Bottom Line: A significantly larger range of internal/external rotation and inversion/eversion motion was observed in the subtalar joint of MTSS patients compared to healthy controls (P < 0.05) from heel contact to heel off.Our results indicate that the range of subtalar joint motion is greater in patients with MTSS during the stance phase of the forward step.The kinematic results obtained of this study may have important clinical implications and add quantitative data to an in vivo database of MTSS patients.

ABSTRACT

Background: The rearfoot motion during sports activities in patients with the medial tibial stress syndrome (MTSS) is unknown. This study aimed to investigate the difference in kinematics of the rearfoot in MTSS patients (eight male soccer players) and control participants (eight male soccer players) during a forward step.

Methods: Sixteen male soccer players, including eight players with MTSS, participated. Forward step trials were recorded with cineradiographic images obtained at a sampling rate of 60 Hz. Geometric bone models of the tibia and talus/calcaneus were created from computed tomography scans of the distal part of one lower limb. Following a combination of approaches, anatomical coordinate systems were embedded in each bone model. The talocrural joint motion (relative motion of the talus with respect to the tibia) and subtalar joint motion (relative motion of the calcaneus with respect to the talus) were examined.

Results: A significantly larger range of internal/external rotation and inversion/eversion motion was observed in the subtalar joint of MTSS patients compared to healthy controls (P < 0.05) from heel contact to heel off. There were no significant differences between the MTSS patients and healthy participants in the ranges of all talocrural joint angles during the forward step.

Conclusion: Our results indicate that the range of subtalar joint motion is greater in patients with MTSS during the stance phase of the forward step. The kinematic results obtained of this study may have important clinical implications and add quantitative data to an in vivo database of MTSS patients.

Mentions: To investigate rearfoot movement during the stance phase of the forward step, we recorded forward step trials on a platform (Fig. 1). Participants first stood straight with both feet together to record the static lower extremity position (relaxed neutral standing position with knees straight). The participants then ran with a normal stride, with the second toe of the foot and heel contacting a line parallel to the direction of movement. We confirmed that the foot was parallel to the tape (parallel to direction of the movement) on the platform during all data collection. During the participants first step, we recorded the foot (right foot of healthy participants, foot corresponding to the side of MTSS) that was grounded (i.e., when one foot contacted the platform, the other foot was off the platform). The forward step pitch was set at 2.5 steps/s using a metronome. Each forward step trial was recorded using cineradiography (Infinix Celeve-l INFX-8000C, Toshiba Medical Inc., Tochigi-ken, Japan). Acquired orthogonal images squared the foot and the central ray. Eight inch square images were obtained at 60 frames/s, with an expected radiation exposure equivalent of 200 mA (1 ms) with an intensity of 50 kV, expected 15 mGy.Fig. 1
