December 19, 2021 updated by: Taipei Veterans General Hospital, Taiwan

The Effect of Home Based Walking Exercise on Fatigue, Anxiety, Depression, Sleep Quality, Circadian Rhythms and Quality of Life in Patients With Gastric Cancer Undergoing Gastrectomy

This study will investigate the effectiveness of a rehabilitation program in improving fatigue, negative emotions , sleep quality, circadian rhythms and quality of life in patients with gastric cancer undergoing gastrectomy in Taiwan.

  2. The negative emotions in exercise group is significant improving than usual-care group at 1st, 2nd, 3rd, 6th, 12th, 24th and 36th month.
  3. The sleep quality in exercise group is significant improving than usual-care group at 1st, 2nd, 3rd, 6th, 12th, 24th and 36th month.
  4. The quality of life in exercise group is significant improving than usual-care group at 1st, 2nd,3rd, 6th, 12th, 24th and 36th month.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: exercise group
A 12-week regimen of home-based walking exercises, comprising walking at a moderate intensity for 40 min, three times a Week.
Behavioral: exercise group

exercise education: A 12-week regimen of homebased walking exercises, include moderate intensity for 40 min, three times a week.

We explained the participants how to perform the exercises, according to an instruction manual for the exercise regimen. Participants were instructed that the exercises would be effective only if they reached 40%-60% of the heart rate reserve, as determined by the Karvonen method, or 13-14 on the RPE.

Exercise education:

Weekly telephone or mobile application "LINE" consultations concerning exercise.we discussed whether participants' exercise fulfilled the prescribed intensity, duration, frequency and whether the participants experienced any adverse effects.
No Intervention: usual-care group
These participants follows the standard post-surgery follow-up consisting of counseling by dietitians, nurses and doctors.

sleep quality(Pittsburgh Sleep Quality Index and using Actigraph)
Time Frame: baseline (one week after recruited)
The Pittsburgh Sleep Quality Index (PSQI) contains 19 self-rated questions and 5 questions rated by the bed partner or roommate (if one is available). Each item is weighted on a 0-3 interval scale. The global PSQI score is then calculated by totaling the seven component scores, providing an overall score ranging from 0 to 21, where lower scores denote a healthier sleep quality. Actigraph is the gold standard for evaluating sleep disorders. As the name suggests, it is an electrophysiological recording of multiple parameters, including total sleep time(TST), sleep efficiency(SE), and sleep onset latency(SOL) which help to score various sleep stages.
