Postoperative healing patterns in Elbow using electromyography: Towards the development of a wearable mechatronic Elbow Brace
2017 International Conference on Rehabilitation Robotics (ICORR), 2017Co-Authors: Raneem Haddara, Yue Zhou, Shrikant Chinchalkar, Ana Luisa TrejosAbstract:Musculoskeletal (MSK) conditions are the most common cause of severe long-term pain and physical disability. Current postoperative treatment for patients requires them to follow a long-term physiotherapy program customized for each specific case; however, this process can be complex, time-consuming and without the right therapy it may end up being ineffective. A possible solution involves the development of wearable mechatronic Elbow Braces that use electromyography (EMG) to identify patient intent. However, EMG characteristics change based on the health of the individual and therefore require further investigation. In order to quantify the progress of MSK injury patients and assess their neuromuscular health, EMG signals from 16 healthy individuals and 15 postoperative patients were collected and analyzed. The experiments conducted show that EMG can be used as a method for assessing MSK health. A normal range across the muscle groups has been identified to which the patient population was compared. This showed statistically significant differences in the magnitudes of muscle recruitment and activation between the two groups. Furthermore, a comparison within the patient population at the beginning of their therapy versus at the end of their therapy was conducted. Statistical differences arose in this second analysis further proving that patients' signals tend to change and show trends closer to those of the healthy population.

development of an emg driven control system for a wearable mechatronic Elbow Brace
IEEE-EMBS International Conference on Biomedical and Health Informatics, 2016Co-Authors: Tyler Desplenter, A Kyrylova, Ana Luisa TrejosAbstract:The focus of this research is the implementation of a control system which actuates a wearable mechatronics-enabled Elbow Brace (ME-Brace) through Elbow motion tracking tasks using estimates derived from an EMG-driven mapping model. The accuracy and repeatability of the control system during a tracking task, using data collected from healthy subjects, has been quantified to support improvement of future devices and control systems. The mean accuracy, represented by the root mean square error in position between the subject and Brace, and the repeatability, represented by the mean standard deviation between Brace trials, was found to be 1.22 ± 0.28° and 0.10°, respectively. As no targets exist in the literature for these quantities, this research provides a baseline measurement of the accuracy and repeatability of controlling a wearable mechatronic Elbow Brace during an Elbow tracking task.

The Kudo total Elbow arthroplasty in patients with rheumatoid arthritis
Journal of shoulder and elbow surgery, 2004Co-Authors: Karel Willems, Luc De SmetAbstract:A Kudo total Elbow arthroplasty (TEA) was performed in 36 Elbows in 35 patients with rheumatoid arthritis. Of those 35, 4 died, 6 prostheses were revised, and 2 were lost to follow-up. Twenty-four Elbows with a mean follow-up of 58 months were radiologically and clinically reviewed. Sixteen were scored as excellent by use of the Mayo score and Hospital for Special Surgery 2 score. The mean increase in active motion was 25°. Two humeral and four ulnar radiologic loosenings were noted. Two early dislocations were successfully treated with closed reduction and cast immobilization, two patients used an Elbow Brace after the closed reduction, and one patient underwent a resection arthroplasty for instability and deep wound infection. Four aseptic loosenings, of which three had an intraoperative fracture at the index operation and one had instability, were revised. Despite initially excellent results, longer follow-up of TEA in rheumatoid patients demonstrated deterioration of the outcome and increased loosening.

