Ultrasound guidance is valuable for performing precise joint interventions. Joint interventions may be requested for therapeutic and diagnostic pain injections, joint aspiration in the setting of suspected infection, or contrast injection for arthrography. In practice, interventions of the shoulder girdle, elbow, and hand/wrist joints may be performed without any imaging guidance. Read More

Avascular necrosis of the proximal pole of the capitate is an exceedingly rare pathology with few therapeutic solutions. The largest published series concerned a cohort of 6 cases over 10 years. The present case concerns our experience with avascular necrosis of the capitate in a 20-year-old woman. Read More

In the macaque, the posterior parietal area V6A is involved in the control of all phases of reach-to-grasp actions: the transport phase, given that reaching neurons are sensitive to the direction and amplitude of arm movement, and the grasping phase, since reaching neurons are also sensitive to wrist orientation and hand shaping. Reaching and grasping activity are corollary discharges which, together with the somatosensory and visual signals related to the same movement, allow V6A to act as a state estimator that signals discrepancies during the motor act in order to maintain consistency between the ongoing movement and the desired one. Area V6A is also able to encode the target of an action because of gaze-dependent visual neurons and real-position cells. Read More

Background: The global inclination of stroke onset in earlier years of life and increased lifespan have resulted in an increased chronic post-stroke-related disability. The precise and simplistic approach such as the correlation of Fugl-Meyer Assessment (FMA) with Transcranial Magnetic Stimulation (TMS) parameters, Resting Motor Threshold (RMT) and Motor Evoked Potential (MEP), in patients with stroke might play a critical role, given the prognostic value of MEP, a measure of cortical excitability, and might be the key point in prescribing appropriate therapeutic strategies.

Objective: The study aimed to determine the correlation of FMA-based impairment in the upper extremity function specifically of the wrist and hand with respect to the neurophysiological parameters of corticospinal tract integrity. Read More

Purpose: Following surgical repair of distal radius fractures, range of movement (ROM) exercises are the primary approach for restoring movement during early rehabilitation. Specified purposeful activities can also be used, but the movement produced by activities is not well-understood. The study aimed to evaluate and compare movement during purposeful activity and ROM exercises METHODS: Thirty-five adults with a surgically repaired distal radius facture undertook two 10-minutes interventions: purposeful activity (PA) and active ROM exercises (AE), separated by a 60 minute washout, in random order.
