An orthopedic manual physical therapy fellowship training's impact on professional development, involvement, personal lives, and income - A survey study.

Introduction: Little research exists investigating the personal and professional outcomes of postprofessional physical therapy (PT) training. Therefore, the purpose of the current descriptive, web-based survey study was to determine self-reported outcomes from a postprofessional PT fellowship program, including graduate professional, educational, and research involvement; perceptions of the impact of training on clinical and professional attributes; changes in employment and income; and barriers to training. Methods: Graduates of a part-time, hybrid-model, multisite orthopedic manual PT fellowship program were invited to complete the web-based survey. Descriptive data analyses were performed for all quantitative data, and responses to questions were analyzed and categorized into themes. Results: Of the 77 fellowship graduates, 75 (97%) completed the survey. Graduates were involved in teaching; 43% (32/75) filled lead instructor roles in PT education programs. Further, 75% (57/75) were involved in research. The mean (SD) and median (range) increase in annual gross income was $9560 ($17,545) and $2,500 ($0-$125,000), respectively. Perceived areas with the largest impact of training included clinical reasoning, patient-centered and evidence-based practice, and professionalism. Life balance and family commitments were frequent barriers during training. Discussion: Graduates noted substantial perceived professional, clinical, and financial benefits to fellowship training. Limitations included lack of a control group and surveying participants from a single program. Future research should determine the influence that program and participant-related factors have on personal and professional lives of graduates and on clinical outcomes. Level of Evidence: Descriptive survey, level 3.

Translational manipulation under anesthesia for patients with frozen shoulder: a case series study with five-year health care utilization and post-manipulative arthroscopic findings.

STUDY DESIGN: Case series study. OBJECTIVES: Although there have been no reported complications from translational manipulation under anesthesia (tMUA) for individuals with adhesive capsulitis (AC) there are no cases reporting surgical findings post tMUA. Also, there are no studies evaluating health care utilization following tMUA. The purpose of this study was to: (1) report clinical outcomes following tMUA, (2) describe relevant health care costs and utilization following tMUA, and (3) summarize findings from two cases receiving joint arthroscopy following tMUA. METHODS: Fourteen Individuals with AC underwent tMUA. Range of motion (ROM) and Shoulder Pain and Disability Index (SPADI) values were collected at baseline and six weeks follow-up. Shoulder-related health care cost and utilization were analyzed for a five-year period following tMUA. Two additional patients with AC underwent tMUA followed by arthroscopic assessment for evidence of iatrogenic injury. RESULTS: Thirteen patients completed the six-week follow-up. Mean change scores for ROM and SPADI values were flexion; +38.5°, abduction; +71.1°, external rotation (shoulder abducted); +49.8°, internal rotation (shoulder abducted); +26.6°, SPADI scores; +44.4. 13 patient records were analyzed for health care utilization. Ten of the 13 patients utilized no additional shoulder-related health care. Surgical evaluation revealed no evidence of iatrogenic injury. DISCUSSION: Clinical outcomes were similar to previous studies. Utilization data indicated that for the majority of patients, little shoulder-related health care was utilized. Surgical evaluation provided further evidence that tMUA performed by a physical therapist is safe. Future research will be required to establish a causal relationship between tMUA and the results observed in this study. LEVEL OF EVIDENCE: Therapy, Level 4.

The impact of physical therapy residency or fellowship education on clinical outcomes for patients with musculoskeletal conditions.

