Development of a clinical prediction rule for guiding treatment of a subgroup of patients with neck pain: use of thoracic spine manipulation, exercise, and patient education.

BACKGROUND AND PURPOSE: To date, no studies have investigated the predictive validity of variables from the initial examination to identify patients with neck pain who are likely to benefit from thoracic spine thrust manipulation. The purpose of this study was to develop a clinical prediction rule (CPR) to identify patients with neck pain who are likely to experience early success from thoracic spine thrust manipulation. SUBJECTS: This was a prospective, cohort study of patients with mechanical neck pain who were referred for physical therapy. METHODS: Subjects underwent a standardized examination and then a series of thoracic spine thrust manipulation techniques. They were classified as having experienced a successful outcome at the second and third sessions based on their perceived recovery. Potential predictor variables were entered into a stepwise logistic regression model to determine the most accurate set of variables for prediction of treatment success. RESULTS: Data for 78 subjects were included in the data analysis, of which 42 had a successful outcome. A CPR with 6 variables was identified. If 3 of the 6 variables (positive likelihood ratio=5.5) were present, the chance of experiencing a successful outcome improved from 54% to 86%. DISCUSSION AND CONCLUSION: The CPR provides the ability to a priori identify patients with neck pain who are likely to experience early success with thoracic spine thrust manipulation. However, future studies are necessary to validate the rule.

A comparison between two physical therapy treatment programs for patients with lumbar spinal stenosis: a randomized clinical trial.

STUDY DESIGN: Multicenter randomized, controlled trial. OBJECTIVE: To compare two physical therapy programs for patients with lumbar spinal stenosis. SUMMARY OF BACKGROUND DATA: Scant evidence exists regarding effectiveness of nonsurgical management programs for lumbar spinal stenosis. METHODS: Fifty-eight patients with lumbar spinal stenosis were randomized to one of two 6-week physical therapy programs. One program included manual physical therapy, body weight supported treadmill walking, and exercise (Manual Physical Therapy, Exercise, and Walking Group), while the other included lumbar flexion exercises, a treadmill walking program, and subtherapeutic ultrasound (Flexion Exercise and Walking Group). Perceived recovery was assessed with a global rating of change scale. Secondary outcomes included: Oswestry, a numerical pain rating scale, a measure of satisfaction, and a treadmill test. Testing occurred at baseline, 6 weeks, and 1 year. Perceived recovery, pain, and other healthcare resources used were collected with a long-term follow-up questionnaire. RESULTS: A greater proportion of patients in the manual physical therapy, exercise, and walking group reported recovery at 6 weeks compared with the flexion exercise and walking group (P = 0.0015), with a number needed to treat for perceived recovery of 2.6 (confidence interval, 1.8-7.8). At 1 year, 62% and 41% of the manual therapy, exercise, and walking group and the flexion exercise and walking group, respectively, still met the threshold for recovery. Improvements in disability, satisfaction, and treadmill walking tests favored the manual physical therapy, exercise, and walking group at all follow-up points. CONCLUSIONS: Patients with lumbar spinal stenosis can benefit from physical therapy. Additional gains may be realized with the inclusion of manual physical therapy interventions, exercise, and a progressive body-weight supported treadmill walking program.

The reliability and construct validity of the Neck Disability Index and patient specific functional scale in patients with cervical radiculopathy.

