Clinical Outcomes of an Intensity Program for Children With Movement Challenges.

PURPOSE: Physical therapists at an outpatient pediatric facility developed and implemented an Intensity Program for children with movement challenges. The program was initiated on the basis of best evidence, parent advocacy, and clinician expertise. The purpose of this investigation is to analyze outcome data gathered from the program since 2012 to determine the effect of the program along with any specific child characteristics that were more likely to lead to positive outcomes. METHODS: A variety of outcome data were analyzed to compare preprogram performance with postprogram performance. RESULTS: Program participants made statistically significant and clinically important improvement in most outcome measures. Parents were highly satisfied with the program, including 98% of respondents who indicated that they would like to repeat their participation in the program. CONCLUSIONS: The results of this investigation suggest that many children with movement challenges are likely to benefit from participation in an Intensity Program.

Experiential Learning in Pediatric Physical Therapist Education: Challenges and Facilitators.

PURPOSE: The purpose of this study was to conduct an in-depth investigation of physical therapist educators' challenges to and facilitators of the use of experiential learning (EL) with children. Although EL with children has been called an essential component of doctor of physical therapy (DPT) education, variability in the amount of EL used among DPT programs indicates that educators may experience different challenges and facilitators of the use of EL. METHODS: Eighteen pediatric DPT educators participated in a semistructured interview. Researchers used thematic analysis to qualitatively analyze interview transcripts. RESULTS: Three themes emerged: (1) stakeholder considerations, (2) pedagogical considerations, and (3) logistical considerations. CONCLUSIONS: This research illustrates challenges and facilitators to the use of EL with children. How these challenges and facilitators are perceived by DPT educators has implications for faculty and program directors, particularly as they consider the use of EL with children in DPT programs nationally.

The How and the Why of Including Children: Experiential Learning in Teaching Physical Therapist Students.

PURPOSE: This study describes experiential learning (EL) activities with children and the rationale for using EL. Experiential learning with children in entry-level doctor of physical therapy (DPT) education has not been described. METHODS: Eighteen pediatric educators from accredited DPT programs participated in semistructured, in-depth interviews. Researchers analyzed written interview transcriptions using an iterative, consensus-building, thematic analysis approach. RESULTS: Educators described their EL activities. Educators' rationale for using EL grouped around 4 themes: (1) EL is valued by multiple stakeholders, (2) EL provides an additional learning modality, (3) EL introduces students to pediatric physical therapy, and (4) EL addresses standards and competencies for DPT education. CONCLUSIONS: This research provides a rich description of EL with children and rationale for integrating EL in DPT education. These findings may inform educators and program directors regarding the value of EL and the investment of resources to support EL in DPT education.

Experiential Learning in Pediatric Physical Therapist Education: Faculty and Student Perceptions.

SUBJECTS: Faculty teaching pediatric content in accredited doctor of physical therapy programs was recruited; 106 responded. Students representing 20 participating programs were also invited to participate; 23 responded. METHODS: Participants received an online questionnaire including closed- and open-ended questions regarding EL with children. Descriptive statistics were used to describe responses. Responses to open-ended questions were compiled and reviewed. RESULTS: Respondents reported an average of 12.4 hours of EL with children in required courses. Satisfaction with quality was stronger than with amount of EL. Several perceived barriers and facilitators were reported. CONCLUSIONS: Use of and satisfaction with EL with children in physical therapists' education vary. Continued research on this variation and potential effects to educational outcomes is needed.

Development of a Grading Rubric to Assess Learning in Pediatric Physical Therapy Education.

The purpose of this perspective article is to describe the development and potential use of a grading rubric to assess pediatric psychomotor and clinical reasoning skills in professional pediatric physical therapist students. Feedback from focus groups made up of pediatric physical therapy educators informed development of the rubric. In addition, preliminary reliability and feasibility of the rubric were evaluated using videotaped student performance on a related pediatric case. Pilot data suggest a range of reliability between slight and moderate across the components of the rubric. Both the case and the rubric are included as appendices, and recommendations are provided for implementation and for future research.

Pediatric Physical Therapists' Use of the Congenital Muscular Torticollis Clinical Practice Guidelines: A Qualitative Implementation Study.

