Kendall Versus Janda's Approach Along With Diaphragmatic Breathing Exercises in Upper Crossed Syndrome

Upper Crossed Syndrome (UCS) is a postural imbalance in the upper body characterized by shortened and tight muscles in the front and upper back, while weak muscles in the back and neck are stretched and underactive. This imbalance can lead to forward head posture, rounded shoulders, and increased spinal curves, causing pain, headaches, and reduced range of motion. The study aims to compare the effects of Kendall exercises with Janda's Approach along with Diaphragmatic breathing exercises on pain, chest expansion, craniovertebral angle, and disability in upper crossed syndrome.

About this study

This randomized clinical trial study will be conducted at Central Hospital and Anwer's Polyclinic, Sialkot. We will include 50 patients (25 in each group) of Upper Crossed Syndrome with an age range of 30-50 years, both male and female will be included. Group A will be provided Kendall Exercises with Diaphragmatic breathing exercises, and Group B will receive Janda's with diaphragmatic breathing exercises. Both interventions will be administered for 45 minutes per session, three times per week, for a total duration of six weeks. Outcome measures will include NPRS for pain, Neck Disability Index for disability, Universal goniometer for cranio vertebral angle, and a measuring tape for thoracic expansion will be used. The collected data will be analyzed in the Statistical Package for the Social Sciences (SPSS) 26.0 version. If the data is normally distributed, then a parametric if not normally distributed than a nonparametric test will be applied.

Primary outcomes

  1. NUMERIC PAIN RATE SCALE (NPRS) for pain

    Time frame: upto 6 weeks

    It is a self-reported scale that measures pain intensity on a scale from 0 (no pain) to 10 (worst possible pain). It is widely used in musculoskeletal conditions for monitoring pain levels over time. The NPRS has demonstrated high validity (r = 0.85 with VAS) and excellent test-retest reliability (ICC = 0.92-0.96). The MCID for NPRS is generally considered to be 2 points, indicating a meaningful improvement or worsening in pain perception

  2. NECK DISABILITY INDEX (NDI)

    Time frame: upto 6 weeks

    It is a validated questionnaire consisting of 10 items that assess the functional impact of neck pain on daily activities such as personal care, work, driving, and recreation. It is specific to cervical conditions. The NDI has strong content validity, with excellent internal consistency (α = 0.87) and test-retest reliability (ICC = 0.89). The MCID for NDI has been reported to range from 5 to 7 points, representing a clinically important change in neck-related disability

  3. UNIVERSAL GONIOMETER for ROM

    Time frame: Upto 6 weeks

    It is used to measure the craniovertebral angle (CVA), an objective indicator of forward head posture in individuals. A CVA less than 50° typically indicates abnormal posture. This tool shows good validity and excellent intra-rater reliability (ICC = 0.80-0.98) for cervical spine angle measurements. While an exact MCID for CVA is not firmly established, a change of 3-5 degrees is often considered clinically meaningful in postural correction studies

  4. MEASURING TAPE

    Time frame: Upto 6 weeks

    t is a simple and cost-effective tool used to assess chest expansion, which reflects thoracic mobility and respiratory function. The measurement is taken by placing the tape around the chest at the level of the fourth intercostal space during full inhalation and exhalation. It has acceptable criterion validity and demonstrates high intra-rater reliability (ICC = 0.91-0.94), making it suitable for tracking changes in chest mobility during postural or breathing interventions. The MCID for chest expansion is not universally defined, but an increase of 0.5 to 1.0 cm is generally considered clinically relevant in pulmonary and postural rehabilitation contexts
