Sural Nerve Amplitude
Lasso di tempo: Baseline, 12, and 24 weeks
|
Maximal responses were obtained using percutaneous electrical stimuli.
Sensory nerve action potentials were recorded from sural (antidromic), median (antidromic to second digit), and ulnar nerves (antidromic to fifth digit).To minimize inter-examiner variability and maximize neurophysiologic test/retest reliability, the same experienced neurologist conducted all nerve conduction studies on days separate from all other testing activities.
A dedicated TECA Synergy electromyograph system was used for all nerve conduction studies.
The patients dominant side was chosen.
In patients with definable differences between the two sides, the side with the most prominent clinical findings was chosen.
In all cases, the same limb was used for all three (baseline, 12-weeks, 24-weeks) conduction studies.

Symptom-Limited TMT Blood Glucose Response
Lasso di tempo: Initial entry into study, 12 and 24 weeks
|
Changes in blood glucose in response to modified Bruce Protocol treadmill test (TMT)
|
Initial entry into study, 12 and 24 weeks

Short Form-36V: Physical Component Score
Lasso di tempo: Initial entry into study, 12 and 24 weeks
|
The short form-36Veterans (SF-36V) health survey questionnaire was used to measure health-related quality of life.
This survey is comprised of eight subscales and two overall component scores, all of which have demonstrated high levels of internal consistency and discriminate validity when administered to groups of medically stable individuals.
Patient aggregate responses for the eight distinct summary subscales and two component scores were compiled as a percentage of total points possible using the RAND 36-item health survey table.
Data shown are expressed as a percentage of total possible score ranging from 0%-100% with 100% considered relatively good health and 0% considered poor health.
Physical Component scores reflect perceived changes in physical health relative to the previous year.

Symptom-Limited TMT Maximum Carbon Dioxide Expelled (VCO2)

Symptom-Limited TMT Maximum METS Achieved (MET)
Lasso di tempo: Baseline, 12-wks, 24-wks
|
Peak metabolic rate equivalents (METS) achieved while undergoing a modified Bruce Protocol treadmill test (TMT).
One MET is defined as the metabolic rate observed at rest, quantified as resting oxygen consumption of 250 ml/min (Male) or 200 ml /min (female).
A value of 5 METS would represent a metabolic rate that is 5x that at rest and is considered an indicator of how hard a given individual is exercising.
Data shown are expressed as a ratio at peak of exercise of oxygen consumed relative to normalized values for men or women at rest.

Short Form-36V: Mental Component Score
Lasso di tempo: initial entry into study, and at 12-wks and 24-wks
