Overview
Total knee arthroplasty (TKA) is a common surgery used to treat advanced knee osteoarthritis, especially when other treatments no longer help. While the surgery often reduces pain and improves joint alignment, many patients still have problems with balance and movement afterward.
This study will explore whether adding balance training using the Tecnobody ProKin system to standard physical therapy helps patients recover better after TKA. The researchers will measure balance, walking ability, leg strength, and body awareness (also called proprioception) using special equipment.
The main goal is to test the hypothesis that technology-supported balance training improves recovery outcomes more effectively than standard rehabilitation alone.
Description
Knee osteoarthritis is a prevalent condition among older adults, often leading to pain, reduced mobility, and functional limitations. When conservative treatments fail to provide adequate relief, total knee arthroplasty (TKA) is commonly performed. Although outcomes following TKA are generally satisfactory, patients may continue to experience impairments in proprioception and balance, which can negatively affect gait and postural control.
Restoring balance and proprioceptive function is critical for optimizing functional recovery and quality of life after TKA. However, research shows that many patients fail to fully regain these abilities, even in the long term. Instrumented platforms are frequently used to objectively assess balance and proprioception, providing detailed parameters based on body sway during standing tasks.
Previous studies have evaluated the effects of balance training using systems such as Biodex in TKA patients. However, no study has yet investigated the use of the Tecnobody ProKin dynamometric platform (Bergamo, Italy) to assess and train static and dynamic balance, proprioception, muscle strength, and gait within a controlled rehabilitation framework.
This study is designed to generate scientific evidence on the effectiveness of balance training using the Tecnobody ProKin platform as an adjunct to standard rehabilitation in patients following total knee arthroplasty.