STUDY DESIGN: A retrospective cohort design was conducted using data from an electronic survey and an existing commercial outcomes database. OBJECTIVE: To compare the clinical outcomes of patients with musculoskeletal conditions treated by physical therapists who had completed residency or fellowship programs versus those who had not. BACKGROUND: There is an increasing focus on specialization through postprofessional education in physical therapy residency and fellowship programs. Scant evidence exists that evaluates the influence of postprofessional clinical education on actual patient outcomes. METHODS: Physical therapists using a national outcomes database were surveyed to determine their level of postprofessional education. Survey responders were categorized into 1 of 3 groups that included no residency or fellowship training, residency trained, or fellowship trained. Outcomes for 25 843 patients with musculoskeletal conditions treated by 363 therapists from June 2012 to June 2013 were extracted from the database. These data were analyzed to identify any differences in functional status change and efficiency achieved between the 3 groups. Potentially confounding variables were controlled for statistically. RESULTS: The fellowship-trained group of physical therapists achieved functional status changes and efficiency that were greater than those of the other groups. No difference in functional status change was observed between the residency group and the therapists without residency or fellowship training. The group without residency or fellowship training was more efficient than the residency-trained group. Fellowship-trained therapists were more likely to achieve greater treatment effect sizes than therapists without residency or fellowship training. Residency-trained therapists were less likely to achieve greater treatment effect sizes than the therapists without residency or fellowship training. CONCLUSION: These data demonstrate that fellowship training may contribute to statistically greater patient outcomes. Residency training did not appear to contribute to improved patient functional status change or efficiency. It is unknown whether the statistical differences observed would be clinically meaningful for patients.

Associations between physical therapy and long-term outcomes for individuals with lumbar spinal stenosis in the SPORT study.

BACKGROUND CONTEXT: A period of nonsurgical management is advocated before surgical treatment for most patients with lumbar spinal stenosis. Currently, little evidence is available to define optimal nonsurgical management. Physical therapy is often used, however its use and effectiveness relative to other nonsurgical strategies has not been adequately explored. PURPOSE: Describe the use of physical therapy and other nonsurgical interventions by patients with lumbar spinal stenosis and examine the relationship between physical therapy and long-term prognosis. STUDY DESIGN: Secondary analysis of the Spine Patient Outcomes Research Trial (SPORT) combining data from randomized and observational studies. SETTING: Thirteen spine clinics in 11 states in the United States. PATIENT SAMPLE: Patients with lumbar spinal stenosis receiving nonsurgical management including those who did or did not receive physical therapy within 6 weeks of enrollment. OUTCOME MEASURES: Primary outcome measures included crossover to surgery, the bodily pain and physical function scales changes from the Survey Short Form 36 (SF-36), and the modified Oswestry Disability Index. Secondary outcome measures were patient satisfaction and the Sciatica Bothersomeness Index. METHODS: Baseline characteristics and rates of crossover to surgery were compared between patients who did or did not receive physical therapy. Baseline factors predictive of receiving physical therapy were examined with logistic regression. Mixed effects models were used to compare outcomes between groups at 3 and 6 months and 1 year after enrollment adjusted for baseline severity and patient characteristics. RESULTS: Physical therapy was used in the first 6 weeks by 90 of 244 patients (37%) and was predicted by the absence of radiating pain and being single instead of married. Physical therapy was associated with a reduced likelihood of crossover to surgery after 1 year (21% vs. 33%, p=.045), and greater reductions on the Short Form 36 physical functioning scale after 6 months (mean difference=6.0, 95% confidence interval: 0.2-11.7) and 1 year (mean difference=6.5, 95% confidence interval: 0.6-12.4). There were no differences in bodily pain or Oswestry scores across time. CONCLUSIONS: Many patients with lumbar spinal stenosis pursuing conservative management receive physical therapy. Using physical therapy was associated with reduced likelihood of patients receiving surgery within 1 year. Results for other outcomes were mixed with no differences in several measures. Further research is needed to examine the effectiveness of physical therapy relative to other nonsurgical management strategies for patients with lumbar spinal stenosis.

Manual physical therapy and exercise versus supervised home exercise in the management of patients with inversion ankle sprain: a multicenter randomized clinical trial.

