Randomized clinical trial comparing Nordic pole walking and a standard home exercise programme in patients with intermittent claudication.
BACKGROUND
This was a randomized clinical trial to determine whether Nordic pole walking (NPW) is more effective in improving walking distance than a standard home exercise programme (HEP) in patients with intermittent claudication.


METHODS
Fifty-two patients with stable claudication were allocated randomly to a standard HEP or NPW group, and asked to complete three 30-min walks per week for 12 weeks. Claudication distance (CD) and maximum walking distance (MWD) were measured at 0 (baseline), 4, 8 and 12 weeks. Patients in the NPW group were tested with (NPW+) and without (NPW-) poles.


RESULTS
For NPW+, CD increased immediately from a median (range) of 124 (71-248) m to 148 (116-426) m, and MWD from 248 (149-900) to 389 (194-1099) m (P = 0.004 and P < 0.001 respectively). By 12 weeks, CD had further increased to 199 (118-550) m and MWD had more than doubled to 538 (250-1750) m (P < 0.001 and P = 0.001). For NPW-, CD at 12 weeks had increased significantly to 151 (100-328) m and MWD to 400 (200-900) m (P < 0.001 and P = 0.006 respectively). At 12 weeks the changes in the standard HEP group were not significant, despite excellent compliance: CD from 107 (56-332) to 153 (59-321) m and MWD from 355 (92-600) to 334 (149-874) m (P = 0.030 and P = 0.260 respectively).


CONCLUSIONS
A 12-week exercise programme using Nordic poles significantly improved walking distance in claudicants compared with a standard HEP.
