Introduction
This study examines the biomechanical effects of the TayCo AthleticX Brace versus a standard shoe (SHOD) during landings from various heights (20, 40, and 60 cm). The study focuses on joint motion, loading patterns, and muscle activation during landings. The aim is to assess whether the AthleticX Brace effectively controls ankle motion and loading without compromising knee and hip movements, which could increase injury risk.
Methodology
Twenty young adults performed landings from three heights using three landing styles: forward with feet apart, sideways with feet apart, and sideways with feet together. Participants were tested on two separate days wearing either the AthleticX Brace or SHOD. Joint motion and loading were measured using a motion capture system and force platforms.
Key Findings
- Ankle Motion
- The AthleticX Brace effectively controlled ankle motion in all three planes (dorsiflexion/plantarflexion, eversion/inversion, and abduction/adduction) compared to the SHOD condition.
- The AthleticX Brace significantly reduced dorsiflexion and eversion, especially at higher landing heights, indicating better control of ankle motion during landings.
- Knee and Hip Motion
- There were minimal differences in knee and hip motion between the AthleticX Brace and SHOD conditions.
- The AthleticX Brace did not transfer additional strain to the knee or hip, suggesting that its use does not compromise these joints during landings.
- Joint Loading
- The AthleticX Brace reduced joint loading at the ankle, particularly in plantarflexion and external rotation.
- Small increases in abduction and internal rotation were observed, but the overall joint loads were minimal and not likely to increase injury risk.
- Muscle Activation
- Electromyographic (EMG) data showed no significant differences in muscle activity between the AthleticX Brace and SHOD, except for the gastrocnemius and soleus muscles, which activated more as landing height increased.
Conclusion
The TayCo AthleticX Brace provides superior control of ankle motion during landings from heights without increasing stress on the knee or hip joints. Its ability to reduce joint loading, especially in plantarflexion and external rotation, makes it a viable option for preventing ankle injuries during high-impact landings. Additionally, the AthleticX Brace does not negatively affect muscle activation patterns, ensuring that natural landing mechanics are maintained.
