Patient- and Physical Therapist-Level Predictors of Patient-Reported Therapeutic Alliance: An Observational, Exploratory Study of Cohorts With Knee and Low Back Pain.

OBJECTIVE: To identify patient- and physical therapist-level predictors for therapeutic alliance at the end of an episode of physical therapy for knee or low back pain (LBP). DESIGN: Secondary analysis of observational cohort. SETTING: Outpatient physical therapy clinics. PARTICIPANTS: Patients receiving physical therapy for knee (n=189) or LBP (n=252) and physical therapists (n=19). Candidate predictor variables included demographics, patient clinical characteristics, and physical therapist attitudes and beliefs (Pain Attitudes and Beliefs Scale for Physical Therapists) and confidence in providing patient-centered care (Self-Efficacy in Patient-Centeredness Questionnaire). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Patient-reported therapeutic alliance was measured using the 12-item Work Alliance Inventory-Short Revised (WAI-SR). RESULTS: Final linear mixed models indicated different patient- and physical therapist-level factor contributions in predicting final WAI-SR scores across cohorts with knee and LBP. Female sex was a consistent patient-level predictor for both knee (estimated ß=1.57, P<.05) and LBP (ß=1.42, P<.05), with age (ß=-0.07, P<.01) and baseline function (ß=0.06, P<.01) contributing to cohorts with knee and LBP, respectively. Physical therapist-level predictors included female sex (ß=6.04, P<.05), Pain Attitudes and Beliefs Scale for Physiotherapists behavioral (ß=0.65, P<.01), and Self-Efficacy in Patient-Centeredness Questionnaire (SEPCQ) Exploring Patient Perspective (ß=-0.75, P<.01) subscale scores for LBP, with SEPCQ Sharing Information and Power subscale scores (ß=0.56, P<.05) contributing to both cohorts with knee (ß=0.56, P<.05) and LBP (ß=0.74, P<.01). Random effects for patients nested within physical therapists were observed for both cohorts. CONCLUSIONS: These findings provide preliminary evidence for inconsistent relationships among patient- and physical therapist-level factors and therapeutic alliance across cohorts with knee and LBP.

Prevalence of low back pain and related disability in patients with femoroacetabular impingement syndrome.

BACKGROUND: Low back pain (LBP) has been associated with worse hip function for persons with femoroacetabular impingement syndrome (FAIS). Reports are limited to surgical populations and based on the presence or absence of LBP, regardless of pain severity. OBJECTIVES: To report the prevalence of clinically significant LBP for persons with FAIS; compare demographics, pain, and function between those with and without clinically significant LBP; and evaluate relationships between hip function and both LBP-related disability and LBP severity. We hypothesized that participants with LBP would be older, have higher body mass index (BMI), and report worse groin pain, longer symptom duration, and worse hip function. We hypothesized that worse LBP-related disability and LBP severity would be related to worse hip function. DESIGN: Observational cross-sectional study. SETTING: Hip preservation clinic. PARTICIPANTS: 158 persons with FAIS. INTERVENTIONS: n/a MAIN OUTCOME MEASURE(S): Visual analog pain scales (VAS 0-100) were used to categorize participants with (≥30) and without (<30) clinically significant LBP. Age, sex, BMI, pain severity and duration, and hip function (33-item Hip Outcome Tool [iHOT33]) were compared between those with and without clinically significant LBP. Correlations were evaluated between the modified Oswestry Disability Index (ODI) and iHOT33, ODI and groin pain severity, LBP severity and iHOT33, and LBP and groin pain severity. RESULTS: Sixty percent of participants reported clinically significant LBP (n = 95). These participants reported worse iHOT33 scores (mean difference: 10.1 points) than those without clinically significant LBP (p = .001). Worse ODI scores were associated with worse iHOT33 scores (P < .001; ρ = -0.74). Significant relationships were also observed between (1) ODI and groin pain, (2) LBP and iHOT33, and (3) LBP and groin pain, but the magnitudes of these correlations were weak (ρ ≤ 0.36). CONCLUSIONS: Clinically significant LBP is highly prevalent in persons with FAIS and is associated with worse hip function. Worse LBP-related disability, but not LBP severity, was strongly associated with worse hip function.

Treatment decisions after interdisciplinary evaluation for nonarthritic hip pain: A randomized controlled trial.

