The purpose was to determine if pull-up performance was affected by the use of chalk (100% magnesium carbonate) during open-handed and pinch grip weight-assisted pull-ups (WAPU) in recreationally-trained rock climbers. Furthermore, the reliability of open-handed and pinch grip WAPU was also investigated. Recreationally-active volunteers (n = 9) completed six counterbalanced trials. Participants...

BACKGROUND With the severity of machine hand injuries in our environment, the need to determine the normal values for key pinch strength with which to compare restorative surgeries was justified. METHOD A cross sectional survey of participants who had no previous hand injuries limiting hand function. Data obtained included age, gender, body mass index, hand dominance and hand span. The Baseli...

Particularly interesting new cysteine- histidine- rich protein (PINCH) is an adaptor protein that our data have shown is required for neurite extension under stressful conditions. Our previous studies also report that PINCH is recalled by neurons showing decreased levels of synaptodendritic signaling proteins such as MAP2 or synaptophysin in the brains of human immunodeficiency virus (HIV) pati...

OBJECTIVES To explore the ability of six outcome measures to capture clinically important changes in patients with rheumatic diseases undergoing hand surgery and to study predictors of changes in activity performance in different patient and surgery strata. METHODS A total of 172 patients (median age 59 years, disease duration 18 years) were stratified into subgroups: diagnosis, age, general ...

This paper presents a new method to calculate the freshwater target for water using networks with single contaminant. The pinch point is determined by exploiting one of the features of water-pinch-analysis: freshwater is only necessary below the pinch. With the known pinch point, the calculation of the freshwater target becomes very simple, especially for the networks with many streams. The res...

Quipazine is a 5-HT2A-receptor agonist that has been used to induce motor activity and promote recovery of function after spinal cord injury in neonatal and adult rodents. Sensory stimulation also activates sensory and motor circuits and promotes recovery after spinal cord injury. In rats, tail pinching is an effective and robust method of sacrocaudal sensory afferent stimulation that induces m...

A variety of human diseases arise from mutations that alter muscle contraction. Evolutionary conservation allows genetic studies in Drosophila melanogaster to be used to better understand these myopathies and suggest novel therapeutic strategies. Integrin-mediated adhesion is required to support muscle structure and function, and expression of Integrin adhesive complex (IAC) proteins is modulat...

Objectives: Carpal tunnel syndrome (CTS) is a common peripheral entrapment neuropathy with squeezing of the median nerve and the patient is unable to function properly. There are different physiotherapy interventions for the management of these patients and recently, shock wave therapy and low-power laser (LPL) have been widely used, but there is no strong evidence comparing the effect of shock...
