A systematic review of instrumented assessments for upper limb function in cerebral palsy: current limitations and future directions.

INTRODUCTION: Recently, interest in quantifying upper limb function in cerebral palsy has grown. However, the lack of reference tasks and protocols, have hindered the development of quantified movement analysis in clinical practice. This study aimed to evaluate existing instrumented assessments of upper limb function in cerebral palsy, with a focus on their clinical applicability, to identify reasons for the lack of adoption and provide recommendations for improving clinical relevance and utility. METHODS: A systematic review was conducted by a multidisciplinary team of researchers and clinicians (Prospero CRD42023402382). PubMed and Web of Science databases were searched using relevant keywords and inclusion/exclusion criteria. RESULTS: A total of 657 articles were initially identified, and after the selection process, 76 records were included for analysis comprising a total of 1293 patients with cerebral palsy. The quality assessment of the reviewed studies revealed a moderate overall quality, with deficiencies in sample size justification and participant information. Optoelectronic motion capture systems were predominantly used in the studies (N = 57/76). The population mainly consisted of individuals with spastic cerebral palsy (834/1293) with unilateral impairment (N = 1092/1293). Patients with severe functional impairment (MACS IV and V) were underrepresented with 3.4% of the 754 patients for whom the information was provided. Thirty-nine tasks were used across the articles. Most articles focused on unimanual activities (N = 66/76) and reach or reach and grasp (N = 51/76). Bimanual cooperative tasks only represented 3 tasks present in 4 articles. A total of 140 different parameters were identified across articles. Task duration was the most frequently used parameter and 23% of the parameters were used in only one article. CONCLUSION: Further research is necessary before incorporating quantified motion analysis into clinical practice. Existing protocols focus on extensively studied populations and rely on costly equipment, limiting their practicality. Standardized unimanual tasks provide limited insights into everyday arm use. Balancing methodological requirements and performance evaluation flexibility is a challenge. Exploring the correlation between outcome parameters and therapeutic guidance could facilitate the integration of quantified movement assessment into treatment pathways.

Retrospective study of functional benefits and satisfaction in multisite upper-limb surgery in children with unilateral cerebral palsy.

OBJECTIVES: To evaluate the functional impact of individualised multisite neuro-orthopedic upper-limb surgery in children with unilateral cerebral palsy, and to assess patient satisfaction. PATIENTS AND METHODS: This retrospective study evaluated the impact of surgery on unilateral functional capacity on the Melbourne Assessment (MA2) and Box and Blocks test, on bimanual performance on the Assisting Hand Assessment, and on achievement of individualised goals. Satisfaction was assessed on a Likert scale between 6 and 14 months after surgery. RESULTS: Twenty-three children were included (mean age, 13.2 ± 3 years). They underwent neuro-orthopedic surgery as part of their care pathway, with botulinum toxin, splints and functional training. After surgery, there was a significant 11.7-point improvement in the MA2 dexterity domain (p = 0.003) and 10.6 points in the MA2 range of motion domain (p = 0.005). Satisfaction was high in 81% of patients. CONCLUSION: Neuro-orthopedic upper-limb surgery included in a global care pathway in children with unilateral cerebral palsy improved unilateral upper-limb function and patient satisfaction. The present cohort should be expanded to further explore the impact of surgery on bimanual performance, focusing on more homogeneous functional levels and surgical procedures.

Early Intensive Bimanual Stimulation Program (BB-Bim) for Infants at Risk of Unilateral Cerebral Palsy: A Randomized, Multiple-Baseline, Single-Case Study.

