Brief Summary

Thoracic outlet syndrome (TOS) denotes the collection of symptoms which may arise from compression of the neurovascular structures in the region of the brachial plexus. TOS has historically been a clinical enigma, with lack of consensus regarding its diagnosis limiting the validity of any research into it. Literature and local audit both note significant patient morbidity and redundant use of secondary care clinics and investigations in sufferers. The last decade has seen the creation of a consortium of leaders in the field and development of the CORE-TOS diagnostic tool. This tool has 5 subsets of clinical diagnostic criteria (CDC). Positivity in 4 or more suggests a diagnosis of TOS. The current study seeks to specifically examine whether physiotherapy clinicians - both in primary and secondary care - can consistently identify cases of TOS using the CORE-TOS tool and refer them appropriately to an extended scope physiotherapist (ESP) specialising in the condition. Specific education will be provided to relevant physiotherapists who will be asked to note all relevant CDC in any suspected cases thereafter referred to the ESP in an out-patient physiotherapy department setting. These referrals will follow the standard local pathway to physiotherapy and no clinical testing manoeuvres out with the current scope of physiotherapy will be applied. The patients' case notes will thereafter be retrospectively examined, and the inter-rater reliability of the CDC recorded by the both the referring physiotherapist on their referral and the researcher at initial review. This will analysed using intraclass correlation coefficient, SEM and Bland and Altman's agreement tests, coupled with descriptive analysis.

Outcome Measures

Primary Outcomes (1)

  • CORE-TOS clinical diagnostic criteria

    Number of clinical diagnostic criteria (out of 5) found on clinical examination. This will range from 0 to 5, with a score of 4 or greater required to assume a diagnosis of thoracic outlet syndrome.

    Through study completion, between April 2021 and April 2022

Interventions

Collection of clinical findings from clinical examination, subdivided into 5 sub-categories. Positivity in 4 or 5 of these subcategories is considered diagnostic for thoracic outlet syndrome (TOS).

Eligibility Criteria

Age16 Years+
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

The study sample will be extracted from the population of patients referred to the target out-patient physiotherapy department in the normal course of events, with a complaint of neck and arm discomfort. They will be directed to the study based on the collection of clinical findings by the referrer.

You may qualify if:

  • Individuals initially reviewed by a physiotherapist (rater 1).
  • Individuals willing to attend for physiotherapy intervention.
  • Minimum 12 weeks of symptoms of neck and upper limb pain and/or paraesthesia.
  • Minimum 4/5 score on the CORE-TOS tool.

You may not qualify if:

  • Previous central neurologic injury with persisting neural deficit in the upper limb
  • Known history of peripheral neuropathy
  • Unstable angina
  • Upper limb allodynia or persistent pain sensitization
  • Systemic Inflammatory conditions
  • Those unwilling to attend for face to face consultation
