## What is gemgem400?

Enjoy Fun and Engaging Rehab Games at Home with Gemgem 400!

■ Who is it for?

Our game is designed for individuals with limited movement on one side of the body or those who need fine motor rehabilitation.

■ Why “400”?

Because performing 400 voluntary movements a day helps activate neuroplasticity in the brain, encouraging the formation of new neural pathways.

■ How effective is it?

The key is quantity and autonomy!
In other words, encouraging people to move more, on their own, is what really matters.

In fact, both caregivers and developers were amazed at the changes experienced by users who consistently played GemGem 400.

■ What kinds of games are included?

Jump, run, pop!
We offer a variety of adventures that everyone can enjoy — with new content being added regularly.

With the valuable feedback of caregivers, our service continues to improve every day.

■ Our goals are to:
	1.	Grow with joy through gaming
	2.	Build self-confidence
	3.	Support each person’s dreams for the future

Gemgem 400 cheers on everyone who is reaching toward new possibilities!

### 5/5 — 재미있게 재활할 수 있어요

*2025-05-29*

보통 운동 재활이 지루하고 의무감으로 하게 되는데 이 앱은 게임이 결합되어 있어서 자연스럽고 재미있게 할 수 있어요. 특히 아이들이 좋아하고 장애가 없더라도 소근육 발달이 느린 경우에도 도움되겠더라구요 추천해요!!

### 5/5 — 아주 큰 도움이 되어요

*2025-05-28*

매번 재활운동을 하러 가는게 큰 부담이었는데 집에서 할 수 있어서 좋아요

### 5/5 — 아이가 재밌어해요

*2025-05-28*

아이가 재밌어해서 좋아요
처음에 좀 어려워하더니 점점 적응해서 이제는 좋아해요.
게임하면서 계속 손을 움직이니까 유튜브 틀어주는 것보다 훨 나음

### 5/5 — 진짜 너~무 좋아요~

*2025-05-27*

아이가 재활 가는걸 유독 너무 힘들어하고 치료를 받아도 계속 제가 뭔가 아쉽더라구요.. 근데 잼잼 시작하고는 아이가 먼저 하고 싶어하고 안되던 동작이 되는게 제 눈으로도 보이니까 너무 좋아요~~감사합니다~^^

### 5/5 — 굿

*2025-05-26*

손을 다쳐서 움직이는게 불편했었는데, 그렇다고 재활 치료를 받으러다닐순 없어서 있다가 애기들용이라곤 하지만 재활운동 게임이라고 해서 다운받았어요!
잘 안움직여지던 걸 움직여야 게임이 되니까 동기부여되어서 움직였는데 계속 쓰니까 이제 불편함이 줄어들어드는게 느껴져서 좋네요!!

### 5/5 — 아이가 환측손을 잘 쓰지 않는데 사용해서 좋아요

*2025-05-26*

치료실에서 선생님이 추천해주셔서 숙제로 한 번 활용해봤습니다. 집에서 편하게 할 수 있다는 점이 좋았고 ^^ 안쓰던 손을 이렇게라도 쓰니 마음이 좀 놓이네요. 잘쓰고 있습니다 감사합니다

### 5/5 — 최초 소근육 증진게임

*2024-12-28*

아이의 소근육 발달을 위해 사용해봤습니다
스토리가있어 지루해하지않고 쭉 하는게 좋았고 
굳이 센터에 가지않고도 집에서나 여행가서나 어디서든 근육을 
쓸수있도록 한다는게 가장 큰 장점인거같아요
아이 발달 상태에따라 치료사님이 단계를 지정해주셔서
디테일한 부분이 특히 도움이 되었어요
더나아가 발목이랑 대근육 부분도 집에서
즐겁게 운동할수있는 게임 개발 쭈우욱 부탁드려요 ☺️
