Summary
Prolonged sitting can cause low back pain (LBP) due to movement dysfunction. A movement control impairment (MCI) system revealed that individuals developing LBP showed poorer lumbar movement control and more asymmetry.
Area of Science:
- Biomechanics
- Musculoskeletal Health
- Ergonomics
Background:
- Prolonged sitting is a common modern lifestyle factor linked to movement-related disorders.
- Low back pain (LBP) is a prevalent issue, often exacerbated by sedentary behavior.
- Understanding the specific movement dysfunctions associated with LBP during sitting is crucial for targeted interventions.
Purpose of the Study:
- To investigate lumbar movement dysfunction using a movement control impairment (MCI) system.
- To compare movement control abilities between individuals who develop transient LBP and those who do not during prolonged sitting.
- To identify specific movement patterns indicative of LBP risk factors.
Main Methods:
- Twelve participants were divided into two groups: those who developed transient LBP during 2 hours of sitting and those who did not.
- Movement control abilities were assessed using 6 MCI tests, encompassing 12 distinct test items.
- Statistical analysis was performed to compare MCI scores and specific movement patterns between the groups.
Main Results:
- The group that developed transient LBP exhibited significantly higher mean MCI test scores compared to the non-LBP group (P=.03).
- Impaired lumbar flexion control, specifically during backward rocking, was significantly more prevalent in the LBP developer group (P<.027).
- While pelvic shifting and asymmetry were observed in both groups during trunk side-bending, significant pelvic shifting was more evident in the LBP group (P=.093).
Conclusions:
- Individuals experiencing transient LBP during prolonged sitting demonstrate poorer movement control and increased asymmetry.
- Even participants not developing LBP showed deficits in lumbar flexion and rotation, suggesting subclinical dysfunction.
- Subgroup classification based on movement control deficits is recommended for early detection of mechanical risk factors and for implementing effective health interventions.
