size / enrollment: 30

study description: Thirty children were asessed by physical therapist. Nineteen children was Level 1 and eleven children was Level 2 according to Brooke Lower Extremity Functional Classification Scale.

primary outcomes:

  • 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 outcomes:

  • 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.
