The WHO scale is designed to link a child’s growth and motor development in a single reference. The final version of the protocol included six items: unsupported sitting, hands and knees crawling, assisted standing, assisted walking, solitary standing and solitary walking. The WHO Provides important information on gross motor development in children in different cultural contexts .
The WHO Motor Development Assessment Program aims to fill existing knowledge gaps by capturing gross motor development during the first two years of life in children from different cultural backgrounds. motor development research in five countries (Ghana, Norway India Oman and United States) to analyze the relationship between physical growth and gross motor development in this culturally mixed population.
Although this study was performed on children aged 4 to 24 months, the assessment can be used in patients of different age groups and can serve as a baseline for more focused studies of motor and cognitive development . In some cases, scales are also Other Outcome Measures. An example is the Revised Hammersmith Scale (RHS), which follows the physical abilities of patients with spinal muscular atrophy .
Method of Use
WHO’s milestone assessment includes six items, which were chosen because they were considered universally fundamental and easy to test and evaluate. However, when assessing a milestone, we should not only look at what the child has done, but also how and at what level of development they are developing to do .
The six items of the WHO Milestone Scale are as follows:
- Sitting without support
- Hands and knees crawling
- Standing with assistance
- Walking with assistance
- Standing alone
- Walking alone
