## 1 Introduction  
Functional appliances used in the correction of Class II malocalclusions are demonstrated to modify the neuromuscular environment of the dentition and surrounding skeletal structure [1; 2]. In growing patients, a two-phase approach to managing Class II skeletal malocclusions--consisting of an initial growth modification using functional appliances followed by subsequent treatment with fixed appliances--has been recommended as an effective treatment strategy [3; 4]. For patients with skeletal Class II malocalclusions who are still growing, growth modification should be regarded as the primary option for the correction of skeletal deformity [5]. One of the most widely used functional appliances for orthopedic correction of Class II skeletal malocalclusions is the Twin Block (TB). Due to its simple design and ease of use, the TB can be worn 24 h a day and takes full advantage of all the functional forces applied to the dentition, including those of mastication [6]. An additional benefit of the Twin Block (TB) appliance is its compatibility with fixed appliances [7]. There are studies in the literature showing the clinical and psychological effects of the Twin Block and functional appliances. A review comparing early treatment with a functional appliance versus late treatment revealed that early intervention resulted in greater reductions in both the overjet and ANB angle, favoring the use of functional appliances [8]. The same review also reported that early intervention with functional appliances was associated with a reduced incidence of incisal trauma compared to late treatment [8]. Similarly, another review established a correlation between increased overjet and the incidence of traumatic dental injuries [9]. Children with an overjet greater than 3 mm are at a higher risk of suffering traumatic dental injuries [9]. Another study assessing the psychological effects of Twin Block (TB) therapy found that children who received early orthodontic treatment with the TB reported higher self-concept scores and more positive childhood experiences compared to the control group that did not receive orthodontic treatment [10]. The second article of this study indicates that patients who received TB therapy perceived changes in their speech and sleep patterns [11]. Skeletal Class II malocclusions are usually caused by mandibular retrognathia [12], and their orthopedic treatment involves the use of fixed or removable functional appliances that modify the amount and direction of jaw growth [13]. When modifying growth, functional appliances predominantly focus on the temporomandibular joint (TMJ) region [14]. Although the mechanism of action of these appliances on condylar growth remains unclear, they may induce adaptive changes in the condylar cartilage or glenoid fossa [15]. The most common concern for patients undergoing functional appliance therapy is the long duration of treatment [16]. For physicians, the concern is the efficacy of functional therapy and post-treatment relapse. Thus, functional therapy aims to stimulate optimal cellular activity in the condyle over a short treatment period. In this context, novel noninvasive approaches that induce mandibular growth in a short period of time without causing any adverse effects are required. At present, advances in science and technology allow orthodontists to accelerate condylar cartilage growth [17]. Some researchers have considered innovative methods of laser and ultrasound applications to stimulate condylar growth, with or without functional appliances [18]. One of these innovative methods is Kinesio taping (KT), which is now widely used by athletic trainers, physiotherapists, and physicians. This non-invasive technique was developed in 1970 as an alternative to athletic taping, which is used to support the fasciae, muscles, and joints by acting on the skin on which it is applied. KT lifts the upper layer of the skin, which increases the interstitial space and thus improves blood and lymphatic circulation [19], thereby reducing inflammation [19].
