High Intensity Physical Exercise and Pain in the Neck and Upper Limb among Slaughterhouse Workers: Cross-Sectional Study

Table 2

The association between pain in neck, shoulders, elbow, and hand/wrist is estimated by Spearman’s correlation coefficients (𝑟_𝑠). All 𝑟_𝑠 are between 0.5 and 0.7 and thus considered as moderate correlations.

	Neck pain	Shoulder pain	Elbow pain	Hand/wrist pain
Neck pain	1
Shoulder pain	0.69 (𝑃<0.0001)	1
Elbow pain	0.52 (𝑃<0.0001)	0.51 (𝑃<0.0001)	1
Hand/wrist pain	0.50 (𝑃<0.0001)	0.55 (𝑃<0.0001)	0.52 (𝑃<0.0001)	1
