What do I do with patients that hurt all over? Why do carpal tunnel symptoms seem to keep coming back? This course is designed to assist practicing therapists in identifying key features of thoracic outlet syndrome and provide guidance for evaluating these patients using a manual therapy approach. Obtaining a pertinent history and performing a thorough physical examination will give therapists the tools to identify disputed neurogenic TOS and prioritize the patient’s impairments.

    Chapters & learning objectives

    Types of Thoracic Outlet Syndrome

    1. Types of Thoracic Outlet Syndrome

    This chapter covers the anatomy of the thoracic outlet and the types of thoracic outlet syndrome (TOS). It is important to differentiate vascular versus neurogenic TOS to identify the most appropriate therapy intervention.

    Clinical Testing for TOS

    2. Clinical Testing for TOS

    This chapter identifies key information to glean from the patient history, as well as instruction on how to perform a cervical screen and clinical testing for disputed neurogenic TOS. Therapists will develop an understanding of a cluster of tests needed to confirm the diagnosis of TOS.

    1st & 2nd Rib Mobility Assessment

    3. 1st & 2nd Rib Mobility Assessment

    This chapter covers the mechanics of the 1st and 2nd ribs, reviews how motion occurs at both the costovertebral and costotransverse joints, followed by instruction in how to assess 1st and 2nd ribs mobility. This is critical for TOS patients, as an elevated 1st rib can contribute to brachial plexus irritation at both the scalene triangle and costoclavicular space.
