These results suggest that wrist ROM and grip strength should be evaluated in different positions of forearm rotation, rather than a fixed position. All measurements differed with forearm rotation and were not influenced by hand dominance.
Whereas there was no difference in radial deviation with forearm position in females, it was markedly greater in pronation versus supination on both sides in males (nondominant: supination 16.3°, pronation 24.6° dominant: supination 15.4°, pronation 23.9°).Ĭonclusion This study characterizes variations in grip strength and wrist ROM in three forearm positions in healthy young individuals. It is normal to feel some discomfort at first, but you should not feel pain.

Ulnar deviation in males did not differ with forearm position, but females demonstrated greater ulnar deviation in supination on the nondominant hand (supination 44.6°, pronation 33.2°). These exercises help you move each joint through its full range of motion. Wrist extension in males was greater in pronation (supination 64.6°, pronation 69.5°) whereas females showed no significant difference in any of the forearm positions. Wrist flexion in males was significantly reduced in supination compared with neutral and pronated positions (nondominant: supination 63.1°, neutral 72.6°, pronation 73.3° dominant: supination 62.4°, neutral 70.2°, pronation 70.3°), whereas not significant wrist flexion in females was also weaker in supination (supination 74.4°, neutral 79.9°). Grip strength in females was similar between supination (nondominant: 26.1 kg, dominant: 28.5 kg) and neutral (nondominant: 27.4 kg, dominant: 29.1 kg) positions, but both were greater than in pronation (nondominant: 22.3 kg, dominant: 24.1 kg). Results Grip strength in males was greatest in neutral position (males: nondominant 51.4 kg, dominant 56.1 kg) followed by supination (males: nondominant 46.6 kg, dominant 51.7 kg) and weakest in pronation (males: nondominant 40.1 kg, dominant 42.9 kg). Forearm position values were compared using post hoc analysis. Data analysis was conducted using a one-way repeated measure ANOVA. Participant demographics, grip strength, and wrist ROM (wrist flexion and extension, ulnar and radial deviation) at three forearm positions (full supination, neutral, and full pronation) were measured using a digital dynamometer and standard goniometers. Materials and Methods Wrist ROM and grip strength were measured in 30 healthy volunteers aged 23 to 30.
This study aims to identify and quantify variations in grip strength and wrist ROM with forearm rotation in healthy young individuals. Published normative data on these metrics do not recognize the contribution of forearm rotation.
