Lower-Limb Physiotherapy After Severe Stroke: An Evidence-Based Guide to Protecting Function in the Bedbound Phase

Families caring for a bedbound relative after severe stroke are often caught between two worries. One is that "too little training will lead to decline", and the other is that "pushing too hard will hurt the patient". Most information in circulation simply urges "get the patient standing as soon as possible", and seldom says clearly that getting the patient up earlier and doing more training does not necessarily give better results. In patients with severe stroke (such as severe hemiplegia, older adults who are bedbound for a long time), the lower limb can hardly move actively, and the real task of physiotherapy at this stage is not to blindly "push the amount of training" but to protect function precisely: to keep joint range of movement and muscle with a suitable dose, to prevent the most dangerous complications, and to lay the groundwork for later rehabilitation. Based on clinical evidence, this article goes through the dose principles in the bedbound phase, the truth about preventing contracture, and the hidden killer that is most easily overlooked.

Key points of physiotherapy in the bedbound phase of severe stroke

Many people instinctively think that "the earlier the start after a stroke and the more training the better", but the highest level of medical evidence at present reaches the opposite conclusion. Recognising this lets the limited caring time be used well.

A common myth: is getting up earlier and training more always better?

This does not argue for "no movement at all". The real message of the AVERT study is that intervention should start early, but in a low-dose, short and frequentpattern, and not as long and intensive drills. The right approach is frequent changes of position together with small amounts of activity, with the registered physiotherapist deciding when to start and how much to do each time according to the patient's vital signs, state of consciousness and NIHSS score.

Dose principles in the bedbound phase

Three treatment goals in the bedbound phase

Under the dose principles above, the core of treatment for a patient with severe stroke revolves around four directions: preventing complications of bed rest, inducing neuromuscular activity, establishing early lower-limb weight bearing, and easing the carer's daily burden.

The risk of deep vein thrombosis (DVT) in the bedbound phase

For stroke patients who cannot walk at all, the complication most often overlooked but most dangerous is not "muscle wasting and decline" but deep vein thrombosis (DVT)and the pulmonary embolism it causes. In the bedbound stage, the "preventive" role of physiotherapy often comes in earlier than "rehabilitation exercises" and is more important.

The CLOTS 3 multicentre RCT (94 centres in the UK, 2,876 stroke patients in the acute phase who could not walk) showed that intermittent pneumatic compression (IPC, that is, inflatable leg sleeves) significantly lowers the risk of proximal DVT and tends to improve survival. A later stratified analysis went further and showed that the worse the prognosis, the greater the benefit, with only about the best-prognosis one fifth of patients gaining little (CLOTS Trials Collaboration, 2013; Dennis et al., 2015).

The preventive role of physiotherapy: ankle pumps, promoting circulation and IPC compression

Physiotherapy equipment and pain management

Before exercise training, physiotherapy equipment can first be used to improve the state of the muscle or ease high tone. Electrical stimulation (ES) is a supporting tool often used in the severe stage of stroke.

What electrical stimulation can actually do, and its limits (the objective boundary of FES)

The real value of electrical stimulation for patients with severe stroke must be defined accurately. Overall, electrical stimulation together with usual rehabilitation training can improve ankle dorsiflexion range and lower-limb motor function in patients with foot drop (a network meta-analysis pooling 37 RCTs with 2,309 people showed the best effect in the recovery period 1–6 months after onset) (Wang et al., 2025). For the clinical evidence and specific use of NMES / FES, see the evidence and use of electrical stimulation (NMES / FES) after stroke explained in detail. However, the early benefit of FES shows mainly in raising strength and rebuilding neural connections, and not in speeding up walking at once. A crossover RCT found that although FES strengthened the foot dorsiflexors and induced a measurable change in the latency of SEP (somatosensory evoked potentials), which represents a neuroplasticity signal, there was no significant difference in the "time" needed for a 10-metre walk (Mijic et al., 2023).

