Effect of a 6-week dynamic neuromuscular training programme on ankle joint function: A Case report

Area of Science:

• Sports Medicine
• Rehabilitation Science
• Biomechanics

Background:

• Chronic ankle instability (CAI) often follows ankle sprains, impacting athletes and requiring effective rehabilitation.
• Dynamic neuromuscular training is increasingly recommended to improve sensorimotor function after ankle sprains.
• Limited research exists on dynamic neuromuscular training's effect on ankle positioning during jump landings, a key injury mechanism.

Purpose of the Study:

• To investigate the effects of a 6-week dynamic neuromuscular training program on ankle joint function in an athlete diagnosed with CAI.
• To assess changes in ankle joint positioning and stability during landing tasks post-intervention.

Main Methods:

• A 6-week progressive dynamic neuromuscular training program including postural stability, strengthening, plyometrics, and speed/agility drills.
• Outcome measures included the Cumberland Ankle Instability Tool (CAIT) and Star Excursion Balance Test (SEBT) for instability and balance.
• Ankle joint plantar flexion during drop landings and ground reaction forces (GRFs) during walking were analyzed.

Main Results:

• Significant improvements were observed in CAIT and SEBT scores, indicating enhanced ankle stability and balance.
• A reduced angle of ankle plantar flexion at initial contact during drop landing and vertical jumping was noted, suggesting a less vulnerable landing position.
• Post-intervention, ground reaction forces during walking were reduced, indicating improved biomechanical efficiency.

Conclusions:

• A 6-week dynamic neuromuscular training program effectively improved sensorimotor control parameters in an athlete with CAI.
• The findings suggest potential benefits for reducing injury risk factors associated with CAI.
• Further research with larger sample sizes is warranted to confirm these effects on ankle injury risk.
