Students' Perception of Servant Leadership by Physical Therapy Faculty Mentors Is Associated With Interprofessional Socialization.

INTRODUCTION: Promoting interprofessional collaborative practice (IPCP) is necessary. Consequently, investigating strategies associated with increased interprofessional socialization, the beliefs, behaviors, and attitudes underlying socialization toward IPCP is suggested. The purpose of this study was to examine the relationship, in the presence of control variables, between students' perception of servant leadership by physical therapy faculty mentors and interprofessional socialization. REVIEW OF THE LITERATURE: Although faculty mentors are associated with influencing students' socialization process and servant leadership is suggested to support collaborative care, investigations exploring these concepts within physical therapy education are limited. SUBJECTS: Three cohorts of students (60 each) at an entry-level physical therapist education program in the Midwest of the United States. One hundred seventy individuals completed an anonymous paper-based composite survey, with 117 identifying the presence of an informal physical therapy faculty mentor. METHODS: This cross-sectional survey study, inclusive of student demographic control variables, examined the relationship between interprofessional socialization and perceptions of physical therapy faculty mentors, as measured by the Interprofessional Socialization and Valuing Scale (ISVS-21) and the Servant Leadership Measure (SL-7), respectively. Multiple linear regression was used to obtain the semi-partial correlation (sr) between the SL-7 and the ISVS-21, with significance accepted at P < .05. RESULTS: Upon necessary assumptions being met, 114 participants were included with an analysis of variance identifying the model to be significant (F(8,105) = 2.59, P = .01). Multiple linear regression analysis found that the SL-7, in the presence of control variables, was associated with a significant proportion of ISVS-21 scores (R2 = 0.17, F(8,105) = 2.59, P = .01). Notably, only the SL-7 demonstrated a significant contribution to ISVS-21 estimates (ß = 0.358, P < .001), with a significant and positive sr of 0.34 (P < .001). DISCUSSION AND CONCLUSION: Perceptions of servant leadership by faculty mentors were positively correlated with interprofessional socialization. Findings bolster the theoretical link between servant leadership and interprofessional socialization, servant leadership in the development of faculty and mentorship programs, and the relevance of informal social interactions.

Novel walking pole gait pattern improves activity in an older adult with chronic low back pain.

A 65-year-old woman with chronic low back pain participated in a 1-week community walking poles course. Although the participant received instruction in the standard Nordic walking method, she independently adopted a novel, modified, two-point gait pattern. Subsequently, her pain and activity tolerance using walking poles were monitored at 6 and 12 months. The participant ambulated two times the distance and reported lower ratings of perceived exertion and pain at 6-month and 12month follow-ups when walking with poles compared with walking without poles. This case highlights the potential effect of respecting patient preference within the clinical decision-making model. Doing so empowered a participant with chronic low back pain to adopt a novel, self-selected gait pattern and improve her short-term and long-term outcomes associated with chronic musculoskeletal disease.

A Community-based Boxing Program is Associated with Improved Balance in Individuals with Parkinson's Disease.

In alignment with efforts to mitigate the negative health consequences of Parkinson's Disease (PD), the purpose of this investigation was to examine if participation in a community-based boxing program (CBP) was associated with improvements in balance and fall risk reduction among individuals with PD. In this retrospective cross-sectional study, de-identified data from 12 individuals with PD participating in a CBP was examined. Participants included those with a Hoehn and Yahr stage between 1 and 3, averaging 2.8 ± 0.8 CBP sessions per week for 6.1 ± 0.8 months between testing. Baseline and re-evaluation testing included the Fullerton Advanced Balance (FAB) Scale and Timed Up and Go (TUG) to quantify balance and fall risk. Sessions were 90-minutes in length involving a warm-up, boxing drills, strength and endurance exercises, and cool down. Sessions included multiple bouts of 30-60 second high-intensity exercise intervals (RPE between 15/20 to 17/20). Paired t-tests were used to determine if differences existed between the FAB and TUG from baseline to re-evaluation, with statistical significance accepted at p < 0.05 and > 0.8 interpreted as a large effect using Cohen's d. Results indicated a statistically significant increase and large effect in FAB performance, with a mean increase in score above previously reported minimal detectable change (MDC). While participation in CBP was associated with a statistically significant improvement and medium effect in the TUG, this did not demonstrate a population specific MDC. This study found that participation in a CBP was associated with improved balance among clients with PD.

Force-Time Waveform Shape Reveals Countermovement Jump Strategies of Collegiate Athletes.

