Summary

This randomized controlled trial investigates the effects of biofeedback-guided training versus conventional therapy on muscle strength and postural alignment in patients with Upper Cross Syndrome. The study includes adults aged 25-45 years meeting diagnostic criteria for UCS, such as weak deep cervical flexors, restricted cervical ROM, forward head posture, increased thoracic kyphosis, and chronic neck pain \>3 months. Participants are divided into two groups: Group A biofeedback training and Group B conventional therapy, receiving 12 sessions over 4 weeks ,3sessions/week. Assessments are conducted at baseline, post-1st session, and weekly intervals using standardized measures.The study aims to compare the efficacy of biofeedback-guided training in improving strength and posture in UCS patients.

Eligibility

Min Age: 25 YearsMax Age: 45 Years

Inclusion Criteria6

• Adults aged 25-45 years with both genders.
Individuals meeting the following diagnostic criteria for upper cross syndrome will be included:
Reduced strength of deep cervical flexors = unable to maintain pressure beyond 22-24 mm Hg (assessed via cranio-cervical flexion test).
Limited cervical range of motion (Flexion: \< 80 degrees, Extension: \< 70 degrees, Rotation: \< 90 degrees on both sides, Lateral Flexion: \< 20 degrees)
Postural deviations: forward head posture (CVA \<50 degrees), increased thoracic kyphosis (via flexi curve \>45 degrees).
Neck pain with a duration of over 3 months

Exclusion Criteria4

• History of recent neck surgery or injury.
Patients with neurological disorders affecting muscle tone.
Involvement in other physical therapy programs focused on UCS.
Diagnosed musculoskeletal condition that could impact muscle performance.

Interventions

OTHERBio feedback training

Hot Pack: Applied for 10 minutes, mild warmth sensation to relax muscles and prepare for exercise. 1\. BPU (Biofeedback Pressure Unit): performed at 5 pressure levels (22, 24, 26, 28, 30 mmHg). Each level involves a 10-second hold, with 30 seconds rest between levels. Targeted muscles: * Deep Cervical Flexors (Capitus Longus, Capitus Colli). * Rhomboids * Trapezius Total duration (BPU): 20 minutes/session, performed 3 times/week.

OTHERconventional exercise program

Hot Pack: Applied for 10 minutes, mild warmth sensation to relax muscles and prepare for exercise. EXERCISE PROGRAM: * 1\. Supine: Neck curl with Chin Tucks (Deep Cervical Flexors Capitus Longus, Capitus Colli): 10 reps/session, holding each for 5 seconds. * 2\. Sitting: Chin tuck with Head pushing against palm. * 3\. Chin Up (Middle and Lower Trapezius): 10 reps/session, holding each for 5 seconds. * 4\. Scapular Squeezes (Rhomboids): 2-3 sets of 10 reps/session, holding each for 5 seconds• 5. Doorway Pectoral Stretch (pect major) 2-3 reps, 30 sec hold (36)Total duration: 20 minutes/session, performed 3 times/week.