PURPOSE: This study is a follow-up to the quantitative survey to examine the perceptions of pediatric physical therapists (PTs) on the application of the 2013 Congenital Muscular Torticollis Clinical Practice Guideline (CMT CPG). METHOD: Qualitative semi-structured telephone interviews were completed. Interview questions focused on how the guidelines influenced practice, facilitators and barriers to implementation, and knowledge translation activities. RESULTS: Thirteen pediatric PTs from a variety of practice settings participated. Positive perceptions about the CMT CPG included the use of flow charts, synthesized literature in one place, and validation of examination and intervention approaches. Negative perceptions included its length and that approaches without published evidence were not addressed. Three major themes were identified: knowledge and evidence for practice, education of clinicians, and the CPG structure and components that influenced practice. CONCLUSIONS: The CMT CPG provided a number of benefits. Recommendations for future enhancement and development are provided.

Changes in Local Bone Density in Early Thumb Carpometacarpal Joint Osteoarthritis.

PURPOSE: Thumb carpometacarpal (CMC) osteoarthritis (OA) represents a major source of functional morbidity. The effects of early CMC OA on loading and use patterns potentially lead to changes in local bone density and microarchitecture. Hounsfield units (HU), a quantitative attenuation coefficient obtained from computed tomography (CT) scans, have been shown to be a reliable marker of bone density. We hypothesized that early CMC OA is associated with lower local bone density about the CMC joint as assessed by HU. METHODS: We examined HU units from CT scans in 23 asymptomatic subjects and 91 patients with early CMC OA. The HU measurements were obtained within cancellous portions of the trapezium, capitate, first and third metacarpal bases, and distal radius. Linear regression models, with age and sex included as covariates, were used to assess the relationship between CMC OA and HU values at each anatomical site. RESULTS: Early OA patients had significantly lower HU than asymptomatic subjects within the trapezium (mean, 377 HU vs 436 HU) and first metacarpal bases (265 HU vs 324 HU). No significant group differences were noted at the capitate, third metacarpal, or distal radius. Male sex and younger age were associated with significantly higher HU at all the anatomical sites, except the first metacarpal base, where age had no significant effect. CONCLUSIONS: Subjects presenting with early CMC OA had significantly lower bone density as assessed with HU at the thumb CMC joint (trapezium and first metacarpal base). Early thumb CMC OA and discomfort may lead to diminished loading across the basal joint, producing focal disuse osteopenia. These findings in symptomatic early arthritis suggest a relationship between symptoms, functional use of the CMC joint, and local bone density. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic II.

Simple Assessment of Global Bone Density and Osteoporosis Screening Using Standard Radiographs of the Hand.

PURPOSE: Osteoporosis and fragility fractures have consequences both at the individual level and to the overall health care system. Although dual-energy x-ray absorptiometry (DXA) is the reference standard for assessing bone mineral density (BMD), other, simpler tools may be able to screen bone quality provisionally and signal the need for intervention. We hypothesized that the second metacarpal cortical percentage (2MCP) calculated from standard radiographs of the hand or wrist would correlate with hip BMD derived from DXA and could provide a simple screening tool for osteoporosis. METHODS: Two hundred patients who had hand or wrist radiographs and hip DXA scans within 1 year of each other were included in this series. Mid-diaphyseal 2MCP was calculated as the ratio of the cortical diameter to the total diameter. We assessed the correlation between 2MCP and total hip BMD. Subjects were stratified into normal, osteopenic, and osteoporotic cohorts based on hip t scores, and thresholds were identified to optimize screening sensitivity and specificity. RESULTS: Second metacarpal cortical percentage correlated significantly with BMD and t scores from the hip. A 2MCP threshold of less than 60% optimized sensitivity (88%) and specificity (60%) for discerning osteopenic subjects from normal subjects, whereas a threshold of less than 50% optimized sensitivity (100%) and specificity (91%) for differentiating osteoporotic from normal subjects. CONCLUSIONS: By demonstrating that global BMD may be assessed from 2MCP, these data suggest that radiographs of the hand and wrist may have a role in accurately screening for osteopenia and osteoporosis. This simple investigation, which is already used ubiquitously for patients with hand or wrist problems, may identify patients at risk for fragility fractures and allow for appropriate referral or treatment. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic II.

Uptake of the Congenital Muscular Torticollis Clinical Practice Guideline Into Pediatric Practice.

