Validation of the Shriners Hospital for Children Upper Extremity Evaluation (SHUEE) for children with hemiplegic cerebral palsy

The effects of improvement in upper extremity function on gait and balance in children with upper extremity affected

BACKGROUND

This study aimed to investigate the effects of functional improvement in the upper extremity on gait and balance in children with upper extremity affected.

RESEARCH QUESTION

What are the effects of functional improvement in the upper extremity on gait and balance in children with upper extremity affected?

METHODS

Eighteen children with a diagnosis of rheumatologic diseases and 15 healthy children were evaluated with Shriners Hospital Upper Extremity Assessment, Jebsen-Taylor Hand Function Test, Abilhand Rheumatoid Arthritis Scale, 10-meter walk test and Childhood Health Assessment Questionnaire. For static balance assessment, the Biodex Balance was used. Ground reaction forces (peak forces (heel strike and push-off) and minimum force (loading response), single-limb support duration, Center-of-Force displacement and walking speed were evaluated with the Sensor Medica. Arm swing was evaluated with the Kinovea 2D motion analysis.

RESULTS

Before treatment, single-limb support duration and push-off force was higher and center-of-force displacement was lower on affected side compared to unaffected side in rheumatologic group. After the 6-week rehabilitation program, upper extremity function, quality of life and functional gait score improved. Single-limb support duration decreased on affected side and increased on unaffected side. On affected side, push-off force decreased. The arm swing parameters were similar before and after treatment.

SIGNIFICANCE

Improving upper extremity function can help with gait balance by decreasing the difference in walking and balance parameters between the affected and unaffected sides and providing for more symmetrical weight transfer.

A Pilot Feasibility Study on the Use of Dual-Joystick-Operated Ride-on Toys in Upper Extremity Rehabilitation for Children with Unilateral Cerebral Palsy

Children with unilateral cerebral palsy (UCP) require task-oriented practice several hours per week to produce meaningful gains in affected upper extremity (UE) motor function. Clinicians find it challenging to provide services at the required intensity and sustain child engagement. This pilot study assessed the acceptance and utility of a child-friendly program using dual-joystick-operated ride-on toys incorporated into an intensive UE rehabilitation camp. Eleven children with UCP between four and 10 years received ride-on-toy navigation training for 20-30 min/day, five days/week, for three weeks as part of camp programming. We report session adherence and percent time children spent in task-appropriate attention/engagement across sessions. The overall effects of camp programming on children's motor function were assessed using the Shriner's Hospital Upper Extremity Evaluation (SHUEE) from pretest to posttest and using training-specific measures of bimanual UE use and navigational accuracy. Children showed excellent adherence and sustained task-appropriate engagement across sessions. The combined program led to improved navigational accuracy (p-values ≤ 0.007) as well as spontaneous affected UE use during bimanual activities outside the training context (p < 0.001). Our pilot study provides promising evidence for using modified, commercially available ride-on toys to incentivize rehabilitation and boost repetitive, task-oriented UE practice among children with UCP.

Measuring functional hand use in children with unilateral cerebral palsy using accelerometry and machine learning

AIM

To investigate wearable sensors for measuring functional hand use in children with unilateral cerebral palsy (CP).

METHOD

Dual wrist-worn accelerometry data were collected from three females and seven males with unilateral CP (mean age = 10 years 2 months [SD 3 years]) while performing hand tasks during video-recorded play sessions. Video observers labelled instances of functional and non-functional hand use. Machine learning was compared to the conventional activity count approach for identifying unilateral hand movements as functional or non-functional. Correlation and agreement analyses compared the functional usage metrics derived from each method.

RESULTS

The best-performing machine learning approach had high precision and recall when trained on an individual basis (F1  = 0.896 [SD 0.043]). On an individual basis, the best-performing classifier showed a significant correlation (r = 0.990, p < 0.001) and strong agreement (bias = 0.57%, 95% confidence interval = -4.98 to 6.13) with video observations. When validated in a leave-one-subject-out scenario, performance decreased significantly (F1  = 0.584 [SD 0.076]). The activity count approach failed to detect significant differences in non-functional or functional hand activity and showed no significant correlation or agreement with the video observations.

INTERPRETATION

With further development, wearable accelerometry combined with machine learning may enable quantitative monitoring of everyday functional hand use in children with unilateral CP.

The upper limb in children with cerebral palsy. Evaluation and treatment

Management of the upper limb in children with cerebral palsy is often complex and must be carried out by a team experienced in this field. Several clinical parameters must be taken into consideration, such as higher functions, visual problems, overall upper limb function, motor control, sensitivity, presence of hemineglect or synkinesis, limb position at rest and during walking. And last but not least, a complete analysis of the upper limb is required. It is only after this exhaustive assessment - which often includes occupational therapy, physiotherapy and in some cases, video and electromyography evaluations - that a treatment indication can be discussed with the patient's family. Other than baseline treatment consisting of rehabilitation, occupational therapy and bracing, botulinum toxin injections could be an option, targeting specific muscle groups. Surgical treatments, which are often indicated in severe forms with contractures, are proposed after the patient's case is presented at a multidisciplinary meeting. These include selective neurotomy, muscle-tendon release, transfer or lengthening, and procedures on bone and joints (osteotomy, arthrodesis). LEVEL OF EVIDENCE: Expert opinion.

An Exploration of Tri-Axial Accelerometers in Assessing the Therapeutic Efficacy of Constraint-Induced Movement Therapy in Children with Unilateral Cerebral Palsy

This study aimed to elucidate the role of tri-axial accelerometers in assessing therapeutic interventions, specifically constraint-induced movement therapy (CIMT), in children with unilateral cerebral palsy (UCP). The primary focus was understanding the correlation between the actigraphy metrics recorded during CIMT sessions and the resultant therapeutic outcomes. Children with UCP, aged between 4 and 12 years, participated in this study from July 2021 to December 2022. In conjunction with in-clinic sessions, during which participants wore tri-axial accelerometers on both limbs, we analyzed actigraphy data over three days of routine activities pre- and post-CIMT. While not all metrics derived from the accelerometers indicated significant improvements post-intervention, there was a clear trend towards a more balanced usage of both limbs, particularly evident in Axis 3, associated with vertical movement (p = 0.017). Additionally, a discernible correlation was observed between changes in the magnitude ratio derived from actigraphy data during CIMT (Δweek3-week1) and variations in traditional assessments pre- and post-intervention (ΔT0-T1), specifically the Assisting Hand Assessment grasp and release. Using tri-axial accelerometers has helped clarify the potential impacts of CIMT on children with UCP. The preliminary results suggest a possible link between actigraphy metrics taken during CIMT and the subsequent therapeutic outcomes determined by standardized tests.

Expert consensus on the surgical evaluation and management of upper extremity spasticity in adults

In the last decade there has been incredible interest and advancement in the surgical care of adult patients with upper motor neuron (UMN) injuries. Spasticity represents a prevalent and debilitating feature of UMN syndrome, which can result from cerebral palsy, spinal cord injury, cerebrovascular accident and traumatic or anoxic brain injury. While several diagnostic tools and management strategies have been described for upper limb spasticity, evidence-based practice guidelines do not currently exist due to low patient volume and a paucity of surgeons routinely performing surgeries in UMN syndrome patients. As such, expert consensus may help provide guidance for patients, therapists and clinicians alike. In this article an expert panel was assembled, and the Delphi method was utilized to present diagnostic considerations, define operative indications, discuss surgical treatment modalities and encourage a standard set of outcome measures for patients with upper extremity spasticity.

Can the Shriners Hospital Upper Extremity Evaluation (SHUEE) Detect Change in Dynamic Position and Spontaneous Function of the Upper Limb in People With Hemiplegic Cerebral Palsy?

BACKGROUND

The Shriners Hospital Upper Extremity Evaluation (SHUEE) is a video-based measure designed to assess upper extremity function in people with cerebral palsy (CP). The SHUEE completes both dynamic positional analysis (DPA; position during functional activities) and spontaneous functional analysis (spontaneous use of the involved limb). Although the SHUEE has been suggested as a measure for planning upper limb interventions and evaluating outcomes, limited evidence of its ability to detect change exists. Thus, this study aimed to describe responsiveness of the SHUEE to detect change after orthopaedic surgery.

