Article Abstract
Injury conditions affecting the upper extremity may lead to severe functional impairment and an accurate evaluation is needed in order to select the most effective treatment in a rehabilitation program. This study focused on simultaneous electromyographic and kinematic analysis to assess movement patterns of upper extremity during a basic daily activity, considering different demands existing within the task. Twenty-five healthy subjects, average age 19.8 ys SD 1.7 ys, with no upper extremity impairment, were assessed by means of electromyography (EMG) and a 3D motion capture system while performing a task that required reach, transport and release. Integrated EMG (iEMG), timing of muscle onset and active range of motion (AROM) were calculated for each subject. Data were compared within each phase and between the three phases and a repeated measure ANOVA was used for statistical analysis. We found early activation of upper trapezius associated with high activity of serratus anterior for proximal stability while anterior deltoid and triceps brachii performed shoulder flexion and elbow extension, in Reach phase. In Transport phase there was early and higher activation of upper trapezius, higher muscle activity of almost all muscles and increased AROM of all joints. No change in flexion/extension wrist posture with increased forearm muscles activity were identified as the main control strategy to keep optimal grasping. Triceps brachii was found to act as an important synergist in shoulder abduction and extension in free load conditions. Such information can lead clinicians to more specific assessment and subsequent better intervention in upper extremity rehabilitation.
A rare type of localized gigantism known as macrodystrophia lipomatosa is characterized by a disproportionate increase in fibroadipose tissues and a gradual overgrowth of all mesenchymal elements. The distribution in the lower extremities' plantar nerves and the upper extremity's median nerve is most commonly observed. This abnormality is congenital and typically manifests at birth or during the neonatal stage.
Subcutaneous emphysema, caused by the presence of air or gas in subcutaneous tissues, can be infectious or noninfectious. A thorough clinical evaluation, including both physical examination and radiological imaging, is required to distinguish benign subcutaneous emphysema from necrotizing soft tissue infections. In this article, we report a 12-year-old female patient with benign subcutaneous emphysema of the upper extremity and highlight the importance of an accurate diagnosis to avoid unnecessary surgical intervention.
Objectives: In this study, we aimed to evaluate microvascular changes using nailfold capillaroscopy in patients who underwent digit replantation and revascularization.
Patients And Methods: A total of 46 patients (34 males, 12 females; mean age: 45.8±17.
Background: Congenital radioulnar synostosis (CRUS) is a rare upper limb deformity characterized by impaired rotational movement of the forearm. Rotational osteotomy is a commonly employed surgical procedure for treatment. This study aimed to analyze its surgical efficacy in treating CRUS in children.
Purpose: Bookmarking is a qualitative method used to assign descriptive labels to ranges of patient-reported outcome (PROM) scores. We aimed to evaluate variability between bookmarking samples and test score ranges where there was variability in expert opinion in previous studies.
Methods: We conducted two bookmarking sessions with patients who experienced orthopaedic fractures (n = 11) and one session with orthopaedic clinicians (n = 10).
