TENSTENSParticipants received a TENS device to treat their chronic pain and took part in a digital MSK program, which provided customized exercise therapy sessions, educational articles, and access to coaches and physical therapists. Participants were encouraged to use the TENS device for at least 1 hour daily for 4 weeks.
HFITHFITParticipants received a HFIT device to treat their chronic pain and took part in a digital MSK program, which provided customized exercise therapy sessions, educational articles, and access to coaches and physical therapists. Participants were encouraged to use the HFIT device for at least 1 hour daily for 4 weeks.

Primary Outcome Measures
NameTimeMethod
Pain MCIDBaseline and Week 4

Pain will be measured by the Numeric Pain Rating Scale, ranging from 0 (no pain) to 100 (worst possible pain). The minimal clinically important difference (MCID) of pain will be achieved (0/1) if there is at least a 34% or 23 point improvement, as based on literature.

Secondary Outcome Measures
NameTimeMethod
Function MCID (Knee)Baseline and Week 4

Knee function will be measured by the Knee Injury and Osteoarthritis Outcome Score - Physical Short Form (KOOS-PS, 0-100, higher indicates worse function). Function MCID will be achieved (0/1) if there is at least an 8 point improvement in KOOS-PS, as based on literature.

Opioid useBaseline and Week 4

Opioid use data will be collected through survey questions. The percentage of users who use opioids in each group during the study will be compared.

Function MCID (Back)Baseline and Week 4

Back function will be measured by the Roland-Morris Disability Questionnaire 11-item (RMDQ-11, 0-100, higher indicates worse function) scores for back users. Function MCID will be achieved (0/1) if there is at least a 30% improvement in RMDQ-11, as based on literature.

AnxietyBaseline and Week 4

Anxiety will be assessed by the Generalized Anxiety Disorder 2-item (GAD-2, 0-6, higher is worse) scores. A score of 3 or higher is defined as screening in for having anxiety, based on literature. The percentage of users who screen in for anxiety in each group will be compared.

DepressionBaseline and Week 4

Depression will be assessed by the Patient Health Questionnaire 2-item (PHQ-2, 0-6, higher is worse) scores. A score of 3 or higher is defined as screening in for having depression, based on literature. The percentage of users who screen in for depression in each group will be compared.
