An exploration of the relationship between grit, reflection-in-learning, and academic performance in entry-level doctor of physical therapy students.

INTRODUCTION: Recent literature in physical therapy education suggests learners' non-cognitive skills, such as grit and reflection, may be predictors of success. Little is known about the relationship of these constructs to each other or success during the first year of entry level physical therapist education. OBJECTIVE: The purpose of this study was to assess the relationship between Reflection-In- Learning Scale (RLS), grit, and grade point average (GPA) of entry-level physical therapy students during the first year of didactic instruction. METHODS: One hundred and fourteen entry-level doctor of physical therapy students enrolled in a private university completed the original 12-item Grit Scale (Grit 1) and the RLS (RLS 1) during the first term and again at the end of the third trimester (Grit 2 and RLS 2). RESULTS: The relationship between Grit 1 and RLS 1 demonstrated a fair, positive, significant correlation (r = .380, p < .001). No relationship was found between Grit 1 and GPA (r = .066, p = .485), or Grit 2 and GPA (r = .064, p = .500), or between RLS 1 and GPA (r = .017, p = .857), or RLS 2 and GPA (r = .171, p = .069). Fifty-three percent of students demonstrated a decrease in grit and 56% decreased RLS scores at the end of the first year of the program. CONCLUSION: The fair correlation between these variables indicates they may measure different constructs. Findings suggest that doctor of physical therapy programs should be cautious when using these non-cognitive factors in making admission decisions. Future research should explore changes in grit and RLS throughout the curricula and impact on student success.

Current Trends for Children With Spina Bifida: A Survey of Pediatric Physical Therapists.

PURPOSE: To describe contemporary physical therapy practice and management of children with spina bifida (SB) in the context of the International Classification of Functioning, Disability, and Health (ICF) framework. METHODS: A descriptive, cross-sectional electronic survey was sent to US pediatric physical therapy clinics and posted in the American Physical Therapy Association Pediatrics newsletter. Data were analyzed using content analysis. Codes were compared, refined, and condensed into categories. RESULTS: A total of 163 participants were included. Most assessments evaluated the ICF Activity component. Most frequently reported ICF components: impairments = decreased strength (17.9%), activity limitations = limited walking (22.5%), and participation restrictions = restricted socializing/playing with peers or siblings (22.6%). The most prevalent intervention was strength training. CONCLUSIONS: Physical therapists (PTs) in the United States are performing assessments and interventions supported by available evidence; however, knowledge translation and more research are needed to support best practices in PT management of children with SB.

Relationship between Movement Quality, Functional Ambulation Status, and Spatiotemporal Gait Parameters in Children with Myelomeningocele.

AIMS: We investigated relationships among the Pediatric Neuromuscular Recovery Scale (Peds NRS), modified Hoffer Scale, and spatiotemporal gait parameters in children with myelomeningocele (MMC). METHODS: 21 children with MMC, age 5.3 years (SD = 2.6), were assessed by three clinicians using the Peds NRS and modified Hoffer Scale. In eight children, gait parameters were also measured. RESULTS: The Peds NRS summary score demonstrated good correlation with modified Hoffer Scale score (r = -0.64, p = 0.002) that accounted for 41% of variation in summary score. Six Peds NRS seated/standing items exhibited good relationships with modified Hoffer Scale (r = -0.51 to -0.70, p ≤ 0.023), and the sit-to-stand item demonstrated an excellent relationship (r = -0.85, p < 0.001). Sit-to-stand and three standing/walking items exhibited excellent associations with cadence (Rs = 0.81 to 0.88, p ≤ 0.014), and swing and stance time (both Rs = -0.83 to -0.90, p ≤ 0.01). Two Peds NRS standing items and modified Hoffer Scale score demonstrated good correlations with velocity (Rs = 0.71, p = 0.047; Rs = -0.73, p = 0.04, respectively). CONCLUSIONS: Our findings suggest that children with MMC who exhibit greater movement quality and trunk control are likely to be functional ambulators with more optimal spatiotemporal gait parameters.