STUDY DESIGN: Randomized clinical trial. OBJECTIVE: To compare the effectiveness of manual therapy and exercise (MTEX) to a home exercise program (HEP) in the management of individuals with an inversion ankle sprain. BACKGROUND: An in-clinic exercise program has been found to yield similar outcomes as an HEP for individuals with an inversion ankle sprain. However, no studies have compared an MTEX approach to an HEP. METHODS: Patients with an inversion ankle sprain completed the Foot and Ankle Ability Measure (FAAM) activities of daily living subscale, the FAAM sports subscale, the Lower Extremity Functional Scale, and the numeric pain rating scale. Patients were randomly assigned to either an MTEX or an HEP treatment group. Outcomes were collected at baseline, 4 weeks, and 6 months. The primary aim (effects of treatment on pain and disability) was examined with a mixed-model analysis of variance. The hypothesis of interest was the 2-way interaction (group by time). RESULTS: Seventy-four patients (mean ± SD age, 35.1 ± 11.0 years; 48.6% female) were randomized into the MTEX group (n = 37) or the HEP group (n = 37). The overall group-by-time interaction for the mixed-model analysis of variance was statistically significant for the FAAM activities of daily living subscale (P<.001), FAAM sports subscale (P<.001), Lower Extremity Functional Scale (P<.001), and pain (P ≤.001). Improvements in all functional outcome measures and pain were significantly greater at both the 4-week and 6-month follow-up periods in favor of the MTEX group. CONCLUSION: The results suggest that an MTEX approach is superior to an HEP in the treatment of inversion ankle sprains. Registered at clinicaltrials.gov (NCT00797368). LEVEL OF EVIDENCE: Therapy, level 1b-.

Psychometric properties of selected tests in patients with lumbar spinal stenosis.

BACKGROUND CONTEXT: The psychometric properties of many outcome tools commonly used with patients with lumbar spinal stenosis have yet to be examined. PURPOSE: Examine the test-retest reliability, responsiveness, and minimum levels of detectable and clinically important differences for several outcome measures in a cohort of patients with lumbar spinal stenosis. STUDY DESIGN/SETTING: Cohort secondary analysis of a randomized clinical trial of patients with lumbar spinal stenosis receiving outpatient physical therapy. PATIENT SAMPLE: Fifty-five patients (mean age, 69.5 years; standard deviation, ±7.9 years; 43.1% females) presenting with lumbar spinal stenosis to physical therapy. OUTCOME MEASURES: The Modified Oswestry Disability Index, Modified Swiss Spinal Stenosis Scale (SSS), Patient Specific Functional Scale, and Numeric Pain Rating Scale (NPRS). METHODS: All patients completed the Oswestry Disability Index, SSS, Patient Specific Functional Scale, and NPRS at the baseline examination and at a follow-up. In addition, patients completed a 15-point Global Rating of Change at follow-up, which was used to categorize whether patients experienced clinically meaningful change. Changes in the Oswestry Disability Index, SSS, Patient Specific Functional Scale, and NPRS were then used to assess test-retest reliability, responsiveness, and minimum levels of detectable and clinically important differences. RESULTS: The Oswestry Disability Index was the only outcome measure to exhibit excellent test-retest reliability with an intraclass correlation coefficient of 0.86 (95% confidence interval, 0.63-0.93). All others ranged between fair and moderate. The Oswestry Disability Index, SSS, and Patient Specific Functional Scale exhibited varying levels of responsiveness, each of which was superior to the NPRS. The minimal clinically important difference for the Oswestry Disability Index was five points, the SSS was 0.36 and 0.10 for symptoms subscale and functional subscale, respectively, 1.3 for the Patient Specific Functional Scale, and for the NPRS, 1.25 for back/buttock symptoms and 1.5 for thigh/leg symptoms. CONCLUSIONS: The results of our study indicate that the Oswestry Disability Index, SSS, and Patient Specific Functional Scale possess adequate psychometric properties to be used in the outcome assessment of patients with lumbar spinal stenosis. However, further investigation is needed to validate these findings in other samples of patients with lumbar spinal stenosis and nonspecific low back pain.

Low back pain.

The Orthopaedic Section of the American Physical Therapy Association (APTA) has an ongoing effort to create evidence-based practice guidelines for orthopaedic physical therapy management of patients with musculoskeletal impairments described in the World Health Organization's International Classification of Functioning, Disability, and Health (ICF). The purpose of these low back pain clinical practice guidelines, in particular, is to describe the peer-reviewed literature and make recommendations related to (1) treatment matched to low back pain subgroup responder categories, (2) treatments that have evidence to prevent recurrence of low back pain, and (3) treatments that have evidence to influence the progression from acute to chronic low back pain and disability.

Lumbar spinal stenosis-diagnosis and management of the aging spine.

