Inclusion Criteria:  Children  Participating children are between the ages of 5-10 years, and - if already in occupational therapy - have at least six more therapy sessions planned. Participating children must be motivated to participate in the study and have difficulties in graphomotor skills, of which at least two of the following criteria must apply:  The child complains of pain when writing/drawing. The child's knuckles turn white due to high grip pressure when writing. The distal interphalangeal joint of the index and or middle finger is severely hyperextended when writing / drawing The writing imprints on the next page when writing / drawing The child has to take regular breaks when writing / drawing in order to relax the hand. The child's hand slides to the tip of the pencil when writing / drawing because the pencil is held too loosely The child's writing/drawing is difficult to see because too little pressure is being applied The pen slips out of the child's hand when writing / drawing The child cannot guide the pencil sufficiently because it is held too loosely The child frequently breaks the pencil lead while writing or drawing or pushes a felt-tip pen lead into the pencil. Grip pressure or pressure on the paper varies greatly during writing / drawing  Other than the graphomotor problems, participating children must have the following cognitive abilities to participate in the study:  Sufficient language and task comprehension to follow instructions Ability to follow simple verbal instructions Maintenance of attention for 10 minutes during graphomotor activities at the table  In addition, the following motor skills must be present to hold the pencil:  No stiffened joints in the finger and hand area (sufficient gripping function and finger mobility), so that it is possible to both hold objects in the hand and move them while holding them in the hand. No excessive or insufficient muscle tension at rest (hyper-/hypotonia) in the upper extremities or writing hand, so that it is possible to hold a pen in the hand.  Additionally, participating children must confirm their consent to participate in the study in writing via a child-friendly Informed Consent (IC) form. Furthermore, a parent/guardian must confirm the child's participation in the parent/guardian IC by signature in each case.  Occupational Therapists  Participating occupational therapists possess at least two years of professional experience in the occupational therapy assessment and treatment of children, in which context participants also treat children with graphomotor problems in an activity-based manner. Furthermore, the participating occupational therapists have at least average technical affinity (handling of a normal tablet is possible). Occupational therapists will only be involved if the IC has been completed and signed.  Legal Guardians  Legal guardians are included if the IC has been filled out completely, signed and if participants have at least average technical affinity (necessary in case of "home use" of the SensoGrip pen by the child).  Exclusion Criteria:  Children  Children will be excluded from participating in the study if there is a concurrent participation in another study related to graphomotor skills, their age is inappropriate, the adequate development of motor and cognitive skills is not present, or if there are significant problems in the area of psychosocial skills such as critical thinking skills, emotion regulation, or frustration tolerance.  Occupational Therapists  Occupational therapists will not be recruited for the study if their work with children is exclusively focused on the gross motor area, therapists are specialized in other areas and do not have sufficient professional experience. Further exclusion criteria are the rejection of technical tools in therapy and serious uncertainties or fears in the use of technologies.  Legal Guardians  Legal guardians are excluded if participants generally reject the use of technical devices or have serious insecurities or fears regarding the use of the technology.
