tests and if they measured recovery or did not distinguish between physiological and compensatory movements. Results. The first search delivered 2546 hits. Of these, 110 articles on 51 upper limb assessment tools were included. The second search resulted in 58 studies on reliability, 11 on measurement error, and 10 on responsiveness. Best evidence synthesis revealed only 2 assessments with moderate positive evidence for reliability, whereas no evidence on measurement error and responsiveness was found. The Melbourne Assessment showed moderate positive evidence for interrater and a fair positive level of evidence for intrarater reliability. The Pediatric Motor Activity Log Revised revealed moderate positive evidence for test–retest reliability. Conclusions. There is a lack of high-quality studies about psychometric properties of upper limb measurement tools in children with neuromotor disorders. To date, upper limb rehabilitation trials in children and adolescents risk being biased by insensitive measurement tools lacking reliability.

Abstract
BACKGROUND AND PURPOSE This case report describes an aggressive, task-specific program for the recovery of gait in a girl with a spinal cord stroke. CASE DESCRIPTION The 11-year-old girl sustained a spinal cord stroke resulting in a T4 motor-incomplete lesion. Therapy was initiated 6 months after onset when she was not ambulating. INTERVENTION The focus of all interventions was on the restoration of gait. Locomotor treadmill training and over ground walking were the primary practice interventions. Walking was facilitated by orthoses, neuromuscular electrical stimulation, laser treatments, and strengthening. Treatment continued for 18 months. OUTCOMES At the conclusion of therapy, the client was able to walk independently in the community with a single ankle foot orthosis and reverse rolling walker. DISCUSSION The outcome was not anticipated for this client, given the type and level of her injury and the delay in starting gait training.

Abstract
PURPOSE The aim of this study was to evaluate the effect of dynamic elastomeric fabric orthoses (DEFOs) on postural control in children with cerebral palsy (CP). METHODS Ten children with spastic diplegic CP and 10 children with typical development participated. Knee extension was measured using electrogoniometry. The standard deviation of excursion and phase plane portraits of velocity in the anteroposterior and mediolateral directions were calculated from force platform signals as center of pressure parameters with or without a DEFO. RESULTS Maximum standing knee extension for children with CP improved after 6 weeks of wearing DEFOs (P < .05). Center of pressure parameters did not improve when comparing pre- to 6 weeks post-DEFO use (P < .05). CONCLUSION The DEFO can reduce the crouch position without any negative effect on postural stability in children with CP. However, postural control does not improve in a 6-week timeframe.

Abstract
OBJECTIVE To test a model of child, family and service determinants of self-care participation of children with cerebral palsy (CP), grouped by Gross Motor Function Classification System levels (I-II and III-V). METHODS Participants were a convenience sample of 429 children (242 males) with CP, aged 18-60 months. Data on impairments and gross motor function were collected by reliable therapists; parents provided information about children's health conditions and adaptive behaviour. Seven months later parents reported on family life and services received. One year after study onset, parents documented children's self-care participation. Data from two groups of children were analysed using structural equation modelling. RESULTS The model explained a significant proportion of the variance of self-care participation, with higher motor function, fewer health conditions and higher levels of adaptive behaviour being associated with greater self-care participation. CONCLUSION Supporting children's gross motor function, health and adaptive behaviour may optimize self-care participation.

Abstract
Cerebral palsy describes a group of disorders of movement and posture that result from disturbances in the developing brain. Although the brain lesion is nonprogressive, the secondary physical symptoms change with time and growth. If left untreated, symptoms may result in the development of physical impairment and impede independent performance of daily tasks. Intramuscular injection of botulinum neurotoxin A is a relatively safe and effective adjunct to upper limb therapy. Botulinum neurotoxin A primarily aims to reduce muscle overactivity, thereby reducing the development of increased muscle stiffness that can lead to permanent changes. With a specific focus on the physiological action of botulinum neurotoxin A, this article describes the secondary symptoms of cerebral palsy and their different contributions. To highlight research directions and future implications for clinical practice, this article also documents the recent scientific evidence for upper limb botulinum neurotoxin A and proposes a preventive clinical model that aims to mitigate the effects of increasing upper limb impairment.

