Various exercise programs are used to treat lateral abdominal muscle (LAM) impairments in people with low back pain. Factors comprising these programs include exercise type, session time, frequency, and program duration. However, specific clinical guidance about optimal exercise prescription is lacking.
To perform a dose-response analysis on exercise prescription variables for LAM thickness and activation as measured by ultrasound imaging.
Systematic review METHOD: Databases were searched from their inception for studies examining the association between exercise interventions and LAM thickness/activation measured by ultrasound imaging in healthy individuals. Risk of bias was assessed using the Joanna Brigg's Institute critical appraisal tools. For each muscle, subgroup analyses were performed to determine the dose response of exercise prescription variables for LAM thickness and activation. Where there was insufficient data for subgroup analyses, data was narratively synthesised.
Fourteen studies comprising 395 participants were included. Statistical and narrative synthesis revealed specific local abdominal exercises, programs from four weeks duration, three sessions per week and sessions of ≥30 min were associated with greatest improvements to LAM thickness. Only the variables exercise type, program duration and session frequency showed a significant between groups difference for the subgroup analysis. The main limitation was inability to perform subgroup analyses for all variables across all muscles measured at rest and during contraction, due to non-reporting of data.
This review provides preliminary guidance to practitioners on how the LAM respond to different exercise dosages. Future research should trial these findings.
各种运动方案被用于治疗腰痛患者的侧腹肌（LAM）损伤。这些方案的组成因素包括运动类型、疗程时间、频率和方案持续时间。然而，关于最佳运动处方的具体临床指导尚缺乏。
对超声成像测量的 LAM 厚度和激活的运动处方变量进行剂量反应分析。
系统综述
从数据库成立之初开始搜索，以调查超声成像测量健康个体中运动干预与 LAM 厚度/激活之间关联的研究。使用 Joanna Brigg's Institute 批判性评价工具评估偏倚风险。对于每块肌肉，进行亚组分析，以确定运动处方变量对 LAM 厚度和激活的剂量反应。对于没有足够数据进行亚组分析的情况，进行叙述性综合。
纳入了 14 项研究，共 395 名参与者。统计和叙述性综合表明，特定的局部腹部运动、为期四周的方案、每周三次和每次 30 分钟以上的疗程与 LAM 厚度的最大改善相关。仅运动类型、方案持续时间和疗程频率这三个变量在亚组分析中显示出组间差异有统计学意义。主要限制是由于数据未报告，无法对所有在休息和收缩期间测量的肌肉的所有变量进行亚组分析。
本综述为从业者提供了关于 LAM 对不同运动剂量的反应的初步指导。未来的研究应检验这些发现。
