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

Summary

The goal of this clinical trial is to evaluate whether intensive sensory stimulation therapy can improve upper limb motor skills and sensory function in children aged 12-16 years with severe symptoms of Developmental Coordination Disorder (DCD). The main questions it aims to answer are:

1. Will children with DCD who undergo intensive sensory stimulation therapy show greater improvement in upper limb motor function compared to those receiving standard therapy?
2. Will intensive sensory stimulation therapy lead to better sensory function outcomes, including joint position sense, resistance sense, pressure sense, temperature perception, and two-point discrimination? Researchers will compare children receiving intensive sensory stimulation therapy to those receiving standard therapy without intensive sensory stimulation to see if the targeted intervention results in superior improvements in motor and sensory function.

Conditions

• Developmental Coordination Disorder

Interventions

OTHER

Active and passive physical therapy without intensified sensory stimulation

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

OTHER

Active and passive physical therapy with intensified sensory stimulation

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.
