Work-Related Musculoskeletal Disorders (MSDs)
MSDs occur when the physical capabilities of the worker do not match the physical requirements of the job. They are caused by job activities and conditions, like lifting heavy objects, repetitive motions, and work in confined areas.
MSDs are common in construction.
- MSDs are injuries and disorders of the soft tissues (muscles, tendons, ligaments, joints, and cartilage) and nervous system.
- They can affect nearly all tissues, including the nerves and tendon sheaths, and most frequently involve the arms and back.
- MSDs are the leading cause of disability for people in their working years.
- Complaints about back, knee, and shoulder/upper arm are the most prevalent among construction workers.
Studies indicate upper limb and shoulder MSDs were related to manual handling, work repetitiveness, psychosocial demands, job dissatisfaction, gender, and physical unfitness.
Construction workers have an increased risk of these injuries in the following instances:
- when carrying heavy loads
- twisting hands or wrist
- stretching to work overhead
- using certain types of tools
- using vibrating tools or equipment
