Introduction

After a stroke, many survivors experience a frustrating and often painful condition: involuntary muscle stiffness in the arm, combined with tight tendons and significant weakness. This stage of recovery, often referred to as stage 2 post‑stroke, presents unique challenges. The affected arm may feel heavy, difficult to move against gravity, and even a simple action like shrugging the shoulder can produce only a faint muscle contraction. Movements are weak, and the arm may resist being stretched or positioned.

For individuals living with these symptoms, the fear of further injury or the discouragement of slow progress can lead to reduced activity. However, consistent, gentle exercises performed at home are one of the most effective ways to regain range of motion, reduce stiffness, and rebuild the neural pathways that control arm movement. This article provides a detailed, practical guide to a set of safe, therapist‑approved exercises designed specifically for stroke survivors with arm stiffness and weakness. These exercises focus on supporting the affected arm, protecting vulnerable joints—especially the shoulder—and gradually reintroducing natural movement patterns needed for daily self‑care tasks such as combing hair, brushing teeth, eating, and dressing.

Understanding Stage 2 Stroke and Arm Stiffness

In the early weeks and months following a stroke, the brain begins a process of neuroplasticity—rewiring itself to compensate for damaged areas. During stage 2, muscles on the affected side may become hypertonic, meaning they remain in a state of increased tension. This manifests as stiffness in the muscles and tightness in the tendons. The arm may feel rigid, and passive movement (moving the arm with the help of the unaffected side) can meet resistance.

At the same time, active movement—the ability to initiate and control motion using the affected arm's own muscles—is very weak. Lifting the arm against gravity is particularly difficult. This combination of stiffness and weakness makes the arm feel "stuck." Without regular, gentle movement, the stiffness can worsen, leading to contractures (permanent tightening of muscles and tendons) and loss of joint mobility. Therefore, starting a home exercise program as soon as medically advised is crucial.

The exercises described below are appropriate for individuals who have been cleared by their medical team for passive and active‑assisted range of motion activities. They assume the survivor can sit upright with good trunk control or with minimal support. A sturdy dining table or similar surface is recommended for balance support during standing exercises.

Essential Principles Before You Begin

Support the affected arm with the unaffected arm.

Throughout most of these exercises, the unaffected (good) arm acts as a gentle helper. It supports the affected arm at the elbow and forearm, "babies" it through the movement, and prevents uncontrolled or jerky motions that could strain weak tissues.

Never force a movement.

Stiff muscles and tight tendons are vulnerable to tearing if stretched aggressively. All exercises should be performed slowly, gently, and within a pain‑free range. If a particular angle causes sharp pain, stop at that point and do not push further.

Protect the shoulder joint.

The shoulder is particularly vulnerable after a stroke because the muscles that normally stabilise the joint are weak. During exercises, avoid lifting the affected arm's elbow higher than shoulder level (past 90 degrees of abduction or flexion). This precaution reduces the risk of shoulder subluxation or impingement.

Use visual feedback.

Following the affected hand with your eyes—and turning your head to keep looking at the hand—helps the brain reconnect with the limb. This visual‑motor integration supports neuroplasticity.

Be patient with small gains.

Range of motion may improve only millimetres at a time. That is normal. Consistency matters more than intensity.

Exercise 1: Trunk Rotation

This foundational exercise improves the range of motion of the scapula (shoulder blade) and the shoulder joint itself. It does not require the arm to lift against gravity, making it safe and effective for early‑stage recovery.

Starting Position

Sit upright in a sturdy chair. Use your unaffected (good) arm to support your affected arm. Place your good hand under the elbow of the affected arm. Allow the rest of the affected forearm to rest on the forearm of your good arm. This creates a supportive "sling" using your own body.

Movement

Keeping your hips and legs stable, slowly rotate your trunk to the right, then to the left. The supported affected arm moves with your trunk. The good arm controls the speed and range.

Repetitions

🔄 10 alternating side‑to‑side rotations

Key Points

Move slowly. Feel the movement originating from your trunk, not just your arm. This exercise also gently stretches the chest and back muscles.

Exercise 2: Shoulder Rotation

This exercise directly addresses rotational movement at the shoulder joint. It helps counteract the inward rotation stiffness that often develops after a stroke.

Starting Position

Same supported arm position as in trunk rotation. The affected arm is cradled by the good arm, with the good hand supporting under the elbow and the good forearm supporting the affected forearm.

Movement – Outward Rotation

Using the good hand to guide, gently rotate the affected arm outward, away from the body. The palm may turn upward. Move only as far as comfortable, especially if the shoulder is painful. Perform 10 slow outward rotations.

Movement – Inward Rotation

From the starting position, guide the affected arm inward, crossing gently toward the midline of the body. Again, perform 10 slow repetitions.

Repetitions

🔄 10 outward + 10 inward rotations

Key Points

If any rotation causes a sharp pinch in the shoulder, reduce the range. The shoulder joint capsule may be tight, and forcing rotation can cause injury.

Exercise 3: Gentle Rocking Back and Forth

This preparatory exercise may seem simple, but it is essential for the next movement (diagonal reaching). It trains the trunk to lean forward slightly, which reduces the effective weight of the arm on the shoulder and makes lifting easier.

Starting Position

Sit or stand facing a sturdy table or countertop. If balance is an issue, stand in front of the table so you can rest your hands on it if needed. Support your affected arm with your good arm as before (good hand under the elbow, good forearm supporting the affected forearm).