Interrater Reliability of the Pediatric Neuromuscular Recovery Scale for Spinal Cord Injury.

Background: In synergy with the mounting scientific evidence for the capacity of recovery after spinal cord injury (SCI) and training, new evidence-based therapies advancing neuromuscular recovery are emerging. There is a parallel need for outcome instruments that specifically address recovery. The Pediatric Neuromuscular Recovery Scale (Pediatric NRS) is one example with established content validity to assess neuromuscular capacity within task performance. Objective: The objective of this study was to determine interrater reliability of the Pediatric NRS to classify motor capacity in children after SCI. Methods: Pediatric physicians (3), occupational therapists (5), and physical therapists (6) received standardized training in scoring the scale, then rated video assessments of 32 children post SCI, 2-12 years of age, 78% non-ambulatory. Interrater reliability was analyzed using Kendall coefficient of concordance for individual Pediatric NRS items and overall score. Results: The interrater reliability coefficient was determined to be near 1 for the overall Pediatric NRS score (ICC = 0.966; 95% CI, 0.89-0.98). Twelve of 16 individual items exhibited high concordance coefficients (Kendall's W ≥ 0.8) and four items demonstrated concordance coefficients, < 0.8 and > 0.69. Interrater reliability was equivalent among groups defined by age and neurological level, but lower among non-ambulatory individuals. Conclusion: Strong interrater reliability was demonstrated by pediatric clinicians who scored children with SCI using the Pediatric NRS.

Gross Motor Outcomes After Dynamic Weight-Bearing in 2 Children With Trunk Hypotonia: A Case Series.

INTRODUCTION: Children with trunk hypotonia may have limited ability to maintain an upright weight-bearing position, resulting in decreased postural control and a delay in achieving gross motor milestones. PURPOSE: The purpose of this case series is to report the effect of a home-based dynamic standing program on postural control and gross motor activity in 2 children with trunk hypotonia. DESCRIPTIONS: Child 1 (aged 24 months, Gross Motor Function Classification Scale Level IV) and Child 2 (aged 21 months, Gross Motor Function Classification Scale Level V) participated in a standing program using the Upsee harness at home 3 days per week for 12 weeks. OUTCOMES: Both children improved their gross motor function, and Child 1 demonstrated improved trunk control in sitting. WHAT THIS CASE ADDS: The use of the Upsee harness was an effective intervention for these children with trunk hypotonia to achieve weight-bearing and improve gross motor abilities.

Activity-Based Therapy: From Basic Science to Clinical Application for Recovery After Spinal Cord Injury.

BACKGROUND AND PURPOSE: Collaboration between scientists and clinicians effectively accelerated translation of scientific evidence for activity-based therapies (ABTs) into rehabilitation. This article addresses the basic scientific findings of activity-dependent plasticity that led to locomotor training, an ABT, and its principles to advance recovery in adult and pediatric populations with spinal cord injury (SCI). Expansion to new therapies based on these common principles is highlighted, for example, epidural stimulation. The article also describes a recently developed measure, the Neuromuscular Recovery Scale (NRS), and its psychometric properties. SUMMARY OF KEY POINTS: Locomotor training has led to recovery of walking in some individuals with motor-incomplete SCI even years after injury. Recent studies resulted in individuals with motor-complete SCI regaining some voluntary movements and standing in the presence of epidural stimulation. The level of success for locomotor training and epidural stimulation appears dependent on spinal networks maintaining the appropriate central state of excitability for the desired task. As these new advances in restorative therapies required an outcome measure that measured performance without compensation, the NRS was developed. The NRS has strong psychometric properties in adults, and a pediatric version is under development. Application of locomotor training in children is still novel. Preliminary evidence suggests that locomotor training can improve trunk control and also foster participation in children with chronic SCI. RECOMMENDATIONS FOR CLINICAL PRACTICE: ABTs may effectively promote neuromuscular recovery and improve function and participation in adults and children post-SCI. Evaluation of outcomes with valid measures, such as the NRS, is necessary to document the ability to perform functional tasks and to assess progress as function improves.

