Normative value of core muscle strength using sphygmomanometer

Background:
Core muscles are crucial for ensuring stability and strength in the abdominal, trunk, and lumbopelvic regions. College students often experience lower back pain due to sedentary lifestyles, prolonged computer usage, intense study habits, and incorrect sitting postures. Core stabilization exercises are effective in strengthening deep abdominal muscles using the abdominal drawing-in maneuver (ADIM). A sphygmomanometer is frequently used to evaluate core muscle strength. The mechanical low back pain scale (MLBP) and the straight leg raise test (SLR) are two reliable diagnostic techniques used to determine the severity of mechanical low back pain.
Aim and objective:
This study aims to investigate the normative value of core strength in participants with MLBP.
Materials and Methods:
A total of 116 females participants were recruited based on inclusion and exclusion criteria. The participants had mechanical low back pain and were between 18-25 years of age. Sphygmomanometer was used to check the core muscle strength, three trials of 10 seconds and with a one minute of rest required between each trail. It took 5- 8 minutes to obtain the higher pressure reading. The baseline characteristics were calculated using KOLMOGOROV and analyzed data with SPSS software. The median with interquartile range (IQR) was used to determine the values of core strength.
Results and discussion:
A normative value of core muscle strength was observed in female participants, in the supine position, with a median rank of 65.00 with an interquartile range (IQR) of 60.00-70.00 in participants with mechanical low back pain.
Conclusion:
The study concluded that sphygmomanometer is effective for the clinical use due to its portability, comfort and cost effectiveness, and ability to provide accurate measurement of core muscle strength with abdominal drawing-in maneuver technique in participants with mechanical low back pain.

背景：核心肌群对于确保腹部、躯干和骨盆区域的稳定性和力量至关重要。大学生由于久坐的生活方式、长时间使用电脑、刻苦的学习习惯以及不正确的坐姿，常常经历下背部疼痛。核心稳定化训练通过腹式收缩动作（ADIM）有效强化深层腹部肌肉。血压计常被用于评估核心肌群的力量。机械性下背部疼痛量表（MLBP）和直腿抬高试验（SLR）是两种可靠的诊断技术，用于确定机械性下背部疼痛的严重程度。
目标与目的：本研究旨在调查机械性下背部疼痛患者核心力量的规范值。
材料与方法：根据纳入和排除标准，共招募了116名女性参与者。参与者患有机械性下背部疼痛，年龄在18-25岁之间。使用血压计检查核心肌群力量，需进行三次10秒的试验，每次试验之间休息一分钟。获取最高压力读数需要5-8分钟。使用KOLMOGOROV方法计算基线特征，并使用SPSS软件分析数据。核心力量的值使用中位数和四分位数范围（IQR）来确定。
结果与讨论：在机械性下背部疼痛的女性参与者中，仰卧位时观察到核心肌群力量的规范值，中位数为65.00，四分位数范围为60.00-70.00。
结论：研究得出结论，血压计因其便携性、舒适性、成本效益以及能够在机械性下背部疼痛患者中提供准确的腹式收缩动作技术核心肌群力量测量，因此在临床应用中是有效的。
