Using the Newly Developed Floor-Sitting Movement Analysis Proforma to Study the Effect of Age and Activity on Floor-Sitting in Indian Adults.

Floor-sitting is culturally relevant to the Indian context. The present study aimed to examine the effect of age and activity on the movement patterns used and time taken to perform floor-sitting in Indian adults. Video-recordings of 30 young (23.30 ± 2.53 years) and 30 older (69.67 ± 6.45 years) adults performing floor-sitting without and with an activity (simulated feeding) were analyzed using the Floor-sitting Movement Analysis Proforma (FMAP) developed for the study. For inter-rater reliability of the FMAP, two raters analyzed the performance of a random sample of 20 participants. An almost perfect inter-rater agreeability (κ ≥ .8) was obtained for the FMAP. Cross-legged sitting was the most preferred (95%) floor-sitting position. Older adults used more number of movement components, asymmetrical patterns, more support, and more time (p < .001) as compared to the young adults. The activity facilitated the use of optimal movement strategies in young and older adults. The activity significantly increased time taken to rise from floor-sitting (p = .004). The study establishes the influence of age and activity on performance of floor-sitting. Older adults use lower developmental movement patterns that may be a "normal" adaptation to age-related sensorimotor changes. Retraining of floor-sitting is a "culturally" desired goal among Indian adults and should involve the practice of age-appropriate movement patterns in the context of meaningful activities.
