“…Alternative means for acquiring temporal, spatial, kinematic, and kinetic data may offer the means to assess this possibility. Portable systems that consist of sensors for tracking body movement in the free-living environment are now available and may be used to collect gait mechanics outcomes [160][161]. The use of such systems in conjunction with traditional laboratory-based equipment may allow for the assessment of function as well as activity and/or participation [162], enhancing our understanding of how prosthetic interventions are used across a variety of environmental conditions.…”

“…Although traditional biomechanists may have access to motion analysis laboratories, few may have the space to establish obstacle courses or include stairs and inclines within the available capture volume. Perhaps with the advancement of portable instrumentation systems [160][161], evaluation of environmental barriers in a user's natural environment may be possible. As an alternative, investigators may consider incorporating less sophisticated measures of environmental obstacle negotiation, such as timed stair tests [177] or standardized obstacle courses [178][179], into study protocols as a way to measure these activities.…”

Abstract-Microprocessor-controlled prosthetic knees (MPKs) have been developed as an alternative to non-microprocessorcontrolled knees (NMPKs) to address challenges facing individuals with lower-limb loss. A body of scientific literature comparing MPKs and NMPKs exists but has yet to be critically appraised. Therefore, we conducted a systematic review to examine outcomes associated with the use of these interventions among individuals with transfemoral limb loss. A search of biomedical databases identified 241 publications, of which 27 met the inclusion and exclusion criteria and were reviewed for methodological quality and content. We developed 28 empirical evidence statements (EESs) in 9 outcome categories (metabolic energy expenditure, activity, cognitive demand, gait mechanics, environmental obstacle negotiation, safety, preference and satisfaction, economics, and health and quality of life) based on findings in the literature. The level of evidence supporting these EESs varied due to quantity, quality, and consistency of the results. EESs supported by a moderate level of evidence that noted significant differences between MPKs and NMPKs were derived in five of the nine outcome categories. The results from this review suggest that evidence exists to inform clinical practice and that additional research is needed to confirm existing evidence and better understand outcomes associated with the use of NMPKs and MPKs.Key words: amputation, artificial limb, function, gait, knee, microprocessor, outcome, preference, rehabilitation, safety.

“…Another limitation is that parts of both horse and rider's bodies may be hidden from view, restricting the analysis that can be accurately performed (Greve & Dyson 2012). Bergmann, Mayagoitia, and Smith (2009) reported that body-worn, inertial motion sensors are a practical, non-constraining alternative to optical motion analysis for the measurement of lower-extremity joint angles. Ease of setup and portability makes them suitable for use by clinicians and researchers outside the laboratory environment.…”

“…Sensor drift was negligible over the short duration of each trial. Bergmann et al [23] showed that mean motion sensor orientation measurements were strongly correlated with joint angle measurements from an optical tracking device (correlation range: 0.93-0.99, maximum joint ranges of motion: 49°-92°), and we verified the angle measurement accuracy using an inclinometer; in addition, we verified the accuracy of the motion sensor during the rise against a video recording of a single subject.…”

Comparison of seat, waist, and arm sit-to-stand assistance modalities in elderly population

Abstract-The ability to perform a sit-to-stand (STS) motion is important for ambulatory adults to function independently and maintain daily activities. Roughly 6% of community-dwelling older adults experience significant difficulties with STS, a major risk factor for institutionalization. While mechanical STS assistance can help address this problem, full dependence on STS assistance provided by devices such as lift chairs can lead to atrophy of the leg muscles. We investigated the mechanics of assisted STS motion in order to better understand how loadsharing STS mechanisms may facilitate STS motions while still requiring activation of the leg muscles. Experiments were conducted with 17 nondisabled older adults performing unassisted and assisted STS rises with grab bar, arm, seat, and waist assistance. Each mode of rise was evaluated based on a subject questionnaire and key biomechanical metrics relating to stability, knee effort reduction, and rise trajectory. Results show that the seat-and waist-assist modes provide statistically significant improvements in stability metrics and reductions in required knee torques over unassisted rises and bar assistance. The assists most preferred by the subjects were the seat and bar assists. Overall, our results favor a seat-assisted STS modality for nonclinical applications and indicate further testing of this modality with a clinical population.
