Manual therapy and cervical artery dysfunction: Identification of potential risk factors in clinical encounters

Applying an osteopathic intervention to improve mild to moderate mental health symptoms: a mixed-methods feasibility study protocol

INTRODUCTION

Mental health services are stretched in the UK and are in need of support. One approach that could improve mental health symptoms is osteopathy. Research suggests that osteopathy influences psychophysiological factors, which could lead to improvements in mental health. The first objective of this protocol is to investigate the feasibility and acceptability of four osteopathic interventions. A secondary aim is to evaluate the interventions' effectiveness for improving psychophysiological and mental health outcomes.

METHODS AND ANALYSIS

This study will be an explanatory mixed-methods design. Participants will be 30 adults who have mild to moderate mental health symptoms and not experiencing any issues with pain. The feasibility and acceptability of the interventions will be the primary outcomes. Secondary outcomes will be physiological measures including heart rate variability, interoceptive accuracy and blood pressure. Psychological outcomes, collected preintervention and postintervention, will also be measured by five standardised questionnaires, which include: (1) the Depression, Anxiety and Stress Scale (DASS); (2) the International Positive and Negative Affect Schedule-Short-Form; (3) Acceptance and Action Questionnaire-II; (4) the Self as Context Scale and (5) and the Multidimensional Assessment of Interoceptive Awareness Version 2. Participants will be randomised to one of four intervention groups and receive a single intervention treatment session. These intervention groups are: (1) high-velocity and articulation techniques, (2) soft-tissue massage, (3) craniosacral techniques, and (4) a combination of these three approaches. Mixed design two (preintervention and postintervention) by the four interventions analysis of covariance models will be used to analyse the quantitative data for each quantitative measure. Participants will also be interviewed about their experiences of the study and interventions and a thematic analysis will be used to analyse this qualitative data. This will aid the assessment of the feasibility and acceptability of the study design.

ETHICS AND DISSEMINATION

The protocol for this feasibility study has received ethical approval from the Department of Psychology Ethics Committee at Swansea University, ethical review reference number: 2022-5603-4810. Feasibility results from this protocol will be published in a peer review journal and presented at both national and international conferences.

DISCUSSION

This study will assess the feasibility and acceptability of conducting osteopathic interventions for improving mental health outcomes. The results from this will help to inform the development of a future randomised controlled trial. The study will also produce original data which could provide preliminary evidence of whether osteopathic approaches are of benefit to individual's mental health in the form of effect sizes, even if they are pain-free.

International Framework for Examination of the Cervical Region for Potential of Vascular Pathologies of the Neck Prior to Musculoskeletal Intervention: International IFOMPT Cervical Framework

SYNOPSIS: This position statement, stemming from the International IFOMPT (International Federation of Orthopaedic Manipulative Physical Therapists) Cervical Framework, was developed based upon the best contemporary evidence and expert opinion to assist clinicians during their clinical reasoning process when considering presentations involving the head and neck. Developed through rigorous consensus methods, the International IFOMPT Cervical Framework guides assessment of the cervical spine region for potential vascular pathologies of the neck in advance of planned interventions. Within the cervical spine, events and presentations of vascular pathologies of the neck are rare but are an important consideration as part of patient examination. Vascular pathologies may be recognizable if the appropriate questions are asked during the patient history-taking process, if interpretation of elicited data enables recognition of this potential, and if the physical examination can be adapted to explore any potential vasculogenic hypothesis.

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.

Should we abandon positional testing for vertebrobasilar insufficiency?

Positional testing for vertebrobasilar insufficiency (VBI) is used by physiotherapists as part of pre-manipulative screening protocols. Recently, the validity of the tests have been questioned because a negative test does not infer safety with cervical manipulative therapy but the reasoning surrounding this opinion may be questioned. While the positional tests were developed to test vertebral artery flow contralateral to the direction of head movement and the subsequent effect on cerebral blood supply, as inferred by symptom reproduction, ultrasound studies have shown that vertebral artery flow is inherently variable. Rather, the tests should be considered as testing for adequacy of collateral flow in particular head positions rather than decreased blood flow in a particular artery, with more attention to characteristics of symptom reproduction. We contend that positional testing for VBI remains valuable for testing adequacy of collateral flow, and also has an important place as part of the differential diagnosis of individuals with dizziness or imbalance. The physiotherapist's ability to differentially diagnose dizziness and recognise the presence or not of VBI is not only critical for prompt medical investigation and management because it is a risk factor for transient ischaemic events and stroke, but has important influences over management decisions regarding cervical musculoskeletal treatment including exercise interventions. Importantly, the positional tests should not be considered as tests of arterial integrity and used to assess the risk of damage to the vertebral or internal carotid artery or presence of cervical arterial dissection. Urgent research is needed before we abandon positional testing prematurely.

Experiences of pregnant women receiving osteopathic care

The state of women's health during pregnancy and in the post-natal period can have profound and long-term effects on their own health and that of their children. Women are increasingly seeking complementary and alternative therapies during pregnancy. The aim of this study was to explore the experiences of women who received osteopathic treatment during pregnancy.

METHOD

This phenomenological study used semi-structured interviews with pregnant patients who were undergoing osteopathic care in northern NSW and south-east Queensland, Australia. Data were analysed thematically.

RESULTS

Osteopathic care provided symptom relief, particularly for low back and pelvic pain. Participants wanted a natural childbirth with minimal medical intervention if possible. Osteopathic care was perceived as helping prepare women's bodies for birth and in so doing helped alleviate anxieties associated with childbirth and with entering the mainstream medical system.

CONCLUSIONS

Pregnant women receiving osteopathic care reported experiencing physical and mental health benefits both during pregnancy and in the post-natal period.
