A 52-year-old female patient presents to your clinic with a 4-week history of mid-back pain and stiffness. The patient reports that the pain started after a long day of gardening and has progressively worsened. She has trouble twisting her torso to the right and has noticed muscle tightness on the left side of her mid-back. Physical examination reveals tenderness over the left paraspinal muscles at the T7 vertebral level, restricted right rotation, and restricted right lateral flexion which improves with extension. Based on these findings, you diagnose the patient with a specific thoracic somatic dysfunction. You decide to use the High-Velocity Low-Amplitude (HVLA) technique for treatment. Given the physical examination findings, which thoracic somatic dysfunction diagnosis is most likely, and in which direction should the HVLA force be applied to effectively treat the patient’s somatic dysfunction?
