Walkers are a common mobility aid for people with long-term conditions that affect their ability to walk safely. They are also used during recovery from injuries or surgeries. While walkers can provide much-needed stability and balance, there are concerns about their long-term use leading to muscle atrophy, especially in the lower limbs. Muscle atrophy refers to the wasting or thinning of muscle mass, which can be caused by disuse of muscles or neurogenic conditions. Studies have shown that using four-wheeled walkers significantly reduces lower-limb muscle activity, which could potentially lead to muscle atrophy over time. However, the influence of walker usage on muscle atrophy is not yet fully understood, and proper use, along with rehabilitation training and exercise, can help mitigate any potential negative effects.

What You'll Learn
Walker use reduces muscle activity
Several studies have investigated the impact of walker use on muscle activity, particularly in the lower limbs. One study found that walking with a four-wheeled walker (rollator) significantly reduced electromyographic (EMG) activity in lower-limb muscle groups in healthy subjects. This reduction in muscle activity can be attributed to the external support provided by the walker, allowing users to compensate for weak lower extremity muscles. As a result, the total body weight is distributed between the upper and lower extremities, reducing the muscle activity in the legs.
Ishikura (2001) also examined muscle activity during walker gait and found that muscle activity in the rectus femoris and biceps femoris was reduced, with the reduction being more pronounced at higher degrees of hip flexion. While there are conflicting findings in the literature, with Alkjaer et al. (2006) suggesting increased muscle activity in hip extensors, the potential for reduced muscle activity during walker use is a concern. This is especially true for long-term walker users, as decreased muscle activity over an extended period can lead to muscle atrophy.
Long-term reliance on walkers can lead to a decrease in the frequency of use of lower limb and core muscles, resulting in muscle atrophy. This atrophy occurs due to disuse of the muscles, as the body no longer needs to maintain the muscle mass and strength that is not being utilized. Additionally, excessive reliance on walkers can cause individuals to neglect the importance of daily exercise and rehabilitation training, further weakening their muscle strength and coordination.
To mitigate the potential for muscle atrophy, individuals using walkers should incorporate muscle-strengthening exercises and aerobic activities, such as walking, cycling, or swimming, into their routines. Intermittent practice of unassisted walking can also help increase muscle activity and prevent atrophy. It is important for walker users to work with healthcare professionals to ensure proper use and maintain their physical health.

Long-term reliance on walkers
Increased Dependence: Prolonged use of walkers may lead to increased reliance on the device, causing individuals, especially the elderly, to gradually lose trust in their body's abilities. This can result in a decrease in the body's self-regulation capabilities and further weaken muscle strength and coordination. To prevent this, it is essential to maintain muscle strength and flexibility through appropriate rehabilitation training and exercise plans, preferably under professional guidance.
Muscle Atrophy: By providing external support, walkers reduce the need to mobilize muscles during walking, which can lead to muscle atrophy, or muscle wasting and thinning. This is because the body starts breaking down muscles that are not used, leading to a decrease in muscle mass and strength. To prevent muscle atrophy, individuals should engage in muscle-strengthening training and aerobic exercises, such as walking, cycling, or swimming, alongside unassisted walking practice to maintain muscle activity.
Poor Posture and Joint Pain: Improper use of walkers or using a walker that is not adjusted correctly to the user's height can lead to poor posture, including excessive bending, leaning forward, or leaning to the side. Maintaining such poor postures for extended periods can result in long-term back, neck, and shoulder pain. Ensuring that the height and handle position of the walker are suitable for the user is crucial to maintaining correct posture and avoiding joint pain.
Psychological Impacts: Long-term reliance on walkers may also have psychological effects, including anxiety and depression. This can be a result of the decreased independence and potential social isolation that may accompany prolonged walker use. It is essential to address these psychological impacts through comprehensive rehabilitation training and family or social support to maintain overall well-being.
It is important to note that the decision to use a walker should be made in consultation with a healthcare provider, who can help select the most suitable type of walker and provide guidance on its proper use to minimize potential side effects. Additionally, individuals should be encouraged to maintain physical activity and exercise routines, even when using a walker, to prevent muscle atrophy and promote overall health.

