The Reliability and Validity of the L-test in Patients With Multiple Sclerosis
Condition: Multiple Sclerosis
MeSH terms: Multiple Sclerosis; Sclerosis
Study type: Observational

Summary: 
      Walking safely inside or outside is an important function in patients with Multiple Sclerosis
      (PwMS) that affects their daily life activity and participation. Loss of functional mobility
      is the major component of walking disorders in PwMS. Therefore, it is important to evaluate
      functional mobility.

      Many functional mobility tests have been used for PwMS; however, these tests generally focus
      on walking speed and endurance. On the other hand, the L test, a variation of the timed up
      and go test (TUG), is a functional mobility measurement tool that extends the total walking
      distance to 20 meters and also requires the patients to turn both clockwise and
      counterclockwise.

      Although L the test is an easy-to-use, short-term test method that evaluates higher-level
      components of functional mobility such as turns and transfers, to our knowledge, no study has
      systematically examined the reliability and validity of the L test in PwMS yet. In addition,
      the cut-off times that best discriminate PwMS from healthy people and fallers with
      non-fallers with Multiple Sclerosis (MS) have not been reported. Therefore, this study
      planned to investigate the reliability, validity, and discrimination of the L test in PwMS.
    

Detailed description: 
      At baseline, the L test, Timed Up and Go test, 10 meter walk test, six minute walk test, and
      the timed 360 turn test will be applied to the Multiple Sclerosis group. The L test will be
      repeated after seven days after the first application in PwMS. Healthy controls are going to
      perform only the L test.

Intervention type(s): Other; Other; Other; Other; Other
Intervention description(s): The test includes standing up from a chair, walking in a straight line for 3 m, turning to the right, walking in a straight line for 7 m, turning around, walking back 7 m along the same line, turning to the left, walk 3 m in a straight line to the chair, and then sit down.; The test requires the individual to stand up from an armed chair, walk 3m, turn around, walk back to the armed chair, and sit down again.; In the test, the clinician measures the time taken to walk a distance of 10 m from a standing position. Participants are asked to walk along a 14 m long walkway.; This test measures the distance (in m) that an individual is able to walk at a comfortable speed for 6 minutes. Starting from a standing position, participants walk continuously around two pylons placed 30 m apart for 6 minutes. The distance is recorded end of the test.; Each participant turns around in place in a standing position for both sides.
