The purpose of this study was to investigate the short-term effects of lumbar rotational mobilization under the single-leg standing (SLS) position. Fifteen healthy individuals were recruited, and randomized to agroup of trunk rotational exercise (TRE) and lumbar rotational mobilization (LRM). Trunk twist rotational exercise was performed to the TRE group, and mobilization was applied to the LRM group on the lumbar spine. Velocity of the center of pressure (VCOP) and center of pressure (COP) for each participant were measured through SLS. COPs were not significantly increased or decreased after treatment in both groups. VCOPs also did not change considerably except on the right side when the eye was closed. There was no significant difference between COPs and VCOPs in two groups. This study suggests that trunk rotation exercise and lumbar rotation mobilization would have similar effects on balance ability.

문제 정의

The purpose of this study was to evaluate the short-term effects of lumbar rotation mobilization on the SLS ability. In this finding, lumbar rotation mobilization (LRM) could serve to decreasing COP and VCOP during SLS balance.
This study is a single-center, double-blinded, randomized controlledclinical study. All individuals participating in lumbar rotational mobilization (LRM) and trunk rotational exercise (TRE) were measured before and after interventions.

가설 설정

In addition, there is alittle evidence to support the rationale for the reason of effect onto lumbar mobilization on balance ability. For these reasons, this study hypothesized that physiological lumbar rotation also caused neurophysiologic changes like other vertebral mobilization, which in turn would affect balance.

제안 방법

The effect of an intervention on SLS was measured by the platform (RM Ingenierie, France). After the 8-day wash-out period, those who participated in the LRM performed the TRE, and those who participated in the TRE performed the LRM. All of the dependent variables were measured in the same manner four times.
This study is a single-center, double-blinded, randomized controlledclinical study. All individuals participating in lumbar rotational mobilization (LRM) and trunk rotational exercise (TRE) were measured before and after interventions. After each trial, they had eight days of wash-out periods.
Randomly allocated data groups were performed after the measurement by an appointed teaching assistant working at IUK using opaque envelops, in blocks of 2 participants, to ensure a blind in each group; independent evaluators were appointed, who performed all the evaluations in a single-blind manner. They were not involved in the allocation procedure or treatment of either the LRM or TRE group.
For example, if the area is large and the speed is high, the balance ability is decreased. The examination and treatment were carried out by different persons in all experimental procedures.
14) agreed to be participated in this study. This study included persons who could stand with a left foot within 20 seconds and had no pain in their legs, buttocks, and backs. Participants who underwent surgery around the hip, hip, or hip within 12 months were excluded.

대상 데이터

Participants who underwent surgery around the hip, hip, or hip within 12 months were excluded. The final participants are 15 people. The dominant foot of the participant estimated right side.

0 to study the effects of spinal mobilization on the dependent variables – COP and VCOP. The paired t-test is used to test the significance mean the difference between each group and the independent test is used to test the significant mean difference between the groups.Statistical significance was accepted at the 5% of the level.

이론/모형

Right and left rotation mobilization techniques (grade 3 and grade 4) described by Maitland³⁴⁾ applied on from lumbar vertebra 1 to 5 for ten minutes in this study. The participants were introduced to each side-lying position on the plinth for 5 minutes.
After each trial, they had eight days of wash-out periods. Single-Legged Balance (SLB) test was chosen to make outcomes (Fig. 1).
Thestatistical analysis was performed with SPSS Version 20.0 to study the effects of spinal mobilization on the dependent variables – COP and VCOP.

성능/효과

The changes between the groups are as follows. After the intervention, the variables were generally higher the COP of TRE than in the LRM with an eye open, and COP of LRM was increased compared with TRE when left foot standing with an eye closed.
In other words, decreasing COP and VCOP mean improved balance. In conclusion, the findings of this study suggest that LRM is a more effective method than TRE.
There are some possible explanations for our result.The results of this study indicate that the COP and VCOP of the LRM decreased when standing with an eye open, however, increased during standing with the left foot in eye closed. In contrast, the COP of the TRE decreased or increased in an uncertain pattern.
