The influence of motion control shoes on the running gait of mature and young females

Gait & Posture; Article in Press

Background
This study compared the running gait of mature and young females, and investigated the effect of a motion control shoe. First, it was hypothesised that in a neutral shoe, mature females would display significantly greater rearfoot eversion, knee internal rotation and external adductor moments when compared to a younger group. Secondly, the motion control shoe would reduce rearfoot eversion and knee internal rotation in both groups. Thirdly it was hypothesised that the motion control shoe would increase knee external adductor moment, through an increase in knee varus and moment arm.

Methods
15 mature (40–60 years) and 15 young (18–25 years) females performed 10 running trials at 3.5ms−1±5% over a force platform. Two shoes were tested, the Adidas Supernova Glide (neutral), and the Adidas Supernova Sequence (motion control). Ankle and knee joint dynamics were analysed for the right leg, and the mean of ten trials was calculated. Joint moments were calculated using inverse dynamics.

Findings
In the neutral condition, mature females presented greater peak rearfoot eversion, knee internal rotation, and external adductor moments than young females (p<0.05). A motion control shoe significantly reduced peak rearfoot eversion and knee internal rotation among both groups (p<0.05). No between shoe differences in knee external adductor moment were observed.

Interpretation
A motion control shoe is recommended to reduce risk of injury associated with rearfoot eversion and knee internal rotation in mature females. However since the knee external adductor moment is a variable commonly associated with medial knee loading it is suggested that alternative design features are required to influence this moment.

Highlights
► The running gait of mature females gait could predispose to injuries.
► We examined effect of motion control shoes on running gait of mature females.
► Motion control shoes reduce rearfoot eversion and knee internal rotation.
► Motion control shoes do not affect knee external adductor moment.
► Mature females should run with insoles with both medial and lateral support.

Influence of Motion Control Shoes on the Lower Extremity Three
Dimensional Joint Moments during Running in Females with
Patellofemoral Pain Syndrome
Fatemeh Salari-Esker et al
J Rehab Med. 2019; 8(3): 42-50

Background and Aims: Footwears are routinely used with the belief that they have a direct effect on
the knee. Excessive pronation of the subtalar joint with associated internal rotation of the tibia relative
to the femur has been postulated to be a causative factor of patellofemoral pain syndrome (PFPS).
Motion control shoes aim to reduce excessive rearfoot motion and lead to reduction of internal
rotation of tibia. The aim of the present study was to evaluate the effect of motion control shoes on the
three dimensional lower limb joint moments during running in patellofemoral pain syndrome females.
Materials and Methods: A total of 20 females with PFPS performed 5 running trials at 3 ±0.2 m/s
speed. Two shoes were tested: the Nike free 5 shoe (control)، and the Asics GEL-Kayano 21 (motion
control). Joint moments calculation was carried out using invers dynamic equations. Also, betweencondition comparisons were assessed running paired T-test (P≤0.05).
Results: A motion control shoe significantly reduced peak ankle adductor moment (p=0.038)،
increased external rotator (p=0.001), and decreased abductor knee joint moments (p=0.024). In the hip
joint، adductor moment was decreased (p=0.005) and the external rotator moment was increased
(p=0.001) using motion control shoe. No differences were observed in sagittal plane lower limb joint
moments between the two shoes.
Conclusion: The results of our study indicated that a motion control shoe can control the subtalar
joint pronation by decreasing the amount of adductor moment and increasing peak of the inversion
angle during running. The effectiveness of these shoes in frontal and horizontal planes is high as they
seem to control the rearfoot movement in these planes. These results indicate that the motion control
shoes as an efficient and nonsurgical prevention must be considered for PFPS.
