Asymmetry and Variability Should Be Included in the Assessment of Gait Function in Poststroke Hemiplegia With Independent Ambulation During Early Rehabilitation.

Objective: To extract independent features from spatiotemporal data of poststroke gait.

Design: Retrospective observational study.

Setting: Motion analysis laboratory in the rehabilitation department of a university hospital.

Change in Center of Pressure Progression in the Foot Provides Clues for Functional Improvement of the More Affected Lower Limb During Post-stroke Gait Rehabilitation.

Objective: The aim of this study was to determine the clinical significance of the anterior-posterior displacement of the center of pressure in the foot (apCoP) in post-stroke gait rehabilitation.

Design: This observational study was conducted in a tertiary hospital. Forty-two subacute post-stroke patients were included.

Sonoanatomy of the deep branch of the ulnar nerve.

Introduction: This study evaluated the sonoanatomy of the deep motor branch of the ulnar nerve (DBUN) using high-resolution ultrasonography (HRUS).

Methods: In 60 wrists of 30 healthy adults, the gross course, cross-sectional area (CSA), and diameter of the DBUN were observed by HRUS (frequency band 3-16 MHz). Its course was assessed by using the distance from anatomical landmarks and depth from the skin.

Pilot study: Differences in echo intensity ratios between ulnar and median innervated muscles in ulnar neuropathy.

Background: This study evaluated muscle echo intensity (EI) ratio in patients with ulnar neuropathy at the elbow (UNE) and healthy controls.

Methods: In this prospective study, 28 patients with electrodiagnostically confirmed unilateral UNE and 12 healthy controls were ultrasonographically assessed for EI ratios of the hypothenar and thenar muscles. The affected and unaffected hands between the UNE patients and controls and patient subgroups (subdivided according to electrodiagnostic severity) were compared to determine any significant differences.

Could Ultrasound-Guided Stimulation of Sural Nerve Affect Nerve Conduction Study?

Objective: To determine anatomical variation of the sural nerve (SN) by ultrasonography (US) and compare sensory nerve action potential (SNAP) of the SN obtained by a control method to that obtained with adjusted method using US.

Methods: Eighty legs of 40 healthy volunteers were enrolled. The location and formation of SN were investigated through US.

Anterior-posterior displacement of center of pressure measured by insole foot pressure measurement system in subacute recovery stage of post-stroke hemiplegia.

Background: Anterior-posterior displacement of center of pressure (AP_CoP) reflects stance limb function. However, AP_CoP's clinical applicability in post-stroke hemiplegia is unclear.

Objective: To investigate the clinical usefulness of parameters from AP_CoP in subacute stage post-stroke hemiplegia, their relationships with usage of gait aid, functional ambulatory category, and spatial-temporal parameters were tested.

Carpal Tunnel Syndrome Assessment With Ultrasonography: A Comparison Between Non-diabetic and Diabetic Patients.

Objective: To investigate the diagnostic value of cross-sectional area (CSA) and wrist to forearm ratio (WFR) in patients with electro-diagnosed carpal tunnel syndrome (CTS) with or without diabetes mellitus (DM).

Methods: We retrospectively studied 256 CTS wrists and 77 healthy wrists in a single center between January 1, 2008 and January 1, 2013. The CSA and WFR were calculated for each wrist.
