Debate exists on the anatomical classification of muscles in local and global muscles related to specific functions, respectively segmental stabilizing (local) and torque producing and providing general trunk stability (global), as proposed by Bergmark [ 14].
Trunk stability has neither been addressed.
Muscle activation in therapeutic exercises to improve trunk stability.
The BMS assessed hindlimb function, tail position, trunk stability, and coordination69.
A volitional preemptive abdominal contraction (VPAC) supports trunk stability during functional activity.
Trunk stability was also maximum under these latter forces pulling upward.
The flexed posture in sitting increased the net moment, muscle forces and passive spinal loads while improving the trunk stability.
All players compete in wheelchairs due to a loss of leg function and trunk stability, caused by a lack of muscle co-ordination and control.
The BMS subscore, a cumulative score based off the frequency of stepping, paw position, level of coordination, trunk stability and tail position, was also recorded69.
Based on the specificity principle, sports-related trunk stability tests would be required in elite sports performance.
In conclusion, specific-sport training induces specific trunk stability adaptations, which are not revealed through nonspecific tests.