Combined Clinic-Home Approach for Upper Limb Robotic Therapy After Stroke: A Pilot Study.
Archives of physical medicine and rehabilitation, 2015Co-Authors: Grace Kim, Lisa Rivera, Joel SteinAbstract:Abstract Objective To investigate the feasibility of a combined clinic-home intervention using a robotic Elbow Brace and, secondarily, to collect preliminary data on the efficacy of this clinic-home intervention. Design Nonrandomized pre-/postinterventional study. Setting Outpatient clinic and participants' homes. Participants Individuals at least 6 months after stroke (N=11; 5 women and 6 men; mean age, 51.7y; mean time since stroke, 7.6y; mean Fugl-Meyer Assessment of the Upper Extremity [FMA-UE] score, 22 of 66) were enrolled from the community. Interventions Participants received training in an outpatient clinic from an experienced occupational therapist to gain independence with use of the device (3–9 sessions) followed by a 6-week home program using the device at home. Main Outcome Measures Five instruments were administered before and after the study intervention: Modified Ashworth Scale, Box and Blocks test, FMA-UE, Arm Motor Ability Test, and Motor Activity Log-Amount of Use and Motor Activity Log-How Well subscales (MAL-AOU, MAL-HW). Results Nine participants completed the study. Participants used the device on average 42.9min/d, 5.3d/wk. The FMA-UE ( t =3.32; P =.01), MAL-AOU ( t =4.40; P =.002), and MAL-HW ( t =4.02; P =.004) scores showed statistically significant improvement from baseline to discharge; the MAL-AOU ( t =2.61; P =.035) and MAL-HW ( t =2.47; P =.043) scores were also significantly improved from baseline to 3-month follow-up. Conclusions This combined clinic-home intervention was feasible and effective. Participants demonstrated improvements in arm impairment and self-reported use of the arm from baseline to discharge; they continued to report significant improvement in actual use of the arm at 3-month follow-up.

Elbow Brace and Rehabilitation
Surgical Techniques for Trauma and Sports Related Injuries of the Elbow, 2019Co-Authors: Alessandro Marinelli, Enrico Guerra, Alice Ritali, Roberto RotiniAbstract:Braces can be effective devices in different phases of Elbow rehabilitation, and their use, especially if integrated with other modes of physical therapies, can improve the recovery in many Elbow disorders. Elbow Braces are generally preferred over casts, because they are more comfortable for the patients and more practical for the caregivers. On the basis of their function, we can identify two different types of Braces: the protection Braces are devices which prevent excessive stress on the articular surface, capsule, ligaments, or tendons; they are used after trauma and reconstructive surgeries or in cases of inflammatory or degenerative situations. Mobilization Braces, used to treat Elbow stiffness, are mechanical devices exerting forces to stretch the retracted tissue stimulating the recovery of the Elbow movement. A shared Brace nomenclature can simplify the communication between the different professional figures involved. The authors present Brace indications and protocols in Elbow rehabilitation. In the future, 3D printing technology will permit to create personalized casts and Braces that will be lighter, less bulky, and water friendly, making more comfortable their long-term wear.

Humeral fracture between a total Elbow and total shoulder arthroplasty.
Orthopedics, 2011Co-Authors: Andreas F. Mavrogenis, Enrico Guerra, Andrea Angelini, Roberto RotiniAbstract:This article presents a case of a 71-year-old woman with a humeral fracture between a cementless reverse total shoulder arthroplasty and a cemented total Elbow arthroplasty and discusses our treatment plan. Surgical treatment was performed after the patient was informed of possible complications and the benefits of surgery including: early, complete restoration of arm anatomy, greater functional improvement of the adjacent joints, and increased risk of nonunion with nonoperative treatment.The fracture was comminuted and extended proximally around the shoulder prosthesis. Through the posterior approach, the radial nerve was identified and protected. Both prostheses were found firmly fixed to bone. The fracture around the shoulder prosthesis was reduced first using a strut allograft and reduction clamps. Next, arm alignment restoration and distal humerus reduction were performed. The construct was neutralized with a 3.5-mm locking plate spanning the whole length of the humerus. The locking plate was positioned posterolaterally and the strut medially in a 90° to 90° configuration secured with wires and cables.A hinged Elbow Brace was applied for 6 weeks postoperatively. Active range of motion exercises of the wrist and hand and passive motion of the Elbow and shoulder were started at 4 to 5 days postoperatively. At 2 weeks postoperatively, passive motion of the Elbow and shoulder progressed to strengthening exercises. Thereafter, the patient underwent several weeks of physical therapy to restore motion, strength, and function of the upper extremity with instructions not to overload the arm and avoid heavy work and sports for as long as 1 year. At 10 months postoperatively, radiographs of the arm showed a stable construct; the patient had resumed full activities of daily living.

Elbow Brace in Physical Therapy
Treatment of Elbow Lesions, 1Co-Authors: Roberto Rotini, Alessandro MarinelliAbstract:The Elbow is a joint that, following trauma, very easily becomes stiff. In an attempt to limit the occurrence of such a complication, an articulated Brace should be used in the rehabilitation phase to enable earlier movement that was impossible to obtain with the splints or casts commonly used years ago.
