The present study measured trunk muscle strength in patients with rheumatoid arthritis (RA), compared their results with those of healthy individuals, and investigated factors associated with the rising motion. The subjects were 75 female RA outpatients and 26 healthy female controls. A handheld dynamometer (HHD) was used to measure trunk muscle strength, and an RGB-D camera was used to capture images of the rising motion. Time required to perform the rising motion was significantly longer in the RA group (RA: 5.2±2.0 sec, HC: 3.8±1.1 sec; P <0.01). In terms of muscle strength in the trunk and shoulders, apart from the trunk flexion muscles, subjects in the RA group had significantly lower muscle strength during right lateral bending (P <0.01), left lateral bending (P <0.05), and in all shoulder joints (P <0.01), including during trunk extension (RA: 10.5%±3.8%, HC: 12.6%±3.2%; P <0.05). Furthermore, muscle strength during forward trunk flexion and bilateral bending was lower in Class III patients with RA than in Class I and II patients with RA. There was a correlation between diminished activities of daily living and decreased muscle strength in the trunk muscles in patients with RA, and this decrease was a causal factor in prolonged rising time.
