Decreased muscular strength and poorer postural stability impact the physical function of breast cancer survivors (BCS) and increases their risk of falls. Gait assessment, particularly in the backward direction, is often used as an indicator of fall risk in several populations. However this information is unknown in BCS.What are the differences in forward, backward, and accelerated forward walking in BCS in comparison to individuals without a prior cancer diagnosis?17 postmenopausal BCS (mean age: 58.5 (8.5) years) and 17 age-matched women without a prior cancer diagnosis (mean age: 59.11 (5.55) years) completed 5 trials each of forward, backward, and fast forward walking conditions. Absolute (Means) and variability (Coefficient of variation) estimates were obtained for spatio-temporal gait parameters. Lower body, upper body and handgrip strengths were measured.For absolute estimates of gait, significant group main effects indicated that BCS had 7% shorter step length (P = 0.019) and 8% slower gait speed (P = 0.048). For variability estimates of gait, there was a significant interaction for stance time (P = 0.035). BCS had greater stance time variability during forward and fast forward conditions, but lesser variability during backward condition. Averaged across all the conditions, BCS had 38% greater step length variability (P = 0.043), 50% greater gait speed variability (P = 0.028), and 28.5% greater single support time variability (P = 0.004). Averaged across both the groups, all the variables except for swing time variability were significantly different among the conditions (all P< = 0.013). BCS also had significantly reduced upper body strength (P = 0.036).Slower and shorter steps while walking both forwards and backwards could be indicative of a more cautious gait strategy by BCS. Also, BCS possibly focused on controlling spatial parameters during forward walking but temporal parameters while backward walking. Whether these alterations are related to an increased fall risk within BCS needs to be determined.