METHODS

In this Institutional Review Board-approved retrospective cohort study, we identified children with CP who were administered SHUEE on≥2 encounters. We formed pairs of initial and follow-up visits between temporally adjacent visits. Pairs were assigned to a surgery or non-surgery group based on intervening upper limb orthopaedic surgery. We compared differences in baseline SHUEE scores between groups and differences in temporally adjacent SHUEE scores within groups using Welch unequal variances t tests and paired t tests, respectively.

RESULTS

Nineteen people (7 female) with hemiplegic CP had≥2 SHUEE assessments; Manual Ability Classification System levels I (3), II (8), III (7), IV (1); Gross Motor Function Classification System levels I (10), II (7), IV (2); mean age at baseline 11.9 (5.1 to 19.1) years; and follow-up at 13.4 (5.5 to 19.7) years. Six people had≥2 visits leading to 14 surgical pairs and 10 non-surgical pairs. At baseline, DPA of the wrist and forearm were significantly lower in the surgical group ( P <0.05). At follow-up, no significant difference between the groups existed in DPA measures ( P >0.05). After surgical intervention, there was a significant change in overall and wrist DPA ( P <0.05).

CONCLUSIONS

The DPA measures demonstrated responsiveness to expected positional changes in the arm after orthopaedic surgery in people with CP. The SHUEE was useful in identifying abnormal segmental alignment pre-surgically and documenting changes in alignment postoperatively. As orthopaedic surgery does not address limb neglect or bimanual ability, spontaneous functional analysis scores were as expected-unchanged.

LEVEL OF EVIDENCE

Level III, retrospective cohort study.

The Use of Serious Gaming to Improve Sensorimotor Function and Motivation in People with Cerebral Palsy: A Systematic Review

The aim of this systematic review was to review the evidence for serious gaming interventions in improving sensorimotor function in children and adults with cerebral palsy (CP). Seven databases were searched with terms related to serious gaming and CP. Articles were evaluated according to the Downs and Black rating scale and important principles of serious gaming defined by Whyte et al. Extracted data included the population, intervention, serious gaming elements, outcomes, and authors' conclusions. Fifty-seven articles were identified for inclusion. Participants' ages ranged from 3 to 57 years. Interventions tested included commercial videogames as well as specially designed games. Most interventions had themed content, short-term goals, rewards, feedback, and multiple games. Outcome measures and study designs were inconsistent between studies. Sensorimotor function results of noncomparative studies were positive or neutral overall, but results of comparative studies were more mixed. We concluded that serious gaming interventions may be a useful adjunct to treatment as they are noninvasive, were not associated with deterioration in most cases, and may improve compliance. More comparative studies need to be completed to assess compliance and treatment outcomes. Future games should also aim to adhere more closely to the principles of serious gaming.

Surgical approach to forearm pronation deformity in patients with cerebral palsy: a systematic review

Background

Pronation deformity in patients with cerebral palsy can have a major impact on upper limb functionality. There is lack of consensus in the literature about the preferred surgical technique to address this deformity.

Study aim

To evaluate and synthesize the outcome of different surgical techniques for pronation deformity in patients with cerebral palsy.

Methodology

The databases MEDLINE and Embase were searched for publications up to December 2021. Articles were considered eligible for inclusion when the included patients had a pronation deformity caused by cerebral palsy and results of surgical intervention for pronation deformity were examined. Evaluation of the quality of the retrieved study was conducted using the MINORS tool. Meta-analysis was not possible due to the heterogeneity of interventions and reported outcomes.

Results

Nineteen studies, involving 475 patients and eight different techniques were included. All studies reported gain of active supination in most patients. The effect of surgery on functional gain was less clear and there was a large heterogeneity of reported functional outcome measures. There were 46 reported complications. Overall quality of study design was poor, illustrated by the average MINOR score of 6.9/16. Overall, there is a high risk of bias due to poor internal and external validity of the studies.

Conclusion

Despite positive reports on gain in supination and functionality after most procedures addressing pronation deformity in CP patients, no conclusions can be drawn concerning the preferred technique due to the low quality of the evidence.

Outcomes Associated with a Single Joystick-Operated Ride-on-Toy Navigation Training Incorporated into a Constraint-Induced Movement Therapy Program: A Pilot Feasibility Study

Our research aims to evaluate the utility of joystick-operated ride-on-toys (ROTs) as therapeutic adjuncts to improve upper extremity (UE) function in children with hemiplegic cerebral palsy (HCP). This study assessed changes in affected UE use and function following a three-week ROT navigation training incorporated into an existing constraint-induced movement therapy (CIMT) camp in 11 children (3-14 years old) with HCP. We report changes in scores on the standardized Shriners Hospital Upper Extremity Evaluation (SHUEE) from pretest-to-posttest and changes from early-to-late sessions in percent time spent by the affected arm in: (a) "moderate-to-vigorous activity", "light activity" and "no activity" bouts based on accelerometer data and (b) "independent", "assisted", and "no activity" bouts based on video data. We also explored relationships between standardized measures and training-specific measures of affected UE activity. We found small-to-medium improvements in the SHUEE scores. Between 90 and 100% of children also showed medium-to-large improvements in affected UE activity from early-to-late sessions using accelerometers and small improvements via video-based assessments. Exploratory analyses suggested trends for relationships between pretest-posttest and training-specific objective and subjective measures of arm use and function. Our pilot data suggest that single joystick-operated ROTs may serve as motivating, child-friendly tools that can augment conventional therapies such as CIMT to boost treatment dosing, promote affected UE movement practice during real-world navigation tasks, and ultimately improve functional outcomes in children with HCP.

A protocol for a single-arm interventional study assessing the effects of a home-based joystick-operated ride-on-toy navigation training programme to improve affected upper extremity function and spontaneous use in children with unilateral cerebral palsy (UCP)

INTRODUCTION

Children with unilateral cerebral palsy (UCP) face significant limitations in upper extremity (UE) function and require effective interventions that promote intensive goal-directed practice while maximising motivation and adherence with therapy. This study builds on our past work and will assess the effects of a 6-week researcher-caregiver codelivered, home-based ride-on-toy navigation training (RNT) programme in young children with UCP. We hypothesise that the RNT programme will be acceptable, feasible to implement, and lead to greater improvements in unimanual and bimanual function when combined with conventional therapy, compared with conventional therapy provided alone.

METHODS AND ANALYSIS

15 children with UCP between 3 and 8 years will be recruited. During the 6-week control phase, participants will receive treatement-as-usual alone. During the subsequent 6-week intervention phase, in addition to conventional therapy, RNT will be provided 4-5 times/week (2 times by researchers, 2-3 times by caregivers), 30-45 min/session. We will assess UE function using standardised tests (Quality of Upper Extremity Skills Test and Shriner's Hospital Upper Extremity Evaluation), reaching kinematics, wrist-worn accelerometry, caregiver-rated ABILHAND-Kids questionnaire, and training-specific measures of movement control during RNT. Programme feasibility and acceptance will be assessed using device use metrics, child and caregiver exit questionnaires, training-specific measures of child engagement, and the Physical Activity Enjoyment Scale. All assessments will be conducted at pretest, following the control phase (midpoint), and after completion of the intervention phase (post-test).

ETHICS AND DISSEMINATION

The study is approved by the Institutional Review Board of the University of Connecticut (# H22-0059). Results from this study will be disseminated through peer-reviewed manuscripts in scientific journals in the field, through national and international conferences, and through presentations to parent advocacy groups and other support organisations associated with CP.

Effects of stochastic resonance stimulation on manual function in children with hemiplegic cerebral palsy: A pilot clinical trial

OBJECTIVE

To investigate the effect of stochastic resonance stimulation (SRS) on manual abilities in children with hemiplegic cerebral palsy.

DESIGN

This pilot study is a randomized, sham-controlled, one-period, crossover trial.

SETTING

A neuroscience clinic with specialty therapy programs at an urban, university-based children's hospital.

PARTICIPANTS

Sixteen children ages 3 to 16 years who were diagnosed with hemiplegic cerebral palsy and had hand Manual Abilities Classification scale score of I to III with sufficient cognitive abilities to follow instructions.

