Chemotherapy-induced peripheral neuropathy (CIPN) is a highly prevalent and clinically relevant side-effect of cancer treatment. The severe symptoms such as loss of sensation, numbness, pain, absent reflexes or loss of balance control not only diminish children's quality of life but also affect the medical therapy. To date, there are no effective treatment options to reduce the symptoms of CIPN. Promising results have so far been achieved with specific exercise interventions.
The investigators would therefore like to conduct a prospective, multicenter, two-armed trial (RCT with follow-up). Patients (N=20) will be recruited from the Hospital for Children and Adolescents, Kantonsspital Aarau. Prior to randomization, all primarily eligible patients that have received a platin derivate or vinca-alkaloid, will be screened for symptoms of CIPN. Eligible patients with a neurologically confirmed CIPN will then be randomized either into an intervention group or a control group (CG). Patients in the intervention group will perform a standardized, age-adjusted, specific playful sensorimotor training (SMT) program twice a week for 12 weeks in addition to usual care, while the control group receives treatment as usual. The CG will be given the opportunity to participate in the intervention after study completion. Data change will be assessed at 3 time points: At baseline (T0), after 12 weeks (post intervention testing, T1), and after 12 weeks of follow-up (T2). Primary endpoint is the Ped-mTNS score in order to subjectively as well as objectively assess the severity of CIPN symptoms. It contains a short questionnaire as well as more objective parameters such as light touch sensation, pin sensibility, vibration sensibility, deep tendon reflexes and muscular strength. Additionally, the CIPN symptom pattern will be assessed via nerve conduction studies, CIPN related pain, dorsiflexion and knee extension as well as postural control. Furthermore, investigators will be evaluating patients' level of physical activity, walk to run transition time, lower limb power as well as patients integration in physical education (PE) in school and sport club activities. The investigators hypothesize that patients in the intervention group will be able to reduce relevant symptoms of CIPN, improving related physical functions and enhancing children's social reintegration.

| Sensorimotor training | Behavioral | Supervised training sessions will last for about 20 to 30 minutes in total, including a child-specific warm-up and cool-down. The children will be asked to maintain balance in a previously acquired "short-foot-position", knees slightly flexed (30°), without shoes. Training will consist of 5 playful balance exercises, chosen from a standardized pool of exercises according to the child's age, with increasing difficulty (5 degrees of difficulty - e.g. by reducing the base of support, or dual task exercises - per exercise depending on the age group) in order to allow for individual, optimal progression. Each of the 5 exercises will contain of 5 repetitions for 10sec. allowing for a 20sec. rest in between each set and a 1min rest between each exercise in order to avoid neural fatigue. Children will be given a training manual and diary to train at home after the study. Guardians will be instructed in order to be able to assist their children |

| Postural control | A force plate (Leonardo, Novotec, Pforzheim, Germany) will be used to assess changes in the center of pressure during upright static and dynamic stance. The assessment follows a standardized protocol. | Data will be assessed at 3 time points: At baseline (T0), post assessment after 12 weeks of intervention (T1) and after 12 weeks of follow-up (T2). |
| Dorsiflexion function | Ankle dorsiflexion strength and active ankle range of motion are measured using a hand-held dynamometer (Alluris, Freiburg, Germany) and a goniometer (Lafayette extendable goniometer), respectively. For measuring ankle dorsiflexion strength, participants are lying in a supine position; legs straight and foot maximal dorsiflexed. The responsible researcher places the dynamometer on the participant's inset of the foot and incrementally increases the force until the patient gives away (break technique). For measuring active ankle range of motion, two measurements are conducted; (1) children are sitting with straight legs (2) children are lying in a supine position with the legs supported by an adequate padding and the knees flexed to minimize potential impact of the flexibility of the gastrocnemius muscle. All dorsiflexion function measurements are carried out bilaterally and repeated two times, recording the best value of each foot as well as a mean value of both feet for analysis. | Data will be assessed at 3 time points: At baseline (T0), post assessment after 12 weeks of intervention (T1) and after 12 weeks of follow-up (T2). |
