Table 3 Baseline characteristics of pain, movement control of the low back, physical fitness, and work-related factors

From: Neuromuscular exercise reduces low back pain intensity and improves physical functioning in nursing duties among female healthcare workers; secondary analysis of a randomised controlled trial