Muscle atrophy prevention methods
Muscle atrophy refers to the thinning or loss of muscle mass, which can be caused by muscle disuse, neurogenic conditions, malnutrition, ageing, genetics, or certain medical conditions. It can lead to a decrease in muscle mass, weakness, numbness, and tingling in the limbs, and can make daily activities challenging. While muscle atrophy can be a natural part of ageing, it can also occur due to prolonged periods of inactivity, such as during illness or injury recovery.
Using a walker can cause muscle atrophy in the lower limbs due to reduced muscle activity. This is especially true for four-wheeled walkers (rollators) which have been shown to significantly reduce lower-limb muscle activity in healthy subjects. This reduction in muscle activity could potentially lead to muscle atrophy over time. Therefore, it is important to consider muscle atrophy prevention methods when using a walker. Here are some ways to prevent muscle atrophy:
Exercise and Physical Therapy:
- Any amount of exercise is beneficial, even if it is just simple movements. Safe exercises for seniors can include practising getting off the floor to improve flexibility, balance, coordination, and muscle power.
- Strength training and aerobic exercise can help prevent muscle atrophy by maintaining muscle vitality and strength.
- Working with a physical therapist can be beneficial to develop a comprehensive program that includes strength training, cardio, and flexibility exercises.
Nutrition:
- Malnutrition can contribute to muscle atrophy, so ensuring a healthy diet is important.
- A nutrition plan that includes adequate protein and calories can help rebuild lost muscle mass.
Minimise Inactivity:
- Prolonged periods of inactivity can accelerate muscle loss, leading to atrophy. Therefore, it is important to minimise inactivity whenever possible.
- If using a walker, ensure that it is properly adjusted to your needs and that you are using the correct technique to prevent falls and injuries. This can help you maintain your mobility and independence.
Address Underlying Conditions:
- Muscle atrophy can be caused by certain medical conditions, such as neurological diseases or cardiopulmonary conditions.
- Treating or managing these underlying conditions can help prevent muscle atrophy. For example, rollators can be used to improve walking endurance and muscle strength in patients with neurological diseases.
It is important to consult with a healthcare provider to determine the best prevention and treatment plan for muscle atrophy. They can provide personalised recommendations based on your specific needs and underlying conditions.

Poor posture and joint burden
To avoid poor posture, it is essential to adjust the height of the walker to the user's height. The handles of the walker should be at the same height as the user's wrists when their arms hang naturally at their sides. If the handles are too high or too low, it can cause discomfort and lead to poor posture. Additionally, users should maintain good posture while walking, including standing tall with their head up and looking straight ahead.
Incorrect usage of a walker can also lead to an increased joint burden. For example, using a rollator walker on uneven ground or ramps can increase the burden on the joints, especially the knee and hip joints. This can lead to joint fatigue and pain over time. Therefore, it is recommended to use a walker on flat and safe ground whenever possible.
Furthermore, long-term reliance on a walker can lead to a decrease in the body's self-regulation ability and increased dependence on the device. This can cause individuals to neglect daily exercise and rehabilitation training, further weakening muscle strength and coordination. To avoid this, it is important to maintain muscle strength and flexibility through appropriate rehabilitation training and exercise plans, preferably under the guidance of a doctor or physical therapist.
Overall, while poor posture and joint burden can be potential side effects of using a walker, these issues can often be mitigated through proper usage, adjustment, and rehabilitation training. It is important to work with a physical therapist to improve balance and posture while using a walker and to maintain muscle strength and flexibility.

Psychological effects of walker use
Walker use has been associated with lower self-perceptions of physical functioning, role limitations due to physical problems, and general health in assisted-living residents. This perception of decreased mobility can result in lower self-esteem and a poorer sense of identity and self-worth, which can lead to a withdrawal from social interactions.
The use of a walker can also be a psychological barrier, affecting an individual's mental health and well-being. This can lead to a fear of falling, causing stress and avoidance of activities, which can have a knock-on effect on overall health.
However, walker use can also have positive psychological effects. For example, it can give users the confidence to take part in activities and increase social contact, which can have a positive impact on overall health. Additionally, the use of a walker can reduce the fear of falling, which can be a psychological barrier to engaging in activities.
Furthermore, leisure walking, which is a form of physical activity accessible to older adults, has been found to have substantial psychological benefits. It can reduce depressive symptoms, increase positive feelings and emotions, and improve mental health. It can also reduce the severity of pain and levels of stress and anxiety.
Therefore, while walker use may have some negative psychological effects, it can also enable individuals to maintain their independence and engage in activities that can have positive psychological benefits.
