Ergonomic compatibility between sewing workstation and Bangladeshi apparel workers

Area of Science:

• Ergonomics
• Occupational Health
• Anthropometry

Background:

• Prolonged sitting and awkward postures in sewing operations contribute to musculoskeletal disorders (MSDs).
• Existing sewing furniture may not align with the anthropometric characteristics of sewing operators.

Purpose of the Study:

• To assess the compatibility between sewing furniture dimensions and the anthropometry of sewing operators.
• To identify design discrepancies in sewing workstations contributing to MSDs.

Main Methods:

• Collected 13 anthropometric measurements from 368 sewing operators.
• Compared operator anthropometry with standard sewing furniture dimensions.
• Utilized statistical analysis to identify significant variations and mismatches.

Main Results:

• Significant anthropometric differences were observed between male and female participants, with males generally having larger measurements (excluding hip breadth).
• A substantial mismatch was found between operator anthropometry and sewing furniture dimensions (e.g., seat height, width, depth; table depth).
• Statistical analysis revealed significant variations from existing sewing machine dimensions.

Conclusions:

• The incompatibility between sewing workstations and operator anthropometry is a primary cause of MSDs among sewing operators.
• Recommended guidelines for designing ergonomic sewing workstations are proposed.
• Findings can inform manufacturers and importers in setting provisions for sewing machines.
