Arm and Hand Exercises for People with Muscle Weakness That May Be Practised at Home

Why do people with muscle weakness need to practise arm and hand function? The arms and hands are important for reaching, grasping, holding, and managing everyday objects. Regular task-based practice may support function, but the activities should match the person’s diagnosis, strength, sensation, coordination, and safety. New or worsening weakness requires medical assessment.

Here are five suggested arm and hand activities presented by

Jenjira Chaiyajaem, OT an occupational therapistat KIN Rehabilitation & Homecare.

Exercise 1: Cylindrical Grasp

Suggested equipment: an empty plastic water bottle or lightweight cup.

How to practise a cylindrical grasp:

1. Begin with an empty, lightweight plastic bottle placed on a stable surface.

2. Add only a small amount of water to increase weight gradually if the person can hold it safely without pain, dropping, or excessive fatigue.

Exercise 2: Spherical Grasp

Suggested equipment: a soft ball that fits comfortably in the hand, such as a foam ball or tennis-sized ball.

How to practise a spherical grasp:

1. Pick up the ball and place it into a nearby basket.

2. Increase the reaching distance gradually. Throwing is optional and should only be used when sitting or standing balance, shoulder control, and the surrounding area are safe.

Exercise 3: Lateral Pinch

Suggested equipment: a light-resistance clip or clothespin.

How to practise a lateral pinch using the side of the thumb and index finger:

1. Begin with a small, light-resistance clip and attach it to a sheet of paper or thin card.

2. When the movement is controlled and comfortable, progress to a slightly larger or firmer clip. Stop if finger, thumb, or wrist pain develops.

Exercise 4: Object Rotation

Suggested equipment: a plastic bottle with a screw cap.

How to practise object rotation:

1. Begin with a lightweight bottle that has a large, easy-to-grip cap.

2. Progress to a smaller cap only when the movement is controlled. Keep the bottle supported on a table if arm weakness is significant.

Exercise 5: In-Hand Control

Suggested equipment: large tokens or coins and a container with a wide opening.

How to practise in-hand control:

1. Begin by picking up and placing one large token or coin into the container.

2. Progress to two or three pieces only if the person can manage them safely. Small objects should not be used without supervision when there is impaired sensation, vision, cognition, swallowing safety, or a risk of placing objects in the mouth.