STUDY DESIGN: Cohort study of patients with cervical radiculopathy undergoing physical therapy. OBJECTIVES: Examine the test-retest reliability, construct validity, and minimum levels of detectable and clinically important change for the Neck Disability Index (NDI) and Patient Specific Functional Scale (PSFS) in cohort of patients with cervical radiculopathy. SUMMARY OF BACKGROUND DATA: To date, no studies have investigated the psychometric properties of the NDI or PSFS in a cohort of patients with cervical radiculopathy. METHODS: Thirty-eight patients with cervical radiculopathy undergoing physical therapy completed the NDI and PSFS, and Numerical Pain Rating Scale (NPRS) at the baseline examination and at a follow-up. In addition, at follow-up, patients completed a 15-point global rating of change (GROC), which was used to dichotomize patients as improved or stable. Changes in the NDI and PSFS were then used to assess test-retest reliability, construct validity, and minimal levels of detectable and clinically important change. RESULTS: Test-retest reliability was moderate for the NDI (intraclass correlation coefficient [ICC] = 0.68; 95% confidence interval [CI], 0.30-0.90) and high for the PSFS (ICC = 0.82; 95% CI, 0.54-0.93). The PSFS was more responsive to change than the NDI. The minimal detectable change for the NDI was 10.2 and for the PSFS 2.1. The minimally clinically important change for the NDI was 7.0 and PSFS 2.0. CONCLUSIONS: Our results suggest that the PSFS exhibits superior reliability, construct validity, and responsiveness in this cohort of patients with cervical radiculopathy compared with the NDI. Further research is needed to examine the ability of these measures to accurately reflect changes in individuals, as well as large samples of patients.

Interrater reliability of the history and physical examination in patients with mechanical neck pain.

OBJECTIVE: To examine the interrater reliability of the history and physical examination in patients with mechanical neck pain. DESIGN: Single-group repeated measures for interrater reliability. SETTING: Outpatient physical therapy clinic. PARTICIPANTS: Twenty-two patients with mechanical neck pain underwent a standardized history and physical examination by a physical therapist. INTERVENTION: Following a 5-minute break, a second therapist who was blind to the findings of examiner 1 performed the second standardized history and physical examination. MAIN OUTCOME MEASURES: The Cohen kappa and weighted kappa were used to calculate the interrater reliability of ordinal level data from the history and physical examination. Intraclass correlation coefficients model 2,1 (ICC(2,1)) and the 95% confidence intervals were calculated to determine the interrater reliability for continuous variables. RESULTS: The kappa coefficients ranged from -.06 to .90 for the variables obtained from the history. Reliability values for categorical data collected during the physical examination ranged from no to substantial agreement depending on the particular test and measure. ICC(2,1) for cervical range of motion (ROM) measurements ranged between .66 and .78. CONCLUSIONS: We have reported the interrater reliability of the history and physical examination in a group of patients with a primary report of neck pain. The reliability variables varied considerably for manual assessment techniques and were significantly higher for the examination of muscle length and cervical ROM. Ultimately, it will be up to each clinician to determine if a particular test or measure poses adequate reliability to assist in the clinical decision making process.

Manual physical therapy interventions and exercise for patients with temporomandibular disorders.

The purpose of this study was to investigate the outcome of a series of consecutive patients with temporomandibular disorder (TMD) who were treated with manual physical therapy interventions and exercise. Consecutive patients with the clinical presentation of TMD completed several self-report measures and underwent a standardized historical and physical examination. Following the examination, patients received a multimodal treatment approach incorporating manual physical therapy and exercise. All self-report questionnaires were completed at a 2-week follow-up. Paired t-tests were performed between the baseline and 2-week follow-up scores. The mean TMD Disability Index scores were 32.1% (15.4%) at baseline and 18.3% (12.5%) at the 2-week follow-up, representing an improvement of 13.9% (CI: 8.2%, 19.5%) (p < 0.05). Patient Specific Functional Scale (PSFS) scores improved 3.1 points (CI: 2.3, 3.9) (p < 0.05). These results suggest that patients with TMD who are treated with a rehabilitation program including manual physical therapy interventions plus exercise, with or without iontophoresis with dexamethasone, can demonstrate clinically meaningful improvements in disability and overall perceived change in a relatively short period of time.

Clinical outcomes following manual physical therapy and exercise for hip osteoarthritis: A case series.

