OBJECTIVES: The two-finger technique (TFT) using the index-middle fingers of the right hand (TFT-R23) was recently confirmed to produce deeper chest compression depth (CCD) compared with the TFT using any other fingers. This study was carried out to confirm whether the TFT-R23 would be as effective as the two-thumb technique (TTT). In addition, individual finger strengths were measured to identify the reasons why the TTT and TFT-R23 produced deeper CCD than any other methods. METHODS: This prospective randomized cross-over trial compared TTT with TFT-R23...

In the assessment of hand and upper limb function, detecting sincerity of effort (SOE) for grip strength is of major importance to identifying feigned loss of strength. Measuring maximal grip strength with a dynamometer is very common, often combined with calculating the coefficient of variation (CV), a measure of the variation over the three grip strength trials. Little data is available about the relevance of these measurements in patients with median nerve impairment due to the heterogeneity of patient groups...

Finger fractures are the most common skeletal injuries of the upper limbs. The purpose of this study was to evaluate the functional outcomes and complications after surgical management of isolated, closed fractures of the proximal phalanx (PP) of the hand (thumb excluded). Surgical management was indicated in 87 PP fractures. Fractures were reduced and fixed with pins, screws or a plate. Functional outcomes were assessed through the range of motion (ROM) in flexion-extension, hand and finger strength, and the QuickDASH and PRWHE scores...

Recently, a few small reports with short follow-up period have shown clinical benefits of platelet-rich plasma (PRP) for peripheral neuropathy including one pilot study and one small, non-randomized trial in patients with carpal tunnel syndrome (CTS). Therefore, we conducted a randomized, single-blind, controlled trial to assess the 6-month effect of PRP in patients with CTS. Sixty patients with unilateral mild-to-moderate CTS were randomized into two groups of 30, namely the PRP and control groups. In the PRP group, patients were injected with one dose of 3 mL of PRP using ultrasound guidance and the control group received a night splint through the study period...

Every year, thousands of Americans suffer from pathological and traumatic events that result in loss of dexterity and strength of the hand. Although many supportive devices have been designed to restore functional hand movement, most are very complex and expensive. The goal of this project was to design and implement a cost-effective, electrically powered exoskeleton for the human hand that could improve grasping strength. A 3-D printed thermoplastic exoskeleton that allowed independent and enhanced movement of the index, middle and ring fingers was constructed...

It has been argued that disorders in body-ownership and aberrant experiences in self-consciousness are due to biases in multisensory integration. Here we examine whether such biases are also associated with spontaneous out-of-body experiences (OBEs) in a nonclinical population. One-hundred and 80 participants took part in a rubber hand illusion (RHI) experiment with synchronous and asynchronous visual and tactile stimulation. A realistic threat was delivered to the rubber hand after a fixed period of stimulation...

Carpal tunnel syndrome(CTS) is the most common neuromuscular cause of upper extremity disability. We aimed to investigate the effectiveness of peloid therapy in patients with CTS. This randomized, controlled, single-blind study enrolled 70 patients between the ages of 30 to 65 who had a diagnosis of either mild, mild-to-moderate, or moderate CTS. The patients were randomized into two groups using random number table. In the first group, (Group 1)(n = 35), patients were given splint (every night for 6 weeks) + peloid treatment(five consecutive days a week for 2 weeks) and in the second group, (Group 2)(n = 28), patients received splint treatment(every night for 6 weeks) alone...

BACKGROUND: Finger injuries are common in the sport of hurling. Injury to the little finger distal interphalangeal joint (DIPJ) often occurs when a high dropping ball impacts on the outstretched finger. The little finger contributes to approximately 15% of grip strength. Injury therefore results in reduced grip strength and may impair the ability of players to grip or catch a ball. METHODS: Six elite hurlers with post-traumatic arthritis of their non-dominant little finger DIPJ underwent arthrodesis in 30 degrees of flexion...

Polyvinylidene fluoride (PVDF) membrane has been widely applied in water and wastewater treatment because of its high mechanical strength, thermal stability and chemical resistance. However, the hydrophobic nature of PVDF membrane makes it readily fouled, substantially reducing water flux and overall membrane rejection ability. In this work, an in-situ blending modifier, i.e., extracellular polymeric substances (EPS) from activated sludge, was used to enhance the anti-fouling ability of PVDF membrane. Results indicate that the pure water flux of the membrane and its anti-fouling performance were substantially improved by blending 8% EPS into the membrane...

The Strength-Dexterity (SD) test measures the ability of the pulps of the thumb and index finger to compress a compliant and slender spring prone to buckling at low forces (<3N). We know that factors such as aging and neurodegenerative conditions bring deteriorating physiological changes (e.g., at the level of motor cortex, cerebellum, and basal ganglia), which lead to an overall loss of dexterous ability. However, little is known about how these changes reflect upon the dynamics of the underlying biological system...
