“…The arms of subjects in the other 2 groups, who were not exposed to the heat of the Fluidotherapy unit, did not demonstrate a decrease in SNAP latency. This inverse relationship between cutaneous temperature and SNAP latency supports the findings of Abramson et al 1 and Greathouse et al, 6 among others. 2,5,8,15 However, this is the first study to have demonstrated this relationship as a result of Fluidotherapy treatment.…”

“…Madsen and Gersten, 16 as well as Zankel,25 documented decreased conduction velocities of various motor nerves and the ulnar nerve following ultrasound application. However, the balance of literature has reported an inverse linear relationship between latency and temperature change, 1,2,5,6,8,15 with increasing temperature resulting in decreased latency (increased conduction velocity). Abramson et al 1 demonstrated increased conduction velocity of the median and ulnar ner ves following shortwave diathermy and topically applied heat.…”

Study Design: Cross-sectional study. Objectives: The purpose of this study was to examine the effects of the superficial heating modality, Fluidotherapy, on skin temperature and on sensory nerve action potential (SNAP) conduction latency and amplitude of the superficial radial nerve in healthy individuals. Background: Fluidotherapy is a dry, superficial heating modality, which also provides tactile stimulation through the bombardment of air-fluidized cellulose particles. Previous literature has documented a direct relationship between skin temperature and neural conduction velocity; however, there is an absence of published research examining the effects of Fluidotherapy, and of tactile stimulation specifically, on neural conduction. Methods and Measures: Twenty-one subjects between the ages of 22 and 31 years (mean ± SD, 25.5 ± 0.7 years) and without prior history of diabetes, alcoholism, renal or metabolic dysfunction, current pregnancy, or heat sensitivity were invited to participate. Subjects completed an upper quarter screening exam and medical history form prior to participation. One group underwent heat (46.7°C-48.9°C) and tactile stimulation, a second group underwent tactile stimulation alone, while a third served as controls. Dependent variables were assessed at 3 intervals: before the intervention, immediately after the intervention, and 20 minutes after the intervention. All interventions were 20 minutes in length. Results: A mixed 2-way analysis of variance indicated a significant interaction between time of neural conduction velocity assessment and treatment group for the dependent variables of sensory nerve action potential latency (PϽ .001) and skin temperature (PϽ .001). Appropriate post hoc tests were performed for simple effect comparisons. An inverse linear relationship existed between skin temperature and latency (r 2 = .65; Pearson product coefficient, -.81). Conclusions: Fluidotherapy treatment, which combines the effects of heat and tactile stimulation, significantly elevated superficial skin temperature, while tactile stimulation alone and no treatment (control group) did not bring about a temperature change. As the superficial skin temperature increased, there was a concomitant decrease in the distal sensory latency of the superficial radial sensory nerve action potential. These results should be an important consideration for the clinician using superficial heating modalities. J Orthop Sport Phys Ther 2005;35:16-23.

Sixty patients undergoing total knee replacement were randomized to receive either a cold compression dressing (Cryo/Cuff, Aircast, UK) or a modified Robert Jones bandage immediately after surgery. The cold compression dressing was used for a minimum of 6 h per day throughout the hospital stay, and the modified Robert Jones bandage remained in place for 48 h from the time of operation. The 2 groups of patients were compared during their hospital stay for blood loss, range of movement, pain scores and need for analgesia. No difference was found between the 2 groups except for less blood loss in the surgical drains in the cold compression group (P<0.05). Postoperative complications were seen in both groups, but no complication was associated with either the cold compression dressing or the modified Robert Jones bandage. Résumé Etude randomisée de 60 patients qui, immédia-tement après une arthroplastie totale du genou ont eu soit un pansement compressif froid de type "Cryocuff" soit un pansement compressif de type Robert Jones. Le pansement froid a été utilisé 6 heures par jour pendant la durée de l'hospitalisation tandis que le pansement compressif de type Robert Jones a été laisse en place pendant 48 heures après l'opération. Aucune différence statistiquement significative n'a pu être mise en évidence entre les deux groupes, à l'exception des pertes sanguines dans le drainage, moins importantes dans le premier groupe de patients. Nous avons eu des complications post opératoires dans les deux groupes mais aucune corrélation n'a pu être établie entre ces complications et le type de bandage appliqué.

“…Muscle activity intensity displayed a similar trend in Eurycea, another plethodontid salamander (Anderson et al, 2014), but is independent of temperature during tongue projection in toads (Deban and Lappin, 2011) and chameleons (Anderson and Deban, 2012). The precise physiological limitations underlying reduced muscle activity intensity at low temperatures in plethodontid salamanders is not known, but may stem from changes in motor unit recruitment or reduced nerve conduction at low temperatures (Abramson et al, 1966;Rome et al, 1984;Jayne et al, 1990;Hill et al, 2008).…”

Elastic-recoil mechanisms can improve organismal performance and circumvent the thermal limitations of muscle contraction, yet they require the appropriate motor control to operate. We compare muscle activity during tongue projection in salamanders with elastically powered, ballistic projection with activity of those with musclepowered, non-ballistic projection across a range of temperatures to understand how motor control is integrated with elastically powered movements, and how this integration contributes to reduced thermal sensitivity. Species with ballistic tongue projection activated and deactivated their projector muscles significantly earlier than nonballistic species, in a pattern consistent with a mechanism in which the muscle strains elastic tissue that subsequently recoils to power projection. Tongue projection was more thermally robust in ballistic species, but in both ballistic and non-ballistic species the projector muscles were activated earlier and for longer as temperature decreased. The retractor muscles showed a pattern similar to that of the projector muscles, but declined in a similar manner in the two groups. Muscle activity intensity also decreased at low temperatures in both groups, revealing that compensatory muscle activation does not account for the improved thermal robustness in ballistic species. Thus, relatively minor shifts in motor patterns accompanying morphological changes such as increased elastic tissue are sufficient to improve performance and decrease its thermal sensitivity without specialization of muscle contractile physiology.
