Abstract:[Purpose] This study aimed to compare the inter- and intra-examiner reliabilities of toe
grip strength measurements obtained just above the first interphalangeal joint with those
of toe grip strength measurements obtained in the most comfortable position for the
participant. The study also aimed to calculate the minimal detectable change for the more
reliable method. [Participants and Methods] The participants for each test included 20
healthy adult males and females. Intra-class correlation coefficient (1,1) … Show more

[Purpose] Femoral neck fractures are a common problem resulting from balance impairment.
Toe grip strength is related to balance function. This study aimed to confirm the type of
balance function that is highly related to toe grip strength. [Participants and Methods]
The participants included 15 patients who were examined for differences in toe grip
strength between the affected and nonaffected side. The relationship between toe grip
strength and functional balance scale (FBS) and index of postural stability (IPS) was
analyzed. [Results] The result showed no significant difference between the nonaffected
and affected sides. A correlation exists between toe grip strength and FBS and IPS. In
addition, the data from the center-of-gravity sway meter showed a correlation only between
the toe grip strength and anteroposterior diameter of the stable area but not between the
right and left diameters of the stable area and anterior and posterior trajectory lengths.
[Conclusion] No significant difference was found between the affected and nonaffected
sides. The results suggest that toe grip strength is related to the ability to move the
center of gravity forward and backward rather than to sustain the center of gravity.

“…To examine the reliability and the magnitude of measurement error of TFS strength value, 95% limits of agreement (LoA) and minimal detectable change (MDC) were calculated using two values obtained at the first measurement session. 21,22 The MDC was calculated using the following equation.…”

This study aimed to investigate the influence of increases in toe-flexor strength (TFS) through specific training on sprint and jump performances. Design: This study conducted 8 weeks of training with a two-period cross-over design. Methods: Eleven male sprinters performed TFS training (4 weeks, four times per week) which consisted of 6 strength exercises, and 60-m sprint, squat (SJ), countermovement (CMJ) and rebound continuous jumps (RJ), and TFS normalized to body mass were measured before and after the training period. Spatiotemporal and ground reaction force (GRF) variables during the 60-m sprint were also obtained. Results: There were no significant correlations of the normalized TFS with 50-m sprint time (r = 0.363, p = 0.272), SJ (r = 0.119, p = 0.728) and CMJ heights (r = −0.041, p = 0.906), and RJ height (r = 0.368, p = 0.266), contact time (r = −0.215, p = 0.526) and index (r = 0.380, p = 0.249) at the first measurement. Through the TFS training, normalized TFS increased from 0.331 ± 0.071 kg/kg to 0.384 ± 0.086 kg/ kg (16.0%) for the average of two feet. All the sprint and jump performances, as well as the spatiotemporal and GRF variables during sprinting, did not show statistically significant changes through TFS training. Conclusions: These results indicate that, whereas 4 weeks of TFS training could increase normalized TFS for well-trained sprinters, the increase in normalized TFS could not be effective for improving sprint and jump performances for well-trained sprinters.
The purpose of this study was to clarify whether there is a difference between operative and non-operative side toe grip strength of patients with femoral neck fractures, and to examine the reliability and the minimum detectable change (MDC) in toe grip strength measurements. [Participants and Methods] Twenty patients with femoral neck fractures had their toe grip strength measured, and the results were analyzed. [Results] There was no significant difference between the operative and non-operative side toe grip strength. Bland Altman analysis revealed no systematic error. The MDC was 2.1 kg on the operative side and 1.3 kg on the non-operative side.[Conclusion] If the change in toe grip strength of patients after femoral neck fracture surgery is less than 2.1 kg on the operative side and 1.3 kg on the non-operative side, it may be due to a measurement error.