Low back pain and lumbar spinal stenosis (LSS) is an extensive problem in the elderly presenting with pain, disability, fall risk and depression. The incidence of LSS is projected to continue to grow as the population ages. In light of the risks, costs and lack of long-term results associated with surgery, and the positive outcomes in studies utilizing physical therapy interventions for the LSS patient, a non-invasive approach is recommended as a first line of intervention. This Masterclass presents an overview of LSS in terms of clinical examination, diagnosis, and intervention. A focused management approach to the patient with LSS is put forward that emphasizes a defined four-fold approach of patient education, manual physical therapy, mobility and strengthening exercises, and aerobic conditioning.

Psychometric properties of the Fear-Avoidance Beliefs Questionnaire and Tampa Scale of Kinesiophobia in patients with shoulder pain.

OBJECTIVE: To investigate the reliability and validity of 2 commonly used measures of pain related fear in patients with shoulder pain. DESIGN: A preplanned secondary analysis of a prospective single-arm trial involving a repeated-measures design. SETTING: Outpatient physical therapy clinics. PARTICIPANTS: Patients (N=80) with a primary report of shoulder pain. INTERVENTION: All patients completed the outcome measures at baseline and at follow-up. MAIN OUTCOME MEASURES: Patients completed a modified Fear-Avoidance Beliefs Questionnaire (FABQ), the 11-item version of Tampa Scale of Kinesiophobia (TSK-11), and the Shoulder Pain and Disability Index (SPADI) at baseline and at a 48-hour follow-up. Patients were dichotomized as improved or stable at follow-up based on the Global Rating of Change. RESULTS: Factor analysis indicated 3 stable factors for the FABQ and 1 stable factor for the TSK-11. Shoulder specific scoring for the FABQ and TSK-11 were used in subsequent analyses. Test-retest reliability intraclass correlation coefficient (ICC) was substantial for the FABQ and the TSK-11. The FABQ correlated significantly with SPADI pain and disability scores, while the TSK-11 correlated significantly only with SPADI pain scores. The shoulder-specific FABQ-W (work beliefs subscale) was a better than chance predictor of missing days of work during the 48-hour study period. CONCLUSIONS: The modified FABQ and TSK-11 may be appropriate for use in patients with shoulder pain. Shoulder-specific scoring of these measures resulted in substantial test-retest reliability, and the FABQ correlated with the SPADI for pain and disability. The FABQ also showed potential for prediction of short-term work loss in this sample. Pain-related fear may be an important variable in patients with shoulder pain and merits future consideration in longitudinal studies.

Some factors predict successful short-term outcomes in individuals with shoulder pain receiving cervicothoracic manipulation: a single-arm trial.

BACKGROUND: It has been reported that manipulative therapy directed at the cervical and thoracic spine may improve outcomes in patients with shoulder pain. To date, limited data are available to help physical therapists determine which patients with shoulder pain may experience changes in pain and disability following the application of these interventions. OBJECTIVE: The purpose of this study was to identify prognostic factors from the history and physical examination in individuals with shoulder pain who are likely to experience rapid improvement in pain and disability following cervical and thoracic spine manipulation. DESIGN: This was a prospective single-arm trial. SETTING: This study was conducted in outpatient physical therapy clinics. PARTICIPANTS: The participants were individuals who were seen by physical therapists for a primary complaint of shoulder pain. INTERVENTION AND MEASUREMENTS: Participants underwent a standardized examination and then a series of thrust and nonthrust manipulations directed toward the cervicothoracic spine. Individuals were classified as having achieved a successful outcome at the second and third sessions based on their perceived recovery. Potential prognostic 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 80 individuals were included in the data analysis, of which 49 had a successful outcome. Five prognostic variables were retained in the final regression model. If 3 of the 5 variables were present, the chance of achieving a successful outcome improved from 61% to 89% (positive likelihood ratio=5.3). LIMITATIONS: A prospective single-arm trial lacking a control group does not allow for inferences to be made regarding cause and effect. The statistical procedures used may result in "overfitting" of the model, which can result in low precision of the prediction accuracy, and the bivariate analysis may have resulted in the rejection of some important variables. CONCLUSIONS: The identified prognostic variables will allow clinicians to make an a priori identification of individuals with shoulder pain who are likely to experience short-term improvement with cervical and thoracic spine manipulation. Future studies are necessary to validate these findings.

Responsiveness of the Neck Disability Index in patients with mechanical neck disorders.