INTERVENTIONS

Children donned wrist and arm bands that delivered SRS via embedded piezoelectric actuators in two randomly assigned conditions: sham (devices powered off) and subthreshold stimulation (SBT-SRS). Following the randomized protocol, a subset of participants also completed an open-label, above-threshold stimulation (AT-SRS) condition. Children carried out the same uni-manual and bimanual tasks during the randomized and open-label protocols; all data were collected in a single session.

MAIN OUTCOME MEASURE(S)

Box and Blocks (B&B) test, a uni-manual function test, and the Shriners Hospital Upper Extremity Evaluation (SHUEE). The SHUEE was video recorded and scored by two raters who were blinded to the experimental condition.

RESULTS

Thirteen children completed the B&B task and 14 children completed the SHUEE. Children in the SBT-SRS condition relative to sham condition moved an average of 1.8 more blocks in 1 minute (p = .08); scored an average of 3 points higher on SHUEE spontaneous functional analysis (p < .002); and scored an average of 2.7 points higher on SHUEE dynamic positional analysis (p = .20). In the open-label protocol, children in the AT-SRS condition relative to sham moved 3.9 more blocks than in the sham condition (n = 8, p < .001); scored an average of 4.5 points higher on SHUEE spontaneous functional analysis (n = 6, p = .08); and scored an average of 10.5 points higher on SHUEE dynamic positional analysis (n = 6, p = .01).

CONCLUSION(S)

In this pilot study, we found preliminary evidence that children with hemiplegic cerebral palsy demonstrated improved uni-manual abilities and increased function of the impaired hand on bimanual tasks when receiving a single session of SBT-SRS. Preliminary evidence also suggests that some children with hemiplegic cerebral palsy may improve more when receiving a single session of AT-SRS. Future research using larger, controlled studies should evaluate the optimal intensity, duration, and long-term effect of SRS for improving impaired manual abilities.

Dexterity of the Less Affected Hand in Children With Hemiplegic Cerebral Palsy

BACKGROUND

To determine if the "unaffected" hand in children with hemiplegic cerebral palsy (CP) is truly unaffected.

METHODS

We performed a retrospective review of manual dexterity as measured by the Functional Dexterity Test (FDT) in 66 children (39 boys, 27 girls, mean age: 11 years 4 months) with hemiplegic CP. Data were stratified by Manual Ability Classification System (MACS) level, birth weight, and gestational age at birth, and compared with previously published normative values.

RESULTS

The FDT speed of the less affected hand is significantly lower than typically developing (TD) children (P < .001). The development of dexterity is significantly lower than TD children (0.009 vs. 0.036 pegs/s/year, P < .001), with a deficit that increases with age. MACS score, birth weight, and age at gestation are not predictors of dexterity. The dexterity of the less affected hand is poorly correlated with that of the more affected hand.

CONCLUSIONS

Both dexterity and rate of fine motor skill acquisition in the less affected hand of children with hemiplegic CP is significantly less than that of TD children. The less affected hand should be evaluated and included in comprehensive treatment plans for these children.

Spatiotemporal parameters from instrumented motion analysis represent clinical measurement of upper limb function in children with cerebral palsy

BACKGROUND

There are various tools that measure upper limb function in children with cerebral palsy(CP) clinically, but these measurement methods are examiner-dependent and scale values are not proportional to the upper limb function which makes it difficult to quantify the function.

RESEARCH QUESTION

The purpose of this study was to investigate whether the new parameters derived from 3D motion analysis reflect the upper limb function which measured by Melbourne Assessment 2 (MA2) in children with cerebral palsy (CP) compared to the clinical measurements.

METHODS

Forty children with CP (24 boys, 16 girls; mean [SD] age, 6 years 11 months [3 years 5 months]) were recruited. Motion capture was conducted during phases T1-T4 of Reach and Grasp Cycles. New parameters (movement time, number of movement units, index of curvature) were derived from wrist marker data. Range of motion (ROM), accuracy, dexterity, and fluency of unilateral upper limb function were assessed using MA2. Spearman rank coefficients were determined to evaluate correlations between MA2 and the new parameters.

RESULTS AND SIGNIFICANCE

Index of curvature correlated negatively with MA2 accuracy scores during T1 (r_s -0.347, p < 0.05), T2 (r_s -0.471, p < 0.01), and T3 (r_s -0.660, p < 0.01). Number of movement units correlated negatively with MA2 ROM, accuracy, and fluency scores during T1 (ROM r_s -0.334; accuracy r_s -0.331; fluency r_s -0.375; p < 0.05) and T3 (ROM r_s -0.499; accuracy r_s -0.531; fluency r_s -0.515; p < 0.01). Index of curvature and number of movement units are objective, simple parameters showing fair to good correlation with MA2 accuracy and fluency of upper limb function.

Hand function development of children with hemiplegic cerebral palsy: A scoping review

PURPOSE

Hemiplegic cerebral palsy (hCP) typically impacts sensorimotor control of the hand, but comprehensive assessments of the hands of children with hCP are relatively rare. This scoping review summarizes the development of hand function for children with hCP.

METHODS

This scoping review focused on the development of hand function in children with hCP. Electronic databases (PubMed, PEDro, Web of Science, CINAHL, and SpringerLink) were searched to identify studies assessing hand function in children with hCP. The search was performed using keywords (e.g., "hemiplegia"). An iterative approach verified by two authors was used to select the studies. Articles which reported quantitative data for children with hCP on any items of a specified set of hand evaluations were included. Measures were sorted into three categories: quantitative neuromechanics, clinical assessments, and clinical functional evaluations.

RESULTS

Initial searches returned 1536 articles, 131 of which were included in the final review. Trends between assessment scores and age were examined for both hands.

CONCLUSION

While several studies have evaluated hand function in children with hCP, the majority relied on clinical scales, assessments, or qualitative descriptions. Further assessments of kinematics, kinetics, and muscle activation patterns are needed to identify the underlying impairment mechanisms that should be targeted for treatment.

Evaluation of a Customized 3D Printed ORGAN-Hand Orthotic Device for Unilateral Cerebral Palsy: a Pilot Study

To achieve intensive activity-based and goal-directed rehabilitation for unilateral cerebral palsy (UCP), several static and functional upper limb orthoses have been used but with limited robust evidence-base. The current pilot study evaluated the feasibility and efficacy of a customized 3D-printed orthotic device in children with UCP. The attainment of a prespecified goal and Shriners Hospital Upper Extremity Evaluation (SHUEE) at 3 and 6 mo were the efficacy measures. Of the 14 screened children, 5 (median age: 7.9 y; 3 boys) were included. The 3-mo follow-up could be completed for 3 children while 6-mo follow-up could be completed for 1 child. Rest could not be assessed due to pandemic restrictions. Although none attained set goals till the last follow-up, all 3 children (at 3-mo follow-up) showed improvement in SHUEE scores without any significant safety concerns. Further studies on 3D-printed orthosis in UCP are the need of the hour.

Validity and reliability of "Shriners Hospital for Children Upper Extremity Evaluation" in children with rheumatic diseases

INTRODUCTION/OBJECTIVES

The aim of this study was to investigate the validity and reliability of "Shriners Hospital for Children Upper Extremity Evaluation (SHUEE)" for children with rheumatic diseases.

METHODS

The study was carried out after obtaining the necessary permissions and retrospectively registered. The psychometric properties evaluated were reliability and concurrent validity. Reliability was determined by intra- and inter-observer agreement. Concurrent validity was performed using the Jebsen Taylor Hand Function Test (JTHFT), Abilhand-Rheumatoid Arthritis (Abilhand-RA), and Children Health Assessment Questionnaire (CHAQ). The validity and reliability of the evaluation were determined after the retest 1 week later.

RESULTS

Twenty children with rheumatic diseases were participated in to study. Intraclass coefficients ranged from 0.82 to 0.97 and the intraobserver reliability for SHUEE total and subscales were considered "excellent." Interobserver reliability was considered "excellent" for the SHUUE total score, spontaneous functional analysis and dynamic positional analysis, and "moderate" for grasp-release. A moderate negative correlation was determined between Spontaneous Functional Analysis and JTHFT (r =  - 0.63; p = 0.003).

