Effects of different baggage carrying methods on walking while wearing an arm sling in simulated hemiplegic stroke patients

[Purpose] We aimed to clarify the effects of different baggage carrying methods on the movement of the trunk and pelvis while walking with an arm sling in simulated hemiplegic stroke patients. [Participants and Methods] The participants were 14 healthy young adults. Measurements were obtained using a three-dimensional motion analysis device in the following order: normal walking, walking with an arm sling on the upper left limb, walking with baggage on the right side, vertical walking, and diagonal walking. The range of motion of the trunk and pelvis during one walking cycle was analyzed. [Results] The range of motion of the lateral tilt of the pelvis significantly differed between normal and vertical walking, as well as between normal walking and diagonal walking. A significant difference was observed in the range of movement in pelvic rotation during the three walking cycles—walking with baggage, vertical walking, and diagonal walking. The range of movement in pelvic rotation was seemingly smaller under other conditions compared to that in normal walking. [Conclusion] It was shown that walking with restrictions on the upper limbs, such as wearing an arm sling or carrying baggage, may impose slight restrictions on the lateral tilt as well as on the rotation of the pelvis.
