Purpose: The purpose of this study was to determine the appropriateness of TGMD-3 for children with visual impairments.
Population: 66 children/adolescents between ages 9-18 y/o attending a sports camp for children with visual impairments.
Methods: Measures included the TGMD-2, which provides results that are both valid and reliable for children with and without visual impairments, and TGMD-3, which currently does not have existing norms. Both assess locomotor skills through: run, hop, slide, gallop, and skip, leap and jump. Both assess object control skills through: throw, underhand throw, roll, catch, kick, one-hand strike, 2-hand strike, and dribble. A team of researchers provided modifications when necessary during this study. 2 forms of reliability were assessed: internal consistency and inter rater reliability.
Results: this study concluded that TGMD-3 has high internal consistency and strong interrater reliability when used with children with visual impairments, indicating it can appropriately be used for this population to assess gross motor development.
Strengths: Varied developmental ages of participants.
Limitations: visually impaired children may not have modifications available to fully participate with their peers in activity, even if motor skills are there, and may be at increased risk of injury.
Conclusions: TGMD-3 has high internal consistency and strong interrater reliability for children who are visually impaired, and is appropriate to use for this population.

This is good to know that the TGMD-3 may be used for children with visual impairments, and I like that you point out that it still may mean that children who are visually impaired may still experience participation limitations with their peers regardless of motor skill abilities.
