Assessing Functional Mobility After Lower Limb Reconstruction

Abstract

The HMS shows satisfactory reliability and validity and may provide a platform to support adaptable, personalized rehabilitation and enhanced service evaluation to facilitate optimal patient outcomes.

Enhanced recovery after surgery: Current research insights and future direction

“…Studies in the early post-operative period have offered insight on patient mobility and functional recovery[ 59 ]. Cook et al[ 60 ] monitored patient steps after elective cardiac surgery.…”

Gait Analysis From a Single Ear-Worn Sensor: Reliability and Clinical Evaluation for Orthopaedic Patients

“…In general, a decrease in right stride time (increase in speed of walking), step time asymmetry and amplitude asymmetry are important clinical features for observing recovery of the patients. [23,24] Kwasnicki et al [5] single -3D accelerometer worn on the ear (e-AR) -healthy subjects [12,22,23,24] -patients after hip or knee replacement surgery and patients with knee Osteoarthritis (OA) [24] -patients following lower limb trauma reconstruction [5] -treadmill walking [12,23,24] -walking in a corridor [5,22] -detection of gait asymmetry [22,24] -psychometric evaluation of a sensor-based mobility score called HMS [5] Bamberg et al [8] multiple -two dual axis accelerometer -three gyroscopes placed at the back of shoes -healthy subjects -PD patients -walking at self-selected natural Pace expressed "free gait" outside laboratory validation of GaitShoe system using healthy and PD patients Selles et al [13] multiple -two uniaxial accelerometers on the shank -healthy subjects -unilateral transtibial amputees -walking on straight track with a Kistler force platform validation of gait parameters using controls and transtibial amputees Turcot et al [14] multiple -two triaxial accelerometer -two triaxial gyroscope -asymptomatic subjects -patients with knee OA -walking on straight track with a Kistler force platform discrimination between asymptomatic subjects and medial knee OA patients Yoneyama et al [20,21] Sejdic et al [16] single -trunk mounted accelerometer -healthy subjects -PD patients [20,21] -PD and peripheral neuropathy patients [16] -walking on level ground [20,21] -treadmill walking [16] -accelerometry-based evaluation and assessment of daily gait characteristics [20,21] -comparison of accelerometer features between healthy subjects and patients groups [16]...…”

“…These data was acquired for one of our previous studies already published in [5] for the purpose of psychometric evaluation of a sensorbased mobility score. Based on the protocol the patients performed a 6-Minute walk along the corridor, Timed Up & Go and Timed Up & down stairs.…”

“…These are listed in Table I ( [5], [8], [12]- [14], [16], [20]- [25]). For example, the ear-worn Activity Recognition (e-AR) sensor has been used in both experimental and clinical settings [5], [12], [22]- [25]. The sensor includes an accelerometer and the major advantage of the sensor is in its bio-inspired design and ease of consistence sensor placement.…”

“…Quantitative gait analysis is now an integral part of common surgical workflows including joint arthroplasty, correction osteotomies and surgeries for children with Cerebral Palsy (CP) [3] [4]. It has been used for evaluating recovery of patients following major lower limb trauma [5] and reducing the risk of injuries [6]. Advances in sensing technologies have also enabled the development of miniaturised sensors, either wearable or positioned in the ambient environment, for providing real-time information that can be wirelessly interrogated [7]- [15].…”
