It is also an inherent part of patients’ self-administered pain treatment. This review aims to update the evidence for thermal therapy treatments in non-specific chronic low back pain patients and to rate the methodological quality of the corresponding clinical trials. Previous studies have reported contradictory evidence for the effectiveness of thermal therapy. An electronic search on MEDLINE (PubMed), PEDro, CENTRAL and CINHAL databases was conducted between May 2016 and February 2018. Clinical trials comparing local thermal therapy to conservative or no treatment were assessed for eligibility. Pain, physical function and global health were defined as outcome parameters. A total of n = 9 studies met the inclusion criteria. All of them applied an electrophysical agent as the thermal treatment: continuous ultrasound (n = 6), short-wave diathermy (n = 2), microwave diathermy (n = 1). Out of the n = 6 studies on ultrasound treatment, n = 2 reported significant within and between-group results for pain reduction after 4 to 6 weeks of treatment. Both short-wave diathermy studies demonstrated significant between-group results for pain reduction after 3 weeks of treatment. Contradictory results for all other observed outcome parameters were reported regardless of the intervention. Moreover, significant within-group results for the control groups questioned the effectiveness of the intervention treatments. Therefore, the effect of thermal therapy, (electrophysical agents), is not superior to any control treatment except for ultrasound treatment on short-term pain reduction.展开更多

Kim argues that if mental and physical properties are distinct, then mental properties are causally irrelevant. My task in this paper is to refute this argument and to provide a solution for the problem of mental causation. Taking mental properties as higher-order properties, I attempt to propose a property-exemplification account of events that is compatible with the thesis of token identity. I then attempt to refute the exclusion argument by arguing that mental causation and physical causation are not homogeneous; that is, they are two different kinds of causation. Kim＇s exclusion argument only demonstrates the impossibility of a productive conception of mental causation; however, only a difference-making conception is appropriate for mental causation and human agency. If these results are plausible, they would serve as a metaphysical basis for an autonomy approach to mental causation, which attempts to save the causal relevance of mental properties by arguing that there is only intra-level causal relevance.展开更多

Some non-reductive physicalists address this problem by arguing that mental properties are to some extent causally autonomous. If this is the case, then mental properties will not be causally excluded by their physical realizers because causation, in general, is a relation between properties of the same level. In this paper, I argue that the response from causal autonomy cannot be successful for two reasons. First, it does not offer a satisfactory explanation for how mental particulars can have causal efficacy in a non-reductive physicalist framework. Second, the causal considerations underpinning this response do not really support the conclusion that mental properties are causally autonomous.展开更多
