Preliminary investigation of residual limb plantarflexion and dorsiflexion muscle activity during treadmill walking for trans-tibial amputees.
Novel powered prosthetic ankles currently incorporate finite state control, using kinematic and kinetic sensors to differentiate stance and swing phases/sub-phases and control joint impedance and position or torque. For more intuitive control, myoelectric control of the ankle using the remnant residual limb dorsiflexors and plantarflexors, perhaps in concert with kinetic and kinematic sensors, may be possible. ⋯ These observations demonstrate the potential for future myoelectric control of active prosthetic ankles. Clinical relevance This study demonstrated the feasibility of applying upper extremity prosthetic myoelectric signal acquisition, processing and control techniques to future myoelectric control of active prosthetic ankles for trans-tibial amputees.

Clinical TrialEffect of load carriage on chronic low back pain in adults with cerebral palsy.
Chronic low back pain (LBP) is a common secondary musculoskeletal problem among adults with cerebral palsy (CP). This study investigated the feasibility of incorporating backpack carriage with daily production activities for relieving chronic LBP among adults with CP. ⋯ The loaded backpack has the potential to serve as an 'orthosis' for immediate back pain relief among adults with CP. Its underlying mechanism can be attributed to a reduction in back muscle tension during the load carriage.

Is hip muscle strength the key to walking as a bilateral amputee, whatever the level of the amputations?
Little data have been reported on the factors that are important in bilateral amputee walking ability especially the role of hip strength. ⋯ Bilateral amputee walking ability was reduced and mainly related to level of amputation. The role of hip strength in bilateral amputee walking ability requires further investigation.

ReviewSystematic review of concepts measured in individuals with lower limb amputation using the International Classification of Functioning, Disability and Health as a reference.
The International Classification of Functioning, Disability and Health (ICF) is comprehensive but difficult to use in clinical practice. ICF Core Sets are one method of increasing the use of the ICF in clinical practice. To develop a condition-specific core set requires identification of the concepts measured in current clinical practice. ⋯ The ICF is available in over 25 languages. Improving the usefulness of the classification for clinicians will assist in standardising clinical practice and in comparison of outcomes nationally and internationally. ICF Core Sets are designed to use a manageable number of categories from the ICF to allow application in day-to-day clinical practice.

Patient satisfaction following lower-limb amputation: the role of gait deviation.
Patient satisfaction is an important measurement in healthcare for administrators, clinicians and patients. ⋯ For the high functioning individuals with lower-limb amputation in this study, gait deviation was not a significant correlate of patient satisfaction. RESULTS suggest that improving self-perceived functional ability and attitudes toward the prosthesis, rather than minimizing gait deviation, will improve patient satisfaction.
