“…When compared to instrumented hip data (Bergmann et al, 2016), the EMG-assisted method predicted higher HJCF, while SO predicted lower HJCF ( (Fukumoto et al, 2013;Shih et al, 1994). Although direct comparison of muscle strength between data from Bergmann et al, (2016) and our cohort is not possible, it has been shown that muscle weakness increases with disease progression (Loureiro et al, 2013).…”

Abnormal hip joint contact forces (HJCF) are considered a primary mechanical contributor to the progression of hip osteoarthritis (OA). Compared to healthy controls, people with hip OA often present with altered muscle activation patterns and greater muscle cocontraction, both of which can influence HJCF. Neuromusculoskeletal (NMS) modelling is non-invasive approach to estimating HJCF, whereby different neural control solutions can be used to estimate muscle forces. Static optimisation, available within the popular NMS modelling software OpenSim, is a commonly used neural control solution, but may not account for an individual's unique muscle activation patterns and/or co-contraction that are often evident in pathological population. Alternatively, electromyography (EMG)-assisted neural control solutions, available within CEINMS software, have been shown to account for individual activation patterns in healthy people. Nonetheless, their application in people with hip OA, with conceivably greater levels of co-contraction, is yet to be explored. The aim of this study was to compare HJCF estimations using static optimisation (in OpenSim) and EMG-assisted (in CEINMS) neural control solutions during walking in people with hip OA. EMG-assisted neural control solution was more consistent with both EMG and joint moment data than static optimisation, and also predicted significantly higher HJCF peaks (p<0.001). The EMG-assisted neural control solution also accounted for more muscle co-contraction than static optimisation (p=0.03), which probably contributed to these higher HJCF peaks. Findings suggest that the EMG-assisted neural control solution may estimate more physiologically plausible HJCF than static optimisation in a population with high levels of cocontraction, such as hip OA.

“…Maximum voluntary bilateral hip flexion and abduction strength were measured by using a hand-held dynamometer (Isoforce GT-300, OG Giken Co. Ltd., Okayama, Japan) during isometric contraction for 3 s against manual resistance, as reported previously. 1 First, the subject rested in the supine position with the hip and knee in the neutral position for flexion/extension and for abduction/adduction. The dynamometer sensor was placed at the proximal border of the patella when assessing hip flexion, with the "lever arm" for calculation of hip flexion torque being the distance from this border of the patella to the anterior superior iliac spine.…”

“…Major muscles functioning around the hip and knee are reported to show a substantial loss of strength and mass in both patients with osteoarthritis of the hip [41] and of the knee [42]. Similarly, early postoperative strength losses and decreased functional capacity remain both post-knee replacement [43] and post-hip replacement [44] and deficits in quadriceps muscle strength have been highlighted following both procedures [21,45]. As similarities exist in atrophic musculature following hip and knee replacement surgery, these findings are important to help inform future research.…”

Purpose of Review Functional recovery from total hip replacement can be suboptimal and deficits in quadriceps muscle strength may hinder the return to activities of daily living. Neuromuscular electrical stimulation (NMES) devices have long been used to preserve and restore skeletal muscle mass and function following periods of muscle atrophy due to immobilisation. Here, we evaluate the potential role of NMES for strengthening the quadriceps muscles following hip replacement. Recent Findings Two studies have investigated the effects of NMES on quadriceps strength following hip replacement. NMES in addition to exercise training is reported to reduce length of stay and improve gait speed, stair climbing performance and sit-tostand scores in one study. Conversely, the other study reports no significant effect of NMES on length of stay or gait speed, but instead, benefits to knee extensor strength of the operated side, functional status and independence. The benefits of NMES for the treatment of atrophic musculature following knee replacement are better established. Summary Although it is not possible to offer best-practice recommendations for clinical rehabilitation, the promising approach of NMES following total hip replacement requires further investigation. When used as an adjunctive treatment to standard care physiotherapy, NMES may facilitate recovery and, when used immediately post-surgery, can enable a high exercise volume, with little effort, at a time point where muscle inhibition and atrophy are most prevalent.
