Clinical Trial Summary

The cold pack application, which is a special silicate gel impregnated with water in a soft rubber envelope, is frequently applied in the clinic. It has been shown in the literature that local cold application causes increased resistance to movement. It is also reported that the muscle can change its mechanical properties in a short time. However, the effect of the cooling package application applied in different periods on the mechanical properties of the muscle is unknown. Therefore, in the current study proposal, the investigators aim to investigate the acute effect (0 min, 5 min, 10 min, 15 min, 20 min and 30 min) of cold pack therapy applied on healthy individuals for different periods (10-12-15-20 minutes).

Clinical Trial Description

Cold Packs (Cold Pack, CP); Slika gel packs are the most commonly used modalities in clinics. Special silicate gel impregnated with water in a soft rubber envelope is stored in coolers whose temperature is maintained between -12.2 ° C and 9.4 ° C . There are different sizes and shapes. Since it does not lose its softness when it is cooled, it adapts well to the folds of the body. By putting a towel between the skin and the package, a homogeneous cooling is tried to be achieved, hygiene is provided and it is easier to tolerate the feeling of extreme cold felt in the first contact of the cold package. It can be applied for a relatively long time without losing its cold due to its low conductivity. Significant increase in package temperature is seen from the 15th minute of the application. It is stated that it decreases the skin temperature up to 10 ° C and keeps it at 20 ° C-30 ° C for 3 hours depending on the room temperature. They can be used repeatedly by cooling .

Intensive cold application for 12-15 minutes is enough to reduce pain and muscle spasm . It has also been shown that a cold application over 30 minutes can cause cold bite and nerve problems . However, in practical applications, cold appears to vary between 15-30 minutes for pain, muscle spasm and edema . In a review made by Auley regarding cryotherapy treatments; ice application has been shown to be used in 5 to 85 minutes in many studies. They said that cold application does not have a specified frequency and duration, but repeated 10 minutes of cold application is effective. In addition, it has been reported that there is evidence of a slightly less drop from 10 minutes to 20 minutes while the temperature drops in the first 10 minutes .

In animal studies performed in vitro, although muscle tissue has reported high resistance to strain after cooling, direct mechanical responses to muscles in human studies There is only one study that evaluates. In this study carried out by Mustalampi et al., Parameter measurements indicating the mechanical properties of the muscle immediately after applying the cold pack applied locally to the quadriceps muscle for 20 minutes and after 15 minutes. As a result of the study, the muscle has become stiffer, less elastic in terms of mechanical properties and it has been shown that these changes do not completely recover after 15 minutes. It was not observed when it was reinstated after fifteen minutes.

In the light of this information, in the current study proposal; the investigators aim to investigate the acute effect (0 min, 5 min, 10 min, 15 min, 20 min and 30 min) of the cold pack therapy on the mechanical properties of the quadriceps muscle in healthy people for different periods (10-12-15-20 minutes). ;
