No results posted yet for this study

Summary

his study aims to establish reference values and examine the reliability of handgrip strength assessment using a digital dynamometer (VALD DynaMo) in healthy adolescents.

Participants will undergo standardized strength evaluations of upper and lower limbs, following international testing guidelines.

Descriptive variables such as age, sex, height, weight, hand dominance, and physical activity level will also be recorded.

The results will contribute to developing normative data and validating the use of portable dynamometry for musculoskeletal health assessment, with potential future applications in clinical populations.

DIAGNOSTIC_TEST

Muscle Strength Assessment using Digital Handheld Dynamometry (VALD Dynamo®)

All participants (healthy or clinical) will perform standardized muscle strength tests using the VALD Dynamo® digital dynamometer. For upper limb assessments, the protocol will follow the American Society of Hand Therapists (ASHT) recommendations (shoulder neutral, elbow 90°, forearm neutral, wrist 0-30° extension, 0-15° ulnar deviation). Lower limb tests will include validated isometric protocols for major muscle groups (quadriceps, hamstrings, hip abductors/adductors). Each test will include three maximal voluntary contractions (3 seconds each) with 60 seconds of rest between trials. Data will be used to analyze intra- and inter-session reliability, normative reference values, and potential clinical applicability.
