Dry Cupping Therapy and Muscle Energy Technique on Upper Crossed Syndrome

Condition(s) studied

Investigational drug(s) / intervention(s)

combined therapy teatment: 19 subjects received combined dry cupping therapy, Muscle energy technique, and conventional physical therapy for eight weeks. 1. Dry cupping was applied to the regional hypertonic target sites. Standard plastic cups ranging from 25 to 50 mm were placed directly over each subject's levator scapulae trigger point (SI-14) and upper trapezius trigger point (GB-21) bilaterally. The treatment duration was set at exactly 8 minutes per session. 2. Muscle Energy Technique The Post-Isometric Relaxation (PIR) manual protocol targeted the hypertonic muscles of the upper crossed syndrome quadrant, including the upper trapezius, levator scapulae, sternocleidomastoid, scalenes, and suboccipital groups. Participants were placed in a supine position on the treatment table with their head free from the edge of the plinth, supported by the physical therapist. 3. conventional physical therapy treatment

Study summary

This study evaluated and compared the therapeutic efficacy of combining Dry Cupping therapy with the Muscle Energy Technique (MET) against each intervention applied independently, focusing on three core parameters: Neck Disability Index (NDI), Craniovertebral Angle (CVA), and Sagittal Shoulder-C7 Angle (SSA).

Eligibility

Primary outcome measure(s)

• Neck Disability Index (NDI) — At baseline and re assessed following 8 weeks
  Perceived functional limitations resulting from regional impairment were measured using the validated Arabic version of the NDI questionnaire. This instrument evaluates 10 clinical sections (including activities of daily living, concentration, and pain profiles) scored from 0 to 5 per item, yielding a cumulative score out of 50. Higher aggregate indices represent greater functional disability.
• craniovertebral angle (CVA) — At baseline and re assessed following 8 weeks
  This biomechanical index reflects the architectural severity of forward head posture. It is defined as the angle formed between a horizontal line drawn through the spinous process of C7 and an intersecting line extending from the tragus of the ear to the C7 landmark. CVA was measured using precision digital photogrammetry via the Kinovea software application.
• Sagittal Shoulder-C7 Angle (SSA) — At baseline and re assessed following 8 weeks
  This geometric marker quantifies shoulder roundedness and anterior protraction. It is formed by the intersection of a horizontal reference line passing through the lateral aspect of the acromion with a line drawn from the C7 spinous process to the lateral acromion. SSA was measured using precision digital photogrammetry via the Kinovea software application.
