However, little is known about how joint kinematics and temporal variables are affected by heel lifts. Objective: To determine the effects of heel lifts on selected lower extremity kinematic and temporal variables during the stance phase of gait in subjects with limited ankle dorsiflexion. Design: Two-way, fully repeated-measures design. The 2 factors were side (right or left) and walking condition (shoes alone, 6-mm heel lifts in shoes, 9-mm heel lifts in shoes). Setting: University biomechanics laboratory. Patients or Other Participants: Twenty-six volunteers (21 females, 5 males) with no more than 5° of ankle joint dorsiflexion. Intervention(s): Subjects were tested in shoes alone and in shoes with 6-mm and 9-mm heel lifts. Main Outcome Measure(s): We used the Qualisys Motion Analysis System to measure ankle dorsiflexion excursion, maximal knee extension, and time to heel off during the stance phase of gait under the 3 walking conditions. Results: On the right side, ankle dorsiflexion excursion increased significantly with the 6-mm and 9-mm heel lifts compared with shoes alone ( P < .05). On the left side, ankle dorsiflexion increased significantly with the 9-mm heels lifts over shoes alone and with the 9-mm heel lifts compared with the 6-mm heel lifts ( P < .05). Time to heel off increased significantly for walking with the 9-mm heel lifts compared with shoes alone ( P < .05). No differences were noted for maximal knee extension ( P > .05). Conclusions: Clinicians may consider prescribing heel lifts for patients with limited dorsiflexion range of motion if increasing ankle dorsiflexion excursion and time to heel off during the stance phase of gait may be beneficial.
