Yoga Therapy

Our feet are our roots and our hands our wings... Yet on the yoga mat, this can sometimes be exactly the other way round - for instance when we use our hands to support part of our weight or even all of it.

Unfortunately, it is often only when we feel pain that we realize how much strain is put on the bones and joints in our hands and lower arms, some of which are very delicate.This is a pity because once we've understood the anatomical and functional connections, we can develop and maintain the strength of our wrists. Conversely, though, even a small but regular malposition can lead to injuries and pain in the long run.

Two wrists in each hand

The wrist has a very complex structure since it is here that seven (if we include the pisiform bone even eight) carpal bones and the two bones of the lower arm join.

This large number of bones coming together creates two joint surfaces at the wrist:

proximal joint surface

Three of the carpal bones (os scaphoideum, lunatum, triquetrum) form a ball head shaped like an egg, which rests in the socket created by the two lower arm bones (radius, ulna).

distal joint surface

The proximal (os scaphoideum, lunatum, triquetrum) and distal (os trapezium, trapezoideum, capitatum, hamatum) series of carpal bones form the middle joint line.

The two joint surfaces have different tasks:

At the proximal joint surface, a flexion towards the palm is easily possible. However, this joint quickly reaches its limits in an extension towards the back of the hand; here, the distal joint surface takes over. Since an extension of the wrist is necessary for many holding positions in which we bear weight on our hands, problems with this joint are particularly common with yoga practitioners. For this reason, precise alignment is key.

From the egg-like shape of the joint we can also derive its function. The proximal wrist is designed to move the palm towards the lower arm (flexion) and, to only a very small degree, the back of the hand towards the lower arm (extension). Lateral, waving movements (abduction and adduction) are also possible but, due to its anatomical structures, the wrist is not suited for any rotating movements.

Alignment in neutral position

In positions in which the wrist is approximately in neutral position, you should make sure that the palms are placed in parallel to the broad side of the lower arm.

In the downward-facing dog (Adho Mukha Shvanasana, for instance, your wrist is almost in neutral position or in a slight extension. Here, the entire length of the hand, both on the side of the thumb and the little finger, should be rooted into the mat with equal pressure. Lifting either of the sides would cause a rotating distortion of the wrist, a movement for which the proximal wrist is not designed.

Alignment in extension

Once the wrist has reached its maximum extension, everything seems to change. The extension movement is mainly performed by the distal wrist with hardly any changes in the position of the proximal wrist. While, in a neutral wrist position, an abduction or adduction changes the direction of the fingers in relation to the lower arm, it is now the position of the palm in relation to the lower arm that changes. Changing the direction of the fingers in relation to the lower arm now would correspond to a rotation for which the proximal wrist is anatomically not suited.

Accordingly, in positions in which the wrist is in extension, you should always make sure that your index finger is placed approximately in a right angle to your wrist. In the upward-facing dog (Urdhva Mukha Shvanasana), the handstand (Vrikshasana), the crow pose (Kakasana) and the crane pose (Bakasana), the axis of the index finger should run in approximately a 90-degree angle from the wrist since all deviations from this axis corresponded to a rotated distortion. Neither the proximal nor the distal wrist is anatomically suited for this type of movement.

Please note: this does by no means mean that your index finger has to point directly to the front in all positions in which you bear weight on your hands. In contrast, it means that it should be in a right angle in relation to the wrist. The actual direction of the index finger ultimately depends on the direction in which the wrist is positioned. Which, in turn, depends on the yoga position, the flexibility of the shoulder and the rotation ability of the lower arm.

Attentiveness and patience

Even when you pay attention to a precise alignment, all balance positions in which you support your weight with your arms represent a challenge for your wrists. For this reason, give your wrists enough time to adapt. Never practice positions with a great strain when you feel pain in them. An attentive, regular but at the same time measured practice will increase the strength in your arms and wrists. Ultimately, with correct alignment, you will experience that your hands give you as much support and stability as your feet.
