چکیده انگلیسی
Toe-in and toe-out gait modification has received attention lately as a promising treatment for knee osteoarthritis due to its potential to improve knee joint loading and pain. However, the neuromuscular patterns associated with these walking styles are not well known, a factor that may influence knee joint load itself. Our aim was to conduct a thorough examination of the neuromuscular patterns associated with toe-in and toe-out walking in people with knee osteoarthritis. Fifteen participants were instructed to walk in four different foot rotations: 10° toe-in, 0°, as well as 10° and 20° toe-out. Nine surface electrodes were placed over lower extremity muscles and a variety of muscle activation parameters were examined. Peak and average medial hamstrings muscle activation was increased (pâ¯=â¯0.001, pâ¯<â¯0.001) during toe-in walking compared to toe-out walking. As well, average lateral gastrocnemius muscle activation was higher (pâ¯=â¯0.001) during toe-in walking compared to 20° toe-out. Medial thigh muscle co-contraction was higher (pâ¯=â¯0.003) during toe-in walking compared to all other conditions, and medial to lateral gastrocnemius activation ratio was lower (pâ¯=â¯0.032) during toe-in walking. These findings suggest potential overall increased joint loading with toe-in walking as a result of muscle co-contraction. Long-term assessment of these strategies is warranted.
