• Conditions: Anterior Cruciate Ligament Rupture

• Registration Number: NCT06831279
• Lead Sponsor: Marmara University

Brief Summary

The anterior cruciate ligament is incumbent upon the stabilization of the knee joint in our body. Consequently, it is also of great importance for athletes since it is seen that injuries in clinics are predominantly monitored in young individuals, who do active sports. Anterior cruciate ligament injuries commonly occur in football players when a secondary task (motor or cognitive) is involved while they are busy with a motor activity. In these processes, a circumstance, in which there becomes a quick landing after a jump or a difficult pass whilst dribbling the ball, can be monitored. In such cases, the subject of preventing these injuries, which may occur in athletes, and making them ready for second tasks after the treatment of the injury, has become a current issue. It is important for individuals who have suffered the injury- to be able to bring the knee joint to its former function at the highest level after anterior cruciate ligament reconstruction. As a result, the development of novel rehabilitation strategies has been an ongoing focus of research. A prime exemplar of this phenomenon is the implementation of dual-task exercises. Dual-task exercises appear in athletes as motor-cognitive or motor-motor. Athletes' exercising motor-cognitive functions has attracted the attention of researchers in the past period to prevent injuries in sports and has brought a new breath to the academic world. Studies suggest a decrease in cognitive and motor functions in the acute period after injuries. However, observing its long-term effects, they also suggest an increase in the attention parameter, crucial for athletes.

In a study examining postural stability in individuals, who underwent an operation of anterior cruciate ligament reconstruction by giving motor-motor or motor-cognitive exercises, it is seen that worse results are obtained in postural stability in individuals, who underwent only anterior cruciate ligament reconstruction compared to healthy individuals. Furthermore, in cases -in which eyes were closed and dual motor tasks were given-, more negative results are obtained compared to the open-eyed group. It is associated with a significant decrease in proprioceptive performance in individuals after anterior cruciate ligament injury. Owing to this decrease, postural control decreases, and negative situations arise due to the pathology of the individual. The star balance test is a sensitive test to determine and emerges as an exercise that will correct this negative situation. Post-ACL injury, individuals exhibit significantly lower physical component scores in quality-of-life assessments compared to healthy controls, as reported in books and articles. Moreover, after the ACL reconstruction, a decrease in the mental scores of the individual is seen owing to reasons such as long-term absenteeism from work, rehabilitation, the high costs of the operation, and traumatic occasions.

Foam roller, one of the current treatment modalities, is a myofascial release technique. The purpose of the foam roller application is to activate myofascial release by using the athlete's body weight and back-and-forth movement cycle. It has been observed that the usage of foam roller delays the emergence of delayed muscle soreness with myofascial release in the quadriceps and hamstring muscles, while also increasing joint range of motion. Despite the widespread utilization of foam rollers in clinical practice, empirical evidence elucidating the underlying mechanisms and clinical efficacy of this modality remains relatively limited. Nevertheless, the factors -which are consequential in the return to pre-injury performance of the athletes- have not been thoroughly scrutinized. For instance, there is no encounter in the literature examining the effects of dual-task exercises on kinesiophobia, ACL-specific quality of life, star balance test evaluation, normal range of motion evaluation, Tegner-Lysholm knee scoring scale.

The purpose of the study is to compare two different rehabilitation groups in terms of pain, range of motion, functionality, balance, quality of life, and kinesiophobia in individuals who underwent ACL reconstruction. The first group is the one with a dual-task approach given during walking and balance exercises together with the conventional physiotherapy program. The latter is the one with the same dual-task approach given during walking and balance exercises together, as an extra with a foam roller.

Primary Outcome Measures

Name	Time	Method
Star Excursion Balance Test	Eight week later	Dynamic balance was measured using the Yıldız Balance Test (YBT). Athletes will reach with their feet to the directions of a star drawn on the ground with a 45° angle, resulting in a total of 8 directions. The distance they can reach will be recorded in centimeters.; Prior to the test, athletes will be given 3 minutes to familiarize themselves with the test, and there will be a 2-minute rest between trials. Additionally, a 5-second period will be allowed for the athletes to stand on both feet between each reach. The balance score is calculated using the formula "distance/leg length x 100" (Sitti S., 2013). If a volunteer cannot maintain balance on one foot, falls, pulls their hands away from their waist, or feels pain, the test is terminated.

Secondary Outcome Measures

Name	Time	Method
Quality of Life Assessment: (ACL-QOL Questionnaire)	Eight week later	ACL-QOL is the only valid and reliable scale that measures the quality of life from the patient's perspective, rather than clinical criteria specific to ACL injuries, and it is available in Turkish. (Kinikli GI., 2015). This test examines 5 main areas with a total of 31 questions: symptoms and physical complaints (4 questions), work-related concerns (4 questions), hobbies, sports, or participation in competitions (12 questions), lifestyle (6 questions), and social and emotional aspects (5 questions).
Tegner and Lysholm Rating Systems	Eight week later	The Lysholm score was first investigated and developed in the 1970s. The Lysholm rating system is a 100-point scale consisting of 8 different items, with questions specifically related to instability and pain. It has been validated and is reliable in Turkish. (Çelik D., 2013). The Tegner activity score is a system with a scoring range of 0-10, including questions about daily life and sports activities. (Briggs KK., 2006).
Range of Motion	Eight week later	The normal range of motion for the knee joint is measured by moving the joint from the starting position of a typical universal goniometer to the end position of the entire range of motion, and recording the number indicated on the goniometer. In this study, a universal goniometer will be used to measure knee joint range of motion for both flexion and extension.
Pain Scale	Eight week later	Visual Analog Scales (VAS) are psychometric measurement tools that make it possible to quantify the intensity of a symptom as subjectively experienced by individuals. (Klimek, 2017). For pain assessment, a 100 mm paper is provided. One end of the paper is labeled 'no pain - 0' and the other end is labeled 'worst possible pain - 100'. The patient should mark the line according to their condition at the time of the assessment. (Myles et al., 2017). The point where the mark is placed is noted and recorded.
Tampa Scale for Kinesiophobia (TSK):	At the baseline	Kinesiophobia (fear of movement) was first introduced in 1990 and will be assessed using the Tampa Scale for Kinesiophobia (TSK). (Miller et al., 1991). The TSK is a questionnaire consisting of 17 items designed to assess the fear of re-injury due to a previous trauma. The primary questions address variables related to re-injury, fear, and avoidance of movement in relation to the person's occupation or activities. The TSK uses a Likert scale with 1, 2, 3, and 4 points (1: Strongly Disagree, 4: Strongly Agree). Scores range from 17 to 68. (Huang et al., 2019). A higher score on the scale indicates a higher level of fear of movement. (Demirbuken et al., 2016).
