Neuropathy Walks (Cross-sectional)

Completed
Conditions
HIV Infections
Interventions
Other: No intervention
Registration Number
NCT04889521
Lead Sponsor
Rutgers, The State University of New Jersey
Brief Summary

Cross-sectional study is to explore the impact of painful neuropathy in the feet on function in persons living with HIV (PLHIV).

Detailed Description

The overall goal of this study is to explore the impact of HIV-associated distal sensory polyneuropathy on physical performance, physical activity, and pain pressure threshold.

The aim is to determine if the presence of painful distal sensory polyneuropathy in the feet adversely affects physical performance, physical activity, and pain pressure threshold in PLHIV.

Primary Outcome Measures
NameTimeMethod
Gait - Step LengthWeek 0 (one-time)

Spatial characteristic of gait measured in meters as captured with a ZENO instrumented walkway

Gait - Stride WidthWeek 0 (one-time)

Spatial characteristic of gait measured in meters as captured with a ZENO instrumented walkway

Gait - Foot Fall AreaWeek 0 (one-time)

Spatial characteristic of gait measured in square meters as captured with a ZENO instrumented walkway

Gait - CadenceWeek 0 (one-time)

Temporal characteristic of gait measured in steps per minute as captured with a ZENO instrumented walkway

Physical PerformanceWeek 0 (one-time)

Physical performance score generated via the Short Physical Performance Battery. (SPPB). SPPB procedures generate a total score reflective of physical performance. Minimum score=0; maximum score=12; lower score=worse outcome

Gait - Walking velocityWeek 0 (one-time)

Temporal characteristic of gait measured in m/sec as captured with a ZENO instrumented walkway

Gait - Step TimeWeek 0 (one-time)

Temporal characteristic of gait measure in seconds as captured with a ZENO instrumented walkway

Secondary Outcome Measures
NameTimeMethod
Walking EnduranceWeek 0 (one-time)

Walking endurance as measured with the 6-Minute Walk test (distance walked over span of 6 minutes).

Whole Body StrengthWeek 0 (one-time)

Mid-thigh pull test will be used to generate a score expressed as force in pounds or kilograms that is reflective of whole body strength.

Pain pressure thresholdWeek 0 (one-time)

Pain pressure threshold (expressed in pounds or kilograms of force) at lower extremity landmarks via use of a digital algometer

Physical Activity5 days from date of all other outcomes

Physical activity characteristics: (1) over a span of 5 days captured via a wrist-band style Actigraph activity monitor; (2) self-reported physical activity over past 7 days using International Physical Activity Questionnaire - Short Form