IMPORTANCE: Clinical practice guidelines for infants at high risk of cerebral palsy (CP) emphasize the importance of very early and intensive intervention. OBJECTIVE: To determine the feasibility of a new, home-based, early intensive bimanual stimulation program (BB-Bim) and its impact on hand function in infants at risk of unilateral CP. DESIGN: Single case experimental design, multiple baseline across subjects, lasting from 12 to 15 wk, including a 4- to 7-wk randomized baseline, followed by 8 wk of BB-Bim. SETTING: Home. PARTICIPANTS: Infants (ages 3-12 mo) with suspected unilateral CP, whose parents agreed to participate in the stimulation program. INTERVENTION: Parent-provided bimanual stimulation 20 min/day, 6×/wk, with weekly occupational therapist coaching visits. MEASURES: Weekly repeated measures were the Hand Assessment in Infants (HAI) and Goal Attainment Scaling (GAS). Feasibility and relevance were assessed with a logbook and a parental report, including 10 continuous 0-10 scaled questions. RESULTS: Six infants were included (2 with left and 4 with right brain lesions). Parents provided a mean 3.4 to 6.2 stimulation sessions/wk. Feasibility and relevance were highly rated (Ms = 8.2-9.6, SDs = 0.2-1.3). Stimulation significantly improved HAI bimanual and total scores for all infants, with no impact on HAI unilateral scores. GAS scores improved with stimulation (significant for 3 infants). CONCLUSIONS AND RELEVANCE: BB-Bim was feasible and tended to improve bimanual function in infants at risk of unilateral CP. What This Article Adds: Parent-provided daily bimanual stimulation at home is feasible when parents are coached weekly by an occupational therapist. Bimanual stimulation seems to improve functional interactions between the hands among infants at high risk of unilateral CP.

Goal Attainment Scaling in rehabilitation: An educational review providing a comprehensive didactical tool box for implementing Goal Attainment Scaling.

CONTEXT: Goal Attainment Scaling (GAS) is a person-centered and collaborative approach, allowing to assess the effectiveness of an intervention on personally relevant goals. However, GAS is not a "scale" but a heterogeneous group of methodologies, including many variations and lack of consensus on high quality GAS. OBJECTIVE: The aim of this communication is to: 1. provide updated didactical information on GAS use in PRM practice and research; 2. increase awareness of GAS methodological challenges; 3. guide use of GAS as an integrated process of rehabilitation after goal setting and; 4. provide updated resources for self-directed learning and extensive supplemental material to increase knowledge and practical skills in GAS use. METHODS: Educational literature review about current GAS applications relevant to PRM fields. RESULTS: Practical advice is provided regarding clinical challenges in GAS: definition of 0 level, time-frame and means employed to attain the goal, dealing with unforeseen pattern of improvement, synthesizing the numerous significations of "SMART" goal acronym to guide best use of GAS, and thinking flexibility on the type of relevant goals that can be set. Challenges with GAS in rehabilitation research are presented in order to promote researcher's and reviewer's awareness on reliable use of GAS and encouraging best-use of GAS.

Does accelerometry reflect hand function in infants at risk of unilateral cerebral palsy? A secondary analysis of BB-Bim results.

BACKGROUND: Infants at high-risk of unilateral Cerebral Palsy (UCP) may have asymmetry in upper extremity movement and function, which should be identified as soon as possible for management. AIMS: To explore the feasibility of using two AX3 Axivity monitors in wrist-worn bracelets to quantify movements, and to identify whether accelerometry parameters are consistent with hand function. METHODS AND PROCEDURES: 6 infants at high risk of UCP (aged 3 to -12 months) were included in a Single-Case Experimental Design to explore the impact of an 8-week bimanual stimulation home program. OUTCOMES: Each week of the baseline (randomized duration 4-7 weeks) and 8-week program, the Hand Assessment for Infants (HAI) was performed and accelerometry parameters were collected during HAI and also during spontaneous activity, several times a week. RESULTS: Actimetry was analyzed during HAI and 238 spontaneous activity sessions (mean 42 ± 21 min). Actimetry ratios distribution and evolution show a high variability, especially for spontaneous activity. No strong correlation was found between HAI scores and accelerometry parameters, either collected during HAI, or during spontaneous activity times. CONCLUSION AND IMPLICATIONS: Despite its feasibility, using accelerometry bracelets looks unreliable for detecting and monitoring hand function in infants under one year.