STUDY DESIGN: Case series describing the outcomes of individual patients with hip osteoarthritis treated with manual physical therapy and exercise. CASE DESCRIPTION: Seven patients referred to physical therapy with hip osteoarthritis and/or hip pain were included in this case series. All patients were treated with manual physical therapy followed by exercises to maximize strength and range of motion. Six of 7 patients completed a Harris Hip Score at initial examination and discharge from physical therapy, and 1 patient completed a Global Rating of Change Scale at discharge. OUTCOMES: Three males and 4 females with a median age of 62 years (range, 52-80 years) and median duration of symptoms of 9 months (range, 2-60 months) participated in this case series. The median number of physical therapy sessions attended was 5 (range, 4-12). The median increase in total passive range of motion of the hip was 82 degrees (range, 70 degrees-86 degrees). The median improvement on the Harris Hip Score was 25 points (range, 15-38 points). The single patient who completed the Global Rating of Change Scale at discharge reported being "a great deal better." Numeric pain rating scores decreased by a mean of 5 points (range, 2-7 points) on 0-to-10-point scale. DISCUSSION: All patients exhibited reductions in pain and increases in passive range of motion, as well as a clinically meaningful improvement in function. Although we can not infer a cause and effect relationship from a case series, the outcomes with these patients are similar to others reported in the literature that have demonstrated superior clinical outcomes associated with manual physical therapy and exercise for hip osteoarthritis compared to exercise alone.

The use of a lumbar spine manipulation technique by physical therapists in patients who satisfy a clinical prediction rule: a case series.

STUDY DESIGN: A case series of patients with low back pain (LBP) who satisfy a clinical prediction rule (CPR). BACKGROUND: A CPR that identifies patients with LBP who are likely to respond with rapid and prolonged reductions in pain and disability following spinal manipulation was developed and recently validated. The CPR developed to predict favorable response to manipulation investigated the effects of only 1 manipulation technique. The accuracy of the CPR for predicting outcomes using other manipulation techniques is not known. The purpose of the case series was to describe the outcomes of patients presenting to physical therapy with LBP who met the CPR and were treated with an alternative lumbar manipulation technique. CASE DESCRIPTION: Consecutive patients referred to physical therapy who satisfied the eligibility criteria, including the presence of at least 4 of the 5 criteria on the CPR, were invited to participate in the case series. Patients were treated for 2 visits with a side-lying lumbar manipulation technique, followed by a basic range of motion exercise. Patients who exhibited a 50% reduction or greater in disability, as measured by the Oswestry Disability Index (ODI), were considered to have experienced a successful outcome. OUTCOMES: A total of 12 patients participated in the case series. The mean age of the group was 39 years (SD, 8.9 years) and the median duration of symptoms was 19 days (range, 8-148 days). Of the 12 patients who participated in this case series, the mean reduction in disability as measured with the ODI was 57% (SD, 9%). Only 1 patient did not surpass the 50% reduction in ODI scores. DISCUSSION: Eleven of the 12 patients (92%) in this case series who satisfied the CPR and were treated with an alternative lumbar manipulation technique demonstrated a successful outcome in 2 visits. It is plausible that patients with LBP who satisfy the CPR may obtain a successful outcome with either manipulation technique directed at the lumbopelvic region.

A description of physical therapists' knowledge in managing musculoskeletal conditions.

BACKGROUND: Physical therapists increasingly provide direct access services to patients with musculoskeletal conditions, and growing evidence supports the cost-effectiveness of this mode of healthcare delivery. However, further evidence is needed to determine if physical therapists have the requisite knowledge necessary to manage musculoskeletal conditions. Therefore, the purpose of this study was to describe physical therapists' knowledge in managing musculoskeletal conditions. METHODS: This study utilized a cross-sectional design in which 174 physical therapist students from randomly selected educational programs and 182 experienced physical therapists completed a standardized examination assessing knowledge in managing musculoskeletal conditions. This same examination has been previously been used to assess knowledge in musculoskeletal medicine among medical students, physician interns and residents, and across a variety of physician specialties. RESULTS: Experienced physical therapists had higher levels of knowledge in managing musculoskeletal conditions than medical students, physician interns and residents, and all physician specialists except for orthopaedists. Physical therapist students enrolled in doctoral degree educational programs achieved significantly higher scores than their peers enrolled in master's degree programs. Furthermore, experienced physical therapists who were board-certified in orthopaedic or sports physical therapy achieved significantly higher scores and passing rates than their non board-certified colleagues. CONCLUSION: The results of this study may have implications for health and public policy decisions regarding the suitability of utilizing physical therapists to provide direct access care for patients with musculoskeletal conditions.

