Effects of walking poles on lower extremity gait mechanics.
There were differences in kinetic variables between walking with and without poles. The use of walking poles enabled subjects to walk at a faster speed with reduced vertical ground reaction forces, vertical knee joint reaction forces, and reduction in the knee extensor angular impulse and support moment, depending on the poling condition used. Willson et al., 2001
Changes in in vivo knee contact forces through gait modification
The results of this study suggest that an optimal configuration of bilateral hiking poles may significantly reduce both medial and lateral compartment knee forces in individuals with medial knee osteoarthritis. Kinney et al., 2013
Health benefits of Nordic walking: a systematic review.
A study by Henkel et al. (2008) found effect of selected prevention concepts on functional health of persons with nonspecific chronic recurrent neck pain. Observed a reduced in unspecific, chronic neck pain and increased quality of life Tschentscher et al., 2013
Supervised and non-supervised Nordic walking in the treatment of chronic low back pain a single blind randomized clinical trial.
For pain, disability, and patient specific function the supervised Nordic walking group generally faired best however no statistically significant differences were found. Hartvigisen et al., 2010
Does moderate-to-high intensity Nordic walking improve functional capacity and pain in fibromyalgia? A prospective randomized controlled trial.
Moderate-to-high intensity aerobic exercise by means of Nordic walking twice a week for 15 weeks was found to be a feasible mode of exercise, resulting in improved functional capacity and a decreased level of activity limitations. Pain severity did not change over time during the exercise period. Mannerkorpi et al., 2010
Effects of Nordic Walking and Pilates exercise programs on blood glucose and lipid profile in overweight and obese postmenopausal women in an experimental, nonrandomized, open-label, prospective controlled trial.
Exercise training in accordance with the NW model causes statistically and clinically more significant changes in glucose and basic blood lipid levels than do Pilates and dietary intervention alone. Hagner-Derengowska et al., 2015