| Knee extension strength | In addition to ankle dorsiflexion strength, we will additionally assess knee extension strength to get a better overview of lower leg strength. To measure knee extension strength, a hand-held dynamometer (Alluris, Freiburg, Germany) and the break technique are used, as described in the section "dorsiflexion function". Participants sit upright with a hip and knee angle of 90°. | Data will be assessed at 3 time points: At baseline (T0), post assessment after 12 weeks of intervention (T1) and after 12 weeks of follow-up (T2). |
| lower limb power | Power and strength of the lower limbs are crucial for any kind of locomotor performance in daily life as well as sports participation. The countermovement jump test is a simple, functional, valid and highly reliable measurement of lower body power that is influenced by sensorimotor training. Following instruction and familiarization trials, children perform 5 consecutive countermovement jumps (CMJ) on a force-plate (Leonardo, Novotec, Pforzheim, Germany). The jumps are performed in an upright position with arms placed akimbo. The applied sampling frequency is 1000 Hz. Jumping height is computed using the flight time method. The best of the five attempts will be analyzed. Between jumps, a break of one minute will be provided. | Data will be assessed at 3 time points: At baseline (T0), post assessment after 12 weeks of intervention (T1) and after 12 weeks of follow-up (T2). |
| Walk to run transition time: | Fast walking demands a high intramuscular coordination and stability. People with decreased stability and coordination tend to transit from slow walking straight to running as this requires less strength and coordination. The walk-to-run-transition time is the preferred speed at which human change gait from walking to running and is defined as the initial moment where both feet are off the ground at the same time. To assess the participants' preferred walk-to-run-transition time, a treadmill test is performed. After a short familiarization on the treadmill (walking at various speeds), the test protocol provides an age-specific start-speed which is incrementally increased (every 10 seconds by 0,045 m/sec) by the researcher until the participant switches to a run for the first time. | Data will be assessed at 3 time points: At baseline (T0), post assessment after 12 weeks of intervention (T1) and after 12 weeks of follow-up (T2). |
| CIPN-related pain | In line with pharmaceutical studies to reduce the symptoms of CIPN, we will also measure intensity of CIPN-related pain using a FacesPain scale for children up to 12 years and a visual analogue scale (VAS) for children and adolescents aged 13 or older, both, starting at 0 = no pain, up to 10 = unbearable pain. These measurements have been reviewed and are recommended through the pediatric initiative on methods, measurement, and pain assessment in clinical trials (PedIMMPACT) group. | Data will be assessed at 3 time points: At baseline (T0), post assessment after 12 weeks of intervention (T1) and after 12 weeks of follow-up (T2). |
| Participation in PE as well exercise-related leisure activities | We would furthermore like to add questions concerning childrens' integration and participation in PE in school as well as in physically demanding leisure activities. For this purpose, children will answer the standardized questionnaire of the KiGGS study (German Health Interviews and Examination Survey for Children and Adolescents) (Bös 2009), offered in two different versions (for kindergartners and for students). Cancer- and treatment-related questions about potential barriers preventing from taking part in sporting activities are added (i.e. anxiety, prohibition by physician or parents or others, lack of time). All questions are answered via interview. | Data will be assessed at 3 time points: At baseline (T0), post assessment after 12 weeks of intervention (T1) and after 12 weeks of follow-up (T2). |
| Priority of side-effects | To assess the significance of CIPN, we would like to add a self-developed questionnaire regarding childrens' and parents' prioritization regarding the side-effects of chemotherapy. Therefore, typical CIPN symptoms, further side-effects of chemotherapy as well as their impact on the active lifestyle are described in age-appropriate language; subjective perception and perceived burden can be assessed on a five point-likert scale, respectively. | Data will be assessed at 3 time points: At baseline (T0), post assessment after 12 weeks of intervention (T1) and after 12 weeks of follow-up (T2). |