Development and Initial Validation of the Pediatric Neuromuscular Recovery Scale.

PURPOSE: The Neuromuscular Recovery Scale (NRS) was developed to assess the capacity of adults' post-spinal cord injury (SCI) to perform functional tasks without compensation. Application of the NRS to children has been challenging. The purpose of this study was to develop and complete the initial validation of a pediatric version of the NRS. METHODS: First, the investigative team developed a draft Pediatric NRS. Next, a Delphi method was used to amend the draft by 12 pediatric experts. Finally, the revised Pediatric NRS was field-tested on a sample of children with SCI (n = 5) and without (n = 7). RESULTS: After the Delphi process and field testing, the Pediatric NRS consists of 13 items scored on a 12-point scale. All items, except 1, achieved 80% agreement by experts. CONCLUSIONS: This is the first step in development and validation of a pediatric SCI scale that evaluates neuromuscular capacity, in the context of pediatric function, without compensation.

Assessment of Functional Improvement without Compensation for Human Spinal Cord Injury: Extending the Neuromuscular Recovery Scale to the Upper Extremities.

The Neuromuscular Recovery Scale (NRS) is a tool for measuring functional recovery in spinal cord injured (SCI) persons based on tasks that test pre-injury functional capability. The NRS has been shown to be a valid, reliable, and responsive instrument for measuring functional recovery. The NRS has been updated to include three items measuring upper extremity function, and a new scoring mechanism has been defined. The purpose of this prospective, observational study was to explore the properties of the expanded NRS, introduce and evaluate the new scoring method, and to examine the score's relationship with other SCI outcome measures. The NRS and seven other SCI outcome measures were assessed at enrollment and after every 20 locomotor training sessions in 64 participants of the NeuroRecovery Network (NRN) of the Christopher and Dana Reeve Foundation (CDRF). The NRS exhibited a dominant first principal component that correlated strongly with the new NRS score, as well as a potential secondary component discriminating upper extremity function. The new NRS score and its empirical subscales were generally well-correlated with International Standards for the Neurological Classification of Spinal Cord Injury (ISNCSCI) motor scores and other established SCI functional measures, but exhibited substantial variability at their boundary values. The NRS score was more strongly correlated with other SCI functional measures than ISNCSCI motor scores were. The new NRS score was most responsive to change brought on by locomotor training. The expanded NRS appears to be a valuable tool in measuring functional recovery from SCI; further evaluation of its psychometric properties is warranted.

Validity of the Neuromuscular Recovery Scale: a measurement model approach.

OBJECTIVE: To determine how well the Neuromuscular Recovery Scale (NRS) items fit the Rasch, 1-parameter, partial-credit measurement model. DESIGN: Confirmatory factor analysis (CFA) and principal components analysis (PCA) of residuals were used to determine dimensionality. The Rasch, 1-parameter, partial-credit rating scale model was used to determine rating scale structure, person/item fit, point-measure item correlations, item discrimination, and measurement precision. SETTING: Seven NeuroRecovery Network clinical sites. PARTICIPANTS: Outpatients (N=188) with spinal cord injury. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: NRS. RESULTS: While the NRS met 1 of 3 CFA criteria, the PCA revealed that the Rasch measurement dimension explained 76.9% of the variance. Ten of 11 items and 91% of the patients fit the Rasch model, with 9 of 11 items showing high discrimination. Sixty-nine percent of the ratings met criteria. The items showed a logical item-difficulty order, with Stand retraining as the easiest item and Walking as the most challenging item. The NRS showed no ceiling or floor effects and separated the sample into almost 5 statistically distinct strata; individuals with an American Spinal Injury Association Impairment Scale (AIS) D classification showed the most ability, and those with an AIS A classification showed the least ability. Items not meeting the rating scale criteria appear to be related to the low frequency counts. CONCLUSIONS: The NRS met many of the Rasch model criteria for construct validity.

