"How long will it take before the patient can walk again?" This is the question families of almost every patient with a moderate stroke most want answered. Fortunately, at the moderate stage regaining the ability to walk is a realistic goal. What decides the pace of recovery is not some special piece of equipment but the amount of correct, task-oriented practice, which is the conclusion that many clinical studies share. This article first answers the questions families care about most, the timetable and the chances of recovery. It then looks at which kinds of training give the most benefit, and finally describes lower limb training techniques that suit the home setting.
Stages of walking recovery after a moderate stroke
Patients with a moderate stroke can usually stand, but still have difficulty walking and keeping their balance. This stage is critical because the nervous system is in its golden period of relearning. The Hong Kong Society for Rehabilitation notes that the first 6 months after a stroke are the "golden period" of recovery. Physiotherapy uses the brain's "neuroplasticity" to help the patient regain control of the lower limb and then walk again.
What should be done most in this critical period? Large evidence-based studies give a fairly consistent answer: the biggest controllable factor in recovery is the amount of practice. Veerbeek and colleagues (2014) pooled 467 randomised controlled trials covering more than 25,000 patients and found that the higher the practice dose, the better the recovery of lower limb and motor function (effect sizes of about 0.21–0.61). Evidence was strongest and most plentiful for task-oriented, fitness and gait training. The American Heart Association/American Stroke Association rehabilitation guideline (Winstein et al., 2016) also states clearly that rehabilitation needs enough "dose and duration", and that repetitive, task-oriented practice is the core of regaining motor ability.
In short: at the moderate stage, what is most worth investing in is not buying equipment but making sure that movements are done correctly and practised enough. Repeating useful training movements often enough is the key to regaining the ability to walk.
Clinical research data on lower limb training outcomes
There is no absolute timetable for recovering the ability to walk, but clinical evidence shows how much change the right training can bring. The data below come from high-quality studies of walking ability in stroke patients and are given for families as a practical reference.
These figures have one thing in common. They all come from training that "repeats real functional movements", and not from simple strength exercise or passive treatment. In other words, to improve walking, choosing the right direction matters more than looking for fancy equipment. The right way is to turn everyday movements such as standing, sit-to-stand and stepping into enough repetitions with correct posture. The sections below go through the training items most worth prioritising.
Sit-to-stand training
If only one lower limb exercise can be chosen at the moderate stage, sit-to-stand is almost always the first choice. There are two reasons. It is the movement done most often in daily life, and it builds the strength and balance that carry over most directly to walking.
More importantly, the threshold for sit-to-stand practice is lower than many people think. A randomised controlled trial by de Sousa and colleagues (2019) found that stroke patients who "cannot yet stand up independently"improved clearly in their ability to stand up (global rating of change) and in lower limb extensor strength after two weeks of two extra sessions a day of intensive sit-to-stand training on top of usual treatment. This study challenges the belief that a patient must be able to stand steadily before practising sit-to-stand. Sit-to-stand practice itself is an effective way to help the patient "practise until able to stand up".
Training works even better with immediate visual feedback. Hyun and colleagues (2021) had patients do sit-to-stand training on a balance board for 20 minutes, 5 times a week for 6 weeks. The patients did better than with conventional sit-to-stand training on the Berg Balance Scale (37.2 to 51.3), the Timed Up and Go test (TUG, 20.7 to 16.7 seconds), the 10-metre walk and knee extensor strength (all between-group differences were significant). This gives solid scientific grounds for the mirror/feedback weight-shifting practice mentioned below.
Suggestion for home practice: sit-to-stand should be treated as the main exercise to be done every day. Prepare a stable chair with armrests, and make sure the affected leg is firmly on the floor and working together with the unaffected leg. Practising in front of a mirror shows whether the body leans to one side or is uneven when standing up, which makes the posture clear. The specific steps are given below under sit-to-stand training.
Task-oriented training and circuit training
Sit-to-stand is only the starting point. To get the most out of rehabilitation, use task-oriented and circuit classtraining to build up "effective repetitions" in a planned way.
