Test-retest reliability of static and dynamic motor fatigability protocols using grip and pinch strength in typically developing children

Upper limb motor fatigability is an important debilitating factor for activities of daily living in clinical pediatric populations. However, the reliability protocols these populations currently unknown. Therefore, current study investigates test-retest a static and dynamic protocol grip pinch strength typically developing children (TDC). Eighty-nine TDC (35 boys, 54 girls; mean age 10 years 11 months) used dynamometer (sustained) (repeated) contractions during 30s. For (SFI), (Fmean) SD (Fvar) force were calculated, fatigability, F number peaks (Npeaks) calculated. Intraclass correlation coefficients (ICC) ICCs high (ICC: 0.94–0.96 0.91–0.98). moderate to var 0.67–0.85). The SFI showed 0.69–0.77). N 0.78–0.91). Conclusion: results suggest that can be reliably TD aged 6–18 years.
