background: carpal tunnel syndrome (cts) is one of the most common musculoskeletal disorders among computer users. computer users exhibit various wrist angles while typing. dynamic changes of wrist angle may cause different degrees of median nerve compression. the objective of this study was thus to investigate the effects of the combination of wrist flexion-extension with wrist deviation on me...

PURPOSE Assessment of wrist motion is important in diagnosing and treating motion impairment after injuries to the wrist. Little is known of how finger posture influences the movement of the wrist. The aim of this study was to investigate the effect of finger constraints on the maximum circumduction movement of the wrist. METHODS Fifteen male right-handed subjects performed maximal circumfere...

We investigate whether applying an internal radiocarpal-spanning plate with the wrist in slight extension affects the biomechanical stability of the construct. An unstable distal radius fracture was simulated in 10 cadaveric specimens and immobilized with a radiocarpal-spanning plate holding the wrist in a neutral position. This construct was then physiologically loaded through the wrist flexor...

Kettlebell exercises are more efficient for an athlete to increase his or her muscle strength. However it carries the risk of injury especially in the beginners. A 39 year old gentleman came to our clinic with radial sided wrist pain following kettlebell exercises. Clinically patient had swelling and tenderness over the tendons in the first dorsal wrist compartment, besides Finklesten test was ...

A Filipino female teenager with gross deformity of her right wrist, came as an outpatient for radiographic evaluation nonspecific pain and numbness after prolonged repetitive, active wrist movements like writing clapping, are noted no history trauma, infection, or surgical intervention the aforementioned wrist.

Wrist splints are commonly prescribed to limit wrist motion and provide support at night and during inactive periods but are often used in the workplace. In theory, splinting the wrist should reduce wrist extensor muscle activity by stabilizing the joint and reducing the need for co-contraction to maintain posture. Ten healthy volunteers underwent a series of 24 10-s gripping trials with surfac...

BACKGROUND Management of the end-stage rheumatoid wrist is controversial. The most common treatment is total wrist fusion. Total wrist arthroplasty offers a motion-preserving alternative. Comparison of outcomes for total wrist arthroplasty and total wrist fusion is necessary for evidence-based decision making. The purpose of this systematic review was to scientifically evaluate the existing lit...

Fingertip forces result from the activation of muscles that cross the wrist and muscles whose origins and insertions reside within the hand (extrinsic and intrinsic hand muscles, respectively). Thus, tasks that involve changes in wrist angle affect the moment arm and length, hence the force-producing capabilities, of extrinsic muscles only. If a grasping task requires the exertion of constant f...

Children with brachial plexus birth injuries often require tendon transfer to restore active wrist extension and maximize hand function. The purpose of this study is to assess the clinical results in children with brachial plexus birth injuries after tendon transfer to reconstruct active wrist extension. Over a 10-year period, 21 children (11 male, 10 female) underwent tendon transfer to recons...

The purpose of this study was to quantify the response of the forearm musculature to combinations of wrist and forearm posture and grip force. Ten healthy individuals performed five relative handgrip efforts (5%, 50%, 70% and 100% of maximum, and 50 N) for combinations of three wrist postures (flexed, neutral and extended) and three forearm postures (pronated, neutral and supinated). 'Baseline'...
