Identifying Factors Contributing to Kinesiophobia in Kidney Transplant Patients Based on the Fear-Avoidance Model: A Qualitative Study

Chronic kidney disease (CKD) continues to pose a significant global health challenge, with the number of new cases escalating dramatically over the past three decades. In China, this burden is particularly pronounced, affecting millions and underscoring the critical need for effective management strategies. For individuals progressing to end-stage kidney disease (ESKD), kidney transplantation offers a lifeline, yet the journey post-transplant is fraught with unique challenges, notably the emergence of kinesiophobia, or the irrational fear of physical movement. This fear can significantly impede recovery and the long-term health of the transplanted organ, prompting a recent qualitative study in Northeast China to delve into the multifaceted factors contributing to this condition.

The study, published in Frontiers in Psychology, employed a descriptive phenomenological approach to explore the experiences of 13 kidney transplant patients exhibiting kinesiophobia. These patients, all within six months of their surgery and scoring above 17 on the Tampa Scale for Kinesiophobia (TSK-11), underwent in-depth semi-structured interviews. The findings reveal a complex interplay of physiological, psychological, support system, and environmental factors that collectively fuel this debilitating fear, ultimately impacting the vital process of organ recovery.

Understanding the Growing Burden of Kidney Disease

Globally, CKD prevalence has surged, with figures rising from 7.8 million in 1990 to 18.99 million in 2019. China bears a substantial portion of this burden, with an estimated 159.8 million individuals suffering from the condition. By 2018-2019, approximately 25% of Chinese adults had stage 3 CKD, and 1.8% had more advanced stages (4-5). As CKD advances to ESKD, kidney transplantation emerges as a primary treatment option, surpassing dialysis in many cases. However, the success of transplantation hinges not only on the surgical procedure but also on the patient’s post-operative management and adherence to healthy lifestyle practices, including regular physical activity.

The Emergence of Kinesiophobia Post-Transplantation

Despite the life-saving nature of kidney transplantation, recipients often face a cascade of post-operative challenges. These can include diminished muscle mass, persistent fatigue, substantial financial strain, and an increased risk of cardiovascular events. Consequently, many patients develop a profound apprehension towards exercise, fearing it might overexert or damage the newly transplanted kidney. This condition, known as kinesiophobia, can lead to a detrimental cycle of reduced physical activity and poorer health outcomes. Previous research has indicated a high prevalence of kinesiophobia among kidney transplant patients in China, with rates reaching 62.6%. Factors such as age, education level, time elapsed since surgery, fatigue, depression, and self-efficacy in managing chronic conditions have been identified as significant influences.

Current guidelines, such as those from the British Kidney Society, strongly advocate for regular exercise post-transplantation, recommending at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity activity per week to mitigate risks of mortality, obesity, osteoporosis, and cardiovascular disease. However, adherence to these recommendations remains alarmingly low, with a longitudinal study revealing that only 25% of kidney transplant patients meet these activity levels, falling behind patients with other chronic illnesses. This gap in physical activity not only compromises the transplanted organ’s function but also increases the risk of cardiovascular complications, a leading cause of mortality in this population. Failure to maintain transplanted kidney function necessitates a return to dialysis, imposing immense strain on healthcare systems, organ allocation resources, and patient finances.

Framing the Fear: The Fear-Avoidance Model

To gain a deeper understanding of kinesiophobia in this specific patient group, the current study adopted the fear-avoidance model as its theoretical framework. This model, initially proposed to explain how painful experiences can lead to a cycle of fear and avoidance of physical activity, has been extended to various patient populations, including those with cardiovascular diseases and fractures. The model posits that psychological, environmental, experiential, and susceptibility factors interact to foster kinesiophobia, which in turn can negatively impact recovery and increase the risk of complications. Given the critical six-month period post-transplantation in China, a time when infection risk is high and patients are advised to limit social interactions, this study focused on patients within this timeframe, aiming to provide crucial insights into the underpinnings of their exercise fears.

