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.

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.

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.

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.

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.

A randomized controlled trial protocol for an interdisciplinary evaluation of non-arthritic hip disease.

BACKGROUND: Non-arthritic hip disease (NAHD) is a clinical condition often accompanied by painful movement. Current literature is lacking regarding how movement abnormalities are evaluated and treated in this population, which may be key to identifying which patients may respond to non-operative versus operative treatment. Combining the expertise of a hip arthroscopist and physical therapist may better inform treatment decisions for persons with NAHD. The primary objective of this study is to identify the extent to which an interdisciplinary evaluation between a physical therapist and surgeon influences treatment decisions of persons presenting to a hip preservation clinic. RATIONALE FOR STUDY DESIGN: A prospective, randomized controlled trial provides the ability to identify cause and effect of this new evaluation type. METHODS: Ninety-six adults with unilateral, NAHD presenting to a hip preservation clinic for initial evaluation will be randomized to receive either a standard evaluation with a surgeon or an interdisciplinary evaluation by a physical therapist and surgeon. Regardless of group, the surgeon conducts a standard-care examination. For participants in the interdisciplinary group, the physical therapist conducts an assessment of 6 postures and movements to identify asymmetrical, abnormal, or painful strategies. Treatment selection(s) and decisional conflict will be compared between groups after the evaluations. DISCUSSION: Persons with NAHD may experience considerable decisional conflict because of prolonged duration of symptoms and minimal evidence to compare operative and non-operative treatment for this population. The findings of this study have the potential to improve patient experience and produce more informed and supported treatment decisions for persons considering surgical treatment for NAHD.

Return to Sport Rates in Physically Active Individuals 6 Months After Arthroscopy for Femoroacetabular Impingement Syndrome.

CONTEXT: Six months is the expected time frame to return to sport (RTS) after hip arthroscopy for femoroacetabular impingement syndrome (FAIS). OBJECTIVE: The primary aims of this study were to (1) report the RTS rate of physically active individuals 6 months after arthroscopic surgery for FAIS and (2) compare the self-reported hip function between those who were able to RTS against those who had not. DESIGN: Cohort study. SETTING: The Ohio State University Wexner Medical Center. PATIENTS: A total of 42 physically active individuals scheduled for hip arthroscopy for FAIS. MAIN OUTCOME MEASURES: Self-reported function, including preinjury and current activity levels and ability to participate in sport, were collected on 42 individuals with FAIS prior to surgery and at 6-month follow-up. Participants were allocated into 2 groups based on self-reported RTS status at 6-month follow-up. Separate 2-way analyses of variance were used to test the interaction of groups (those who did/did not RTS). Main effects were reported in the absence of statistically significant interactions (P ≤ .05). RESULTS: Altogether, 28 of 42 participants (66%) returned for 6-month follow-up; 5 of the 14 participants (35.7%) lost to follow-up underwent contralateral hip surgery within the study time frame. At the 6-month follow-up, 16 of the remaining 28 participants (57.1%) reported that they had returned to sport, 5 of whom returned at their prior level of participation. There was no statistically significant interaction of group and time for either hip outcome score subscale (P ≥ .20). Self-reported hip function improved over time, regardless of group (P ≤ .001). Participants in the yRTS group demonstrated higher hip outcome score-sport scores than did the nRTS group, regardless of time (P = .04). CONCLUSIONS: Though just over half of participants returned to sport 6 months after hip arthroscopy for FAIS, only 18% returned to their previous level of sports participation. Participants who returned to sport reported better function than those who did not, but self-reported hip function improved over time regardless of group. The most commonly reported reasons for not returning to sport were weakness (69.6%), fear (65.2%), and pain (56.5%).

Intra- and inter-rater reliability of the selective functional movement assessment (sfma).

PURPOSE/BACKGROUND: The Selective Functional Movement Assessment (SFMA) is a clinical assessment system designed to identify musculoskeletal dysfunction by evaluation of fundamental movements for limitations or symptom provocation. The purpose of this study was to determine the intra- and inter-rater reliability of the ten fundamental movement patterns of the SFMA in a healthy population using the SFMA categorical and criterion checklist scoring tools. METHODS: 35 healthy subjects (22.9 years +/- 1.9) were recorded with two digital video cameras (1-frontal view/1-sagittal view) while they performed the ten fundamental movements patterns that comprise the SFMA. Evaluators with varying experience with the SFMA (rater A, > 100 hours; rater B, 25 hours; and rater C, 16 hours) and not present at the initial data collection evaluated each video using categorical and criterion checklist scoring tools. Evaluators repeated this process at least one week later. The evaluators' composite results were compared between and within raters using the kappa coefficient and ICC's for categorical scoring and criterion checklist scoring, respectively. RESULTS: Substantial to almost perfect intra-rater reliability of the SFMA (kappa, % agreement) was observed for all raters using the categorical scoring tool (rater A: .83, .91; rater B: .78, .88; and rater C: .72, .85). The criterion checklist scoring tool yielded intra-rater ICCs (3,1; 95% confidence interval) ranging from good to poor with rater A demonstrating the highest reliability (ICC [SEM]) (.52 [2.36]) and rater C the lowest reliability (.26 [3.42]). Inter-rater reliability of the categorical scoring tool was slight to substantial (.41-.61, .69-.79) while the criterion checklist tool (ICC 2,1) demonstrated unacceptable inter-rater reliability when assessed in all raters together (.43 [2.7]). CONCLUSIONS: As hypothesized, intra-and inter-rater reliability of categorical scoring and criterion checklist scoring of the ten fundamental movements of the SFMA was higher in raters with greater experience.
