Item Open Access Assessment of Disability Related to Hip Dysplasia Using Objective Measures of Physical Performance.(Orthopaedic journal of sports medicine, 2020-02) Scott, Elizabeth J; Willey, Michael C; Mercado, Arthur; Davison, John; Wilken, Jason MBackground
Lower extremity physical performance measures (PPMs), which can objectively quantify functional ability, are an attractive adjuvant to patient-reported outcome (PRO) instruments. However, few tests have been validated for use in hip instability.Purpose
To evaluate 4 different PPMs for their ability to differentiate between young adults with hip dysplasia indicated for treatment with periacetabular osteotomy (PAO) and asymptomatic controls and to test inter- and intratest reliability and relationship with popular hip PRO instruments.Study design
Cohort study (diagnosis); Level of evidence, 2.Methods
A total of 24 symptomatic patients aged 15 to 39 years (100% female) with hip dysplasia (lateral center-edge angle <25°) indicated for treatment with PAO completed the visual analog scale (VAS) for pain, Hip disability and Osteoarthritis Outcome (HOOS) Pain subscale, HOOS Short Version (HOOS PS), International Hip Outcome Tool Short Version (iHOT-12), modified Harris Hip Score (mHHS), Patient Reported Outcome Measurement Information System (PROMIS) physical function (PF) and pain interference (PI), and 4 physical function tests: (1) self-selected walking speed (SSWS), sit-to-stand 5 times (STS5), (3) 4-square step test (FSST), and (4) timed stair ascent (TSA). A further 21 young, asymptomatic adults aged 18 to 39 years (91% female) also underwent testing. Between-group comparisons were made with unpaired t test with Bonferroni-Holm correction. Inter- and intrarater reliability was assessed in 38 participants by repeating PPMs at a second visit and using 2 raters. Spearman rank correlation coefficients were used to determine associations between PPMs and PRO instruments.Results
Significant differences between patients with hip dysplasia and controls were observed for all PRO instruments (HOOS Pain, 47.8 vs 99.2; HOOS PS, 61.9 vs 99.2; iHOT-12, 32.2 vs 99.2; mHHS, 54.5 vs 90.6; PROMIS PF, 41.4 vs 65.6; and PROMIS PI, 62.0 vs 39.1 [all P < .001]), and all PPMs (SSWS, 1.21 vs 1.53 m/s; STS5, 10.85 vs 5.95 s; FSST, 6.59 vs 4.03 s [all P < .001]; and TSA, 4.58 vs 3.29 s [P = .002]). All 4 PPMs demonstrated excellent intra- and intertest reliability (intraclass correlation coefficient, 0.83-0.99). STS5, FSST, and TSA were correlated highly (r > 0.5) with physical function PRO instruments, including PROMIS PF, mHHS, and iHOT-12.Conclusion
Patients with symptomatic hip dysplasia demonstrated significant impairment on functional testing compared with asymptomatic controls, and performance measure testing demonstrated excellent test-retest reliability. Timed stair ascent and sit-to-stand testing in particular were correlated strongly with physical function PRO instruments. PPMs may be a viable and well-received adjuvant to PRO instrument administration for patients with nonarthritic hip conditions, and investigation of the ability of PPMs to assess surgical outcomes for hip dysplasia is warranted.Item Open Access Learning to Listen, Learning to Be: African-American Girls and Hip-Hop at a Durham, NC Boys and Girls Club(2009) Woodruff, Jennifer AnnThis dissertation documents African-American girls' musical practices at a Boys and Girls Club in Durham, NC. Hip-hop is the cornerstone of social exchanges at John Avery, and is integrated into virtually all club activities. Detractors point to the misogyny, sexual exploitation and violence predominant in hip-hop's most popular incarnations, suggesting that the music is a corrupting influence on America's youth. Girls are familiar with these arguments, and they appreciate that hip-hop is a contested and sometimes illicit terrain. Yet they also recognize that knowledge about and participation in hip-hop-related activities is crucial to their interactions at the club, at school, and at home. As girls hone their listening skills, they reconcile the contradictions between behavior glorified by hip-hop and the model presented to them by their mentors. This project examines how African-American girls ages 5-13 use their listening practices to claim a space within hip-hop's landscape while still operating within the unambiguous moral framework they have learned from their parents, mentors and peers. Through ethnography and close analysis of vocal utterances, dance moves and social interaction, I consider how individual interactions with mass-mediated music teach girls a black musical aesthetic that allows them to relate to their peers and mentors, and how these interactions highlight the creativity with which they begin to negotiate sexual and racial politics on the margins of society.
Item Open Access Patient expectation is the most important predictor of discharge destination after primary total joint arthroplasty.(J Arthroplasty, 2015-04) Halawi, Mohamad J; Vovos, Tyler J; Green, Cindy L; Wellman, Samuel S; Attarian, David E; Bolognesi, Michael PThe purpose of this study was to identify preoperative predictors of discharge destination after total joint arthroplasty. A retrospective study of three hundred and seventy-two consecutive patients who underwent primary total hip and knee arthroplasty was performed. The mean length of stay was 2.9 days and 29.0% of patients were discharged to extended care facilities. Age, caregiver support at home, and patient expectation of discharge destination were the only significant multivariable predictors regardless of the type of surgery (total knee versus total hip arthroplasty). Among those variables, patient expectation was the most important predictor (P < 0.001; OR 169.53). The study was adequately powered to analyze the variables in the multivariable logistic regression model, which had a high concordance index of 0.969.Item Open Access Preoperative pain level and patient expectation predict hospital length of stay after total hip arthroplasty.(J Arthroplasty, 2015-04) Halawi, Mohamad J; Vovos, Tyler J; Green, Cindy L; Wellman, Samuel S; Attarian, David E; Bolognesi, Michael PThe purpose of this study was to identify preoperative predictors of length of stay after primary total hip arthroplasty in a patient population reflecting current trends toward shorter hospitalization and using readily obtainable factors that do not require scoring systems. A retrospective review of 112 consecutive patients was performed. High preoperative pain level and patient expectation of discharge to extended care facilities (ECFs) were the only significant multivariable predictors of hospitalization extending beyond 2 days (P=0.001 and P<0.001 respectively). Patient expectation remained significant after adjusting for Medicare's 3-day requirement for discharge to ECFs (P<0.001). The study was adequately powered to analyze the variables in the multivariable logistic regression model, which had a concordance index of 0.857.