CONCLUSION

SHUEE is a valid and reliable evaluation for children with rheumatic diseases. ClinicalTrials.org NCT04685434/21.12.2020 Key Points • SHUEE tends to be appropriate and acceptable to children with rheumatic diseases. • SHUEE can be used safely in the pediatric rheumatology group and it is beneficial in the clinical decision-making process. • SHUEE is a pioneering performance test that evaluates the quality of movement in pediatric rheumatology on a joint basis.

The design of Lil'Flo, a socially assistive robot for upper extremity motor assessment and rehabilitation in the community via telepresence

INTRODUCTION

We present Lil'Flo, a socially assistive robotic telerehabilitation system for deployment in the community. As shortages in rehabilitation professionals increase, especially in rural areas, there is a growing need to deliver care in the communities where patients live, work, learn, and play. Traditional telepresence, while useful, fails to deliver the rich interactions and data needed for motor rehabilitation and assessment.

METHODS

We designed Lil'Flo, targeted towards pediatric patients with cerebral palsy and brachial plexus injuries using results from prior usability studies. The system combines traditional telepresence and computer vision with a humanoid, who can play games with patients and guide them in a present and engaging way under the supervision of a remote clinician. We surveyed 13 rehabilitation clinicians in a virtual usability test to evaluate the system.

RESULTS

The system is more portable, extensible, and cheaper than our prior iteration, with an expressive humanoid. The virtual usability testing shows that clinicians believe Lil'Flo could be deployed in rural and elder care facilities and is more capable of remote stretching, strength building, and motor assessments than traditional video only telepresence.

CONCLUSIONS

Lil'Flo represents a novel approach to delivering rehabilitation care in the community while maintaining the clinician-patient connection.

The Dynamic Thumb-in-Palm Pattern in Children with Spastic Cerebral Palsy and Its Effects on Upper Limb Function

The thumb-in-palm (TIP) pattern is one of the most common upper limb deformities in cerebral palsy (CP). This study was designed to investigate the effect of the dynamic TIP pattern on upper limb function in children with spastic CP. This prospective observational study included a total of 106 children with CP with dynamic TIP. The House TIP classification while grasping small or large objects, Melbourne Assessment of Unilateral Upper Limb Function (MUUL), Shriners Hospital Upper Extremity Evaluation (SHUEE), Zancolli classification for wrist–finger flexor deformity, and degree of swan neck deformity were assessed. Type I was the most common and highest functioning House TIP classification type. However, there were no significant differences in upper arm function between types II, III, and IV. The three components of the SHUEE showed stronger association with MUUL than House TIP and Zancolli classifications. After multivariable analysis, functional use of the wrist–finger and the thumb played a more significant role than the dynamic alignment of the thumb. In conclusion, the House TIP classification is useful to describe the TIP pattern. The SHUEE thumb assessment is a useful tool for reflecting upper arm function. The upper arm function was related more with the associated wrist flexor deformity than dynamic TIP.

Unimanual Intensive Therapy with or without Unaffected Hand Containment in Children with Hemiplegia. A Randomized Controlled Pilot Study

Children with hemiplegia have lower spontaneous use and quality of movement in the affected upper limb. The modified constraint-induced movement therapy (mCIMT) is applied to improve the affected upper limb function. The objective of this study was to study the efficacy of unaffected hand containment to obtain changes in the function of the affected upper limb after applying two unimanual therapies. A randomized controlled pilot study was performed with 16 children diagnosed with congenital infantile hemiplegia, with eight children randomized in each group (average age: 5.54 years; SD: 1.55). mCIMT and unimanual therapy without containment (UTWC) were applied, with a total of 50 h distributed in five weeks (two h/per day). Two assessments were performed (pre- and post-treatment) to evaluate the affected upper limb spontaneous use, measured with the Shiners Hospital Upper Extremity Evaluation (SHUEE), and the quality of movement, measured with the Quality of Upper Extremity Skills Test (QUEST scale). The progression of the variables was different in both groups. The results are expressed in the median of the improvement percent and interquartile range (IQR). The spontaneous use analysis showed an improvement percent of 31.65 (IQR: 2.33, 110.42) in the mCIMT group with respect to 0.00 (IQR: 0.00, 0.00) in the UTWC group. The quality of movement increased in the mCIMT and UTWC groups, 24.21 (IQR: 13.44, 50.39), 1.34 (IQR: 0.00, 4.75), respectively and the greatest increase was obtained in the grasp variable for both groups. The use of unaffected hand containment in mCIMT would produce improvements in the affected upper limb functionality in children with hemiplegia (4-8 years old) compared to the same protocol without containment (UTWC).

Application of Low-Intensity Modified Constraint-Induced Movement Therapy to Improve the Affected Upper Limb Functionality in Infantile Hemiplegia with Moderate Manual Ability: Case Series

OBJECTIVE

To assess the functionality of the affected upper limb in children diagnosed with hemiplegia aged between 4 and 8 years after applying low-intensity modified Constraint-Induced Movement Therapy (mCIMT).

METHODS

Prospective case series study. A mCIMT protocol was applied for five weeks, with two hours of containment per day. The study variables were quality of movement of the upper limb, spontaneous use, participation of the affected upper limb in activities of daily living, dynamic joint position, grasp-release action, grasp strength, supination and extension elbow movements. Four measurements were performed, using the quality of upper extremity test (QUEST) scale, the Shriners Hospital for Children Upper Extremity Evaluation (SHUEE) Evaluation, a hand dynamometer and a goniometer.

RESULTS

The sample was composed of eight children with moderate manual ability. Statistically significant differences were detected in all the studied variables (p < 0.05) between the pre-treatment and post-treatment results (Week 0-Week 5), except for upper limb dressing, putting on splints and buttoning up. In the first week, the changes were statistically significant, except for protective extension, grasp strength, grasp-release and all functional variables (level of functionality and participation of the patient's upper limbs) in the SHUEE Evaluation (p > 0.05). The greatest increase occurred in spontaneous use from Assessment 1 to Assessment 4 (p = 0.01), reaching 88.87% active participation in bimanual tasks. The quality of movement of the upper limb exhibited a significant value due to the increase in dissociated movements and grasp (p = 0.01).

CONCLUSION

A low dose (50 h) of mCIMT increased the functionality of children diagnosed with congenital hemiplegia between 4 and 8 years of age with moderate manual ability.

BRAZILIAN VERSION OF THE SHRINERS HOSPITAL UPPER EXTREMITY EVALUATION (SHUEE): TRANSLATION, CULTURAL ADAPTATION, AND EVALUATION OF PSYCHOMETRIC PROPERTIES

Objective:

To validate the upper limb assessments tool, Shriners Hospital Upper Extremity Evaluation (SHUEE), for individuals with hemiplegic cerebral palsy in the Brazilian population.

Methods:

Validation study to translate and culturally adapt the Manual and the instrument. The psychometric properties evaluated were reliability and convergent validity. Reliability was determined by internal consistency (Cronbach’s α coefficient), ceiling and floor effect, sensitivity to changes, and intra- and interobserver agreement. Convergent validity was performed using the Pediatric Motor Activity Log, the self-care scale of the Pediatric Evaluation of Disability Inventory, and the Manual Ability Classification System.

Results:

We evaluated 21 individuals with hemiplegic cerebral palsy, with a mean age of 8.7±4.0 years. After the instrument was translated, there was no need for cultural adaptation. The total Cronbach’s α coefficient was 0.887 (95% confidence interval [95%CI] 0.745-0.970). We calculated sensitivity to changes in five subjects who underwent treatment with Botulinum Toxin Type A and physical therapy, with a significant difference between pre- and post-treatment evaluations in the Spontaneous Functional Analysis and Dynamic Positional Analysis. Convergent validity showed a significant correlation of the Spontaneous Functional Analysis and Dynamic Positional Analysis with the scales evaluated. All items of SHUEE presented high intra- and interobserver agreement.

Conclusions:

The results revealed that the Brazilian version of the SHUEE demonstrated good reliability and convergent validity, suggesting that it is an adequate and reliable tool for individuals with hemiplegic cerebral palsy in the Brazilian population.

Effects of upper extremity surgery on activities and participation of children with cerebral palsy: a systematic review

AIM

To evaluate and synthesize the evidence for effects of upper extremity surgery (UES) on activities and participation of children and adolescents with cerebral palsy (CP).

