The goal of this clinical trial was to find out whether a self-applied neck mobilization technique (called self-SNAGs) or neck strengthening exercises (dynamic isometric exercises) works better to reduce pain and improve daily function in computer professionals aged 25-45 years who had long-lasting mechanical neck pain.

The main questions it aimed to answer were:

• Does self-SNAG treatment reduce neck pain more than strengthening exercises?
• Does self-SNAG treatment improve neck-related daily activities more than strengthening exercises?

Researchers compared self-SNAG exercises with dynamic isometric neck exercises to see which approach led to greater pain relief and better function over six weeks.

Participants were asked to:

• Perform either self-SNAG neck movements using a towel or neck-strengthening exercises using elastic bands.
• Do the exercises five days per week for six weeks.
• Follow ergonomic advice for proper posture during computer work.
• Complete pain and disability questionnaires before and after the program.

Inclusion Criteria:

• Participants' ages ranged from 25 to 45 years.
• Having chronic mechanical neck pain persisting for at least 3 months.
• Computer users of at least 4 to 5 hours daily for greater than 3 years.
• Understand and be able to perform the indicated exercises well.
• Cooperation in the study with voluntary participation.

Exclusion Criteria:

• Prior history of musculoskeletal neck disorders, trauma, fracture, inflammation, malignancy, active infection, any neurological disorders or deficits, and any spinal surgeries.
• Acute mechanical neck pain
• Non-cooperation in the study,
