Research profile

Concussion injuries are characterised by a broad range of symptoms such as headache, dizziness, neck pain, cognitive and emotional disturbance.

physio_ewan kennedy 2019 B+W 418A particular challenge is that concussion injuries can injure the brain, vestibular and visual systems, the neck, and more – all of which are capable of contributing to symptoms.

To help individuals with persistent post-concussion symptoms effectively, our research team think it is important to understand the underlying sources of symptoms and tailor treatment appropriately.

Our research has highlighted that the neck can contribute to persistent post-concussion symptoms, and frequently does so. The neck is known to cause headaches, dizziness and neck pain, which can be effectively treated with physiotherapy.

As our understanding of concussion injuries improves, we are working to translate this understanding into effective health services

This project area is led by Dr Ewan Kennedy

Characteristics of  neck problems in people with persistent post-concussion symptoms

In collaboration with local Physiotherapists and ACC concussion service providers we have been working on studies to describe the contribution of the neck to persistent post-concussion symptoms, with particular attention to headaches, dizziness and/or neck pain.
