Walking energetics and abductor strength are associated with physical activity in older women with hip osteoarthritis

Sarcopenia and hip osteoarthritis: possible role for targeted electrical and biophysical muscle stimulation applications

“…33 There may also be a strong rationale for quadriceps muscle stimulation in hip osteoarthritis as outlined by Fukumoto et al 34 and Ikutoma et al 35 Other forms of biophysical stimulation that can enhance muscle composition such as pulsed electromagnetic field therapy may also prove effective for minimizing osteoarthritis disability, or for slowing any associated adverse muscular impacts on the diseased joint, [36][37][38] as well as favorably impacting nerve damage that may underpin atrophic muscle states that are found to limit physical activity participation in older hip osteoarthritis cases with weak hip abductors or signs of accelerated muscle aging. [39][40][41] Some of these benefits may be due to the ability of certain forms of electrical stimuli to selectively target and strengthen certain muscles, improve muscle function, and to carefully modify the behaviors of intrinsic muscle fibers by increasing the contraction load per day. 41 More recently, Leon-Salas et al 42 developed a stimulator that was said to generate pulsing electric and magnetic fields at programmable rates and intensities to target bone and muscle tissue simultaneously with the aim of improving the therapeutic treatment of osteoporosis-a condition that might be implicated in some cases of hip osteoarthritisand sarcopenia -or both conditions.…”
