Muscles of the Vertebral Column

Muscles of the Vertebral Column

The back muscles that lie deep into the thoracolumbar fascia are called intrinsic or true back muscles. These muscles are divided into four layers: superficial, intermediate, deep, and deepest layers.
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...

Area of Science:

Occupational Health
Rehabilitation Medicine
Ergonomics

Background:

Work-related musculoskeletal disorders (WRMSD) are a primary cause of occupational illness.
Nursing assistants and service forces are particularly vulnerable to low back pain due to manual labor demands.

Purpose of the Study:

To compare the effectiveness of corrective exercise training versus ergonomic principles training for low back pain.
To evaluate outcomes in nursing assistants and service forces.

Main Methods:

A nonrandomized clinical trial involved 75 staff with low back pain.
Participants were assigned to corrective exercise, ergonomic training, or a control group.
Pain intensity and disability were assessed pre- and post-8-week interventions.

Main Results:

Corrective exercise group showed significantly lower pain intensity (3.8 ± 1.5) compared to ergonomic (4.7 ± 1.4) and control (5.5 ± 1.7) groups (P=0.001).
The corrective exercise group also reported significantly lower disability scores (17.3 ± 9.6) than the ergonomic (21.8 ± 12.6) and control (25.3 ± 11.2) groups (P<0.001).

Conclusions:

Both corrective exercises and ergonomic training reduce low back pain and disability.
Corrective exercise training demonstrates superior effectiveness compared to ergonomic principles training for low back pain management.
