Summary
Hip flexor and extensor strength can be reliably measured using a hand-held dynamometer across different postures. This simple method provides consistent results for assessing hip muscle strength in healthy adults.
Area of Science:
- Kinesiology
- Biomechanics
- Musculoskeletal Research
Background:
- Assessing hip flexor and extensor strength is crucial for understanding lower limb function.
- Standardized measurement techniques are needed for reliable strength evaluation.
Purpose of the Study:
- To evaluate hip flexor and extensor muscle strength using varied posture measurements.
- To determine the reliability of hand-held dynamometry for hip strength assessment.
Main Methods:
- Healthy adults (26 males, 24 females) participated.
- Hip flexor and extensor strengths were measured using a hand-held dynamometer in multiple postures.
- Manual Muscle Testing procedures were followed, with comparisons across sexes and postures.
Main Results:
- Intraclass correlation coefficients exceeded 0.7, indicating good measurement reliability.
- No significant differences in hip strength were found between males and females.
- Significant differences were observed in right/left hip flexor and left hip extensor strength.
Conclusions:
- Hand-held dynamometry offers a simple and accessible method for measuring hip flexor and extensor strength.
- The technique demonstrates good reliability for strength assessment in diverse postures.
