With 9.6 million U.S. workers injured at work in 2022 alone, this post breaks down the ergonomics numbers behind injuries, symptom patterns, and the interventions that actually reduce risk.
Key Takeaways
- 9.6 million workers were injured at work in the United States in 2022, according to estimates from the Survey of Occupational Injuries and Illnesses (SOII).
- 2.6 million nonfatal workplace injuries and illnesses resulted in days away from work in the United States in 2022.
- 4.4 million nonfatal workplace injuries and illnesses involving job transfer or restriction occurred in the United States in 2022.
- A meta-analysis in the journal Applied Ergonomics found that workplace ergonomic interventions can reduce musculoskeletal symptoms by about 44% on average (effect size reported across studies).
- A study in Applied Ergonomics found that an ergonomics program reduced injury rates by 20% over a 2-year period (company-level before/after comparison).
- A 2015 systematic review in the International Journal of Industrial Ergonomics found that participatory ergonomic interventions could reduce musculoskeletal symptoms and risk levels (quantified synthesis).
- A 2020 report by Staples WorkLife showed that 74% of U.S. employees believe ergonomics is important to health (survey stat).
- The same Staples WorkLife 2020 report found 61% of respondents said their workplace could improve in ergonomics (survey).
- The NIOSH publication “Workplace Solutions” recommends that employers conduct job hazard analyses for ergonomic risk factors, typically at least annually or when changes occur.
In 2022, US workers saw 9.6 million workplace injuries, and ergonomics can cut musculoskeletal symptoms nearly in half.

Directional10The global cost of work-related musculoskeletal disorders has been estimated at $89.0 billion in the European Union (EU-27) in 2010 (Eurostat/IHME synthesis commonly cited).[2]
Single source11The WHO reported that 1.71 billion people worldwide had musculoskeletal conditions in 2019.[3]
Verified12The WHO estimated musculoskeletal conditions caused 21.6% of years lived with disability (YLDs) globally in 2019.[3]
Verified13The WHO estimated musculoskeletal conditions affected 24.1% of adults worldwide in 2019.[3]
Verified14The National Safety Council (NSC) estimates that ergonomic-related injuries cost billions in the U.S. annually; OSHA-linked summaries commonly cite $20 billion-$50 billion range (NSC/Workplace ergonomics compilations).[4]
Directional15The OSHA recordkeeping standard (29 CFR 1904) requires employers to record work-related musculoskeletal disorders when they meet criteria such as days away from work or restricted work.[5]
Single source16OSHA’s Ergonomics Program standard guidance recommends that employers set up a process to identify, assess, and control ergonomic hazards, including tracking injuries and symptoms.[6]
Verified17In the United States, overexertion and bodily reaction was the most frequent type of event leading to injuries and illnesses in 2022 (BLS SOII).[7]
Verified18In 2022, BLS SOII indicates that sprains, strains, tears were the most common injury or illness nature category (BLS).[8]
Verified19In 2022, the most common body part affected in BLS SOII was the back (lower, upper, unspecified) across many injury/illness categories.[9]
Directional20In 2022, the BLS SOII estimated that 34% of cases involved the back (upper/lower) among musculoskeletal-related injuries (case category summary).[9]
Single source21The EU’s Directive 89/391/EEC requires employers to assess risks and implement preventive measures, including ergonomic risk factors.[10]
Verified22EU Directive 2002/44/EC requires risk assessment and measures for workers exposed to hand-arm vibration, an ergonomic-relevant hazard.[11]
Verified23EU Directive 90/269/EEC requires measures to reduce risks from manual handling of loads, commonly an ergonomic risk area.[12]
Verified24In the United States, OSHA requires employers covered by 29 CFR 1910.212 to provide guarding for dangerous parts, supporting safe machinery operations that often interact with ergonomic tasks.[13]
Directional25In the United States, OSHA’s ergonomic hazards guidance uses the concept of risk factors such as force, repetition, awkward postures, vibration, and contact stress (qualitative risk framework).[6]
Single sourceIndustry Trends Interpretation
Even though the U.S. incidence rate for nonfatal work injuries and illnesses fell 0.4% from 2021 to 2022 to 2.7 cases per 100 full-time workers, millions of incidents still occur each year and musculoskeletal problems remain a major burden globally, with WHO estimating 1.71 billion people affected in 2019.
