The purpose of this study was to evaluate the accuracy and the intrarater reliability of arch angle (AA), Staheli Index (SI), and Chippaux-Smirak Index (CSI) obtained from ink and pressure platform footprints. We obtained AA, SI, and CSI measurements from ink pedigraph footprints and pressure platform footprints in 40 healthy participants (aged 25.65 ± 5.187 years). Intrarater reliability was calculated for all parameters obtained using the 2 methods. Standard error of measurement and minimal detectable change were also calculated. A repeated-measure analysis of variance was used to identify differences between ink and pressure platform footprints. Intraclass correlation coefficient and Bland and Altman plots were used to assess similar parameters obtained using different methods. Intrarater reliability was >0.9 for all parameters and was slightly higher for the ink footprints. No statistical difference was reported in repeated-measure analysis of variance for any of the parameters. Intraclass correlation coefficient values from AA, SI, and CSI that were obtained using ink footprints and pressure platform footprints were excellent, ranging from 0.797 to 0.829. However, pressure platform overestimated AA and underestimated SI and CSI. Our study revealed that AA, SI, and CSI were similar regardless of whether the ink or pressure platform method was used. In addition, the parameters indicated high intrarater reliability and were reproducible.

The abilities of children diagnosed with Obstetric Brachial Palsy (OBP) are limited by brachial plexus injuries. Thus, their participation in the community is hindered, which involves a lower quality of life due to worse performance in activities of daily living as a consequence of the functional limitations of the affected upper limb. Conventional Mirror Therapy (Conventional MT) and Virtual Therapy improve the affected upper limb functionality. Therefore, the aim of this study was to compare the effects of Conventional MT and Virtual Reality MT on the spontaneous use of the affected upper limb and quality of life of children with upper Obstetric Brachial Palsy between 6 and 12 years of age. A randomized pilot study was performed. Twelve children were randomly assigned to perform Conventional Mirror Therapy or Virtual Reality Mirror Therapy for four weeks. Ten children completed the treatment. Two assessments (pre/post-intervention) were carried out to assess the spontaneous use of the affected upper limb and the quality of life using the Children’s Hand-use Experience Questionnaire (CHEQ) and the Pediatric Quality of Life Inventory Generic Core Scales (PedsQL TM 4.0), respectively. There was a statistically significant increment in spontaneous use, observed in independent tasks (p = 0.02) and in the use of the affected hand with grasp (p = 0.04), measured with the CHEQ, for the Virtual Reality MT group. There were no statistically significant changes (p > 0.05) for the Conventional MT group in the spontaneous use of the affected upper limb. Regarding the quality of life, statistically significant changes were obtained in the Physical and Health activity categories of the parents’ questionnaire (p = 0.03) and in the total score of the children’s questionnaire (p = 0.04) in the Virtual Reality MT group, measured using the PedsQL TM 4.0. Statistically significant changes were not obtained for the quality of life in the Conventional MT group. This study suggests that, compared to Conventional MT, Virtual Reality MT would be a home-based therapeutic complement to increase independent bimanual tasks using grasp in the affected upper limb and improve the quality of life of children diagnosed with upper OBP in the age range of 6–12 years.

The movements of the affected upper limb in infantile hemiplegia are slower and clumsy. This leads to a decrease in the use of the affected hand. The visual effect obtained using the mirror box and the observation of actions in another individual can activate the same structural neuronal cells responsible for the execution of these actions. This research will study the affected upper limb functionality in hemiplegia infantile from 6 to 12 years old after the application of two intervention protocols: observation action therapy and mirror therapy combined with observation action therapy. Children with a diagnose of congenital infantile hemiplegia will be recruited to participate in a randomized controlled trial with two intervention protocols during four weeks (1 h per/day; 5 sessions per/week): Mirror Therapy Action Observation (MTAO) or Action Observation Therapy (AOT). The study variables will be: spontaneous use, measured with the Assisting Hand Assessment (AHA); manual ability measured with the Jebsen Taylor Hand Function Test (JTHFT); surface electromyography of the flexors and extensors muscles of the wrist and grasp strength through a grip dynamometer. Four assessments will be performed: At baseline situation, at the end of treatment, 3 and 6 months after treatment (follow-up assessments). This study will study the effects of these therapies on the use of the affected upper limb in children with hemiplegia.

Background: Inappropriate posture in children while playing some string instruments can cause back pain and alterations of the spine. To date, there is no research on the effect of exercise on children who play a musical instrument, although it is known that transversus abdominis muscle control through the Pilates method has shown pain reduction and posture improvement in this population. Objective: To assess the effectiveness of the Pilates method combined with therapeutic exercise with respect to therapeutic exercise exclusively in reducing pain and improving postural alignment in children playing string instruments applying a protocol of low dose to increase children’s adherence to training. Methods: A randomized controlled pilot study was designed with two parallel intervention groups. Twenty-five children (10–14 years old) were randomized in two intervention groups: Pilates method with therapeutic exercise (experimental) and therapeutic exercise (control) for 4 weeks (50 min per day, one day per week). Two assessments were performed (before and after treatment) to assess back pain and shoulders and hips alignment using a visual analog scale and the Kinovea program. Results: Statistically significant differences were obtained for pain reduction before (p = 0.04) and after (p = 0.01) playing the instrument in the experimental group. There were no significant changes in alignment improvement in any of the two groups. Conclusion: The application of a low dose of the Pilates method combined with therapeutic exercise could be a beneficial intervention for pain reduction before and after musical practice in children who play string instruments.