METHOD

The databases MEDLINE, Embase, and PsycINFO were searched for publications up to September 2018. Studies included were comparative studies with or without concurrent comparison groups or case series with pretest/posttest outcomes with a minimal sample size of 10 participants; those that reported the effects of UES with a follow-up time of at least 5 months; those including patients diagnosed with CP aged up to 20 years; and those that used a validated activity-based instrument. Risk of bias was assessed using the ROBINS-I (Risk Of Bias In Non-randomised Studies - of Interventions) tool and quality assessment was performed using the Grading of Recommendations Assessment, Development and Evaluation.

RESULTS

Twelve studies, involving 310 children and adolescents, were included. The ability and perception of the patient to use the hand(s) and perform activities (measured with the Shriners Hospital Upper Extremity Evaluation, Assisting Hand Assessment, and House Functional Classification) improved significantly after UES. The quality of evidence was very low for each of the activity outcomes of interest.

INTERPRETATION

The very low evidence prohibits recommendations on the use of UES to guide clinical practice. More high-quality comparative studies are needed to obtain better insight into the effects of UES on activities and participation.

WHAT THIS PAPER ADDS

Low quality of evidence for effects of upper extremity surgery (UES) on activities and participation. Limited evidence for improvement in activities and participation after UES.

Portable Motion-Analysis Device for Upper-Limb Research, Assessment, and Rehabilitation in Non-Laboratory Settings

This study presents the design and feasibility testing of an interactive portable motion-analysis device for the assessment of upper-limb motor functions in clinical and home settings. The device engages subjects to perform tasks that imitate activities of daily living, e.g. drinking from a cup and moving other complex objects. Sitting at a magnetic table subjects hold a 3D printed cup with an adjustable magnet and move this cup on the table to targets that can be drawn on the table surface. A ball rolling inside the cup can enhance the task challenge by introducing additional dynamics. A single video camera with a portable computer tracks real-time kinematics of the cup and the rolling ball using a custom-developed, color-based computer-vision algorithm. Preliminary verification with marker-based 3D-motion capture demonstrated that the device produces accurate kinematic measurements. Based on the real-time 2D cup coordinates, audio-visual feedback about performance can be delivered to increase motivation. The feasibility of using this device in clinical diagnostics is demonstrated on 2 neurotypical children and also 3 children with upper-extremity impairments in the hospital, where conventional motion-analysis systems are difficult to use. The device meets key needs for clinical practice: 1) a portable solution for quantitative motor assessment for upper-limb movement disorders at non-laboratory clinical settings, 2) a low-cost rehabilitation device that can increase the volume of in-home physical therapy, and 3) the device affords testing and training a variety of motor tasks inspired by daily challenges to enhance self-confidence to participate in day-to-day activities.

Inter- and Intrarater Reliability of the Thumb Grasp and Pinch Assessment for Children Following Index Pollicization for Congenital Thumb Hypoplasia

PURPOSE

The Thumb Grasp and Pinch (T-GAP) assessment quantifies functional hand use in children with congenital thumb hypoplasia by categorizing grasp and thumb use patterns during assessment activities that encourage a variety of grasp and pinch styles. This study aims to demonstrate interrater and intrarater reliability results of the T-GAP.

METHODS

A retrospective review was performed of children who had undergone index finger pollicization for congenital thumb hypoplasia and subsequent evaluation with videotaping of the T-GAP assessment. Following a training period, 4 occupational therapists scored 11 T-GAP videos on 2 separate occasions, separated by at least 2 weeks. Intraclass correlation coefficients (ICCs), standard error of measurements, minimum detectable change (MDC), and Pearson correlation coefficients were calculated.

RESULTS

The T-GAP raw scores were 16 to 55, demonstrating a range of mild to severe hand grasp differences. The ICCs for the interrater reliability trials were 0.887 and 0.901. Intrarater ICCs were all above 0.88. The MDC for each trial was 8.1 and 6.7 points. Pearson correlation coefficients calculated for each rater and each pair of raters were above 0.8 in all cases.

CONCLUSIONS

Interrater and intrarater reliability testing results for the T-GAP were excellent in all cases; this strongly suggests that results from T-GAP assessments are reliable. The high ICCs suggest that raters can classify and score children's hand function consistently.

CLINICAL RELEVANCE

This study, in conjunction with previous work, suggests that the T-GAP may be an ideal approach to assessing the outcomes of pollicization and provide a means of ongoing assessment of children's grip and pinch function.

The Cerebral Palsy Profile of Health and Function: Upper-Extremity Domain's Sensitivity to Change Following Musculoskeletal Surgery

PURPOSE

The Cerebral Palsy Profile of Health and Function (CP-PRO) Computerized Adaptive Tests (CAT) are quality of life measures developed specifically for use in children with cerebral palsy. This study examined the ability of the upper-extremity (UE) CP-PRO CAT to detect change in function after UE surgery compared with the Pediatric Outcomes Data Collection Instrument (PODCI), ABILHAND-Kids, and Box and Blocks test.

METHODS

From 2009 to 2013, children with cerebral palsy who had UE musculoskeletal surgery completed the UE CP-PRO CAT, PODCI-UE, ABILHAND-Kids, and Box and Blocks tests before surgery (97 children) and at 3 postoperative intervals: 6 months (80 children), 12 months (73 children), and 24 months (52 children). Mean, SD, effect size (ES), and standardized response mean (SRM) values for each measure at each time interval and each level of the Manual Ability Classification System were calculated and compared. Finally, the minimal detectable change at the 90% confidence level was determined.

RESULTS

Values for the ES (0.40) and SRM (0.53) for the UE CP-PRO CAT at baseline to 6 months were moderate and significantly greater than the PODCI-UE (ES, 0.18; SRM, 0.25). The ES and SRM for the PODCI-UE, ABILHAND-Kids, and Box and Blocks tests were not significantly greater than for the UE CP-PRO CAT at any period. From baseline to 6 months, the UE CP-PRO CAT detected a large and significant improvement for Manual Ability Classification System level II (SRM, 0.70; ES, 0.70). The minimal detectable change for the UE CP-PRO CAT was 5.20.

CONCLUSIONS

The UE CP-PRO CAT is significantly better in detecting change in UE function in the first 6 months after surgery and is comparable to other measures at 12 and 24 months.

Constraint-induced movement therapy in children with unilateral cerebral palsy

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.

Actigraph assessment for measuring upper limb activity in unilateral cerebral palsy

BACKGROUND

Detecting differences in upper limb use in children with unilateral cerebral palsy (UCP) is challenging and highly dependent on examiner experience. The recent introduction of technologies in the clinical environment, and in particular the use of wearable sensors, can provide quantitative measurement to overcome this issue. This study aims to evaluate ActiGraph GT3X+ as a tool for measuring asymmetry in the use of the two upper limbs (ULs) during the assessment with a standardized clinical tool, the Assisting Hand Assessment (AHA) in UCP patients aged 3-25 years compared to age-matched typically developing (TD) subjects.

METHODS

Fifty children with UCP and 50 TD subjects were assessed with AHA while wearing ActiGraphs GT3X+ on both wrists. The mean activity of each hand (dominant and non-dominant, MADH and MANDH, respectively) and the asymmetry index (AI) were calculated. Two linear mixed model analyses were carried out to evaluate how dependent actigraphic variables (i.e. MANDH and AI) varied by group (TD vs UCP) and among levels of manual ability based on Manual Ability Classification System (MACS). In both models age, sex, side of hemiplegia, presence/absence of mirror movements were specified as random effects.

RESULTS

The MANDH was significantly lower in UCP compared to TD, while the AI was significantly higher in UCP compared to TD. Moreover, in UCP group there were significant differences related to MACS levels, both for MANDH and AI. None of the random variables (i.e. age, sex, side, presence/absence of mirror movements) showed significant interaction with MANDH and AI.

CONCLUSIONS

These results confirm that actigraphy could provide, in a standardized setting, a quantitative description of differences between upper limbs activity.

Duruöz Hand Index: Is it valid and reliable in children with unilateral cerebral palsy?

PURPOSE

To investigate the validity and reliability of the Duruöz Hand Index (DHI) in patients with unilateral cerebral palsy (CP).