Assessment of functional improvement without compensation reduces variability of outcome measures after human spinal cord injury.

OBJECTIVE: To develop a scale (Neuromuscular Recovery Scale [NRS]) for classification of functional motor recovery after spinal cord injury (SCI) based on preinjury movement patterns that would reduce variability of the populations' level of function within each class, because assessment of functional improvement after SCI is problematic as a result of high variability of the populations' level of function and the insensitivity to change within the available outcome measures. DESIGN: Prospective observational cohort with longitudinal follow-up. SETTING: Seven outpatient rehabilitation centers from the Christopher and Dana Reeve Foundation NeuroRecovery Network (NRN). PARTICIPANTS: Individuals (N=95) with American Spinal Injury Association Impairment Scale (AIS) grade C or AIS grade D having received at least 20 locomotor training treatment sessions in the NRN. INTERVENTIONS: Intensive locomotor training including stepping on a treadmill with partial body weight support and manual facilitation and translation of skills into home and community activities. MAIN OUTCOME MEASURES: Berg Balance Scale, six-minute walk test, and ten-meter walk test. RESULTS: Individuals classified within each of the 4 phases of the NRS were functionally discrete, as shown by significant differences in the mean values of balance, gait speed, and walking endurance, and the variability of these measurements was significantly reduced by NRS classification. The magnitude of improvements in these outcomes was also significantly different among phase groups. CONCLUSIONS: Assessment with the NRS provides a classification for functional motor recovery without compensation, which reduces variability in performance and improvements for individuals with injuries classified as AIS grades C and D.

Locomotor training: as a treatment of spinal cord injury and in the progression of neurologic rehabilitation.

Scientists, clinicians, administrators, individuals with spinal cord injury (SCI), and caregivers seek a common goal: to improve the outlook and general expectations of the adults and children living with neurologic injury. Important strides have already been accomplished; in fact, some have labeled the changes in neurologic rehabilitation a "paradigm shift." Not only do we recognize the potential of the damaged nervous system, but we also see that "recovery" can and should be valued and defined broadly. Quality-of-life measures and the individual's sense of accomplishment and well-being are now considered important factors. The ongoing challenge from research to clinical translation is the fine line between scientific uncertainty (ie, the tenet that nothing is ever proven) and the necessary burden of proof required by the clinical community. We review the current state of a specific SCI rehabilitation intervention (locomotor training), which has been shown to be efficacious although thoroughly debated, and summarize the findings from a multicenter collaboration, the Christopher and Dana Reeve Foundation's NeuroRecovery Network.

The ABLE scale: the development and psychometric properties of an outcome measure for the spinal cord injury population.

BACKGROUND: A paucity of information exists on the psychometric properties of several balance outcome measures. With the exception of the Modified Functional Reach Test, none of these balance outcome measures were developed specifically for the population with spinal cord injury (SCI). A new balance assessment tool for people with SCI, the Activity-based Balance Level Evaluation (ABLE scale), was developed and tested. OBJECTIVE: The purposes of this study were: (1) to develop a scale capturing the wide spectrum of functional ability following SCI and (2) to assess the initial psychometric properties of the scale using a Rasch analysis. DESIGN: A methodological research design was used to test the initial psychometric properties of the ABLE scale. METHODS: The Delphi technique was used to establish the original 28-item ABLE scale. People with SCI at each of 4 centers (n=104) were evaluated using the ABLE scale. A Rasch analysis was conducted to test for targeting, item difficulty, item bias, and unidimensionality. An analysis of variance was completed to test for discriminant validity. RESULTS: The Rasch analysis revealed a scale with minimal floor and ceiling effects and a wide range of item difficulty capturing the large scope of functional capacity after SCI. Multiple redundancies of item difficulty were observed. Limitations All raters were experienced physical therapists, which may have skewed the results. The sample size of 104 participants precluded a principal component analysis. CONCLUSION: Development of an all-inclusive clinical instrument assessing balance in the SCI population was accomplished using the Delphi technique. Modifications of the ABLE scale based on the Rasch analysis yielded a 28-item scale with minimal floor or ceiling effects. Larger studies using the revised scale and factor analyses are necessary to establish unidimensionality and reduction of the total item number.

