Recruitment & Eligibility

• Status: Recruiting
• Sex: Female
• Target Recruitment: 48

Inclusion Criteria

Participants need to present with fixations in the region of the thoracic spine (Nyberg and Russel-Smith 2013).
-The participants cannot be younger than 18 years of age as this eliminates the requisite for consent from a parent or legal guardian.
-Participants cann\ot be older than 45 years of age because there is an increased likelihood of pathologies such as degeneration and, consequently, may alter the outcomes of the study (Walker et al. 2014).

Exclusion Criteria

-Participants experiencing any pain in the region of the thoracic spine (Minarini et al. 2018).
-Individuals who have taken any drugs that alter skeletal muscles in the last four weeks need to be excluded because it may skew results recorded by the surface electromyography (sEMG) instruments. For example, Norflex (Kruk and Pycock 1991).
-Exclude participants who have receive manual therapy (i.e. manipulation, mobilisation or any soft tissue treatment) on the thoracic spine in the last 4 weeks. This avoids the effects of previous interventions from altering results recorded during the study.
-Individuals who have been diagnosed with clinical contraindications to spinal joint mobilisation identified during a case history and/or physical exam need to be excluded from the study and referred to an appropriate medical discipline to assist with the condition. These contraindications include acute inflammation, Pott’s Disease, malignancy, hypermobility, neurological deficits, fractures, osteoporosis, rheumatoid arthritis during the acute phase, Paget’s Disease, Ankylosing Spondylitis during the inflammatory phase, Sheuermann’s Disease during phase 1 (Duarte et al. 2014), vertebral artery insufficiency, scoliosis, history of surgery and trauma and spinal cord insufficiency (Konin and Jessee 2012).
-Individuals with contraindications to sEMG at the region of electrode placement need to be excluded as well. These contraindications include psoriasis, skin rashes, open wounds or any skin irritations
-Exclude individuals with a skinfold thickness that is higher than 19mm. The presence of adipose tissue alters the ability to take accurate muscle activity readings (Baniqued et al. 2016).
-If participants cavitate when receiving the spinal mobilisation, they will not be excluded from the study. Bergmann and Peterson (2011) established that any form of manual therapy that causes joint separation to overcome the fluid tension in to produce a joint cavitation..