BACKGROUND: Physical therapy and hip arthroscopy are two viable treatment options for patients with nonarthritic hip pain (NAHP); however, patients may experience considerable decisional conflict when making a treatment decision. Interdisciplinary evaluation with a physical therapist and surgeon may better inform the decision-making process and reduce decisional conflict. OBJECTIVE: To identify the extent to which an interdisciplinary evaluation between a surgeon, physical therapist, and patient influences treatment plans and decisional conflict of persons with NAHP. DESIGN: Randomized controlled trial. SETTING: Hip preservation clinic. PARTICIPANTS: Adults with primary NAHP. INTERVENTIONS: Participants were randomized to receive a standard (surgeon) or interdisciplinary (surgeon+physical therapist) evaluation. Surgeon evaluations included patient interview, strength and range-of-motion examination, palpation, gross motor observation, and special testing. Interdisciplinary evaluations started with the surgeon evaluation, then a physical therapist evaluated movement impairments during sitting, sit-to-stand, standing, single-leg stance, single-leg squat, and walking. All evaluations concluded with treatment planning with the respective provider(s). OUTCOME MEASURES: Treatment plan and decisional conflict were collected pre- and postevaluation. Inclusion of physical therapy in participants' postevaluation treatment plans and postevaluation decisional conflict were compared between groups using chi-square tests and Mann-Whitney U tests, respectively. RESULTS: Seventy-eight participants (39 in each group) met all eligibility criteria and were included in all analyses. Sixty-six percent of participants who received an interdisciplinary evaluation included physical therapy in their postevaluation treatment plan, compared to 48% of participants who received a standard evaluation (p = .10). Participants who received an interdisciplinary evaluation reported 6.3 points lower decisional conflict regarding their postevaluation plan (100-point scale; p = .04). The interdisciplinary and standard groups reduced decisional conflict on average 24.8 ± 18.9 and 23.6 ± 14.6 points, respectively. CONCLUSIONS: Adding a physical therapist to a surgical clinic increased interest in physical therapy treatment, but this increase was not statistically significant. The interdisciplinary group displayed lower postevaluation decisional conflict; however, both groups displayed similar reductions in decisional conflict from pre- to postevaluation. This study also demonstrated the feasibility of an interdisciplinary evaluation in a hip preservation clinic.

Relationships between physical therapy intervention and opioid use: A scoping review.

OBJECTIVE: To synthesize available evidence that has examined the relationship between physical therapy (PT) and opioid use. TYPE: Scoping Review LITERATURE SURVEY: Data sources including Google Scholar, Embase, PubMed, Cochrane Library, and CINAHL were searched for English articles up to October 24, 2019 using terms ("physical therapy"[Title/Abstract] OR physiotherapy[Title/Abstract] OR rehabilitation[Title/Abstract]) AND (opiate*[Title/Abstract] OR opioid*[Title/Abstract]). METHODOLOGY: Included studies evaluated a PT intervention and reported an opioid-use outcome. Data were extracted to describe the PT intervention, patient sample, opioid-use measurement, and results of any time or group comparisons. Study quality was evaluated with Joanna Briggs checklists based on study design. SYNTHESIS: Thirty studies were included that evaluated PT in at least one of these seven categories: interdisciplinary program (n = 8), modalities (n = 3), treatment (n = 3), utilization (n = 2), content (n = 3), timing (n = 13), and location (n = 2). Mixed results were reported for reduced opioid-use after interdisciplinary care and after PT modalities. Utilizing PT was associated with lower odds (ranging from 0.2-0.8) of using opioid medication for persons with low back pain (LBP) and injured workers; however, guideline-adherent care did not further reduce opioid use for persons with LBP. Early PT utilization after index visit for spine or joint pain and after orthopedic surgery was also associated with lower odds of using opioid medications (ranging from 0.27-0.93). Emergency department PT care was not associated with fewer opioid prescriptions than standard emergency department care. PT in a rehabilitation center after total knee replacement was not associated with lower opioid use than inpatient PT. CONCLUSIONS: The relationship between timing of PT and opioid use was evaluated in 13 of 30 studies for a variety of patient populations. Eight of these 13 studies reported a relationship between early PT and reduced subsequent opioid use, making the largest sample of studies in this scoping review with supporting evidence. There is limited and inconclusive evidence to establish whether the content and/or location of PT interventions improves outcomes because of heterogeneity between studies.

Movement Patterns and Their Associations With Pain, Function, and Hip Morphology in Individuals With Femoroacetabular Impingement Syndrome: A Scoping Review.

