Joint cracking involves a manipulation of the finger joints resulting in an audible crack. This study aimed to determine whether habitual knuckle cracking (KC) leads to an alteration in grip strength and metacarpal head (MH) cartilage thickness. Thirty-five habitual knuckle crackers (cracking their joints ≥5times/day) (20 M, 15 F, aged 19-27 years) and 35 age-, gender-, and body mass index-matched non-crackers were enrolled in the study. MH cartilage thickness was measured with ultrasound and grip strength was measured with an analog Jamar hand dynamometer...

CONCLUSIONS: One third of the patients had cachexia with an association of significantly shorter survival. These results suggest that combining HGS and MAMA seems to be a practical method to screen cachexia in patients with head and neck cancer and may also be used when assessing their prognosis. OBJECTIVES: The aim of this study was to analyze the hypothesis that cachexia defined as both low mid-arm muscle area (MAMA) and handgrip strength (HGS) is associated with decreased survival in patients with head and neck squamous cell carcinoma (HNSCC)...

Some patients with chronic inflammatory demyelinating polyradiculoneuropathy who respond to initial intravenous immunoglobulin require repeated courses over prolonged periods of time; however, evidence to guide dosage and interval of intravenous immunoglobulin during maintenance therapy is limited. Optimizing treatment requires assessment of underlying disease activity and clinical outcome. Electrophysiological measures of demyelination, and clinical measures using handgrip strength and walking velocity promise to be particularly informative...

BACKGROUND: National sporting achievement at the Olympic Games is important for national pride and prestige, and to promote participation in sport. Summer Olympic Games medal tallies have been associated with national wealth, and also social development and healthcare expenditure. It is uncertain however, how these socioeconomic factors translate into Olympic success. The objective of this study was therefore to examine the relationship between population muscle strength and Olympic medal tallies...
