Official Title: Effect of Trunk and Lower Extremity Muscle Strength on Hamstring Flexibility in Children With Duchenne Muscular Dystrophy
Actual Study Start Date : March 24, 2017
Actual Primary Completion Date : September 25, 2017
Actual Study Completion Date : January 1, 2018

Primary Outcome Measures :
  1. popliteal angle test [ Time Frame: 5 minute ]
    The popliteal angle test was performed to assess hamstring flexibility. The popliteal angle was measured in a supine position and the hip flexed 90°, and fixed by first physical therapist. Opposite knee and hip were placed in extension position. Then, the child was asked to rise lower leg straight. The incomplete angle for full extension of the knee was the popliteal angle.

Secondary Outcome Measures :
  1. trunk and lower extremity muscle strength test [ Time Frame: 20 minute ]
    Trunk and lower extremity muscle strength was assessed manual muscle strength and myometer. Any test was performed three times and best value was recorded.

Study Population
Thirty children whose functional levels were in 1 or 2 according to the Brooke Lower Extremity Functional Classification Scale were included in the study. Flexibilities of hamstrings was evaluated by Popliteal Angle Test. Muscle strenght was assessed with manuel muscle strength test and myometer. correlation between the flexibility of hamstrings and muscle strength tests were examined.