PURPOSE: This study describes survey responses about implementation of the congenital muscular torticollis clinical practice guideline (CMT-CPG) by pediatric physical therapists (PT) and successes and challenges with knowledge-brokering activities. METHODS: An online survey was distributed to pediatric PTs who self-identified with practice experience with congenital muscular torticollis. Data were analyzed for implementation frequency of guideline recommendations and differences pre and postpublication of the CMT-CPG. RESULTS: After publication, guideline recommendation implementation improved such that no recommendation was being implemented by less than 50% of respondents, and most were implemented by greater than 90%. The majority of respondents participated in knowledge brokering; however, many indicated minimal effectiveness of those activities. CONCLUSIONS: The CMT-CPG has successfully aided in changing practice. Participants identified areas of challenge and success in translating recommendations into practice and in knowledge brokering that may be helpful for the development of future CPGs.

Using Hounsfield Units to Assess Osteoporotic Status on Wrist Computed Tomography Scans: Comparison With Dual Energy X-Ray Absorptiometry.

PURPOSE: Rates of evaluation and treatment for osteoporosis following distal radius fragility fractures remain low. As a subset of patients with these fractures undergo diagnostic computed tomography (CT) scan of the wrist, utilizing bone mineral density (BMD) measurements available with this imaging can be used to detect osteopenia or osteoporosis. This information may consequently prompt intervention to prevent a subsequent fracture. The purpose of this study was to determine if Hounsfield unit (HU) measurements at the wrist correlate with BMD measurements of the hip, femoral neck, and lumbar spine and to assess the ability of these HU measurements to detect osteoporosis of the hip. METHODS: Forty-five female patients with distal radius fractures who underwent CT scan and dual energy x-ray absorptiometry scan as part of the management of their wrist fracture were identified. Bone mineral density measurements were made using the regional cancellous bone HU value at the capitate and compared with values obtained by a dual energy x-ray absorptiometry scan. RESULTS: Hounsfield unit values at the capitate were significantly correlated with BMD and t scores at the femoral neck, hip, and lumbar spine. An HU threshold of 307 in the capitate optimized sensitivity (86%) and specificity (94%) for detecting osteoporotic patients. CONCLUSIONS: By demonstrating that capitate HU measurements from clinical CT scans are correlated with BMD and t scores at the hip, femoral neck, and lumbar spine, our data suggest that clinical CT scans should have a role in detecting osteopenia and osteoporosis. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic III.

Axon Counts Yield Multiple Options for Triceps Fascicular Nerve to Axillary Nerve Transfer.

PURPOSE: To evaluate the relative axonal match between potential donor and recipient nerves, so that maximal reinnervation potential may be reached with the least chance of donor site morbidity. METHODS: In 10 fresh-frozen cadaveric specimens, the main trunk and anterior, posterior, sensory and teres minor branches of the axillary nerve were identified, as were the radial nerve branches to the long, medial, and lateral heads of the triceps. The swing distances of the triceps fascicular nerve branches and the axillary nerve branches relative to the inferior border of the teres major muscle were recorded. Histomorphological analysis and axon counts were performed on sections of each branch. RESULTS: The median number of axons in the main axillary trunk was 7,887, with 4,052, 1,242, and 1,161 axons in the anterior, posterior, and teres minor branches, respectively. All specimens had a single long head triceps branch (median, 2,302 axons), a range of 1 to 3 branches to the medial head of the triceps (composite axon count, 2,198 axons), and 1 to 3 branches to the lateral head of the triceps (composite average, 1,462 axons). The medial and lateral head branches had sufficient swing distance to reach the anterior branch of the axillary nerve in all 10 specimens, with only 4 specimens having adequate long head branch swing distances. CONCLUSIONS: It is anatomically feasible to transfer multiple branches of the radial nerve supplying the medial, lateral, and sometimes, long head of the triceps to all branches of the axillary nerve in an attempt to reinnervate the deltoid and teres minor muscles. CLINICAL RELEVANCE: Understanding the axon counts of the different possible transfer combinations will improve operative flexibility and enable peripheral nerve surgeons to reinnervate for both abduction and external rotation with the highest donor/recipient axon count ratios.

Conservative management of elbow dislocations with an overhead motion protocol.

