Study Purpose
To investigate the effects of qigong exercises on upper extremity lymphedema, arterial resistance, and blood flow velocity in breast cancer survivors
Intervention Characteristics/Basic Study Process
Experimental group performed approximately six minutes of the 18 forms tai chi qigong exercises, and the control group rested.
Sample Characteristics
-
N = 23
-
MEAN AGE = 58 years (intervention), 54 years (control)
-
MALES: 0%, FEMALES: 100%
-
KEY DISEASE CHARACTERISTICS: Females older than age 18, treated with mastectomy, lymphedema of greater than 2 cm circumferential measurement in affected versus unaffected extremity, no known neurological deficits
-
OTHER KEY SAMPLE CHARACTERISTICS: Exclusions included current adjuvant treatment, recurrence of disease, lumpectomy, pregnancy, or performing other regular exercise.
Setting
-
SITE: Single site
-
SETTING TYPE: Outpatient
-
LOCATION: Hong Kong
Phase of Care and Clinical Applications
-
PHASE OF CARE: Late effects and survivorship
-
APPLICATIONS: Elder care
Study Design
-
Pilot, single-blind, nonrandomized, controlled trial
Measurement Instruments/Methods
-
Circumferential limb volume
-
Tape measurement
-
Doppler for arterial resistance
-
Resistance Index
Results
There was an immediate circumferential decrease and blood flow resistance decrease, with increase in blood flow velocity in the experimental group. However, no girth changes between groups may indicate only temporary effects.
Conclusions
More rigorous randomized, controlled studies are needed to confirm the effects of this exercise.
Limitations
-
Small sample (< 30)
-
Risk of bias (no random assignment)
-
Findings not generalizable
Nursing Implications
Nurses should encourage limb movement and range of motion exercises for breast cancer survivors.
