Low back pain influences medial-lateral trunk movement variations during sit-to-stand tasks in persons with transtibial amputation.

Background: Individuals with lower-limb amputation commonly experience low back pain, which may be associated with altered movement strategies or impaired trunk control during activities of daily living, such as sit-to-stand. The aim of this study was to assess, using wearable sensors, sit-to-stand performance and trunk movement variations of persons with transtibial amputation, with and without low back pain.

Methods: Fifty-eight persons with unilateral transtibial amputation (28 with and 30 without low back pain) performed five sit-to-stand trials while wearing two inertial measurement units affixed to the thigh and sternum.

Comparing spinal loads in individuals with unilateral transtibial amputation with and without chronic low back pain: An EMG-informed approach.

Chronic low back pain (cLBP) is highly prevalent after lower limb amputation (LLA), likely due in part to biomechanical factors. Here, three-dimensional full-body kinematics and kinetics during level-ground walking, at a self-selected and three controlled speeds (1.0, 1.

Peak tibial axial acceleration during walking is related to intact-side lower limb pain in persons with unilateral transtibial amputation.

Background: Persons who undergo unilateral transtibial amputation are at an increased risk of secondary musculoskeletal joint pain and degeneration, which has been linked to excessive loading rates of the intact-side limb. Tibial axial acceleration, a feasible measure of loading rates with wearable sensors, would be clinically useful to relate to joint pain in persons with unilateral transtibial amputation.

Research Question: What is the relationship between peak tibial axial accelerations and intact-side joint pain in persons with unilateral transtibial amputation during walking?

Methods: Persons with unilateral transtibial amputation (n = 51) were separated into two groups based on the presence of intact-side limb pain (with pain: n = 16; without pain: n = 35).

Principal components analysis of postural sway in persons with unilateral lower limb amputation: A wearable sensor approach.

Standing sway assessments can detect sensory imbalances which compromise postural control. Persons with lower limb amputation (LLA) often demonstrate impaired postural control, increasing fall risk. Here, principal features of postural sway were identified in persons with unilateral LLA using a single, commercially available wearable sensor.
