Objectives: Most patients seen in physical therapy (PT) clinics for low back pain (LBP) are treated for chronic low back pain (CLBP), yet PT interventions suggest minimal effectiveness. The Cochrane Back Review Group proposed 'Holy Grail' questions, one being: 'What are the most important (preventable) predictors of chronicity' for patients with LBP? Subsequently, prognostic factors influencing outcomes for CLBP have been described, however results remain conflicting due to methodological weaknesses.

Methods: This retrospective observational cohort study examined prognostic risk factors for PT outcomes in CLBP treatment using a sub-type of AI. Bootstrap random forest supervised machine learning analysis was employed to identify the outcomes-associated variables.

Results: The top variables identified as predictive were: FOTO™ predicted functional status (FS) change score; FOTO™ predicted number of visits; initial FS score, age; history of jogging/walking, obesity, and previous treatments; provider education level; medication use; gender.

Conclusion: This article presents how AI can be used to predict risk prognostic factors in healthcare research. Improving predictive accuracy helps clinicians predict outcomes and determine most appropriate plans of care and may impact research attrition rates.

The historical development of manual therapy is an area of ongoing debate impacting clinical practice, education, and practice regulations. Primary professions utilizing manual therapy include chiropractic, manual medicine, osteopathy, and physiotherapy. A survey was developed to explore perceptions, experiences, and opinions across professions, and was disseminated globally. It was completed by 194 individuals. Results demonstrated this topic is of significance with over 80% reporting that knowledge of historical development informs professional identity. Of the respondents, 64% had over 20 years professional experience. Student participation was low (<1%). Over 95% acknowledged an ancient basis for manual therapy, with 67% emphasizing bonesetter contributions. North America was reported as the primary area for the development of modern manual therapies by all except physiotherapy, which identified Northern Europe. Osteopathy's impact on current practice was recognized, though each profession ranked its own impact highest. Of respondents, 85% agreed there was conflict between professions over history. Thematic elements identified a shift for respondents from their initial education to a more nuanced understanding of the history over time, and an appreciation that there is not one profession that owns or developed manual therapy. Practice limitations were identified, as 19% of respondents reported limitations due to inaccurate historical understanding. This study highlights a lack of historical knowledge and its potential benefits for practice, education, regulation and interprofessional relations if recaptured. (the abstract was rewritten per reviewer comments to reformat).

Background: Perspectives on the historical genesis of manual therapy for chiropractic, manual medicine, osteopathy, and physiotherapy are limited.

Objective: This study sought to identify themes and narratives related to the genesis of manual therapy; the potential of a common root for manual therapy in 19^th century Northern Europe; and the potential impact of a current 'broken history' for manual therapy.

Methods: An exploratory phenomenological approach was utilized, based upon structured one-hour interviews of 21 professionals across four professions who had previously completed a survey on the historical genesis of manual therapy.

Results: Descriptive and hermeneutic themes were developed based upon the lived experience of individuals relating to interview questions and a presented historical narrative. Support for a common genesis in Northern Europe was present within physiotherapists, but for all other professions North America was primary. Multiple themes and quotes of significance were developed from the study, including the importance of history within professional identity. An archetypal analysis was completed to answer specific assumptions related to the historical genesis of manual therapy including points of genesis for manual therapy and scientific necessity within manual therapy.

Conclusion: The findings of this study provide new perspectives to consider on the value, criticality, and impact of manual therapy, and its history's for the four professions in practice, education, and regulations.

Objectives: We aimed to determine the effect duration of a talocrural mobilization on individuals with restricted dorsiflexion during a static weight bearing lunge test (WBLT) and dynamic 3D motion capture-based peak ankle dorsiflexion during a forward step down (FSD) task. Secondarily, we aimed to correlate any immediate changes in ankle mobility with concurrent changes in proximal joint kinematics during the FSD post-mobilization.

Methods: Seventy-six individuals were screened for dorsiflexion restriction, of which 26 (15 females, 22.3 ± 2.2 years old, body mass index 25.2 ± 2.9 kg/m2) qualified with a WBLT of ≤ 35° on at least one limb. A baseline WBLT measure and 3D motion capture of 5 consecutive FSD repetitions on a 6-inch box were obtained. Participants then viewed an instructional video of a talocrural joint self-mobilization using a resistance band. WBLT and FSD were collected again immediately post-mobilization and at 5-min intervals for 60 min or until the WBLT returned to baseline for 2 consecutive measures.

Results: WBLT dorsiflexion showed a mean increase of 6.5 degrees (p < 0.001) post-mobilization. The effect faded over time and no longer differed from baseline 25 min post-mobilization (p = 0.964). Dynamic peak ankle dorsiflexion did not change post-mobilization at any time point (p ≥ 0.546). No 3D kinematic time-course changes were observed at the hip or knee. However, immediate raw alterations in dorsiflexion correlated with alterations for hip and knee flexion.

Discussion/conclusion: A talocrural joint mobilization increased static dorsiflexion per the WBLT for a 20-25-min period with regression to baseline. However, increased dynamic ankle dorsiflexion was not observed during the FSD task. Improved mobility alone does not appear to change movement patterns. Clinicians should be aware of both effect duration and the potential need for task-specific training to better facilitate dynamic utilization of increased mobility.

