Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
needle puncture (acupuncture) of one myofascial trigger point located within the supraspinatus muscle bilaterally. One needle will be inserted into each trigger point (total of 2 needles). They will remain within the trigger point for 20 minutes. Only one session will be required of each subject.
Intervention code [1] 283837 0
Treatment: Other
Comparator / control treatment
Sham needle procedure. The sham needle procedure involves intramuscular needling of the normal supraspinatus muscle adjacent to the trigger point locus. The needle will remain within the trigger point for 20 minutes. Only one session will be required of each subject.
Control group
Active

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects will be asked to provide signed informed consent before participating. Each subject will then be asked to fill out a confidential health questionnaire and undergo a physical examination of the cervical spine to identify any exclusionary conditions. Qualifying subjects will then be randomized into test or control groups by the research assistant and group allocation provided to the principal investigator of this study (Allocation is not concealed), who will perform all interventional procedures.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization will be conducted by using a computer random number generator.
Masking / blinding
Blinded (masking used)

Summary
Brief summary
The purpose of this study is to investigate the therapeutic effects of needle puncture (acupuncture) of myofascial trigger points in the supraspinatus muscle in the modulation of quiet standing balance. Our thesis states that central sensitization is an important underlying mechanism in the clinical manifestation of dyequilibrium. The current literature suggests that needle puncture of myofascial trigger points modulates central sensitization and thereby has the potential to restore normal balance outcomes.
