Background:
The glenohumeral joint is the most mobile of the body economy. It is due to the laxity of the joint capsule and shallowness of the glenoid in relation to the large size of the humeral head, within the high mobility that owns it is important to determine the normal muscular force. This paper presents a preliminary database of shoulder abduction strength in healthy patients. The aim of this paper is to determine the strength of shoulder abduction in Mexican healthy patients.
Methods:
Individuals without shoulder diseases or cervical spine known, in an age range of 18-65 years old, male and female, organized into 5 groups were included. Anthropometric measurements and abduction strength test on both shoulders (Kg / force) were performed. The variables were analyzed statistically with r of Pearson and Spearman p < 0.05.
Results:
Analysis by age group, gender and the dominant and nondominant arm, the maximum force to the dominant arm in male was 26-35 years group with 7.11 Kg/force, while for the same genre nondominant arm was 46-55 years group with 8.04 Kg/force; the maximum force to the dominant arm in female was 26-35 years group with 4.35 Kg/force while for the non-dominant arm of the same gender group was 18-25 with 4.43 Kg/force. Positive correlation of force was observed with the weight and height, as well as the circumference of the wrist.
Conclusions:
The analysis of abduction strength in healthy patients by age group created a preliminary database will be a framework in acute and chronic shoulder pathology.
