Fisioterapi membantu gerakan sendi dan keseimbangan.

Indonesian usually does not use articles like English does.

So:

• fisioterapi = physiotherapy
• gerakan sendi = joint movement
• keseimbangan = balance

Whether something means a, the, or just a general idea is usually understood from context.

So Fisioterapi membantu gerakan sendi dan keseimbangan naturally means something like:

• Physiotherapy helps joint movement and balance
• or Physiotherapy helps the movement of the joints and balance

Indonesian normally leaves those article distinctions unstated.

Membantu means to help.

Its base word is bantu = help.
When Indonesian adds the prefix meN- to form an active verb, bantu becomes membantu.

So:

• bantu = help, assistance
• membantu = to help / helps

In this sentence, membantu is the main verb:

• Fisioterapi membantu ... = Physiotherapy helps ...

This meN- prefix is extremely common in Indonesian verbs.

Because gerakan and bergerak are different kinds of words.

• gerak = movement / move
• gerakan = a movement, motion, movement as a noun
• bergerak = to move, moving

In this sentence, the word after membantu needs to be a noun phrase, because the sentence is talking about what physiotherapy helps:

• gerakan sendi = joint movement
• keseimbangan = balance

So gerakan sendi fits well as a noun phrase.
Bergerak sendi would not sound right here.

Sendi means joint, especially a body joint such as:

• knee joint
• shoulder joint
• ankle joint

So gerakan sendi means joint movement or movement of the joints.

Depending on context, sendi can also appear in broader meanings like a connecting point or hinge, but in a medical or physical-therapy sentence, joint is the natural meaning.

It can mean either, depending on context.

Indonesian nouns often do not mark singular vs. plural unless it is important. So:

• sendi can mean joint
• or joints

In this sentence, English will usually translate it as joint movement or movement of the joints, which sounds more natural than forcing a strict singular/plural distinction.

If Indonesian wants to make plurality very explicit, it can use reduplication:

• sendi-sendi = joints

But in many normal sentences, plain sendi is enough.

Because Indonesian often expresses noun relationships by simply putting two nouns together.

So:

• gerakan sendi literally looks like movement joint
• but it means joint movement or movement of the joint(s)

This is very common in Indonesian. Another way to think about it is that the second noun modifies or specifies the first.

Similar patterns include:

• rumah sakit = hospital
• air minum = drinking water
• otot kaki = leg muscle

So you do not need a separate word for of here.

Keseimbangan means balance.

It comes from seimbang, which means balanced.
With the circumfix ke- -an, Indonesian forms an abstract noun:

• seimbang = balanced
• keseimbangan = balance

This pattern is very common:

• aman = safe

• keamanan = safety

• sehat = healthy
• kesehatan = health

So keseimbangan is an abstract noun meaning the state or concept of being balanced.

Because Indonesian sentence structure is different from English.

In this sentence, the main verb is already membantu = helps. So no extra helper verb like does is needed.

English:

• Physiotherapy helps joint movement and balance

Indonesian:

• Fisioterapi membantu gerakan sendi dan keseimbangan

Indonesian also often omits to be in sentences where English would use is/am/are, but that is not the issue here because this sentence already has a clear action verb: membantu.

Normally fisioterapi means physiotherapy as a field, method, or treatment.

So in this sentence:

• Fisioterapi membantu ... = Physiotherapy helps ...

If you wanted to refer to the person, Indonesian would usually say:

• fisioterapis = physiotherapist

So:

• fisioterapi = physiotherapy
• fisioterapis = physiotherapist

That difference is useful to remember.

Yes. That would sound a little more specific.

Your original sentence:

• Fisioterapi membantu gerakan sendi dan keseimbangan.

This is natural and concise, but it can sound slightly broad, like physiotherapy supports or helps with those things.

A more explicit version would be:

• Fisioterapi membantu meningkatkan gerakan sendi dan keseimbangan.
• Physiotherapy helps improve joint movement and balance.

So:

• membantu = helps
• membantu meningkatkan = helps improve

Both can be correct depending on how precise you want to be.

A simple pronunciation guide is:

• Fisioterapi → fee-see-oh-teh-RAH-pee
• membantu → mem-BAHN-too
• gerakan → guh-RAH-kan
• sendi → SEN-dee
• dan → dahn
• keseimbangan → kuh-suh-eem-BAHNG-an

A few helpful notes:

• e in Indonesian can vary, but learners often hear it as a soft uh or eh depending on the word.
• c is not in this sentence, but when it appears in Indonesian, it sounds like English ch.
• Stress in Indonesian is usually not as strong or dramatic as in English, even if guides mark one syllable for convenience.

It can mean either, depending on context, but in normal English translation here, and balance is best.

Because Indonesian usually does not mark definiteness with articles, keseimbangan can be interpreted generally or specifically from context.

So this phrase can be understood as:

• and balance
• and the ability to balance
• sometimes and the balance, if the context clearly points to a specific balance issue

But in a general health or therapy statement, balance is the most natural translation.

The basic order is:

• Fisioterapi = subject
• membantu = verb
• gerakan sendi dan keseimbangan = object/complement

So the structure is essentially:

• Subject + Verb + Object

That is very similar to English:

• Physiotherapy helps joint movement and balance

This is one reason the sentence feels relatively straightforward for English speakers, even though the details of Indonesian vocabulary and word formation are different.
