Influence of dopaminergic treatment on resting elbow joint angle control mechanisms in patients with Parkinson's disease - a preliminary report.

Acta Bioeng Biomech 2018 ;20(4):75-82

Department of Kinesiology, Faculty of Physiotherapy, University School of Physical Education, Wrocław, Poland.

Purpose: Heightened tonic stretch reflex contributes to increased muscle tone and a more-flexed resting elbow joint angle (EJA) in patients with Parkinson's disease (PD). Dopaminergic medication restores central nervous system (CNS) functioning and decreases resting muscle electrical and mechanical activities. This study aimed to evaluate the effects of dopaminergic medication on parkinsonian rigidity, resting EJA, resting electrical activity (electromyography, EMG) and mechanical properties (myotonometry, MYO) of elbow flexor muscles and the associations of EJA with these muscles resting electrical activity and mechanical properties in PD patients.

A rare case of type 2 entrapment of the median nerve after posterior elbow dislocation with MRI and ultrasound correlation.

Skeletal Radiol 2019 Mar 13. Epub 2019 Mar 13.

Department of Orthopedics, Medical University of South Carolina, Charleston, SC, USA.

A 9-year-old boy sustained an ulnohumeral dislocation with a medial epicondyle fracture and experienced incomplete post-traumatic median nerve palsy in addition to post-traumatic stiffness following closed reduction and cast immobilization. When his motor palsy and stiffness did not improve, MRI and ultrasound were obtained, which demonstrated entrapment of the median nerve in an osseous tunnel at the fracture site, compatible with type 2 median nerve entrapment. Subsequently, the patient underwent surgery to mobilize the medial epicondyle and free the median nerve, resulting in improved range of motion, near complete restoration of motor function, and complete restoration of sensory function in the median nerve distribution within 6 months of surgery.

Sex comparisons of agonist and antagonist muscle electromyographic parameters during two different submaximal isometric fatiguing tasks.

Physiol Rep 2019 Mar;7(5):e14022

Department of Health, Exercise Science, and Recreation Management, The University of Mississippi, University, Mississippi.

To examine the task failure time of the force- and position-based submaximal elbow flexion fatiguing tasks for both sexes, twelve men and eight women visited the laboratory for two separate experimental occasions. During the experiment, they pulled against a rigid restraint for the force task and maintained a constant elbow joint angle to support an equivalent inertial load for the position task. For both fatiguing tasks (50% of the isometric strength at the elbow joint angle of 135 degree), the task failure time, along with the surface electromyographic (EMG) amplitude and mean frequency (MNF) were measured.

Applying LDA-based pattern recognition to predict isometric shoulder and elbow torque generation in individuals with chronic stroke with moderate to severe motor impairment.

J Neuroeng Rehabil 2019 Mar 5;16(1):35. Epub 2019 Mar 5.

Department of Physical Therapy and Human Movement Sciences, Northwestern University, 645 N Michigan Ave, Suite 1100, Chicago, IL, 60611, USA.

Background: Abnormal synergy is a major stroke-related movement impairment that presents as an unintentional contraction of muscles throughout a limb. The flexion synergy, consisting of involuntary flexion coupling of the paretic elbow, wrist, and fingers, is caused by and proportional to the amount of shoulder abduction effort and limits reaching function. A wearable exoskeleton capable of predicting movement intent could augment abduction effort and therefore reduce the negative effects of distal joint flexion synergy. Read More

Skeletal morphology of the early Paleocene plesiadapiform Torrejonia wilsoni (Euarchonta, Palaechthonidae).

J Hum Evol 2019 Mar 11;128:76-92. Epub 2019 Feb 11.

Department of Anthropology, Yale University, P. O. Box 208277, New Haven, CT 06520, USA; Division of Vertebrate Paleontology, Peabody Museum of Natural History, New Haven, CT 06520, USA.

Plesiadapiforms, like other Paleogene mammals, are known mostly from fossil teeth and jaw fragments. The several families of plesiadapiforms known from partial skeletons have all been reconstructed as arborealists, but differences in postcranial morphology among these taxa indicate a diversity of positional behaviors. Here we provide the first detailed descriptions and comparisons of a dentally associated partial skeleton (NMMNH P-54500) and of the most complete dentary with anterior teeth (NMMNH P-71598) pertaining to Torrejonia wilsoni, from the early Paleocene (late Torrejonian To3 interval zone) of the Nacimiento Formation, San Juan Basin, New Mexico, USA.

Negative Patient-Experience Comments After Total Shoulder Arthroplasty.

J Bone Joint Surg Am 2019 Feb;101(4):330-337

Department of Orthopaedic Surgery, New England Baptist Hospital, Tufts University School of Medicine, Boston, Massachusetts.

Background: There is growing interest in enhancing the patient experience after discretionary orthopaedic surgery. Patient narratives are a potentially valuable but largely unscrutinized source of information. Using machine learning to understand sentiment within patient-experience comments, we explored the content of negative comments after total shoulder arthroplasty (TSA), their associated factors, and their relationship with traditional measures of patient satisfaction and with perioperative outcomes.

Integrated System for Monitoring Muscular States during Elbow Flexor Resistance Training in Bedridden Patients.

J Healthc Eng 2019 17;2019:4290957. Epub 2019 Jan 17.

School of Mechanical Engineering, Chongqing University of Technology, No. 69 Hongguang Avenue, Banan District, Chongqing 400054, China.

To improve or maintain the physical function of bedridden patients, appropriate and effective exercises are required during the patient's bed rest. Resistance training (RT) is an effective exercise for improving the physical function of bedridden patients, and the improvement of the physical function is caused by mechanical stimuli associated with RT. Currently, the measured mechanical stimuli are external variables which represent the synthetic effect of multiple muscles and body movements. Read More

The medium-term results of acromioclavicular joint arthroscopy with chondral and meniscal debridement.

J Orthop Surg (Hong Kong) 2019 Jan-Apr;27(1):2309499018817865

Department of Surgery, School of Clinical Science at Monash Health, Monash University, Melbourne Shoulder and Elbow Centre, Brighton, Victoria, Australia.

Purpose:: Surgical management of a young patient with a stable but painful acromioclavicular (AC) joint but normal imagining is a challenging problem. A standard arthroscopic excision of distal clavicle seems too aggressive. An alternative procedure is arthroscopic debridement of the joint, particularly the often torn meniscus, and chondroplasty.
