Dataset of Effectiveness of 5 minutes interclass stretching routine on flexibility of neck muscles among school going children

A pre-test–post-test single-group pilot experimental design was implemented with 50 participants recruited from a senior-secondary school in Mullana, Ambala, Haryana. Baseline measurements included the Neck Disability Index (NDI) and cervical range of motion (ROM) in flexion, extension, lateral flexions (right and left), and rotations (right and left) using a Cervical Range of Motion Inclinometer. The intervention protocol consisted of a structured 5-minute stretching routine targeting neck flexion–extension, side flexion, and rotation exercises, performed five days a week for two consecutive weeks. Post-intervention assessments were conducted immediately after the program to document changes in flexibility and disability scores.
Following the 2-week intervention, significant improvements were observed across all outcome measures. The mean NDI score decreased from 9.78 ± 3.84 pre-intervention to 8.32 ± 3.17 post-intervention (p = 0.001), indicating reduced neck disability. Additionally, cervical ROM increased significantly in all directions: neck flexion improved from 62.86 ± 4.38° to 66.12 ± 3.76°, neck extension from 40.08 ± 5.0° to 41.82 ± 4.85°, right lateral flexion from 36.18 ± 4.81° to 38.24 ± 4.19°, left lateral flexion from 36.04 ± 4.06° to 38.38 ± 3.82°, right rotation from 78.24 ± 4.30° to 81.92 ± 3.83°, and left rotation from 79.08 ± 3.83° to 81.56 ± 3.44° (all p = 0.001).
