Influence of hip joint dysfunction on motor disorders in Japanese patients with osteoarthritis of the hip: Assessment of the JHEQ and GLFS-25 scores and hip muscle strength

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

“…In addition, its insightful application may help avert possible joint overloading and aberrant movement adaptations that can impact the limb opposite to the index side in unilateral cases and with this loadmediated pain and a diminished quality of life. [50][51][52][53] Carrying out exercise or muscle stimulation interventions or both before surgery may further foster functional outcomes as indicated by Maezawa et al 54 In particular, older patients with hip osteoarthritis are likely to benefit from continuous efforts to specifically preserve or increase their hip flexor and abductor muscle strength at all disease stages so as to maintain adequate motor function and favorable muscle physiological adaptations. 55 This applies especially to older adults who must undergo extensive hospital stays, those who have to use braces that could encourage muscle wasting, and older cases undergoing hip replacement surgery who have no signs of sarcopenia, but can yet develop this post surgery.…”

Effects of social isolation associated with the COVID-19 pandemic on hip muscle strength, hip joint pain, and walking ability in patients with osteoarthritis of the hip joint

“…On the other hand, hip abduction muscle strength decreased during the COVID-19 pandemic in few patients in both the post-THA and the severe-OA group. As knee extension muscle strength are important for maintaining physical activity in older adults and other people with osteoarthritis of the hip joint, 5 , 6 , 7 , 8 , 9 staying at home during the COVID-19 pandemic may have adversely affected patients with severe hip OA. Moreover, in the severe-OA group, pain worsened to mild or moderate from before to during the pandemic in more patients and the percentage of patients who could walk continuously for only about 5 minutes increased from 17.9 % to 29.8 % during the pandemic.…”

“…Generally, total hip arthroplasty (THA) is performed to relieve symptoms in patients with severe hip OA, and after THA, patients are able to regain mobility similar to that of a healthy person of equivalent age. 5 However, no studies have examined the effects of the COVID-19 pandemic on walking ability and lower extremity muscle strength in patients after THA. In older adults and other people with OA of the hip joint, knee extension muscle strength is important for maintaining physical activity.…”

“…In older adults and other people with OA of the hip joint, knee extension muscle strength is important for maintaining physical activity. 5 , 6 , 7 , 8 , 9 Although past studies investigated the effects of social isolation, such as lock down, on lower limb muscle strength by interviewing participants, none measured the actual changes in lower limb muscle strength.…”

Changes in serum creatine kinase and C-reactive protein after posterior and direct anterior approaches in total hip arthroplasty

“…[18][19][20][21] In our previous study, we also found a significant difference in straight leg-raise strength (1 of the indicators of quadriceps strength) between patients with low and high locomotive function after total hip arthroplasty. 22 Although postoperative straight leg-raise strength is important for a patient's activities of daily living and quality of life, it has received little attention in previous studies. In a rare, valuable study, Cheng et al 23 reported that straight leg-raise strength in the supine position was significantly lower in the DAA group than in the PA group.…”