Abstract
PURPOSE This study examined body-scaled information that specifies the reach patterns of children with hemiplegic cerebral palsy and children with typical development. METHODS Nine children with hemiplegic cerebral palsy (3-5 years) and 9 age-matched children with typical development participated in the study. They were required to reach and grasp 10 different pairs of cubes. Reach data were coded as either a 1-handed reach or a 2-handed reach. Dimensionless ratios were calculated by dividing the cube size by the maximal aperture between the index finger and thumb. A critical ratio was used to establish the shift from a 1-handed to an exclusive 2-handed reach. RESULTS The critical ratio was not significantly different for either preferred or nonpreferred arms within and between groups. All children used an exclusive 2-handed reach at a similar dimensionless ratio. CONCLUSION Our study provides evidence of the "fit" between environment (cube size) and the individual's capabilities (finger aperture) for reaching for both groups.

Abstract
This study investigated patterns of motor brain activation, white matter (WM) integrity of inter- and intrahemispheric connectivity and their associations with hand function in children with unilateral cerebral palsy (CP-U). Fourteen CP-U (mean age 10.6 ± 2.7 years) and 14 typically developing children (TDC) underwent magnetic resonance imaging. CP-U underwent extensive motor evaluation. Pattern of brain activation during a motor task was studied in 12 CP-U and six TDC, by calculating laterality index (LI) and percent activation in the sensorimotor areas (around the central sulcus), and quantifying the activation in the supplementary motor area (SMA). Diffusivity parameters were measured in CP-U and eight other TDC for the corpus callosum (CC), affected and less affected cortico-spinal tracts (CST), and posterior limb of the internal capsule (PLIC). Abnormal patterns of brain activation were detected in areas around the central sulcus in 9/12 CP-U, with bilateral activation and/or reduced percent activation. More activation in areas around the central sulcus of the affected hemisphere was associated with better hand function. CP-U demonstrated more activation in the SMA when moving the affected hand compared to the less affected hand. CP-U displayed reduced WM integrity compared to TDC, in the midbody and splenium of the CC, affected CST and affected PLIC. WM integrity in these tracts was correlated with hand function. While abnormal pattern of brain activation was detected mainly when moving the affected hand, the integrity of the CC was correlated with function of both hands and bimanual skills. This study highlights the importance of interhemispheric connectivity for hand function in CP-U, which may have clinical implications regarding prognosis and management.

Abstract
BACKGROUND AND PURPOSE The purpose of this case report is to describe physical therapy interventions used and gross motor functional outcomes achieved during a 3-week course of constraint-induced movement therapy for a child with cerebral palsy. CASE DESCRIPTION A 10-year-old boy with spastic triplegic cerebral palsy underwent fine and gross motor interventions to force use of the left extremities and right lower extremity. INTERVENTION For weeks 1 to 2, he received 2 occupational and physical therapy sessions each week. For weeks 3 to 5, he participated in constraint-induced movement therapy, while wearing a cast 90% of waking hours. OUTCOMES The Gross Motor Function Measure-88 score increased from 44.55% to 62.35% after treatment. Although he improved in one area of the Functional Independence Measure for Children, he demonstrated remarkable progress in his ability to bear weight and shift weight to his involved side in various developmental positions.

