“…Similar to previous studies using motion analysis laboratories, the data from this study indicate that patients with unilateral TKA have asymmetrical movement patterns during the rehabilitation phase following surgery 1,2,5 . For example, using a stair case instrumented with force plates and an 8-camera motion analysis system, Mandeville and colleagues 27 demonstrated that patients have reduced surgical knee extension moments during stair climbing at six months following surgery compared to a healthy age-matched control group.…”

“…For example, using a stair case instrumented with force plates and an 8-camera motion analysis system, Mandeville and colleagues 27 demonstrated that patients have reduced surgical knee extension moments during stair climbing at six months following surgery compared to a healthy age-matched control group. Stacoff and colleagues 5 also used a motion analysis lab to examine inter-limb loading symmetry during stair ascent and descent for patients 1–3 years after unilateral TKA. Their findings were that patients demonstrated asymmetry of loading, characterized by decreased loading on the surgical limb compared to the non-surgical limb during weight acceptance phase of stair ascent and descent.…”

“…Movement symmetry following TKA has often been measured in motion analysis laboratories equipped with cameras, electromyographic signal recording systems, and/or force platforms in a confined motion capture area 2,5–7 . In addition, motion analysis systems have been used for providing feedback to patients during movement pattern re-training after lower limb joint surgeries 8–10 .…”

Background The purpose of this investigation was to examine movement symmetry changes over the first 26 weeks following unilateral total knee arthroplasty in community environments using skin-mounted tibial accelerometers. Comparisons to healthy participants of similar age were also made. Methods Patients (N = 24) with unilateral knee osteoarthritis (mean (SD), 65.2 (9.2) years) scheduled to undergo total knee arthroplasty and a control group (N = 19 healthy people; mean (SD), 61.3 (9.2) years) were recruited. The total knee arthroplasty group participated in a standardized course of physical rehabilitation. Tibial acceleration data were recorded during a Stair Climb Test and 6-Minute Walk Test. Tibial acceleration data were reduced to initial peak acceleration for each step. An inter-limb absolute symmetry index of tibial initial peak acceleration values was calculated. Findings The total knee arthroplasty group had greater between limb asymmetry for tibial initial peak acceleration and initial peak acceleration absolute symmetry index values five weeks after total knee arthroplasty, during the Stair Climb Test and the 6-Minute Walk Test. Interpretation Tibial accelerometry is a potential tool for measuring movement symmetry following unilateral total knee arthroplasty in clinical and community environments. Accelerometer-based symmetry outcomes follow patterns similar to published measures of limb loading recorded in laboratory settings.

“…A conclusion drawn from the presented research is that bpm determines values of the vGRF, varying from 1.12 to 1.54 BW when stepping up the bench to 2.7 BW when stepping down. The vGRF values obtained by the researchers mentioned above were similar to those observed during natural gait and stair climbing [19]. It can be assumed that values of the vGRF do not lead to injuries in people performing step workout.…”

The aim of this research was to determine the features of a step workout technique which may be related to motor system overloading in step aerobics. Subjects participating in the research were instructors (n = 15) and students (n = 15) without any prior experience in step aerobics. Kinematic and kinetic data was collected with the use of the BTS SMART system comprised of 6 calibrated video cameras and two Kistler force plates. The subjects' task was to perform basic steps. The following variables were analyzed: vertical, anteroposterior, and mediolateral ground reaction forces; foot flexion and abduction and adduction angles; knee joint flexion angle; and trunk flexion angle in the sagittal plane. The angle of a foot adduction recorded for the instructors was significantly smaller than that of the students. The knee joint angle while stepping up was significantly higher for the instructors compared to that for the students. Our research confirmed that foot dorsal flexion and adduction performed while stepping up increased load on the ankle joint. Both small and large angles of knee flexion while stepping up and down resulted in knee joint injuries. A small trunk flexion angle in the entire cycle of step workout shut down dorsal muscles, which stopped suppressing the load put on the spine.

“…In descending the stairs, the typical double waveform was no longer present. After the first maximum the curves progressed in large variations, showing curves with and without a second maximum (Fz4) (see also [32]). Generally, the variability increased with the increase in stair inclination.…”
