Does my child have tight muscles?

Stretching the iliotibChildren with generalised joint hypermobility often have loose joints but some tight muscles. The muscle tightness causes abnormal stresses in the joints and can lead to pain and discomfort. 

Hamstring and lower back muscle flexibility

Fascia lata tightness

fascia lata.jpgThe fascia lata is a thick sinew that runs from the pelvis over the outside of the hip, thigh and knee. It is connected to a broad flat sinew in the lower back (called the lumbar dorsal fascia) and provides an important  link between the trunk and the leg.

A child with tightness in the fascia lata tends to stand with the legs apart and the feet turned outwards, and also tends to sit with the legs wide apart.

Standing.jpgHere is a simple test for tight fascia lata sinews

Ask your child to stand with the feet a hand breadth apart and parallel to each other for twenty seconds. Is this position comfortable, or is it  “boring”.

Now let your child stand with the feet about 20 cm apart for another 20 seconds. Does this feel better?  Less boring? 

Even quite young children are quite clear about which position they prefer. 

Another test for fascia lata and lateral hamstring  tightness

Instruct your child to stand up and sit down 10 times slowly and with good control.


Sit low step hips legs move apart If your child has tightness and weakness in the leg muscles the legs will tend to move apart and the feet turn out as he/she sits down, especially after a few repetitions when the muscles start to tire. 

Muscle tightness may lead to pain in the legs 

Muscle tightness leads an imbalance in the acting on the joint and in the long term this can lead to pain and weakness.  Imbalance in the muscle forces acting on a joint is particularly harmful in joints that are hypermobile and need good muscle function to protect them from injury. 

Tightness in the lower back and hip muscles, along with leg muscle weakness, is often the cause of  leg pain after exercise (lots of running and walking). A program of exercises to stretch tight muscles and strengthen weak muscles will often improve leg pain. 

Tight muscles is often the cause of poor sitting posture and fidgeting

T sitting slumped_2.jpgTightness in the lower back and hip muscles makes sitting erect for working at a table tiring and uncomfortable. Children will adapt their sitting posture to accommodate the muscle tightness. The sit with the trunk flexed, the neck extended and the legs wide apart. 

Children who walk on their toes usually have rightness in the hip muscles (especially fascia lata) which makes it uncomfortable to walk with the feet flat and close together. Children with habitually walk on the toes will usually stand with their feet wide apart and also turned out. 

What can be done to stretch tight muscles? 

A regular program of active stretching will usually improve flexibility in the iliotibial tract and the hamstring muscle.  The stretching exercises need to be specially adapted to the needs of hypermobile children as it is important not apply stretching forces to hypermobile joints.
