Brief summary
The aim of this study was to evaluate and compare the effects of a Nordic and free walking training program on clinical, functional and biomechanical parameters of gait, in people with PD. Outcomes: Motor symptoms: Staging and severity of PD, balance, walking functional mobility, self-selected walking velocity, and rehabilitation index. Non-Motor symptoms: Cognitive function, depressive symptoms, and quality of life (QL). Outcomes Biomechanics: Kinematic parameters (spatiotemporal and dynamic stability of walking) and neuromuscular parameters (amplitude of the electromyography signal, initial and final activation threshold, activation time and co-contraction index, of the following muscles: Vastus Lateralis (VL), Biceps Femoris (BF), Tibialis Anterior (TA), Gastrocnemius Medialis (GM).
Detailed description
Introduction: Changes in clinical, functional and biomechanical parameters of gait are remarkable features in Parkinson's disease (PD). Such changes are disabling for the performance of daily living activities (DLAs) as they represent a high risk of falls and impair quality of life (QL) in this population. Although exercise is recommended as an effective model of therapeutic intervention, to minimize the symptoms of this disease, little is known about the effects of Nordic walking on motor and non-motor symptoms in patients with PD. Purpose: The aim of this study was to evaluate and compare the effects of a Nordic and free walking training program on clinical, functional and biomechanical parameters of gait, in people with PD. Experimental Design: Randomized controlled clinical trial (RCT). Study Site: Physical Education School of the Federal University of Rio Grande do Sul and the Clinical Hospital of Porto Alegre, in Porto Alegre, Rio Grande do Sul, Brazil. Methods: The sample comprised 33 participants, aged above 50 years, of both sexes, with a clinical diagnosis of idiopathic PD, with the staging of 1-4 in the Hoehn and Yahr scale (H&Y). The participants received two types of intervention: Nordic walking training program (NW, n = 16) and free walking training program (FW, n = 17), during six weeks. Aiming to evaluate the effects of the training program, the participants underwent the tests in the following period: pre-training + pre-familiarization (T1); post-familiarization + pre-training (T2); post-training (T3).
Interventions
OTHERNordic Walking
Nordic walking Training the total period of training was composed by 9-week of walking with poles, two sessions per week. The cycles were divided into four microcycles composed of three training sessions. Each training session took 60 min. Free walking aerobics training was used during the training period. These exercises were performed alternating volume and intensity. The training session was divided into three stages: (a) stretching, joint mobility, and heating; (b) main part (FW); (c) return to the calm and ultimate stretching.
OTHERFree Walking
Free walking Training The total period of training was composed by 9-week of walking without poles, two sessions per week. The cycles were divided into four microcycles composed of three training sessions. Each training session took 60 min. Free walking aerobics training was used during the training period. These exercises were performed alternating volume and intensity. The training session was divided into three stages: (a) stretching, joint mobility, and heating; (b) main part (FW); (c) return to the calm and ultimate stretching.

Experimental: Nordic walking Experimental: Nordic walking Training The total period of training was composed by 9-week of walking with poles, two sessions per week. The cycles were divided into four microcycles composed of three training sessions. Each training session took 60 min. Nordic walking aerobics training was used during the training period. These exercises were performed alternating volume and intensity. The training session was divided into three stages: (a) stretching, joint mobility, and heating; (b) main part (FW or NW); (c) return to the calm and ultimate stretching. The participants were trained with individualized prescription according to their maximum distance. A heart rate monitor, Model FT4 attached to the chest of the xiphoid process, was used to control the progression of intensity for the training cycles ranging from 60% to 80% of heart rate reserve. Additionally, we used the Borg RPE for training intensity control, which ranged between 13 and 17 of that scale.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Test Timed Up and Go | Change from baseline at 9 weeks | This teste evaluate the mobility functional in three meters of self-selected speed (TUGSS) or at forced speed (TUGFS) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Self-selected walking speed - SSWS | Change from baseline at 9 weeks | This outcome will be measure in test of walking treadmill |
| Optimal Walking Speed (OPT) | Change from baseline at 9 weeks | This outcome will be measure through of the registered image movement analysis using the three-dimensional motion analysis system (VICON) of the walking test on treadmill. |
| Quality of life (QoL) | Change from baseline at 9 weeks | The quality of life will be estimated using the World Health Organization Quality of Life. (WHOQOL-short domains: physical, psychological, social relationships, environment, and general quality of life) and (WHOQOL-Long domains: sensory abilities, autonomy, Past. Present and Future Activities, social participation, death and dying, intimacy, and general quality of life). |
| Cognitive function | Change from baseline at 9 weeks | This outcome will be measure for Montreal Cognitive Assessment (MoCA). |
| Depressive symptoms | Change from baseline at 9 weeks | This outcome will be measure for the Geriatric Depression Scale - 15 item. The scale consists of 15 dichotomous questions in which participants are asked to answer yes or no in reference to how they felt over the past week (for instance, Do you feel that your life is empty?, Do you feel that your situation is hopeless?). Scores range from 0 to 15 with higher scores indicating more depressive symptoms. |
| Locomotor Rehabilitation Index | Change from baseline at 9 weeks | The Locomotor Rehabilitation Index is a method of determining how close is the SSW compared to the Optimum Speed (Vopt). |
