Pain management practitioners must meet the standards of care to avoid selleck chemical liability for

malpractice.3 As a result, physicians look for more objective and quantitative data than patients’ pain complaint to estimate the severity of radiculopathy. There are some studies, which indicate that the two-point discrimination test is applicable for the assessment of various painful diseases associated with sensory-motor deficit.4-7 This study was designed to find out whether or not the changes in patients’ skin sensation, seen in lumbo-sacral disk root pain, correlate with their disease condition during conservative treatment. Materials and Methods The study was conducted observing the ethical guidelines Inhibitors,research,lifescience,medical approved by the Ethics Committee, Jundishapur University of Medical Sciences, Ahvaz, Iran. The objective of the study was explained to the participants, and written informed consents were obtained. This is a cross-sectional study recruiting 20 right-handed females, whose Inhibitors,research,lifescience,medical ages range was 40-58 years. Using

simple random sampling, they were recruited from three community-based facilities in a period from April 2006 to January 2009. The subjects were selected based on their medical histories and physical Inhibitors,research,lifescience,medical examinations. Since it was expected that the treatment plan would improve their conditions, all of the patients agreed to participate in the study. Inhibitors,research,lifescience,medical All of the patients were diagnosed with lumbo-sacral radiculopathy through the physical examination, and approved by para-clinical studies.1,2 They were hospitalized for a week of complete bed rest during the study. Furthermore, they received oral sodium diclofenac (Alborz Darou Co., Tehran, Iran); 25 mg four

times-a-day, and oral prednisolone (Aburaihan, Tehran, Iran); five mg once daily for five consecutive days.8,9 Skin sensitivities and touch thresholds of the L4, L5 and S1 dermatomes were measured and recorded by a BASELINE R plastic two-point Inhibitors,research,lifescience,medical discriminator instrument on the first day and on the seventh days of hospital admission. Based on segmental innervations, dermatomes with less innervations Olopatadine overlap were selected, and two-point discrimination tests were performed.10 The plastic pins typically minimize the influence of temperature on touch sensation. A minimal pressure of two pins was simultaneously applied while measuring the ability of each patient’s two-point discrimination test values. In order to have more reliable control measurements, the same measurement method was performed to the unaffected lower limbs by the same examiner. The straight leg raising test (SLR) was performed for all the subjects bilaterally in supine position, and the positive or negative results were recorded.11 Also, the patients’ pain was individually quantified using a Visual Analog Scale upon arrival and on the seventh day of hospitalization.
