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).

本研究采用前测-后测单组预实验设计，招募了哈里亚纳邦安巴拉县穆拉纳一所高级中学的50名受试者。基线测量环节采用颈椎活动度量角器（Cervical Range of Motion Inclinometer），采集颈椎残疾指数（Neck Disability Index, NDI）以及颈椎各方向活动度（range of motion, ROM）数据，包括屈曲、伸展、左右侧屈以及左右旋转活动度。干预方案为连续两周、每周五天的结构化5分钟拉伸训练，针对颈椎屈曲-伸展、侧屈及旋转动作进行练习。干预结束后即刻开展后测评估，记录颈椎活动度与残疾评分的变化情况。
两周干预结束后，所有结局测量指标均观察到显著改善。平均颈椎残疾指数评分从干预前的9.78±3.84降至干预后的8.32±3.17（p=0.001），提示颈椎残疾程度有所减轻。此外，颈椎各方向活动度均出现显著提升：颈椎屈曲活动度从62.86±4.38°提升至66.12±3.76°，颈椎伸展活动度从40.08±5.0°提升至41.82±4.85°，右侧侧屈活动度从36.18±4.81°提升至38.24±4.19°，左侧侧屈活动度从36.04±4.06°提升至38.38±3.82°，右侧旋转活动度从78.24±4.30°提升至81.92±3.83°，左侧旋转活动度从79.08±3.83°提升至81.56±3.44°（所有指标p值均为0.001）。
