Alternative Hypothesis: Electrical Stimulation is an effective way to reduce Neuropathic pain among diabetic patients (µ â‰ 0).
Method: The study selected 10 subjects (7 males), presented for evaluation of painful nocturnal diabetic neuropathy. Control and experimental groups were established, in accordance of course with accepted ethical principles.
Variables: The dependent variable in the study is the level of neuropathic pain (among patients with nocturnal diabetic neuropathy). The independent variable is the level or amount of pulsed-dose electrical stimulation projected to patients with nocturnal diabetic neuropathy.
Level of Significance: The study used Î± = 5% as the level of significance. A level of significance equal to 5% is acceptable because it ensures both the reliability and validity of the results.
Outcome: The results of the study suggests that nocturnal doses of pulsed electrical stimulation may be effective in alleviating subjective neuropathic pain in a population consisting of patients with grossly intact protective sensation, relatively good vascular perfusion, and less than ideal glucose control.
Comments: The number of selections should be > 25, in accordance with the Central Limit Theorem (Garcia, 2004). It may also be better for the authors to consider other variables, as medical conditions are usually explained by a consortium of related variables.
