Muscle weakness and stiffness are common after a brain injury and can make everyday movement harder. This article explains why these changes happen, how they can affect mobility and independence, and how brain injury physiotherapy may support recovery. It also looks at the specialist neurological rehabilitation offered by NeuroABLE Physiotherapy, part of Health on High in Coffs Harbour.
Muscle weakness and stiffness are among the most common physical changes people notice after a brain injury, and they can affect mobility, balance and everyday activities such as walking, dressing or moving from sitting to standing. These changes can feel frustrating and, at times, overwhelming, whether you are navigating them yourself or supporting someone you love. You do not have to face them alone. This is where brain injury physiotherapy can help. Every recovery is different, depending on the nature and severity of the injury, so there is no single timeline or path that fits everyone. Physiotherapy is one important part of a broader rehabilitation approach that may support movement, function and independence over time.
NeuroABLE Physiotherapy, part of Health on High, provides specialist neurological physiotherapy for people living with brain injury and other complex neurological conditions in Coffs Harbour. This article looks at why muscle weakness and stiffness develop after a brain injury, how they can affect daily life, and how a tailored physiotherapy program may support recovery.
Understanding How a Brain Injury Affects Movement
A brain injury can affect the parts of the brain that plan, control and coordinate movement. According to Healthdirect, an acquired brain injury can cause a range of effects, including muscle weakness, and the way it affects each person depends on which areas of the brain are involved.
How a Brain Injury Can Affect the Nervous System
The brain sends and receives the signals that tell your muscles when and how to move. When a brain injury disrupts these pathways, the messages between the brain and body can become weaker, slower or harder to coordinate. This can change how muscles work, how they respond to movement and how well different muscle groups work together.
Common Physical Challenges During Recovery
Physical changes after a brain injury vary widely from person to person, and it is completely understandable to feel unsettled when your body no longer responds the way it used to. Common challenges can include reduced strength, changes in muscle tone, difficulty with balance and coordination, fatigue and altered movement patterns. These changes can make familiar tasks feel more effortful, which is why structured rehabilitation after brain injury can be so valuable.
Muscle Weakness After a Brain Injury
Why Muscle Weakness Develops
Muscle weakness after a brain injury often relates to disrupted signalling between the brain and muscles, rather than a problem with the muscle itself. Reduced activity during recovery, time spent resting and changes in the way the nervous system activates muscles can all contribute to a loss of strength.
How Weakness Can Affect Daily Life, Mobility and Independence
Weakness can make simple movements harder, from standing up and walking to climbing stairs or carrying items. It can affect balance and increase the effort needed for transfers, such as moving between a bed and a chair. Over time, this can influence a person’s confidence, independence and ability to take part in the activities that matter to them. Targeted strengthening is a key focus of physiotherapy for this reason.
Muscle Stiffness and Changes in Muscle Tone
Understanding Stiffness and Spasticity
Many people notice stiffness after a brain injury. In some cases this is related to spasticity, where muscles become overactive and tighten involuntarily. Spasticity can cause muscles to feel tight or resistant to movement and, if it is not managed, it can contribute to discomfort and reduced range of motion.
How Increased Muscle Tone Can Affect Movement
Increased muscle tone can make it harder to move a limb through its full range, affect posture and interfere with daily tasks. Stiffness commonly affects areas such as the arms, hands, legs and ankles, and it can change the way a person walks or holds their body. Physiotherapy aims to manage this stiffness and support more comfortable, functional movement.
Other Physical Symptoms That Can Affect Recovery
Alongside weakness and stiffness, a brain injury can bring other physical changes that influence rehabilitation, including:
- Reduced balance and coordination, which can affect standing, walking and confidence on uneven surfaces
- Fatigue during physical activity, meaning energy often needs to be managed carefully across the day
- Changes in posture and movement patterns, as the body adapts to weakness or stiffness
- Reduced endurance and physical capacity, so activity is usually built up gradually
Recognising these symptoms helps a physiotherapist design a program that is realistic, safe and paced to each person.
How Brain Injury Physiotherapy Supports Recovery
Assessing Strength, Mobility and Function
Physiotherapy begins with a thorough assessment of strength, movement, balance and how a person manages day-to-day tasks. This helps identify the specific challenges to focus on and provides a clear starting point to measure progress.
Setting Individualised Rehabilitation Goals
Goals are set together with each person and, where appropriate, their family or carers. Meaningful, personal goals, such as walking a certain distance or moving more easily at home, help guide the program and keep it focused on what matters most.
Developing a Personalised Treatment Plan
From there, the physiotherapist develops a plan matched to the person’s condition, ability and goals. The aim is not only to improve movement in the clinic, but to help people take part more fully in life at home, at work and in the community.
Physiotherapy Strategies for Weakness, Stiffness and Mobility
Managing Muscle Weakness
Strategies to address weakness may include strength and conditioning exercises, functional movement training and task-specific practice that rehearses real-life activities. Programs are progressed gradually so that muscles are challenged safely, without doing too much too soon. Where standing and weight-bearing are goals, a tilt table can support safe, graded weight-bearing for people who are not yet able to stand independently.
Managing Muscle Stiffness
Managing stiffness and spasticity may involve stretching and range of motion exercises, along with careful positioning and movement techniques that encourage muscles to lengthen and relax. A ceiling hoist can assist with safe transfers and positioning during therapy, so sessions stay comfortable and secure for people with significant mobility needs. Physiotherapy for spasticity is often most effective as part of a coordinated plan that may also involve medical management.
Improving Balance, Walking and Mobility
For many people, walking and balance are central goals. Physiotherapy may include gait retraining, balance and stability exercises, and practice with transfers and functional mobility, with or without assistive devices. As skills improve, the focus shifts to building confidence in movement so that gains carry over into everyday life.
The Importance of Ongoing Rehabilitation
Recovery after a brain injury is rarely a straight line, and improvements can continue over an extended period. Rehabilitation goals are reviewed and adapted as a person progresses, so the program continues to challenge them appropriately and support long-term physical function. For progressive or complex conditions, ongoing physiotherapy also plays an important role in maintaining mobility, comfort and independence for as long as possible.
The Role of Multidisciplinary Care in Brain Injury Rehabilitation
Brain injury rehabilitation often works best when several allied health professionals work together. Working independently but as part of the multidisciplinary Health on High group allows these experienced Allied Health Professionals to streamline referrals and communication, and to offer joint assessments across therapies for your convenience and benefit.
Depending on individual needs, this coordinated care may involve:
- Occupational therapy, supporting everyday function with practical strategies, assistive technology and equipment such as wheelchairs and seating
- Speech pathology, helping with communication, including alternative communication methods, and with the assessment of swallowing and meal planning where needed
- Exercise physiology, supporting strength, conditioning and long-term physical activity as recovery progresses
Bringing these services together means a person’s physiotherapy can complement the rest of their care, with everyone working towards the same goals.
When to Seek Physiotherapy After a Brain Injury
It is not always easy to know when to reach out for help, and many people wait longer than they need to. It can be worth speaking with a physiotherapist if you or someone you support is experiencing:
- Changes in strength or mobility
- Difficulty walking or maintaining balance
- Increasing muscle stiffness or tightness
- Challenges with day-to-day activities and independence
Early, individualised support can help people work towards their goals safely and make the most of their recovery.
