Objective In this study, the concept of a cognitive dual-task performance and visual restriction during walking has been used to study the recovery of gait after limb-saving surgery in ten patients.

Design All patients were recovering from some form of treatment to tumors of the lower limbs. Patients had to walk on a treadmill at their preferred speed. During the course of recovery, we measured normal walking, walking while performing an attention-demanding dual task, and walking during restricted vision, starting 5 mo postoperatively.

Results Patients are able to reach an acceptable level of gait within 15 mo, especially when the basic locomotor activity (i.e., step-cycle duration, walking speed, gait symmetry) is taken into account. Nevertheless, the results showed that during the recovery, the patients were still hindered by the dual task and visual restriction while walking because they exhibited a decrease in step-cycle duration under these conditions.

Conclusions In general, an improvement in walking speed and a decrease in asymmetry was seen. On the other hand, patients still had a basically reduced control of gait after the 15-mo recovery period. This can be attributed to a lack of gait automatism caused by an irreversible loss of somatosensory input.