Task-oriented training is built on repeated practice of real functional movements. Lee and Lee (2025) pooled 17 randomised controlled trials (888 patients in total) and found that this approach significantly improved walking speed (SMD 0.48), walking endurance (SMD 0.49) and Berg balance score (SMD 0.45). Circuit training links several training stations with different tasks, so that the patient completes more repetitions within one session. The Cochrane review by English and colleagues (2017) (17 RCTs, 1,297 patients, moderate-quality evidence) showed that circuit training increased the 6-minute walk distance by about 60.9 m and walking speed by 0.15 m/s.
Features of task-oriented training
- All the practice is real movement used in daily life, such as standing up, stepping, turning and going up and down stairs.
- Each practice has a clear everyday goal, such as walking to the kitchen or to the toilet.
- The difficulty rises step by step with the patient's ability, so that the challenge stays suitable.
- The training focuses on the number of repetitions and the quality of movement, not on exercising a single muscle in isolation.
Benefits of circuit (station-based) training
- Practising at several stations in turn allows more repetitions within one session.
- One session can train standing, balance, stepping and endurance at the same time.
- Alternating different movements is less dull, which helps the patient stay motivated to practise over the long term.
- The therapist can design the content first, and family members can then help the patient practise beside the patient in daily life.
The amount of practice matters more than equipment: the principle behind both task-oriented and circuit training is the one that Veerbeek (2014) pointed out, that the more is practised, the greater the improvement. Equipment is only a helping tool. What really helps the body recover is repeating the correct everyday movements enough times.
Who treadmill and body-weight support training suits
Many families think that buying a treadmill or a body-weight support treadmill will help the patient walk again sooner. Whether this equipment is suitable actually depends on the patient's present ability. The Cochrane review by Mehrholz and colleagues (2014) pooled 44 trials with 2,658 patients and found that treadmill training with body-weight support gave only a slight gain in walking speed (+0.07 m/s) and endurance (+26.4 m).
An important distinction: the same Cochrane review notes that treadmill training mainly helps patients who "can already walk", and the effect is not clear for patients who "cannot yet walk independently". In other words, if a patient with a moderate stroke is still practising standing steadily and shifting weight, a treadmill is not a shortcut at this stage.
A more realistic order of training is therefore to build the base first through sit-to-stand, standing weight bearing, weight shifting and task-oriented practice. Once the patient can step steadily with someone's help, a treadmill can play a supporting role. A physiotherapist should also assess the patient before use, to make sure the training is safe and set up properly.
Standing training
Standing training is a core part of rehabilitation after a moderate stroke. Improving standing posture and building balance lay a solid base for later walking training.
Weight bearing on the affected side
After a stroke, patients often shift most of their weight onto the unaffected side without realising it. In the long run this causes the muscles on the affected side to keep wasting and balance to decline. The aim of weight-bearing training is to guide the affected leg to take more weight and change the habit of leaning on the unaffected side.
Training method: the therapist uses manual guidance (handling) to help the patient feel how to put body weight firmly on the affected leg. Training usually starts with the affected leg taking 50% of body weight and gradually increases to 70–80%. Practising in front of a mirror also lets the patient see whether the standing posture is symmetrical.
Gaiter knee brace: if the patient's knee is not yet strong enough to control, a Gaiter (knee brace) can be considered to hold the knee joint, so that the patient feels more confident putting weight back onto the affected leg.
Dynamic balance control
Standing steadily on the spot is only the first step. The real challenge is keeping balance while moving the body's centre of gravity. This is a basic requirement for walking, and the aim of training is for the patient to learn to shift weight freely while standing.
Standing weight shift
- While standing, slowly shift body weight from the unaffected leg to the affected leg.
- Hold the weight on the affected leg for 3–5 seconds, then slowly shift back.
- The goal of practice is to be able to support the body on the affected leg alone.
Upper body movement while standing
- While standing, move the hands and upper body in different directions.
- For example, bend the upper body forward and then stand up straight again.
- The goal of practice is to keep balance throughout while the upper body moves.
