“…19 For these reasons, the SDNN values reported in this paper cannot be used for medical diagnosis, especially where consistent normative values have not been well established. 20 Fatigue was assessed using a psychometric scale called the Iowa Fatigue Scale (IFS), 21 as well as an electrophysiological measure of eye blink rate duration. 22 The IFS was used to measure self-reported fatigue and is composed of 11 Likert items covering 4 subscales: cognitive, fatigue, energy and productivity.…”

“…22 The IFS was used to measure self-reported fatigue and is composed of 11 Likert items covering 4 subscales: cognitive, fatigue, energy and productivity. 21 The purpose of using the IFS was to determine the impact of a SCI on subjective fatigue levels, as well as determine whether associations exist between fatigue and HRV. To complete the IFS, participants were rated on a five-point scale of 1 'not at all' to 5 'extremely' to each item--for example, 'I feel worn out' and 'I have trouble concentrating.'…”

“…An IFS total score of around 30 or higher indicates severe fatigue. 21 Fatigue was also assessed by eye blink duration, provided by EOG, which has been shown to provide a sensitive physiological measure of fatigue. 6,22,23 Eye blink duration was counted and measured from the unfiltered EOG raw signal at 500 mV in 2-s intervals on a low-pass filter.…”

Study design: Group cohort design. Objectives: To determine the influence of spinal cord injury (SCI) and neurological level on heart rate variability (HRV) and associations with fatigue. Setting: SCI rehabilitation outpatient and community settings in New South Wales, Australia. Methods: Participants included 45 adults with SCI living in the community and 44 able-bodied controls. Socio-demographic, neurological injury, psychological, HRV and eye blink variables were assessed. Multivariate analysis of variance and post hoc protected t-tests were used to determine differences in HRV and fatigue as a function of the neurological level. Pearson's correlation analysis was used to determine the relationships between these factors. Results: Participants with SCI had significantly reduced sympathetic activity. Those with tetraplegia had lowered sympathetic activity compared with those with paraplegia and able-bodied controls. Neither were differences in parasympathetic activity found between groups nor were there any significant differences found for the time domain or non-linear domains. Higher levels of fatigue were found in the SCI sample, and participants with tetraplegia had higher fatigue levels compared with those with paraplegia. Fatigued participants were more likely to have altered autonomic function--that is, reduced sympathetic activity. Conclusions: Higher levels of neurological impairment in people with SCI are more likely to result in disordered cardiovascular control involving reduced sympathetic activity, whereas elevated fatigue was found to be associated with increased sympathetic dysfunction. Findings highlight the need to address risks associated with this dysfunction, such as improved HRV and fatigue screening for people with SCI and improved education on cardiovascular risk factors.

Background: Hemodialysis is a physically stressful procedure and most of the patients will have fatigue and thereby an alteration in the electrolytes, hemoglobin level. Physical Exercises provided during Hemodialysis session do not cost patients extra time and will be effective in reducing fatigue level and enhancing potential for performing their activities of daily living & may increase the waste removal. Objective: This study was conducted to determine the impact of an eight-week Intradialytic Range of Motion Exercise program (consisting of 15 minutes low-intensity exercise during the first 2 hours of Hemodialysis) on Fatigue, electrolytes levels, Hemoglobin and Blood pressure. Methods: A randomized controlled pre test post test design was utilized in this study in a hemodialysis unit, a total of 30 hemodialysis patients were enrolled into the study and randomly allocated into two groups. The experimental (The exercise group) (n = 18) and the control group (n = 12). Range of Motion Exercises were done in the experimental group for 15 min/day, three times a week for 2 months. Fatigue was measured via a Iowa Fatigue Scale (IFS) and Physiologic Parameters Form to measure serum electrolyte level, hemoglobin and blood pressure pre and post as well as at the end of each month after the intervention in both groups. Results: After an 8-week of Intradialytic Range of Motion Exercises program, a significant reduction were seen in fatigue level, serum phosphate and potassium, calcium, urea, creatinine and a slight increase in hemoglobin level. Systolic and diastolic blood pressure changed significantly in the exercise group (p < .05). Conclusions: A simplified physical exercise program may be considered as a safe, and effective clinical nursing modality in patients with end-stage renal disease on Hemodialysis.
