Background
Recently, transcranial direct current stimulation (tDCS), a noninvasive brain stimulation technique, was proposed as a suitable method for the treatment of several chronic pain syndromes. We describe a case of severe heel pain in a diabetic patient with plantar fasciitis successfully treated with tDCS.
Methods
The present study investigated whether tDCS treatment could reduce pain and pain-related anxiety in a 65-year-old diabetic man affected by treatment-resistant right heel pain due to plantar fasciitis. The patient underwent five tDCS treatment sessions on 5 consecutive days. Each session consisted of 20-min anodal tDCS over the left primary motor cortex leg area.
Results
The neurostimulation protocol induced a decrease in pain intensity and pain-related anxiety that outlasted the stimulation (1 week). Furthermore, the patient stopped the intake of opioid medication.
Conclusions
Therapeutic neuromodulation with tDCS may represent an alternative option for treating severe lower-extremity pain.
Background
A cross-sectional survey administered to first- and second-year podiatric medical students aimed to investigate the effect of coffee intake, energy drink consumption, and perceived stress on sleep quality in medical students during their preclinical studies.
Methods
Ninety-eight of 183 students contacted (53.6%) completed a questionnaire comprising standard instruments measuring sleep quality (Pittsburgh Sleep Quality Index), daytime sleepiness (Epworth Sleepiness scale), and perceived stress (ten-item Perceived Stress Scale). Furthermore, we investigated coffee and energy drink consumption. Logistic regression was conducted to identify factors associated with poor sleep quality and the relation between sleep quality and academic performance (grade point average).
Results
High prevalences of poor sleep quality, excessive daytime sleepiness, and perceived stress were reported. In addition, higher odds of developing poor sleep quality were associated with coffee and energy drink intake, perceived stress, and excessive daytime sleepiness. The total Pittsburgh Sleep Quality Index score was inversely correlated with grade point average.
Conclusions
First- and second-year podiatric medical students have poor sleep quality. Further research is needed to identify effective strategies to reduce stress and decrease coffee and energy drink intake to minimize their negative effect on sleep quality and academic performance in podiatric medical students.
Background:
The present study aimed to investigate the correlation between abductor hallucis (AH) muscle motor evoked potential (MEP) amplitude and foot arch anatomy.
Methods:
Twelve healthy individuals underwent foot arch measurement using a digital photographic technique and measurements of cortical excitability using transcranial magnetic stimulation applied on the cortical representation area of the right AH muscle. Truncated foot length and dorsal height were then measured and used to create the arch height index (AHI). Resting motor threshold, MEP amplitude (using a stimulation intensity of 110% resting motor threshold), and cortical silent period duration were also measured.
Results:
Mean ± SE values were as follows: truncated foot length, 16.72 ± 0.3 cm; dorsal height, 5.62 ± 0.13 cm; AHI, 0.34 ± 0.01; resting motor threshold, 81.6% ± 2.12%; MEP amplitude, 0.71 ± 0.1 mV; and cortical silent period duration, 108.05 ± 0.45 msec. A significant correlation was found between MEP amplitude and AHI (Spearman's rho: P < .01).
Conclusions:
These results indicate that AH muscle functional neuroanatomy measurements are reliable and might be used by clinicians and therapists to investigate foot arch physiology and monitor the efficacy of treatments and rehabilitative protocols.
