Outcome Measures

Primary Outcomes (2)

  • Value of the Peripheral Neuropathy Total Symptom Score (TSS) Compared to Baseline

    The TSS of peripheral neuropathy is used to score the intensity \& frequency of four symptoms in participants' feet/legs including: pain, burning sensation, numbness, and hypoesthesia. Frequency is ranked as asymptomatic, occasionally (2-3 times/ week), often (1-2 times/ day), \& continuous (nearly all day). Intensity is evaluated by visual analogue scale (VAS) score: 0 (zero intensity)- 10 (max. intensity). Participants described intensity by marking the number corresponding to severity of symptom they felt in a 10 cm long straight line and investigators distinguished whether it was mild (score: 1-3), moderate (score: 4-6), or severe (score: 7-10). The total score of four symptoms was considered the TSS. Total scores ranged from 0-14.64 points, where 0 was lowest symptom score and 14.64 was most severe level of symptoms. Baseline (before treatment) scores were compared to scores after 4 weeks of treatment.

    Baseline & End of Week 4

  • Rate of the Peripheral Neuropathy Total Symptom Score (TSS) Compared to Baseline

    TSS of peripheral neuropathy is used to score the intensity \& frequency of 4 symptoms in participants' feet/legs including: pain, burning sensation, numbness, hypoesthesia. Frequency is ranked as asymptomatic, occasionally (2-3 times/ week), often (1-2 times/ day), \& continuous (nearly all day). Intensity is evaluated by visual analogue scale (VAS) score: 0 (zero intensity)- 10 (max. intensity). Participants described intensity by marking the number corresponding to severity of symptom they felt in a 10 cm long straight line and investigators distinguished whether it was mild (score: 1-3), moderate (score: 4-6), or severe (score: 7-10). The total score of four symptoms was considered the TSS. Total scores ranged from 0-14.64 points, where 0 was lowest symptom score and 14.64 was most severe level of symptoms. Baseline scores were compared to TSS decreasing rate after 4 weeks of treatment. Rate of TSS change = (TSS difference value/TSS before treatment)Ă—100%.
