The biomechanics of walking change when a woman is pregnant. During the second trimester, there is weight gain and a change in the center of gravity as the shape and size of the stomach increases. At the same time, hormones relax ligaments, including the plantar fasciae. This increases foot length and the feet flatten and roll more. The arch is less able to absorb shock. During the final trimester, there is edema (severe swelling) in the ankles. This can be managed with regular exercise or, in some cases, with compression stockings.
It takes about 6-9 months post-partum for the ligaments, which include the plantar fascia, to tighten to pre-pregnancy levels. During this time, it is not uncommon to find significant heel and arch pain.
Other names or similar foot conditions:
- Arch flattening
- Pronation
- Edema
Symptoms:
- Swollen feet and ankles
- Pain in ankles, heel, arch, ball of the foot, toes
- Temporary arch flattening and pronation
- Longer length foot
- Changes in center of gravity and ability to balance
- Low back pain
Signs to look for:
- Swelling of ankles and feet
- Overpronation
- Varicose veins
- Ingrown toenails
Possible Causes:
- Weight gain and hormonal changes due to pregnancy
Goals:
- Prevent flattening of the arch during walking
- Provide shock absorption
- Stabilize center of gravity, posture and balance
- Protect feet against pressure between the toes, against the shoes, etc.
- Control edema (exercising)
How We Help:
Arch Supports:
- BioOrthotics exercising support with metatarsal lift
- Lower and thinner arch support with longitudinal and metatarsal support for use when shoes cannot accommodate the BioOrthotics exercising support
Shoes:
- Extra depth, double or triple depth shoe with high toe box, firm heel counter, rocker sole and connecting shank
- For Smart footwear, wear heel to toe rockers, negative heel shoes or shoes with titanium springs
- Avoid flip-flops. Only wear sandals with a back and only the Orthaheel, Alegria or Aetrex brand
- Avoid going barefoot or do so on a minimal basis only
Other:
- Spot stretching with ball and socket tool on shoes as necessary
- Compression hosiery products
Activities:
- Regular exercise program for aerobic and lower body strength
- Rotate weight bearing exercise (such as walking) with non-weight bearing exercise (such as swimming or bicycling)
