Outcome Measures

Primary Outcomes (4)

  • PROMIS (Patient Reported Outcomes Measurement Information System) Physical Functioning

    Ability to carry out activities that require physical actions, ranging from self-care (activities of daily living) to more complex activities that require a combination of skills, often within a social context. Scores are standardized T-scores with mean of 50 and standard deviation of 10; higher scores indicate better physical function.

    Baseline, 1 month, 2 months and 3 months

  • Sleep Efficiency

    The ratio of time asleep over time in bed gathered from sleep diaries completed at bedtime and at awakening. Scores range from 0 to 100%, higher values indicate better sleep efficiency or more time sleeping in bed.

    Baseline, 1 month, 2 months and 3 months

  • Steps Per Day

    Count of steps per day using activity monitor worn on upper arm.

    Baseline, 1 month, 2 months and 3 months

  • PROMIS (Patient Reported Outcomes Measurement Information System) Fatigue

    Assesses fatigue from mild subjective feelings to an overwhelming, debilitating, and sustained sense of exhaustion that is likely to decrease one's ability to carry out daily activities, including the ability to work effectively and to function at one's usual level in family or social roles. Fatigue is divided conceptually into the experience of fatigue (e.g., frequency, duration, and intensity), and the impact of fatigue upon physical, mental and social activities. Scores are on a T-metric with mean of 50 and standard deviation of 10; higher scores indicate greater fatigue.

    Baseline, 1 month, 2 months and 3 months

Study Arms (1)

Glutathione supplement

EXPERIMENTAL

All subjects will be taking a glutathione supplement.Glutathione is a naturally occuring antioxidant and a nonessential amino acid.

Dietary Supplement: Glutathione

Interventions

GlutathioneDIETARY_SUPPLEMENT

glutathione is a dietary supplement and an antioxidant. Subjects will take 1000 mg per day for three month. Each capsule contains 500 mg glutathione.

Also known as: 500 Ultrathoine, GSH and l-glutathione.

Eligibility Criteria

Age50 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Ability to walk 100 feet with usual assistive devices (ex. cane or walker)
  • Having a function score of 18-32 when tested with the IPPS (Index of Post- Polio Sequelae). This will include people with post-polio symptoms in a very specific range of severity.

You may not qualify if:

  • Having another serious medical condition (cancer, multiple sclerosis, etc.)or inflammatory disease (ie., lupus)

Limitations and Caveats

Sample size of 20 was quite small to make generalizations to the larger population. Dosing and duration of the intervention may not have been sufficient to effect change.
