Herapy in Superficial Radial Nerve ConductionNPL at all time points as compared to the sham light therapy group. Moreover, Figure 2 demonstrates the corresponding unfavorable correlation on the NCV in connection to the prolonged NPL. At each and every time point, the NCV for the light therapy group was slightly decreased as in comparison to the placebo group. Though these trends have been not important, they had been comparable to the NPL and NCV trends observed in prior research (38) working with the superficial radial nerve model of nerve conduction. Our observed trends had been also consistent with observations in studies making use of other peripheral nerve models of nerve conduction like the median (34,36,37) or sural nerves (29,30). Regardless of such trends, the non-significant benefits reported listed below are in keeping with earlier findings for other research (32) that examined the putative effects of light therapy around the conduction from the superficial radial nerve. Our findings do contradict other studies that suggest light therapy modalities, like laser and light emitting diodes, alter conduction properties with the superficial radial (34,37), median (36) and sural nerves (28-31). A confounding variable inside the literature that impacts the interpretation of and comparison involving conduction research is skin temperature. Previous literature demonstrates that there is a damaging correlation between distal latency and temperature whilst a optimistic correlation exists among nerve conduction velocity and temperature. In the present study we artificially manipulated the temperature PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/20069062 to maintain the limb skin temperature and prevent the previously reported 0.2 msec increase inside the distal adverse peak latency per degree (oC) lowering of temperature (32,33). However, the manipulation of skin temperature may have masked alterations in conduction induced through the application of light therapy. Several studies have demonstrated alterations in latency and conduction velocity after the application of light therapy without manipulation of skin temperature. Snyder-Mackler and Bork (32,33,39) reported a considerable increase in latency with a corresponding decrease inside the nerve conduction velocity for the superficial radial nerve after cold laser irradiation. In their study they maintained the room temperature at 23oC and showed a 0.37 msec increase within the latency from pre- to posttest. This observation would have required a 3.7oC drop in temperature to account for the reported difference. Since a large temperature drop in such a short treatment time (20 sec) was unlikely, they concluded that the difference in latency and NCV velocity was likelyFigure 3. Skin temperature differences ( oC) against time. Baseline represents time immediately prior to treatment (sham light therapy or light therapy), all others represent time (in minutes) following treatment (points represent means (SD); n=15 for both groups). The increases in temperature at each and every time point after treatment had been statistically different (P0.001) from baseline for light therapy and sham light therapy groups. However, there was no statistical difference involving groups at each time point.32.6 (0.8)oC. Concomitant skin temperature recordings for both groups are summarized in Figure 3, which shows temperature differences (oC; mean (SD)) plotted against time in minutes. This figure shows an increase within the temperature difference from baseline to each time point for both groups. The peak temperature for both groups was achieved at 2-minu.
