4.9 Partial weight bearing (PWB)

The user slides the upper limbs on the horizontal bars forward to an arm's length distance. Then the user puts weight on the parallel bar using the upper limbs and moves the affected/involved lower limb forward (bearing less than 50% of body weight on the affected/involved lower limb). And the other 50% body weight is shared between unaffected lower limb and the horizontal bars. The user finally moves forward to complete the cycle. The user is made to repeat this cycle in order to continue to move forward.
