Electrical Stimulation and Muscular Dystrophy

Blog #2 - Week 5

For my final blog, I have decided to discuss e-stim and the potential benefits for muscular dystrophy patients.  On a personal note, I have been interested in electrical stimulation ever since I was a young child. I remember reading articles about various Russian athletes using electro-stimulation to increase strength and performance. It was not until joining the PTA program, however, that I understood the many different types of e-stim. They all produce an electrical stimulation, but the current and values of each vary and are used for different methods of treatment (i.e. reducing pain, muscle contraction, etc.)

The study I researched involved nine children affected with either Duchenne or Becker muscular dystrophy. They underwent a low-frequency electrical regimen with stimulation directed toward their right anterior tibialis muscle. The goal of the treatment was to measure changes in dorsiflexion of the stimulated right leg compared to the non stimulated left leg.

Four of the boys were stimulated and measured for a three-month period.  No changes resulted from the treatment. The five remaining boys underwent treatment for nine months and did show some improvement in right ankle torque / dorsiflexion compared to their left leg. According to the article, “6 measurements made during the stimulation program revealed that changes of torques in the ankle of the right stimulated extremity were significantly different from the changes of torques in the ankle of the left nonstimulated extremity.”

It appears electrical stimulation can offer some benefit to patients with muscular dystrophy, but only if sustained over a long period of time.