Lumbar spine segmental mobility assessment: an examination of validity for determining intervention strategies in patients with low back pain.

OBJECTIVE: To examine the predictive validity of posterior-anterior (PA) mobility testing in a group of patients with low back pain (LBP). DESIGN: Randomized controlled trial. SETTING: Outpatient physical therapy clinics. PARTICIPANTS: Patients with LBP (N=131; mean age +/- standard deviation, 33.9+/-10.9 y; range, 19-59 y), and a median symptom duration of 27 days (range, 1-5941 d). Patients completed a baseline examination, including PA mobility testing, and were categorized with respect to both hypomobility and hypermobility (present or absent), and treated for 4 weeks. INTERVENTION: Seventy patients were randomized to an intervention involving manipulation and 61 to a stabilization exercise intervention. MAIN OUTCOME MEASURES: Oswestry Disability Questionnaire (ODQ) scores were collected at baseline and after 4 weeks. Three-way repeated measures analyses of variance (ANOVAs) were performed to assess the effect of mobility categorization and intervention group on the change on the ODQ with time. Number-needed-to-treat (NNT) statistics were calculated. RESULTS: Ninety-three (71.0%) patients were judged to have hypomobility present and 15 (11.5%) were judged with hypermobility present. The ANOVAs resulted in significant interaction effects. Pairwise comparisons showed greater improvements among patients receiving manipulation categorized with hypomobility present versus absent (mean difference, 23.7%; 95% confidence interval [CI], 5.1%-42.4%), and among patients receiving stabilization categorized with hypermobility present versus absent (mean difference, 36.4%; 95% CI, 10.3%-69.3%). For patients with hypomobility, failure rates were 26% with manipulation and 74.4% with stabilization (NNT=2.1; 95% CI, 1.6-3.5). For patients with hypermobility, failure rates were 83.3% and 22.2% for manipulation and stabilization, respectively (NNT=1.6; 95% CI, 1.2-10.2). CONCLUSIONS: Patients with LBP judged to have lumbar hypomobility experienced greater benefit from an intervention including manipulation; those judged to have hypermobility were more likely to benefit from a stabilization exercise program.

Manual physical therapy, cervical traction, and strengthening exercises in patients with cervical radiculopathy: a case series.

STUDY DESIGN: A case series of consecutive patients with cervical radiculopathy. BACKGROUND: A multitude of physical therapy interventions have been proposed to be effective in the management of cervical radiculopathy. However, outcome studies using consistent treatment approaches on a well-defined sample of patients are lacking. The purpose of this case series is to describe the outcomes of a consecutive series of patients presenting to physical therapy with cervical radiculopathy and managed with the use of manual physical therapy, cervical traction, and strengthening exercises. CASE DESCRIPTION: Eleven consecutive patients (mean age, 51.7 years; SD, 8.2) who presented with cervical radiculopathy on the initial examination were treated with a standardized approach, including manual physical therapy, cervical traction, and strengthening exercises of the deep neck flexors and scapulothoracic muscles. At the initial evaluation all patients completed self-report measures of pain and function, including a numeric pain rating scale (NPRS), the Neck Disability Index (NDI), and the Patient-Specific Functional Scale (PSFS). All patients again completed the outcome measures, in addition to the global rating of change (GROC), at the time of discharge from therapy and at a 6-month follow-up session OUTCOMES: Ten of the 11 patients (91%) demonstrated a clinically meaningful improvement in pain and function following a mean of 7.1 (SD, 1.5) physical therapy visits and at the 6-month follow-up. DISCUSSION: Ninety-one percent (10 of 11) of patients with cervical radiculopathy in this case series improved, as defined by the patients classifying their level of improvement as at least "quite a bit better" on the GROC. However, because a cause-and-effect relationship cannot be inferred from a case series, follow-up randomized clinical trials should be performed to further investigate the effectiveness of manual physical therapy, cervical traction, and strengthening exercises in a homogeneous group of patients with cervical radiculopathy.

