The hidden dangers of jump landings: How is the LESS scoring system changing sports medicine?
With the rise of sports activities and the popularity of various sports, the problem of sports injuries has attracted more and more attention. Among them, an effective sports assessment tool can help sports medicine professionals prevent injuries and improve sports performance. This makes LESS (Landing Error Scoring System) particularly important.
The importance of exercise assessment
Movement assessment is the practice of analyzing movement performance during functional tasks with the goal of determining the kinematics of individual joints and their impact on the kinetic chain. A deeper understanding of the biomechanics of sport, whether assessed in three or two dimensions, can help prevent injuries and improve performance. By identifying abnormal movement mechanics, physical therapists and athletic coaches can develop more precise corrective exercise programs to reduce the risk of injury and allow for effective rehabilitation and progression after injury.
A good joint motion examination not only helps the physical therapist diagnose a patient's functional loss, but also provides objective criteria to evaluate the effectiveness of treatment procedures.
LESS: A transformative tool
LESS is a valid and reliable biomechanical assessment tool for the assessment of jump landing skills. This scoring system covers 22 biomechanical criteria and focuses on lower limb and trunk performance, with results related to the risk of anterior cruciate ligament (ACL) and patellofemoral joint injuries. LESS scores are divided into the following categories: excellent (0-3); good (4-5); moderate (6-7); and poor (>7).
By identifying biomechanical abnormalities in landing technique, the effects of fatigue, and differences between genders, patients can receive more precise clinical movement interventions, thereby reducing the risk of injury.
Functional motion detection (FMS) and its role
The primary purpose of the FMS test, designed in 2006 by Gray Cook, Lee Bourton, and Barbara Hoogenboom, is the early detection of pathology or dysfunction in a specific group or individual. This test is designed to identify certain abnormalities in the motor system and is considered an assessment of an individual's functional status rather than a purely exploratory examination.
The FMS is a practical tool that enables professionals to assess fundamental fundamental movement patterns and consists of 7 different tests with scores ranging from 0 to 3.
The key to maintaining balance: the Romberg test
The Romberg test evaluates static balance, which involves standing with your feet together, arms at your side, and eyes closed. In this test, the ability to maintain posture without losing balance is assessed. This test is very helpful for older adults or anyone recovering from any type of injury.
Checking tool for spinal health: Adams test
The Adams test looks at a person's spine from different angles to detect possible deviations or misalignments. This test is particularly useful for detecting scoliosis and other spinal conditions. When performing, keep your feet hip-width apart, knees straight, and stretch forward with flexibility.
The relationship between single-leg squats and exercise
The single-leg squat is a functional test developed by Liebenson to examine the biomechanics of the lower limbs and provide mechanical indicators of performance in daily functional tasks. This test requires the tester to stand on the limb being tested and complete a squat with the knee joint flexed to at least 60° within 6 seconds.
The practicality of single-leg jumping
The single-leg hop test is widely used to evaluate the functional performance of the knee joint, particularly after an anterior cruciate ligament injury or reconstruction. Common jumping tests include distance single-leg jump, cross jump, triple jump, 6-meter timed jump, etc.
Normal return to sports standards mean that the injured limb should reach more than 90% of the uninjured limb.
The popularization and promotion of the LESS scoring system has brought a new perspective and application to sports medicine. It not only improves the efficiency of sports protection, but also brings new opportunities for sports rehabilitation. In the process of this change, we should think about what methods can be used to further improve the accuracy and effectiveness of sports assessment in the future?