Abstract
BACKGROUND Insights in upper limb impairments and their relationship with activity measures in children with unilateral cerebral palsy (CP) are important to optimize treatment interventions. AIMS (1) To investigate upper limb impairments and activity limitations in children with unilateral CP; (2) to compare these according to the Manual Ability Classification System (MACS), timing of lesion (congenital/acquired) and age; (3) to determine the impact of impairments on activity measures. METHODS Eighty-one children with unilateral CP aged 5-15 years (mean 9 years 11 months; congenital N=69, acquired N=12) were recruited. Body function measurements included passive range of motion (PROM), muscle tone, strength and sensibility. At activity level, the Melbourne Assessment, Assisting Hand Assessment (AHA) and Abilhand-Kids were assessed. RESULTS Most PROM limitations were found for elbow extension and supination. Increased tone and weakness were most prominent in distal muscles. Stereognosis and two-point discrimination were mostly affected. Children with a lower MACS level or acquired lesion had significantly more impairments and activity limitations. In children with congenital lesions, best predictors for unimanual capacity (Melbourne Assessment) were wrist strength, stereognosis and proprioception, and for bimanual performance (AHA) wrist strength and grip strength, explaining 76% of the variance. For the Abilhand-Kids, wrist strength and stereognosis predicted 46% of the variance. CONCLUSIONS Classification according to MACS and timing of lesion is important to differentiate within the wide range of impairments and activity limitations. In children with congenital lesions, unimanual capacity and bimanual performance are highly determined by distal strength, supporting the additional use of impairment-based interventions.

Abstract
This paper presents the framework for developing a robotic system to improve accuracy and reliability of clinical assessment. Clinical assessment of spasticity tends to have poor reliability because of the nature of the in-person assessment. To improve accuracy and reliability of spasticity assessment, a haptic device, named the HESS (Haptic Elbow Spasticity Simulator) has been designed and constructed to recreate the clinical "feel" of elbow spasticity based on quantitative measurements. A mathematical model representing the spastic elbow joint was proposed based on clinical assessment using the Modified Ashworth Scale (MAS) and quantitative data (position, velocity, and torque) collected on subjects with elbow spasticity. Four haptic models (HMs) were created to represent the haptic feel of MAS 1, 1+, 2, and 3. The four HMs were assessed by experienced clinicians; three clinicians performed both in-person and haptic assessments, and had 100% agreement in MAS scores; and eight clinicians who were experienced with MAS assessed the four HMs without receiving any training prior to the test. Inter-rater reliability among the eight clinicians had substantial agreement (κ = 0.626). The eight clinicians also rated the level of realism ( 7.63 ± 0.92 out of 10) as compared to their experience with real patients.

Abstract
BACKGROUND In children with unilateral cerebral palsy (CP), development of arm and hand function is often compromised by the underlying motor and sensory impairments. However, knowledge about the evolution of arm and hand function in this population is limited. AIM The aims were to map the evolution of scores on upper limb measures over one year in children with unilateral CP and to identify factors that influence time trends. METHODS Eighty-one children (43 males, 38 females; mean age 9y11mo (SD 3y3mo) range 5-15 y) were tested at baseline, at 6 and 12 months. According to the International Classification of Functioning, Disability and Health, body function measurements included passive range of motion, muscle tone, manual muscle strength and grip strength. Activity measurements included the Melbourne Assessment, the Jebsen-Taylor test, the Assisting Hand Assessment and the Abilhand-Kids questionnaire. Age, gender, etiology (congenital or acquired lesions) and Manual Ability Classification System (MACS) levels were analyzed as predictive factors, using mixed models. RESULTS Scores for grip strength (p = 0.001) and manual dexterity (Jebsen-Taylor test, p < 0.0001) increased significantly over time. MACS level (p = 0.03) and etiology (p = 0.02) had a significant influence on the time evolution of the Jebsen-Taylor scores. Other assessments showed no significant changes. CONCLUSION Motor impairments, movement quality and hemiplegic hand use in bimanual tasks do not spontaneously improve over one year, except for an age-related change in grip strength. However, an improvement was observed in manual dexterity, suggesting that some children can learn more adaptive movement strategies.