OBJECTIVE: The purpose of the study was to synthesize studies of movement patterns and their association with hip pain, function/activity, and morphology in individuals with femoroacetabular impingement syndrome (FAIS). METHODS: PubMed, SPORTDiscus, CINAHL, Embase, and Scopus databases were searched using predefined terms. Two authors independently reviewed abstracts and full texts. Studies were included if they enrolled individuals with FAIS, reported kinematic or kinetic data during movement tasks, and tested the data's associations with hip pain, function/activity, or morphology. Exclusion criteria were studies that did not evaluate associations between movement patters and pain, function/activity, or hip morphology. Additionally, studies with hip conditions other than FAIS, case reports, conference proceedings, review articles, and non-English studies were excluded. Descriptive consolidation and qualitative synthesis were performed for the included studies. RESULTS: Of the 1155 potential studies, 5 studies met all eligibility criteria. Movement patterns were evaluated during walking (n = 4) and squatting (n = 1). Studies reported multiple associations between variables of interest. Statistically significant associations were identified between movement patterns and hip pain (n = 2), function/activity (n = 2), or morphology (n = 3). Significant associations included increased hip flexion moment impulse during walking was associated with worse pain, increased hip flexion moment during walking was associated with worse hip function, decreased hip external rotation during gait and hip internal rotation during squat were associated with larger cam deformity, and increased hip flexion moment impulse during walking was also associated with more severe acetabular cartilage abnormalities. CONCLUSIONS: Very little current evidence has evaluated the associations between altered movement patterns and hip pain, function/activity, or morphology in individuals with FAIS, and only low-intensity tasks have been tested. These studies found some preliminary associations between altered hip biomechanics and higher hip pain, worse hip function, and specific measures of hip morphology in individuals with FAIS. IMPACT: This review is a first step in gaining a better understanding of movement patterns and their associations with hip pain, function/activity, and morphology, which could ultimately assist with the development of movement retraining interventions and potentially improve rehabilitation outcomes for those with FAIS.

Accumulation of Good Intentions: How Individual Practice Guidelines Lead to Polypharmacy in the Treatment of Patients with Polytrauma.

Polytrauma clinical triad (PCT) is the comorbid occurrence of traumatic brain injury (TBI), posttraumatic stress disorder (PTSD), and pain after trauma. No clinical practice guidelines for postacute care of patients with PCT currently exist; instead, clinical practice guidelines have been published for the three conditions (TBI, PTSD, and pain) as distinct clinical entities. Using multiple, individual practice guidelines for a patient with PCT may lead to unintended prescription of multiple and potentially adversely interacting medications (ie, polypharmacy). Polypharmacy, especially that which includes central nervous system-acting medications, may lead to overdose, suicidality, and chronic symptomatology. Current individual guidelines for each condition of PCT do not address how to coordinate care for the polytraumatic diagnosis. The purpose of this Practice Management piece is to describe the unintended consequences of polypharmacy in patients with PCT and to discuss mitigation approaches including rational prescribing, nonpharmacologic alternatives, and interdisciplinary coordination.

Associations Between Movement Impairments and Function, Treatment Recommendations, and Treatment Plans for People With Femoroacetabular Impingement Syndrome.

OBJECTIVE: The purpose of this study was to describe movement impairments for persons with femoroacetabular impingement syndrome and their association with function, treatment recommendations, and treatment plans. METHODS: This report is a secondary, observational analysis of a clinical trial dataset in which participants received an interdisciplinary evaluation from a surgeon and physical therapist. The therapist documented frontal and sagittal plane movement impairments across 6 functional tasks. Associations between number of impairments in each plane and function (33-item International Hip Outcome Tool [iHOT33]) were evaluated using Pearson or Spearman correlations. Joint provider recommendations (physical therapist and surgeon) and participant-reported treatment plans were dichotomized based on the inclusion of physical therapy or not. Logistic regressions were used to examine the effects of (1) iHOT33, total movement impairments, and previous physical therapist treatment on joint provider recommendation and (2) these same variables along with joint provider recommendation on participant treatment plan; prevalence ratios and 95% CIs were reported for significant contributors. RESULTS: Thirty-nine participants demonstrated an average iHOT33 of 35.0 (SD = 19.5) and presented with a median 5 frontal and 3 sagittal plane impairments. More frontal plane impairments were associated with worse iHOT33 scores. Twenty-seven participants received a joint provider recommendation that included physical therapy; no significant contributors to these recommendations were identified. Twenty-four of the 27 participants with a physical therapist recommendation included physical therapy in their treatment plan. Two additional participants did not receive a physical therapist recommendation but included physical therapy in their plan. Joint provider recommendation was the only significant contributor to the participant-reported plan (prevalence ratio = 7.06; 95% CI = 3.25-7.97). CONCLUSION: Persons with femoroacetabular impingement syndrome displayed clinically observable movement impairments that were associated with worse function. Joint provider recommendations strongly influenced participants' treatment plans to pursue physical therapy. IMPACT: Physical therapists contribute new information to surgical examinations regarding movement. Joint recommendations from the physical therapist and the surgeon can influence patients' decisions to pursue physical therapy.

