“…Functional limitations in KOA include restrictions on walking [ 10 ], ascending/descending stairs [ 11 , 12 ], bipedal squat [ 13 , 14 ] and any other weight-bearing activity on the affected limb [ 14 ], such as single-limb mini squat (SLMS). Weight-bearing asymmetry [ 13 ], muscle weakness [ 11 , 12 ], adaptative trunk position [ 15 ] and poor proprioception [ 11 ] have been observed in individuals with KOA. The SLMS is a more challenging task whereas is not possible to redistribute body weight and can reveal electromyographic (EMG), kinematic and kinetic differences [ 16 , 17 ].…”

Background The effect of hyperalgesia on functionality remains uncertain for individuals with knee osteoarthritis (KOA). This study aimed examine the clinical measures and hyperalgesia’s effect on muscle activity, knee range of motion (ROM) and postural control during the single-leg mini squat (SLMS) in individuals with KOA, determining the correlation between variables. Methods In this cross-sectional study, 60 individuals, 30 healthy (HG, 57.4 ± 6.86 years), and 30 with mild to moderate KOA (KOAG, 59.4 ± 5.46 years) were evaluated by the visual analog scale (VAS), Western Ontario and McMaster Universities Index (WOMAC), and the pressure pain threshold (PPT) in subcutaneous, myotomal, and sclerotomal structures. Muscle activity, knee ROM and postural control were assessed during a SLMS. The analyses were performed in the two phases of the SLMS. Phase 1 - during descending movement (eccentric contraction), Phase 2 - during ascending movement (concentric contraction). Analysis of covariance was applied for each variable separately, using weight as a co-variable. We used Spearman’s test for determining the correlation. Results There was no difference between groups for age, height, and postural control (p > 0.059), but KOAG presented the highest values for VAS and WOMAC (p = 0.000). In addition, EMG activity was higher in KOAG for gastrocnemius medialis and tibialis anterior muscles during phase 1 (p < 0.027), and for gastrocnemius medialis and gluteus medius muscles during phase 2 (p < 0.007), and reduced values for PPT and knee ROM (p = 0.000). Also, the correlations between PPT with muscle activity and postural control were moderate (rho< 0.482), while strong relationships were observed between some PPT points with VAS and WOMAC (rho> 0.507). Conclusion Hyperalgesia affects the functionality during a single-limb mini squat. There is an important correlation between hyperalgesia and muscle activity, postural control, and clinical measures in individuals with KOA.

“…4,5 Moreover, an inter-limb weight-bearing asymmetry is also observed as offloading mechanism on affected knee. 6 Thisincreases risk of further damage, particularly on the unaffected side. 7 For this reason, treatments of postural sway would be useful to persons with knee OA.…”

Knee joint stability is important for postural stability.Abnormal weight distribution is common in individuals with unilateral osteoarthritis of knee (OA knee) as compensatory mechanism for pain and joint malalignments. Various forms of conventional physiotherapy interventions have been used to prevent further degenerative process. Star excursion balance test (SEBT) has been invented to assess dynamic postural stability. This present study was aimed to investigate effects of SEBT as a postural control exercise training tool(SEBTx) in persons with unilateral OA knee. Fourteen participants were randomly assigned to control group (n = 7) and SEBTx group (n = 7). The control group received weekly routine physiotherapy interventions (joint mobilization, ultrasound therapy, transcutaneous electrical nerve stimulation, and taping). In addition to the routine interventions, the SEBTxgroup was instructed to perform SEBTxfor 30 min/session, 3 sessions/ week, for 4 weeks. Primary outcome (weight distributionon posturography in 8 directions -anterior, Rt. anterolateral, Rt.lateral, Rt. posterolateral, posterior, Lt. posterolateral, Lt. lateral, Lt. anterolateral)was measured at baseline and4 weeks post-intervention. Secondary outcomes numeric pain rating scale (NPRS) and Timed Up and Go test (TUG) were used to assess pain and dynamic balance, respectively. Results showed thatweight distribution inSEBTx group significantly improved in the Lt. posterolateral and posterior directions post-intervention. Moreover, NPRS in SEBTx group significantly reduced from 47.9±7.4 to 33.3±6.0. Lastly, TUG significantly reduced from 13.5±0.9 to 11.5±0.7 s in SEBTx group. In conclusion, the SEBTx should be applied to improve postural balance in individuals with unilateral (OA knee).

“…Gait asymmetry has long been known as an abnormal manifestation of individuals with neurological and musculoskeletal injuries [1] such as unilateral knee osteoarthritis (UKOA) [2]. Patients have shown a decrease in the length of the affected limb compared to that of the unaffected limb and have shown prolonged standing and single support time [3]. In addition, gait asymmetry is associated with balance disorders [4].…”

BackgroundUnbalanced standing and gait asymmetry are common in individuals with musculoskeletal disorders. Achieving symmetrical posture and gait is an important goal of rehabilitation. This study investigated the biomechanical differences in the lower extremities observed immediately after an insole was used and without the use of different one-sided insoles.Material/MethodsThirty young, healthy adult males received 3 different insole interventions: experimental group A had a customized 3-dimensional (3D)-printed single-sided lateral wedge insole (CLWI) inserted on the left side, and experimental group B had on the left side, a traditional single insert. The control had unilateral flat insoles; no insole inserted into the socks. Motion mechanics and gait parameters were collected at the 2-time points, after insertion of the insole and after 20 minutes of walking with the insole.ResultsAsymmetric posture and gait appeared immediately after using the 2 insoles (lower joint moment, P<0.05). Compared with the control group, the abnormal posture and gait of experimental group B after wearing the traditional insole for 20 minutes were not obvious (P>0.05). However, the asymmetrical posture and gait remained in experimental group A after wearing the CLWI for 20 minutes (P<0.05). The center of pressure (COP) trajectory of the left foot of experimental group A was significantly higher than that of experimental group B and the control group at the 2-time points (P<0.05).ConclusionsThe asymmetry of posture and gait can be observed in a short time using a customized 3D-printed single-sided lateral wedge insole. This experiment provides guidance for the application of customized 3D-printed single-sided lateral wedge insoles for gait rehabilitation.
