OBJECTIVE: To describe the variation in outcomes and number of visits before and after implementing a care guideline for total knee arthroplasty (TKA) rehabilitation. DESIGN: Nonrandomized intervention study. METHODS: We compared 2558 patients with TKA who received care that was not standardized (non-care guideline [NCG] group) to 9797 patients with TKA who received care according to the care guideline (CG). We fit 2 Bayesian hierarchical linear regression models using the Knee Outcome Survey - Activities of Daily Living (KOS-ADL) change score and number of physical therapy (PT) visits as the response variables, controlling for relevant predictor variables. We also compared the ratio of the standard deviations of the KOS-ADL change scores and the number of PT visits within and between clinics. RESULTS: The overall estimated mean improvement in KOS-ADL change score was 23.0 points (95% confidence interval [CI]: 20.3, 25.7) in the NCG group and 28.7 points (95% CI: 27.5, 29.7) in the CG group; the mean difference was 5.6 (2.7-8.6). Mean KOS-ADL change scores were higher in the CG group than the NCG group in every clinic, although only 8 clinics improved significantly. The number of PT visits did not change meaningfully (NCG: mean, 10.7 [95% CI: 9.9, 11.5]; CG: mean, 10.5 [95% CI: 9.9, 10.9]). Variation in KOS-ADL change score decreased by 4% within clinics (CG-NCG ratio: 0.96 [95% CI: 0.93, 0.99]) and 63% between clinics (CG-NCG ratio: 0.37 [95% CI: 0.21, 0.62]). Variation in number of visits decreased by 7% within clinics (CG-NCG ratio: 0.93 [95% CI: 0.90, 0.96]) and 19% between clinics (CG-NCG ratio: 0.81 [95% CI: 0.39, 1.49]). CONCLUSION: Implementing a care guideline for TKA rehabilitation may improve outcomes and reduce unwarranted variation in practice within clinics and especially between clinics within a large health care system.

OBJECTIVE: To describe the application and examine the influence of a continuous quality improvement intervention, which had a goal of standardizing care to reduce the proportion of patients who do not have a meaningful improvement in patient-reported outcomes following total knee arthroplasty (TKA). DESIGN: Continuous quality improvement. METHODS: A physical therapy (PT) care guideline was initiated in 2013 for patients following TKA. The Knee Outcome Survey - Activities of Daily Living (KOS-ADL) was measured at every visit, and scores were extracted from a clinical outcomes database to calculate the proportion of patients who did not achieve a minimal clinically important difference. Based on logistic regression analysis, we compared the proportion of patients who did not progress on the KOS-ADL in a non-care guideline group (2008-2012) to a care guideline (CG) group (2014-2019). RESULTS: This study included 12 355 patients (aged 18-92 years) following TKA incurring at least 3 PT visits from 2008 to 2019. The percentage of patients who did not progress in the non-care guideline group was 25.8% and in the care guideline group 14.3% (P<0.001). The relationship between care guideline adherence and lack of progression on the KOS-ADL was statistically significant, X 2 ( df = 1) = 148.7, P<.001. CONCLUSION: The percentage of patients who did not achieve meaningful progress on the KOS-ADL declined significantly in the 6 years after implementing a TKA care guideline without an increase in the number of clinical visits. The standardized care guideline was associated with meaningful improvements for patients following TKA when applied in conjunction with PT access to outcome data, feedback through audits, performance goals, and financial incentives.

Study Design: Randomized clinical trial. Background The recommended initial management strategy for patients with low back pain and signs of nerve root compression is conservative treatment, but there is little evidence to guide the most appropriate management strategy. Preliminary research suggests that a treatment protocol of mechanical traction and extension-oriented exercises may be effective, particularly in a specific subgroup of patients., Objective: To examine the effectiveness of mechanical traction in patients with lumbar nerve root compression and within a predefined subgroup., Methods: One hundred twenty patients with low back pain with nerve root compression were recruited from physical therapy clinics. Using predefined subgrouping criteria, patients were stratified at baseline and randomized to receive an extension-oriented treatment approach with or without the addition of mechanical traction. During a 6-week period, patients received up to 12 treatment visits. Primary outcomes of pain and disability were collected at 6 weeks, 6 months, and 1 year by assessors blinded to group allocation. Outcomes were examined using linear mixed-model analyses examining change over time by treatment and the interaction between treatment and subgrouping status., Results: The mean ± SD age of participants was 41.1 ± 11.3 years, median duration of symptoms was 62 days, and 57% were male. No significant differences in disability or pain outcomes were noted between treatment groups at any time point, nor was any interaction found between subgroup status and treatment., Conclusion: Patients with lumbar nerve root compression presenting for physical therapy can expect significant changes in disability and pain over a 6-week treatment period. There is no evidence that mechanical lumbar traction in combination with an extension-oriented treatment is superior to extension-oriented exercises alone in the management of these patients or within a predefined subgroup of patients. The study protocol was registered with ClinicalTrials.gov (NCT00942227). Level of Evidence Therapy, level 2b.