Objective: To determine the effectiveness of the McKenzie Method compared to any conservative interventions on pain and disability in patients with chronic low back pain (LBP) with directional preference (DP).

Methods: We searched six electronic databases up to September 2022. Eligible randomized controlled trials were those assessing the McKenzie Method delivered by credentialed therapists for chronic LBP with DP. Two reviewers independently selected studies, extracted data, assessed risk of bias with the revised Cochrane Risk of Bias 2.0 tool and certainty of evidence with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework.

Results: Five trials (n = 743) were included. There was low-certainty evidence that the McKenzie Method, compared to all other interventions combined, produced clinically important reductions in short-term pain (mean difference [MD] -1.11 points on a 10-point scale; 95% CI -1.83 to -0.40) and in intermediate-term disability (standardized mean difference [SMD] -0.53; 95% CI -0.97 to -0.09). Low-to-moderate certainty evidence showed that the McKenzie Method also resulted in clinically important improvements in short-term pain (MD -1.53; 95% CI -2.51 to -0.54) and disability (SMD -0.50; 95% CI -0.74 to -0.25) when compared specifically to other exercise approaches, and in intermediate-term pain (MD -2.10; 95% CI -2.94 to -1.26) and disability (SMD -1.01; 95% CI -1.58 to -0.43) as well as long-term disability (SMD -0,59; 95% CI -1.14 to -0.03) when compared to minimal intervention. Low-certainty evidence showed usually small, clinically unimportant effects in comparison to manual therapy.

Conclusion: We found low-to-moderate certainty evidence that the McKenzie Method was superior to all other interventions combined for up to 6 months for pain and up to 12 months for disability, with clinically important differences versus exercise in the short term and versus minimal interventions in the intermediate term. The only clinically important long-term effect was on disability compared to minimal intervention.

Background: The LBP-related attitudes and beliefs of clinicians may impact the experience of patients by influencing clinician decision-making and by shaping the attitudes, beliefs, and actions of patients. The purpose of this study was to identify the specific LBP-related attitudes and beliefs of US-based physical therapists and determine if those beliefs correlate with clinical decision-making.

Methods: An electronic survey was sent to US-based physical therapists. Attitudes and beliefs were measured using the Health Care Providers' Pain and Impairment Relationship Scale (HC-PAIRS) and the Pain and Impairment Relationship Scale for Physiotherapists (PABS-PT). The survey also included 2 patient vignettes that collected information about clinical decision-making.

Results: Complete survey responses were recorded from 420 physical therapists. Eleven of the 27 attitude and beliefs questions were answered in a more biomedically oriented way by at least 20% of respondents. Physical therapist low back pain-related attitudes and beliefs were associated with activity and management strategies for both vignettes in the expected direction. Higher scores on HC-PAIRS and PABS-BM were associated with more restrictive work and activity recommendations, lower-intensity exercise choices, biomechanical rationale for manual therapy and motor control exercises, pathoanatomical-focused education, and use of modalities.

Conclusion: Some physical therapists hold biomedically oriented beliefs about the connection between pain and physical activity. Clinician beliefs were associated with activity and work recommendations, and treatment choices. Physical therapists with more biomedically oriented beliefs were more likely to limit physical activity and work, and less likely to incorporate psychologically informed interventions.

Introduction: Reflective clinical reasoning (CR) is believed to play a crucial role in achieving an efficient therapy process, supported by evidence-based approaches that improve patient outcomes. The aim of this study was to evaluate the CR process of German manual therapists (MTs) using the CR skills of Dutch MTs as a reference.

Methods: This cross-sectional study evaluated the CR process and diagnostic ability of German MTs. Dutch MTs served as the reference standard due to their experience with direct access. The CR skills were assessed using the Diagnostic Thinking Inventory (DTI), a questionnaire measuring diagnostic competence. Descriptive and inferential statistics were conducted to compare the groups. Subgroup analyses were performed to analyze the influence of work experience (in years) and the level of education on CR.

Results: 396 manual therapists (229 German and 167 Dutch) completed the DTI. Dutch MTs revealed higher DTI sum-scores compared to German MTs (p < .001; Cohen´s d = .41). Subgroup analyses regarding professional education revealed no significant differences in DTI sum-scores within German MTs and between both groups. In the subgroup analyses regarding professional experience, differences of moderate effect size were reached between German and Dutch novice MTs (in favor of Dutch novice MTs; p = .001; Cohen´s d = .62), and between German novice MTs and experienced German MTs (in favor of experienced German MTs; p < .001; Cohen´s d = .6).

Conclusion: The results suggest that academically educated German and Dutch MTs as well as experienced German and Dutch MTs are similar in terms of their hypothetical-deductive CR skills. In turn, German novice MTs seem to use hypothetical-deductive processing to a lesser extent compared to Dutch novice MTs and experienced German MTs, which in turn may support the hypothesis that the level of professional experience and education has a significant impact on the development of hypothetical-deductive CR skills.
