Pre-placement examinations for newly recruited health care support staff.
Joyce Yuk Ping Wong
PMID 33815024WHAT IT FOUND
Newly recruited health support staff had lower handgrip strength than local norms, but weak grip did not predict musculoskeletal symptoms.
Only lower bilateral lifting capacity was significantly associated with current symptoms, suggesting pre-placement exams should prioritize functional lifting tests over grip strength.
Key findings
01Weak handgrip strength was not significantly associated with reported musculoskeletal symptoms.
02Subjects with musculoskeletal symptoms had significantly lower bilateral lifting force than those without.
03Only bilateral lifting force was significantly associated with musculoskeletal symptoms in regression analysis.

What it does not show
Convenience sampling from a single hospital cluster limits generalizability. The cross-sectional design cannot establish causality between physical capacity and symptoms. Self-reported symptoms may be subject to recall bias. Participants were new to their roles, so long-term occupational impacts were not assessed.
Declared interests
The authors declared no potential conflicts of interest and received no financial support for the research.
The easy way to misread this
Do not assume that normalizing grip strength will reduce musculoskeletal injury risk. The study found no association between weak grip and symptoms, whereas lifting capacity was significantly linked to current complaints. Focusing on grip strength alone may miss the relevant physical deficits in this population.