Study Design: Randomized clinical trial., Objectives: To examine the effectiveness of cervical traction in addition to exercise for specific subgroups of patients with neck pain., Background: Cervical traction is frequently used, but its effectiveness has not been adequately examined. Existing studies have failed to target patients most likely to respond. Traction is typically recommended for patients with cervical radiculopathy. A prediction rule has been described to identify a narrower subgroup of patients likely to respond to cervical traction., Methods: Patients with neck pain and signs of radiculopathy were randomized to 4 weeks of treatment with exercise, exercise with mechanical traction, or exercise with over-door traction. Baseline assessment included subgrouping-rule status. The primary outcome measure (Neck Disability Index, scored 0-100) and secondary outcome measure (neck and arm pain intensity) were assessed at 4 weeks, 6 months, and 12 months after enrollment. The primary analyses examined 2-way treatment-by-time interactions. Secondary analyses examined validity of the subgrouping rule by adding 3-way interactions., Results: Eighty-six patients (53.5% female; mean age, 46.9 years) were enrolled in the study. Intention-to-treat analysis found lower Neck Disability Index scores at 6 months in the mechanical traction group compared to the exercise group (mean difference between groups, 13.3; 95% confidence interval: 5.6, 21.0) and over-door traction group (mean difference between groups, 8.1; 95% confidence interval: 0.8, 15.3), and at 12 months in the mechanical traction group compared to the exercise group (mean difference between groups, 9.8; 95% confidence interval: 0.2, 19.4). Secondary outcomes favored mechanical traction at several time points. The validity of the subgrouping rule was supported on the Neck Disability Index at the 6-month time point only., Conclusion: Adding mechanical traction to exercise for patients with cervical radiculopathy resulted in lower disability and pain, particularly at long-term follow-ups. The study protocol was registered at http://clinicaltrials.gov (NCT00979108).

Study Design: Retrospective cohort study., Objectives: To describe the clinical outcomes following outpatient physical therapy for postoperative rehabilitation in 4 categories of shoulder surgery. Furthermore, we sought to determine if differences in outcomes between genders existed., Background: Improving the quality of care for patients following shoulder surgery requires an understanding of the clinical outcomes resulting from current clinical practice., Methods: This study included 856 patients (43.7% female; mean +/- SD age, 51.8 +/- 14.2 years) who received outpatient physical therapy following shoulder surgery. Standardized methods for classification of patients to type of shoulder surgery and collection of outcome variables were used. Data were gathered from 57 therapists working in 12 clinics. Patients included had been classified into 1 of 4 surgical categories: repair of a unidirectional instability, rotator cuff repair, rotator cuff repair with a subacromial decompression, or subacromial decompression alone. Descriptive statistics were calculated for baseline characteristics of patients in each surgical category. For all patients, scores on the Disability of the Arm Shoulder and Hand (DASH) questionnaire and a numeric pain rating scale (NPRS) were obtained at the initial and final physical therapy visits, and the change between visits was calculated. Data on number of physical therapy sessions and length of stay (LOS) were collected. For each surgical category, independent-samples t tests were used to determine differences between genders for each initial and final clinical outcome of pain and disability, change scores, utilization of visits, and LOS. The percentage of patients who achieved a minimal clinically important difference (MCID) on the DASH was also determined for each surgical group. For each gender in each surgical category, paired t tests were used to determine if patients achieved significant change in pain and disability., Results: Means for each clinical outcome for the initial and final pain and disability scores, change scores, and the percentage of patients that achieved an MCID are provided. Significant differences were observed between genders for clinical outcomes. In the group treated with unilateral instability repair, women reported significantly greater initial disability than men, and their DASH change scores were significantly greater. In the group that had rotator cuff repairs, women reported significantly greater disability initially and at the final follow-up. In the group that had rotator cuff repairs combined with subacrominal decompression, women reported significantly greater disability initially and greater change in DASH scores. Females also reported greater change in their pain scores than males (P<.05). There were no significant differences between men and women in the subacromial decompression group (P<.05). There were no significant differences between genders for number of physical therapy visits or LOS. Men and women in each surgical category achieved clinically meaningful and statistically significant improvement for pain and disability during treatments (P<.01). Greater than 75% of patients achieved an MCID (15 points) on the DASH score in each surgical category (range, 75.6%-94.5%)., Conclusions: Differences were observed between men and women in 4 postoperative surgical categories in each of the clinical outcomes but not for number of physical therapy visits or LOS. Statistically significant and clinically meaningful pain and disability improvements were reported for each gender within each shoulder category. Results from this study may help therapists estimate the prognosis of males and females receiving nonstandardized postoperative physical therapy in 4 different shoulder surgical categories., Level of Evidence: Therapy, level 2b.

Study Design: Secondary analysis of pooled data from 3 randomized trials., Objective: This study investigated sex differences in response to physical therapy intervention for acute low back pain., Background: Sex differences in experimental pain sensitivity have been consistently described in the literature. However, clinical consequences of these sex differences have not been widely reported., Methods and Measures: Subjects (n=165) were participants in 3 randomized trials of physical therapy interventions from outpatient physical therapy clinics in the general and military communities. Subjects were randomly assigned spinal manipulation with range-of-motion exercise, lumbar stabilization exercise, or directional-preference exercise. Outcomes were measured at 4 weeks through self-report of pain intensity and pain-related disability. Sex differences were investigated with independent t tests (baseline data), 2 x 3 analysis of variance (4-week reductions in pain and pain-related disability), and regression models (predictors of outcome)., Results: Men and women had similar reductions of pain intensity (raw mean difference, 0.5; 95% Cl, -1.4 to 0.4) and pain-related disability (raw mean difference, 5.3; 95% CI, -0.1 to 10.7) over 4 weeks. Baseline pain intensity, duration of symptoms, and baseline pain-related disability significantly predicted change in pain intensity for women (r2 = 26%, P < .01). Baseline pain intensity and stabilization exercise predicted change in pain intensity for men (r2 = 33%, P<.01). Baseline pain-related disability, duration of pain, and pain intensity predicted change in disability for women (r2 = 24%, P < .01). Baseline pain-related disability, fear-avoidance beliefs, stabilization exercise, and leg pain predicted change in disability for men (r2 = 32%, P < .01)., Conclusion: For patients with acute low back pain, men and women had similar physical therapy outcomes for reductions in pain intensity and pain-related disability. However, men and women had different factors that predicted treatment outcome.
