The Orthopaedic Section of the American Physical Therapy Association presents this second set of clinical practice guidelines on neck pain, linked to the International Classification of Functioning, Disability, and Health (ICF). The purpose of these practice guidelines is to describe evidence-based orthopaedic physical therapy clinical practice and provide recommendations for (1) examination and diagnostic classification based on body functions and body structures, activity limitations, and participation restrictions, (2) prognosis, (3) interventions provided by physical therapists, and (4) assessment of outcome for common musculoskeletal disorders.

SYNOPSIS: The process of evidence-based practice (EBP) guides clinicians in the integration of individual clinical expertise, patient values and expectations, and the best available evidence. Becoming proficient with this process takes time and consistent practice, but should ultimately lead to improved patient outcomes. The EBP process entails 5 steps: (1) formulating an appropriate question, (2) performing an efficient literature search, (3) critically appraising the best available evidence, (4) applying the best evidence to clinical practice, and (5) assessing outcomes of care. This second commentary in a 2-part series will review principles relating to steps 3 through 5 of this 5-step model. The purpose of this commentary is to provide a perspective to assist clinicians in interpreting results, applying the evidence to patient care, and evaluating proficiency with EBP skills in studies of interventions for orthopaedic and sports physical therapy.

For physical therapists to justify our services for patients with musculoskeletal problems, we need to achieve clinical outcomes superior to those associated with natural history or due to the passage of time. If a patient's presentation is unclear or if the response to intervention is less favorable than expected, practical application of the regional-interdependence model may add clarity to the patient's clinical picture and guide subsequent interventions. Likewise, further investigation of the regional-interdependence concept in a systematic fashion may add clarity to the nature of many musculoskeletal problems and guide subsequent decision making in clinical care.

The diagnosis and nonoperative management of hip disorders are important clinical issues. Physical therapists can provide an alternative to surgical and pharmacological solutions for patients with lower quarter musculoskeletal complaints with noninvasive, low-risk interventions that are effective for reducing pain and disability. These interventions have none of the health risks associated with medications, surgery, and other invasive treatment options. Although effective low-risk physical therapy interventions exist for these patients, the real question is whether patients know about physical therapy and whether they are afforded an opportunity to access this type of care. Equally important is whether we physical therapists are adequately delivering it.

Study Design: Secondary analysis of a randomized trial. Objectives: To examine the influence of experience and specialty certification on outcomes for patients with low back pain receiving a standardized manipulation or stabilization exercise intervention program. Background: Little research has examined the impact of therapist-related factors on the outcomes of clinical care for patients with low back pain. It is assumed that therapists with more clinical experience or specialty certification will achieve better clinical outcomes; however, few studies have examined this hypothesis. Methods and Measures:One hundred thirty-one participants in a randomized trial were included (70 randomized to receive manipulation, 61 stabilization). All subjects completed an Oswestry Disability Questionnaire at baseline, and after 1 and 4 weeks of treatment. Therapists were categorized based on total years of experience, years of experience with manual therapy, and specialty certification status. Two-way repeated-measures analyses of covariance were performed within each intervention group to examine the effects of the therapist characteristics on outcomes. Hierarchical linear regression models were used to examine the relative effects of therapist characteristics and intervention on clinical outcomes. Results: Thirteen therapists participated (average 6.0 years of experience [standard deviation, 4.0], 4 (30.8%) with specialty certification). A significant interaction between time and specialty certification status (P = .04) was detected for subjects receiving the manipulation intervention. No significant interactions were detected in the stabilization group. The regression models found that the intervention group significantly contributed to explaining clinical outcomes, but that therapist characteristics did not. Conclusions: With the standardized protocol utilized in this study, it appears that the therapist-related factors of increased experience and specialty certification status do not result in an improvement in patients’ disability associated with low back pain.

Study Design: One group pretest-posttest exploratory design. Objectives: Primary purposes of this study were to examine the short-term effect of hip mobilizations on pain and range of motion (ROM) measurements in patients with knee osteoarthritis (OA) and to determine the prevalence of painful hip and squat test findings in both patients with knee OA and asymptomatic subjects. The secondary purposes were to assess intrarater reliability and to determine whether fewer subjects experienced painful test findings following hip mobilization. Background: Conservative intervention, including manual physical therapy applied to the lower extremity, has been shown to reduce impairments associated with knee OA. Methods and Measures: One rater pair administered 4 clinical hip tests to 22 patients with knee OA (mean age, 61.2 years; SD, 6.1 years) and 17 subjects without lower extremity symptoms or known pathology (mean age, 64.0 years; SD, 7.9 years). Intrarater reliability was examined for each clinical test. Patients with knee OA and painful-hip and squat test findings received hip mobilizations. Pain and ROM responses for each test were dependent variables. Results: Intraclass correlation coefficients for all tests were greater than 0.87. Composite and individual test pain scores and ROM scores improved significantly following hip mobilization. All clinical test findings were more frequent in the group with knee OA, except for those of the FABER test, and the number of subjects with painful test findings following hip mobilization was reduced for all tests except the hip flexion test. Conclusions: Patients experienced increases in ROM, decreased pain, and fewer subjects had painful test findings immediately following a single session of hip mobilizations. Examination and intervention of the hip may be indicated in patients with knee OA.

Design: Retrospective ex-post facto design. Objectives: To retrospectively review the management of patients with lateral epicondylalgia, and to compare self-reported outcomes to assess the potential benefit of manual physical therapy to the cervical spine. Background: It has been postulated that dysfunction of the cervical spine may contribute to the symptoms associated with lateral epicondylalgia; however, the literature assessing the effectiveness of manual physical therapy to the cervicothoracic region in this patient population has been inconclusive. Documentation and analysis of outcomes of management strategies focusing on the cervical spine may lead to determining the most effective and efficient clinical practices. Methods and Measures: Of the 213 charts reviewed, 112 satisfied inclusion-exclusion criteria and were divided into 2 groups: those who received treatment solely directed at the elbow (local management [LM]), or those who received treatment directed at the elbow and cervical manual therapy (LM+C). Telephone follow-up interviews were used to determine the number of successful outcomes. Percentages of successful outcomes in each group were compared using chi-square analysis. An independent samples t test was used to compare the total number of visits per group. Results: Sixty-one of the 112 patients were in the LM group, while 51 received LM+C. Seventy-five percent of the patients available for follow-up in the LM group and 80% in the LM+C group reported a successful outcome. Patients in the LM group received a greater number of visits (mean, 9.7; SD, 2.4) than patients in the LM+C group (mean, 5.6; SD, 1.7; P<.01). Conclusions: The results of this retrospective review suggest that most patients had successful outcomes regardless of the inclusion of manual therapy interventions to the cervical spine. The LM+C group achieved the successful long-term outcome in significantly fewer visits.
