Hip-strength assessment is fundamental in the clinical examination to predict musculoskeletal injuries in athletes.
Hand-held dynamometry is a quantitative method often used for assessing hip muscle function.
Intestester reliability is generally good-to-excellent in disabled populations, however, it is an unknown topic for soccer players.
The Aim of the Study
The aim of this study was to examine the intertester measurement variation concerning strength assessment of hip abduction and adduction in soccer players.
Interestingly, the intertester reliability values was ” good ” to ” moderate ” for hip ABD and ADD isometric strength.
These results suggest that the hand dynamometer allows an adequate assessment of the ABD and ADD hip musculature.
29 subjects were senior football players (mean age 23,8 years, ranged from 19 to 35 years). Only participants with no history of injury to the hip and groin region were included.
In the study we used two baseline push pull dynamometer manual which were calibrated on each measure and all test procedures were standardized.
Two tester performed isometric strength measurements to each of the participants, establishing a rest period of 5 minutes between each measurement. For each movement intertester correlation coefficients were calculated.
What the Results Showed
Intertester agreement ranged from limits of agreement between [-9,3 – 22,4 lbr] for ABD muscles, and [-8,7 – 18,6 lbr] for ADD muscles.
Analyses of means scores between testers reveal significant differences. CCI ranged between 0,58 and 0,68 for ABD muscles and between 0,67 and 0,69 for ADD muscles.
Practical Application
- Intertester reliability values was “good” to “moderate” for hip ABD and ADD isometric strength within soccer players.
- These results suggest that the hand dynamometer allows and adequate assessment of the ABD and ADD hip musculature within soccer player cohorts.