Factors Associated with Initial Interest and Treatment Selection in Patients with Femoroacetabular Impingement Syndrome.

BACKGROUND: Outcomes for operative and nonoperative management of femoroacetabular impingement syndrome (FAIS) are variable. Understanding factors that inform patients' treatment decisions may optimize their outcomes. OBJECTIVE: To identify factors that predict which patients with FAIS proceed to surgery within 90 days of their initial evaluation by an orthopedic surgeon. The study explored potential predictors of surgical intervention, including demographic factors, activity level, symptom duration, previous treatment, hip function, pain, presence of labral tear, and patient interest in surgical and physical therapy (PT) treatment. DESIGN: Prospective cohort. SETTING: Single-site academic medical center. PATIENTS: Seventy-seven individuals with FAIS. INTERVENTION: After evaluation in a hip preservation clinic, participants reported activity level, symptom duration, treatment history, hip function [Hip Outcome Score Activities of Daily Living(HOS-ADL)], pain severity and location, and treatment interests. These variables were evaluated based on univariate analysis for entry into a multiple binomial logistic regression to identify predictors of surgery within 90 days. Adjusted marginal prevalence ratios and 95% confidence interval estimates (PR [95% CI]) were reported (P ≤ .05). MAIN OUTCOME MEASURE(S): Ninety-day treatment (surgery or not). RESULTS: Participants indicated initial interest in surgery (n = 27), PT (n = 22), both (n = 18), or neither (n = 10). Those only interested in PT had lower prevalence of diagnosed labral tear (P < .001) and previous PT for the hip (P < .001). Prevalence of previous injection was higher for those only interested in surgery than for those with any interest in PT (P < .001). Thirty-six of 77 participants (46%) underwent surgery within 90 days. Surgical interest (3.56 [1.57, 5.46]), previous hip injection (3.06 [1.73, 3.89]), younger age (0.95 [0.92, 0.98]), and worse hip function (0.97 [0.95, 0.99]) were significant (P ≤ .02) predictors of surgery. CONCLUSIONS: Treatment interest and history, patient function, and age were significantly related to participants' decision to pursue surgical intervention within 90 days. Patient engagement in the decision-making process should include considerations of patient knowledge of, and experience with, the various treatment options.

Sex-specific sagittal and frontal plane gait mechanics in persons post-hip arthroscopy for femoroacetabular impingement syndrome.

Postoperative gait mechanics in persons with femoroacetabular impingement syndrome (FAIS) remain understudied as a treatment outcome despite observed, yet inconclusive, preoperative gait abnormalities. Females with FAIS demonstrate worse preoperative patient-reported hip function and altered hip mechanics when compared with males; it is unknown whether these sex differences persist postarthroscopy. The purpose of this study was to compare sex-specific gait kinematics between persons at least 1 year postarthroscopy for FAIS and healthy comparisons. General linear models with estimating equations were used to evaluate the effect of (a) limb and sex within each group, and (b) limb and group within each sex for peak sagittal and frontal plane trunk, pelvis, and hip kinematics during stance phase of gait. Analyses were covaried by gait speed. Seventeen females and eight males an average 2.5 years postarthroscopy (1.1-7.2 year) for FAIS were compared with healthy females (n = 7) and males (n = 5). Females in the FAIS group presented with an average of 4.6° more anterior pelvic tilt, and 4.8° less hip extension compared with healthy females (P ≤ .03) and 8.6° less trunk flexion, 4.8° more anterior pelvic tilt, 3.1° more pelvic drop, and 7.5° more hip flexion than males with FAIS (P ≤ .03). Males in the FAIS group presented with 2.9° less pelvic drop, and 3.2° less hip adduction than healthy males. Preoperative gait mechanics were not collected and thus changes in mechanics could not be evaluated. This study is significant to clinicians who treat patients postarthroscopy to consider sex-specific gait impairments.

