Background: Spinal Mobilization is one of the manual therapy technique that clinicians have used to treat pain, however, there is still a lack of research on changes in strength in healthy people. Objectives: To investigate the effect of posterior-anterior lumbar mobilization on lower limb strength in healthy individuals. Design: Two-group pretest-posttest design. Methods: In this study, 23 healthy subjects aged 20 years were assigned to 12 lumbar mobilization group (LMG) and 12 sham group (SG) to perform intervention and measurement through pre- and post-design. Intervention was performed in LMG with grade III~IV on L3-5 of the lumbar spine, and lumbar mobilization was performed for each segment. After intervention, knee flexion and extension strength were measured. To measure the main effect on muscle strength, a comparative analysis was conducted using paired t-test and independent t-test. Results: In LMG, knee flexor and extensor strength were increased significantly at 60°/s (P<.05). In addition, the extensors of LMG and SG were significantly different only at 60°/s, and the flexors were significantly different between groups at both 60°/s and 180°/s (P<.05). Conclusion: In healthy individuals, lumbar mobilization results in improvement of strength of knee flexor and extensor, and additional experiments on the effect of mobilization on the lumbar spine on functional changes in the lower limbs will be needed.

문제 정의
Thus, further studies are needed to clarify that joint mobilization can alter muscle activity. This study aimed to investigate the effects of lumbar mobilization on knee muscle activity in healthy individuals.
This study investigated the effect of postero-anterior lumbar mobilization on knee flexor and extensor strengths in healthy individuals. Knee flexor and extensor strength were statistically significantly improved according to the application of lumbar mobilization.
제안 방법
A two-group pretest and posttest design were accepted. According to treatment modality, the subjects were divided into two groups, a lumbar mobilization group (LMG) and a sham group (SG), by using simple random sampling. Intervention was performed through the pretest and posttest design (Figure 1).
Each isokinetic strength was measured repeatedly five times at 60°/s and 10 times at 180°/s, and the mean values were used. Four hours before the measurement, each participant was instructed to practice three times for improved adaptation to the test. In all the measurements, flexion strength was measured subsequently to extension strength, and a 1-minute break was provided between the measurements at each velocity.
In all the measurements, flexion strength was measured subsequently to extension strength, and a 1-minute break was provided between the measurements at each velocity. The participants were asked by the therapist to lean against the back of their chair at a constant force for the measurement of the maximum muscle strength in a natural way.
대상 데이터
Although 12 participants were allocated to each group at the beginning of the study, one participant in the LMG and two paricipant in the SG dropped out for personal reasons. Finally, the data of 21 participants were used in the analysis (Table 1).
The participants of this study were students at N University in Cheonan, Chungcheongnam-do, all of whom did not have lumbar pain or limited range of motion due to pain. Those who received surgery on the cervical spine in the last 6 months, were currently receiving lumbar treatment, or exercised more than three times a week, history of underlying disease or damage to the musculoskeletal system within the last year or less, such as knee or hip joint, lower extremity were excluded from the study.
데이터처리
Data normality was determined using the Kolmogorov-Smirnov test. A paired t-test was applied to identify the difference in strength between before and after the intervention in both groups. The change in strength was compared between the two groups through an independent t-test.

이론/모형
The general characteristics of the participants are presented using descriptive statistics. Data normality was determined using the Kolmogorov-Smirnov test. A paired t-test was applied to identify the difference in strength between before and after the intervention in both groups.
성능/효과
As a result of this study, significant increases in the strengths of the knee extensor and flexor muscles at 60°/s were observed in the LMG. In addition, statistically significant differences in the extensor strengths at 60°/s and 180°/s and flexor strength at 180°/s were found between the LMG and SG.
후속연구
Accordingly, by using joint mobilization, physical therapists can perform diagnosis by correlating the examination results with the characteristics and distribution of symptoms and choose the proper treatment based on the diagnosis. In this study, the effects of joint mobilization at the L3–L5 segments on the changes in the knee joint were investigated in healthy adults, the results of which can be used for future diagnosis and intervention.
8 reported that joint mobilization in patients with lumbar pain resulted in the improvement of knee extensor strength. Thus, further studies are needed to clarify that joint mobilization can alter muscle activity. This study aimed to investigate the effects of lumbar mobilization on knee muscle activity in healthy individuals.