VETCOSED study: efficacy of compressive garments for patients with hypermobile Ehlers-Danlos syndrome on shoulder stability and muscles strength.

PURPOSE: to assess the effect of wearing a compressive short-sleeve jacket on shoulder stability and rotator muscles in adult patients with a hypermobile subtype of Ehlers-Danlos syndrome. MATERIALS AND METHODS: a quasi-experimental study with "Pre/Post" design (4 weeks with versus 4 weeks without), open, conducted on a national cohort. Shoulder rotators were assessed with an isokinetic device at 180°/s and 90°/s; frequency of shoulder stability defects, pain (Visual Analogical Scale), and satisfaction (Quebec User Evaluation of Satisfaction with Assistive Technology) were reported. RESULTS: 36 patients (35 women), mean age 37.9 years, wore jackets for a meanly 7.8 h/day. >70% were satisfied with the effect on arthralgia, instability, or function. QUEST results were high (m = 4.1, SD = 0.7). After jacket wear, the power of external rotators at 180°/s was significantly increased (+1.29 W, CI95%: 0.31; 2.28; p = 0.0318). At 90°/s, no significant difference was found, either on power or strength. The on-off effect highlights a significant difference in external and internal rotators power, whatever the speed. The occurrence of subluxation (p = 0.0140) and dislocations (p = 0.0163) decreased. Pain decreased from 3.5/10 to 2.5/10, without significance (p = 0.0964). CONCLUSION: compressive CICATREX SED® jackets are well supported by patients, impact the power of external rotators at high speed (180°/s), and improve joint stability.IMPLICATIONS FOR REHABILITATIONCompressive garments made to measure are beneficial to patients with hypermobile Ehlers-Danlos syndrome.Compressive CICATREX SED® jackets clearly improve shoulder stability and help to promote muscle power in shoulder external rotators during high-speed movements.One month of jacket wearing seems to bring no lasting effect on shoulder-rotator power, so the jacket needs to be kept on for the benefits to be maintained.

Validity, reliability and responsiveness to change of the French version of the drooling impact scale.

BACKGROUND: work still needs to be done to measure the impact of sialorrhea on quality of life and define the efficacy of different therapies. The Drooling Impact Scale showed good validity and sensitivity to change, especially after botulinum toxin injection. The aim of this study is to present its French translation and to explore its validity, reliability and responsiveness to change in a group of children with Cerebral Palsy. METHODS: multicentre study at six rehabilitation centres in France. Children with Cerebral Palsy aged 4-18 years with sialorrhea problems were included (n = 55), either in a control group (n = 33) or in the intervention group (n = 22, with 3 drug treatment and 19 botulinum toxin injections). The French Drooling Impact Scale was administered twice, 1 month apart. RESULTS: The French Drooling Impact Scale total score at inclusion was meanly 53.9 (Standard Deviation 11.9) in the stable control group and 66.0 (16.1) in the intervention group (p = 0.0058). The validity of the scale was established, as well as an adequate internal consistency (Cronbach's α = 0.71); correlations between each item and the total score were found between 0.5 and 0.71 except for item 5 (r = 0.38) and item 7 (0.41). The test-retest reliability in stable children was good (Lin coefficient = 0.83, bias correction factor = 0.92 and Pearson correlation coefficient = 0.89). There was a high responsiveness to change, mean change was -40.0 in the intervention group and -3.6 in the stable group (p < 0.0001), with Standard Error of Measurement = 2.6. CONCLUSION: the French Drooling Impact Scale has shown sufficient clinometric properties to be used now by clinicians or researchers.IMPLICATIONS FOR REHABILITATIONThe Drooling Impact scale has now its French version.The French version of the Drooling Impact Scale has shown its validity and a good test-retest reliability.The responsiveness to change was explored in a group of children undergoing saliva-control interventions and the scale was able to show a big change.The authors recommend to use this questionnaire in a semi-directed interview conducted by a health professional.

