Ages Eligible for Study:   18 Years to 40 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Not all of the below listed criteria must be present, but some combination of two or more should be present before the participant can be deemed to have hypertonic
  • hypertonic levator scapulae musculature.
  • Anterior head carriage
  • Internally rolled shoulders
  • Occupational risk of poor upper cross posture
  • Palpable muscular tightness
  • Tenderness to palpation of the area
  • Participant complaint of pain or tightness in the area

Exclusion Criteria:

  • Participants will be excluded from this study if they have a history of a trauma that lead to marked scar tissue in the upper trapezius muscle as this would alter the surface EMG readings due to injured and altered tissue.