Abstract
BACKGROUND Children with cerebral palsy (CP) often demonstrate postural control difficulties. Orthotic management may assist in improving postural control in these children. OBJECTIVE The purpose of this investigation was to examine the influence of floor reaction ankle foot orthosis (FRAFO) on postural flexion called the crouch position in children with CP. STUDY DESIGN Quasi-experimental. METHODS Eight children with spastic diplegic CP and eight matched typically developing children participated in this study. Postural control of children with CP was assessed in a static standing position on a force platform with/without a FRAFO. The parameters used were centre of pressure (CoP) measures, calculated from force platform signals including the standard deviation (SD) of excursion; phase plate portrait and SD of velocity in anteroposterior (AP) and mediolateral (ML) directions. RESULTS The maximum knee extension was statistically significant in children with CP when barefoot compared to wearing braced footwear (p < 0.05, t = 10.01). AP and ML displacement, AP velocity and AP phase plate portrait of CoP were not statistically significant between children with CP with/without a FRAFO (p < 0.05). CONCLUSION FRAFO can improve the alignment of the knee, but may not be helpful in improving postural control in children with CP in a short time period.

Abstract
AIM Conventional constraint-based therapies are intensive and demanding to implement, particularly for children. Modified forms of constraint-based therapies that are family-centred may be more acceptable and feasible for families of children with cerebral palsy (CP)-but require rigorous evaluation using randomized trials. The aim of this study was to determine the effects of modified constraint-induced therapy compared with intensive occupational therapy on activities of daily living and upper limb outcomes in children with hemiplegic CP. METHOD In this assessor-blinded pragmatic randomized trial, 50 children (27 males, 23 females; age range 19 mo-7 y 10 mo) with hemiplegic CP were randomized using a concealed allocation procedure to one of two 8-week interventions: intensive occupational therapy (n = 25), or modified constraint-induced therapy (n = 25). Manual Ability Classification System (MACS) levels of the participants were, level I n = 2, II n = 37, III n = 8, and level IV n = 1; Gross Motor Function Classification System (GMFCS) levels were, level I n = 33, level II n = 15, and level III n = 1. Participants were recruited through three specialist CP centres in Australia and randomized between January 2008 and April 2010. Children randomized to modified constraint-induced therapy wore a mitt on the unaffected hand for 2 hours each day, during which time the children participated in targeted therapy. The primary outcome was the Canadian Occupational Performance Measure (COPM--measured on a 10-point scale) at completion of therapy. Other outcome measures were Goal Attainment Scaling, Assisting Hand Assessment, Pediatric Motor Activity Log, Modified Ashworth Scale, Modified Tardieu Scale, and a parent questionnaire. Assessments were carried out at 10 weeks and 6 months following randomization. RESULTS All participants were included in the analysis. Between-group differences for all outcomes were neither clinically important nor statistically significant. The mean difference in COPM was 0.3 (95% confidence interval [CI] -0.8 to 1.4; p=0.61) and mean difference in COPM satisfaction was 0.1 (95% CI -1.1 to 1.2; p=0.90). Minor adverse events were reported by five of the 25 participants in the modified constraint-induced therapy group and by one of the 25 in the intensive occupational therapy group. All adverse events were related to participants' lack of acceptance of therapy. INTERPRETATION Modified constraint-induced therapy is no more effective than intensive occupational therapy for improving completion of activities of daily living or upper limb function in children with hemiplegic CP.

