Telehealth exercise support proved workable for adolescents with chronic kidney disease

Children and adolescents living with chronic kidney disease often move less than their healthy peers, and the consequences reach beyond deconditioning. Lower activity can compound fatigue, weaken cardiovascular fitness, and make daily function harder in a population already managing repeated labs, clinic visits, and treatment burden. A pilot mixed methods study tested whether a structured telehealth program could fit into that reality for young people with CKD stages 2 through 5.

The design was intentionally pragmatic. Investigators used a 2-arm randomized waitlist control approach over 12 weeks, enrolled participants aged 11 to 18 years, and stratified randomization by CKD stage and sex. The intervention arm received video visits every 2 weeks, individualized physical activity plans, and a wearable device that tracked fitness remotely. The activity goal was straightforward: increase or maintain at least 150 minutes of moderate to vigorous physical activity each week.

Recruitment was slow, but the intervention held together

From 400 screened patients, 37 were randomized, with 19 assigned to waitlist control and 18 to the treatment group. Recruitment averaged 4 participants per month. Attrition was low at 2.7%, an important signal in a pediatric chronic disease cohort where family schedules, symptom burden, and competing medical demands frequently erode participation.

No demographic or disease-characteristic differences appeared between groups at baseline. The groups therefore began from a comparable clinical starting point, which matters in a pilot aimed at feasibility rather than efficacy. What stands out is not an efficacy endpoint or a hard clinical outcome, but whether a remote exercise structure can survive contact with real family life.

It did.

Wearables and video visits reached the bedside without replacing it

Adherence data suggested the digital components were not decorative extras. High wearable adherence was recorded in 35 participants, and median telehealth visit compliance reached 83%. For an intervention that depends on repeated contact, that level of engagement signals that remote coaching can be absorbed into routine pediatric care rather than sit outside it as a separate burden.

The clinical logic is easy to follow. Children with CKD often face reduced stamina, scheduling constraints, and uncertainty about what exercise is safe. A telehealth model lowers friction by bringing the coach to the family instead of forcing the family to navigate travel, missed school, or long gaps between in-person visits. Personalization matters here because exercise counseling in CKD is not a one-size-fits-all proposition; activity plans must account for fatigue, kidney stage, family preferences, and the day-to-day unpredictability of chronic illness.

Families described motivation, symptom interplay, and the need for personalization

Qualitative analysis of open-ended survey responses produced three categories. The first centered on accountability and motivation, with more than 30% of citations from participants and parents linking the program to instructor motivation and accountability. That finding reflects a familiar pediatric pattern: structured human contact often drives adherence more effectively than generic advice, especially when families are asked to change habits rather than simply receive information.

A second category captured the interplay between physical or mental health and physical activity. Among participant responses, physical health accounted for 44% of the citations in this theme. In chronic kidney disease, exercise behavior rarely exists in isolation; it is shaped by fatigue, mood, symptom burden, and the child’s sense of what is possible on a given day. A telehealth program can acknowledge those fluctuations instead of treating missed activity as noncompliance.

The third category centered on personalization of the program to limit barriers to implementation, accounting for 52% of participant citations. That theme is especially relevant for CKD, where treatment plans are often overlaid on school demands, family logistics, and other medical appointments. Personalized plans do more than improve convenience. They help translate a physiologic target, such as 150 minutes per week, into a schedule that fits a child’s actual life.

Why this matters for pediatric nephrology practice

Physical inactivity is not a cosmetic issue in pediatric kidney disease. Reduced movement can accelerate loss of conditioning, narrow opportunities for social participation, and make chronic illness feel even more restrictive. In that setting, a telehealth-supported model has practical appeal because it reduces geographic barriers and gives clinicians a mechanism to reinforce activity without requiring frequent in-person visits.

The study also suggests that remote monitoring may be more than a compliance tool. Wearables provide immediate feedback that can help families see progress, identify lapses, and connect behavior with symptoms or schedules. For clinicians, that creates a more concrete conversation about activity than a single retrospective question at follow-up.

At the same time, the study remains a pilot. Feasibility and acceptability are the right first questions, but they are not the final ones. No efficacy claims on kidney outcomes, fitness changes, or long-term behavior change can be drawn from these data alone. The sample was small, and the intervention was tested over 12 weeks, which is enough to judge engagement but not enough to define durability.

A workable model still needs harder outcome data

The strongest signal from this pilot is that adolescents with CKD and their caregivers can stay engaged with a telehealth exercise model when the program is individualized, monitored, and reinforced through regular contact. The recruitment rate, low attrition, wearable adherence, and visit compliance all point in the same direction.

Future work will need to determine whether those process gains translate into sustained activity, improved physical function, and better health-related quality of life. It will also need to clarify which children benefit most, which family barriers remain resistant to telehealth support, and whether the model can scale beyond a pilot setting without losing the personal coaching that made it acceptable in the first place.
