[Purpose] To study the correlation among proprioception, muscle strength, and balance.
[Subjects and Methods] A balance testing system (Biodex Balance System, BBS) and an
isokinetic testing system (Biodex System 4, BS4) were used to test related indexes in 24
healthy young females. [Results] With the knee joint at 15 degree flexion, proprioception
was significantly correlated with Limits of Stability-Time values, and was highly
significantly correlated with Limits of Stability-Overall and Athlete Single Leg
Medial/Lateral values. The sense of force was significantly correlated with Limits of
Stability-Overall and Athlete Single Leg-Overall values. Quadriceps strength was
significantly associated with Limits of Stability-Overall, Athlete Single Leg
Medial/Lateral, and Athlete Double Leg-Overall values. The ratio of Quadriceps to
Hamstring strength was significantly correlated with Athlete Single Leg Medial/Lateral,
and Athlete Single Leg-Overall values. With the knee joint at 45°, proprioception was
highly significantly correlated with dynamic balance, and was significantly correlated
with double foot support under static balance; force sense had a high correlation with
Limits of Stability-Overall, but no correlation with other indexes. Quadriceps strength
had a significant correlation with dynamic and static balance; the ratio of
Quadriceps/Hamstring had a highly significant correlation with Limits of
Stability-Overall, Athlete Single Leg-Anterior/Posterior and Athlete Single Leg-Overall.
[Conclusion] At different knee angles, the correlation differs among proprioception, force
sense, quadriceps strength, the Quadriceps/Hamstring ratio, and balance.
The authors' aim was to find the features of balance, proprioception, and gross motor development of Chinese children 3-6 years old and their correlations, provide theoretical support for promoting children's motor development, and enrich the world theoretical system of motor development. This study used a Tekscan foot pressure measurement instrument (Tekscan, Inc., Boston, MA), walking on a balance beam, Xsens 3-dimensional positional measuring system (Xsens Technologies, Enschede, the Netherlands), and Test of Gross Motor Development-2 to assess static balance, dynamic balance, knee proprioception, and levels of gross motor development (GMD) of 3- to 6-year-old children (n = 60) in Beijing. The results are as follows: children had significant age differences in static balance, dynamic balance, proprioception, and levels of GMD; children had significant gender differences in static balance, proprioception, and levels of GMD; children's static balance, dynamic balance, and proprioception had a very significant positive correlation with GMD (p< .01), but no significant correlation with body mass index.
[Purpose] To study the correlation of the results obtained from different proprioception
test methods, namely, the joint angle reset method, the motion minimum threshold
measurement method, and the force sense reproduction method, performed on the same
subjects’ knees. [Subjects and Methods] Different proprioception test methods, the joint
angle reset method, the motion minimum threshold measurement method and the force sense
reproduction method were used to test the knees of 30 healthy young men. [Results]
Correlations were found in the following descending order from strong to weak: the
correlation between the joint angle reset method and the force sense reproduction method
(correlation coefficient of 0.41), the correlation between the joint angle reset method
and the motion minimum threshold measurement method (correlation coefficient of 0.29), the
correlation between the motion minimum threshold measurement method and the force sense
reproduce method (correlation coefficient of 0.15). [Conclusion] No correlation was found
among the results obtained using the joint angle reset method, the motion minimum
threshold measurement method and the force sense reproduction method. Therefore, no
correlation was found among the position sense, the motion sense and the force sense
represented by these methods. Using the results of only one of the test methods to
represent proprioception is one-sided. Force sensation depends more on the sensory input
of information from the Golgi tendon organs, motion sense depends more on the input
information of the muscle spindles, and position sense relies on the double input
information of the muscle spindles and the Golgi tendon organs.