METHODS

Assessments of patients (n = 23) were performed using the Modified Ashworth Scale (MAS), the Manual Ability Classification System (MACS), the grip and pinch strength tests, and DHI. Following the data collection, retest of DHI was administered telephonically within a 2-week period.

RESULTS

Test-retest reliability and internal consistency of DHI were found to be excellent with a Cronbach's alpha value of 0.93 and an intraclass correlation coefficient value of 0.94. The correlation between the DHI and MACS was detected significantly high (r = 0.840, p = < 0.010). The DHI also correlated with grip and pinch strength in the affected side (r = -0.459, p = < 0.050; r = -0.509, p = < 0.050).

CONCLUSIONS

DHI is a valid and reliable questionnaire for patients with unilateral CP.

An Assessment of the Applicability of Shriners Hospital Upper Extremity Evaluation as a Decision-making Tool and Outcome Measure in Upper Limb Cerebral Palsy in Indian Children

BACKGROUND

The aim of this study was to assess the applicability and performance of the Shriners Hospital Upper Extremity Evaluation (SHUEE) and to determine its usefulness in clinical decision-making and as an outcome measure with reference to Indian children suffering from cerebral palsy.

MATERIALS AND METHODS

The SHUEE videos of 40 children with cerebral palsy with spastic hemiplegia or asymmetrical diplegia were analyzed and scored. Seven children had undergone upper extremity surgery based on a preoperative evaluation. All seven had a postoperative evaluation. Pre- and postoperative scores were compared. Intra- and interobserver reliability was assessed. The level of familiarity and comfort of the children with the assigned tasks was gauged.

RESULTS

Analysis of the scores revealed that patients could be categorized into three discrete groups based on the modified House scores and Spontaneous Functional Analysis (SFA) scores, which helps in identifying the patients who would benefit from surgical intervention. In the seven children who were operated, there was a mean increase in the postoperative SFA (2.97, P = 0.259), Dynamic Positional Analysis (3.15, P = 0.229) and Grasp/Release Analysis (4.96, P = 0.334) scores, though the differences were not statistically significant. There was excellent intraobserver (r - 0.98) and interobserver reliability (r - 0.97, 0.96) based on the intraclass correlation coefficient. The children were familiar with the assigned tasks and were not duly uncomfortable while attempting to perform them.

CONCLUSIONS

SHUEE is a useful modality to assess upper limb function in Indian children with cerebral palsy, and can be used as a decision-making tool and mode of documentation.

Assessment of the Spastic Upper Limb with Computational Motion Analysis

This article presents the current status of integrating 3-dimensional motion analysis and electromyography to assess upper extremity function clinically. The authors used their approach to establish a normative database for 5 Shriners Hospital Upper Extremity Evaluation tasks, which provides ranges of motion at the point of task achievement. Also, the inter-joint correlations are provided to understand the movement coordination required for each task. Distal upper extremity motion is strongly related to proximal function, supporting the idea that treatment of the proximal upper extremity deficits may be best preceded by treatment of the more distal upper extremity segments.

Surgical Management of Spasticity of the Shoulder

Although spastic conditions often involve the shoulder, it is rare for surgical intervention to be required. In cases in which chemodenervation and therapy are insufficient to optimize the patient's function or minimize their care requirements, surgical options, such as tendon and joint releases, can be considered. Tendon transfers are rarely indicated. Nerve transfers, particularly contralateral C7, may play a larger role in the future as we gain further understanding into the risks, indications, and contraindications of this exciting technique.

Outcomes After Surgical Treatment of Spastic Upper Extremity Conditions

Surgical interventions for the spastic upper extremity aim to correct the common deformities of elbow flexion, forearm pronation, wrist flexion and ulnar deviation, and thumb-in-palm deformity. One goal is achieving optimal function and improved limb positioning. Aesthetics of the limb have a profound impact on self-esteem and satisfaction. Surgical deformity correction has not reliably been shown to improve sensory function such as stereognosis. Validated outcome measures are used to present outcomes after surgical treatment of the spastic upper extremity as it relates to motor function and limb positioning, sensory function, and self-esteem.

The validity and reliability of the Test of Arm Selective Control for children with cerebral palsy: a prospective cross-sectional study

AIM

This study examined the reliability and validity of the Test of Arm Selective Control (TASC) to examine upper extremity selective voluntary motor control in children and adolescents with all types of spastic cerebral palsy (CP).

METHOD

Fifty-six participants with CP, ranging in age from 5 years 9 months to 18 years 11 months (average 11y 7mo, SD 3y 9mo; 25 males, 31 females), participated in this prospective cross-sectional study. They were evaluated using the TASC and several clinical measures.

RESULTS

TASC and Manual Ability Classification System (r=-0.529, p<0.001), TASC and ABILHAND-Kids (r=0.596, p<0.001), and TASC and affected extremities (r=-0.486, p=0.001) were moderately correlated. There was a weak correlation between the TASC and Gross Motor Function Classification System (r=-0.363, p=0.006) and no correlation between the TASC and age (p=0.366) or rater (p=0.713). Interrater reliability for upper extremity total score (intraclass correlation coefficient [ICC]=0.92-0.94) and upper extremity limb scores (ICC=0.92-0.96) was high for two independent rater groups (p≤0.001). Average time to administer was 16 minutes, 18 seconds.

INTERPRETATION

The TASC is a reliable and valid tool for objective assessment of selective voluntary motor control. Clinically this measure may guide the selection of medical, surgical, or therapy interventions and may improve outcome prognosis.

WHAT THIS PAPER ADDS

The Test of Arm Selective Control (TASC) demonstrates a high degree of reliability and multiple aspects of validity when assessing upper extremity selective control in those with cerebral palsy. The TASC is an upper limb companion to the Selective Control Assessment of the Lower Extremity.

Adductor Tenotomy Combined with Palmar Capsulodesis for Spastic Thumb-in-Palm Deformity in Cerebral Palsy: Description of a Surgical Technique and Clinical Results

BACKGROUND

Spastic thumb deformity in cerebral palsy significantly impedes hand function. Flexion-adduction forces across the first ray is the result from imbalance between intrinsic and extrinsic muscles. Multiples surgeries have been devised for the treatment of this condition such as contracture release and by tendon transfers for balancing the muscles forces. We report the results of a less demanding surgical technique, intended to avoid hyperextension of the metacarpophalangeal joint previously described in other series.

METHODS

Five patients with cerebral palsy who underwent a surgical correction for their thumb-in-palm deformity between January 2013 and August 2014 were included. All patients were assessed postoperatively with a minimum follow up of six months. Three criteria were chosen to evaluate functional ability: capacity to perform pinch, volitional muscle control and usefulness of the hand in daily life activities.

RESULTS

Patients who had surgery for spastic thumb deformity were reviewed. The thumb was maintained out of the palm in all patients. Three patients were able to perform correct pinch, achieved volitional muscle control and a more functional hand. One patient had limitation to achieve one of the evaluated daily life activities and one patient lacked active thumb movement for pinch, motor control and achieved no daily life activities. No postoperative complications were recorded.

CONCLUSIONS

We present a less challenging technique that should be taken into account for the treatment of thumb-in-palm deformity. Appearance and functional improvement can be achieved with this surgical procedure avoiding disadvantages of secondary deformities.

Assessment of Upper Limb Motor Dysfunction for Children with Cerebral Palsy Based on Muscle Synergy Analysis

Muscle synergies are considered to be building blocks underlying motor behaviors. The goal of this study is to explore an objective and effective method to assess the upper limb motor dysfunction of cerebral palsy (CP) children from the aspect of muscle synergy analysis. Fourteen CP children and 10 typically developed (TD) children were recruited to perform three similar upper limb motion tasks related to the movements of elbow and shoulder joints, and surface electromyographic (sEMG) signals were recorded from 10 upper arm and shoulder muscles involved in the defined tasks. Non-negative matrix factorization algorithm was used to extract muscle synergies and the corresponding activation patterns during three similar tasks. For each subject in TD group, four muscle synergies were extracted in each task. Whereas, fewer mature synergies were recruited in CP group, and many abnormal synergy structures specific to CP group appeared. In view of neuromuscular control strategy differences, three synergy-related parameters were proposed and synergy structure similarity coefficient was found to have high ability in depicting the inter-subject similarity within task and the intra-subject similarity between tasks. Seven upper limb assessment (UPA) metrics, which were defined as the combinations of synergy structure similarity coefficients of three tasks, were proposed to assess the upper limb motor function of CP children. The experimental results demonstrated that these UPA metrics were able to assess upper limb motor function comprehensively and effectively. The proposed assessment method can serve as a promising approach to quantify the abnormality of muscle synergies, thus offering potential to derive a physiologically based quantitative index for assessing upper limb motor function in CP clinical diagnosis and rehabilitation.