Research Methodology and Participant Profile

The study employed a descriptive phenomenological qualitative research method, adhering to the Standards for Reporting Qualitative Research (SRQR). Participants were recruited from a tertiary hospital in Northeast China between June and September 2025, using purposive sampling with maximum variance to ensure diversity in age, gender, marital status, and educational background. A total of 13 patients, aged 20 to 58 (average 38.54), with a mean of 3.5 months post-transplantation, were interviewed. The sample included 5 female patients, 7 of whom had undergone pre-operative dialysis, and only 2 had returned to work. The TSK-11 scale was used to confirm kinesiophobia, with a score above 17 indicating its presence. The scale, culturally adapted for Chinese kidney transplant patients, demonstrated good reliability (Cronbach’s alpha = 0.856).

Ethical considerations were paramount, with the study receiving approval from the First Affiliated Hospital of China Medical University and adhering to the Declaration of Helsinki and Istanbul Declaration. All participants provided written informed consent after being fully informed about the study’s purpose, procedures, potential risks, and benefits. Privacy was maintained by anonymizing participant data. Rigor in the qualitative research was ensured through a unified interview outline, reflective journaling, and participant feedback to confirm findings.

Data collection involved semi-structured interviews lasting approximately 39-48 minutes, conducted by a single researcher with extensive clinical experience. The interviews were audio-recorded and supplemented with notes on non-verbal cues. Data analysis utilized the Colaizzi seven-step method, involving multiple readings, identification of significant statements, formulation of concepts, theme and sub-theme classification, integration of results, comprehensive description, and validation of findings with participants.

Unveiling the Four Pillars of Kinesiophobia

The qualitative analysis identified four overarching themes and eleven sub-themes that contribute to kinesiophobia in kidney transplant patients:

1. Physiological Factors: The Body’s Post-Transplant Reality

• Reduced Body Function: The protracted medical journey, from pre-operative dialysis to post-transplant recovery, leaves many patients with diminished physical capacity. Fatigue, weakness, and lack of stamina are common, leading to a natural inclination to limit activity. One participant expressed, "Before the dialysis, my health was already quite poor. Now that the surgery is over, I always feel weak and exhausted even when doing household chores. I always want to lie down." This physical limitation directly fuels the perception that exercise is too strenuous and potentially harmful.

• Increased Sensitivity to Postoperative Discomfort: Patients often become hyper-aware of their bodies post-transplant, particularly concerning surgical incision sites and any new physical sensations. The fear that mild discomfort, such as muscle soreness or a rapid heartbeat, might be related to damage to the transplanted kidney or surgical complications leads to a strong avoidance of physical activity. As one patient shared, "After I exercised too much, I felt some pain at the incision site in my kidney area, my muscles were sore, and I also felt short of breath. I was worried that the exercise might damage the transplanted kidney." This heightened sensitivity can misinterpret normal post-operative sensations as grave threats.

2. Psychological Factors: The Mind’s Protective, Yet Hindering, Mechanisms

• Excessive Vigilance Towards Transplanted Kidneys: Patients develop an intense emotional attachment and concern for their new organ. This vigilance manifests as a constant worry that any physical exertion could dislodge, injure, or infect the transplanted kidney, leading to a potential return to dialysis. Statements like, "Every time I do a little bit of movement, I always feel uncomfortable in the new kidney area, with a pulling sensation. I’m very afraid that the incision will split open, so I do not dare to exercise," highlight this pervasive anxiety.

• Decreased Exercise Self-Efficacy: The psychological toll of transplantation, including anxiety about future health and potential rejection, erodes patients’ confidence in their ability to engage in physical activity. This diminished self-efficacy leads to a belief that they are incapable of exercising safely or effectively, reinforcing avoidance behaviors. One participant lamented, "My current physical condition is that of a complete wreck. Just being able to stay alive is a blessing. What else can I do? I just prefer to lie down!"

• Low Self-Esteem and Feelings of Stigma: The long-term need for immunosuppressants often necessitates social isolation in the initial post-operative period to prevent infections. This isolation can lead to feelings of worthlessness and a sense of being different or stigmatized. Past roles and social connections may be lost, impacting self-perception and further discouraging participation in activities that might draw attention or highlight their altered circumstances. "Previously, I was a cycling coach. The doctor said that I was prone to infection 6 months after the kidney transplant and told me not to engage in excessive social activities. I could not return to my previous job either. I truly felt that I was useless," revealed one participant.

