Researchers used a musculoskeletal model to predict joint contact forces and investigate the variations of joint contact forces due to joint impairment in 18 juvenile idiopathic arthritis patients.
This small study of healthy volunteers explored differences in the coronal biomechanics of the trunk, pelvis, hip, and knee joints, as well as gluteus medius muscle activity during walking and step down tasks.

Although this is a small study, the paper contributes to our knowledge base around the gait variations that are seen in people with chronic obstructive pulmonary disease.

"Subjects with COPD walked with less consistent organization of movement patterns of the lower extremities across walking speeds. These findings suggest the presence of neuromuscular deterioration in the locomotor system, reflecting less healthy movement patterns in subjects with COPD.”1 (p.2).
The authors comment on the role of biomechanical joint limitations, as well as other factors in the discussion, section (and they do a good job of acknowledging the study’s limitations).
The subtalar joint is a complex articulation that is often overlooked clinically, frequently ignored in favour of talocrural and midfoot mobility. But understanding the anatomy and mechanics of this joint can allow for better movement retraining through the foot, knee, hip, pelvis, and lumbar spine.
