Transcranial direct current stimulation (TDCS) on the brain was used in attempt to find a way to allow stroke patients to recover their motor skills. Strokes are the leading cause of motor impairments in people. A stroke is caused by an interruption of blood supply to the brain. Depending on which part of the brain was affected their motor skills range in severity. Someone who had a stroke would have to go to physical therapy to regain the motor skills that they had before. Though everyone is different, on average a person would be limited for 8 years or more before they can regain their motor efficiency. TDCS would increase the synaptic plasticity, meaning it changes how the neurons are excited. The neurons would have a lower threshold, meaning that it would require less excitatory signals to send a signal. Which would allow the stroke patients to use less effort compared to a healthy human to send a signal for movement. When comparing stroke patients who went through TDCS and patients who did not, it was found that TDCS did not work as planned. The results showed that the retention of motor skills between the use of TDCS and not were equal. Memory of how to do the motor skill were not remembered, just like patients that did go through TDCS. Therefore, TDCS did not improve anything and would be unnecessary as a treatment for stroke patients.

Suggestion
I would just fix the structure of the introductory sentence, "Transcranial direct current stimulation (TDCS) on the brain was used in attempt to find a way to allow stroke patients to recover their motor skills." to something that flows a bit easier such "Transcranial direct current stimulation (TDCS) was a technique tested on the brain as a means of allowing stroke patients to recover lost motor skills."
Suggestion
The fourth sentence "Depending on which part of the brain..." is worded rather confusingly. I would suggest changing it to something like "The part of the brain that is affected determines the severity of the impact on the person's motor skills".
Feedback
At the end of your paragraph, you refute topic sentence and the subject of your paragraph. As such, I think you should change your title because it is misleading.