Abstract
Caregivers of persons with profound intellectual and multiple disabilities (PIMD) often describe the quality of the daily movements of these persons in terms of flexibility or stiffness. Objective outcome measures for flexibility and stiffness are muscle tone or level of spasticity. Two instruments used to grade muscle tone and spasticity are the Modified Ashworth Scale (MAS) and the Modified Tardieu Scale (MTS). To date, however, no research has been performed to determine the psychometric properties of the MAS and MTS in persons with PIMD. Therefore, the purpose of this study was to determine the feasibility, test-retest reliability, and interrater reliability of the MAS and MTS in persons with PIMD. We assessed 35 participants on the MAS and MTS twice, first for the test and second a week later for the retest. Two observers performed the measurements. Feasibility was assessed based on the percentage of successful measurements. Test-retest and interrater reliability were determined by using the Wilcoxon signed rank test, intraclass correlation coefficients (ICC), Spearman's correlation, and either limits of agreement (LOA) or quadratically weighted kappa. The feasibility of the measurements was good, because an acceptable percentage of successful measurements were performed. MAS measurements had substantial to almost perfect quadratically weighted kappa (>0.8) and an acceptable ICC (>0.8) for both inter- and intrarater reliability. However, MTS measurements had insufficient ICCs, Spearman's correlations, and LOAs for both inter- and interrater reliability. Our data indicated that the feasibility of the MAS and MTS for measuring muscle tone in persons with PIMD was good. The MAS had sufficient test-retest and interrater reliability; however, the MTS had an insufficient test-retest and interrater reliability in persons with PIMD. Thus, the MAS may be a good method for evaluating the quality of daily movements in persons with PIMD. Providing test administrators with training and clear instructions will improve test reliability.

Abstract
PURPOSE To establish interrater and test-retest reliability of a clinical assessment of motor and sensory upper limb impairments in children with hemiplegic cerebral palsy aged 5-15 years. METHOD The assessments included passive range of motion (PROM), Modified Ashworth Scale (MAS), manual muscle testing (MMT), grip strength, the House thumb and Zancolli classification and sensory function. Interrater reliability was investigated in 30 children, test-retest reliability in 23 children. RESULTS For PROM, interrater reliability varied from moderate to moderately high (correlation coefficients 0.48-0.73) and test-retest reliability was very high (>0.81). For the MAS and MMT, total score and subscores for shoulder, elbow, and wrist showed a moderately high to very high interrater reliability (0.60-0.91) and coefficients of >0.78 for test-retest reliability. The reliability for the individual muscles varied from moderate to high. The Jamar dynamometer was found to be highly reliable. The House thumb classification showed a substantial reliability and the Zancolli classification an almost perfect reliability. All sensory modalities had a good agreement. CONCLUSIONS For all motor and sensory assessments, interrater and test-retest reliability was moderate to very high. Test-retest reliability was clearly higher than interrater reliability. To improve interrater reliability, it was recommended to strictly standardize the test procedure, refine the scoring criteria and provide intensive rater trainings.

Abstract
This perspective article provides an example of a study planned using guidelines for comprehensive rehabilitation outcomes research, an approach that is believed to give service providers meaningful evidence to support practice. This line of investigation has been guided by the World Health Organization's International Classification of Functioning, Disability and Health. The short title of a study under way is Move & PLAY (Movement and Participation in Life Activities of Young Children). The article briefly describes the conceptual model, provides guidelines on how indicators and measures are selected, alludes to the details of selected measures, and describes processes of preparing for data collection, including obtaining ethics approval, preparing data collection booklets, training assessors and interviewers, and sampling. The aim of this investigation is to gain a better understanding of the multiple child, family, and service factors associated with changes in mobility, self-care, and play of preschool children with cerebral palsy as a result of using this research method. Comprehensive rehabilitation outcomes research holds promise in providing evidence that supports the complexities of planning rehabilitation services with clients with chronic conditions, such as children with cerebral palsy.

Abstract
AIMS In this study the aim was to evaluate the effect of botulinum toxin A (BoNT-A) treatment on muscle tone, contracture development and gait pattern in young children with cerebral palsy (CP). METHOD Fifteen children with spastic CP (mean age = 16 months) were included in a randomized control study. All received a daily stretching programme and children in the BoNT-A group additionally received two injections, 6 months apart in the gastrocnemius muscle. Outcomes were assessed at baseline, and after 1 and 3.5 years. A 3D gait-analysis was performed at 5 years of age. RESULTS Plantarflexor muscle tone in the BoNT-A group was significantly reduced after 3.5 years, while the muscle tone at the ankle and knee in the control group remained unchanged. The change-score in knee-flexion muscle tone between the groups was significantly different after 3.5 years. The knee joint ROM was significantly increased at 1 year in the BoNT-A group but reduced at the knee and ankle joints in the control group after 3.5 years. No group differences were found for gait analysis, GMFM-66 or PEDI. CONCLUSION Early treatment of BoNT-A in children with spastic CP may decrease muscle tone and decelerate contracture development after 3.5 years. The effect on gait development remains inconclusive.

