“…Most of the studies were implemented offline with very few real-time data either from the healthy subjects or subjects with motor-control and functional disorders [3,4,9,12,13,17]. Sellas et al [3] reported a MD ± Std of 34 ± 25 ms and 19 ± 36 ms for IC and TO respectively in control subjects and 33 ± 41 ms and 13 ± 38 ms for IC and TO respectively in transtibial amputees.…”

“…However, they are susceptible to mechanical failure, have generally poor durability and low cosmetic acceptance [7]. Among wearable sensors, accelerometers and gyroscopes are being deployed at different body locations for long-term monitoring of human gait [3,[6][7][8][9][10][11][12][13]. Recent advancements allow these sensors to be miniaturized, with faster processing capability and higher memory capacities to support outdoor applications [9].…”

Abstract-Lower extremity amputees suffer from mobility limitations which will result in a degradation of their quality of life. Wearable sensors are frequently used to assess spatiotemporal, kinematic and kinetic parameters providing the means to establish an interactive control of the amputee-prosthesisenvironment system. Gait events and the gait phase detection of an amputee's locomotion are vital for controlling lower limb prosthetic devices. The paper presents an approach to real-time gait event detection for lower limb amputees using a wireless gyroscope attached to the shank when performing level ground and ramp activities. The results were validated using both healthy and amputee subjects and showed that the time differences in identifying Initial Contact (IC) and Toe Off (TO) events were larger in a transfemoral amputee when compared to the control subjects and a transtibial amputee (TTA). Overall, the time difference latency lies within a range of ± 50 ms while the detection rate was 100% for all activities. Based on the validated results, the IC and TO events can be accurately detected using the proposed system in both control subjects and amputees when performing activities of daily living and can also be utilized in the clinical setup for rehabilitation and assessing the performance of lower limb prosthesis users.

“…A lightweight (300 g) portable recorder was placed on the waist belt, with four miniature gyroscopes (ADXRS150, Analog Devices Inc., Munich, Germany) attached to each calf and thigh with Velcro. This system is easy to use and shows good agreement with a gait analysis laboratory reference system and the HHS [10].…”

Purpose The aim of this study was to determine outcomes of total hip replacement (THR) with the Lemania cemented femoral stem. Methods A total of 78 THR patients were followed and compared to 17 "fit", healthy, elderly and 72 "frail" elderly subjects without THR, using clinical outcome measures and a portable, in-field gait analysis device at five and ten years follow-up. Results Forty-one patients (53 %), mean age 83.4 years, available at ten years follow-up, reported very good to excellent satisfaction. Mean Harris Hip and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores were 81.2 and 10.5 points, respectively, with excellent radiological preservation of proximal femur bone stock. Spatial and temporal gait parameters were close to the fit group and better than the frail group. Conclusions Lemania THR demonstrated very good, stable clinical and radiological results at ten years in an older patient group, comparable to other cemented systems for primary THR. Gait analysis confirmed good walking performance in a real-life environment.

Background: Walking aids are often introduced to older adults to enable independent mobility. Single-point canes are the most common device used. Benefits are tempered by research suggesting that walking aids increase fall risk. A better understanding of the effect of walking aid use on gait performance is required. Objective: To evaluate differences in the effect of initial single-point cane use on gait between younger (YAs) and older adults (OAs). Design: Cross-sectional. Setting: Community-dwelling. Participants: Twenty-six YAs (mean age ± standard deviation [SD]: 23.7 ± 2.8 years) and 25 OAs (mean age ± SD: 70.8 ± 14.1 years) participated. Inclusion criteria were 18 to 35 years of age for YAs or ≥50 years for OAs, be able to ambulate unassisted, and without any condition affecting mobility. Interventions: Not applicable. Main Outcome Measure(s): Gait velocity and stride time variability under different walking path configurations (straight path, Groningen Meander Walking Test, Figure-of-8 Walk Test) and conditions (unassisted walking, walking with a single-point cane, and walking with a single-point cane while completing a cognitive task) were recorded in a laboratory. The arithmetic task of subtracting 1s from 100 was used as the secondary cognitive task. Data analysis included separate three-way mixed analyses of variance (ANOVAs; path/condition/group). Results: There was a statistically significant two-way interaction between walking path and condition for velocity (P < .001, ω 2 = 0.03) and stride time variability (P = .032, ω 2 = 0.02). In addition, a significant main effect of group was also observed (velocity: P = .004, ω 2 = 0.07; stride time variability: P = .001, ω 2 = 0.09). Conclusions: Using a single-point cane decreased velocity and increased stride time variability in both YAs and OAs. However, the cognitive load and effect on gait of initial cane use was not different between age groups. Standardized guidelines aimed at facilitating a clientʼs transition toward the safe use of a walking aid are needed. Future research should evaluate if training can mitigate some of the adverse changes to gait stability observed with initial walking aid use.
