INTRODUCTION: During grasping, the median nerve undergoes mechanical stress in the carpal tunnel which may contribute to carpal tunnel syndrome. This study investigated the effects of wrist posture, grip type, and grip force on the shape and cross-sectional area of the median nerve. MATERIALS AND METHODS: Ultrasound examination was used to obtain cross-sectional images of the dominant wrist of 16 healthy subjects (8 male) at the proximal carpal tunnel during grasping...

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...

BACKGROUND: Peripheral lesions of the median nerve cause characteristic changes of the grip function of the hand. For evaluating grip force changes, measurement by dynamometers (JAMAR dynamometer and pinch dynamometer) is of high relevance. In this study the ability of grip force measurements of different grip forms was evaluated to discriminate between a simulated median nerve lesion and healthy subjects. MATERIAL AND METHODS: In 21 healthy subjects, the grip force of power grip was measured by the JAMAR dynamometer at the second stage including measurement of force at the fingertips and the thenar by a sensor glove...

BACKGROUND: Trapeziometacarpal arthrodesis (TMA) has been complicated by nonunion and hardware failure. QUESTIONS/PURPOSES: We hypothesized that modification of the TMA technique with a locking cage plate construct would afford reliable bony union while producing greater hand function than trapeziectomy with ligament reconstruction and tendon interposition (LRTI) at early follow-up. METHODS: We enrolled 36 consecutive patients with trapeziometacapal osteoarthritis (14 TMA patients (15 thumbs), 22 LRTI patients (22 thumbs))...

BACKGROUND: Fingertip amputation in children is difficult to manage using microsurgical replantation techniques and many salvage procedures have failed owing to the nonavailability of suitable veins for anastomosis in the fingertip. This study reviewed our experience of pediatric fingertip replantation involving palmar venous anastomoses and evaluated the clinical outcomes. METHODS: From October 2008 to May 2013, 21 pediatric fingertips that had been completely amputated at or distal to the distal interphalangeal joint of the finger, or at or distal to the interphalangeal joint of the thumb were managed using complete replantation...

INTRODUCTION: In the assessment of hand and upper limb function, grip strength is of major importance. Use of the JAMAR dynamometer has been an accepted test of grip strength and routinely part of the physical examination. PURPOSE OF THE STUDY: The aim of this study was to determine by means of a median nerve block simulating a patient group if the measurement of different types of grip force can improve the quantification of impairment of the hand beyond the sole power grip measurements...

PURPOSE: Concurrent carpal tunnel syndrome and pronator syndrome are rarely considered and the proximal compression sites are easily overlooked. We retrospectively studied 21 concurrent cases in our series from 2009 to 2015 and report the results. PATIENTS AND METHODS: The typical symptoms were pain, tingling, and numbness of the radial 3½ digits. If paresthesia involved the thenar eminence and proximal forearm pain was noted in cases of carpal tunnel syndrome, carpal tunnel syndrome combined with pronator syndrome was considered...

BACKGROUND: Following neuropathy α2-adrenoceptor-mediated diffuse noxious inhibitory controls (DNIC), whereby a noxious conditioning stimulus inhibits the activity of spinal wide dynamic range (WDR) neurons, are abolished, and spinal 5-HT7 receptor densities are increased. Here, we manipulate spinal 5-HT content in spinal nerve ligated (SNL) animals and investigate which 5-HT receptor mediated actions predominate. METHODS: Using in vivo electrophysiology we recorded WDR neuronal responses to von frey filaments applied to the hind paw before, and concurrent to, a noxious ear pinch (the conditioning stimulus) in isoflurane-anaesthetised rats...

C7-T1 brachial plexus palsies result in a loss of finger motion and hand function. The authors have observed that finger flexion motion can be recovered after a brachialis motor branch transfer. However, finger flexion strength after this procedure merely corresponds to Medical Research Council Grades M2-M3, lowering the grip strength and practical value of the reconstructed hand. Therefore, they used 2 donor nerves and accomplished double nerve transfers for stronger finger flexion. In a patient with a C7-T1 brachial plexus injury, they transferred the pronator teres branch to the anterior interosseous nerve and the brachialis motor branch to the flexor digitorum superficialis branch for reinnervation of full finger flexors...

Various studies have reported that galanin can promote axonal regeneration of dorsal root ganglion neurons in vitro and inhibit neuropathic pain. However, little is known about its effects on diabetic peripheral neuropathy, and in vivo experimental data are lacking. We hypothesized that repeated applications of exogenous galanin over an extended time frame may also repair nerve damage in diabetic peripheral neuropathy, and relieve pain in vivo. We found that neuropathic pain occurred in streptozotocin-induced diabetic rats and was more severe after sciatic nerve pinch injury at 14 and 28 days than in diabetic sham-operated rats...

Study Design Case report. Background Multifocal motor neuropathy is a progressive motor nerve disorder characterized by muscle weakness in the extremities. Muscle imbalance and weakness can become so severe that the involved extremity can be rendered nonfunctional. The purpose of this case report is to describe the physical therapy postoperative management of a patient who underwent a multiple tendon transfer to correct the loss of digital/wrist extension of the right upper extremity. Case Description A 38-year-old woman with a medical diagnosis of multifocal motor neuropathy, which caused muscle imbalance and weakness in the right hand, underwent a multiple tendon transfer to correct the loss of digit and wrist extension...

Many organisms respond to noxious stimuli with defensive maneuvers. This is noted in the hornworm, Manduca sexta, as a defensive strike response. After tissue damage, organisms typically display sensitized responses to both noxious or normally innocuous stimuli. To further understand this phenomenon, we used novel in situ and in vitro preparations based on paired extracellular nerve recordings and videography to identify central and peripheral nerves responsible for nociception and sensitization of the defensive behavior in M...