PURPOSE: To report the results of using an overhead motion protocol in 27 patients and to assess final range of motion and incidence of persistent instability in this cohort. METHODS: A total of 27 patients were included who sustained a simple elbow dislocation and were treated nonsurgically with an overhead motion protocol designed to convert gravity from a distracting to a stabilizing force. Motion was initiated within 1 week of injury and average follow-up was 29 months. Final arc of motion and prevalence of instability were the primary outcomes measures. RESULTS: Final mean arc of extension to flexion was from 6° to 137°, and of pronation to supination was from 87° to 86°. No recurrent instability was observed in this cohort and all patients were fully functional and without limitations at latest follow-up. CONCLUSIONS: The overhead motion protocol was a reliable rehabilitation program after elbow dislocation that allowed for controlled early motion by placing the elbow in an inherently stable position. Prompt initiation of motion in a protected position can optimize final motion and satisfaction outcomes, and when done in a mechanically advantageous position it can potentially limit the risk of recurrent instability. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Experiential Learning With Children: An Essential Component of Professional Physical Therapy Education.

PURPOSE: The Section on Pediatrics of the American Physical Therapy Association has developed a number of resources to support and improve the consistency of professional pediatric physical therapy education, including a set of core competencies that all graduates must attain. The purpose of this article is to advocate for the inclusion of experiential learning activities with children, including children with participation restrictions, as a necessary component to achieve the core competencies. KEY POINTS: Experiential learning is a form of practice-based education that provides exposures and opportunities for students to explore the work, roles, and identities they will encounter as future professionals. Experiential learning is learning by doing, and occurs within a relevant setting. Six representative curricular exemplars are presented to provide readers with a variety of suggestions for development and integration of experiential learning. SUMMARY: Recommendations for future research are provided and 4 key recommendations are provided.

Use of computed tomography for assessing bone mineral density.

Assessing local bone quality on CT scans with Hounsfield unit (HU) quantification is being used with increasing frequency. Correlations between HU and bone mineral density have been established, and normative data have been defined throughout the spine. Recent investigations have explored the utility of HU values in assessing fracture risk, implant stability, and spinal fusion success. The information provided by a simple HU measurement can alert the treating physician to decreased bone quality, which can be useful in both medically and surgically managing these patients.

Thoracic outlet syndrome caused by synostosis of the first and second thoracic ribs: 2 case reports and review of the literature.

We present 2 cases of combined arterial and neurogenic thoracic outlet syndrome triggered by trauma in patients with congenital synostoses of the first and second ribs. These patients were successfully treated with supraclavicular resection of the first and second ribs and scalenectomy. We review these cases and the associated literature on thoracic outlet syndrome and rib synostosis.

Preoperative donor nerve electromyography as a predictor of nerve transfer outcomes.

PURPOSE: We hypothesized that health of the donor nerve and corresponding muscle, as assessed by electromyography (EMG), could predict the outcome of nerve transfer surgery. METHODS: A retrospective review was performed to investigate outcomes of nerve transfers for elbow flexion and shoulder abduction. Motor strength was graded preoperatively and after a minimum 1-year follow-up. Preoperative EMG results were classified as functionally normal or affected based on motor unit recruitment pattern and correlated with follow-up motor strength and range of motion. RESULTS: Forty nerve transfers were identified: 27 were performed for elbow flexion and 13 for shoulder abduction. Overall, the 29 transfers in the normal EMG cohort showed significantly greater postoperative improvement in motor strength (Medical Research Council grade 0.2-4.1) than the 11 transfers in the affected EMG cohort (grade 0.0-3.0). In the shoulder cohort, normal donor nerves resulted in greater strength (grade 4.0 vs. 2.4) and active motion (83° vs. 25°) compared with affected donor nerves. Double fascicular transfers with 2 normal donor nerves demonstrated improved strength compared with double nerve transfers when 1 donor nerve was affected (grade 4.5 vs. 3.2). CONCLUSIONS: Our findings demonstrate that a simple EMG classification that describes the quality of donor nerves can predict outcome as measured by postoperative motor strength and range of motion. Preoperative EMG evaluation should be considered a valuable supplementary component of the donor nerve selection process when planning brachial plexus reconstruction. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Magnetic resonance imaging findings in acute elbow dislocation: insight into mechanism.

