Individualized Prehabilitation for Enhancing Recovery and Surgical Outcomes in Patients Undergoing Radiotherapy and Surgery for Soft Tissue Sarcoma

Univariate descriptive statistics and frequency distributions will be calculated, as appropriate for all variables. Baseline values for demographic, clinical, and outcome variables will be tabulated for the treatment groups.

Univariate descriptive statistics and frequency distributions will be calculated, as appropriate for all variables. Baseline values for demographic, clinical, and outcome variables will be tabulated for the treatment groups. Between-group effect sizes will be estimated for continuous outcomes.

This is a self-report measure comprising 30 items (23 for activities of daily living; 7 items for role participation). Will use this measure, completed using observed performance for feasible items and self-report for the remaining items (getting in and out of a car, shopping; driving). Univariate descriptive statistics and frequency distributions will be calculated, as appropriate for all variables. Baseline values for demographic, clinical, and outcome variables will be tabulated for the treatment groups. Between-group effect sizes will be estimated from a mixed model which considers the individual as a cluster with multiple measures per person.

Functional walking capacity is defined as walking capacity needed for everyday activities of daily living such as shopping, traveling to and from work, and walking in the workplace or public buildings. The six minute walk test (6MWT) is the gold standard measure for this. The units are distance in meters covered during the test. There is a standardized mobile application for measuring and data comes minute by minute to assess fatigability. Univariate descriptive statistics and frequency distributions will be calculated, as appropriate for all variables.

Gait quality will be measured during the 6MWT using a wearable developed by the team, Heel2Toe sensor. The parameters of gait quality will include proportion of steps with as strong a heel strike pre-operatively, as well as distribution of cadence and of angular velocity. Irregular stepping pattern is indicated by lack of heel strike, large variability in cadence, stride length, and angular velocity as indicated by coefficient of variation. Univariate descriptive statistics and frequency distributions will be calculated, as appropriate for all variables.

Daily step count for the duration of the study will be obtained using the native accelerometer/gyroscope and pedometers available on both iPhone and android devices. Will summarize this complex data using benchmarks of 1, 3, 5, 7, 9 (000 steps) based on meaningful physical activity targets. Will measure the time to achieve these targets post-surgery. These will be captured for the 9 week prehabilitation period and the post-surgery recovery period. As indicated, will focus on steps taken outside of the house as "in house" steps tend to be of very low cadence. For step counts, time to reach the benchmarks of 1, 3, 5, 7, 9 (000 steps) will be calculated and presented descriptively. Univariate descriptive statistics and frequency distributions will be calculated, as appropriate for all variables.

Symptom status will be assessed using the Edmonton Symptom Assessment Scale which assesses 7 symptoms including pain, fatigue, distress, and overall well-being. Univariate descriptive statistics and frequency distributions will be calculated, as appropriate for all variables.

Global health related quality of life will be measured using the 5-level EQ-5D version (Euroqol Group) and the Patient Generated Index will be used to assess quality of life. Univariate descriptive statistics and frequency distributions will be calculated, as appropriate for all variables.
