Elbow Rehab

Winai Chonnaparamutt, Witsarut Supsi
SEFRE (Shoulder-Elbow-Forearm Robotics Economic) rehabilitation system is presented in this paper. SEFRE Rehab System is composed of a robotic manipulator and an exoskeleton, so-called Forearm Supportive Mechanism (FSM). The controller of the system is developed as the Master PC consisting of five modules, that is, Intelligent Control (IC), Patient Communication (PC), Training with Game (TG), Progress Monitoring (PM), and Patient Supervision (PS). These modules support a patient to exercise with SEFRE in six modes, that is, Passive, Passive Stretching, Passive Guiding, Initiating Active, Active Assisted, and Active Resisted...

Modern rehabilitation practices have begun integrating robots, recognizing their significant role in recovery. New and alternative stroke rehabilitation treatments are essential to enhance efficacy and mitigate associated health costs. Today's robotic interventions can play a significant role in advancing rehabilitation. In addition, robots have an inherent ability to perform tasks accurately and reliably and are typically well suited to measure and quantify performance. Most rehabilitation strategies predominantly target activation of the paretic arm...

Children born with the Amyoplasia form of arthrogryposis multiplex congenita (AMC) who lack elbow flexor muscles and have elbow extension contractures usually require assistance in performing ADL's that require reaching their hand to their face, head, and upper body. For tasks involving the UE, the elbow is the key to functional independence. Children born with Amyoplasia may benefit from selective surgeries to enhance functional independence and improve quality of life. Home therapy and splinting following these surgeries is an important part of gaining motion and improving function...

OBJECTIVE: To determine whether there were differences in the cross-sectional area (CSA) and the flattening ratio of the normative ulnar nerve as it passes between the medial epicondyle and the olecranon at 30° of elbow flexion versus 90° of elbow flexion. DESIGN: Bilateral upper extremities of normal healthy adult volunteers were evaluated with ultrasound. The CSA and the flattening ratio of the ulnar nerve at the elbow as it passes between the medial epicondyle and the olecranon were measured, with the elbow flexed at 30° and at 90°, by 2 operators with varying ultrasound scanning experience by using ellipse and direct tracing methods...

This paper features a Spatial Augmented Reality system for rehabilitation of hand and arm movement. The table-top home-based system tracks a subject's hand and creates a virtual audio-visual interface for performing rehabilitation-related tasks that involve wrist, elbow, and shoulder movements. It measures range, speed, and smoothness of movements locally and can send the real-time photos and data to the clinic for further assessment. To evaluate the system, it was tested on two normal subjects and proved functional...

Humeral shaft fracture intramedullary nailing is less invasive than plates and screws. Antegrade technique has postoperative shoulder pain, increased rehab time, and frequent reoperation for rod removal. Published retrograde technique is not collinear with the shaft, has insertion site fractures (5% to 15%), and radial nerve palsies (5%). Our retrograde technique is collinear with the humerus shaft, simpler, and decreases operative fracture risk. The supine patient's elbow is fully flexed. A guide pin is inserted through the triceps tendon to the olecranon fossa roof, aligned with the humerus shaft, and drilled thought the cortex followed by the 6...

After stroke, arm function can be limited by a reduction in the selectivity of movements, due to involuntary coupling of shoulder abduction and elbow flexion, limiting the ability to reach. Gravity compensation of the arm reduces the required active shoulder abduction torques, which results in a larger range of motion instantaneously. Integration of a motivating rehabilitation game in the training program stimulates motor relearning processes during training. During 6 weeks, 8 chronic stroke survivors received 3 sessions of 30 minutes gravity compensated reach training per week using a rehabilitation game, which was evaluated by assessing motor status and a circle drawing task before and after training...

OBJECTIVE: To discuss and evaluate the surgical techniques of arthroscopic rotator cuff repair and its clinical results. METHODS: From March 2002 to May 2005, 44 out of 68 patients treated by arthroscopic rotator cuff repair had been reviewed with a mean post-operation time of 12 months. Of the 44 patients, 40 were available for follow-up, with a mean period of 20.6 (12 - 40) months. The mean age was 56 (30 - 81) years. According to Gerber classification, there were 8 partial tears, 27 small tears and 5 massive tears...

The AdVAntage Arm is an above-elbow (AE) body-powered arm designed to improve upon, and overcome, some of the major limitations of conventional prostheses. It is the result of research and development (R&D) accomplished at the Center for Engineering Design (CED), University of Utah and Sarcos Research Corporation (SRC), Salt Lake City, UT. The AdVAntage Arm was developed to provide the following main features: lightweight, independent elbow and terminal device (TD) control, and a cable recovery system for full TD actuation at any elbow position...

The Modular Electromechanical Lock Actuator (MELA) is the result of research and development (R&D) conducted under the direction of Dudley S. Childress, PhD, at the Northwestern University Prosthetics Research Laboratory (NUPRL), Chicago, Illinois. NUPRL, based upon experience with prostheses for persons with high-level, above-elbow amputations, developed the MELA to assist those persons with amputation who experience difficulty in operating existing manual elbows, whether with a conventional harness, nudge control, excursion amplifier, or other arrangement...
