Posture control using electrical stimulation biofeedback: a pilot study

Functional joint instability is common after joint soft tissue injuries. We present in this report our pilot finding in a study of functional ankle instability. Although past studies have suggested multiple pathological factors for functional ankle instability, none of those factors has been confirmed in the past studies. More importantly, no known factor can provide an explanation for an ankle giving way phenomenon which is a key element in defining a functional ankle instability. In this pilot study, we tested five subjects with functional ankle instability using a dynamic ankle stretching device combined with nociceptive electrical stimulation. Three out of five subjects showed a drastic reaction in which they totally gave up their control of upright standing after their affected ankles were under the combined ankle stretch and nociceptive stimuli. Such drastic reaction was not observed in the same ankles under only the ankle stretch. There was no such drastic reaction in the unaffected ankle under either testing condition. This pilot finding indicates a possibility of a hyper-reactivity to unloading reaction in the ankles with functional ankle instability

The Mean

Purpose. To determine the effect on intraocular pressure of transpalpebral specific exogenous voltages in a cohort of open-angle glaucoma patients. Methods. This is a prospective, comparative, and experimental pilot study. The electrical stimuli applied consisted of 10 Hz, biphasic, nonrectangular current pulses (100 μA) delivered from an isolated constant current stimulator. At intake, baseline IOP measurements were obtained from each eye. The measurement was repeated before and after microstimulation until the end of the treatment. Results. Seventy-eight eyes of 46 patients diagnosed with POAG were studied: 58 eyes with maximum tolerated medical treatment and 20 eyes without treatment (naïve). The mean baseline IOP on the treated POAG group was 19.25 mmHg ± 4.71. Baseline IOP on the naïve group was 20.38 mmHg ± 3.28. At the four-month follow-up visit, the mean IOP value on the treatment group was 14.41 mmHg ± 2.06 (P<0.0001). The obtained mean IOP measurement on the treatment-naïve group was 15.29 mmHg ± 2.28 (P<0.0001). Conclusions. The hypotensive response obtained using transpalpebral electrical stimulation on POAG patients, both on treatment-naïve patients and on patients receiving maximum tolerable treatment, was statistically significant when comparing basal IOP measurements to those obtained at the four-month follow-up visit.

Chronic constipation in patients with multiple sclerosis (MS) is common and the current methods of treatment are ineffective in some patients. Anecdotal observations suggest that functional electrical stimulation (FES) of the abdominal muscles may be effective in the management of constipation in these patients.Patients and Methods. In this exploratory investigation we studied the effects of FES on the whole gut transit time (WGTT) and the colonic transit time (CTT). In addition, we evaluated the treatment effect on the patients’ constipation-related quality of life and on the use of laxatives and the use of manual bowel evacuation. FES was given for 30 minutes twice a day for a period of six weeks. Four female patients were studied.Results. The WGTT and CTT and constipation-related quality of life improved in all patients. The patients’ use of laxatives was reduced. No adverse effects of FES treatment were reported.Conclusion. The findings of this pilot study suggest that FES applied to the abdominal muscles may be an effective treatment modality for severe chronic constipation in patients with MS.