PURPOSE: Report the test-retest reliability, construct validity, minimum clinically important difference (MCID), and minimal detectable change (MDC) for the Neck Disability Index (NDI). STUDY DESIGN/SETTING: Cohort study of patients presenting to outpatient physical therapy clinics. PATIENT SAMPLE: Ninety-one subjects with a primary complaint of neck pain, with or without concomitant upper extremity (UE) symptoms, who were participants in a randomized clinical trial. OUTCOME MEASURES: NDI and the 15-point Global Rating of Change (GRC) self-report measures. METHODS: All subjects completed the NDI at baseline and at a 3-week follow-up. Additionally, subjects completed the GRC scale, which was used to dichotomize patients into improved or stable groups. Changes in the NDI were used to assess test-retest reliability, construct validity, MCID, and MDC. RESULTS: Test-retest reliability was moderate for the NDI (intraclass correlation coefficient, 0.64; 95% confidence interval, 0.19-0.84). For the NDI, the MCID was 7.5 points and the MDC was 10.2 points. CONCLUSIONS: The NDI appears to demonstrate adequate responsiveness based on statistical reference criteria when used in a sample that approximates the high percentage of patients with neck pain and concomitant UE referred symptoms. Because the MCID is within the bounds of measurement error, a 10-point change (the MDC) should be used as the MCID.

Predicting short-term response to thrust and nonthrust manipulation and exercise in patients post inversion ankle sprain.

STUDY DESIGN: Prospective-cohort/predictive-validity study. OBJECTIVES: To develop a clinical prediction rule (CPR) to identify patients who had sustained an inversion ankle sprain who would likely benefit from manual therapy and exercise. BACKGROUND: No studies have investigated the predictive value of items from the clinical examination to identify patients with ankle sprains likely to benefit from manual therapy and general mobility exercises. METHODS AND MEASURES: Consecutive patients with a status of post inversion ankle sprain underwent a standardized examination followed by manual therapy (both thrust and nonthrust manipulation) and general mobility exercises. Patients 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: Eighty-five patients were included in the data analysis, of which 64 had a successful outcome (75%). A CPR with 4 variables was identified. If 3 of the 4 variables were present the accuracy of the rule was maximized (positive likelihood ratio, 5.9; 95% CI: 1.1, 41.6) and the posttest probability of success increased to 95%. CONCLUSIONS: The CPR provides the ability to a priori identify patients with an inversion ankle sprain who are likely to exhibit rapid and dramatic short-term success with a treatment approach, including manual therapy and general mobility exercises. LEVEL OF EVIDENCE: Prognosis, level 2b.

Manual physical assessment of spinal segmental motion: intent and validity.

Validity of a clinical test can be defined as the extent to which the test actually assesses what it is intended to assess. In order to investigate the validity of manual physical assessment of the spine, it is therefore essential to establish what physical therapists intend to assess when they are applying these tests. The aims of this study were to (1) establish what manual physical therapists are intending to assess while applying passive intervertebral motion tests; and (2) examine the face validity and content validity for manual physical assessment of the spine. We surveyed 1502 members of the national manual physical therapist organisations of New Zealand and the United States of America using a web-based survey instrument. Sixty-six percent of 466 respondents believed passive accessory intervertebral motion (PAIVM) tests were valid for assessing quantity of segmental motion, and 76% believed passive physiologic intervertebral motion (PPIVM) tests were valid for assessing quantity of segmental motion. Ninety-eight percent of manual physical therapists base treatment decisions at least in part on the results of segmental motion tests. Quality of resistance to passive segmental motion was considered of greater importance than quantity of kinematic motion during PAIVM tests, while the quality of complex kinematic motion was considered of greater importance than quantity of displacement kinematics during PPIVM tests. Manual physical therapists accept the face validity of manual physical assessment of spinal segmental motion to a great extent, however a minority voice scepticism. Content validity is dominated by concepts of segmental kinematics and the force-displacement relationship. Intent of assessment does, however, vary widely between therapists. These data will inform the design of concurrent validity studies. Further work is recommended to increase consistency of intent, methodology and terminology in manual physical assessment of the spine.

The effectiveness of manual physical therapy and exercise for mechanical neck pain: a randomized clinical trial.