3. Support System Factors: Gaps in Guidance and Companionship

• Insufficient Guidance from Medical Staff: While medical professionals focus on medication and diet, comprehensive education on post-operative exercise remains a critical unmet need. Patients often lack clear, tailored advice on appropriate exercise types, frequency, and precautions, leading them to rely on general advice or traditional beliefs that prioritize rest. "The doctor only told me to do some appropriate exercise, but he did not specify the exact type of exercise. I just did exercise by walking," illustrates this deficiency.

• Lack of Companionship from Family or Friends: The vulnerability of the post-transplant period, coupled with fear of infection, can lead patients to reduce social interactions. This isolation, combined with a lack of accompanying family or friends during potential exercise, amplifies fears of engaging in physical activity alone, further reinforcing sedentary behavior. "My family does not have time to accompany me, and I’m also afraid of getting into an accident by going for exercise alone, so I do not dare to do exercise," expressed a participant.

• Scarcity of Exercise Rehabilitation Resources: A significant gap exists in accessible, specialized exercise rehabilitation programs for kidney transplant patients. The absence of dedicated centers or readily available professional guidance makes it challenging for patients to find safe and effective ways to re-engage with physical activity, leaving many feeling lost and hesitant. "After I’m discharged from the hospital, I have to undergo regular follow-up visits. I do not know where I can get involved in the rehabilitation activities related to kidney transplantation, so I can only stay at home," stated one interviewee.

4. Environmental Factors: Navigating External Influences

• Unfavorable Weather Conditions: In regions with harsh climates, such as Northeast China, adverse weather can further deter kidney transplant patients from outdoor activities. The perceived risk of catching a cold or exacerbating health issues due to environmental conditions reinforces indoor confinement and a general reluctance to engage in physical exertion. "It’s too cold in winter. I do not even want to go out to buy groceries, let alone do any exercise," shared a participant.

Implications for Clinical Practice and Future Research

The findings of this study underscore the urgent need for a more holistic and patient-centered approach to post-kidney transplantation care. The identified factors highlight several critical areas for intervention:

• Early Symptom Management and Education: Healthcare providers must prioritize the early identification and effective management of physiological symptoms like fatigue and postoperative discomfort. Simultaneously, comprehensive patient education on the benefits and safe implementation of exercise is crucial. Utilizing interventions like mindfulness-based relaxation techniques or Enhanced Recovery After Surgery (ERAS) protocols can pave the way for improved physical recovery and reduced fear.

• Enhancing Psychological Well-being and Self-Efficacy: Addressing psychological factors such as excessive vigilance, low self-efficacy, and feelings of stigma is paramount. Medical staff should work to establish a correct understanding of the disease, foster confidence in exercise capabilities, and provide support to mitigate negative emotions and improve self-esteem. Psychological interventions, possibly leveraging technology like virtual reality, could prove beneficial.

• Strengthening Support Systems and Resources: The study highlights a critical need for enhanced guidance from medical staff regarding exercise, robust family and friend support networks, and accessible rehabilitation resources. Establishing dedicated exercise rehabilitation centers and integrating family caregivers into the patient’s exercise plan can significantly bolster adherence and confidence.

• Adapting to Environmental Constraints: For patients living in challenging climates, providing indoor exercise options, such as guided online programs, instructional videos, or gentle practices like Tai Chi and Qigong, can help overcome environmental barriers and reduce exercise-related anxiety.

Addressing the Limitations and Charting a Path Forward

While this qualitative study offers invaluable insights, it is not without its limitations. The research was conducted in a single tertiary hospital in Northeast China, which may limit the generalizability of the findings to other cultural contexts or healthcare settings. The focus on adults also excludes pediatric populations. Furthermore, reliance on self-reported data introduces the potential for subjective bias. Future research should consider longitudinal qualitative studies to capture the dynamic nature of kinesiophobia over time and across different patient demographics and geographical locations.

In conclusion, kinesiophobia in kidney transplant patients is a complex phenomenon influenced by a confluence of physiological, psychological, social, and environmental factors. By understanding these intricate relationships through the lens of the fear-avoidance model, healthcare professionals can develop targeted interventions. These interventions, encompassing enhanced education, psychological support, improved resource availability, and tailored exercise guidance, are vital to empowering patients, promoting adherence to exercise recommendations, and ultimately safeguarding the long-term health and function of their transplanted kidneys. The ultimate goal is to facilitate a seamless transition from fear to confidence, enabling kidney transplant recipients to reclaim their physical well-being and improve their overall quality of life.
