Abstract ▼ AI-Helper

Purpose : The purpose of this paper is to compare the immediate effects of tensor fascia latae (TFL) stretching with weight bearing (standing position) or non-weight bearing (side-lying position). Methods : The study was conducted on 30 adults (12 men, 18 women) in their 20s. Modified Thomas's test was conducted to find out if the TFL muscle has a tightness for current study. This study randomly divided the subjects into two groups and set the standing stretching group (n=15) or the side-lying stretching group (n=15). Both groups applied self-stretching under the therapist's supervision. TFL stretching in each positions was performed 30 seconds per set, 3 times, and 30 seconds per set could rest. The Ober test were conducted to investigate the effect of TFL stretching in each positions. Results : For the Ober test measurements within each group, both groups significantly increased after intervention compared to before (p.05). Conclusion : TFL stretching in standing position and side-lying position increased the range of motion of the TFL muscle. Therefore, if it is difficult to apply TFL stretching in standing position (weight bearing) due to pain or other reasons, it will be able to TFL stretching in side-lying position (non-weight bearing).

문제 정의

In this study, we identified the immediate effects of TFL stretching in standing position and side-lying position in the persons with TFL tights. For the Ober test measurements within each group, both groups (standing and side-lying stretching groups) significantly increased after intervention compared to before (p<.

, 2011). The results create a question of whether weight bearing stretching makes different result compared with non-weight bearing stretching or not. However, so far, studies are very limited to distinguish between weight bearing stretching and non-weight bearing stretching for TFL muscles.

제안 방법

After bending the knee joint, the therapist held subject's pelvis with one hand, and made it extension and external rotation of the hip joint, and then performed the hip adduction.
(2017) article showed that TFL muscle shortening may have caused pain in the waist or pelvic region, since the average age in the study was in their 40s. On the other hand, the subjects of this study were in their 20s, so there was a shortening of the TFL, but other tissues around them would have supplemented it. In other words, muscle volume, ligaments and smooth blood circulation would have complemented the tightness of the TFL, which in turn would have produced similar results between the two groups as they did not reach for experiencing ITBS.
The present study was conducted on 30 adults (12 men, 18 women) in their 20s. The study participants were chosen to have no experience of serious leg injury and had a tightness of the TFL muscle. Modified Thomas's test was conducted to find out if the TFL muscle has a tightness.
Second, there is a few TFL stretching papers comparing, standing and side-lying positions. Third, using only one plastic ruler and a mobile phone application used to measure the angle of hip joint adduction for conducting the study. We think more people will have suggested a way to apply this intervention for a TFL stretching method.
This study conducted an Ober test to find out the effects of TFL stretching according to weight bearing of the subjects (Reese & Bandy, 2003; Willett et al., 2016).
This study conducted an Ober test to find out the immediate effect of the TFL stretching, whether weight bearing (standing stretching position) or not (side-lying stretching position), and TFL stretching of both positions increased TFL ROM after the intervention. Authors think that this study is considered to have clinical meaning.
To find out the effect of weight bearing stretching and non-weight bearing stretching on TFL muscle, we randomly divided the subjects into two groups; TFL standing stretching group (n=15), and TFL side-lying stretching group (n=15). Table 1 shows the general characteristics of subjects in current study.

대상 데이터

The present study was conducted on 30 adults (12 men, 18 women) in their 20s. The study participants were chosen to have no experience of serious leg injury and had a tightness of the TFL muscle.
When passive hip adduction was applied in this position after thigh were lowered to the horizontal, persons who did not reach 15~20 ° were selected as the subjects (Tunnell, 1998)(Fig 1-A).

, Chicago IL, USA), and the values of each data represent the Mean±SD. In order to compare the differences between the standing stretching group and the side-lying stretching group, an independent t-test was performed, and paired t-test was conducted to identify the effects of intervention before and after each group. The statistical significance level α was set at .

이론/모형

The Ober test was conducted twice, and the average value was used as data. To measure the hip ROM, a plastic roller and a phone application Clinometer (Clinometer, Plaincode^TM, Germany) were used.

성능/효과

First, this article shows that the subjects who have unstable knee joint and have lower extremity’ pain have another option to apply TFL muscle stretching. From the results of this study, TFL stretching showed effects in the both positions (standing and side-lying) to muscle length. Therefore, if it is difficult to TFL stretching due to lower extremity’s instability in standing position, it will be able to TFL stretching in side-lying position.

후속연구

This also be a limitation of this study. Thus, further studies should show more direct results based on posture not only in the shortening of the TFL but also in the presence of pain when selecting the subjects. However, this study is considered to have clinical meaning.
