Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

It is known that low back injuries experienced by weightlifting athletes cause a decrease in performance. The effects of spinal manipulative therapy, which has been found to positively affect performance in various sports, are not known in the Olympic style weightlifting athletes. This study is aimed to investigate the effects of lumbosacral chiropractic spinal manipulative therapy on muscle strength, range of motion, balance, and pain in Olympic style weightlifting athletes.

In this research, 40 male Olympic style weightlifting athletes are planned to take place. Male athletes will be randomly divided into two groups as a control and a treatment group. To the individuals in the treatment group; lumbal region chiropractic high-speed, low amplitude (High Velocity, Low amplitude: HVLA) spinal manipulation and sacroiliac joint chiropractic HVLA manipulation are planned to perform once a week for a total of three weeks. No manipulation will be made to individuals in the treatment group. Before and after the manipulation; the maximum isometric muscular force, the lumbar spine range of motion, balance performance and pain intensity will be evaluated by a back dynamometer, hand finger-ground distance test (HFGD), and Modified Schober test, flamingo balance test, and visual analog scale. SPPS 25 (IBM Corp. Released 2017. IBM SPSS Statistics for Windows, Version 25.0. Armonk, NY: IBM Corp.) version will be used to analyze the data.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

There are studies in the literature regarding the positive effect of chiropractic treatment on musculoskeletal injuries. In a study, it is found that the group that received cervical chiropractic manipulation on judo athletes showed a statistically significant (p \<0.05) increase in grip strength compared to those who received sham practice. In another study, it is found that a single lumbar spinal manipulation reduced the relative strength difference between the limbs for knee and hip flexion (p \<0.05). In another study, it is shown that a single spinal manipulation session increased the muscle strength of the ankle plantar flexor muscles and corticospinal excitability (p \<0.05) in elite Taekwondo athletes. Likewise, according to another study, lumbopelvic joint manipulation increased quadriceps activation and strength.

A study claims that young female athletes with talocrural joint dysfunction showed a statistically significant (p \<0.05) improvement in vertical jump height after chiropractic manipulation. In addition, in a study investigating the effect of pelvic manipulation on vertical jump height in female university students with functional leg length inequality, it was found that after the intervention, jump height improved significantly only in the pelvic manipulation group compared to pre-intervention height, while improvement in female university students with functional leg length inequality was found to be statistically significant (p \<0.05) in both manipulation and stretching groups after the manipulation.

A study showed that chiropractic spinal manipulative therapy can increase hip extension ability in young running athletes (p \<0.05). According to a study conducted on football players, it was shown that combined manipulative interventions caused significantly (p \<0.05) increases in the range of motion in the lumbar region and sacroiliac joint flexion. In addition, it was reported that the group who received chiropractic manipulation (compared to the group that received sham manipulation) caused a significant increase in kick speed (p \<0.05) after the manipulation.

Again, in another research, it is found that an increase in cervical range of motion and a decrease in neck pain with a single cervical HVLA (High Velocity, Low amplitude: HVLA) manipulation (p \<0.05) and stated that HVLA manipulation was more effective than mobilization.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control group

20 people will be included in the control group. 3 measurements will be taken one week apart in total. Measurements will consist of maximum isometric muscle strength, lumbar range of motion, balance performance, and pain intensity. And it will be evaluated respectively by back dynamometer, hand finger-to-ground distance (HFGD) and Modified Schober test, flamingo balance test, and visual analog scale.

Group Type NO_INTERVENTION

No interventions assigned to this group

Chiropractic group

20 people will be included in the experimental group. Lumbal chiropractic HVLA (High Velocity, Low amplitude: HVLA) spinal manipulation and sacroiliac joint chiropractic HVLA manipulation will be applied 3 times in total with a weekly interval. The maximum isometric muscle strength before and immediately after the application, lumbar joint range of motion, balance performance, and pain intensity will be evaluated respectively by back dynamometer, hand finger-to-ground distance (HFGD), and Modified Schober test, flamingo balance test, and visual analog scale.

Group Type EXPERIMENTAL

Chiropractic Manipulation

Intervention Type OTHER

Lumbar vertebrae and sacroiliac joints of the participants that have lost their normal joint motion will be detected by static and dynamic palpation techniques.

Lumbal Chiropractic HVLA Spinal Manipulation: HVLA manipulation will be applied in the left transverse process of the lumbar vertebra (mammillary process) of the participants whose problem is to the left of the lumbar vertebra.

Sacroiliac Chiropractic HVLA Manipulation: Participants who lost normal joint motion in the anterior and superior directions in the left sacroiliac joint will be treated with HVLA manipulation in the left PSIS (Posterior Superior Iliac Spine: PSIS). Participants who have lost normal joint motion in the left sacroiliac joint in the posterior and inferior directions will be applied HVLA manipulation in the left ischial tuberosity.

For both applications, it will be positioned in the opposite position for the problems on the right and the application will be made in the opposite position.