Movement

Gently rock your whole body forward, then backward. As you lean forward, you will feel the affected arm move forward slightly. As you lean back, the arm follows. Try to go as far forward as you comfortably can, then lean back.

Repetitions

🔄 10 slow rocking cycles (forward and back = one cycle)

Key Points

Keep the movement smooth and rhythmical. Do not hold your breath. This exercise is not about the arm moving on its own—it is about using trunk motion to passively move the arm, which warms up the shoulder joint and improves blood flow.

Exercise 4: Diagonal Reaching (Two Directions)

Diagonal movements are fundamental to many daily self‑care activities. Reaching to comb hair, brushing teeth on the opposite side, eating from a plate, and putting an arm through a sleeve all involve diagonal patterns that cross the midline or go from low to high diagonally.

⚠️ Important precaution: Do not allow the elbow to rise higher than shoulder level during these reaches. Keep the elbow at or below shoulder height to protect the joint.

First Direction — Affected Side to Opposite Ear

Support your affected arm by holding the wrist with your good hand. Lean forward slightly (as practised in the rocking exercise). Begin with the affected hand down near your lap or the opposite hip. Slowly guide the hand diagonally upward toward your opposite ear (the ear on the unaffected side). Follow the hand with your eyes and turn your head to look at the hand as it moves. Then slowly lower back to the starting position.

🔄 10 slow reaches

Second Direction — Opposite Side to Same‑Side Ear

Again support the wrist with your good hand. Lean forward slightly. This time, bring the affected hand from the opposite side of your body (near the unaffected hip) diagonally upward toward the ear on the same side as the affected arm. Follow with your eyes and head. Lower back down.

🔄 10 slow reaches

Key Points

The lean‑forward motion is critical. It shifts the centre of gravity forward, reducing the effort required from the weakened shoulder muscles. If you cannot reach all the way to the ear, that is fine—reach only as far as you can without pain or forcing.

Exercise 5: Forearm Rotation (Pronation and Supination)

Turning the forearm so the palm faces up (supination) or down (pronation) is necessary for grasping and releasing objects. After a stroke, this movement often becomes stiff and limited. This exercise should be performed on a table at a comfortable height, such as a dining table.

Starting Position

Sit at a table. Rest your affected forearm on the table, with the elbow bent at approximately 90 degrees and the hand extending just beyond the table edge. Your unaffected hand will guide the movement. Place your good hand gently over the affected hand or around the wrist.

Movement – Facing Up (Supination)

Use your good hand to slowly turn your affected palm upward, as if you are holding a bowl of soup. Go only as far as comfortable. Then return to neutral.

Movement – Facing Down (Pronation)

From neutral, turn the palm downward, as if you are pressing something flat. Return to neutral.

Alternative Rolling Motion

For a smoother, more continuous movement, simply roll the forearm back and forth from palm‑up to palm‑down and back again, like turning a doorknob.

Repetitions

🔄 10 complete cycles (up–down–up), or 10 rolls in each direction

Key Points

Try to let the affected arm initiate as much of the movement as it can, even if that movement is only a mental effort or a very tiny flicker. The good hand is there only to guide and assist, not to take over completely. Pay attention to what you feel—even feeling a desire to move is a sign that neural pathways are being activated.

Integrating These Exercises Into Daily Life

Consistency is more important than duration. Performing these five exercises once or twice a day, every day, will produce better results than doing them for an hour once per week. Each exercise takes only a few minutes; the entire set can be completed in 10–15 minutes.

Best Practices for Success

  • Schedule exercises at the same time each day, such as after breakfast and before dinner.
  • Set up a comfortable, well‑lit space with a chair and a table.
  • Wear loose, comfortable clothing that does not restrict movement.
  • Breathe normally throughout each exercise—do not hold your breath.
  • If pain occurs, reduce the range of motion or the number of repetitions. Consult a therapist if pain persists.

What to Expect Over Time

In the first few weeks, you may notice that the arm feels less tight immediately after the exercises. Over several weeks, the resting stiffness may decrease, and you might be able to move the arm slightly more before resistance is felt. Active movement—the ability to initiate a small shoulder shrug or a finger wiggle—may begin to return. These are all signs of progress, even if they seem small.

When to Seek Additional Help

While these exercises are safe for most individuals in stage 2 stroke recovery, they are not a substitute for professional medical advice. If you experience any of the following, stop the exercises and consult your occupational therapist or physiotherapist:

  • Sharp, sudden pain in the shoulder, elbow, or wrist.
  • Increased swelling or redness in the affected arm.
  • New or worsening numbness or tingling.
  • Dizziness, shortness of breath, or chest discomfort during the exercises.

Additionally, a therapist can assess your specific movement limitations and may add or modify exercises based on your unique pattern of stiffness and weakness. Some individuals may benefit from splinting, electrical stimulation, or other interventions alongside these home exercises.

Conclusion

Post‑stroke arm stiffness and weakness can feel overwhelming, but the brain and body retain an extraordinary capacity to adapt and improve—even months after the stroke. The key is consistent, gentle, and properly supported movement. The five exercises described in this article—trunk rotation, shoulder rotation, gentle rocking, diagonal reaching (two directions), and forearm rotation—provide a comprehensive home program for restoring range of motion, reducing stiffness, and preparing the arm for self‑care activities. By protecting the shoulder, using the unaffected arm as a gentle guide, and moving slowly within a pain‑free range, stroke survivors can make meaningful progress toward regaining function. Every small reach, every slight rotation, and every conscious effort to follow the hand with the eyes is a step toward stronger, more independent living.
