A kinetic wedge is a physical therapy technique used to correct movement patterns and improve biomechanics during rehabilitation, utilizing controlled movements or exercises to guide the body into proper alignment through active motion. This approach is particularly effective for addressing movement dysfunctions because it trains the neuromuscular system to maintain correct positioning during functional activities. The concept of a kinetic wedge is closely related to the management of conditions such as functional hallux limitus, where the first metatarsophalangeal joint's inability to dorsiflex during gait can lead to abnormal foot and postural biomechanics, causing chronic postural pain 1. Recent studies have shown that the use of novel forefoot orthoses can significantly improve foot function, reduce pain, and restore physiologic stance in patients with symptomatic hallux limitus, with 94.7% of participants experiencing improvements in foot function and pain, and 63.2% reporting complete resolution of pain 2. Key aspects of kinetic wedges include:
- Utilizing active motion rather than passive positioning to achieve proper joint alignment and muscle recruitment
- Training the neuromuscular system to maintain correct positioning during functional activities
- Effectiveness in treating conditions like patellofemoral pain syndrome, shoulder impingement, and lower back pain by retraining movement patterns that contribute to these problems
- Application of the principle of motor learning to create lasting neurological adaptations that carry over into daily activities. Overall, the kinetic wedge technique offers a valuable approach to addressing movement dysfunctions and improving biomechanics, with recent evidence supporting its effectiveness in managing conditions such as hallux limitus 2.