Orthopedic surgery in cerebral palsy: Instructional course lecture

Orthopedic surgery (OS) plays an important role in the management of cerebral palsy (CP). The objectives of OS are to optimize functions and prevent deformity. Newer developments in OS for CP include emphasis on hip surveillance, minimally invasive procedures, use of external fixators instead of plates and screws, better understanding of lever arm dysfunctions (that can only be corrected by bony OS), orthopedic selective spasticity-control surgery, and single-event multilevel lever arm restoration and anti spasticity surgery, which have led to significant improvements in gross motor function and ambulation, especially in spastic quadriplegia, athetosis, and dystonia. The results of OS can be dramatic and life altering for the person with CP and their caregivers if it is performed meticulously by a specialized surgical team, at the appropriate age, for the correct indications, employing sound biomechanical principles and is followed by physician-led, protocol based, intensive, multidisciplinary, institutional rehabilitation, and long term followup. However, OS can be a double-edged sword, and if performed less than optimally, and without the supporting multidisciplinary medical and rehabilitation team, expertise and infrastructure, it often leads to significant functional worsening of the person with CP, including irretrievable loss of previous ambulatory capacity. OS must be integrated into the long term management of the person with CP and should be anticipated and planned at the optimal time and not viewed as a "last resort" intervention or failure of rehabilitation. This instructional course lecture reviews the relevant contemporary principles and techniques of OS in CP.

Video-assisted functional assessment of index pollicisation in congenital anomalies

PURPOSE

Functional results of index pollicisation are usually assessed by the clinical score of Percival. This score is based on elementary hand movements and does not reflect the function of the neo thumb in daily life activities. The aim of this study was to develop a new video-assisted scoring system based on daily life activities to assess index pollicisation functional outcomes.

METHODS

Twenty-two consecutive children, operated between 1998 and 2012, were examined with a mean of 77 months after surgery. The mean age at surgery was 34 months. Post-operative results were evaluated by a new video-assisted 14-point scoring system consisting of seven basic tasks that are frequently used in daily activities. The series of tasks was performed both on the request of the examiner and in real-life conditions with the use of a hidden camera. Each video recording was examined by three different examiners. Each examiner rated the video recordings three times, with an interval of one week between examinations. Inter- and intra-observer agreements were calculated.

RESULTS

Inter- and intra-observer agreements were excellent both on request (κ = 0.87 [0.84-0.97] for inter-observer agreement and 0.92 [0.82-0.98] for intra-observer agreement) and on hidden camera (κ = 0.83 [0.78-0.91] for inter-observer agreement and 0.89 [0.83-0.96] for intra-observer agreement). The results were significantly better on request than on hidden camera (p = 0.045). The correlation between the video-assisted scoring system and the Percival score was poor.

CONCLUSION

The video-assisted scoring system is a reliable tool to assess index pollicisation functional outcomes. The scoring system on hidden camera is more representative of the neo thumb use in daily life complex movements.

Selective Control of the Upper Extremity Scale: validation of a clinical assessment tool for children with hemiplegic cerebral palsy

AIM

The ability to determine the relationship between selective motor control and upper extremity function in children with unilateral cerebral palsy (CP), and to measure the functional outcome and efficacy of interventions designed to improve selective motor control, has been limited by the lack of an objective, validated tool. The primary objective of this study is to describe the development of a clinical tool entitled Selective Control of the Upper Extremity Scale (SCUES), and present evidence of its validity and reliability.

METHOD

Content validity was established through an expert panel (eight clinicians, mean and median of 17y of clinical experience, range 2-30y). Intra- and interrater reliability was determined by six occupational therapists who scored 10 participant studies. Construct validity of the SCUES was established by comparison to the spontaneous functional analysis section of the Shriners Hospitals Upper Extremity Evaluation, the Manual Ability Classification System, and the Box and Block test for 25 children with unilateral CP.

RESULTS

The content validity ratio values were greater than 0 (indicating >50% agreement) for 33 of the 34 items (97%), and equal or greater than 0.5 (indicating ≥75% agreement) for 26 of the 34 items (76%). Intrarater reliability was excellent (intraclass correlation coefficient [ICC] >0.75) for all segments and joints of the affected extremity. Interrater reliability was excellent for all segments and joints of the affected extremity except the shoulder (ICC=0.72). The SCUES was strongly correlated with the SHUEE (Spearman's rho=0.69, p=0.003). The SCUES was not correlated with the Manual Ability Classification System (rho=-0.24, p=0.369) or the Box and Block test (rho=0.47, p=0.066).

INTERPRETATION

Psychometric analysis of the SCUES revealed comparable validity to other accepted video-based clinical assessment tools for the upper extremity in children with CP.

A systematic review of evidence-based assessment practices by allied health practitioners for children with cerebral palsy

AIM

The routine use of psychometrically robust assessment tools is integral to best practice. This systematic review aims to determine the extent to which evidence-based assessment tools were used by allied health practitioners for children with cerebral palsy (CP).

METHOD

The Preferred Reporting Items for Systematic Reviews and Meta-Analysis protocols 2015 was employed. A search strategy applied the free text terms: 'allied health practitioner', 'assessment', and 'cerebral palsy', and related subject headings to seven databases. Included articles reported assessment practices of occupational therapists, physiotherapists, or speech pathologists working with children with CP aged 0 to 18 years, published from the year 2000.

RESULTS

Fourteen articles met the inclusion criteria. Eighty-eight assessment tools were reported, of which 23 were in high use. Of these, three tools focused on gross motor function and had acceptable validity for use with children with CP: Gross Motor Function Measure, Gross Motor Function Classification System, and goniometry. Validated tools to assess other activity components, participation, quality of life, and pain were used infrequently or not at all.

INTERPRETATION

Allied health practitioners used only a few of the available evidence-based assessment tools. Assessment findings in many areas considered important by children and families were rarely documented using validated assessment tools.

Grading and Quantification of Upper Extremity Function in Children with Spasticity

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.

Establishing expert consensus on the evaluation of pediatric upper extremity function

STUDY DESIGN

Consensus statement.

INTRODUCTION

There is a lack of consensus in the literature on the measures of pediatric upper extremity (UE) function for musculoskeletal conditions.

PURPOSE

To establish expert consensus on utility, satisfaction and importance of functional outcome measures in children with UE musculoskeletal conditions, across International Classification of Functioning, Disability and Health (ICF) domains.

METHODS

Using Delphi Consensus Methodology, expert panelists completed three rounds of questionnaires.

RESULTS

Agreement on Body Functions and Structure, Activity, and Participation outcome measures was determined (α, ICC range = 0.86-0.96). Mean satisfaction of measures in the respective domains was between 6.93 and 7.94. The Activity domain had lowest satisfaction, however there was consensus it was the most important.

DISCUSSION

Consensus on relative importance, but low satisfaction in the Activity domain suggests a need for better outcomes in this domain.

CONCLUSIONS

Examination of the torque required to passively palmar abduct the thumb CMC joint in a pediatric population with hemiplegia and stroke

Many activities of daily living involve precision grasping and bimanual manipulation, such as putting toothpaste on a toothbrush or feeding oneself. However, children afflicted by stroke, cerebral palsy, or traumatic brain injury may have lost or never had the ability to actively and accurately control the thumb. To translate insights from adult rehabilitation robotics to innovative therapies for hand rehabilitation in pediatric care, specifically for thumb deformities, an understanding of the torque needed to abduct the thumb to assist grasping tasks is required. Participants (n=16, 10 female, 13.2±3.1 years) had an upper extremity evaluation and measures were made of their passive range of motion, anthropometrics, and torques to abduct the thumb for both their affected and non-affected sides. Torque measures were made using a custom wrist orthosis that was adjusted for each participant. The torque to achieve maximum abduction was 1.47±0.61inlb for the non-affected side and 1.51±0.68inlb for the affected side, with a maximum recorded value of 4.87inlb. The overall maximum applied torque was observed during adduction and was 5.10inlb. We saw variation in the applied torque, which could have been due to the applied torques by the Occupational Therapist or the participant actively assisting or resisting the motion rather than remaining passive. We expect similar muscle and participant variation to exist with an assistive device. Thus, the data presented here can be used to inform the specifications for the development of an assistive thumb orthosis for children with "thumb-in-palm" deformity.