Screening for vertebrobasilar insufficiency in patients with neck pain: manual therapy decision-making in the presence of uncertainty.

Growing evidence supports the effectiveness of manual therapy interventions in patients with neck pain; however, considerable attention has also been afforded to the potential risks such as vertebrobasilar insufficiency (VBI). Despite the existence of guidelines advocating specific screening procedures, research does not support the ability to accurately identify patients at risk. The logical question becomes, "How does one proceed in the absence of certainty?" Given the lack of clear direction for decision making in the peer-reviewed literature, this commentary discusses the uncertainties that exist regarding the ability to identify patients at risk for VBI. The authors hope that this commentary adds additional perspective on manual therapy decision-making strategies in the presence of uncertainty.

Reliability of a measurement of neck flexor muscle endurance.

BACKGROUND AND PURPOSE: Neck flexor muscle endurance has been negatively correlated with cervical pain and dysfunction. The purposes of this study were to determine rater reliability in subjects both with and without neck pain and to determine whether there was a difference in neck flexor muscle endurance between the 2 groups. SUBJECTS: Forty-one subjects with and without neck pain were enrolled in this repeated-measures reliability study. METHODS: Two raters used an isometric neck retraction test to assess neck flexor muscle endurance for all subjects during an initial session, and subjects without neck pain returned for testing 1 week later. RESULTS: For the group without neck pain, intrarater reliability was good to excellent (intraclass correlation coefficient [ICC(3,1)]=.82-.91), and interrater reliability was moderate to good (ICC[2,1]=.67-.78). The associated standard error of measurement (SEM) ranged from 8.0 to 11.0 seconds and from 12.6 to 15.3 seconds, respectively. For the group with neck pain, interrater reliability was moderate (ICC[2,1]=.67, SEM=11.5). Neck flexor muscle endurance test results for the group without neck pain (mean=38.95 seconds, SD=26.4) and the group with neck pain (mean=24.1 seconds, SD=12.8) were significantly different. DISCUSSION AND CONCLUSION: Reliability coefficients differed between the 2 groups and ranged from moderate to excellent and improved after the first test session. The interrater reliability of data obtained with the neck flexor muscle endurance test in people with neck pain must be improved in order for clinicians to distinguish a clinically meaningful change from measurement error. Neck flexor muscle endurance was both statistically and clinically greater for subjects without neck pain than for those with neck pain.

The influence of experience and specialty certifications on clinical outcomes for patients with low back pain treated within a standardized physical therapy management program.

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, 4.01, 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.

Clinical hip tests and a functional squat test in patients with knee osteoarthritis: reliability, prevalence of positive test findings, and short-term response to hip mobilization.

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.

Proposal of a classification system for patients with neck pain.

It is likely that patients with neck pain are not a homogeneous group, but, instead, consist of a variety of subgroups, each of which may benefit from a specific intervention matched to the patient's signs and symptoms. Studies to date have largely failed to account for this possibility, which may compromise the statistical power of research and ultimately fail to provide guidance for clinical decision making. Classification provides a means of breaking down a larger entity into more homogeneous subgroups of patients, based on examination data. Classification can guide the determination of a patient's prognosis, and the selection of the most appropriate intervention strategy. Classification has received considerable attention in the management of patients with low back pain, and evidence is emerging regarding its benefits. There has been considerably less effort made towards examining classification as it pertains to patients with neck pain. The purpose of this clinical commentary is to examine the current literature and to propose a classification system for patients with neck pain, based on the overall goal of treatment. The approach is based on published evidence when possible and is also informed by clinical experience and expert opinion. Classification decisions are based on the integration of data from a variety of information from the history and physical examination. The end result of the classification process is to determine the treatment approach believed to be most likely to maximize the clinical outcome for an individual patient with neck pain.
