A Prospective, Multicenter, Randomized, Evaluator-Blinded, Split-Hand Study to Evaluate the Effectiveness and Safety of Large-Gel-Particle Hyaluronic Acid with Lidocaine for the Correction of Volume Deficits in the Dorsal Hand.

ABSTRACT: BACKGROUND:Hand rejuvenation has become increasingly popular, but there are few reports published on the use of hyaluronic acid gels for correction of volume deficits in the dorsal hand. METHODS:This study evaluated the efficacy and safety of large-gel-particle hyaluronic acid with lidocaine, a 20-mg/ml hyaluronic acid gel with 0.3% lidocaine, compared to no treatment for the correction of volume deficits in the dorsal hand. This was a prospective, multicenter, split-hand study in 90 subjects who received treatment with product in one hand. The primary efficacy endpoint was based on a 1 point of improvement with treatment versus no treatment according to the Merz Hand Grading Scale at week 12. Other assessments included Central Independent Photographic Reviewers evaluations of hand photographs, Global Aesthetic Improvement Scale, subject satisfaction, and safety. RESULTS:The mean injection volume was 2.1 ml at the first treatment. Subjects demonstrated significantly higher response rates with treatment compared to no treatment at week 12 (85.9 percent versus 21.2 percent) and at weeks 16, 20, and 24 (p < 0.0001). Photographic Reviewers assessments showed consistently greater improvements in the treated hands compared with the untreated hands from week 12 to week 24. Most subjects and investigators (?92.8 percent) reported improvements in Global Aesthetic Improvement Scale score across all time points with treatment. Treatment-related adverse events were reported in seven subjects (7.9 percent). Most of these were mild, and none were serious. CONCLUSION:Hyaluronic acid with lidocaine is safe, effective, and well tolerated for the correction of volume deficits in the dorsal hand. CLINICAL QUESTION/LEVEL OF EVIDENCE:Therapeutic, II.

Project description:It is widely accepted that cerebral pathology can impair ocular motor and manual motor control. This is true in indolent and chronic processes, such as neurodegeneration and in acute processes such as stroke or those secondary to neurotrauma. More recently, it has been suggested that disruptions in these control systems are useful markers for prognostication and longitudinal monitoring. The utility of examining the relationship or the coupling between these systems has yet to be determined. We measured eye and hand-movement control in chronic, middle cerebral artery stroke, relative to healthy controls, in saccade-to-reach paradigms to assess eye-hand coordination. Primary saccades were initiated significantly earlier by stroke participants relative to control participants. However, despite these extremely early initial saccades to the target, reaches were nevertheless initiated at approximately the same time as those of control participants. Control participants minimized the time period between primary saccade onset and reach initiation, demonstrating temporal coupling between eye and hand. In about 90% of all trials, control participants produced no secondary, or corrective, saccades, instead maintaining fixation in the terminal position of the primary saccade until the end of the reach. In contrast, participants with stroke increased the time period between primary saccade onset and reach initiation. During this temporal decoupling, multiple saccades were produced in about 50% of the trials with stroke participants making between one and five additional saccades. Reaches made by participants with stroke were both longer in duration and less accurate. In addition to these increases in spatial reach errors, there were significant increases in saccade endpoint errors. Overall, the magnitude of the endpoint errors for reaches and saccades were correlated across participants. These findings suggest that in individuals with otherwise intact visual function, the spatial and temporal relationships between the eye and hand are disrupted poststroke, and may need to be specifically targeted during neurorehabilitation. Eye-hand coupling may be a useful biomarker in individuals with cerebral pathology in the setting of neurovascular, neurotraumatic, and neurodegenerative pathology.
