Objective The Patient-Specific Functional Scale (PSFS) is a patient-reported outcome measure used to assess functional limitations. Recently, the PSFS 2.0 was proposed; this instrument includes an inverse numeric rating scale and an additional list of activities that patients can choose. The aim of this study was to assess the test–retest reliability, measurement error, responsiveness, and minimal important change of the PSFS 2.0 when used by patients with nonspecific neck pain. Methods Patients with nonspecific neck pain completed a numeric rating scale, the PSFS 2.0, and the Neck Disability Index at baseline and again after 12 weeks. The Global Perceived Effect (GPE) was also collected at 12 weeks and used as an anchor. Test–retest measurement was assessed by completion of a second PSFS 2.0 after 1 week. Measurement error was calculated using a Bland–Altman plot. The receiver operating characteristic method with the anchor (GPE) functions as the reference standard was used for calculating the minimal important change. Results One hundred patients were included, with 5 lost at follow-up. No floor and ceiling effects were reported. In the test–retest analysis, the mean difference was 0.15 (4.70 at first test and 4.50 at second test). The ICC (mixed models) was 0.95, indicating high agreement (95% CI = 0.92–0.97). For measurement error, the upper and lower limits of agreement were 0.95 and −1.25 points, respectively, with a smallest detectable change of 1.10. The minimal important change was determined to be 2.67 points. The PSFS 2.0 showed satisfactory responsiveness, with an area under the curve of 0.82 (95% CI = 0.70–0.93). There were substantial to high correlations between the change scores of the PSFS 2.0 and the Neck Disability Index and GPE (0.60 and 0.52, respectively; P  < .001). Conclusion The PSFS 2.0 is a reliable and responsive patient-reported outcome measure for use by patients with neck pain. [ABSTRACT FROM AUTHOR]

Background. Little is known about the effectiveness of exercise programs after decompression surgery for subacromial impingement syndrome. For patients with difficulty returning to usual activities, special efforts may be needed to improve shoulder function. Objective. The purpose of this study was to evaluate the effectiveness at 3 and 12 months of a standardized physical therapy exercise intervention compared with usual care in patients with difficulty returning to usual activities after subacromial decompression surgery. Design. A multicenter randomized controlled trial was conducted. Setting. The study was conducted in 6 public departments of orthopedic surgery, 2 departments of occupational medicine, and 2 physical therapy training centers in Central Denmark Region. Patients. One hundred twenty-six patients reporting difficulty returning to usual activities at the postoperative clinical follow-up 8 to 12 weeks after subacromial decompression surgery participated. Intervention. A standardized exercise program consisting of physical therapist-supervised individual training sessions and home training was used. Outcome Measures. The primary outcome measure was the Oxford Shoulder Score. Secondary outcome measures were the Constant Score and the Fear-Avoidance Beliefs Questionnaire. Results. At 3 and 12 months, follow-up data were obtained for 92% and 83% of the patients, respectively. Intention-to-treat analyses suggested a between-group difference on the Oxford Shoulder Score favoring the exercise group at 3 months, with an adjusted mean difference of 2.0 (95% confidence interval = -0.5, 4.6), and at 12 months, with an adjusted mean difference of 5.8 (95% confidence interval=2.8, 8.9). Significantly larger improvements for the exercise group were observed for most secondary and supplementary outcome measures. Limitations. The nature of the exercise intervention did not allow blinding of patients and care providers. Conclusion. The standardized physical therapy exercise intervention resulted in statistically significant and clinically relevant improvement in shoulder pain and function at 12 months compared with usual care.

STUDY DESIGN: A prospective cohort study nested in a randomized controlled trial. OBJECTIVES: To determine and compare responsiveness and minimal clinically important change of the modified Constant score (CS) and the Oxford Shoulder Score (OSS). BACKGROUND: The OSS and the CS are commonly used to assess shoulder outcomes. However, few studies have evaluated the measurement properties of the OSS and CS in terms of responsiveness and minimal clinically important change. METHODS: The study included 126 patients who reported having difficulty returning to usual activities 8 to 12 weeks after arthroscopic decompression surgery for subacromial impingement syndrome. The assessment at baseline and at 3 months included the OSS, the CS, and the European Quality of Life-5 Dimensions-3 Level (EQ- 5D-3L) index. Responsiveness was assessed as follows: by correlation analysis between the change scores of the OSS, CS, and EQ-5D-3L index, and the Patient Global Impression of Change (PGIC) scale; by receiver-operating-characteristic (ROC) curve analysis using the PGIC scale as an external anchor; and by effect-size statistics. RESULTS: At 3 months, a follow-up assessment of 112 patients (89%) was conducted. The change scores of the CS and the OSS were more strongly correlated with the external anchor (PGIC scale) than the change score of the EQ-5D-3L index. The areas under the ROC curves exceeded 0.80 for both shoulder scores, with no significant differences between them, and comparable effect-size estimates were observed for the CS and the OSS. Minimal clinically important change ROC values were 6 points for the OSS and 11 points for the CS, with upper 95% cutoff limits of 12 and 22 points, respectively. CONCLUSION: The CS and the OSS were both suitable for assessing improvement after decompression surgery. [ABSTRACT FROM AUTHOR]

• A single session of dry needling of the obliquus capitis inferior reduces cervical joint position error in people with neck pain. • Dry needling of the obliquus capitis inferior does not have an effect on cervical movement sense or postural stability. • Dry needling of the obliquus capitis inferior increases upper cervical range of motion measured with the flexion rotation test. Impairments of sensorimotor control relating to head and eye movement control and postural stability are often present in people with neck pain. The upper cervical spine and particularly the obliquus capitis inferior (OCI) play an important proprioceptive role; and its impairment may alter cervical sensorimotor control. Dry needling (DN) is a valid technique to target the OCI. To investigate if a single DN session of the OCI muscle improves head and eye movement control-related outcomes, postural stability, and cervical mobility in people with neck pain. Forty people with neck pain were randomly assigned to receive a single session of DN or sham needling of the OCI. Cervical joint position error (JPE), cervical movement sense, standing balance and oculomotor control were examined at baseline, immediately post-intervention, and at one-week follow-up. Active cervical rotation range of motion and the flexion rotation test were used to examine the global and upper cervical rotation mobility, respectively. Linear mixed-models revealed that the DN group showed a decrease of JPE immediately post-intervention compared to the sham group (mean difference [MD]= -0.93°; 95% confidence interval [CI]: -1.85, -0.02) which was maintained at one-week follow-up (MD= -1.64°; 95%CI: -2.85, -0.43). No effects on standing balance or cervical movement sense were observed in both groups. Upper cervical mobility showed an increase immediately after DN compared to the sham group (MD= 5.14°; 95%CI: 0.77, 9.75) which remained stable at one-week follow-up (MD= 6.98°; 95%CI: 1.31, 12.40). Both group showed an immediate increase in global cervical mobility (MD= -0.14°; 95%CI: -5.29, 4.89). The results from the current study suggest that a single session of DN of the OCI reduces JPE deficits and increases upper cervical mobility in patients with neck pain. Future trials should examine if the addition of this technique to sensorimotor control training add further benefits in the management of neck pain. [ABSTRACT FROM AUTHOR]