Abstract
PRIMARY OBJECTIVE To assess the inter-rater reliability of the Modified Modified Ashworth Scale (MMAS) in lower limb muscle spasticity. RESEARCH DESIGN Cross-sectional observational study. INTERVENTIONS Not applicable. METHODS AND PROCEDURES Twenty-two adults with neurological conditions (17 women, five men, age range 21-82 years; mean +/- SD, 44 +/- 18 years) participated. Hip adductor, knee extensor and ankle plantarflexor were assessed in a random order. MAIN OUTCOMES AND RESULTS Inter-rater agreement for two raters was very good for the hip adductor and the knee extensor (weighted kappa = 0.82, p < 0.0001) and good for the ankle plantarflexor (weighted kappa = 0.74, p < 0.0001). CONCLUSIONS The Modified Modified Ashworth Scale produced reliable measurements between raters in the assessment of lower limb muscle spasticity.

Abstract
Describing the status of children with cerebral palsy (CP) and quantifying change in their status are 2 central challenges to research and clinical management of CP. The science of assessing and reporting status is outcome measurement, and it is rapidly developing in the arena of CP. Because of the large number of domains to measure, the variability of CP manifestations, and a limited number of "gold standard" evaluations, creating an accurate, comprehensive, responsive, and broadly applicable measurement strategy is a serious endeavor. A range of outcome measures are available to address CP issues across the spectrum of disability. The use of these measures, and others yet to be developed, provides researchers and clinicians the best means of understanding CP and the effects of treatments.

Abstract
The long-term effects of botulinum toxin A (BoNT-A) treatment in children with cerebral palsy (CP) are still elusive. We studied a prospective clinical cohort of 94 children with different subtypes (50% spastic diplegic CP, 22% hemiplegic CP, 25% tetraplegic CP, 3% dyskinetic CP), sex (55% male, 45% female), severity according to Gross Motor Function Classification System (29% Level I, 15% Level II, 16% Level III, 17% Level IV, 23% Level V), and age (median 5y 4mo, range 11mo-17y 8mo). The longest follow-up time was 3 years 7 months (median 1y 6mo) and included a maximum of eight injections per muscle (median two injections to a specific muscle). Outcome measurements were muscle tone (Modified Ashworth Scale) and joint range of motion (ROM). Assessments were made at a minimum before and 3 months after each injection. Ninety-five per cent confidence intervals for differences from baseline were used to identify significant changes. BoNT-A injections induced reduction of long-term spasticity in all muscle-groups examined: the gastrocnemius, hamstring, and adductor muscles. The reduction in tone was most distinct in the gastrocnemius muscle, and each repeated injection produced an immediate reduction in muscle tone. However, improvement in ROM was brief and measured only after the first injections, whereupon the ROM declined. Thus, the results suggest that BoNT-A can be effective in reducing muscle tone over a longer period, but not in preventing development of contractures in spastic muscles. The dissociation between the effects on muscle tone and ROM indicates that development of contractures is not coupled to increased muscle tone only, but might be caused by other mechanisms.

