INTRODUCTION: Orthopedic walking boots have been widely used in place of traditional fiberglass casts for a variety of orthopedic injuries and post-surgical interventions. These walking boots create a leg length discrepancy (LLD). LLD has been shown to alter the kinematics and kinetics of gait and are associated with lumbar and lower limb conditions such as: foot over pronation, low back pain, scoliosis, and osteoarthritis of the hip and knee joints. Past gait analyses research with orthopedic boots is limited to findings on the ipsilateral limb...

OBJECTIVE: Readmission rates are known to be high for vascular surgery patients in general, but there are limited data describing the risk of surgical and nonsurgical readmission among patients with diabetic foot ulcers (DFUs). Our aim was to identify factors associated with unplanned readmission in DFU patients treated in a multidisciplinary setting. METHODS: We studied a single-center cohort of patients enrolled in a multidisciplinary diabetic foot service (July 2012-June 2017)...

The Kinect v2 sensor may be a cheap and easy to use sensor to quantify gait in clinical settings, especially when applied in set-ups integrating multiple Kinect sensors to increase the measurement volume. Reliable estimates of foot placement locations are required to quantify spatial gait parameters. This study aimed to systematically evaluate the effects of distance from the sensor, side and step length on estimates of foot placement locations based on Kinect's ankle body points. Subjects (n = 12) performed stepping trials at imposed foot placement locations distanced 2 m or 3 m from the Kinect sensor (distance), for left and right foot placement locations (side), and for five imposed step lengths...

Increased variability of spatio-temporal features while walking is related to increased risk of falls. It is thought that variability in foot placement and timing reflects responses to mechanical instability while walking. The purpose of this study was to determine whether 'extreme' values of step length, width and time follow transient periods of low mechanical stability during the single support phase of gait in healthy young adults. We conducted secondary analysis of a portion of an existing dataset. Eleven healthy adults walked on an instrumented treadmill...

BACKGROUND: Foot ulcers in diabetic patients often require free flaps. A long vascular pedicle is mandatory so that more proximal vessels can be used as recipient vessels, especially when the flap is used to reconstruct distal foot defects. We evaluated the outcome of diabetic foot defect that were reconstructed using thoracodorsal artery perforator (TDAP) flaps with long vascular pedicles. PATIENTS AND METHODS: We reconstructed the foot defects of 22 diabetic patients...

BACKGROUND: Stoma formation in colorectal surgery is a recognized independent cause of prolonged hospital stay. It has been shown that preoperative stoma education and siting leads to a reduction in the length of hospital stay. Despite this, the length of time to independent stoma management and the variables that affect this has not been well studied. We conducted a prospective case series to analyse this. METHODS: A total of 107 consecutive colorectal surgery patients undergoing stoma formation at two separate large metropolitan hospitals, one private funded and the other government funded, were enrolled in a prospective case series...

BACKGROUND: An association between hallux rigidus and metatarsus primus elevatus (MPE) has been suggested, although there remains no general consensus about the nature of this relationship. Past studies were limited due to inaccuracies of assessing MPE on 2-dimensional radiographs. The aims of this study were to (1) assess and compare foot alignment in patients with and without hallux rigidus using 3-dimensional (3D) reconstructions from weightbearing computed tomography (CT) and (2) assess intraobserver and interobserver reliability of these measurements...

PURPOSE: It is well known that total knee replacement surgery decreases pain and improves function, but the effect on postural assessment needs to be studied better with the use of new technological devices. Total knee arthroplasty (TKA) improves motor coordination and stability of the knee. On the other hand, changing joint functionality can modify the balance. The aim of this trial is to record and analyze the static and dynamic baropodometric data of patients in the first few months following joint replacement...

Pulse waveform analyses have become established components of cardiovascular research. Recently several methods have been proposed as tools to measure aortic pulse wave velocity (aPWV). The carotid-femoral pulse wave velocity (cf-PWV), the current clinical gold standard method for the noninvasive assessment of aPWV, uses the carotid - to - femoral pulse transit time (cf-PTT) and an estimated path length to derive cf-PWV. The heart-ankle PWV (ha-PWV), brachial-ankle PWV (ba-PWV) and finger-toe (ft-PWV) are also methods presuming to approximate aPWV based on time delays between physiological cardiovascular signals at two locations (~ heart-ankle PTT, ha-PTT; ~ brachial-ankle PTT, ba-PTT; ~ finger-toe PTT, ft-PTT) and a path length typically derived from the subject's height...

Females, as compared with males, have a higher proportion of injuries in the foot region. However, the reason for this gender difference regarding foot injuries remains unclear. This study aimed to investigate gender differences associated with rearfoot, midfoot, and forefoot kinematics during running. Twelve healthy males and 12 females ran on a treadmill. The running speed was set to speed which changes from walking to running. Three-dimensional kinematics of rearfoot, midfoot, and forefoot were collected and compared between males and females...

REVIEW
D Scott Nickerson
External neurolysis of the nerve at fibro-osseous tunnels has been proprosed to treat or prevent signs, symptoms, and complications in the lower extremity of diabetes patients with sensorimotor polyneuropathy. Nerve decompression is justified in the presence of symptomatic compressed nerves in the several fibro-osseous tunnels of the extremities, which are known to be frequent in diabetes. Quite a body of literature has accumulated reporting results after such nerve decompression in the leg, describing pain relief and sensibility improvement, as well as balance recovery, diabetic foot ulcer prevention, curtailed ulcer recurrence risk, and amputation avoidance...
