These experiments were designed to investigate illusions of movements of the fingers produced by combined feedback from muscle spindle receptors and receptors located in different regions of the skin of the hand. Vibration (100 Hz) applied in cyclic bursts (4 s 'on', 4 s 'off') over the tendons of the finger extensors of the right wrist produced illusions of flexion-extension of the fingers. Cu...

Background: Pain in metacarpophalangeal (MCP)-joints patients presenting with clinically suspect arthralgia (CSA) is one of the clinical features by which are considered at risk for progression to inflammatory arthritis (IA). As such this symptom characteristic CSA and therefore part a list parameters determined an EULAR-taskforce identify more homogeneous group within (the EULAR definition sus...

OBJECTIVES To test the reliability of new ultrasound (US) definitions and quantification of synovial hypertrophy (SH) and power Doppler (PD) signal, separately and in combination, in a range of joints in patients with rheumatoid arthritis (RA) using the European League Against Rheumatisms-Outcomes Measures in Rheumatology (EULAR-OMERACT) combined score for PD and SH. METHODS A stepwise approa...

INTRODUCTION Ultrasonography (US) might have an added value to clinical examination in diagnosing early rheumatoid arthritis (RA) and assessing remission of RA. We aimed to clarify the added value of US in RA in these situations performing a systematic review. METHODS A systematic literature search was performed for RA, US, diagnosis and remission. Methodological quality was assessed; the wid...

The metacarpophalangeal (MCP) joints bestow important strength to the longitudinal and transverse arch systems of the hand. In addition, these joints guide active movements of the fingers in 2 degrees of freedom, while allowing sufficient laxity for passive accessory motions. Both stability and mobility functions are attained in the healthy hand by a complex interaction among the muscles and th...

BACKGROUND In rheumatoid arthritis (RA), hand synovitis appears especially in wrist, metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints. In hand osteoarthritis (OA), potential inflammatory changes are mainly present in PIP and distal interphalangeal (DIP) joints. Joint inflammation can be visualised by fluorescence optical imaging (FOI) and musculoskeletal ultrasound (US). OB...

OBJECTIVE Rheumatoid arthritis (RA) often results in deformities at the metacarpophalangeal (MCP) joints. Patients with severe deformities can be treated by silicone metacarpophalangeal joint arthroplasty (SMPA). The objective of the study is to prospectively compare long-term outcomes for an SMPA surgical and a nonsurgical cohort of RA patients. METHODS A total of 67 surgical and 95 nonsurgi...

Abstract The purpose of this study was to measure the tension in the flexor digitorum profundus (FDP) tendon in zone II and the digit angle during joint manipulations that replicate rehabilitation protocols. Eight FDP tendons from eight human cadavers were used in this study. The dynamic tension in zone II of the tendon and metacarpophalangeal (MCP) joint angle were measured in various wrist an...

There is rare studies with regard to sesamoid bone variations of the hand in addition to its prevalence and distribution. This study aims to assess both the prevalence and variation of sesamoid bones of the hand. A retrospective review of posteroanterior (PA) and oblique radiographs of 436 left and 414 right hands of 850 adult patients obtained from four hospitals was performed. All X-ray films...
