Background: Patients with brachial plexus avulsion (BPA) usually experience phantom sensations and phantom limb pain (PLP) in the deafferented limb. It has been suggested that evoking the sensation of touch in the deafferented limb by stimulating referred sensation areas (RSAs) on the cheek or shoulder might alleviate PLP. However, feasible rehabilitation techniques using this approach have not been reported. Objective: The present study sought to examine the analgesic effects of simple electrical stimulation of RSAs in BPA patients with PLP. Methods: Study 1: Electrical stimulation of RSAs for 60 minutes was conducted for six BPA patients suffering from PLP to examine short-term analgesic effects. Study 2: A single case design experiment was conducted with two BPA patients to investigate whether electrical stimulation of RSAs was more effective for alleviating PLP than control electrical stimulation (electrical stimulation of sites on side opposite to the RSAs), and to elucidate the long-term effects of electrical stimulation of RSAs. Results: Study 1: Electrical stimulation of RSAs evoked phantom touch sensations in the deafferented limb, and significantly alleviated PLP (p <  0.05). Study 2: PLP was alleviated more after electrical stimulation on RSAs compared with control electrical stimulation (p <  0.05). However, the analgesic effects of electrical stimulation on RSAs were observed only in the short term, not in the long term (p >  0.05). Conclusions: Electrical stimulation of RSAs not only evoked phantom touch sensation but also alleviated PLP in the short term. The results indicate that electrical stimulation of RSAs may provide a useful practical rehabilitation technique for PLP. Future studies will be required to clarify the mechanisms underlying immediate PLP alleviation via electrical stimulation of RSAs.

The anticipation of acupuncture, simple insertion of needles or the electrical stimulation of needles at both classical acupuncture points and "false" points, all produce an increase in white blood cell count. Electrostimulation produced the greatest, expectation of needle insertion the least, increase in white cell count. Though needles remain to place, the white cell count returns to basal level within one hour. Preliminary data on peripheral skin temperature as affected by stimulation of acupuncture points and non-points, suggests a higher temperature on the side of stimulation. For acupuncture site stimulation, the temperature differential appears to be more persistent than is true when non-sites are stimulated. Subjects reported needle insertion at acupuncture points as less painful than at non-points. Feelings of numbness were produced by stimulation of both classical and false acupuncture points.

Spinal cord injuries (SCI) result in the loss of movement and sensory feedback as well as organs dysfunctions. For example, nearly all SCI subjects loose their bladder control and are prone to kidney failure if they do not proceed to intermittent (self-) catheterization. Electrical stimulation of the sacral spinal roots with an implantable neuroprosthesis is a promising approach, with commercialized products, to restore continence and control micturition. However, many persons do not ask for this intervention since a surgical deafferentation is needed and the loss of sensory functions and reflexes become serious side effects of this procedure. Recent results renewed interest in spinal cord stimulation. Stimulation of existing pre-cabled neural networks involved in physiological processes regulation is suspected to enable synergic recruitment of spinal fibers. The development of direct spinal stimulation strategies aiming at bladder and bowel functions restoration would therefore appear as a credible alternative to existent solutions. However, a lack of suitable large animal model complicates these kinds of studies. In this article, we propose a new animal model of spinal stimulation -pig- and will briefly introduce results from one first acute experimental validation session.

AbstractA description is given of the sexual behaviour of 16 longicorn beetles of the subfamily Lepturinae. The following points have been investigated:- 1. Stimulation of the female performed by the male either as a "licking" or combined "licking and tapping" of the female elytra or the grasping of an antenna of the female. 2. Movements of the antennae of the male, which seem to be an expression of the "state of excitement" of the male. These movements are in principle thought to be one of the behaviour patterns originally present in the order Coleoptera. 3. A "round dance", one of the methods for the female to throw off the male after copula, is described. 4. A selection of partner according to size is described in the genus Rhagium. 5. A comparative analysis is attempted for some species and systematic conclusions of such comparisons are proposed.
