Long-Term Effects of Torso-Weighting (TWPS)

9 października 2018 zaktualizowane przez: 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.

Szczegółowy opis

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.

Eksperymentalny: 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.

Opis środka
Ramy czasowe
Sensory Organization Test
Ramy czasowe: 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
change from initiation to 2-weeks after initiation of daily wearing of TW or SW
Gait Velocity
Ramy czasowe: change from initiation to 2-weeks after initiation of daily wearing of TW or SW
As measured using instrumented gait mat.
change from initiation to 2-weeks after initiation of daily wearing of TW or SW
Movement Ability Measure, Computer Adaptive Test Version (MAM-CAT)
Ramy czasowe: change from initiation to 2-weeks after initiation of daily wearing of TW or SW
Online self-report of perceived current movement ability and preferred movement ability. The scores are reported in standardized logits, 0-6, where 6 is competitive level athletic movement. The reported values are the average change in current movement ability from initiation of daily wear to after 2 weeks of daily wear of TW or SW.

Activities-Specific Balance Confidence Scale
Ramy czasowe: change from initiation to 2-weeks after initiation of daily wearing of TW or SW
Self-report measure of perception of confidence under various balance challenges on a scale of 0-100 with 100 being fully confident that the individual can perform the listed balance challenge without falling. Data reported reflect the difference in scores from initiation to the 2-week point after initiation of TW or SW.
