Long-Term Effects of Torso-Weighting (TWPS)
2018年10月9日 更新者：San Francisco State University
Long-Term Effects of Balance-Based Torso-Weighting: Pilot Study
The goal of this pilot study is to test the protocol for investigating the longer-term effects of torso weighting on physical activity, number of falls, and muscle activation (when muscles turn on and off and how intensely) in five volunteers with multiple sclerosis.
The hypotheses of this study include: torso weighting will (1) increase physical activity, (2) decrease the number of falls, and (3) improve the timing and coordination of muscle activation during balance perturbations.
調査の概要
詳細な説明
Torso weighting, using the balance-based torso-weighting (BBTW) method, is an intervention that addresses balance by first challenging stability in standing using a series of perturbations (nudges) and resisted rotations to people.
Challenging stability allows the assessor to determine directional instability.
Once the direction of instability is determined, small weights are placed on a vest-like garment and retesting of balance occurs.
In this study, participants will be tested with no weights (NW), with sham weights (SW), and with BBTW weighting (WT).
Following non-weighted baseline assessment, participants will be randomly allocated into the sham weight condition or BBTW weight condition in a cross-over design.
The initial condition (NW) will last four weeks and the final two conditions (SW,WT) will last two weeks each.
Following each condition, outcome measures will be reassessed.
Throughout the study, participants will be asked to wear a commercially-available remote monitoring device (e.g., Fitbit Flex) and keep a daily log of physical activity and number of falls.
During the SW and WT conditions, participants will wear the assigned garment for 2-4 hours daily.

実験的：Torso Weights then Sham Weights
No weights worn for 4 weeks. Garment with torso weights worn 2-4 hours daily for 2 weeks. Then participants cross-over to wear garment with sham weights for 2-4 hours daily for 2 weeks. Participants wear the Fitbit Flex throughout. |
Following assessment of an individual's directional instability, small weights are applied to a vest-like garment to correct balance loss.

Sensory Organization Test
時間枠：change from initiation to 2-weeks after initiation of daily wearing of TW or SW
|
balance tested during 6 conditions on Neuro-com forceplate and surround and reported as a composite score (across the six conditions), 0-100, with higher scores indicating better balance; measure reported reflects change in the composite score from the visit that initiates Torso-weighting (TW) or sham weights (SW) to the visit that concludes daily wearing of TW or SW
