Normative Data of Hand Grip Strength in Healthy Adult Pakistani Population

Normative data values of handgrip strength not only describes hand normality but is also used as an objective assessor of upper extremities damages for Occupational Therapy and Physical Therapy interventions. Published normative data of different populations are widely available and can be used as reference. It is evident from different researches that various anthropometric variables such as age, gender, ethnicity, nutritional status, shoulder circumference \& Body Mass Index(BMI), type of occupation and hand dominance of any population influence the hand muscles grip strength. Whereas, some literature shows disparity over the correlation between hand grip strength and BMI, several researchers claiming a positive relationship between BMI and grip strength in all ages of both genders, while other indicates no relationship. Approximately 3000 volunteers will be recruited from the staff, medical students, and visitors of different medical college \& universities of Lahore. Subjects will be excluded if they had a history of upper-limb injury or deformity, or related health conditions. Socioeconomic background, general health, and lifestyle of the subjects will be assessed using a standard questionnaire. Weight, height \& APM thickness will be measured prior to testing. Correlation between Hand Grip Strength and age, weight, height, body mass index (BMI), and Adductor Polices Muscle Thickness (APMT) will be measured. Multiple linear regression analysis will be used to adjust for the effects of other variables and to identify those independently associated with Hand grip strength. All the analysis will be carried out on SPSS v 25.
