简要总结
Cryotherapy has a wide range of clinical applications in rehabilitation, used for activities such as controlling inflammation, pain control or management of edema after an injury or surgery. In the field of cryotherapy they studied cold neuromuscular responses, where it has shown a decrease in nerve conduction velocity, which leads to a decrease in muscle strength. However it has been described in some work applications brief cold ("Quick Icing") may be opposite to those described effects, increasing the strength, the time of intervention the most important and decisive in these possible improvements or decreases factor. This effect is observed in response to a few seconds of application of cold, and would be given by an increased activity of motor neurons. Assess the influence of rapid cooling application ("Technique Quick Icing") and prolonged cooling in handgrip strength when performing a manual dynamometer test in college students.
详细描述
Methodology
- Type of study: Experimental study, type randomized clinical trial (RCT).
- Conceptual framework:
- Quick or rapid cooling Icing: brief application of cold, for a period of up to 30 seconds on a body surface which seeks to promote the activation of the nervous system to produce increased excitability.
- Prolonged Cold: prolonged application of cold, for at least 5 minutes or more, on a body surface that aims to reduce nervous system activation slowing of nerve conduction.
- Operational definition of variables:
- Grip strength: Strength in kilograms evaluated through manual dynamometry test the time for a grip. Force values are recorded in an Excel table displaying data in kilograms evaluated. (Manual hydraulic dynamometer brand JAMAR® be used).
- Quick Icing: will apply through glasses of ice on the ventral region of the dominant forearm of the experimental group.
- Prolonged cold: It shall be implemented through an ice pack (ice bag), placed on the ventral side of the dominant forearm in one of the comparison groups.
- Control: Group of people will not be subjected to any intervention.
- Sample:
Place of research: The study will be conducted in the laboratory of physiotherapy rehabilitation science faculty building C5 401 room floor room, campus Casona de la Universidad Andrés Bello, Av Fernández Concha 700, Las Condes. 5. Methodological Design