Safety reminder: when doing this kind of dynamic balance practice, there must be a steady handrail beside the patient or a therapist supervising and helping, to prevent falls. Practising to take weight evenly on both legs also helps prevent falls in itself. Cheng and colleagues (2001) found that symmetrical weight-bearing training can reduce the chance of falls in stroke patients. Learning to put weight evenly back onto the affected leg is therefore both the basis of walking and a safeguard.
Sit-to-stand exercises
Sit-to-stand is one of the movements done most often in daily living. Training this ability well greatly improves the patient's self-care and independence.
Sit-to-stand training
Sit-to-stand is the most effective movement for strengthening the quadriceps and hip muscles, and it is the core training mentioned earlier as giving the most benefit and being possible to start early (de Sousa 2019). The standard steps are as follows.
- 1Sit at the front of the chairFirst move the buttocks to the front third of the seat.
- 2Draw both feet backPull the heels back so that the feet are directly under the knees.
- 3Lean forwardLean the upper body forward so that the tip of the nose goes past the front of the toes.
- 4Lift off and standUse the strength of both legs to push the body up and stand.
Training points: when standing up, make sure the affected leg is firmly on the floor and working together with the unaffected leg. Do not rely only on the unaffected leg, or the body easily leans to one side when standing. Do 10 repetitions per set and 3 sets a day.
Mini squats
Small squats and stands from a standing position are an ideal way to strengthen the quadriceps and train eccentric control of the muscle, which helps knee control.
Correct method
- Hold a fixed support firmly with both hands.
- Bend the knees slightly, about 20–30 degrees.
- The knees bend in the same direction as the toes point.
- Squat down slowly and stand up slowly.
- 10–15 repetitions per set
Common mistakes
- The knees collapse inwards (the two knees knock together).
- The upper body leans too far forward
- The ankles are stiff and do not bend at all.
- Only the unaffected leg works to support the body.
Pre-gait training
Before starting to walk, the patient first needs to master the separate components of walking in order to build a correct gait pattern.
Exercise 1: marching on the spot
This practises control in lifting and lowering the affected leg.
Key points
- Hold a steady support (for example a walking frame) with both hands.
- First practise lifting the unaffected leg, so that the affected leg takes the weight alone.
- Then practise lifting the affected leg while keeping balance.
- The goal is to lift the affected leg steadily 10 times.
Purpose
- This trains stability on one leg and imitates stepping on one leg while walking.
Exercise 2: stepping forward and back
This imitates stepping forward and backward in real walking.
Key points
- Step the affected leg forward a short way, then return it to its original position.
- Step the affected leg back a short way, then return it to its original position.
- While stepping, keep the upper body steady and avoid swaying from side to side.
Purpose
- This practises shifting weight forward and backward and builds control of the lower limb.
Exercise 3: side stepping
This strengthens the hip abductors and improves stability when moving sideways.
Key points
- Step the affected leg out to the side.
- Bring the unaffected leg across straight away so that the feet are side by side.
- Then practise in the opposite direction, with the unaffected leg stepping out to the side first.
Purpose
- This trains sideways balance and lowers the risk of falling during everyday walking.
Progress gradually: pre-gait training should go from easy to hard. At first the patient can lean on a steady handrail, then gradually use the hands less. Once the patient can do the separate movements above steadily, the patient can move on to real walking training.
Core training
Strong core muscles are the base for standing and walking. The following exercises help improve trunk control and pelvic stability.
Bridging
- Starting position: lie on the back with both knees bent and both feet firmly on the bed
- Movement: tighten the buttocks and lift the pelvis off the bed, holding for 5 seconds
- Repetitions: 10 per set, 3 sets a day
Dynamic sitting exercises
- Weight shifting: sit on a chair and lean the body forward, back, left and right
- Reaching: reach in different directions to touch a target
- Trunk rotation: keep the pelvis steady and turn the upper body left and right
Pelvic control exercises
- Anterior pelvic tilt: push the lower back forward to increase the curve of the lumbar spine
- Posterior pelvic tilt: flatten the lower back against the bed or chair back
- Lateral pelvic tilt: raise the left and right hip bones alternately
Stretching
Preventing muscle contracture and joint stiffness and keeping soft tissue supple is an essential part of rehabilitation. The stretches below are for the main muscle groups of the lower limb.