Restorative rehabilitation entails a paradigm shift in pediatric incomplete spinal cord injury in adolescence: an illustrative case series.

Physical rehabilitation after spinal cord injury (SCI) in adult and pediatric populations has traditionally compensated for paralysis and weakness using wheelchairs, assistive devices, and braces to achieve seated mobility, upright standing, or bracewalking. Recent evidence indicates efficacy of activity-based therapies in adults with SCI, specifically locomotor training (LT), to activate the neuromuscular system below the injury level and improve walking and postural control by restoring pre-morbid movements. The purpose of this paper is to demonstrate the feasibility of LT, using repetitive stepping practice on a treadmill and translated to over ground and the community, to meet the unique needs and demands of pediatric, adolescent rehabilitation. Three outpatient adolescents, T5 AIS D, age 15 (primary wheelchair user), T5 AIS C, age 14 (primary wheelchair user), and C2, AIS D, 14 years (primary ambulator), received a standardized protocol of LT 4-5 times per week for 75, 293, and 40 total sessions, respectively, across 1-3 episodes of care. Two adolescents became full-time ambulators, and one adolescent improved locomotor skills, kinematics, and endurance with two individuals lacking significant increases in strength to account for the benefits. Motivational strategies were developmentally specific, parental involvement critical for carryover, and musculoskeletal considerations paramount with growth and maturation. In comparison to adults, adolescents' continued musculoskeletal, cognitive, and social growth and maturation necessitate repeated episodes of therapy and bi-annual re-evaluations to identify needs and address new goals. The use of activity-based therapies, i.e. LT, represents a paradigm shift in pediatric rehabilitation towards activation of the neuromuscular system below the lesion via task-specific training and experience, minimizing compensation strategies, and targeting recovery of function achieved via use of pre-morbid movement patterns.

A multivariate examination of temporal changes in Berg Balance Scale items for patients with ASIA Impairment Scale C and D spinal cord injuries.

OBJECTIVE: To provide a multivariate examination of the Berg Balance Scale (BBS) in patients with spinal cord injury (SCI) as a first step in developing a balance tool for the SCI population. DESIGN: Observational cohort. SETTING: The NeuroRecovery Network (NRN), a specialized network of treatment centers providing standardized, activity-based therapy for patients with SCI. PARTICIPANTS: Patients (N=97) with American Spinal Injury Association Impairment Scale C or D SCI who were enrolled in the NRN between March 1, 2005, and June 12, 2007. INTERVENTIONS: All enrolled patients received 3 to 5 locomotor training sessions a week, according to NRN protocol, and were periodically evaluated for progress on functional outcome measurements. MAIN OUTCOME MEASURES: Scores on the items of the BBS, six-minute walk test distances, ten-meter walk test speeds, and scores on the SCI Functional Ambulation Index. Temporal rates of change of the BBS items were examined with a principal components and correlation analysis. RESULTS: The first principal component accounted for nearly half of the overall variability in the BBS, correlated well with rates of change in functional mobility measures, and had good stability in its composition as verified by a resampling analysis. Further analysis showed that the composition of the first principal component varied with the patient's level of recovery. CONCLUSIONS: The BBS captures a significant amount of information about balance recovery in persons with SCI and may be a good foundation for a balance tool. However, the utility of BBS items may be dependent on a patient's level of recovery. A dynamic balance instrument for the SCI population may be needed.
