In approximately 79 % of all stroke cases, a blood vessel that supplies the brain is blocked, e.g. by a blood clot. This results in an insufficient blood supply. Nearly 13 % of patients suffer exactly the opposite, namely bleeding in the brain, due to damaged vessels. In both cases, the supply of blood to certain regions of the brain is no longer sufficient due to a local circulatory disturbance.
But even if treatment is given very quickly, two thirds of stroke survivors sustain some damage. The good news is that the brain is capable of regenerating. Slightly damaged cells can be partially, or in a best-case scenario, completely restored. With specific training, other healthy nerve cells can also assume their function. This is called neuroplasticity.
The symptoms of stroke can vary widely between individuals, also in regards to their severity. They include:
- Impaired vision
- Restricted field of vision
- Disruptions of depth perception, seeing double
- Speech and language comprehension disturbances
- Paralysis, numbness
- Disrupted touch sensation
- Drooping corner of the mouth – such dysfunctions can also occur in the leg and arm (drop foot and wrist drop)
- Shoulder pain
- Unstable knee joint function while standing
- Torso instability
- Dizziness with uncertain gait
- Spasticity of various forms and severity
According to the federal rehabilitation workgroup, what is known as a phase model applies in the field of neurological rehabilitation. Initially the patient's need for help is assessed by the attending doctor and therapist. A certain rehabilitation phase can be considered depending on the patient's need for help. Neurological rehabilitation is divided into the following phases:
- Phase A: Acute medical treatment
- Phase B: Medical-therapeutic rehabilitation, early rehabilitation (in part still with the most severe limitations (coma) for most severely affected patients, whose ability to participate in treatment is limited)
- Phase C: Medical-therapeutic rehabilitation, (impairment of self-sufficiency)
- Phase D: Medical-therapeutic rehabilitation (movement possible at the ward level)
- Phase E: Medical-occupational rehabilitation (reintegration, reorientation if applicable)
- Phase F: Curative care, measures to maintain the current condition
A lot has been accomplished in acute care in recent years. With modern medical devices, Ottobock pursues the goal of focusing more on rehabilitation that follows acute patient care. From wheelchairs to provide support in the early rehabilitation phase, to products for dorsal flexor weakness (orthoses, functional electrical stimulation (FES) in the form of surface stimulation or as an implant) to orthoses that stabilise the shoulder, knee and wrist joint, Ottobock offers a broad portfolio of modern product solutions.
Stroke patients typically experience impairment of mobility in the shoulder, hand, knee and foot. Often one side of the body is completely or partially paralysed and has sensory deficits. The following medical devices were developed especially for stroke patients. They are designed to help you be more active, more independent in your daily life, and continue to develop dexterity and muscle strength. Many devices also relieve pain and protect against uncontrolled movement.
The products shown are fitting examples. Whether a product is actually suitable for you and whether you are capable of exploiting the functionality of the product to its fullest depends on many different factors. Amongst others, your physical condition, fitness and a detailed medical examination are key. Your doctor or orthopaedic technician will also decide which fitting is most suited to you. We are happy to support you.
