Latent profiles of kinesiophobia and associated factors in older patients after hip arthroplasty: a cross-sectional study
This cross-sectional study of 307 older patients in China identified three distinct latent profiles of kinesiophobia following hip arthroplasty and determined that factors such as surgical history, frailty, pain, and social support significantly influence profile membership, highlighting the need for targeted perioperative interventions.

For millions of older adults, a broken hip is not just a fracture; it is a threshold between independence and a life confined by fear. When the bone is repaired with a new joint, the physical work of healing begins, but a silent psychological barrier often stands in the way. This barrier is a deep, irrational fear of movement, a hesitation so strong that it convinces the body to stop before the muscles have even tired. In the medical world, this is known as kinesiophobia. It is a common obstacle for patients recovering from hip replacement surgery, a condition that can turn a routine rehabilitation program into a source of anxiety and avoidance. While doctors have long known that fear of movement exists in this group, they have struggled to understand that not all patients experience this fear in the same way. Some might worry about the pain but still move, while others might freeze completely at the thought of standing. To help these patients, medical professionals need to know not just that the fear is there, but exactly what shape it takes for each individual.
A team of researchers at Suining Central Hospital in China set out to map these different shapes of fear. They focused on older adults who had recently undergone hip replacement surgery, a procedure that restores mobility but requires the patient to trust their new joint with every step. The researchers gathered data from 307 patients, asking them detailed questions about their pain, their confidence in moving, the support they received from family, and their general health. Instead of treating everyone as a single group with an average level of fear, the team used a statistical method to look for hidden patterns within the data. They wanted to see if the patients naturally fell into distinct categories based on how they thought about and reacted to movement.
The study revealed that the fear of movement is not a single, uniform experience. Instead, the patients sorted themselves into three very different groups. The first group, making up about 32 percent of the patients, was the most resilient. These individuals held a healthy view of their situation; they understood that some discomfort was normal, and they adapted their behavior to keep moving forward. They were the "cognitively healthy-behaviorally adaptive" group. The second group, which was the largest at nearly 40 percent, showed signs of a shifting mindset. These patients were not as confident as the first group; they began to withdraw from activities as their thoughts became more uncertain. They were the "cognitively shifted-behaviorally withdrawn" group. The third group, comprising about 29 percent of the patients, faced the most severe challenge. These individuals held catastrophic thoughts about their movement, believing that any activity would cause harm, which led them to restrict their actions almost entirely. They were the "cognitively catastrophic-behaviorally restricted" group.
The researchers then looked closely at what factors pushed a patient into one of these three categories. They found that a patient's history and current condition played a major role. Those who had undergone surgery before were less likely to fall into the fearful groups, suggesting that prior experience with the hospital and recovery process can act as a buffer against new fears. Similarly, patients who could care for themselves well before the operation, who had a normal body weight, and who felt strong support from family and friends were more likely to belong to the healthy, adaptive group. On the other hand, patients who had multiple other health problems, who experienced nausea after the surgery, or who were already frail before the operation were much more likely to end up in the groups with high levels of fear and withdrawal. Pain was also a critical factor; those who reported higher pain levels were significantly more likely to be in the group that restricted their movement the most.
The findings suggest that a single approach to rehabilitation will not work for everyone. A patient who is physically strong but mentally anxious needs a different kind of help than one who is physically frail and terrified of pain. For those in the most fearful group, the study indicates that standard advice is often not enough; they require intensive, step-by-step support that addresses their deep-seated fears before they can even begin to exercise. For the middle group, who are wavering between confidence and fear, the focus should be on stabilizing their mindset through education and consistent encouragement. The study concludes that by identifying which group a patient belongs to, doctors and nurses can tailor their care to the specific needs of that individual, helping more older adults overcome the invisible barrier of fear and return to a life of movement.
