Force Attenuation Properties of Padded Dance Support Socks

Area of Science:

• Biomechanics
• Dance Science
• Sports Medicine

Background:

• Foot injuries are prevalent in dancers, particularly in modern and contemporary styles where footwear is absent.
• Padded dance socks are a potential protective measure, but their efficacy in reducing foot impact forces remains unquantified.
• Existing research on dance injury prevention has largely focused on ballet.

Purpose of the Study:

• To investigate the force-reducing effects of padded dance support socks during a modern dance sequence.
• To quantify the impact of padded dance socks on force reduction during sauté jump landings.
• To compare biomechanical forces experienced by dancers wearing padded socks versus those dancing barefoot.

Main Methods:

• A randomized, cross-over study involving 21 injury-free dancers performing a modern dance sequence and sauté jumps.
• Force transducers measured forces under the metatarsophalangeal joint and heel, while a force platform recorded vertical ground reaction forces.
• Data were collected both with padded dance socks (DS) and barefoot (BF), with all force data normalized to body weight (BW).

Main Results:

• Padded dance socks (DS) significantly reduced mean and peak heel forces during the dance sequence compared to barefoot (BF) conditions.
• Peak vertical ground reaction forces (VGRF) during sauté jump landings were significantly lower when wearing DS compared to BF.
• While other measured forces showed a trend towards reduction with DS, statistical significance was not reached for all variables.

Conclusions:

• Padded dance socks demonstrate potential for reducing foot forces experienced by modern dancers during performance and jumping.
• The observed force reductions suggest a possible benefit in mitigating the cumulative impact on dancers' feet.
• Further investigation is warranted to fully assess the long-term protective effects of padded dance socks considering training volume and cumulative impact.