The results of surgical treatment for pronation deformities of the forearm in cerebral palsy after a mean follow-up of 17.5 years

Aim

This study evaluates the effects of three surgical procedures in the treatment of pronation deformities of the forearm in cerebral palsy patients; namely the transposition of pronator teres to extensor carpi radialis brevis muscle; and rerouting of the pronator teres muscle with or without pronator quadratus muscle myotomy.

Methods

Sixty-one patients, 48 male/13 female, with a mean age of 17 years (5–41 years) were treated between 1971 and 2011. Pronator teres transposition was performed in 10, pronator rerouting in 35, and pronator rereouting with pronator quadratus myotomy in 16 patients. Ranges of motion, and assessments using the Quick Dash, Mayo Scoring, and Functional Classification system of upper extremity, were made before and after surgery. Mean follow-up was 17.5 years (3–41 years).

Results

All three procedures led to significantly improved ranges of motion and upper limb function, with good/excellent results in 80 % of patients. Mean active supination improved from 10 ° (0–60 °) to 85 ° (30–90 °) (p < 0.001). There were significant improvements in Functional Classification system for the upper extremity scores (p < 0.003), Mean Quick Dash Scores improved from 58.41 (38.63–79.54) to 44.59 (27.27–68.18), and mean MEPS improved from 68 (30–85) to 84 (60–100) following surgery. All three techniques had statistically improved MEPS following surgery (p < 0.001); only the pronator teres muscle rerouting with pronator quadratus myotomy showed an improved Functional Classification system for the upper extremity score (p < 0.05); and only the pronator teres rerouting procedure showed an improved Quick Dash score (p < 0.05). There were no statistically significant differences in outcomes between different ages groups, and no significant differences between isolated pronator teres muscle rerouting were compared with those undergoing simultaneous treatment of carpal flexion and thumb adduction deformities (p > 0.05).

Conclusion

Surgery is very effective in the management of pronation deformities of the forearm in patients with cerebral palsy. Isolated pronator teres rerouting is probably the most effective and simple technique. Adjunctive pronator quadratus myotomy does not lead to an improvement in the results and requires an additional surgical approach. There should be no age restriction to surgery, as all age groups appear to benefit from similar improvements in range of motion and upper limb function.

SHUEE on the evaluation of upper limb in cerebral palsy

OBJECTIVE

To demonstrate the use of the tool for evaluation of spastic upper limb SHUEE (Shriners Hospital Upper Extremity Evaluation) in the evaluation of upper limb in cerebral palsy (CP) and its ability to detect changes after surgical treatment of identified deformities.

METHODS

19 patients with spastic hemiplegic CP had their upper limb evaluated by SHUEE. Five patients underwent surgical treatment of deformities detected and performed the test at one year postoperatively.

RESULTS

The mean age was 9.02 years old; 18 patients were classified as level I GMFCS and one patient as level II. At baseline, the mean spontaneous functional analysis was 59.01; dynamic positional analysis was 58.05 and grasp-and-release function, was 91.21. In the postoperative period the scores were, respectively, 65.73, 69.62 and 100, showing an improvement of 3.5% in the spontaneous functional analysis and of 44.8% in dynamic positional analysis.

CONCLUSIONS

SHUEE is a tool for evaluation of spastic upper limb in cerebral palsy that helps in the specific diagnosis of deformities, indication of treatment and objective detection of results after surgical treatment. Level of Evidence IV, Case Series.

Quantification of long-term effects of botulinum injection in a case of cerebral palsy affecting the upper limb movement

OBJECTIVE

The aim of this work was to put into evidence the long-lasting modification induced by botulinum toxin injection and rehabilitative treatment on motor control.

METHODS

In this contribution, we report the case of a female child showing hemiplegia, due to cerebral palsy. She underwent botulinum injection, followed by physical and occupational therapy. We quantified the biomechanical, cerebral and occupational aspects of her impaired upper limb, also dynamically, with respect to her pre- and post-treatment condition.

RESULTS

Small long-lasting improvements--induced on biomechanics by botulinum injection--triggered wide cerebral modification, well reflected in improved contextual movements and motor strategy.

CONCLUSION

These results provide evidences that small modifications in the end-effector performance often imply cerebral modifications and improvement in finalized motor strategy.

Upper limb function evaluation scales for individuals with cerebral palsy: a systematic review

[Purpose] The aim of the present study was to perform a systematic review of the literature on the scales and methods most often used for the evaluation of upper limb function in individuals with cerebral palsy. [Materials and Methods] Searches were conducted in the Medline, PEDro, Lilacs, Scielo, and PubMed databases. The following inclusion criteria were used for the selection of articles: randomized controlled study, evaluation of upper limb function in individuals with cerebral palsy, and publication between 2006 and 2014. The methodological quality of the articles was evaluated using the PEDro evidence scale. [Results] Five articles met the inclusion criteria and achieved 6 points or higher on the PEDro scale of methodological quality. [Conclusion] The studies analyzed used different evaluation scales, but no consensus has been reached thus far on which scale is the most appropriate. Thus, further studies are needed to establish an adequate method for the evaluation of upper limb function in individuals with cerebral palsy.

Management of the spastic wrist and hand in cerebral palsy

Research from the last 5 years on the pathophysiology and treatment of upper extremity sequelae of cerebral palsy (CP) is presented. The development of new treatments of CP-affected limbs, utilizing the brain's inherent neuroplasticity, remains an area of promising and active research. Functional magnetic resonance imaging scans have evaluated the role of neuroplasticity in adapting to the initial central nervous system insult. Children with CP appear to have greater recruitment of the ipsilateral brain for motor and sensory functions of the affected upper limb. Studies have also shown that constraint-induced movement therapy results in localized increase in gray matter volume of the sensorimotor cortex contralateral to the affected arm targeted during rehabilitation. Recent therapy interventions have emphasized the role of home therapy programs, the transient effects of splinting, and the promise of constraint-induced movement therapy and bimanual hand training. The use of motion laboratory analysis to characterize the movement pattern disturbances in children with CP continues to expand. Classification systems for CP upper limb continue to expand and improve their reliability, including use of the House Classification, the Manual Ability Classification System, and the Shriner's Hospital Upper Extremity Evaluation. Surgical outcomes have greater patients' satisfaction when they address functional limitations, also in addition to aesthetics, which may improve patients' self-esteem. Surgical techniques for elbow, wrist, fingers, and thumb continue to be refined. Research into each of these areas continues to expand our understanding of the nervous system insults that cause CP, how they may be modified, and how hand surgeons can continue to serve patients by improving their upper limb function and aesthetics.

Long term functional outcomes after early childhood pollicization

STUDY DESIGN

Retrospective Cohort

INTRODUCTION

Important outcomes of polliciation to treat thumb hypoplasia/aplasia include strength, function, dexterity, and quality of life.

PURPOSE OF THE STUDY

To evaluate outcomes and examine predictors of outcome after early childhood pollicization.

METHODS

8 children (10 hands) were evaluated 3-15 years after surgery. Physical examination, questionnaires, grip and pinch strength, Box and Blocks, 9-hole pegboard, and strength-dexterity (S-D) tests were performed.

RESULTS

Pollicized hands had poor strength and performance on functional tests. Six of 10 pollicized hands had normal dexterity scores but less stability in maintaining a steady-state force. Predictors of poorer outcomes included older age at surgery, reduced metacarpophalangeal and interphalangeal range of motion, and radial absence.

DISCUSSION

Pollicization resulted in poor strength and overall function, but normal dexterity was often achieved using altered control strategies.

CONCLUSIONS

Most children should obtain adequate dexterity despite weakness after pollicization except older or severely involved children.
