“…The purpose of the study was to examine the effects of cupping therapy on the skin stiffness and ultimate tensile strength in Wistar rats. According to the results of the study, cupping therapy decreased the skin stiffness and ultimate tensile strength significantly which has also been shown in Schneider et al study [17]. While the results were the same, pulling directions of the skin were different in the two studies.…”

“…While the results were the same, pulling directions of the skin were different in the two studies. In the present study, the tensile stresses pulled the skin in all directions, while in Schneider et al study [17] the tensile stresses were in two opposite directions. It suggests that the direction of stress may have no effect on the skin stiffness and ultimate tensile strength.…”

“…Ultimate tensile strength is the maximum strength of tissue against the tensile stress that is the highest point of the stress-strain curve [15] [16]. Schneider et al examined the biomechanical changes of expanded skin conducted on pigs and found out that tissue expanders could reduce the skin stiffness and tensile strength [17]. It has been reported that the histological and histomorphological changes due to the tensile stress can change the biomechanical properties of the skin [18] [19].…”

Cupping therapy has been widely used for clinical treatment of soft tissue lesions. The current study investigated the effects of cupping therapy on biomechanical properties of the skin in Wistar rats. 20 rats were divided into two groups: 10 in experimental and 10 in control group. Either the right or the left lower quadrants of the lumbar regions in the experimental group underwent 10 minutes daily cupping therapy for 12 days. The skin stiffness and ultimate tensile strength of all the rats were measured using tensiometer. The skin stiffness and ultimate tensile strength were decreased significantly in cupping side of the experimental group as compared with the non-cupping side and the control group. There were no significant differences between the non-cupping side of the experimental group and the control group. In conclusion, cupping therapy can be useful as a treatment method to reduce the skin stiffness and ultimate tensile strength.

“…The magnetic field will be affected while nonferromagnetic metal debris is near to the microcoil as shown in Figure 1(b). The eddy current will be generated in the metal debris because of the alternating magnetic field [11]. The direction of the magnetic field that generated by eddy current is opposite to the magnetic field that generated by the microcoil.…”

The debris detection system is simulated and analyzed with the software of Maxwell 14 in this paper. The magnetic induction intensity and the magnetic density of the detection system with metal debris are simulated. The static experimental system is designed to measure the inductance caused by different metal debris. The simulation and experimental result indicate that the nonferromagnetic metal debris reduces the inductance of microplane inductance sensor and that ferromagnetic metal debris increases the inductance of microplane sensor. The detection of metal debris with microplane sensor is feasibly proved by the research. This paper provides a model for detecting the debris with a plane eddy current sensor and a case for the 3D simulation of the eddy current. This work may have some significance for improving the efficiency of the plane eddy current sensor.

“…Overall, expanded skin demonstrated an average of 35% reduction in tensile strength. 15 The maximum amount of additional skin obtained from prolonged tissue expansion has not been studied, but is probably related to the rate and duration of the expansive process and to the intrinsic tensile strength of the expanded skin. Machida et a1.16 produced a mean increase in skin surface area of 135% by expanding guinea pig skin over a 6-week period.…”

The relatively recent advent of tissue expansion for medical purposes precludes the availability of extensive knowledge concerning the physiologic and histologic changes that occur during controlled expansion of the skin. This paper reviews the basic science and clinical research that has been conducted to investigate the changes and summarizes the findings. It can be concluded that flaps harvested from skin previously expanded have an improved survival rate compared to similar flaps developed in nonexpanded skin. Increased vascularity to either the skin, the capsule that forms around the expander, or both probably in some way accounts for the improved survival. Controlled expansion of the skin results in the creation of additional new skin at the expense of thinning the dermis and subcutis. This thinning is associated with an overall decrease in tensile strength of the expanded skin. The increase in surface area gained from skin expansion probably varies according to the type of skin expanded and the underlying tissues that serve as a foundation for the expander.
