Acute Effects of Cryotherapy Duration in Healthy Individuals
Condition: Cryotherapy Effect
Study type: Interventional

Summary: 
      The study will investigate the acute effects of cryotherapy duration on shoulder muscle
      strength, flexibility, endurance and dynamic balance in healthy individuals.
    

Detailed description: 
      Cryotherapy is a practice that induces therapeutic effects by reducing tissue temperature to
      produce an analgesic effect. Cryotherapy application methods vary from simple ice packs and
      cold water immersion to whole body cryotherapy methods. The purpose of cryotherapy treatment
      is to reduce tissue damage, muscle spasm, edema and pain and to provide a faster
      rehabilitation process after injury. It is also used as a recovery technique after
      high-intensity training in different sports branches. Despite the proven benefits of
      cryotherapy according to the literature, discussions continue about its effect on some
      parameters and there is no consensus on the duration of cryotherapy application. In addition,
      although there are studies on the effects of cryotherapy on the lower extremities, studies
      for the upper extremity are limited and the results of these studies are inconsistent. In the
      literature, no study was found that evaluated the effect of cryotherapy application time on
      shoulder muscle strength, endurance, flexibility and balance. Therefore, in this study, the
      acute effects of cryotherapy duration on shoulder muscle strength, flexibility, endurance and
      dynamic balance in healthy individuals will be investigated and the optimum duration of
      cryotherapy on these parameters will be determined. In addition, the results of the research
      will contribute to the planned rehabilitation and exercise program.
    

Intervention name(s): Cryotherapy application
Intervention type(s): Other
Intervention description(s): The temperature sense test was applied on the dominant side shoulder of the participants against the risk of sensory loss or decreased sensation. In order to test cold intolerance, a cold pack was placed on the forearm of the individuals. After waiting 2-3 minutes, the region was evaluated. Individuals meeting the inclusion criteria were assigned to the groups according to the randomization list created by the computer. Then, the participants' shoulder isometric muscle strength, shoulder flexibility, shoulder endurance and shoulder balance was evaluated. Except for shoulder endurance, all measurements were repeated three times, with a 30-second rest period between each repetition. A 2-3-minute rest period was given after each test. Then, the cold pack was wrapped in a thin and wet cloth on the shoulders of the participants. The treated area was checked every 5 minutes and the participants were asked to say when they felt any unusual symptoms.
Allocation: Randomized
Intervention model: Parallel Assignment
Intervention model description: Individuals aged 18-25 years who volunteer to participate in the study will be included in this study and randomly assigned to 3 groups. After the demographic information of the volunteers is obtained and their dominant upper extremities are determined, the shoulder isometric muscle strength will be measured with a hand dynamometer. The back scratch test will be used to evaluate the shoulder flexibility of the participants, the modified push-up test will be used to evaluate the endurance, and the upper extremity Y balance test will be used to evaluate the shoulder dynamic balance. Then, cryotherapy will be applied on the shoulder for 10 minutes in Group 1, 15 minutes in Group 2 and 20 minutes in Group 3.After the application, the same measurements will be repeated and the values before and after the application will be compared.
