제안 방법
- All outcomes (static and dynamic trunk flexor endurance and static and dynamic trunk extensor endurance and flexibility) were measured by a trained physical therapist before and at the end of the exercise program. To prevent fatigue from having a significant impact on scores, the tests that required minimal effort were performed first, and the most strenuous tests were performed last.
- Furthermore, the effects of sling-bridge exercise with PNF technique on trunk muscle endurance and flexibility are unclear. The purpose of this study was to examine the effects of general sling-bridge exercise (GSE) and sling-bridge exercise with rhythmic stabilization technique (SER) on static and dynamic trunk muscle endurance and flexibility in adolescents with LBP.
- Trunk flexion endurance was assessed using the curl-up test [20]. The subjects lay supine with the knees at an angle of 90 degrees (feet fixed by strap) and with arms straight at the sides of the body and pointing toward their knees. To measure the dynamic endurance, subjects performed as many consecutive curl-ups as possible at a rate of 25 per minute to a maximum of 25.
- The subject’s knees were placed in a sling that was suspended from the ceiling. The subjects lift their hip into the air while maintaining straight alignment of the knees, hips and shoulders. The subjects held this position for five seconds and then lowered back to the starting position [14] [Fig.
- The test was used to examine the subjects’ ability to bend forward.
- The two experimental groups (GSE, SER) participated in four weeks program that aimed to improve trunk muscle stability. The training frequency for both groups was five times per week and the training volume per session include three sets of 15 repetitions.
- Therefore, this study assessed trunk muscle (flexor and extensor) endurance (static and dynamic) and trunk flexibility by curl-up test, Biering-Sørensen test and Fingertip-to-Floor Test before and at the end of the exercise program.
- This study compared the effects of sling-bridge exercise with rhythmic stabilization technique and general sling-bridge exercise on trunk muscle endurance and flexibility for adolescents with LBP. The main findings of this study are that SER program is effective in treating adolescent with LBP, when compared to GSE program.
- The number of repetitions performed was recorded. To measure the static endurance, subjects were instructed to trunk extension with maintained a horizontal position as long as possible for maximum of 240 seconds with no rotation or lateral shifting. The length of time holding the upper trunk horizontally was recorded.
- All outcomes (static and dynamic trunk flexor endurance and static and dynamic trunk extensor endurance and flexibility) were measured by a trained physical therapist before and at the end of the exercise program. To prevent fatigue from having a significant impact on scores, the tests that required minimal effort were performed first, and the most strenuous tests were performed last.
대상 데이터
- Thirty adolescents aged 13-19 with a current episode of LBP were recruited to participate in this study. Subjects were eligible for the study if they had a history of recurrent LBP (repeated episodes of pain in past year collectively lasting for less than 6 months) of a nonspecific nature, defined as back pain complaints occurring without identifiable specific anatomical or neurophysiological causative factors [22].
데이터처리
- The results of all experiments were expressed as a mean and standard deviation. Independent t-test was used for the comparison between a GSE group and a SER group. The changes of muscle endurance values in accordance with the lapse of time were analyzed for the comparative verification pre and post-exercise programs in each group using paired t-test was used.
- Independent t-test was used for the comparison between a GSE group and a SER group. The changes of muscle endurance values in accordance with the lapse of time were analyzed for the comparative verification pre and post-exercise programs in each group using paired t-test was used. Statistical significance was recognized with the p value less than 0.
이론/모형
- The experimental design of this study was a randomized controlled trial design. A randomized controlled trial was performed with subjects randomly assigned to one of the two treatment groups: (1) a group that received general sling-bridge exercise (GSE; n=15) or (2) a group that received sling-bridge exercise with rhythmic stabilization technique (SER; n=15).
- To the trunk flexion flexibility measurement, this study used Fingertip-to-Floor Test. Intraclass correlation coefficients for test-retest reliability have been reported as satisfactory, but variability was high [31].
- Trunk extension endurance was assessed using the modification of the Biering-Sørensen test [25].
- Trunk flexibility was assessed using the Fingertip-to-Floor Test [26]. The test was used to examine the subjects’ ability to bend forward.
- Trunk flexion endurance was assessed using the curl-up test [20]. The subjects lay supine with the knees at an angle of 90 degrees (feet fixed by strap) and with arms straight at the sides of the body and pointing toward their knees.