The purpose of this study was to relate the shape of countermovement jump (CMJ) vertical ground reaction force waveforms to discrete parameters and determine if waveform shape could enhance CMJ analysis. Vertical ground reaction forces during CMJs were collected for 394 male and female collegiate athletes competing at the National Collegiate Athletic Association (NCAA) Division 1 and National Association of Intercollegiate Athletics (NAIA) levels. Jump parameters were calculated for each athlete and principal component analysis (PCA) was performed on normalized force-time waveforms consisting of the eccentric braking and concentric phases. A K-means clustering of PCA scores placed athletes into three groups based on their waveform shape. The overall average waveforms of all athletes in each cluster produced three distinct vertical ground reaction force waveform patterns. There were significant differences across clusters for all calculated jump parameters. Athletes with a rounded single hump shape jumped highest and quickest. Athletes with a plateau at the transition between the eccentric braking and concentric phase (amortization) followed by a peak in force near the end of the concentric phase had the lowest jump height and slowest jump time. Analysis of force-time waveform shape can identify differences in CMJ strategies in collegiate athletes.

Relationship Between 2-Dimensional Frontal Plane Measures and the Knee Abduction Angle During the Drop Vertical Jump.

Context: Knee abduction angle (KAA), as measured by 3-dimensional marker-based motion capture systems during jump-landing tasks, has been correlated with an elevated risk of anterior cruciate ligament injury in females. Due to the high cost and inefficiency of KAA measurement with marker-based motion capture, surrogate 2-dimensional frontal plane measures have gained attention for injury risk screening. The knee-to-ankle separation ratio (KASR) and medial knee position (MKP) have been suggested as potential frontal plane surrogate measures to the KAA, but investigations into their relationship to the KAA during a bilateral drop vertical jump task are limited. Objective: To investigate the relationship between KASR and MKP to the KAA during initial contact of the bilateral drop vertical jump. Design: Descriptive. Setting: Biomechanics laboratory. Participants: A total of 18 healthy female participants (mean age: 24.1 [3.88] y, mass: 65.18 [10.34] kg, and height: 1.63 [0.06] m). Intervention: Participants completed 5 successful drop vertical jump trials measured by a Vicon marker-based motion capture system and 2 AMTI force plates. Main Outcome Measure: For each jump, KAA of the tibia relative to the femur was measured at initial contact along with the KASR and MKP calculated from planar joint center data. The coefficient of determination (r2) was used to examine the relationship between the KASR and MKP to KAA. Results: A strong linear relationship was observed between MKP and KAA (r2 = .71), as well as between KASR and KAA (r2 = .72). Conclusions: Two-dimensional frontal plane measures show strong relationships to the KAA during the bilateral drop vertical jump.

Development and Validation of a Portable and Inexpensive Tool to Measure the Drop Vertical Jump Using the Microsoft Kinect V2.

BACKGROUND: Noncontact anterior cruciate ligament (ACL) injury in adolescent female athletes is an increasing problem. The knee-ankle separation ratio (KASR), calculated at initial contact (IC) and peak flexion (PF) during the drop vertical jump (DVJ), is a measure of dynamic knee valgus. The Microsoft Kinect V2 has shown promise as a reliable and valid marker-less motion capture device. HYPOTHESIS: The Kinect V2 will demonstrate good to excellent correlation between KASR results at IC and PF during the DVJ, as compared with a "gold standard" Vicon motion analysis system. STUDY DESIGN: Descriptive laboratory study. LEVEL OF EVIDENCE: Level 2. METHODS: Thirty-eight healthy volunteer subjects (20 male, 18 female) performed 5 DVJ trials, simultaneously measured by a Vicon MX-T40S system, 2 AMTI force platforms, and a Kinect V2 with customized software. A total of 190 jumps were completed. The KASR was calculated at IC and PF during the DVJ. The intraclass correlation coefficient (ICC) assessed the degree of KASR agreement between the Kinect and Vicon systems. RESULTS: The ICCs of the Kinect V2 and Vicon KASR at IC and PF were 0.84 and 0.95, respectively, showing excellent agreement between the 2 measures. The Kinect V2 successfully identified the KASR at PF and IC frames in 182 of 190 trials, demonstrating 95.8% reliability. CONCLUSION: The Kinect V2 demonstrated excellent ICC of the KASR at IC and PF during the DVJ when compared with the Vicon system. A customized Kinect V2 software program demonstrated good reliability in identifying the KASR at IC and PF during the DVJ. CLINICAL RELEVANCE: Reliable, valid, inexpensive, and efficient screening tools may improve the accessibility of motion analysis assessment of adolescent female athletes.
