New Triple Hop Test Quality Assessment Tool

Study Overview
=================
Brief Summary
-----------------
This study will develop a new jump assessment tool for the Triple Hop Test, and will test its reliability on adolescent and adult, healthy and post- anterior cruciate ligament (ACL) population. Creating a new assessment test for a jump test that incorporates the known movement components that are important after an ACL injury can improve patient evaluation, decision for return to sport activity and injury prevention.

Detailed Description
-----------------
Study population- Adults, women and men aged 20-45, boys and girls aged 12-15. uninjured population: non symptomatic subjects, without major injury in their history. Injured population: ACL injured subjects, 9-12 month after beginning of treatment/surgery. Stages of study: stage 1- The investigators will create a new high-quality literature-based assessment test for the triple hop test (NTHT). The test will have 10 sections, its score ranges from 0 to 14 points and a high score means poor performance. Stage 2- Performing reliability tests between and within the testers for NTHT. The tests will be done with the help of video photography of NTHT. Stage 3- Performing NTHT and THT tests on healthy adult and adolescent subjects and on ACL adult and adolescent subjects, assessing the NTHT by watching video performance.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Healthy adult<br>Each participants will be asked to perform triple hop test on a straight line and to stand stable at the end of the jump. Two jumps will be performed on each leg, with 1 minute rest between them. The jumps will be recorded via video. Legs muscle strength will be assessed using hand held dynamometer | Other: new triple hop test<br>* New jumping assessment will be performed in all included study groups. This new assessment includes quality evaluation.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| New triple hop test score | the score ranges between 0-14. lower score represent better jumping quality. | baseline | 
| triple hop test | measurement of jumping distance(in cm) and symmetry between legs | baseline | 
| muscle strength | muscle strength in Newton, assessed by an hand held dynamometer. | baseline |