Calf muscle (gastrocnemius)
- Step the affected leg back, with the heel flat on the floor.
- Bend the front knee slightly and keep the back leg straight.
- Feel a pull and stretch at the back of the calf.
- Hold for 30 seconds and repeat 3 times.
Hamstrings
- Sit at the front of a chair and straighten the affected leg forward.
- Keep the heel on the floor and the toes pointing up to the ceiling.
- Slowly lean the upper body forward and feel the stretch at the back of the thigh.
- Hold for 30 seconds and repeat 3 times.
Hip flexors (iliopsoas)
- Stand steadily first, then step the affected leg a long way back.
- The knee of the back leg can lightly touch the floor.
- Keep the upper body upright and slowly push the pelvis forward.
- Feel the stretch at the front of the top of the thigh (the front of the hip joint).
Adductors
- Sit steadily and open both legs out to the sides.
- Slowly lean the upper body forward.
- Feel the stretch in the muscles of the inner thigh.
- Hold for 30 seconds and repeat 3 times.
Stretching principles: hold each stretch for 30 seconds and repeat it 3 times. The muscle should feel only mildly tight and must never hurt. Move slowly and steadily, and do not bounce or pull hard. The best time to stretch is after exercise or after a bath, when the muscles are warm.
Neuromuscular electrical stimulation (NMES)
This therapy uses a small electrical current to help wake up muscles that are not working and speed up rebuilding the link between nerve and muscle. When the brain is damaged by a stroke and cannot send commands to the muscle effectively, NMES can directly stimulate the muscle to contract, so that the patient can "feel" again what it is like for the muscle to work properly. It is as if the current temporarily "replaces" the brain in giving commands, which encourages the nerve pathway to rebuild.
When it is suitable
- For patients whose muscles are not strong enough but who still have some sensation.
- For patients who want to strengthen the contraction of a particular muscle group.
- The effect is better if the patient also works the muscle voluntarily while the current is on.
Common treatment sites
- Quadriceps (front of the thigh).
- Tibialis anterior (front of the lower leg); stimulating this muscle helps with foot drop.
- Gluteus maximus; stimulating this muscle can strengthen backward extension of the thigh (hip extension).
Treatment process: the therapist first places electrode pads on the target muscle and then slowly adjusts the current until the muscle visibly contracts. Each treatment lasts about 15–20 minutes. The ideal approach is for the patient to try to contract the muscle voluntarily at the same time as the device delivers the current.
Precautions: electrical stimulation must never be used by patients with a cardiac pacemaker. It must also not be used over a wound or an area with inflammation or infection. The treatment should not be painful, and the patient should feel only a mild tingling.
Proprioceptive neuromuscular facilitation (PNF)
This technique uses specific hands-on skills and movement patterns to stimulate the nervous system, in order to restore muscle strength and coordination. PNF is a specialised neurological rehabilitation technique. The therapist uses specific resistance, stretch and postural guidanceto stimulate the body's proprioceptors and bring out stronger and better coordinated muscle contractions. The principle is like waking up the nerve response through movement patterns from many angles.
Common techniques
- Rhythmic initiation - progressing from passive to active
- Reversal of antagonists - alternating contraction of opposite muscle groups
- Contract-relax - increasing joint range of motion
- Stabilising reversals - increasing joint stability
Treatment effects
- Improves muscle strength
- Improves coordination of movement.
- Increases the range through which the joints can move.
- Helps the nervous system regain control of the muscles.
Diagonal movement patterns for the lower limb in PNF: PNF moves the limb along diagonal and spiral paths (for example the D1 and D2 patterns). These movement paths are closer to the natural movements of daily life, such as the direction in which the legs swing when walking.
Treatment process:this technique must be carried out by a physiotherapist with the relevant training. According to the patient's condition, the therapist applies suitable resistance and direction by hand, while the patient also works actively at the same time. The technique is usually used together with other rehabilitation training.
