Muscular fatigue impacts on normal shoulder function, which is particularly pertinent to throwing athletes. This study aimed to investigate the relationship between grip strength and shoulder muscle… Expand
Evidence-Based Treatment of Madelung’s Deformity
Madelung’s deformity is a premature growth arrest of the volar ulna aspect of the radial growth plate leading to ulna overgrowth and a progressive wrist deformity. Treatment depends on the skeletal… Expand
Muscle strength and its relationship with skeletal muscle mass indices as determined by segmental bio-impedance analysis
- O. Alizadehkhaiyat, D. Hawkes, G. Kemp, A. Howard, S. Frostick
- Medicine
- European Journal of Applied Physiology
- 2013
PurposeDespite increasing interest in bio-impedance analysis (BIA) for estimation of segmental skeletal muscle mass (SMM), published results have not been entirely convincing. Furthermore, a better… Expand