PURPOSE: To identify with magnetic resonance imaging the location and severity of ligamentous injury after acute elbow dislocations. Based on observations that many elbow dislocations arise from an initial acute valgus load, we hypothesized that all patients would have a high-grade medial injury but not all would demonstrate injury of the lateral ligaments. METHODS: The medial collateral ligament was subdivided into anterior bands of the anterior bundle of the medial collateral ligament (MCL) and posterior bands of the anterior bundle of the MCL, whereas the lateral collateral ligament was divided into the lateral ulnar collateral ligament and the radial collateral ligament. Distinction on magnetic resonance imaging was made between normal morphology and low-grade partial tear (< 50% of the ligament fibers), high-grade partial tear (≥ 50%), and full-thickness disruption. The site of disruption was also characterized. RESULTS: Acute magnetic resonance imaging studies for 16 patients were included. No low-grade tears or intact evaluations of either the anterior or posterior bands of the anterior bundle of the MCL were observed; most demonstrated complete tears. The lateral ulnar collateral ligament most frequently showed complete disruption but was occasionally intact. The radial collateral ligament infrequently showed full disruption. Complete tears involving either the anterior or posterior portions of the anterior band of the MCL were significantly more common than complete tears involving the ligaments on the lateral side. CONCLUSIONS: After elbow dislocation, complete ligamentous tears were more common on the medial versus the lateral side. Whereas the lateral ligaments were occasionally preserved, this was never observed on the medial side. These data suggest a sequence of failure starting on the medial side with subsequent variable energy dissipation laterally. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic IV.

Direct repair for managing acute and chronic lateral ulnar collateral ligament disruptions.

PURPOSE: Acute elbow injuries that disrupt the lateral ulnar collateral ligament and result in posterolateral rotatory instability usually require surgical treatment. The 2 technical options reported, direct repair and use of a palmaris longus tendon graft, have usually favored the use of the graft. To balance this emphasis, we report our experience with direct repair of the humeral origin in cases of trauma, whether acute, delayed, or recurrent. It was our hypothesis that because the humeral origin is the point of failure and separation, restoration of this attachment is sufficient to restore stability and durable function without the need for a graft. METHODS: Patients with complete disruption of the posterolateral ligaments of the elbow, who were managed with direct repair to the humeral origin, were included. Patients were separated into an acute treatment group (< 30 d from injury to treatment) and a delayed treatment group (> 30 d). Mayo Elbow Performance Scores and postoperative range of motion were collected from patient records. RESULTS: A total of 34 patients were included with a mean follow-up of 42 months. No difference was seen in Mayo Elbow Performance Scores between acute (mean, 90) or delayed treatment (mean, 89) of the lateral ulnar collateral ligament tear. No difference was seen in final elbow flexion or extension. Two patients in the acute group had failure of the direct repair requiring intervention. In the delayed group, no patients had recurrent instability. CONCLUSIONS: No significant difference in clinical outcome or range of motion was observed after direct repair of traumatic tears of the lateral ulnar collateral ligament tear between acute and delayed treatment cohorts. Despite complete disruption of the posterolateral ligaments, direct repair of the torn ligament to its humeral origin was effective without supplemental tendon graft reconstruction irrespective of interval from injury to repair, mechanism of injury, or associated fractures. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic III.

Outcomes of anconeus interposition for proximal radioulnar synostosis.

BACKGROUND/HYPOTHESIS: Proximal radioulnar synostosis after elbow injuries can produce debilitating contractures. The estimated range of motion required to perform many activities of daily living is a 100° arc of forearm rotation. We hypothesized that excision of heterotopic bone and anconeus flap interposition could restore functional prono-supination in patients with proximal radioulnar synostosis. METHODS: Patients with proximal radioulnar synostosis were subdivided into 2 groups on the basis of etiology: (1) as a complication after distal biceps tendon repair or (2) as a result of direct trauma to the proximal forearm/elbow. All patients underwent an excision of the synostosis with interposition of an anconeus flap and were observed clinically for a minimum of 6 months. RESULTS: Twenty-three patients (16 men, 7 women) were included, with a mean age of 47 years and mean clinical follow-up of 4.8 years. Mean arc of forearm rotation improved from 21° to 132°, pronation increased from 12° to 70°, and supination increased from 9° to 62° (P < .0001). Patients with biceps tendon repair etiology (n = 7) displayed greater gains in pronation and a trend toward greater total forearm rotation than did those with a traumatic etiology (n = 16). CONCLUSION: Anconeus interposition flap for management of proximal radioulnar synostosis produces significant and reliable clinical improvement in elbow prono-supination. Patients with biceps tendon repair etiology had a trend toward greater motion improvement than that of patients with a traumatic etiology. The degree of improvement seen would provide nearly full restoration of functional motion, resulting in minimal limitations in activities of daily living.