Proprioceptive neuromuscular facilitation (PNF)

For patients with severe weakness after stroke, the therapist can use PNF techniques to stimulate proprioception and so induce correct movement patterns. Among these, pelvic girdle PNF is an important cornerstone of lower-limb rehabilitation. An RCT pointed out that, when pelvic PNF was added to task-oriented training, patients with chronic stroke did significantly better than the group having task-oriented training alone in balance (mean difference of about 19 points between groups on the Berg Balance Scale, p<0.001) and in gait parameters (stride length from about 39 cm to about 57 cm) (Boob & Kovela, 2022).

Pelvic girdle PNF (Pelvic PNF)

This training is the foundation for movement in bed and for regaining gait later, and is extremely important. The therapist places both hands on the patient's pelvis and applies suitable resistance to guide movement in the two directions below.

Lower-limb D1 / D2 spiral diagonal patterns

Using "rhythmic initiation" step by step, the patient is guided to learn to pull the foot up while bending the knee:

1. 1
   Fully passive

   The therapist moves the patient's leg through the whole movement while the patient stays relaxed.
2. 2
   Active-assisted

   The patient tries to make an effort to go along with the movement, and the therapist slowly reduces the help given.
3. 3
   Resisted

   The therapist adds light resistance as the patient moves, to strengthen the effect of training and help the patient remember the right way to apply force.

Exercise training in bed

Exercise in bed is the basic training for the rehabilitation of a patient with severe stroke, helping to keep joint range of movement, strengthen core muscles and prepare for transfers later. As the patient's ability gradually improves, the patient can go on to learn independent transfer skills between bed, wheelchair and toilet, which eases the physical burden on carers.

Sitting at the edge of the bed (Edge of Bed Sitting)

Sitting at the edge of the bed is an important bridge from lying to sitting up, and the basis of all transfer training.

Bridging exercise (Bridging Exercise)

The bridge is a classic exercise for strengthening the gluteal and lower back muscles, and is very important for moving in bed and for daily transfers.

1. 1
   Starting position

   The patient lies flat on the back (supine) on the bed, with both knees bent and both feet flat on the bed.
2. 2
   Lift the pelvis

   Tighten the gluteal muscles and lift the buttocks up off the bed.
3. 3
   Hold and lower

   Hold at the top for 3–5 seconds, then slowly lower the buttocks back to the bed.

Rolling over in bed (Rolling)

Rolling over in bed is one of the most basic movements of daily life, and also a key skill for preventing pressure sores.

Why daily stretching alone is not enough to prevent joint contracture

"If I stretch the patient every day, will that stop the joints stiffening into contracture?" This is the expectation carers hold most often, but the medical evidence gives a negative answer. Patients with severe stroke, being bedbound for a long time, do tend to have shortened muscles. Stretching has its role, but it cannot be relied on alone.

The combination that truly prevents contracture: weight-bearing standing, a night AFO and full-range joint movement

The key to preventing and improving contracture is to stretch the soft tissues in a sustained, low-load and long-duration way, and not by brief, forceful stretching. Combining the three measures below is the evidence-supported strategy for preventing contracture:

Note: specific stretching techniques are listed below for carers and therapists to refer to when carrying out joint movement as part of the "combined strategy". Please remember that stretching is only part of the whole strategy.

Hamstring stretch (Hamstring Stretch)

If the hamstrings shorten, they limit straightening of the knee and bending of the hip, and so affect sitting and standing in daily life.

Calf stretch (Calf Stretch)

Shortening of the calf muscles (including gastrocnemius and soleus) leads to "foot drop", which stops the foot lying flat on the floor in standing and seriously affects the walking pattern.

The effects and timing of standing frame and standing aid training

Even when the patient cannot stand alone at all, passive standingin a standing frame remains an important supporting measure in the rehabilitation of severe stroke, and brings benefits in many physiological areas. It must be made clear, however, that a standing frame is a "good helper" with evidence behind it, and is not a "cure-all" that necessarily improves motor function.

In the hospital inpatient setting, a mechanical tilt table that combines tilted standing with rhythmic stepping (such as Erigo) has shown some potential for improving lower-limb strength, NIHSS score and quality of life in patients with acute stroke (Kumar et al., 2020). It should be noted, however, that such large equipment differs from an ordinary home standing frame and cannot be provided by home physiotherapy.
