Article Synopsis
  • - Cerebral palsy (CP) can cause crouch gait due to tight hamstrings, leading to the need for surgical procedures like hamstring lengthening, with new methods like percutaneous techniques emerging as options.
  • - A study compared two types of hamstring lengthening surgeries (percutaneous vs. open) in children with spastic diplegic CP, focusing on their impact on gait and knee function.
  • - Results showed that both methods significantly improved patient outcomes, with no major differences between them, indicating that percutaneous hamstring lengthening is a safe and effective alternative to traditional surgery.

Seasonality and volatility of vegetation in the ecosystem are associated with climatic sensitivity, which can have severe consequences for the environment as well as on the social and economic well-being of the nation. Monitoring and forecasting vegetation growth patterns in ecosystems significantly rely on remotely sensed vegetation indices, such as Normalized Difference Vegetation Index (NDVI). A novel integration of the Generalized Autoregressive Conditional Heteroskedasticity (GARCH) and the Holt-Winters (H-W) models was used to simulate the seasonality and volatility of the three different agro-climatic zones in Jharkhand, India: the central north-eastern, eastern, and south-eastern agro-climatic zones.
