Brief Summary:
The investigator investigated the effect of lower limb flexibility on functional performance of children with Duchenne Muscular Dystrophy.

Condition or disease
Duchenne Muscular Dystrophy Performance Flexibility

Detailed Description:
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, hip flexors, tensor fascia latae, and gastrocnemius muscles were evaluated in dominant lower limb. Popliteal angle test, hip flexor flexibility test, tensor fascia latae flexibility test and gastrocnemius flexibility test were used for flexibility asssessments. Functional performance was assessed with 6 Minute Walk Test (6 MWT) and Timed Performance Tests. The correlation between the flexibility of lower limb muscles' and performance tests were examined.

Official Title: Lower Limb Flexibility in Duchenne Muscular Dystrophy: Effects on Functional Performance
Actual Study Start Date : January 2017
Actual Primary Completion Date : June 2017
Actual Study Completion Date : December 2017

Primary Outcome Measures :
  1. 6 Minute Walk Test [ Time Frame: 6 Minute ]
    The 6 Minute Walk Test (6MWT) is a standard test recently used to evaluate functional capacity in neuromuscular diseases, and found to be a safe and valid test that can be performed in Duchenne Muscular Dystrophy

Secondary Outcome Measures :
  1. Timed Performance Test [ Time Frame: 3 minute ]
    Timed performance tests such as 10 m walk, Gower's (from supine position to stand up), ascending/descending 4 steps were also performed. During these tests, the child's performance was recorded in seconds.
