About this study

Children with Duchenne Muscular Dystrophy (DMD) have difficulties towards the end of the ambulatory period, especially in activities that require lower extremity proximal muscle strength such as walking, climbing stairs, standing up without sitting. Stair climbing / descending activity is a complex activity that requires joint stability, correct muscle synergy and timing. When the literature is examined; It has been observed that the performance of stair climb up and down activity in individuals with neuromuscular disease has been evaluated with various clinical applications. In recent studies, there are surface electromyography (EMG) studies evaluating various aspects of stair climbing and descending activity.

Surface EMG; is a technique for neuromuscular evaluations that is frequently used in both research and clinical applications, noninvasive, and can be used in areas such as neurophysiology, sports science and rehabilitation.

Our study was planned to examine the muscle activations in the lower limb muscles involved in climbing up stairs activity in children with DMD and to compare healthy children with children with DMD and children with different levels of DMD.

Hypothesis originating from the investigation:

H0: There is no difference in the muscle activations measured by surface electromyography (EMG) of the involved lower extremity muscles during climbing up stairs activity between level 1 and level 2-3 children with early DMD.

H1: There is a difference in the muscle activations measured by surface electromyography (EMG) of the involved lower extremity muscles during climbing up stairs activity between level 1 and level 2-3 children with early DMD.

H2: There is no difference in the muscle activations measured by surface electromyography (EMG) of the involved lower extremity muscles during climbing up stairs activity between children with DMD and healthy children.

H3: There is a difference in the muscle activations measured by surface electromyography (EMG) of the involved lower extremity muscles during climbing up stairs activity between children with DMD and healthy children.

Read the detailed description

In our study, children will be assessed using the surface Electromyography (EMG) device by using electrodes placed in the relevant lower limb muscles that take part during the stair climbing activity.

The study included 10 children with DMD levels were 1 and 10 children with DMD levels were 2-3 according to the Brooke Lower Limb Functional Classification scale and 10 healthy children.

Muscle activation of vastus lateralis, biceps femoris, tibialis anterior and gastrocnemius medialis muscles will be measured by superficial electromyographic measurement. Muscle activation according to SENIAM (surface EMG for a non-invasive assessment of muscles) for will be evaluated.

Stair climbing activity will be performed 3 times and at 1 minute intervals.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Electromyographic deviceOther

    An 8-channel surface EMG system (DELSYS Trigno Wireless System) will be used to measure signals from muscles during stair climbing activity by surface electromyography measurements.Surface EMG measurements will be carried out during stair climbing activity without any intervention in the body. Surface EMG electrodes will be placed bilaterally in the vastus lateralis, biceps femoris, tibialis anterior and gastrocnemius medialis muscles.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Surface Electromyographic Measurement

    Muscle Activation Measurement It is an 8-channel system for measuring signals come from muscles (Delsys)

    Measured: 40 minutes

Secondary outcomes (4)
  1. Muscle Strength Measurement

    A quantitative and objective method for assessment of muscular strength using a portable hand held dynamometer. Muscle strength measurement included lower limb and trunk muscles.

    Measured: 15 minutes

  2. Timed Performance Test

    Timed function tests included time taken to stand from a supine position, time taken to walk 10 m, time taken to climb 4 standard-sized stairs and time taken to descend 4 standard-sized stairs.

    Measured: 20 minutes

  3. Muscle shortness assessment

    Shortening assessment of trunk and lower extremity muscles measurement included back extensors, hamstring, hip flexors, quadriceps and gastrocnemius muscles.

    Measured: 10 minutes

  4. Six minute walk test

    Children were asked to walk during 6 minutes as fast as possible at a 25 meter corridor.

    Measured: 6 minutes
