“…Muscular strength was similar between the groups, indicating that irrespective of the approach used, the traumatization of muscles during surgery results in clinically relevant reduction in muscle strength, even 3 months after surgery. Regaining of equal bilateral muscle strength postoperatively is important in achieving a normal gait pattern without limping (Suter et al 1998, Johnston et al 2007, Talis et al 2008, Tsai et al 2015). Overloading of the unoperated hip might also increase the risk of developing osteoarthritis in the healthy leg (Suter et al 1998, Talis et al 2008).…”

Background and purposeMinimizing the decrease in muscular strength after total hip arthroplasty (THA) might allow patients to recover faster. We evaluated muscular strength in patients who were operated on using 3 surgical approaches.Patients and methodsIn a prospective cohort study, 60 patients scheduled for primary THA were allocated to the direct lateral, posterior, or anterior approach. Leg press and abduction strength were evaluated 2 weeks or less preoperatively, 2 and 8 days postoperatively, and at 6-week and 3-month follow-up.ResultsDifferences in maximal strength change were greatest after 2 and 8 days. The posterior and anterior approaches produced less decrease in muscular strength than the direct lateral approach. 6 weeks postoperatively, the posterior approach produced greater increase in muscular strength than the direct lateral approach, and resulted in a greater increase in abduction strength than the anterior approach. At 3-month follow-up, no statistically significant differences between the groups were found. The operated legs were 18% weaker in leg press and 15% weaker in abduction than the unoperated legs, and the results were similar between groups.InterpretationThe posterior and anterior approaches appeared to have the least negative effect on abduction and leg press muscular strength in the first postoperative week; the posterior approach had the least negative effect, even up to 6 weeks postoperatively. THA patients have reduced muscle strength in the operated leg (compared to the unoperated leg) 3 months after surgery.

“…The positions of the two DWSs were marked with tape on the floor to ensure the same placement. Participants were asked to stand with bare feet placed centrally on each DWS to ensure even weight distribution on load cells and were instructed to stand with feet placed shoulder-width apart [18] with their hands at their sides [1]. They were instructed to look straight ahead [19] throughout their stance on the DWSs.…”

“…Limb loading distribution is said to be symmetrical when both lower limbs load equally. Functional activities such as standing and walking are said to be energy efficient when both lower limbs behave symmetrical in loading [1,7]. However, unequal limb loading in the long term may lead to complications such as osteopenia, cartilage destruction, and joint degeneration [6][7].…”

“…The ability to maintain the body in equilibrium during standing is influenced by factors such as visual input and lower-limb weight distribution [2][3][4]. The presence of visual input improves postural control in standing [1]. On the other hand, eyes closed (EC) during standing produces a greater body sway, resulting in postural instability leading to asymmetrical limb loading [3,5].…”

Abstract-Limb loading measurements serve as an objective evaluation of asymmetrical weight bearing in the lower limb. Digital weighing scales (DWSs) could be used in clinical settings for measurement of static limb loading. However, ambiguity exists whether limb loading measurements of DWSs are comparable with a standard tool such as MatScan. A crosssectional study composed of 33 nondisabled participants was conducted to investigate the reliability, agreement, and validity of DWSs with MatScan in static standing. Amounts of weight distribution and plantar pressure on the individual lower limb were measured using two DWSs (A, B) and MatScan during eyes open (EO) and eyes closed (EC) conditions. The results showed that intra-and interrater reliability (3, 1) were excellent (0.94-0.97) within and between DWS A and B. Bland-Altman plot revealed good agreement between DWS and MatScan in EO and EC conditions. The area under the receiver operating characteristic curve was significant and identified as 0.68 (p = 0.01). The measurements obtained with DWSs are valid and in agreement with MatScan measurements. Hence, DWSs could be used interchangeably with MatScan and could provide clinicians an objective measurement of limb loading suitable for clinical settings.

Total hip arthroplasty (THA) is a common surgical procedure for patients suffering from osteoarthritis to relieve their pain and to attempt to restore their normal locomotion patterns. Although this procedure does not restore normal mobility during activities of daily living, it remains unclear how it affects the joint mechanics of both lower limbs during stair negotiation tasks. Hence, we compared the 3D joint mechanics of both lower limbs of THA patients with matched healthy controls during stair ascent and stair descent. 3D kinematics and kinetics of both lower limbs were recorded for 20 patients having undergone unilateral THA and 20 healthy, age and body mass index matched control participants. The THA patients generated limited power at the operated hip joint, and thus compensated with larger power generation at the contralateral ankle to lift the body weight to the next step. This stair ambulation strategy, as well as others, adopted by the THA patients implied decreased activation of the lower limb musculature, which may be indicative of a muscle strength deficiency or a post-operatively adopted protective mechanism to unload the prosthesis. These asymmetric power production patterns should be addressed in rehabilitation programs pre-and post-operatively. ß