Impact of an ergonomic seat on the stand-to-sit strategy in healthy subjects: Spinal and lower limbs kinematics.

PURPOSE: To assess differences in spinal, pelvic and lower limb parameters in healthy individuals during a stand-to-sit task using three different seating conditions. METHODS: Ten healthy adults carried out three stand-to-sit movements on different stools: a high ergonomic stool with the seat tilted 10° forward; a standard stool (adjusted to the same height as the ergonomic stool) and a standard stool at a lower level (so their thighs were horizontal). Movements were recorded by an optoelectronic Vicon system. RESULTS: Hip flexion was altered by the height of the seat (significantly greater for the low standard stool in comparison to either the ergonomic stool or the high standard stool (p < 0.0001)). There was also significantly less knee flexion with the ergonomic stool in comparison to the low standard stool (p < 0.0001) and to the high standard stool (p = 0.0017). Lumbar lordosis was not significantly altered by seat height, although it was less pronounced with the ergonomic stool, with a significantly higher range of motion for the pelvis (p = 0.015). At the thoracic level, no differences were observed, except that the stand-to-sit movement on the lower stool produced greater flexion. CONCLUSION: Lumbar lordosis was not increased by the ergonomic stool and the range of lower limb motion was reduced by the high seat. These findings contrast with current opinion that ergonomic seats promote lumbar lordosis.

Pain coping strategies in children with cerebral palsy.

AIM: To describe coping strategies in children and adolescents with cerebral palsy (CP), relative to age. METHOD: Patients were prospectively recruited from two paediatric rehabilitation centres in France. The Pediatric Pain Coping Inventory - French and Structured Pain Questionnaire were completed by an experienced professional for each child. RESULTS: One hundred and forty-two children with CP were included (80 males, 62 females; median age 12y; IQR=8-15y). They generally used fewer coping strategies than typically developing children ('Seeks social support and action': 12.47 vs 12.85, p=0.477; 'Cognitive self-instruction': 9.28 vs 10.90, p<0.001; 'Distraction': 4.89 vs 7.00, p<0.001; 'Problem solving': 4.43 vs 5.19, p<0.001). In the CP group, 'Seeks social support and action' decreased with age (p=0.021) and 'Cognitive self-instruction' increased with age (p<0.001). 'Problem solving' and 'Distraction' did not change with age. Coping strategies were influenced by Gross Motor Function Classification System level (p=0.022) and history of surgery (p=0.002). INTERPRETATION: Children with CP generally used fewer coping strategies than typically developing children and tended to rely on social support. Use of active strategies increased with age; however, they appeared later than in typically developing children and were used to a lesser extent. WHAT THIS PAPER ADDS: Children with cerebral palsy (CP) use fewer pain-coping strategies than typically developing children. Children with CP tend to use social support to cope with pain. Children with CP learn more appropriate strategies from previous painful experiences. Active coping strategies appear later but remain underused in children with CP.

ESTRATEGIAS DE AFRONTAMIENTO DEL DOLOR EN NIÑOS CON PARÁLISIS CEREBRAL: OBJETIVO: Describir estrategias de afrontamiento en niños y adolescentes con parálisis cerebral (PC), en relación con la edad. MÉTODO: Los pacientes fueron reclutados prospectivamente de dos centros de rehabilitación pediátrica en Francia. El Inventario de Afrontamiento del Dolor Pediátrico - Cuestionario de Dolor Francés y Estructurado fue completado por un profesional con experiencia para cada niño. RESULTADOS: Se incluyeron 142 niños con PC (80 varones, 62 mujeres; mediana de edad de 12 años; IQR = 8-15 años). En general, los niños con PC utilizaron menos estrategias de afrontamiento que los niños con desarrollo típico ("Busca apoyo social y acción": 12,47 vs 12,85, p = 0,477; "Autoinstrucción cognitiva": 9,28 vs 10,90, p <0,001; "Distracción": 4,89 vs 7,00, p <0,001; "Resolución de problemas": 4,43 vs 5,19, p <0,001). En el grupo de PC, la búsqueda de apoyo y acción social disminuyó con la edad (p = 0,021) y la autoinstrucción cognitiva aumentó con la edad (p <0,001). La "resolución de problemas" y la "distracción" no cambiaron con la edad. Las estrategias de afrontamiento se vieron influenciadas por el nivel del Sistema de Clasificación de la Función Motora Gruesa (p = 0,022) y los antecedentes quirúrgicos (p = 0,002). INTERPRETACIÓN: Los niños con PC generalmente usaron menos estrategias de afrontamiento que los niños con un desarrollo típico y tendían a confiar en el apoyo social. El uso de estrategias activas aumenta con la edad; sin embargo, aparecieron más tarde que en los niños con un desarrollo típico y se utilizaron en menor medida.