STUDY DESIGN: Randomized clinical trial. OBJECTIVE: To assess the effectiveness of manual physical therapy and exercise (MTE) for mechanical neck pain with or without unilateral upper extremity (UE) symptoms, as compared to a minimal intervention (MIN) approach. SUMMARY OF BACKGROUND DATA: Mounting evidence supports the use of manual therapy and exercise for mechanical neck pain, but no studies have directly assessed its effectiveness for UE symptoms. METHODS: A total of 94 patients referred to 3 physical therapy clinics with a primary complaint of mechanical neck pain, with or without unilateral UE symptoms, were randomized to receive MTE or a MIN approach of advice, motion exercise, and subtherapeutic ultrasound. Primary outcomes were the neck disability index, cervical and UE pain visual analog scales (VAS), and patient-perceived global rating of change assessed at 3-, 6-, and 52-weeks. Secondary measures included treatment success rates and post-treatment healthcare utilization. RESULTS: The MTE group demonstrated significantly larger reductions in short- and long-term neck disability index scores (mean 1-year difference -5.1, 95% confidence intervals (CI) -8.1 to -2.1; P = 0.001) and short-term cervical VAS scores (mean 6-week difference -14.2, 95% CI -22.7 to -5.6; P = 0.001) as compared to the MIN group. The MTE group also demonstrated significant within group reductions in short- and long-term UE VAS scores at all time periods (mean 1-year difference -16.3, 95% CI -23.1 to -9.5; P = 0.000). At 1-year, patient perceived treatment success was reported by 62% (29 of 47) of the MTE group and 32% (15 of 47) of the MIN group (P = 0.004). CONCLUSION: An impairment-based MTE program resulted in clinically and statistically significant short- and long-term improvements in pain, disability, and patient-perceived recovery in patients with mechanical neck pain when compared to a program comprising advice, a mobility exercise, and subtherapeutic ultrasound.

Neck pain: Clinical practice guidelines linked to the International Classification of Functioning, Disability, and Health from the Orthopedic Section of the American Physical Therapy Association.

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.

A primer on selected aspects of evidence-based practice relating to questions of treatment. Part 1: asking questions, finding evidence, and determining validity.

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 first commentary in a 2-part series will review principles relating to steps 1, 2, and 3 of this 5-step model. The purpose of this commentary is to provide a perspective to assist clinicians in formulating foreground questions, searching for the best available evidence, and determining validity of results in studies of interventions for orthopaedic and sports physical therapy.

Psychometric properties of the Neck Disability Index and Numeric Pain Rating Scale in patients with mechanical neck pain.

OBJECTIVE: To examine the psychometric properties including test-retest reliability, construct validity, and minimum levels of detectable and clinically important change for the Neck Disability Index (NDI) and the numeric rating scale (NRS) for pain in a cohort of patients with neck pain. DESIGN: Single-group repeated-measures design. SETTING: Outpatient physical therapy (PT) clinics. PARTICIPANTS: Patients (N=137) presenting to PT with a primary report of neck pain. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: All patients completed the NDI and the NRS at the baseline examination and at a follow-up. At the time of the follow-up, all patients also completed the global rating of change, which was used to dichotomize patients as improved or stable. Baseline and follow-up scores were used to determine the test-retest reliability, construct validity, and minimal levels of detectable and clinically important change for both the NDI and NRS. RESULTS: Test-retest reliability was calculated using an intraclass correlation coefficient (ICC) (NDI ICC=.50; 95% confidence interval [CI], .25-.67; NRS ICC=.76; 95% CI, .51-.87). The area under the curve was .83 (95% CI, .75-.90) for the NDI score and .85 (95% CI, .78-.93) for the NRS score for determining between stable and improved patients. Thresholds for the minimum clinically important difference (MCID) for the NDI were 19-percentage points and 1.3 for the NRS. CONCLUSIONS: Both the NDI and NRS exhibit fair to moderate test-retest reliability in patients with mechanical neck pain. Both instruments also showed adequate responsiveness in this patient population. However, the MCID required to be certain that the change in scores has surpassed a level that could be contributed to measurement error for the NDI was twice that which has previously been reported. Therefore the ongoing analyses of the properties of the NDI in a patient population with neck pain are warranted.
