Interexaminer Agreement and Reliability of an Internationally Endorsed Screening Framework for Cervical Vascular Risks Following Manual Therapy and Exercise:The Go4Safe Project

Objective: Clinicians are recommended to use the clinical reasoning framework developed by the International Federation of Orthopaedic Manipulative Physical Therapists (IFOMPT) to provide guidance regarding assessment of the cervical spine and potential for cervical artery dysfunction prior to manual therapy and exercise. However, the interexaminer agreement and reliability of this framework is unknown. This study aimed to estimate the interexaminer agreement and reliability of the IFOMPT framework among physical therapists in primary care. Methods: Ninety-six patients who consulted a physical therapist for neck pain or headache were included in the study. Each patient was tested independently by 2 physical therapists, from a group of 17 physical therapists (10 pairs) across The Netherlands. Patients and examiners were blinded to the test results. The overall interexaminer agreement, specific agreement per risk category (high-, intermediate-, and low-risk), and interexaminer reliability (weighted κ) were calculated. Results: Overall agreement was 71% (specific agreement in high-risk category = 63%; specific agreement in intermediate-risk category = 38%; specific agreement in low-risk category = 84%). Overall reliability was moderate (weighted κ = 0.39; 95% CI = 0.21-0.57) and varied considerably between pairs of physical therapists (κ = 0.14-1.00). Conclusion: The IFOMPT framework showed an insufficient interexaminer agreement and fair interexaminer reliability among physical therapists when screening the increased risks for vascular complications following manual therapy and exercise prior to treatment. Impact: The IFOMPT framework contributes to the safety of manual therapy and exercise. It is widely adopted in clinical practice and educational programs, but the measurement properties are unknown. This project describes the agreement and reliability of the IFOMPT framework

Risk assessment of vascular complications following manual therapy and exercise for the cervical region: diagnostic accuracy of the International Federation of Orthopaedic Manipulative Physical Therapists framework (The Go4Safe project)

Question: What is the diagnostic accuracy of the International Federation of Orthopaedic Manipulative Physical Therapists (IFOMPT) framework to assess the risk of vascular complications in patients seeking physiotherapy care for neck pain and/or headache? Design: Cross-sectional diagnostic accuracy study. Participants: One hundred and fifty patients seeking physiotherapy for neck pain and/or headache in primary care. Methods: Nineteen physiotherapists performed the index test according to the IFOMPT framework. Patients were classified as having a high, intermediate or low risk of vascular complications, following manual therapy and/or exercise, derived from the estimated risk of the presence of vascular pathology. The reference test was a consensus medical decision reached by a vascular neurologist and an interventional neurologist, with input from a neuroradiologist. The neurologists had access to clinical data and magnetic resonance imaging of the cervical spine, including an angiogram of the cervical arteries. Outcome measures: Diagnostic accuracy measures were calculated for ‘no contraindication’ (ie, the low-risk category) and ‘contraindication’ (ie, the high-risk and intermediate-risk categories) for manual therapy and/or exercise. Sensitivity, specificity, predictive values, likelihood ratios and the area under the curve were calculated. Results: Manual therapy and/or exercise were contraindicated in 54.7% of the patients. The sensitivity of the IFOMPT framework was low (0.50, 95% CI 0.39 to 0.61) and its specificity was moderate (0.63, 95% CI 0.51 to 0.75). The positive and negative likelihood ratios were weak at 1.36 (95% CI 0.93 to 1.99) and 0.79 (95% CI 0.60 to 1.05), respectively. The area under the curve was poor (0.57, 95% CI 0.49 to 0.65). Conclusion: The IFOMPT framework has poor diagnostic accuracy when compared with a reference standard consisting of a consensus medical decision

Probing atmospheric electric fields in thunderstorms through radio emission from cosmic-ray-induced air showers

\u3cp\u3eWe present measurements of radio emission from cosmic ray air showers that took place during thunderstorms. The intensity and polarization patterns of these air showers are radically different from those measured during fair-weather conditions. With the use of a simple two-layer model for the atmospheric electric field, these patterns can be well reproduced by state-of-the-art simulation codes. This in turn provides a novel way to study atmospheric electric fields.\u3c/p\u3
