Influence of Sensory Stimulation on Sensory Parameters and Motor Function in Children With Developmental Coordination Disorder

"Intervention: Passive and active therapy without high sensory stimulation Duration: 4 weeks Frequency: 3 sessions per week Session duration: 60 minutes~Intervention structure:~Passive therapy (30 minutes):~• Stroking and rubbing techniques from classic massage applied in the area of arm forearm and hand with low force and frequency upper limb massage - 15 minutes per limb~Active therapy (30 minutes): upper limb muscle strengthening exercises (without globalized vibration); difficulty level individually adjusted to meet participants' current potential, so that in the last sets/reps little manual assistance from the therapist is needed:~* Supine pull-ups - 3 sets of 8 reps, \~45 seconds rest between sets~* Standing pull-ups - 3 sets of 8 reps, \~45 seconds rest between sets~* Standing push-ups - 3 sets of 8 reps, \~45 seconds rest between sets~* Standing elbow extensions - 3 sets of 8 reps, \~45 seconds rest between sets"

"Intervention: Passive and active therapy incorporating high sensory stimulation Duration: 4 weeks Frequency: 3 sessions per week Session duration: 60 minutes~Intervention structure:~Passive therapy (30 minutes): stimulation of joint receptors, muscle spindles, and tactile pathways:~* High-frequency soft tissue mobilisations~* Localised high-amplitude vibration (30-50 Hz; Galileo Mano 30, Novotec Medical GmbH)~* Deep pressure techniques - Wilbarger brushing protocol followed by joint compressions Active therapy (30 minutes): upper limb and shoulder girdle muscle strengthening exercises with globalized vibration using Redcord Stimula (30-50 Hz; Redcord AS, Norway); difficulty level individually adjusted to meet participants' current potential. Excercises the same as in the control group."
