Development and Experimental Evaluation of a Novel Portable Haptic Robotic Exoskeleton Glove System for Patients with Brachial Plexus Injuries.

This paper presents the development and experimental evaluation of a portable haptic exoskeleton glove system designed for people who suffer from brachial plexus injuries to restore their lost grasping functionality. The proposed glove system involves force perception, linkage-driven finger mechanism, and personalized voice control to achieve various grasping functionality requirements. The fully integrated system provides our wearable device with lightweight, portable, and comfortable characterization for grasping objects used in daily activities.

Design, Control, and Experimental Evaluation of A Novel Robotic Glove System for Patients with Brachial Plexus Injuries.

This paper presents the development of an exoskeleton glove system for people who suffer from brachial plexus injuries, aiming to assist their lost grasping functionality. The robotic system consists of a portable glove system and an embedded controller. The glove system consists of Linear Series Elastic Actuators (LSEA), Rotary Series Elastic Actuators (RSEA), and optimized finger linkages to provide imitated human motion to each finger and a coupled motion of the hand.

Rare Occurrence of Extradigital Glomangioma in the Prepatellar Bursa of a 40-Year-Old: A Case Study.

Introduction: A solitary subcutaneous mass can be a common clinical finding for patients symptomatic for knee pain, especially when direct pressure by kneeling on the anterior aspect of the knee causes pain.

Case Report: We present a 40-year-old who noticed a small fluid filled mass that has become progressively larger and more painful over the past 7 years. The patient's primary complaint was sharp pain with direct contact.

The Role of Dual-Mobility Components in Total Hip Arthroplasty.

➤: Dual mobility (DM) refers to a now widely available option for total hip articulation. DM implants feature a small inner head, a hard bearing, that connects via a taper fit onto the femoral trunnion. This head freely rotates but is encased inside a larger, outer polyethylene head that articulates with a smooth acetabular component.

Data Driven Calibration and Control of Compact Lightweight Series Elastic Actuators for Robotic Exoskeleton Gloves.

The working principle of a SEA is based on using an elastic material connected serially to the mechanical power source to simulate the dynamic behavior of a human muscle. Due to weight and size limitations of a wearable robotic exoskeleton, the hardware design of the SEA is limited. Compact and lightweight SEAs usually have noisy signal output, and can easily be deformed.

Personalized Voice Activated Grasping System for a Robotic Exoskeleton Glove .

This paper proposes a novel human machine interface (HMI) and electronics system design to control a rehabilitation robotic exoskeleton glove. Such system can be activated with biometric authentication using the user's voice, take voice commands as input, recognize the command and perform biometric authentication in real-time with limited computing power, and execute the command on the exoskeleton. The electronics design is a stand-alone plug-and-play modulated design independent of the exoskeleton design.

Two-stage Treatment for Hip and Knee Periprosthetic Infections.

Two-stage exchange remains the standard of care for treatment of chronic periprosthetic infections in the United States. The strategy involves three steps; a resection arthroplasty with a thorough debridement and placement of a temporary spacer, an extended period of targeted antibiotics, and finally, a second definitive reconstruction procedure. The lengthy period of time between surgeries, where patients have diminished mobility, a long period of IV antibiotics and its considerable side effects, and the need for two large operations and hospitalizations places physiologic and emotional demands on patients and their families.

Dislocation rates following total hip arthroplasty via the direct anterior approach in a consecutive, non-selective cohort.

Aims: Use of the direct anterior approach (DAA) for total hip arthroplasty (THA) has increased in recent years due to proposed benefits, including a lower risk of dislocation and improved early functional recovery. This study investigates the dislocation rate in a non-selective, consecutive cohort undergoing THA via the DAA without any exclusion or bias in patient selection based on habitus, deformity, age, sex, or fixation method.

Methods: We retrospectively reviewed all patients undergoing THA via the DAA between 2011 and 2017 at our institution.

A NOVEL DESIGN OF A ROBOTIC GLOVE SYSTEM FOR PATIENTS WITH BRACHIAL PLEXUS INJURIES.

This paper presents the design of an exoskeleton glove system for people who suffer from the brachial plexus injuries in an effort to restore their lost grasping functionality. The robotic system consists of an embedded controller and a portable glove system. The glove system consists of Linear Series Elastic Actuators (SEA), Rotary SEA and optimized finger linkages to provide motion to each finger and a coupled motion of the hand and the wrist.

INTEGRATED AND CONFIGURABLE VOICE ACTIVATION AND SPEAKER VERIFICATION SYSTEM FOR A ROBOTIC EXOSKELETON GLOVE.

Efficient human-machine interface (HMI) for exoskeletons remains an active research topic, where sample methods have been proposed including using computer vision, EEG (electroencephalogram), and voice recognition. However, some of these methods lack sufficient accuracy, security, and portability. This paper proposes a HMI referred as integrated trigger-word configurable voice activation and speaker verification system (CVASV).

An Innovative Method for Plantar Plate Repair: Technique Guide and Case Report.

Disruption of the plantar plate is a common cause of forefoot pain, metatarsalgia, and metatarsophalangeal joint malalignment. Although surgical repair of the plantar plate has improved, there has been no consensus on the clinical superiority of any single technique, or combination of techniques, described in the literature to date. In this publication, we report a case of plantar plate injury treated with an innovative new technique with 20-month follow-up.
