Effects of two exercise training techniques on walking function in adult patients with stroke.
BACKGROUND
Patients with stroke usually demonstrate activity limitations manifested by reduced ability to perform daily functions.


OBJECTIVE
The purpose of this study was to examine the effects of treadmill walking and overground walking exercise training on walking function in adult patients with stroke.


METHODS
Participants were forty (40) patients with stroke comprising 22 males and 18 females. Inclusion criteria included absence of any co-morbidity that could affect rehabilitation. They were randomly assigned to 2 exercise training groups (20 in each group). All study subjects received conventional physiotherapy rehabilitation for 12 weeks. During the same period, subjects in Group A had treadmill walking exercise training (TWET) while those in Group B had overground walking exercise training (OWET) in addition to the conventional physiotherapy. Outcomes were measured as (i) Ten-metre walk time and (ii) Six-minute walk distance. They were evaluated at entry into the study and at the end of every 4 weeks. Results at weeks 0, 4, 8 and 12 were used for analysis. For each of the 2 groups, paired t-tests were used to evaluate the significance of the differences between the pre-intervention (week 0) mean scores on both tests and the mean scores at weeks 4, 8 and 12.


RESULTS
With 12 weeks of exercise training, both TWET and OWET produced significant improvement in walking function (P < 0.05). However, OWET resulted in significantly greater reduction (26.8%) in mean walking time over 10 metres than TWET (22.6%); and significantly greater increase (45.2%) in mean walking distance over 6 minutes than TWET (31.0%).


CONCLUSIONS
Exercise training, especially overground walking, could be integrated into the traditional rehabilitation care given to adult patients with stroke.