Abstract
Muscle spasticity is a common motor disorder following upper motor neuron syndrome. A reliable and valid clinical tool is essential to document the effect of therapeutic interventions aimed to improve function by reducing spasticity. The Modified Ashworth Scale (MAS) is the most widely used and accepted clinical scale of spasticity. The MAS has been recently modified. The aim of this investigation was to determine the interrater and intrarater reliability of clinical test of knee extensor post-stroke spasticity graded on a Modified Modified Ashworth Scale (MMAS). Two raters scored the muscle spasticity of 15 patients with ischaemic stroke. For the inter- and intrarater reliability, two raters agreed on 80.1% and 86.6%, respectively. The Kappa values were good (kappa=0.72, SE=0.14, p<0.001) between raters and very good (kappa=0.82, SE=0.12, p<0.001) within one rater. The values of Kendall tau-b correlation were acceptable for clinical use with 0.87 (SE=0.06, p<0.001) between raters and 0.92 (SE=0.05, p<0.001) within one rater. The MMAS demonstrated reliable measurements for a single rater and between raters for measuring knee extensor post-stroke spasticity. The results encourage further study on the reliability and the validity of the scale.

Abstract
BACKGROUND Measurement of spasticity is a difficult and unresolved problem, partly due to its complexity and the fact that there are many factors involved. In the assessment of spasticity in the pediatric disabled population, methods that are easily used in practice are ordinal scales that still lack reliability. A prospective cross-sectional observational study was planned to determine the reliability of the Ashworth Scale (AS) and the Modified Ashworth Scale (MAS) in children with spastic cerebral palsy (CP). METHODS The study included 38 children with spastic diplegic CP. The mean age for the children was 52.9 months (SD: 19.6) ranging from 18 to 108 months. The functional levels of children were classified according to the Gross Motor Function Classification System. 20 children were in Level II (52.6%), 18 were in Level III (47.4%) and 9 were in Level I (23.7%). Spasticity in hip flexors, adductors, internal rotators, hamstrings, gastrocnemius were assessed by AS and MAS. Each child was assessed by three physiotherapists in two different sessions, a week apart. The intrarater reliability was determined by paired comparison of measurements for each therapist for the two assessments. Interrater reliability was determined by paired comparisons of the three therapists' measurements on the same day. The inter and intrarater reliability of the scales were evaluated by the intraclass correlation coefficient (ICC). RESULTS According to ICC scores, interrater reliability of AS and MAS varied from moderate to good. ICC scores of AS were between 0.54 and 0.78 and MAS were between 0.61-0.87. Test-retest results of AS and MAS varied from poor to good. ICC values were between 0.31 and 0.82 for AS and between 0.36 and 0.83 for MAS. CONCLUSION The interrater and intrarater reliability of AS and MAS are related to muscle and joint characters. The repetition of measurements by the same physiotherapist, and experience may not affect reliability. These scales are not very reliable and assessments of spasticity using these scales should be therefore interpreted with great caution.

Abstract
PURPOSE The purpose of this study was to investigate feasibility of an assessment protocol for a trial of post-Botox casting to treat equinus gait in cerebral palsy. METHODS Ten children (ages, 26-75 months) were recruited. Nine were assessed 1 week before botulinum toxin-A injections and reassessed 1 week after removal of the final cast. The assessment protocol included Modified Ashworth Scale (MAS), Modified Tardieu Scale (MTS), Gross Motor Function Measure-66 (GMFM-66), Pediatric Evaluation of Disability Inventory (PEDI), and GAITRite. Feasibility was based on acceptability of the protocol, inter-rater reliability, and responsiveness of outcome measures. RESULTS The assessment protocol was acceptable and practical. Inter-rater reliability for MAS, MTS, and GMFM ranged from moderate to excellent. Improvements were found in MTS and MAS scores for dorsiflexion and hamstring (p < 0.01), GMFM-66 (p = 0.01), and Pediatric Evaluation of Disability Inventory mobility (p = 0.01), self-care (p = 0.01), and social function (p = 0.00). GAITRite revealed reductions in speed (p = 0.00) and cadence (p = 0.01). CONCLUSIONS Feasibility was confirmed. Recommendations include raising minimum age and delaying gait analysis.
