Background: Radiofrequency treatment is a rapidly growing in popularity procedure in musculoskeletal rehabilitation due
to its effectiveness and efficiency in accelerating tissue healing while remaining noninvasive. The most commonly used and
researched are the INDIBA activ technology that operates at 448 kilohertz. INDIBA® activ radio frequency therapy can be
applied either with no significant pressure on the skin but also in the form of soft tissue mobilization technique with specific
IASTM electrodes utilizing INDIBA® Fascia treatment. This study aimed to examine the thermal skin responses to 448 kilohertz
radio frequency based therapy applied either in the form of standard application INDIBA ®activ or the form of combined soft
tissue treatment INDIBA® Fascia treatment.
Methods: Forty college students from the Technological Educational Institute of Western Greece were randomly divided into
four groups and received a single, 10 minute hyper thermic (maximum amount of thermal intensity that can be handled)
treatment of their hamstrings in the form of a standard INDIBA ®activ application -IA group b) INDIBA ® Fascia soft tissue
mobilization application - IF group, c) INDIBA ®activ Placebo - IAP group and d) INDIBA® Fascia placebo application -IFP
group. Placebo groups received same treatment applications but with no radio frequency passing through the electrodes. Local
skin temperature was measured before, immediately, post treatment and up to the point was returned to the baseline value.
Results: Statistically significant differences (f=62.701, p=0.00) in skin temperatures adaptations were found for the groups
receiving INDIBA® activ and INDIBA® Fascia treatment compared with those that received placebo treatment in figure 1.
Furthermore, there was a statistically significant difference (p=0.00) between the thermal response patterns produced by the
two treatment procedures as in the IA group the temperature was maintained above the baseline levels for 58 minutes while in
the group treated with the IF procedures for 130 minutes.
Conclusions: This study confirms that INDIBA® activ radio frequency treatment at 448 kilohertz can induce and sustain
significant thermal skin adaptations. These adaptations were impressive and lasted for a prolonged period over 2 hours. When
the application of radio frequency therapy (448 kilohertz) was done through soft-tissue mobilization procedure INDIBA® Fascia
treatment. This increase and long-term maintenance of elevated skin temperature are of critical importance in musculoskeletal
rehabilitation as rises in skin temperature are connected with increased blood circulation and metabolism of underlying tissues.
