Background
Postural stability (PS) problems arise as individuals grow older, and as a result, risk of falling (RoF) increases in older adults. We sought to examine the effects of insoles of various thicknesses on PS and RoF in older adults.
Methods
Fifty-six study participants had PS and RoF evaluated statically and dynamically under five different conditions: barefoot, only-shoes, with 5-mm insoles, with 10-mm insoles, and with 15-mm insoles. Standard shoes with identical features were used. To avoid time-dependent problems, these assessments were performed under the same conditions in 3 consecutive weeks. The average of these three values was recorded.
Results
Insoles of different thicknesses significantly affected static PS (overall: P =.003; mediolateral [ML]: P =.021; anteroposterior [AP]: P =.006), static RoF (overall, ML, and AP: P < .001), dynamic RoF (overall: P = .003; ML: P = .042; AP: P = .050), and dynamic PS (overall: P = .034; AP: P = .041) but not dynamic PS ML (P = .071). For static PS overall, dynamic PS AP, static RoF overall and ML, and dynamic RoF overall and ML, the highest PS scores and the lowest RoF were recorded when using 10-mm insoles (P < .05).
Conclusions
The use of insoles of different thicknesses has been shown to be effective on all RoF and PS measurements except dynamic PS ML. The 10-mm-thick insole was a better option for elderly individuals to increase PS and reduce RoF compared. For older adults, 10-mm-thick insoles made of medium-density Plastozote may be recommended to help improve PS and reduce RoF.
Background
Any pathomechanical change in the foot or ankle is expected to cause adverse biomechanical effects on the lumbopelvic region. However, no objective data can be found in the literature regarding the effects of musculus transversus abdominis (mTrA) and musculus lumbar multifidus (mLM), which are effective muscles in lumbopelvic motor control, or regarding the extent of their effects.
Methods
Sixty-four healthy young adults were assessed by a physiotherapist (C.K.) experienced in treating feet and a radiologist (Y.D.) specialized in muscular imaging. In the determination of biomechanical properties of the foot, the navicular drop test (NDT), Foot Posture Index (FPI), pedobarographic plantar pressure analysis, and isokinetic strength dynamometer measurements were used in determining the strength of the muscles around the ankle. Ultrasonographic imaging was used to determine mTrA and mLM thicknesses.
Results
Significant correlation was found between NDT results and mTrA and mLM thicknesses (P < .05) and between FPI results and mTrA thicknesses (P < .05). As the peak pressure of the foot medial line increased, mTrA and mLM thicknesses decreased (P < .05). Although dorsiflexion muscle strength was also effective, mTrA and mLM thicknesses were found to increase especially as plantarflexion muscle strength increased (P < .05).
Conclusions
These results show that the biomechanical and musculoskeletal properties of the foot-ankle are associated with lumbopelvic stability.
Background: Losses in muscle strength, balance, and gait are common in patients with chronic stroke (CS). Ankle joint movements play a key role in this population to maintain a sufficient level of functional activity. The aim of this study was to investigate the effects of the subtalar joint (STJ) mobilization with movement (MWM) technique on muscle strength, balance, functional performance, and gait speed (GS) in patients with CS.
Methods: Twenty-eight patients with CS were randomly divided into the control group (n = 14) and the STJ MWM group (n = 14). A 30-min neurodevelopmental treatment program and talocrural joint MWM were applied to both groups. Also, STJ MWM was applied to the STJ MWM group. The patients were treated 3 days a week for 4 weeks. Ankle dorsiflexion and plantarflexion muscle strength, Berg Balance Scale, Timed Up and Go test, and GS were evaluated before and after treatment.
Results: Berg Balance Scale and Timed Up and Go test scores, dorsiflexion and plantarflexion muscle strength, and GS improved in both groups after the treatment sessions (P < .05), but the improvements were greater in the STJ MWM group compared with the control group (P < .05).
Conclusions: According to these results, STJ MWM together with neurodevelopmental treatment and talocrural joint MWM can increase ankle muscle strength, balance, functional performance, and GS on the affected leg in patients with CS.
