Modeling Post-traumatic Pain and Recovery: The SYMBIOME Longitudinal Cohort Study

The Systematic Merging of Biology, Mental Health and Environment (SYMBIOME) Longitudinal Databanking Project

This study will explore the contribution of stress-system activity to pain and functional disability in the acute stage of traumatic musculoskeletal injury, and to the maintenance of symptoms after 3, 6 and 12 months post-injury.

Purpose: The purpose of this protocol is to establish a longitudinal database of data collected from people having experienced an acute traumatic injury to their musculoskeletal system. This includes injuries commonly considered 'non-catastrophic' or 'minor' soft tissue injuries such as whiplash, low back injuries, sports or slip and fall-type injuries that result in sprain/strain of muscle, tendon, ligament or other such soft tissues. Uncomplicated bony fractures (those that are managed through casting only, non-surgical) will also comprise this cohort. The data will include biological specimens, psychological and cognitive profiles, and social/environmental indicators. This protocol represents the start of the SYStematic Merging of Biology, Mental health and Environment (SYMBIOME) project from the emerging Solving Traumatic pain and disability through Advanced Research Translation (START) research group centred at Western. Over time, this database will allow rich exploration of complex interactions between biology, psychology and environment as they relate to the resolution of traumatic pain and disability, or similarly the persistence thereof. Additional research ethics board (REB) applications will be submitted as those projects are ready to be formally conducted.

Inclusion Criteria:

Eligible participants:

1. Will be aged 18 years or older
2. Will be able to speak and understand conversational (grade 6) English
3. Will be free of cognitive impairments that would interfere with ability to follow directions (e.g. diagnosed Alzheimer's Dementia, Down's Syndrome)
4. Will be free of neuromuscular disorder that impairs mobility (e.g. stroke, multiple sclerosis, cerebral palsy, ALS)
5. Will be free of active malignancies for the past 5 years
6. Will be free of systemic inflammatory conditions, including rheumatoid or psoriatic arthritis, scleroderma, or systemic lupus erythematosus
7. Will not have been diagnosed with a concussion over the previous 6 months (including the current injury)
8. Will not have been hospitalized overnight over the previous 6 months (including the current injury)
9. Will not have taken steroid-based medications (either prescribed or self-administered) over the previous 6 months
10. Will not have required surgical correction/relocation as a result of the trauma (e.g. open reduction/internal fixation of a fracture). -
