Symptoms of peripheral neuropathy. The main symptoms of peripheral neuropathy can include: numbness and tingling in the feet or hands. burning, stabbing or shooting pain in affected areas. loss of balance and co-ordination. muscle weakness, especially in the feet. These symptoms are usually constant, but may come and go.

- Function of The Foot
The foot and ankle form a complex system which consists of 28 bones, 33 joints, 112 ligaments, controlled by 13 extrinsic and 21 intrinsic muscles. The foot is subdivided into the rearfoot, midfoot, and forefoot. It functions as a rigid structure for weight bearing and it can also function as a flexible structure to conform to uneven terrain. The f...
Talocrural Joint
The tip of the medial malleoli is anterior and superior to the lateral malleoli, which makes its axis oblique to both the sagittal and frontal planes. The axis of rotation is approximately 13°-18° laterally from the frontal plane and at angle of 8°-10° from the transverse plane. Motion in other planes is required (like horizontal and frontal plane) to achieve a complete motion for plantarflexion and dorsiflexion. The reported normal available range for dorsiflexion varies in the literature be...
Subtalar Joint
The axis of the subtalar joint lies about 42° superiorly to the sagittal plane and about 16° to 23° medial to the transverse plane. The literature presents vast ranges of subtalar motion ranging from 5° to 65°. The average ROM for pronation is 5° and 20° for supination. Inversion and eversion ROM has been identified as 30° and 18°, respectively.Total inversion-eversion motion is about 2:1 and a 3:2 ratio of inversion-to-eversion movement.
Midtarsal Joint
The Midtarsal joint rotates at two axes due to its anatomy, making its motion complex. The longitudinal axis (image 'A' below) lies about 15° superior to the horizontal plane and about 10° medial to the longitudinal plane. The oblique axis (image 'B' below) lies about 52° superior to the horizontal plane and 57° from the midline. The longitudinal axis is close to the subtalar joint axis and the oblique axis is similar to the talocrural joint axis.
Arthrokinematicsrefers to the movement of joint surfaces. 1. Talocrural Joint– The talus rolls within the mortise during dorsiflexion and plantarflexion. During dorsiflexion, the talus rolls anteriorly and it glides posteriorly. While with plantarflexion, the talus rolls posteriorly and glides anteriorly. 2. Subtalar Joint – Secondary to the anatom...
Gaitis made up of repetitive cycles of the stance phase when the foot is on the ground (foot strike, mid stance, and terminal stance) and the swing phase when the foot is in the air. When running, there is an additional phase: the float phase when both feet are off the ground. 1. During walking, In foot strike, the foot is supinated, and Chopart jo...
As discussed above with MT joint locking, the transition in the foot from pronation to supination is an important function that assists in adapting to uneven terrain and acting as a rigid lever during push off. 1. During pronation, the MT joint unlocks, providing flexibility of the foot and assisting in maintaining balance. 2. During supination, th...
The arches of the foot provide functions of force absorption, base of support and acts as a rigid lever during gait propulsion. The medial longitudinal arch, lateral longitudinal arch and transverse arch are the 3 arches that compromise arches of foot.
The foot requires sufficient mobility and stability for all of its functions. Mobility is necessary for absorbing the ground reaction force of the body. Subtalar pronation has a shock absorbing effect during initial heel contact. Pronation is also necessary to enable rotation of the leg and to absorb the impact of this rotation. Subtalar pronation ...
A solid understanding of anatomy is essential to effectively diagnose and treat patients with foot and ankle problems. Anatomy is a road map. Most structures in the foot are fairly superficial and can be easily palpated. Anatomical structures (tendons, bones, joints, etc) tend to hurt exactly where they are injured or inflamed.

- Flexion and Extension. Flexion and extension are movements that occur in the sagittal plane. They refer to increasing and decreasing the angle between two body parts
- Abduction and Adduction. Abduction and adduction are two terms that are used to describe movements towards or away from the midline of the body. Abduction is a movement away from the midline – just as abducting someone is to take them away.
- Medial and Lateral Rotation. Medial and lateral rotation describe movement of the limbs around their long axis: Medial rotation is a rotational movement towards the midline.
- Elevation and Depression. Elevation refers to movement in a superior direction (e.g. shoulder shrug), depression refers to movement in an inferior direction.
- Foot Bones. When thinking about foot and ankle anatomy, we usually divide the foot bones into three categories: the hindfoot, midfoot and forefoot. The Hindfoot: the hindfoot comprises of the ankle joint, found at the bottom of the leg.
- Foot Muscles. Another important part of foot anatomy is the muscles. There are more than twenty muscles in the foot and they are commonly divided into two groups
- Foot & Ankle Ligaments. Another important part of foot and ankle anatomy are the ligaments. Ligaments are strong, thick fibrous bands that connect bone to bone and hold them together.
- Foot & Ankle Tendons. Another important part of foot and ankle anatomy are the tendons. Tendons are the thick cord-like structures that attach muscles to bone.
Nov 3, 2023 · Ankle anatomy. The ankle joint, also known as the talocrural joint, allows dorsiflexion and plantar flexion of the foot. It is made up of three joints: upper ankle joint (tibiotarsal), talocalcaneonavicular, and subtalar joints. The last two together are called the lower ankle joint.

Aug 29, 2024 · Arthritis. Osteoarthritis (OA), sometimes referred to as "wear-and-tear arthritis," is the aging-related degeneration of joint cartilage that leads to joint pain, stiffness, joint deformity, and the progressive loss of mobility. In the foot, the small joints of the toes and ankles are most likely to be affected.