Physical Therapists and Physicians Evaluate Nonarthritic Hip Disease Differently: Results From a National Survey.

BACKGROUND: Physical therapy and surgery are viable treatment options for nonarthritic hip disease (NAHD). Interdisciplinary collaboration can help patients make informed treatment decisions. Understanding how each provider can contribute is a critical first step in developing collaborative evaluation efforts. OBJECTIVE: The objective of this study was to describe the current evaluation of NAHD by both physical therapists and physicians, and evaluate national use of expert-recommended evaluation guidelines. DESIGN: A national survey study distributed in the United States was implemented to accomplish the objective. METHODS: A survey was distributed to 25,027 potential physical therapist and physician respondents. Respondents detailed their evaluation content for patients with NAHD across the following domains: patient-reported outcomes, patient history, special tests, movement assessment, clinical tests, and imaging. Respondents ranked importance of each domain using a 5-point Likert scale (not important, slightly important, important, very important, or extremely important). Odds ratios (ORs [95% CIs]) were calculated to identify the odds that physical therapists, compared with physicians, would report each evaluation domain as at least very important. Fisher exact tests were performed to identify statistically significant ORs. RESULTS: Nine hundred and fourteen participants (3.6%) completed the survey. Physical therapists were more likely to indicate movement assessment (OR: 4.23 [2.99-6.02]) and patient-reported outcomes (OR: 2.56 [1.67-3.99]) as at least very important for determining a diagnosis and plan of care. Physical therapists had lower odds of rating imaging (OR: 0.09 [0.06-0.14]) and special tests (OR: 0.72 [0.53-0.98]) as at least very important compared with physicians. LIMITATIONS: This survey study did not include many orthopedic surgeons and thus, primarily represents evaluation practices of physical therapists and nonsurgical physicians. CONCLUSIONS: Physical therapists were more likely to consider movement assessment very important for the evaluation of patients with NAHD, whereas physicians were more likely to consider imaging and special testing very important.

Altered gait mechanics are associated with severity of chondropathy after hip arthroscopy for femoroacetabular impingement syndrome.

BACKGROUND: Suboptimal patient-reported function and movement impairments often persist after hip arthroscopy for femoroacetabular impingement syndrome (FAIS). Individuals with FAIS with preoperative cartilage pathology (ie. chondropathy) demonstrate distinct movement patterns and have worse post-operative outcomes. It is unknown whether the presence of chondropathy after surgery negatively affects movement and function. RESEARCH QUESTION: Do sagittal plane gait mechanics differ based on chondropathy severity following arthroscopy for FAIS? METHODS: A cross-sectional walking gait analysis was performed for 25 participants post-arthroscopy (2.48 ±â€¯1.38y) and 12 healthy controls (HCs). Peak total support moment (TSM) and relative contributions of the hip, knee, and ankle were calculated during loading response. The Hip Osteoarthritis MRI Scoring System was used to categorize the FAIS group into no-mild or moderate-severe chondropathy groups based on 3 T magnetic resonance imaging of their surgical hip. The interactions of group by limb were evaluated for kinetic variables, covaried by gait speed. RESULTS: Groups did not differ based on age, BMI and sex distribution (P ≥ 0.14). 13 participants with FAIS presented with moderate-severe chondropathy and 12 presented with no-mild chondropathy. Participants with moderate-severe chondropathy walked significantly slower than both other groups (P = 0.006) and demonstrated lower peak TSM than those with no-mild chondropathy (P = 0.002). Participants with no-mild chondropathy demonstrated lower hip (61.5 %) and greater ankle (17.7 %) contributions to the TSM on the involved limb compared to the moderate-severe group (hip:73.4 %, P = 0.07; ankle:10.5 %, P = 0.007). SIGNIFICANCE: Slower gait speed alone did not explain the lower TSM strategy in participants with moderate-severe chondropathy. Interestingly, the joint contribution strategy of this group was not different than HCs. Participants with no-mild chondropathy demonstrated a TSM strategy that shifted the demand away from their hip and toward their ankle. Given the small sample size, and large variability in joint strategies, future work needs to examine whether these alterations in gait strategy, with or without advanced chondropathy, impact patient function.
