Assessing the forces between the foot and the ground is a key part of many biomechanical analyses of locomotion. Studying these loading patterns can help us to understand how the forces are transferred to the tissues of the body. These forces are essential for maintaining the health of tissues, but if they are too high they can lead to damage and i...

Subtalar arthroereises (STA) is a minimally invasive and reversible surgery to correct symptomatic flexible flatfoot (FFF) in children. Various techniques were described either applying expandable sinus tarsi implants or lateral calcaneus stop screws. Studies comparing the outcome of STA with different devices are rare. This retrospective single-ce...

Background: For demanding activities in daily life, such as negotiating stairs, ramps and uneven ground, the functionality of conventional prosthetic feet (“Daily Life Feet” - DLF) is often limited. With the introduction of microprocessor-controlled feet (MPF) it was expected that the functional limitations of DLF might be reduced. The purpose of t...

Background: Knee osteoarthritis (KOA) is the most common form of arthritis with an estimated lifetime prevalence of 45%. The use of orthotic devices is a generally accepted conservative therapy in KOA. A new conservative treatment is an ankle-foot orthosis (AFO); however, studies on the biomechanical effects are limited. The aim of this study was...

Background: Subjective data and physical examinations of patients after total hip arthroplasty are used to assess the outcome.

Background: Knee osteoarthritis (KOA) is a painful disease commonly caused by high loads on the articular cartilage. Orthotic interventions aim to reduce mechanical loading, thereby alleviating pain. Traditional orthotics appear effective, but high drop-out rates have been reported over prolonged periods. Research question: The aim of this study...

Background: Knee osteoarthritis patients may become physically inactive due to pain and functional limitations. Whether physical activity exerts a protective or harmful effect depends on the frequency, intensity, time and type (F.I.T.T.). The F.I.T.T. dimensions should therefore be assessed during daily life, which so far has hardly been feasible....

The foot sole is loaded during stance and gait and plantar cutaneous mechanoreceptors sense the local stress distribution. It is not clear whether the perception thresholds of these mechanoreceptors change during the day and how they respond to walking activities. The primary aim of the present study was to investigate diurnal changes of plantar se...

Everyone's walking style is unique, and it has been shown that both humans and computers are very good at recognizing known gait patterns. It is therefore unsurprising that dynamic foot pressure patterns, which indirectly reflect the accelerations of all body parts, are also unique, and that previous studies have achieved moderate-to-high classific...

The plantar surface of the foot senses local pressures during stance and locomotion. These foot loading characteristics may be affected by long distance running. Little is known about the physiological effects of sports-related loading on plantar sensitivity and their relationship with plantar foot loading. The purpose of this study was to investig...
