Hand grip strength (HGS) measurements serve as an objective measure of upper extremity function. Reliable hand strength evaluation is vital for assessing treatment effectiveness.
To determine the influence of hand dominance, gender, and body mass index (BMI) on HGS among university students in Ghana.
In our cross-sectional study of 304 participants, height, weight, and BMI were measured using a stadiometer and weighing scale. Hand grip strength was assessed with a dynamometer. We compared HGS in dominant and non-dominant hands for males and females using a paired -test and analysed the correlation between grip strength and weight, height, and BMI using Pearson's correlation coefficient.
The mean HGS for right-hand dominant (RHD) male participants was 35.62 kg (± 7.36) for the right hand compared with 32.84 kg (± 7.36) for the left hand. For females RHD the mean HGS in the right hand was 24.60 kg (± 6.42) compared to 22.12 kg (± 5.37) in the left hand. The mean weight, height and BMI of participants were 62.86 kg (± 10.30), 1.67 m (± 0.09) and 22.9 kg/m (± 4.9), respectively. A significant relationship existed between HGS and height ( = 0.492; < 0.01) as well as HGS and BMI ( = 0.290; < 0.01). However, no notable connection was found between HGS and weight ( = 0.001; = 0.982).
Hand grip strength was significantly stronger in the dominant hand of both males and females.
Physiotherapists should test HGS objectively and quantitatively for use in disease evaluation, diagnosis, and therapy.
握力（HGS）测量是上肢功能的客观指标。可靠的手部力量评估对于评估治疗效果至关重要。
确定在加纳大学生中，利手、性别和体重指数（BMI）对握力的影响。
在我们对304名参与者的横断面研究中，使用身高计和体重秤测量身高、体重和BMI。用握力计评估握力。我们使用配对t检验比较男性和女性优势手与非优势手的握力，并使用Pearson相关系数分析握力与体重、身高和BMI之间的相关性。
右手优势（RHD）男性参与者右手的平均握力为35.62千克（±7.36），左手为32.84千克（±7.36）。对于右手优势的女性，右手平均握力为24.60千克（±6.42），左手为22.12千克（±5.37）。参与者的平均体重、身高和BMI分别为62.86千克（±10.30）、1.67米（±0.09）和22.9千克/平方米（±4.9）。握力与身高（r = 0.492；P < 0.01）以及握力与BMI（r = 0.290；P < 0.01）之间存在显著关系。然而，未发现握力与体重之间有显著关联（r = 0.001；P = 0.982）。
男性和女性的优势手的握力明显更强。
物理治疗师应客观、定量地测试握力，以用于疾病评估、诊断和治疗。
