“…Since our focus is on muscle control compensations, such kinematic differences between treadmill and overground would not appear to influence on our results. Previous modeling studies have performed similar analyses of compensatory mechanisms [30,31], but no study has analyzed the entire gait cycle. Jonkers et al [30] used forward dynamics simulations and optimization to determine compensatory strategies present in the stance phase of gait as a result of the exclusion of SOL, GAS, HAM and GMAX.…”

“…Similar to the present study, they found that HAM and GMAX played an important role in compensating for one another as well as SOL and GAS, but that other compensations were necessary to completely compensate for the deactivation of these muscles. Komura et al [31] used an inverse dynamics-based analysis and static optimization to examine the interactions of 13 lower extremity muscles during the stance phase of gait by systematically deactivating each muscle, which produced similar results to those of Jonkers et al [30]. The results of our study build upon these previous analyses by examining the muscle mechanical energetics and compensatory mechanisms over the entire gait cycle associated with the clinically relevant impairments of reduced strength in specific muscle groups and increased hip joint stiffness.…”

“…Ankle plantarflexor and hip flexor strategies would play complementary roles in swing initiation [17]. Indeed, a simulation study has shown that deactivation of the iliopsoas muscle increases the muscle force exerted by the gastrocnemius muscle during gait, and vice versa [18]. In the current study, because of the redistribution of muscle power by the walking exercise with decreased ankle pushoff, patients with THA would produce increased power of the hip flexors relative to the ankle plantarflexors.…”

Residual hip impairments, such as decreased hip muscle moment and power during walking, have been reported in patients with total hip arthroplasty (THA). Meanwhile, greater ankle power has also been reported in these patients. We investigated the interaction between hip and ankle joints during walking to determine the effects of different ankle pushoff instructions on hip biomechanics in patients with THA. Twenty-four women (age, 60.8±5.5 years) were randomly assigned to walking exercise groups with either decreased pushoff or increased pushoff. Patients in the decreased pushoff group and increased pushoff group were given the instructions "push less with your foot when you walk" and "push more with your foot when you walk," respectively. Exercises lasted approximately 10-15 min. A series of gait-related parameters were analyzed during pre-exercise, exercise, and post-exercise session. In the decreased ankle pushoff group, hip flexor power absorption and hip/ankle power ratio were higher during post-exercise than during pre-exercise. An increase in hip power from -9.8% to 32.1% was identified. The effect of increase in the hip power by the decreasing ankle pushoff was higher in the patients with greater ankle pushoff in their natural gaits. The patients in the increased ankle pushoff group showed decreased hip flexion angle and hip muscle moment and power after the walking exercise, although ankle pushoff was not increased. Walking exercise with decreased ankle pushoff may help improve the distribution of muscle power between hip flexors and ankle plantarflexors during walking in patients with THA.

“…Moreover, the deactivation of the iliopsoas muscle can affect the impact on the ankle joint and force production of the triceps surae, as observed in a biomechanical study that evaluated the impact of muscle deactivation on the musculoskeletal system during gait motion. 21 Wainner et al 22 described the concept of regional interdependence, where seemingly unrelated impairments in a remote anatomical region may contribute to, or be associated with, the primary complaint of the patient.…”

Objective: The purpose of this case report is to describe the management of using a combination of hip strengthening and manipulative therapy (MT) for a patient with plantar fasciitis. Clinical Features: A 44-year-old patient reported heel pain for approximately 1 year before treatment. The patient reported plantar heel pain and tenderness at the calcaneal tuberosity. The pain was most noticeable in the morning but was reduced after a 30-minute walk. A diagnosis of plantar fasciitis was made at the initial assessment. Intervention and Outcomes: Initially, a clinical evaluation was performed to measure pain intensity (Numeric Pain Rating Scale), pressure-pain threshold (algometry), and perceived exertion (OMNI Resistance Exercise Scale). The patient then underwent 10 sessions of hip strengthening and MT over a period of 3 months. After the treatment, the intensity of pain and the pressure-pain threshold was reevaluated. The patient reported an improvement in pain intensity (baseline score = 6 vs final score = 1) and an increase in the pressure-pain threshold (initial score = 2.6 vs final score = 7.1). Perceived exertion was also improved after hip muscle strength training (initial score = 10 vs final score = 8). Conclusion: The combination of hip strengthening and MT improved foot pain in a patient with a clinical diagnosis of plantar fasciitis. (J Chiropr Med 2016;15:310-313)
