Detaillierte Beschreibung
The long-term goal of this research is to establish the effectiveness of a mechanism-based therapeutic intervention for improving balance and mobility functions and preventing falls in older adults with type 2 diabetic peripheral neuropathy (DPN).
Specific Aim 1 will determine if combined high intensity isolated leg muscle power exercise with balance perturbation training (ActiveStep) and aerobic exercise achieves greater improvements in balance stabilization (protective stepping behavior and kinematics) and mobility function (gait parameters and timed functional measures) than a lifestyle based intervention that primarily focuses on aerobic exercise through underlying mechanisms of improved neuromuscular activation (rate and magnitude) and sensorimotor control, improved muscle quality, and increased blood flow to enhance neuromuscular and sensorimotor performance in people with DPN.
Specific Aim #2: To determine if a neuromotor balance training program combined with muscle power exercise training and aerobic exercise, leading to improved neuromuscular and sensorimotor mechanisms, is more effective in improving clinical tests of balance and mobility functions in those with DPN compared with a traditional exercise intervention.

Beschreibung
Inclusion Criteria:
- HbA1C of 5.7% to 9.0% or a fasting blood glucose of greater than or equal to 100
- Participants that are diabetic should be stable on medications for at least 3 months prior to entering the study
- Neuropathy is most likely caused by impaired glucose regulation determined by medical or family history
- Autonomic neuropathy as defined by Toronto Neuropathy Expert Group 2010/2011 consensus criteria
- Medically stable at time of enrollment as determined by screening process
Exclusion Criteria:
- Neuropathy due to factors other than impaired glucose regulation determined by screening process
- Other severe medical illness or condition that would preclude safe participation in the study as determined by the study team
- Severe Autonomic Neuropathy that would limit study participation
- Musculoskeletal limitations that would preclude participation in balance assessment of protective stepping

Maßnahmenbeschreibung |
Zeitfenster |
---|---|---|
Change in clinical balance as measured by the Four Square Step Test
Zeitfenster: baseline, 3 months, and 6 months
|
The Four Square Step Test (FSST) will be used to evaluate changes in clinical balance.
The FSST is a single item, evaluator-administered tool that assesses the ability to change directions while stepping.
It requires the individuals to move in the anterior-posterior and medial-lateral directions while stepping.
Changes from baseline to 3 and 6 months will be examined.

|
Change in mobility as measured by the modified physical performance test
Zeitfenster: baseline, 3 months, and 6 months
|
The modified physical performance test will be used to evaluate changes in mobility.
This test requires individuals to perform a variety of every day tests such as going up and down the stairs, standing from a chair, and putting on a coat.
Changes from baseline to 3 and 6 months will be examined.