ESTRATÉGIAS PARA LIDAR COM A DOR EM CRIANÇAS COM PARALISIA CEREBRAL: OBJETIVO: Descrever estratégias para lidar com a dor em crianças e adolescentes com paralisia cerebral (PC), com relação à sua idade. MÉTODO: Pacientes foram prospectivamente recrutados em dois centros de reabilitação pediátrica na França. O Inventário Pediátrico de Manejo da Dor - Francês e o Questionário Estruturado sobre dor foram completados para cada criança por um profissional com experiência. RESULTADOS: Cento e quarenta e duas crianças com PC foram incluídas (80 do sexo masculino, 62 do sexo feminino; idade mediana 12a; IIQ=8-15a). Elas geralmente usaram menos estratégias para lidar com a dor do que crianças com desenvolvimento típico ('Procura suporte e ação social': 12,47 vs 12,85, p=0=,477; 'Auto-instrução cognitiva': 9,28 vs 10,90, p<0,001; 'Distração: 4,89 vs 7,00, p<0,001; 'Resolução do problema': 4,43 vs 5,19, p<0,001). No grupo com PC, 'Procura suporte e ação social' diminuiu com a idade (p=0,021) e Auto-instrução cognitiva' aumentou com a idade (p<0,001). 'Resolução de problemas' e 'Distração' não mudaram com a idade. As estratégias de manejo da dor foram influenciadas pelo nível do Sistema de Classificação da Função Motora Grossa (p=0,022) e histórico de cirurgia (p=0,002). INTERPRETAÇÃO: Crianças com PC geralmente usam menos estratégias para lidar com a dor do que crianças com desenvolvimento típico, e tendem a depender de suporte social. O uso de estratégias efetivas aumentou com a idade; no entanto, elas aparecem mais tarde do que em crianças com desenvolvimento típico, e são utilizadas em menor escala.

Development of a Pediatric Goal-Centered Upper Limb Spasticity Home Exercise Therapy Program for Use in a Phase-III Trial of Abobotulinumtoxina (Dysport®).

AIMS: To create a standardized home exercise therapy program that could be implemented by international sites to provide a consistent level of therapeutic intervention for pediatric patients participating in an ongoing Phase-III, randomized, controlled trial of repeat abobotulinumtoxinA injections for pediatric upper limb spasticity (NCT02106351). METHODS: Physical therapists, occupational therapists, and medical doctors worked collaboratively to design an exercise therapy program to be implemented in the home setting. In this article, we describe the development process and the finalized program that is currently being used in the Phase-III trial. RESULTS: The final program is presented as a "toolbox" for therapists, and includes a standardized step-wise process for choosing the most appropriate exercises and functional activities to achieve the agreed treatment goals of each abobotulinumtoxinA injection. The core toolbox includes: a clear protocol for clinicians, information sheets, signature of commitment forms, exercise score charts, and the library of exercises and functional activities that therapists choose from to aid the patient in achieving their treatment goals. CONCLUSIONS: Implementation of this home therapy program provides a standardized background of good practice against which to test the efficacy of abobotulinumtoxinA. Preliminary data show that the program is readily accepted by patients and their families.
